DNGCK Series Switch Cubicle--Guangdong Meilan Rilan Electrical Co., Ltd.

DNGCK Series Switch Cubicle

Application Range:

DNGCK Series Switch Cubicle is suitable for the primary distribution of the electric power system and the secondary distribution or control equipment taking asynchronous motor as the main control object of three-phase AC 50HZ, rated voltage 380V-660V of the factory and mining enterprises. It is also suitable for the group control system and site control device of the motors of the stations, docks, high-rise buildings, especially the power plant, transformer stations, petroleum, chemical engineering, metallurgy, mechanics, light industries production lines. If it is matched with suitable interface it can form the electric supply and distribution automatic control system with PC (Programme controller) or microcomputer processor.

This device is in conformity with the standards of IEC439-1 Low Voltage Complete Set Equipment and Control Equipment, GB7251.1-1997 Low Voltage Complete Set Switching Equipment, JB/T9661 Low Voltage Draw-out Type Complete Set Switching Equipment.

Main specs and technical parameters:

Structure characteristics
The main characteristics of the control cubicle is to be able to be assembled flexibly at will according to each unit circuit scheme required, and when there is a failure, the unit can be drawn out within very short time and replaced with a spare unit to be used continuously. The same units can be exchanged at any cubicles. The separated room of the unit is equipped with ventilation path, and the pressure releasing device is equipped on the top of the cubicle to be used to release the high voltage free gas produced when there is a failure in the distribution cubicle.
