Mining general low-voltage vacuum switchgear KLGD-1Z

summary:

KLGD-1Z general low-voltage vacuum switchgear for mining is mainly used in the bottom yard, main air inlet duct, and main air inlet roadway of low biogas mines. The electromechanical chamber serves as the input, output, connection, lighting, and hoist (low-voltage) electrical control for the low-voltage side of the substation, and can be used in conjunction with KLGC general high-voltage vacuum switchgear for mining. It can also be used for controlling power, distribution, lighting, motors, and other equipment in other similar industrial plants, mines, ports, metallurgy, chemical industries, 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".
Electrical components can be selected according to user requirements. The switch cabinet is equipped with ZLDB-3X (T) intelligent Chinese display comprehensive protector for mining feed switches, which can achieve multiple protection functions such as main switch protection, selective leakage protection for branch switches, leakage lockout, overload short circuit, three-phase imbalance, undervoltage, etc.
