Product Description

FZW-27.5/D1250-20 type outdoor high voltage AC vacuum load switch-isolation switch combination electrical appliance (hereinafter referred to as combination electrical appliance), single-phase column structure, novel structure, obvious visible fracture, the use of operating mechanism to drive the vacuum arc extinguishing chamber, with large breaking capacity, no arc when breaking and closing current, no fire and explosion risk, fast and frequent operation, Long electric life, maintenance-free and so on.
Combined electrical appliances are single-phase AC 50Hz, rated voltage 27.5kV single-pole outdoor high-voltage switchgear (altitude 2000 meters), widely used in electrified railway, used as load breaking current, no-load transformer, cable current, capacitor current and closing short-circuit fault current.

Product Parameters

No.	Item		Unit	Parameter
1	Rated voltage		KV	27.5
2	Rated current		HZ	50
3	Rated frequency		A	1250
4	Rated active load breaking current		A	1250
5	1 min power frequency withstand voltage		kV	95
6	Isolating fracture distance		mm	>400
7	Dynamic stable current		KA	31.5
8	Thermostable current		KA	12.5
9	Rated short-circuit opening/closing current		KA	12.5

Service Environment

Altitude: ≤2000m;
The load isolation switch is installed on an outdoor column, and must be able to break and close the normal load current of the line, and can integrate the function of the isolation switch to form an obvious visible fracture. The negative tea isolating switch can be installed in the power supply place of the locomotive depot, subdivision kiosk, return section, station yard and other sections, instead of the isolating switch installed on the column, eliminating the circuit breaker dedicated to cutting off the normal load current.
