Abstract
The invention relates to a mutual inductor and an adsorber cover plate thereof. An explosion-proof channel is arranged on the adsorber cover plate; an explosion-proof cover is fixed on the cover plate, and accordingly, the explosion-proof structure of the mutual inductor is moved upwards to the side wall of the shell of the mutual inductor, so that the explosion-proof cover can be mounted when the mutual inductor is upright, and the mounting difficulty of the explosion-proof cover is reduced; furthermore, the explosion-proof channel does not need to be arranged on the base plate of the mutual inductor and the explosion-proof cover does not need to be fixed and packaged, so that the structure of the base plate of the mutual inductor is simplified; and the explosion-proof channel is less difficult to process and is lower in cost when arranged on the adsorber cover plate.
Description
Technical field
The present invention relates to converting equipment technical field, particularly relate to a kind of instrument transformer, also relate to the adsorbent frame that this instrument transformer uses simultaneously.
Background technology
220kV GIS(fully closed combined electric unit) effect of absorber of supporting voltage transformer is by the moisture in its inner fixing encapsulation adsorbent instrument transformer inner chamber; and the effect of the Explosion-proof cap of adapted is inside cavity pressure increase when preventing voltage transformer abnormal on voltage transformer; the namely Explosion-proof cap cracking release pressure when pressure reaches certain numerical value, protection instrument transformer.At present, the absorber cover plate 3 of instrument transformer (as shown in Figure 1) is fixedly encapsulated on opening that housing 1 sidewall is offered, and Explosion-proof cap 5 fixes the outer end of the explosion-proof passage 4 that encapsulation is offered on a base plate 2, but when erectting on the ground at instrument transformer, distance between the bottom of instrument transformer and bottom surface is less, therefore after other parts of instrument transformer must having been assembled, instrument transformer traverse or inversion just can be carried out the installation of Explosion-proof cap 5, thus add the installation difficulty of Explosion-proof cap 5, extend the assembly period of whole instrument transformer, reduce production efficiency.
Summary of the invention
The present invention proposes a kind of instrument transformer, additionally provide the absorber cover plate that this instrument transformer uses simultaneously, the Explosion-proof cap being intended to solve instrument transformer in prior art installs the problem of difficulty.
The technical scheme of instrument transformer of the present invention is as follows:
A kind of instrument transformer, comprise the absorber cover plate on the sidewall opening being fixedly encapsulated in instrument transformer housing, described absorber cover plate offers the explosion-proof passage of the inner space by described sidewall opening and instrument transformer, described explosion-proof passage have be in absorber cover plate away from the opening on the side plate face of described instrument transformer housing, described absorber cover plate is fixed with the Explosion-proof cap for opening described in shutoff.
The side away from described instrument transformer housing of described absorber cover plate is provided with for the removable fixed structure being fixedly connected with Explosion-proof cap, described fixed structure comprises the screwed hole that described absorber cover plate is offered, described Explosion-proof cap offers the unthreaded hole corresponding with described screwed hole, be equipped with attachment screw in described unthreaded hole, described attachment screw revolves be located at described screwed hole from the part that passes of described unthreaded hole.
The technical scheme of the absorber cover plate that instrument transformer of the present invention uses is as follows:
The absorber cover plate that a kind of instrument transformer uses, described absorber cover plate offers the explosion-proof passage of the inner space by described sidewall opening and instrument transformer, described explosion-proof passage have be in absorber cover plate away from the opening on the side plate face of described instrument transformer housing, described absorber cover plate is fixed with the Explosion-proof cap for opening described in shutoff.
The side away from described instrument transformer housing of described absorber cover plate is provided with for the removable fixed structure being fixedly connected with Explosion-proof cap, described fixed structure comprises the screwed hole that described absorber cover plate is offered, described Explosion-proof cap offers the unthreaded hole corresponding with described screwed hole, be equipped with attachment screw in described unthreaded hole, described attachment screw revolves be located at described screwed hole from the part that passes of described unthreaded hole.
Explosion-proof passage is opened on absorber cover plate by the present invention, and Explosion-proof cap is fixed on the cover board, thus make the blast resistance construction of instrument transformer above be moved on the sidewall of instrument transformer housing, make the installation can carrying out Explosion-proof cap when instrument transformer is upright, reduce the installation difficulty of Explosion-proof cap, and owing to no longer needing to offer explosion-proof passage on the base plate of instrument transformer, also fixing encapsulation Explosion-proof cap is no longer needed, thus simplify the structure of instrument transformer base plate, and by offering the difficulty of processing that explosion-proof passage reduces explosion-proof apparatus passage on absorber cover plate, cost-saving.
