Abstract
The breaker comprises the insulation part, the vacuum arc extinguish chamber, external insulation, internal insulation, the support part, the insulation pull rod, the spring device and the driving system. The upside external insulation is silicone rubber solid insulation. The upside internal insulation is the insulation with fluid silicone rubber being filled between the extinguish chamber and the glass fiber winding barrel. The underpart is air insulated. There are multiple sulfurated inner umbrella skirts and outer umbrella skirts inside and outside glass fiber winding barrel. The insulation pull rod with the lead and lift bar of the glass fiber being as framework is installed inside glass fiber winding barrel. There are sulfurated silicone rubber and umbrella skirts in outside also. The lower part of the pull rod is connected to the driving system. Without using sulfur hexafluoride, the invention has no pollution, suitable for use outdoor as high voltage vacuum breaker.
Description
Technical field:
The present invention relates to the outdoor high-voltage vacuum breaker technical field, exactly it is that a kind of no porcelain is made external insulation, and insulating oil is not filled in interior insulation, does not fill the outdoor high-voltage vacuum breaker of insulating gas.
Background technology:
Vacuum circuit-breaker and sulfur hexafluoride breaker in the following operation of power networks of 35kV in electric power system at present, and oil-minimum breaker just is eliminated out of service.The overwhelming majority is a sulfur hexafluoride breaker in the electrical network more than 72.5kV, also has to reach few oil-minimum breaker in operation.Sulfur hexafluoride gas mainly is the effect of playing arc extinguishing and interior insulation in circuit breaker, and external insulation is all made with ceramic material.Sulfur hexafluoride gas is a kind of gas harmful to atmosphere, and sulfur hexafluoride gas a large amount of uses in circuit breaker will influence the greenhouse effect in the whole world.Therefore 1997 " UNFCCC (United Nations Framework Convention on Climate Change) Kyodo Protocol protocol " arranges; The sulfur hexafluoride gas as arc extinguishing and dielectric will limit use in the high voltage switchgear to being applied to.
Because environmental issue is to cause international concern, therefore developing environment-friendly products is present urgent task.Japan, Germany are going before aspect the exploitation vacuum circuit-breaker, and especially Japan is in the existing nearly 10 years operating experience of 126kV electric pressure, and he is developing the vacuum circuit-breaker of 252kV.But the circuit breaker of Japan is an arc-extinguishing medium adopts vacuum, and insulation is still done insulation with sulfur hexafluoride gas in it, does not accomplish real environment-friendly products.
Summary of the invention:
The purpose of this invention is to provide a kind of no porcelain and make external insulation, insulating oil is not filled in interior insulation, do not fill the outdoor high-voltage vacuum breaker of insulating gas, it comprises insulated part, vacuum interrupter, external insulation, interior insulation, support part, insulated tension pole, frame, spring mechanism, mounting column, drive system, it is characterized in that: the top external insulation is the silicon rubber solid insulation, insulation is to charge into a kind of fluid silicone rubber (2) insulation between arc control device (1) and glass fiber winding cylinder (3) in the top, the bottom is an air insulation, and the inside and outside sulfuration of glass fiber winding cylinder (7) of bottom has a plurality of interior full skirts (6) and external shed (8).The outside sulphurated siliastic full skirt of insulated part skeleton glass fiber winding cylinder (3) (4).The insulated tension pole (5) that the glass fiber leading-drawing rod is done skeleton is installed in the glass fiber winding cylinder (7), and its outside is the once silicon rubber of sulfidization molding and full skirt also, and insulated tension pole (5) below is connected with drive system (12).Operating mechanism adopts the spring for accumulating energy linkage.
Advantage of the present invention is:
1, without any pollution, is real environment-friendly products because the present invention does not use sulfur hexafluoride gas to do insulation, thereby to people and surrounding environment, and just in case fault can not injure surrounding devices and personal safety.
2, simple in structure, easy for installation, maintenance is few, the overhaul of need not disintegrating.
3, because exposed parts is a silicon rubber, and external force resistance destruction aspect is better than porcelain, the moisture-resistant pollution flashover ability of silicon rubber is higher than porcelain.
4, adopt spring mechanism, maintenance is few, the reliability height.
5, structure of the present invention can expand to 40.5kV, 72.5kV, 126kV, 252kV, and its spreading range is wider cut-offfing aspect the capacity, can satisfy the needs of electric power system fully.

Fig. 2 is the right view of Fig. 1.
Among the figure 1 be vacuum interrupter, 2 for fluid silicone rubber, 3 for arc control device glass fiber winding cylinder, 4 for the silicon rubber full skirt, 5 for insulated tension pole, 6 for interior full skirt, 7 for supporting pillar glass fiber system practice tube, 8 for external shed, 9 for frame, 10 spring mechanisms, 11 for mounting column, 12 be drive system.
Embodiment:
Embodiment:
The epoxy fibreglass winding cylinder skeleton that epoxy resin and glass fiber are made is adopted in insulation among the present invention, external insulation adopts silicon rubber to do full skirt, its creep distance and hydrophobicity are higher than porcelain under equal distance condition, wet pollution flashover is higher than porcelain, arc control device partly are to do skeleton by the epoxy fibreglass winding cylinder, outside sulphurated siliastic full skirt, be full of a kind of fluid silicone rubber between winding cylinder and the arc control device as insulating in the top, the lower support part is also done skeleton with the epoxy fibreglass winding cylinder, inside and outside all sulfuration the silicon rubber full skirt arranged, wherein inside and outside have a plurality of silicon rubber full skirts, and the upper and lower can be linked together by flange.Frame, spring mechanism, mounting column and drive system are prior art, and general circuit breaker factory all can produce.
When circuit breaker during in the separating brake position, feed motion is as follows: behind the spring mechanism energy storage, receiving the order back energy storage that closes a floodgate and discharging, mechanism's output shaft moves upward.Make girt in the drive system to left movement by connecting lever, girt drives vertical guide stem by connecting lever and moves upward, and the moving contact that promote insulated tension pole, drives vacuum interrupter moves upward, with the upper static contact closure of vacuum interrupter.And make the compression of contact spring produce very big contact thrust.Simultaneously girt draws back sluice separating spring to the separating brake storing energy when left movement in the making process, close a floodgate end in-house inside and outside buckle with lock for circuit breaker at closing position, when circuit breaker during at closing position, the action of separating brake position is as follows:
After receiving order, the inside and outside buckle of spring mechanism discharges, and the trunnion axis of drive system is under the effect of tripping spring and contact pressure spring, and moving contact and insulated tension pole move downward, and girt moves to the right.Dynamic/static contact is separated into the position that buffer limits, and closes a floodgate to end.
