XGN2-12 fixed metal switch equipment
Xgn2-12 box type with formulary will belongs to a closed switch equipment (hereinafter referred to as switchgear) for 3, 6, 10kV three-phase AC 50Hz system as receiving and distributing electric energy use, especially suitable for occasions of frequent operation, the bus system for single bus; and sent a single busbar with bypass and dual bus structure.
The switch cabinet meets the requirements of national standard GB3906 and international standard IEC298, and there are two "five anti" locking functions. The system has the advantages of reasonable structure, high safety and reliability, simple operation, convenient maintenance, and the like, and the 10kV level fixed switch is not prepared to replace the product.
The main switch of the switch cabinet can adopt ZN28A-IO series vacuum circuit breaker, and other series vacuum circuit breaker. Can be equipped with CD10 series and CT19A series electromagnetic spring actuator. Isolation switch using GN30-IO rotary isolation switch and GN22- 10 large current isolation switch products.
Product use environmental conditions
The environment temperature: +40 degrees limit
Lower limit of -25
The altitude does not exceed 1000m, when more than 1000m, and f according to the special requirements of production.
The relative temperature: average value is less than 95%, on average less than 90%;
The earthquake intensity does not exceed 8 degrees;
- no fire and explosion danger, serious powder, chemical corrosion and severe vibration of the place.
technical data
Technical data of the breaker and operating mechanism can be found on the circuit breaker and operating mechanism of sample.
The technical parameters of isolation switch is shown in Table 1, table 2 (rotary isolating switch)
The grounding switch technical data
The technical parameters of grounding switch matched with the corresponding isolation switch parameters. So the grounding switch of dynamic stability and heat stability constant current, the contact pressure with the corresponding isolated switch consistent, but grounding switch between fracture distance of not less than 125 mm
