Overview

Mining general high voltage vacuum switchgear KLGC-12Z

Product Details

summary:

The KLGC-12Z mining general high voltage vacuum switchgear is mainly used in the power supply system of the central control room, yard, main ventilation duct, and main ventilation duct distribution room in places where there is no gas, coal dust, or explosion underground. It is used for the distribution, measurement, control, and protection of three-phase AC 50Hz, voltage 7.2kV or 12kV electrical equipment, to achieve the reception and distribution of electrical energy. It can also be used for direct starting or low-voltage starting of underground fans, pumps, and other high voltage motors through dry-type reactors. This switchgear is also suitable for ground substations in coal mines and power supply systems in metallurgy, petroleum, chemical industry, etc.

Compliant with technical standards: GB12173-90 "General Electrical Equipment for Mining", GB3836.1-2 "General Requirements for Explosion proof Electrical Equipment for Explosive Environments", and GB4208 "Classification of Protection Levels for Enclosures".

The main circuit breaker adopts the VKN-12 series vacuum circuit breaker independently developed by our company, or domestically produced circuit breakers such as VS1 and ZK1, and can also use handcart vacuum contactors such as CKG3.
