Description
Product Overview
ZW32-12 outdoor vacuum circuit breaker (hereinafter referred to as “vacuum circuit breaker”) is a three-phase AC 50Hz outdoor high voltage switch equipment, mainly used in the 10kV outdoor distribution system of the rural and urban network as the open or close load current, the overload current and the short circuit current, and can also be used in other similar places. ZW32-12 outdoor vacuum circuit breaker meet the national GB 1984-2003, IEC62271-100 “AC high voltage circuit breaker” and GB/T11022-1999 “Common technical requirements for high voltage switchgear and control equipment standards”.
Normal ambient condition
1. Ambient air temperature: -40°C~+40°C;
2. Altitude: no more than 2000m;
3. The ambient air may be polluted by dust, smoke, corrosive gases, steam or salt fog;
4. The wind speed does not exceed 34m/s (equivalent to 700Pa on a cylindrical surface);
5. Vibration or ground motion from the switchgear and control equipment is negligible;
6. Pollution Grade: Grade III;
7. Outdoor vacuum circuit breaker can be used in the normal use conditions different from the above regulations. At this time, the user should consult with the manufacturer and get the same opinion.
8. If beyond the above normal use conditions, the user will negotiate with the manufacturer.
Structure features
1. The breaker uses three-phase post structure whose breaking performance is stable and reliable. It doesn’t have combustion and explosion hazard. It doesn’t need any maintenance. It also has small volume, light weight and long service life, etc.
2. The breaker uses completely enclosed construction, so its air tightness is good which will contribute to improving damp proof and moist-proof performances. Especially, it is suitable for bitterly cold and moist areas.
3. Pillar and the three-phase current transformer adopts imported outdoor solid insulation epoxy resin, epoxy resin or indoor outsourcing of organic silicon rubber solid insulation; High and low temperature resistance, uv resistance, ageing resistance, etc.
4. Operating mechanism adopts miniaturization of the spring operating mechanism, energy storage motor power is small, points closing low energy consumption; Transmission by using real movement transmission mode, a small number of component parts, high reliability. Operating mechanism under seal regional institutions, solve the problem of the operating mechanism of corrosion, improve the reliability of the institutions.
5. Switching the breaker on and off can be done by manual or electric operation and remote-controlled operation. It can arrive at automated power distribution along with controller. It also can form a coincidence machine and segment machine with coincidence controller.
6. The breaker can be installed 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.
7. Isolation switch with three-phase tandem drive can be installed for the breaker. It has clear visible fracture when the isolating switch is off, and has the anti misoperation interlocking device between the outdoor vacuum circuit breaker body. When the outdoor vacuum circuit breaker is in the closing position, the isolation switch can not be opened and closed; the outdoor vacuum circuit breaker can only be operated when the isolating knife is completely closed or completely opened. Post insulator of arrester is installed. The maintenance is easy and safe.
