Abstract
The utility model relates to an enclosed type outdoor high pressure permanent-magnet structure vacuum circuit breaker which is widely applied for disparting and joining the normal load, the overload and the short-circuit current of 50 Hz and 12 KV outdoor three-phase alternating current transmission and distribution circuit, in particular to the frequent manipulation occasion. Three insulating casings are fixed to a pedestal, the lower portion of every insulating casing is separately fixed with a suit of permanent-magnet structure, one end of the power take-off shaft of every permanent-magnet structure is separately connected with high-intensity insulating draft bar, the other end of the insulating draft bar is separately hinged on the movable bunter of the vacuum extinction chamber, the movable bunters are fixed to a lower outlet terminal through the soft connection, the static bunter of the vacuum extinction chamber is fixed to an upper inlet wire terminal through the electric connection. The utility model not only has compact conformation, small bulk, light weight, but also has the advantages of no oil and gas, environment friendly, no detonate explosion, precious opening and closing movement, safe and reliable operation and little maintenance workload.
Description
(1), technical field
The utility model relates to a kind of fixed sealing type outdoor high-voltage permanent magnetic actuator vacuum circuit breaker, is widely used in the outdoor three-phase alternating current electric line of 50Hz, 12kV deciliter normal duty, overload and short circuit current, is particularly useful for the occasion of frequent operation.
(2), background technology
At present, the outdoor high voltage circuit breaker of domestic 10kV electric pressure adopts electromagnetism electric spring stored energy operating mechanism more, and invests outside the breaker body.Because its mechanism's complexity, middle transmission link is various, in addition can not integral sealing, so be subject to environmental pollution and spontaneous corrosion, make and adhere to dirt or the serious operating mechanism of corrosion easily produces misoperation or " getting stuck " malfunctioning phenomenon, and influence normal power transmission and distribution.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of fixed sealing type outdoor high-voltage permanent magnetic actuator vacuum circuit breaker, not only compact conformation, volume are little, in light weight for it, and possess do not have the no gas of oil, be beneficial to environmental protection, the danger of no combustion explosion and a deciliter action accurately put in place, characteristics safe and reliable to operation, that maintenance workload is few.
The technical scheme in the invention for solving the technical problem is: fix three insulation crusts on the pedestal, every interior lower end of insulation crust is fixed a cover permanent magnet mechanism respectively, one end of the power output shaft of each permanent magnet mechanism connects the high strength insulated tension pole respectively, the other end of each insulated tension pole is hinged on respectively on the movable feeler lever of each vacuum interrupter, each movable feeler lever is separately fixed at by being flexible coupling on lower wire end, and the stationary contact bar of vacuum interrupter fixedly is electrically connected with last input terminal.
The utility model not only compact conformation, volume is little, in light weight, and possess do not have the no gas of oil, be beneficial to environmental protection, the danger of no combustion explosion and a deciliter action accurately put in place, and be safe and reliable to operation, the characteristics that maintenance workload is few.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view;
