KYN61-40.5 Armored metal-enclosed switchgear

SUMMARY

KYN61-40.5 armored metal-enclosed switchgear (referred to as switchgear) is our factory designed and improved switchgear based on the original product. It is adapted to a three-phase AC 50Hz power system for receiving and distributing electrical energy and for controlling, protecting and monitoring the circuit.

The switchgear has various functions to prevent misoperation, including preventing the handcart from moving with load, preventing the grounding switch from being energized, and preventing the charging interval from being mistaken.

This switchgear is equipped with ZN85, VN1 vacuum circuit breakers with excellent performance or ABB VD4 and HD4 series vacuum circuit breakers. The switchgear is a power distribution equipment with advanced technology, stable performance, reasonable structure, convenient use, safety and reliability.

Conditions of Use

● Ambient temperature: no higher than +40℃, not lower than -25℃;

● Altitude: no more than 1000m;

● Relative humidity: the daily average is not more than 95%; the monthly average is not more than 90%;

● There are no flammable gases, explosion hazards, serious contamination, chemical corrosion and frequent severe vibrations.

Special use environmental conditions

● When the switchgear is used under normal environmental conditions as specified in this instruction manual, the company and the user may negotiate and agree on special operating conditions that exceed normal operating conditions.

● In order to prevent condensation, the switch cabinet is equipped with a heater. When the switchgear is in standby, it should be put into use. Even in normal operation, you should pay attention to the application.

● The heat dissipation problem of the switchgear can be solved by additional ventilation.

Main feature

● The cabinet is made of aluminum-zinc plate and processed by CNC equipment. It is formed by bolting or riveting. The structure is fully assembled.

● It can be equipped with ZN85-40.5 vacuum circuit breaker handcart, VN1, VD4 or HD4 vacuum circuit breaker handcart. The main busbar of the switchgear can be connected without transition cabinet.

● The space of the cable room is sufficient, and the air clearance can be ensured to be more than 300mm. There is no need to install insulation spacers between the phases.
