Summarize

GKG-12 (original model :KGS1-12) mining general type high voltage switchgear, is 3.6-12 kV three-phase AC 50Hz single bus and single bus section system of the complete set of power distribution device, mainly used in all kinds of mines, subways, wind power, residential, industrial and mining enterprises and enterprises distribution and electricity industry system user substation power, power supply and large high voltage motor start For the purpose of control, protection and monitoring. The switchgear meets the requirements of GB/T12173 "General Electrical Equipment for Mining Use", GB3906 and other standards. It has the interlocking function of preventing the push-pull circuit breaker with load from accidentally opening and closing the circuit breaker, preventing the grounding switch from closing the circuit breaker when the grounding switch is in the closed position, preventing straying into the live compartment, preventing the wrong closing of the grounding switch when the power is on, and preventing the circuit breaker from being in the working position Interlock function such as secondary plug off when set. The switch cabinet absorbs the advantages of various cabinet types at home and abroad in structure, overcomes the defects and deficiencies of old products, and introduces a kind of general high-voltage switch cabinet for mining to meet the power supply and distribution equipment used in coal mines, metal and non-metal mines underground and ground substation.
