Background technology
The effect of the supporting absorber with voltage transformer of 220kV GIS (fully closed combined electric unit) is through the moisture in its internal fixation encapsulation adsorbents adsorb instrument transformer inner chamber; And the effect of the Explosion-proof cap of adapted is that inside cavity pressure increases when preventing that voltage transformer is unusual on the voltage transformer; Just Explosion-proof cap cracking release pressure when pressure reaches certain numerical value is protected instrument transformer.At present; Absorber cover plate 3 fixed sealing of instrument transformer (as shown in Figure 1) are contained on the opening of offering on housing 1 sidewall, and Explosion-proof cap 5 fixed sealing are contained in the outer end of the explosion-proof passage of offering on the base plate 24, yet when erectting on the ground at instrument transformer; The bottom and the distance between the bottom surface of instrument transformer are less; Therefore after must other part assemblings of instrument transformer being accomplished, instrument transformer traverse or inversion just can be carried out the installation of Explosion-proof cap 5, thereby increased the installation difficulty of Explosion-proof cap 5; Prolong the assembly period of whole instrument transformer, reduced production efficiency.
Summary of the invention
The present invention proposes a kind of instrument transformer, the absorber cover plate of this instrument transformer use also is provided simultaneously, be intended to solve the problem of the Explosion-proof cap difficult installation of instrument transformer in the prior art.
The technical scheme of instrument transformer of the present invention is following:
A kind of instrument transformer; Comprise that fixed sealing is contained in the absorber cover plate on the sidewall opening of instrument transformer housing; Offer the explosion-proof passage that is communicated with the inner chamber of instrument transformer through said sidewall opening on the said absorber cover plate; Said explosion-proof passage have be in the absorber cover plate away from the opening on the side plate face of said instrument transformer housing, be fixed with the Explosion-proof cap that is used for the said opening of shutoff on the said absorber cover plate.
Side away from said instrument transformer housing of said absorber cover plate is provided with the fixed structure that is used for removable fixed connection Explosion-proof cap; Said fixed structure comprises the screwed hole of offering on the said absorber cover plate; Offer the unthreaded hole corresponding on the said Explosion-proof cap with said screwed hole; Be equipped with attachment screw in the said unthreaded hole, said attachment screw revolves and is located at the said screwed hole from the part that passes of said unthreaded hole.
The technical scheme of the absorber cover plate that instrument transformer of the present invention uses is following:
The absorber cover plate that a kind of instrument transformer uses; Offer the explosion-proof passage that is communicated with the inner chamber of instrument transformer through said sidewall opening on the said absorber cover plate; Said explosion-proof passage have be in the absorber cover plate away from the opening on the side plate face of said instrument transformer housing, be fixed with the Explosion-proof cap that is used for the said opening of shutoff on the said absorber cover plate.
Side away from said instrument transformer housing of said absorber cover plate is provided with the fixed structure that is used for removable fixed connection Explosion-proof cap; Said fixed structure comprises the screwed hole of offering on the said absorber cover plate; Offer the unthreaded hole corresponding on the said Explosion-proof cap with said screwed hole; Be equipped with attachment screw in the said unthreaded hole, said attachment screw revolves and is located at the said screwed hole from the part that passes of said unthreaded hole.
The present invention is opened in explosion-proof passage on the absorber cover plate; And Explosion-proof cap is fixing on the cover board, thereby make instrument transformer blast resistance construction by on move on the sidewall of instrument transformer housing, make and under the upright situation of instrument transformer, can carry out the installation of Explosion-proof cap; Reduced the installation difficulty of Explosion-proof cap; And owing on the base plate of instrument transformer, no longer need offer explosion-proof passage, also no longer fixing encapsulation Explosion-proof cap, thus simplified the structure of instrument transformer base plate; And, practice thrift cost through on the absorber cover plate, offering the difficulty of processing that explosion-proof passage has reduced the explosion-proof apparatus passage.

Embodiment
The embodiment of instrument transformer of the present invention: as shown in Figures 2 and 3; Base plate 12, the fixed sealing that this instrument transformer comprises instrument transformer housing 11, be in instrument transformer housing 11 bottoms be contained in absorber cover plate 13 on the opening of offering on instrument transformer housing 11 sidewalls, be fixed on the absorber framework 14 on the medial surface of absorber cover plate 13; The outside of said absorber cover plate 13 is fixed with Explosion-proof cap 17; Offer the explosion-proof passage 15 that is communicated with the inner chamber of instrument transformer housing 11 through absorber framework 14 on the absorber cover plate; Explosion-proof passage 15 has the opening that is on absorber cover plate 13 lateral surfaces, and absorber cover plate 13 is provided with and is used for the Explosion-proof cap 17 removable fixed structures 16 that are fixed on the absorber cover plate 13, and this fixed structure 16 is made up of the screwed hole of offering on the absorber cover plate 13; On Explosion-proof cap 17, offer the unthreaded hole corresponding with said screwed hole; Be equipped with attachment screw 16-1 in the unthreaded hole, attachment screw 16-1 passes from unthreaded hole, passes partly to revolve to be located in the said screwed hole.
The present invention is opened in explosion-proof passage 15 on the absorber cover plate 13; And Explosion-proof cap 17 is fixing on the cover board, thereby make instrument transformer blast resistance construction by on move on the sidewall of instrument transformer housing 11, make and under the upright situation of instrument transformer, can carry out the installation of Explosion-proof cap 17; Reduced the installation difficulty of Explosion-proof cap 17; And owing on the base plate 12 of instrument transformer, no longer need offer explosion-proof passage 15, also no longer need fix encapsulation Explosion-proof cap 17, thereby simplify the structure of instrument transformer base plate 12; And, practice thrift cost through on absorber cover plate 13, offering the difficulty of processing that explosion-proof passage 15 has reduced the explosion-proof apparatus passage.In addition because the adsorbent of filling in the absorber framework 14 can play damping action to the gas that gets in the explosion-proof passage 15; Guaranteed the consistency of gas pressure in gas and instrument transformer housing 11 inner chambers in the explosion-proof passage 15; Thereby strengthened sealing effectiveness, reduced the impulsive force of the sudden change of gas pressure in instrument transformer housing 11 inner chambers Explosion-proof cap 17 to 17 pairs of explosion-proof passages 15 of Explosion-proof cap.
In the above-described embodiments; Explosion-proof cap is fixed on the absorber cover body outside face through fixed structure is removable; In other embodiments, Explosion-proof cap also can be weldingly fixed on the absorber cover body outside face, and corresponding fixed structure is the Welding Structure between Explosion-proof cap and the absorber lid.
The embodiment of absorber lid of the present invention: as shown in Figures 2 and 3, in the above-described embodiments, offer some clarification on, therefore repeat no more in the present embodiment about the concrete structure of absorber lid.
