XGN2-12(Z) Fixed metal enclosed switchgear

Product overview and scope of application:

Xgn2-12 (z) fixed metal enclosed switchgear (hereinafter referred to as switchgear) is used for receiving and distributing electric energy in 3.6, 7.2--12kv three-phase AC 50Hz systems, especially suitable for frequent operation occasions. Its bus system is single bus (and can derive single bus with bypass and double bus structure).

The switchgear meets the requirements of the national standard gb3906-91 "3--35kv AC metal enclosed switchgear" and the national standard IEC298, and has the "five prevention" locking function proposed by two parts.

The main switch of this switchgear adopts ZN28-12 and VS1 series vacuum circuit breakers, equipped with CD17 series electromagnetic operating mechanism or ct19 series spring operating mechanism, and the disconnector adopts gn30-12 rotary disconnector and gn22-12 high current disconnector series products.


Normal use conditions:

◆ ambient temperature: upper limit +40 ℃, lower limit -10 ℃;

◆ altitude: no more than 1000 meters. (if it is used in areas with an altitude of more than 1000 meters, it shall be handled according to the technical requirements specified in JB / z102);

◆ relative humidity: the daily average value is not more than 95%, and the monthly average value is not more than 90%;

◆ earthquake intensity: no more than 8 degrees;

◆ places without fire, explosion hazards, serious pollution, chemical corrosion and violent vibration.


Main technical parameters:

◆ technical data of switch cabinet (see the table below)

◆ technical data of circuit breaker and operating mechanism. This switchgear is mainly vacuum circuit breaker, and various schemes of SF6 circuit breaker can be specially designed

◆ the technical parameters of the grounding switch should be able to cooperate with the parameters of the corresponding disconnector, so the dynamic and thermal stability current and contact pressure of the grounding switch are consistent with the corresponding disconnector, but the distance between the fractures of the grounding switch is not less than 125mm.
