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.

ATS01 Soft Starter
ATS01 is a small current soft starter with relatively few control functions. It is generally used in low power machinery.
working principle:
Soft starter is a novel motor control device that integrates motor soft start, soft stop, light load energy saving and multiple protection functions. It is called Soft Starter abroad. The soft starter uses three opposite parallel thyristors as voltage regulators, which are connected between the power supply and the motor stator. Such a circuit is, for example, a three-phase fully controlled bridge rectifier circuit. When a soft starter is used to start the motor, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully turned on. The motor works on the mechanical characteristics of the rated voltage to achieve smooth start, reduce the starting current, and avoid starting overcurrent trip. When the motor reaches the rated number of revolutions, the start-up process ends. The soft starter automatically replaces the thyristor with a bypass contactor to provide the rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor and extend the service life of the soft starter. , Improve its work efficiency, and make the grid avoid harmonic pollution. The soft starter also provides a soft stop function. The soft stop is opposite to the soft start process. The voltage gradually decreases and the number of revolutions gradually decreases to zero to avoid the torque shock caused by free stop.
Control principle:
The soft starter controls the output voltage by controlling the conduction angle of the thyristor. Therefore, the soft starter is essentially a step-down starter that can be automatically controlled. Because it can arbitrarily adjust the output voltage for current closed-loop control, it is better than the traditional step-down starter methods (such as string resistor start, autotransformer start Etc.) have more advantages. For example, starting a variable torque load such as a fan and a pump at full load, implementing a soft stop of the motor, and applying it to a pump can completely eliminate the water hammer effect.
Main application:
The AC squirrel cage asynchronous motor is widely used in the dragging of mechanical equipment because of its simple structure, convenient control and high efficiency. Most of the mechanical equipment in civil buildings, such as fire pumps, spray pumps, domestic pumps, refrigeration units, etc., are AC squirrel cage asynchronous motors. When the building has a high number of floors or a large scale, the rated power of the motors of these mechanical equipment is usually large, such as the fire pump's rated power is usually between 55kW-150kW. During the starting process of these devices, a larger starting current will be generated, resulting in a larger voltage drop. Therefore, proper selection of the starting method has important significance such as reducing the power supply capacity and ensuring the reliability of the building power supply. Because of this, soft starters have broad prospects in the application of civil construction.
The main function:
1. Overload protection function: The soft starter introduces a current control loop, so it can track and detect the change of motor current at any time. By increasing the setting of the overload current and the inverse time control mode, the overload protection function is realized. When the motor is overloaded, the thyristor is turned off and an alarm signal is issued.
2. Phase loss protection function: During operation, the soft starter detects the change of the three-phase line current at any time, and once a current interruption occurs, a phase loss protection reaction can be made.
3. Overheating protection function: The temperature of the thyristor radiator is detected by the internal thermal relay of the soft starter. Once the temperature of the radiator exceeds the allowable value, the thyristor is automatically turned off and an alarm signal is issued.
4. Measurement circuit parameter function: When the motor is working, the detector in the soft starter always monitors the motor running status and sends the monitored parameters to the CPU for processing. The CPU analyzes, stores, and displays the monitored parameters. Therefore, the motor soft starter also has the function of measuring loop parameters.
5. Other functions: Through the combination of electronic circuits, other interlocking protections can be realized in the system.
