FZRN25-12D/T200-31.5 Load Switches

nbsp;Uses: FZRN25-12D/T200-31.5 indoor-exchange high-pressure vacuum switch - electrical fuse is the combination of three-phase AC 50Hz, rated voltage of 12kV indoor installations for industrial and mining enterprises as a power distribution substation and so on, for load Control and short-circuit protection. Electrical equipment such as transformers on the protection of the use of more reliable than the circuit breaker, especially suitable for ring network, the radiation power supply units and two-box-type substation. The present facilities are in compliance with the standards: GB16926-97 "the exchange of high-voltage switch - combination of electrical fuse" and IEC420 (1990) "the exchange of high-voltage switch - combination of electrical fuses"Structural characteristics: 1. Products of the Vacuum Interrupter, stable and reliable performance, long-life power, breaking the number of high closing, the ability to cut, easy to maintain operations

2. Switches into body and actuator in one, set isolation switch, load switch, one on the open ground, compact, small size

3. Direct-action fracture isolation and vacuum interrupter arranged in series, moving, heat-stable high-current parameters; unique joint operating procedures as required, to complete a one-time operation

4. Tapered contact static, insulating covers and valve structures, the complete separation of the bus load and switch unit;5. Vacuum load switch, grounding switch, valve, switch doors, in strict accordance with the "five anti-" mechanical interlock to prevent the misoperation, safe and reliable

6. Spring of operations energy-body electric closing minutes, can also be operated manually at closing, to facilitate the realization of three remote control requirements

7. Pm closing operations AC-DC power supply can be dual-use

8. Manually switch on sub-conventional operations in the right side load switches can also be based on user needs to provide a positive operation or left operation.
