Description
Technical field
The present invention relates to a kind of high-voltage switch gear divide-shut brake drive unit, particularly a kind of high-voltage switch gear vacuum insulation operation pipe.
Background technology
Existing high-voltage switch gear between vacuum switch tube and operating mechanism, transmit breaking-closing operating action and the insulated tension pole of an insulating effect is still traditional air insulation club shaped structure, there is following major defect in manufacture with in running in it: one is that size is large, the insulated tension pole length of such as vacuum circuit breaker for railway electrification is approximately 475mm, is the twice of vacuum switch length of tube.Two is greatly affected by environment, and insulating reliability is low, and rate of failure is high.
Summary of the invention
The object of this invention is to provide the high-voltage switch gear vacuum insulation operation pipe that a kind of size is little, insulating reliability is high.
Technical scheme of the present invention is, a kind of high-voltage switch gear vacuum insulation operation pipe, comprise porcelain shell, upper end cover and bottom end cover, upper moveable rod and lower lever, upper bellows and lower bellows, it is characterized in that: the T-shaped structure that described upper moveable rod and lower lever are made up of stainless steel, the small end of this upper moveable rod and lower lever is provided with internal thread or external screw thread, the blind hole that the large end of this upper moveable rod and lower lever is provided with the even pressure ring of ring-type and closes with porcelain knob diameter compatible, described porcelain shell and porcelain knob are made up of high strength china, the two ends of this porcelain shell and porcelain knob are all through metalized, upper end cover, upper moveable rod, between one end of upper bellows and porcelain shell, and bottom end cover, lower lever, brazing is between lower bellows and the other end of porcelain shell, the two ends of porcelain knob respectively and be brazing between the blind hole of upper moveable rod and lower lever.
The present invention compared with prior art, has compact conformation, and insulating reliability height waits remarkable advantage.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention at gate-dividing state.
Fig. 2 is the schematic diagram of the present invention in "on" position.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, more detailed description is done to the present invention.
The present invention adopts vacuum technique and the technique of existing vacuum switch tube maturation, have devised novel vacuum insulation operation pipe.With vacuum switch tube unlike, because upper and lower lever of the present invention is play together, set up the upper bellows of an airtight effect, because lower lever is uncharged, so be provided with the porcelain knob of insulating effect up and down between lever for this reason.
The present invention includes porcelain shell 6, up and down end cap 2, upper moveable rod 7, lower lever 1, up and down bellows 3 and porcelain knob 4.Upper and lower lever is that T-shaped structure is made up of stainless steel, and its small end is provided with internal thread or external screw thread, holds greatly the blind hole being provided with the even pressure ring 5 of ring-type and closing with porcelain knob diameter compatible.Porcelain shell and porcelain knob are made up of high strength china, and its two ends all can be welded through metalized.Upper end cover, upper moveable rod, between upper bellows and one end of porcelain shell, and bottom end cover, lower lever, between lower bellows and the other end of porcelain shell, be brazing, after soldering, form vacuum tank.Also be brazing between the two ends of porcelain knob and the blind hole of upper and lower lever.
Porcelain knob subjects and transmits breaking-closing operating action and High-Voltage Insulation function.The screw thread of upper and lower lever small end is connected with vacuum switch tube or operating mechanism respectively, and the even pressure ring of ring-type at its large end margin place can reduce the electric field strength at porcelain knob two ends.Adopt welding bellows, than shaping bellows, there is higher mechanical endurance and decrement.
The present invention and vacuum switch tube are after completing and being connected, and being molded as one of available epoxy mucilage binding pole, forms volume compact, the reliable novel high-pressure switch of insulation property, great popularization.
