What types of high voltage vacuum circuit breakers are available?
ZW8- 12/630A, ZW8- 12/ 1250A outdoor high-voltage vacuum circuit breakers are new outdoor high-voltage switchgear with rated voltage of 12KV, which are used to shunt and combine load current, overload current and short-circuit current in rural or urban power grids. It is an ideal product to replace oil-immersed circuit breaker to realize oil-free. Oil-immersed circuit breakers may still exist in China power grid, but they are outdated products. Silicone rubber is used for external insulation, which has reliable insulation and strong anti-pollution ability.
ZW8- 12 high voltage vacuum circuit breaker is equipped with spring energy storage operating mechanism, which can be operated manually, electrically and remotely. The disconnector can be installed on the side of the circuit breaker to form an outdoor high-voltage vacuum circuit breaker-outdoor high-voltage disconnector combined electrical appliance, which increases the visible isolation fracture and ensures reliable interlocking operation. According to the requirements of users, it can be combined with corresponding controllers to form AC high-voltage vacuum automatic recloser and automatic sectionalizer, which is an ideal equipment to realize the automation of distribution network. The structure of high voltage voltage transformer can be used externally or internally.
ZW 10- 12/630A outdoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor distribution equipment with rated voltage of 12KV and three-phase AC 50Hz, which is mainly used in rural power grid, urban power grid, railway, mine and port distribution systems, especially for outdoor overhead lines, load current, overload current and so on.
ZW20- 12 outdoor high-voltage vacuum circuit breaker adopts mature box sealing structure. Good sealing performance, not affected by external environment, is a maintenance-free product. Its spring operating mechanism adopts direct-acting chain main drive and multistage tripping system, which has high action reliability and is a good product of column circuit breaker. Outdoor distribution equipment with rated voltage 12KV and AC induction of 50Hz. It is mainly used for interrupting load current, overload current and short circuit current in power system. It is suitable for protection and control in substations and distribution systems of industrial and mining enterprises, and is more suitable for rural power grids and places with frequent operation. The product can meet the requirements of distribution automation system and complete the traditional reclosing function reliably and effectively when matched with the controller. The switch adopts vacuum arc extinguishing as arc extinguishing medium.
Characteristics of high voltage vacuum circuit breaker
1, special anti-condensation measures are adopted inside to ensure heat preservation in the box;
2. The rotation mode adopts patented technology, which is convenient and reliable to install and avoids the influence of mechanical failure on circuit breaking performance;
3, no oil, no air, small size, light weight, maintenance-free.
4. The breaking current is large, pollution-free and maintenance-free.
5. Manipulation can be electric or manual.
With the rapid development of China's economy, the power supply is increasing, and some weaknesses are gradually exposed, such as: too long power supply distance, high line loss rate, voltage quality is difficult to meet the requirements and so on. The introduction of foreign advanced technology into high-voltage vacuum circuit breaker is very suitable for the construction and transformation of urban power grid, rural power grid, mines, railways and other power equipment according to China's actual situation. Through the article, the characteristics and specific models of high-voltage vacuum circuit breakers are understood in order to better apply them.
