fuse disconnect switch(DS) outdoor high voltage isolate switch is the high voltage switch equipment of composite strudcture, is suitable for outdoor 22KV line net with voltageand no load, to make opening and close. With type manual operate machinery, can avoid earth line with power and composite flash-locks ets.
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.
In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.
A surge arrester is a protective device for limiting voltage on equipment by discharging or bypassing surge current. An arrester does not absorb lightning or stop lightning. It diverts the lightning, limits the voltage and protects the equipment installed in parallel
