Series Mining General High-voltage Switch Cabinet

Product Introduction

General-purpose high-voltage switch cabinet for mining GKG: The main performance of the product: the rated voltage is 6/10KV, the maximum operating voltage is 7.2/12KV, THE rated current is below 2000A, the rated short-circuit breaking current is 31.5 KA, and the protection level is IP43.The products comply with GB/T12173-2008 "General Electrical Equipment for Mining" and GB3906-2006 "3.6KV〜40.5 KV AC Metal-enclosed switch cabinet and Control Equipment". The switch cabinet adopts central metal armor and assembled structure. It has individually spaced circuit breaker rooms, busbar rooms, cable rooms, and instrument rooms. It has a highly reliable interlocking device that fully meets the requirements of the "Five defenses". The shell is made of high-quality aluminum-zinc steel plate, CNC machining, and advanced multi-hemming technology, which has high strength and corrosion resistance. , Small size, light weight, high precision, and strong versatility of parts, this product can be matched with VS1 series or imported VD4 series vacuum circuit breakers, with wide applicability, high reliability, and maintenance-free. The hand car has working and test locations, and each location has positioning and display devices, which are safe and reliable.The hand car adopts modular building block technology, which can ensure that the hand car of the same specification is freely interchangeable, and the hand car of different specifications must not be entered.This product is small in size, each high-pressure chamber is equipped with a pressure relief channel, high safety, can be widely used in non-coal mine mountain variable power distribution, easy to transport, occupies a small area of the power distribution room, can reduce the cost of mining bunkers, applicability and economy are very good.The main configuration of the product: The switch cabinet mainly includes vacuum circuit breakers, microcomputer integrated protection devices, current (voltage) transformers, grounding switches, control devices, temperature and humidity controllers, operating overvoltage absorbers, busbars, etc., and can also be equipped with bus temperature measuring devices, automatic fire extinguishing devices, etc. according to user needs.；

Composition and Meaning of Product Model

Use Environmental Conditions

Normal working conditions should be within the scope of the following provisions：
