Abstract
The utility model relates to an inflatable shielding cap for testing partial discharge, which is technically characterized by comprising an inflatable air bag, an aluminum foil layer, an inflating nozzle and a binding tape, wherein the aluminum foil layer is adhered to the outer surface of the inflatable air bag, the inflating nozzle is arranged at the upper end of the inner side of the inflatable air bag, the binding tape is installed at two ends of the lower part of the inner side of the inflatable air bag, and the binding tape is used for being connected with a high-voltage wire connecting end of tested equipment. The inflatable shielding cap provided by the utility model is reasonable in design, adopts the elastic inflatable air bag, and covers the outer surface of the inflatable air bag by the aluminum foil layer with high elasticity. A function of shielding high-voltage signal interferences is realized by binding the inflatable shielding cap at the high-voltage wire connecting part of the tested equipment, thereby solving a problem that installation of the shielding cap wastes time and energy, and improving the test efficiency. The inflatable shielding cap provided by the utility model has the advantages of simple structure, small size, light weight, convenient carrying and the like.
Description
Technical field
The utility model belongs to discharge test technical field, and test shielding cap is put in especially a kind of inflatable office.
Background technology
Large scale electrical power unit as the partial discharge test such as transformer, mutual inductor test process in, play a game and put the undesired signal in test process for masking point discharge, suspended discharge etc., need to put and on testing high voltage connection terminal, shielding cap is installed and be shielded interference in office.Existing shielding cap adopts aluminium or copper material conventionally, and its volume and weight is larger.Carrying out in discharge test test process, shielding cap is installed wastes time and energy, and for taller and bigger testing apparatus, needs the shielding cap that lifting is larger, has increased the restriction of test setup time and test site.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, volume is little, test shielding cap is put in lightweight and portable inflatable office.
The utility model solves its technical matters and takes following technical scheme to realize:
Test shielding cap is put in one inflatable office, draw together air bag, aluminium foil layer, inflating nozzle and binding strap, described aluminium foil layer is mounted on the outside surface of air bag, described inflating nozzle is arranged on the upper end of air bag inner side, described binding strap is arranged on side-lower two ends in air bag, and this binding strap is for being connected with the high-voltage terminal of tested equipment.
And described air bag is made up of elastomeric material.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, it adopts telescopic air bag and covers the stronger aluminium foil layer of retractility at the outside surface of air bag, high-voltage connection place by its colligation at tested equipment, realize the function that shielding high-voltage signal disturbs, solve existing shielding cap the problem that shielding cap is wasted time and energy has been installed, improve testing efficiency, there is the advantages such as simple in structure, volume is little, quality is light, be easy to carry.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
Test shielding cap is put in one inflatable office, as shown in Figure 1, comprises air bag 3, aluminium foil layer 2, inflating nozzle 1 and binding strap 4.Described aluminium foil layer is mounted on the outside surface of air bag, and this aluminium foil layer has fold, thereby makes aluminium foil layer have good extensibility.Described air bag is made up of elastomeric material, after inflation, can expand, and after exhaust, can shrink.Described inflating nozzle is arranged on the upper end of air bag inner side, can be to inflation in air bag or from air bag to outside exhaust by this inflating nozzle.Described binding strap is arranged on side-lower two ends in air bag, uses binding strap to tie up to high-voltage connection place of tested equipment, plays the effect that shielding high-voltage signal disturbs.
At the utility model in use, can be according to the size of tested equipment high-pressure section, use inflator to inflate to air bag from inflating nozzle, after inflation, shielding cap is mushroom, after inflation, tie up to high-voltage connection place of tested equipment with binding strap, thereby realize the function that shielding high-voltage signal disturbs.
It is emphasized that; embodiment described in the utility model is illustrative; instead of determinate; therefore the utility model comprises and is not limited to the embodiment described in embodiment; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
