Product Description

Introduction
SZYQ series liquid resistance starting device is a new generation of starting control device successfully developed to further improve the starting performance of large and medium-sized winding asynchronous motors. By inserting a liquid resistance in series into the rotor circuit of the controlled motor, it automatically starts when the motor starts. It is put in and automatically, steplessly and continuously cut off within a predetermined time, overcoming the large impact current of old-fashioned starting control equipment such as frequency-sensitive rheostat, oil-immersed rheostat, cast iron resistor (generally about 3 to 5 times the rated current), starting It allows the motor to start smoothly and increase speed evenly under ideal starting current conditions, which has significant effects on protecting the motor, electrical equipment, power grid and energy saving. This equipment is carefully designed in terms of starting, stopping, fault protection, contact, alarm, display, etc. Compared with other old-fashioned starters, it has a high degree of automation, small starting current (generally less than or equal to 1.3 times the rated current), electrical It has the characteristics of small mechanical impact and is particularly suitable for heavy-load starting. It can start smoothly even with low grid voltage, which reduces the capacity of the transformer. It is currently the most ideal for heavy loads such as ball mills, elevators, crushers, compressors, fans, and water pumps. starter control equipment.

6. Working Principle

The SZYQ series liquid resistance starting control device uses a special medium aqueous solution as a resistor. In a specially designed liquid resistance box, a plate is introduced as an electrode and connected in series to the motor rotor circuit. When the motor starts, a small power servo motor drives the plate to move to change the relative distance of the plate, so that the liquid resistance (connected in series to the rotor circuit) changes steplessly from large to small, thereby achieving smooth starting of the motor.
