with the protective functions of over loading, short-circuit, current leakage , insulation monitoring , over voltage ,low vol

Purpose

The mining explosion-proof(permanent magnet type)high-voltage vacuum power distribution equipment  is suitable to coal mine well with mixed explosive gas containing methane and coal dust.

In the power supply system of AC 50 Hz , rated voltage 10K V,6KV,3.3KV,rated current 630A,the product can control and protect the power supply system and start high voltage motor not frequently. The product has four types a,b,c,d to meet the usage of power receiving,Inter-connection, feeding,inter-coupled and direct control.

Technical Features
