Abstract
The utility model relates to a high-pressure permanent magnetism structure vacuum circuit breaker for a sealed station. Three lower insulation shells are fixed to the top of the pedestal through a bolt, and are fixed with insulation shells through the bolts and lower outlet terminals, the upper insulation shell is fixed with an upper inlet wire end cover through the blot, and a support bracket is fixed to the lower portion of the pedestal. The inner cavities formed by every lower insulation shell, upper insulation shell and upper inlet wire end cover are respectively fixed with a permanent magnetism structure, an insulation draft bar and a vacuum extinction chamber from the downside to the upside. One end of the power take-off shaft of the permanent-magnet structure is connected with the insulating draft bar, and the other end of the insulating draft bar is hinged on the movable bunter of the vacuum extinction chamber. The movable bunters are fixed to the lower outlet terminal through the soft connection, and the static bunter of the vacuum extinction chamber is fixed to the upper inlet wire terminal cover 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 station high-voltage permanent-magnetic mechanism vacuum circuit-breaker, is widely used in three-phase alternating current power transmission and transformation line deciliter normal duty, overload and short circuit current in 50Hz, 12kV～126kV transformer and distribution power station, and suitable frequent operation.
(2), background technology
At present, the outdoor vacuum circuit breaker of domestic transformer and distribution power station usefulness 10kV and 35kV, 110kV electric pressure adopts electromagnetic mechanism or spring energy-storage operating mechanism more, and invests outside the breaker body.Because its mechanism's complexity, middle transmission link is many, 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.35kV and 110kV outdoor switch mostly are inflation, oil-filled equipment, and failure rate is higher, and the maintaining workload is big, also is unfavorable for environmental protection.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of fixed sealing type station high-voltage permanent-magnetic mechanism vacuum circuit-breaker, and its compact conformation, volume are little, in light weight, and possess and do not have the no gas of oil, be beneficial to environmental protection and a deciliter action accurately puts in place, safe and reliable to operation, the advantage that maintenance workload is few.
The technical scheme in the invention for solving the technical problem is: the top of pedestal is by three following insulation crusts of bolt, three following insulation crusts are respectively by bolt, the fixing insulation crust of going up of lower wire end, last insulation crust is respectively by end of incoming cables lid on the bolt, the below fixed support of pedestal; Each down insulation crust, go up in the cavity of insulation crust and the lid formation of last end of incoming cables from bottom to up respectively fixedly permanent magnet mechanism, insulated tension pole, vacuum interrupter, one end of the power output shaft of permanent magnet mechanism connects insulated tension pole, the other end of insulated tension pole is hinged on the movable feeler lever of vacuum interrupter, movable feeler lever is fixed on by being flexible coupling on lower wire end, and the fixed contact of vacuum interrupter fixedly is electrically connected with last end of incoming cables lid.
The utility model is compared with circuit breaker oil-filled, inflation with present electromagnetism or spring mechanism vacuum circuit-breaker in usefulness, not only compact conformation, volume are little, in light weight, and possess and do not have the no gas of oil, are beneficial to environmental protection and a deciliter action accurately puts in place, safe and reliable to operation, maintenance workload characteristics seldom.
(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;
Fig. 2 is the utility model left view.
(5), embodiment
As shown in Figure 1, 2,2, three following insulation crusts 2 of three following insulation crusts are fixed respectively by bolt 16, the lower wire end 8 fixing insulation crusts 15 of going up by bolt 17 in the top of pedestal 1, and last insulation crust 15 is respectively by the bolt 14 fixing end of incoming cables lids 13 of going up.The below fixed support 19 of pedestal 1.Each down insulation crust 2, go up in the cavitys of insulation crust 15 and lid 13 formation of last end of incoming cables from bottom to up respectively fixedly permanent magnet mechanism 5, insulated tension pole 7, vacuum interrupter 11.The upper end of the power output shaft 6 of permanent magnet mechanism 5 connects insulated tension pole 7, and the upper end of insulated tension pole 7 is hinged on the movable feeler lever 10 of vacuum interrupter 11, and movable feeler lever 10 9 is fixed on lower wire end 8 by being flexible coupling.The fixed contact 12 of vacuum interrupter 11 fixedly is electrically connected with last end of incoming cables lid 13.The lower end of the power output shaft 6 of described permanent magnet mechanism 5 is stretched into pedestal 1 and is connected with manual emergency switching-off device 18, and a manual brake separating bar 4 and three divide-shut brake pointers 3 are arranged on the manual emergency switching-off device 18.
The material of described upper and lower insulation crust 15,2 is resin compounded silicon rubber or high-strength ceramic, and 9 the material of being flexible coupling is silver-plated red copper foil.
