Soft starter is a kind of motor control equipment that integrates soft start, soft stop, light load energy saving and multifunctional protection. It realizes the smooth starting motor without impact during the entire starting process, and can adjust various parameters during the starting process, such as current limit value and starting time, according to the characteristics of the motor load.
ATS 48 Schneider Soft Starter-Soft Stop Unit is a controller with 6 thyristors for torque-controlled soft start and soft stop of three-phase squirrel-cage asynchronous motors with a current range of 17 to 1200A.
The soft starter is a product developed to bridge the gap between the star-delta starter and the inverter in functionality and price, so it is said to be a transition product. With the gradual reduction of the cost of the inverter, the market space for soft starters will become smaller and smaller. As for whether the soft starter will disappear completely in the future, it needs further verification by the market. As far as the current situation is concerned, soft starters still have their own living space. When the motor running load power is more than 80%, the soft starter is still the best, most practical and most economical. In the next few years, the market for soft starters will still grow steadily, but the growth rate is much lower than the growth rate of the inverter market. As the market competition intensifies, a number of small-scale and weakly competitive enterprises are eliminated. Starter market concentration will further increase. The application of soft starter products only involves many areas of China's national economy. Electricity, metallurgy, building materials, machine tools, petrochemicals and chemical industry, municipal administration, and coal are seven major industries.

Thermal relays are mainly used for overload protection of electrical equipment (mainly motors). Thermal relay is an electrical appliance that works by the principle of current thermal effect. It has an inverse time-lapse action similar to the allowable overload characteristic of a motor. It is mainly used in conjunction with a contactor to protect three-phase asynchronous motors from overload and phase failure In actual operation, asynchronous motors often encounter overcurrent (overload and phase failure) caused by electrical or mechanical reasons. If the overcurrent is not serious, the duration is short, and the winding does not exceed the allowable temperature rise, this overcurrent is allowed; if the overcurrent situation is serious and the duration is long, it will accelerate the aging of the motor insulation and even burn the motor. A motor protection device shall be provided in the motor circuit. There are many types of commonly used motor protection devices. The most widely used is the bimetal thermal relay. The bimetallic thermal relays are all three-phase, with two types of phase-open protection and without phase-open protection.
1. Lightning characteristics
Lightning protection includes external lightning protection and internal lightning protection. External lightning protection is mainly based on lightning receptors (lightning rods, lightning protection nets, lightning protection belts, lightning protection lines), down conductors, and grounding devices.The main function is to ensure that the building body is protected from direct lightning strikes and will likely hit. Lightning from buildings is discharged into the ground through lightning rods (belts, nets, cables), down-conductors, etc. Internal lightning protection includes measures against lightning induction, line surge, ground potential counterattack, lightning wave intrusion, and electromagnetic and electrostatic induction. The basic method is to use equipotential bonding, including direct connection and indirect connection through SPD, so that metal bodies, equipment lines and the ground form a conditional equipotential body, which will shunt and induce internal facilities caused by lightning and other surges. Lightning current or surge current is discharged into the ground, thereby protecting the safety of people and equipment in the building.
Lightning is characterized by very fast voltage rises (within 10 μs), high peak voltages (tens of thousands to millions of volts), large currents (tens to hundreds of thousands of amps), and short maintenance times (tens to hundreds of microseconds) ), The transmission speed is fast (propagating at the speed of light), and the energy is very huge, which is the most destructive type of surge voltage.
2 Classification of Surge Protectors
SPD is an indispensable device for lightning protection of electronic equipment.Its role is to limit the instantaneous overvoltage that penetrates into power lines and signal transmission lines to a voltage range that the equipment or system can withstand, or to discharge a powerful lightning current into the ground Protect the protected equipment or system from impact.
2. 1 Classification by working principle
Classified according to their working principle, SPD can be divided into voltage switching type, voltage limiting type and combination type.
(1) Voltage switching type SPD. It shows high impedance when there is no transient overvoltage. Once it responds to the lightning transient overvoltage, its impedance changes to low impedance, allowing the lightning current to pass through. It is also called "short-circuit switching SPD".
(2) Voltage-limiting SPD. When there is no transient overvoltage, it is high impedance, but with the increase of surge current and voltage, its impedance will continue to decrease, and its current and voltage characteristics are strongly non-linear, sometimes called "clamping SPD".
(3) Combined SPD. It is a combination of voltage switch-type components and voltage-limiting type components, which can be displayed as voltage-switching type or voltage-limiting type or both, depending on the characteristics of the applied voltage.
2. 2 Classification by purpose
According to their usage classification, SPD can be divided into power line SPD and signal line SPD.
2. 2.1 Power Line SPD
Because the energy of lightning strikes is very huge, it is necessary to gradually release the energy of lightning strikes to the ground through the method of hierarchical discharge. Install surge protectors or voltage-limiting surge protectors that have passed the Class I classification test at the direct lightning protection zone (LPZ0A) or at the junction of the direct lightning protection zone (LPZ0B) and the first protection zone (LPZ1). First-level protection, release direct lightning current, or release the huge energy conducted when the power transmission line is subjected to direct lightning strike. Install a voltage-limiting surge protector at the junction of each zone (including the LPZ1 zone) after the first protection zone, as a second, third or higher level protection. The second-level protector is a protective device for the residual voltage of the previous-level protector and the induced lightning strike in the area. When the large-scale lightning energy absorption occurs in the front-level, a part is still quite large for the device or the third-level protector. The energy will be conducted and need to be absorbed by the second-level protector. At the same time, the transmission line passing the first-level lightning arrester will also induce the electromagnetic pulse radiation of the lightning strike. When the line is long enough, the energy of the induced lightning becomes large enough, and a second-level protector is required to further discharge the energy of the lightning strike. The third level protector protects the residual lightning strike energy passing through the second level protector. According to the withstand voltage level of the protected equipment, if two levels of lightning protection can be used to limit the voltage lower than the withstand voltage level of the device, only two levels of protection are needed; if the withstand voltage level of the device is low, four levels or More levels of protection.
When choosing SPD, you first need to understand some parameters and how it works.
(1) The 10 / 350μs wave is a waveform that simulates a direct lightning strike, and the waveform energy is large; the 8 / 20μs wave is a waveform that simulates lightning induction and lightning conduction.
(2) The nominal discharge current In refers to the peak current flowing through the SPD, 8 / 20μs current wave.
(3) The maximum discharge current Imax is also referred to as the maximum flow rate, which refers to the maximum discharge current that the SPD can withstand once with 8 / 20μs current wave.
(4) Maximum continuous withstand voltage Uc (rms) refers to the maximum effective value of the AC voltage or DC voltage that can be continuously applied to the SPD.
(5) Residual voltage Ur refers to the residual voltage value at the rated discharge current In.
(6) The protection voltage Up characterizes the voltage characteristic parameter between the SPD limiting terminals. Its value can be selected from the list of preferred values and should be greater than the highest value of the limiting voltage.
(7) The voltage switch type SPD mainly bleeds 10 / 350μs current wave, and the voltage limiting type SPD mainly bleeds 8 / 20μs current wave.
The most common failure of Schneider inverters is that there is no display when they are powered on. The switching power supply of this series of inverters uses a UC2842 chip as a waveform generator. Damage to the chip will cause the switching power supply to fail to work, which will not display properly. The abnormal working power supply will also make the switching power supply unable to work normally.
The most common faults of Schneider inverters are the damage of the drive circuit and the IGBT module. The drive circuit is driven by a pair of tubes to drive the IGBT module. This pair of tubes is also the most easily damaged component. Due to the damage of the IGBT module, high-voltage and large-current flows into the driving circuit, and the components of the driving circuit are damaged.
Commonly used reactors in power systems are series reactors and parallel reactors.
The series reactor is mainly used to limit the short-circuit current. There are also series or parallel capacitors in the filter to limit the higher harmonics in the power grid. Reactors in 220kV, 110kV, 35kV, and 10kV power grids are used to absorb the capacitive reactive power of cable lines. The operating voltage can be adjusted by adjusting the number of shunt reactors. EHV shunt reactors have multiple functions to improve the operating conditions of reactive power in power systems, including:
1. Capacitive effect on light no-load or light-load lines to reduce power frequency transient overvoltage;
2. Improve the voltage distribution on long transmission lines;
3. Make the reactive power in the line as balanced as possible at light load to prevent the unreasonable flow of reactive power and also reduce the power loss on the line;
4. When large units and systems are juxtaposed, the power-frequency steady-state voltage on the high-voltage bus is reduced to facilitate the juxtaposition of generators in the same period;
5. Prevent the self-excitation resonance phenomenon that may occur in the long line of the generator;
6. When the neutral point of the reactor is passed through the small reactor grounding device, the small phase reactor can also be used to compensate the phase-to-phase and phase-to-ground capacitance of the line to accelerate the automatic extinguishment of the latent supply current for easy adoption schneider.
The wiring of the reactor is divided into two ways: series and parallel. Series reactors usually function as current limiters, and shunt reactors are often used for reactive power compensation.
1. Half-core dry-type parallel reactor: In the ultra-high-voltage long-distance power transmission system, it is connected to the tertiary coil of the transformer. It is used to compensate the capacitive charging current of the line, limit the system voltage rise and the operating overvoltage, and ensure the reliable operation of the line.
2. Half-core dry series reactor: Installed in the capacitor circuit, starting when the capacitor circuit is put in.
