QGC-12 switchgear for rated voltage 12kV, three-phase AC 50Hz, rated current 630A in the power system as the acceptance and distribution of electrical energy, widely used in the power grid as a ring network power supply unit and terminal equipment. The product adopts modular design and can be arranged arbitrarily according to different design schemes to realize the perfect combination of common box unit and extended unit. The product is a completely sealed system, the main circuit switch body and various live parts are enclosed in a stainless steel shell filled with a certain pressure of SF6 gas, the entire switch device is not affected by the external environment, to ensure reliable operation and personal safety, and to achieve a maintenance-free.
Conform to standard
Products in line with IEC60298, GB/T3906, DL/T404 and other latest standards.
Structural features
The product has different modules including load switch unit (C), load switch fuse combination unit (F), circuit breaker unit (V), metering cabinet unit (M), bus PT unit (PT), etc., which can be combined into ring network switching equipment with different schemes through various standard unit modules. The primary live part (main bus) and the switch body of the product are sealed in a gas box welded with stainless steel plates. The main circuit is connected to the outside through a sleeve on the gas box, and can be connected to incoming and outgoing cables through a fully insulated and fully shielded detachable connector. The protection level of the gas box reaches IP67. The inside of the gas box is not affected by the external environment and has short-term flood resistance and condensation resistance functions. It has perfect mechanical interlocking device to effectively prevent misoperation.
