The high-voltage soft start cabinet with incoming line is an integrated design of switch cabinet, high-voltage soft start cabinet and bypass vacuum contactor. It has small overall size and convenient installation, and can meet the requirements of merging with other high-voltage switch cabinets.
Functions and features of integrated high-voltage solid-state soft starter:
● the cabinet body adopts kyn28 imitation cabinet structure, and the material is aluminum coated zinc plate, which is assembled through multiple bending process, with high and low pressure separation and high safety;
● the cabinet body is consistent with the standard switchgear, which can be easily combined with other high-voltage switchgear on site, so that the overall system layout is reasonable and beautiful, and the highly reliable interlocking device meets the requirements of "five prevention".;
● the internal configuration of the cabinet includes microcomputer integrated protector, network side vacuum circuit breaker, bypass vacuum contactor and three-phase thyristor valve group, without additional switch cabinet;
● the soft start control system adopts high-performance micro control chip to make the control of the device real-time, efficient, reliable and stable;
● the cabinet is equipped with anti condensation and anti-corrosion measures, the front door is equipped with observation window, and the high-pressure chamber is equipped with pressure relief channel to ensure personal safety;
● protection function: microcomputer integrated protector protection function, soft start control system protection function: thyristor static and dynamic voltage sharing, phase loss, overvoltage, undervoltage, starting overcurrent, running overcurrent, starting overload, running overload, underload, current imbalance, starting timeout, external input fault detection, etc. the protection action time can be set;
● various start and stop modes: current limiting + ramp start, current limiting start, inching, sudden jump + voltage ramp start, etc. free stop and soft stop modes are available;
● display function: Chinese large screen LCD system, easy to operate and more humanized;
● communication function: complete electrical isolation, RS485 communication, Modbus RTU protocol, and centralized control by upper computer;
● it has external control start, stop, reset input and fault, bypass, programmable relay output, and 4-20mA analog output.
