ASN3-12 air-insulated metal-clad enclosed switchgear is a new mv switchgear on the basis of introducing advanced techniques from foreign, abstracting our experiences in manufacturing the center located switchgear and assembling the world top class numeral controlled equipments. It is major used in 3.6~12kv 3-phase ac50/60hz power system to receive and distribute electrical power. Also it is used to control, protect and monitor the circuit.
1.The surfaces of conductors in the primary circuit are all disposed with vulcanization process. Thus the insulation lay have the characteristic of good attachment, high temperature endurance and even surface comparing with the static electricity process.
2.The frame is made of aluminum-clad zinc board together with rivet nut and high strength bolt.
3. Can be fitted with vn3 series center located high voltage ac vacuum circuit breaker.
4. With the function of manual urgent open switch, the operation is more convenient.
5. Equipped with new ek6 earthing switch, which make the operation convenient and the maintenance easily.
6.All switch operation is proceed with the door of high voltage compartment closed. Also the switchgear has the function of forcible closing the door and the safety is higher. The door can endure the inside fault current.
ASN2-24 air-insulated metal-clad enclosed switchgear is a necessary power distribution equipment in 24kV 3-phase AC50/60Hz power system. It is used in power generator, substation, factory and high building as a equipment of receiving and distributing electrical power. Also it is used to control, protect and monitor the circuit. The switchgear accords with the standard of GB3906, DL/T404 and so on.
1. Busbar is covered with shrinkable insulated material or disposed with epoxy, which make the electrode improved and the body of the switchgear compact.
2. The frame of switchgear is made of top quality aluminum-clad zinc plate through rivets and has characteristic of higher strength, rapider assembled efficiency and more artistic appearance.
3. According to functions the trolley can be divided into circuit breaker trolley, voltage transformer trolley, metering trolley, isolation trolley. The same kind trolleys can be exchanged freely.
4. Can be fitted with VN2 series center located high voltage AC vacuum circuit breaker.
5. There are clapboards between function compartments and individual pressure relief passage.
6. The instrument board is with applicable inclined angle so the operation and observation are more convenient.
7. The instrument compartment is a knock-down module, which not only improve the prettiness and safety of secondary wires but also make the maintenance and overhauling more convenient.
A6 1P circuit breaker switch belongs to the advanced level of the nineties in the world. They have protective functions as shortage and overloading,and are used in lighting distribution system in industry,commerce and dwelling,and protect fractional electric motors.And they also have many merits of high protective grade(up to IP20),high breaking capacity,good reliability of sensitive action,convenient multi-pole assorting,long using life etc.They are mainly adapted to the circuit of AC50Hz, 230V in single pole,400V in double,three on four poles for protecting overload and shortage.Meanwhile,they are also used in turning on or off the electric apparatus and lighting circuit under the normal condition.
