Description
Technical field
The utility model relates to high-tension distribution equipment technical field, particularly a kind of novel vacuum switch unit.
Background technology
Current vacuum switch is most, and for breaker vacuum switch element is an independently unit, isolating switch is an independently unit, and conducting loop structure complexity of two cell formations, causes non-uniform electric, works long hours and can produce much harm.And be difficult to realize two air-tightness between unit, can be subject to as the impact of the external environment conditions such as steam, dust on the electric property of vacuum switch unit.
Utility model content
Technical problem to be solved in the utility model is to overcome the existing above-mentioned defect of prior art and a kind of vacuum switch unit is provided, this vacuum switch unit has breaker vacuum switch element and Disconnecting switch unit Highgrade integration, simple in structure, and Electric Field Distribution is even; Realized two unit and be all contained in the pole of an epoxy casting, hermetically-sealed construction can meet air-tightness standard.
Technical solution of the present utility model is as follows:
A vacuum switch unit, is characterized in that, comprises breaker vacuum switch element and tri-station isolating switch unit, and breaker vacuum switch element and tri-station isolating switch unit are assembled in the pole of an epoxy casting; Described breaker vacuum switch element pulls insulated tension pole assembling to drive vacuum interrupter deciliter by operating mechanism, and isolating switch vacuum switch unit, by operating mechanism pushing drawing rod, makes isolating switch be grounded, isolate, work.
In a preferred embodiment of the present utility model, in the external spray of described pole, there is semiconductor substance layer.
Advantage of the present utility model:
1) owing to having adopted, all galvanic circles of breaker vacuum switch element and tri-station isolating switch unit are all arranged in pole, have greatly optimized the Electric Field Distribution of galvanic circle.
2) because the design of this vacuum switch unit easily reaches hermetically sealed mode, design, can not produce harmful substance in the course of the work, and all parts reach all recyclable after useful life, greatly improve the feature of environmental protection of product, adapt to environmental protection demand.
3) because all major loop electrified bodies are all poured into a mould or are arranged in epoxy resin, can not be subject to as the impact of the external environment conditions such as steam, dust on the electric property of ring main unit.Reduced equipment maintenance, extended useful life.
4) because major loop electrified body is all inner at epoxy resin, and in epoxy resin external spray, there is semiconductor substance to likely producing the place of induced voltage, by this material, by induced voltage ground connection, even if people touches also and can not produce Danger Electric shock risk like this, improved the fail safe of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vacuum switch unit of the present utility model.
Fig. 2 is a kind of vacuum switch unit conducting loop structure schematic diagram of the present utility model.
In figure 1 is pole, the 2nd, insulated tension pole assembling, the 3rd, and isolating switch mechanism pull bar, the 4th, conductor, the 5th, is flexible coupling, the 6th, grounding contact, the 7th, isolation knife, the 8th, isolation knife pull bar, the 9th, isolation knife base, the 10th, the quiet end conductor of vacuum interrupter, the 11st, vacuum interrupter.
Embodiment
Contrast accompanying drawing, one end of the quiet end conductor 10 of vacuum interrupter and the quiet end of vacuum interrupter 11 in this vacuum switch unit link together.The moved end end face of vacuum interrupter 11 is placed and is flexible coupling 5, the end of thread of the insulated tension pole assembling 2 of actuating vacuum interrupter 11 actions is screwed in the screwed hole of moved end of vacuum interrupter 11, and compresses 5 the one end of being flexible coupling, and guarantees that conduction is reliable.5 the other end of being flexible coupling is connected with the conductor 4 in pole by screw.The other end of insulated tension pole assembling 2 is connected with breaker mechanism.When breaker mechanism moves, then drive insulated tension pole assembling 2 motions, then drive the moved end motion of vacuum interrupter 11, realize vacuum switch deciliter.When three position mechanism drives 3 action of isolating switch pull bar, then drive isolation knife 7 to rotate, the action that is grounded, isolates, works.
Pole 1 is the shaped piece with cavity being formed by poured with epoxy resin, the quiet end of vacuum interrupter 11 is connected by one end of the quiet end conductor 10 of screw and vacuum interrupter, is cast in epoxy resin together with the conductor of the quiet end conductor 10 of vacuum interrupter, vacuum interrupter 11 and isolation knife base 9.External spray at pole 1 has semiconductor substance layer.
Insulated tension pole assembling 2 is by nylon, two inserts cast to be formed, and by breaker mechanism, drives insulated tension pole 2 actions, realizes 11 deciliters actions of arc control device.
The quiet end conductor 10 of vacuum interrupter is special-shaped conductors, and the quiet end of one end and vacuum interrupter 11 is connected, and one end is a cutter head in addition, realizes the whole loop conducting when service position of three station disconnecting links.
Being constructed as follows of the galvanic circle of vacuum switch unit:
When vacuum switch, main conductive circuit by the conductor 4 in pole, be flexible coupling 5, vacuum interrupter 11, the quiet end conductor 10 of vacuum interrupter, isolation knife 7, grounding contact 6, isolation knife base 9 form.Position on Fig. 2 is that isolation knife is in earthing position.
When three position mechanism action, promote three station pull bars 3 to left movement, by Fig. 2, be rotated counterclockwise 43 while spending, drive isolation knife 7 rotations to depart from grounding contacts 6, between vacuum interrupter stationary contact end conductor 10 other end cutter heads and grounding contact 6, isolation knife is in isolated location;
When three position mechanism action, promote three stations and draw 6 continuation to left movement, be rotated counterclockwise 86 while spending, drive quiet end conductor 10 other end cutter heads engagements of isolation knife 7 rotations and vacuum interrupter, isolation knife 7 is in service position.
All electrified body major loops of the present utility model are all placed in pole 1, and Interface design easily reaches air-tightness standard, has avoided exposing of electrified body, have that volume is little, an environment-friendly type, the advantage such as function is integrated, reliability is high, non-maintaining, solid insulation.
