GW5-126-1250 High -Voltage Isolating Switch
Product overview
Outdoor isolating switch of AC frequency 50 Hz outdoor high voltage apparatus equipment for high-pressure line in no case load close, as well as to be high voltage circuit breaker generatrix, repair electrical equipment and charged high voltage lines of electrical isolation with, can also be used to open and close the small electric current may be inductance
1. Altitude: 3000m;
2. Ambient temperature: -25 ~+40;
3. Wind speed: 35m/s;
Rated voltage: 40.5KV-126KV
Isolating switch, is suitable for use in AC frequency 50 Hz, AC rated voltage 660 V and below. General in the circuit breaker before and after a group of the installation 2 face isolation switch, the purpose is to make all the power circuit breaker and isolation, form the obvious disconnect point; Because the original circuit breaker USES is the oil circuit breaker, oil circuit breaker need often overhaul, the two side will have obvious disconnect point, so as to facilitate the maintenance; Usually, qualify from top bus through the switch ark downward power supply, in front of a circuit breaker need isolation switch is to isolate and power supply, but sometimes, the back of the circuit breaker to also have the possible, such as through the other of the loop send, capacitors device against send, reason behind the circuit breaker also need a group of isolating switch.
DC rated voltage 440 V and below and rated current to 315 V. General electric transmission operation: First and isolating switch, close circuit breaker or load after class switch; Isolating switch power operation: The first to disconnect circuit breaker or load class switch, isolating switch off. When choosing and other electrical equipment everything, is rated voltage and rated current dynamic stability, current, the thermal stability of current, compliance with all use situation the need.
In the industrial enterprise power distribution equipment, for not frequent manually placed and points off circuit and isolation power use.
1000 A and above are for isolation power, can't load points off circuit. Isolating switch function without the current load disconnect, circuit. That makes the maintenance of the equipment and power have obvious disconnect point, to ensure the safety of the maintenance staff, isolating switch does not have special arcing device can't cut off the load current and short circuit current, so must be in a circuit breaker disconnect in the circuit can operate isolating switch.
Ordering information: Ground state (single ground, double ground), operating status (manual, electric operation)
