Abstract
The utility model provides a high-voltage vacuum circuit breaker, belonging to the technical field of a high-voltage or large-current switch with an arc extinguishing or arc preventing device. Particularly, the utility model relates to the high-voltage vacuum circuit breaker. The utility model provides the high-voltage vacuum circuit breaker with a good insulating property and a small volume. The high-voltage vacuum circuit breaker provided by the utility mode comprises an insulating cylinder; an upper bracket, a vacuum arc extinguishing chamber and a lower bracket are arranged in the insulating cylinder; the upper bracket is connected with an upper wire outlet base; and the lower bracket is connected with a lower wire outlet base. According to the structural main points, an insulating material is filled among the upper bracket, the vacuum arc extinguishing chamber and the lower bracket in the insulating cylinder.
Description
Technical field
the utility model belongs to high pressure or the high-current switch technical field that has arc extinguishing or flash guard, relates in particular to a kind of high-pressure vacuum breaker.
Background technology
are present, and VS1 type circuit breaker is advanced high-pressure vacuum breaker.Its noise is little, requires low to service condition; It adopts the compound inslation mode, is about to the vacuum interrupter protection in the epoxy resins insulation tube.But in insulating cylinder, partly do not wrap electrification in high voltage fully, therefore have following weak point: the inside can receive the influence of dust, humidity, condensation, small worm etc. in (1) insulating cylinder.For reducing this influence, require the shell of vacuum interrupter that enough length is arranged, do like this, influenced the miniaturization of vacuum interrupter.
(2) only use four screws fastening because vacuum interrupter is to be lifted in the insulating cylinder, and less stable is easy in the action produce spring, influences the reliability of product quality.
(3) are collided with in assembling process easily, make vacuum interrupter damaged.
Summary of the invention
the utility model is exactly to the problems referred to above, and a kind of good insulation preformance, high-pressure vacuum breaker that volume is little are provided.
are for realizing above-mentioned purpose; The utility model adopts following technical scheme, and the utility model comprises insulating cylinder, is provided with upper bracket, vacuum interrupter, lower carriage in the insulating cylinder; Upper bracket links to each other with last outlet seat, and lower carriage links to each other with following outlet seat; In the said insulating cylinder of its structural feature, be filled with Insulating Materials between upper bracket, vacuum interrupter, the lower carriage.
as a kind of preferred version, the said Insulating Materials of the utility model adopts epoxy resin.
the utility model beneficial effect: (1) reliability is high.The utility model is compared with existing assembly type circuit breaker, and the parts of pole, conductor faying surface, connection significantly reduce with the quantity of securing member, have simplified the assembling link of major loop, has improved the reliability that the galvanic circle connects.
(2) good insulation preformance.The utility model upper bracket, vacuum interrupter, lower carriage link into an integrated entity through the Insulating Materials cast; Do not have the space between them, anti-environment is filthy, the condensation ability is strong.
(3) structure is firmer.Insulating Materials can provide protection more fully for vacuum interrupter, makes it in assembling or transportation, avoid accidental mechanical and collides.
(4) volume is little.The utility model adopts Insulating Materials as dielectric, and spaced apart can be dwindled, and has reduced the switch cubicle volume of vacuum circuit-breaker and adapted thereof.
(5) are non-maintaining.The whole pole of the utility model is poured into global facility through Insulating Materials, and vacuum interrupter has obtained sufficient protection, and vacuum interrupter non-maintaining is the non-maintaining condition that provides of circuit breaker.
(6) more environmental protection.The utility model pole type circuit breaker can replace FS6 gas as external insulation parts, environmental protection more to a certain extent.
Description of drawings
further specify the utility model below in conjunction with accompanying drawing and embodiment.The utility model protection range not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
During schemed
, 1 was that Insulating Materials, 2 is that vacuum interrupter, 3 is that insulating cylinder, 4 is that upper bracket, 5 is that last outlet seat, 6 is an outlet seat under lower carriage, 7 is.
Embodiment
are as shown in the figure, and the utility model comprises insulating cylinder 3, are provided with upper bracket 4, vacuum interrupter 2, lower carriage 6 in the insulating cylinder 3, and upper bracket 4 links to each other with last outlet seat 5, and lower carriage 6 links to each other with following outlet seat 7; In the said insulating cylinder 3, be filled with Insulating Materials 1 between upper bracket 4, vacuum interrupter 2, the lower carriage 6.
said Insulating Materials 1 adopts epoxy resin.The dielectric strength of epoxy resin is 5～6 times of air; After vacuum interrupter 2 is embedded into the epoxy resin solid material; The external environment of pole is reduced the influence of vacuum interrupter 2 significantly; Its external insulation ability can dust, moisture, toy, condensation and filthy influence, satisfies the filthy regional creepage requirement of secondary of GB/DL standard code fully.
The method that
the utility model seals cast admittedly can adopt APG automatic pressure gelation process (The Automatic Pressure Gelation); This technology is generally used in developed country by the exploitation of Switzerland vapour Bagong department at present.
casting material is under ambient pressure, to inject mould through running channel, and temperature is low during the material mixing treatment, and when solidifying, mold temperature is higher, and curing rate is fast, is generally tens minutes to dozens of minutes.With vacuum interrupter 2 and upper bracket 4, lower carriage 6, go up outlet seat 5, relevant galvanic circles such as outlet seat 7, conductive strips, conductive clip are embedded in the easy cured solid insulating material of this type of epoxy resin simultaneously down; Form pole, make whole galvanic circle and strutting piece become a global facility.In the gel process, keep injection pressure constantly to injecting virgin material in the die cavity, the defective so that compensation causes because of cure shrinkage reduces internal stress; Like this, part accuracy is high, and surface quality is good, and curing rate is fast.
it is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection range of the utility model.
Claims (2)
