1. Overview

TGBQ high-voltage inverter soft starter cabinet adopts single-phase AC to AC stepwise frequency conversion method, gradually increasing the frequency and voltage fed into the motor stator from 1 Hz, so that the motor has the soft starting characteristics of small starting current and gradually increasing torque during the starting process, which reduces the capacity of the system distribution and avoids the impact during the starting, and compared with the present various soft starting methods(except for the inverter starting), the starting current is much smaller, and it can be started with load. The product is widely used in building materials, metallurgy, chemical industry, petrochemical industry, water conservancy and other industries.

2. Product Description

Operation of TGBQ inverter soft starter

Through the control of thyristor conduction angle to realize the variable voltage/pre-rate control can realize the motor terminal voltage/frequency start from a set starting value (≤ 10% Un, 1Hz) step by step boosting frequency up to <40%Un, Fn/3. Then turn to the system frequency, constant frequency boosting until reaching the rated voltage/frequency of the system. In this way, the starting current and starting torque can be optimally adjusted according to the transmission conditions.

In addition, the soft starter also provides a “soft stop” function. The rated motor voltage will be smoothly reduced while simulating the motor starting process. This prevents the drive from actually stalling, which is necessary for pump drives (where water hammer can be avoided) or conveyor belt drives.

3. Product Technical Characteristics

①Wide range of voltage applications: 3kV-13.8kV motor output power: 160kW-50MW.

②The starting process is smooth and shockless, can realize the starting mode of step frequency conversion and stepless voltage regulation, completely avoiding the case of the impact on the equipment and load of traditional soft start due to the adoption of surge voltage technology.

③Flexible starting mode, with multi-stage frequency conversion starting, voltage ramp starting, current ramp starting, constant current starting, etc., also have the function of free stop (soft start function)

④Can provide users with a variety of industrial network interface, to meet a variety of working conditions automation requirements.
