Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of insulating protective cover, and it is compounded to form tolerant cavity by multilayer rubber screen layer, vacuum interrupter can carry out shielding protection effectively, and processing cost is low.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of insulating protective cover, including the housing with tolerant cavity, which is provided with opening, and is hermetically connected with the shell to close the upper cover of opening, if housing is composited by dried layer screen layer；Housing bottom bears the first boss and the second boss to extension, and the first boss is provided with perpendicular extension；Also including the first electrode and the second electrode, what the first electrode sealed is placed in extension, and what the second electrode sealed is placed in the second boss, and the two ends of first and second electrode are respectively communicated with extraneous and tolerant cavity.
As the further improved procedure of such scheme, screen layer is rubber.
As the further improved procedure of such scheme, the end face of opening is provided with seal groove, and seal washer adaptive therewith, and what detachable upper cover unloaded is fixed on end face and compresses seal washer.
As the further improved procedure of such scheme, housing is provided with observation window.
As the further improved procedure of such scheme, case inside wall is provided with the projection of some one-tenth certain intervals.
As the further improved procedure of such scheme, case inside wall is provided with locating slot.
As the further improved procedure of such scheme, outside first and second electrode, it is coated with housing.
As the further improved procedure of such scheme, the first boss is provided with the first installing hole, and for closing the plug of installing hole.
As the further improved procedure of such scheme, the second boss is provided with some second installing holes.
The invention has the beneficial effects as follows:
The receiving vacuum interrupter that the present invention can fully seal, the deformation of vacuum interrupter when rubber screen layer can compensate high temperature automatically, thus decrease its requirement to vacuum sealing, eliminate the technological process of surface spraying simultaneously, reduce cost.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the sectional view of one embodiment of the invention；
Fig. 2 be in Fig. 1 along A to sectional view；
Fig. 3 is the top view of one embodiment of the invention.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is clearly and completely described, to be completely understood by the purpose of the present invention, scheme and effect.It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
It should be noted that if no special instructions, when a certain feature is referred to as " fixing ", " connection " in another feature, and it can directly be fixed, be connected in another feature, it is also possible to indirectly fixes, be connected in another feature.Additionally, the upper and lower, left and right etc. used in the present invention describe and are only for the mutual alignment relation of each ingredient of the present invention in accompanying drawing.
Additionally, unless otherwise defined, all of technology used herein is identical with the implication that scientific terminology is generally understood that with those skilled in the art.Term the most used in the description is intended merely to describe specific embodiment rather than in order to limit the present invention.Term as used herein " and/or " include that the arbitrary of one or more relevant Listed Items combines.
With reference to Fig. 1, Fig. 2 and Fig. 3, show one embodiment of the present of invention, including housing 10, it uses the method for rubber co-extrusion to be composited, in order to reach the purpose of shielding, preferably rubber layer is divided into three layers, it is specially top layer 11, intermediate layer 12 and nexine 13, wherein, top layer 11 acts primarily as the effect of shielding, intermediate layer 12 is as the major part of housing 10, thickness is much larger than other two-layer, effectively high voltage in housing can be insulated, and nexine 13 directly contacts with vacuum interrupter, voltage can be carried out drain dividing potential drop, avoid the punch-through that local high voltage causes.
Being provided with tolerant cavity 101 and opening 102 in housing 10, unshowned vacuum interrupter is placed in cavity 101, and is contacted with extraneous by unshowned upper cover obstruct cavity.Preferably, in order to preferably realize sealing effectiveness, the end face at opening 102 is provided with seal groove, and the seal washer adaptive with seal groove, when upper cover is fixed on housing, compresses sealing ring and completes to seal.
Be provided with some projections 103 kept at a certain distance away in the medial wall of cavity 101, it can increase creep age distance, strengthens the dielectric strength of nexine 13.
Also including some locating slots 104 being vertically arranged, it can guarantee that vacuum interrupter is inserted in cavity 101 accurately.
In order to the situation in Real Time Observation cavity 101, it is carved with observation window 105 on the housing 10.
The bottom of housing 10 is raw to extension, forms the first boss 106 and the first boss 107, similar, first and second boss is also hollow, and connects with cavity 101, and wherein the first boss 106 is provided with perpendicular extension 1060.
Also including the first electrode 20 and the second electrode 30, it is respectively placed in extension 1060 and the second boss 107, and one end connects the external world, and the other end contacts with the vacuum interrupter in cavity 101.
In order to prevent the phenomenon that electric leakage occurs between electrode and its mounting structure, outside electrode, it is coated with housing 40, so, only could realize electrical contact at the two ends of electrode, effectively reduce the probability of electric leakage.
The bottom of the first boss 106 is provided with the first installing hole 1061, and vacuum interrupter can be fixed on housing by securing member by the through hole on the first electrode 20, similar, the second boss 107 also is provided with the second some installing holes 1070.
Because the first electrode is provided with through hole, can destroy the integral sealing environment of protective cover, so being additionally provided with seal plug 108, it can seal described first installing hole 1061 after regular worker completes.
The receiving vacuum interrupter that the present invention can fully seal, the deformation of vacuum interrupter when rubber screen layer can compensate high temperature automatically, thus decrease its requirement to vacuum sealing, eliminate the technological process of surface spraying simultaneously, reduce cost.
It is above the preferably enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art it may also be made that all equivalent variations or replacement on the premise of spirit of the present invention, and deformation or the replacement of these equivalents are all contained in the application claim limited range.
