Outdoor Pole-mounted Vacuum Circuit Breaker

Detailed Product Description

Outdoor Pole-mounted Vacuum Circuit Breaker

1eneral introduction

   TYPE ZW2-12 outdoor AC high-voltage vacuum breaker (breader for short in the following) is an outdoor electric power distribution cquipment for triphase currcnt whose rated voltage is 12KV and 50Hz(60Hz).It is mainly used fou the load current,excess current and short-cireuit current during switching distribution network on and off in the electric power system. It is suitable for protecting and controlling the transformer substation and distribution system used in industrial and mining enterprises,and more suitable for the rural power network and areas where the power network is operated frequently, especially,it suitable for the reconstruction of urban and rural power network.

4Main feature

1The breaker uses three-phase post structure whose drop-out performance is stable and reliable.It doesnt have combustion and explosion hazard.It doesnt need andy maintenance. It also has ,etc.d

2The breader rucs completely enclosed construction, so its air tightness is good which will contributc to improving dampproof and moist-proof performances. Especially, it is suitable for bitterly cold and moistarcas.

3The importcd insulating outdoor epoxy resin solid is used fou three-phase post and current transformer. It is frigostabile,fire resistant, ultraviolet ray resistant and aging resistant.

4Miniaturized spring controlling mcchanism is used as the controlling mechanism.The energy consumption used by switch is low. The energy consumption used by switch is low. The drive of the controlling mechanism uses direct-acting transmittal mode. There are few parts of the switch, so the reliability is high. The controlling mechanism locates in the scalcd box, avoid corrosion problems and increase the reliability of controlling mechanism.

5Switching the breader on and off can be done by manual or electric operation and remore-controllde operation. It can arrive at automated power distribution along with controller. It also can form a coincidence machinc and segment machine with coincidence controller.

6The breader can be installde with two-phase or three-phase CT, automatic tripping protection for oversupply current and intelligent controller for analysis of information. According to the customers requirement, it also can be installed with measuring CT.

7Isolating switch and therr-phase tandem drive can be installd for the bueaker. It has clear visiblc frcture when the isolating swith is off. Post insulator of arrester is installde(see figure). The maintenance is easy and safe..

8Wcight of the breader:95kg(with insulator),80kg(without insulator).
