Multi Functional Vacuum Insulated Switchgear Overvoltage For Mining

Description:

KJZ4-630/1140 (600) mine use flame-proof and intrinsically safe multi-functional vacuum switchgear is designed for a belt conveyor installed at a continuous miner work face. It is suitable for underground mines on a. c. 50Hz, 1140V/660V power supply system. It integrates the protections along the belt conveyor, equipment start/stop control and other functions into one system for achieving start/stop control of belt conveyor, automatic belt tensioning, and belt winding control of the belt conveyor. It provides some basic protections and start/stop control, such as, belt misalignment, lockup, coal piling up, belt slip, etc., as well as function of loud-speaking telephone. It has 4KVA lighting power supplies. It can achieve central control over a great area by incorporation of data transmission and formation of a network.

Competitive Advantage:

DSP digital signal processing, CAN bus, self-adaptive detection, network interface, Chinese (English) character LCD display and self-diagnosis of fault.
