Description
Technical field
The utility model relates to a kind of electrical device, especially a kind of protection box of power equipment, particularly says it is that a kind of electrical verification ground connection stays remaining guarded by location box.
Background technology
At present, the human casualty accident that in transformer station, pollution flashover, condensation flashover, icing tripping operation, toy short circuit, naked busbar cause happens occasionally.For this reason, transformer station has widely used material contracting with heat and has carried out insulating protection to outdoor bus, transformer first and second leading-out terminal, significantly decreases the generation of such accident, improves the reliability of electric power system.But, because busbar before and after bus and switch needs to carry out electrical verification ground connection after power failure, therefore, need before and after the main transformer busbar of ABC three-phase carrying out insulation and switch on busbar, cut the mouth of about 5 centimeters, for staying the electrical verification of remaining busbar electrified body and earthing position, so that electrical verification is earthy when overhauling.Although, construction technique has also been done relative against short-circuit measure, as the position of cutting insulation busbar A, B, C three-phase is adopted triangular arrangement, increase the distance of the exposed electrified body of three-phase, extend the distance between charged part, but often touched by toy and cause short circuit, bring serious loss and impact to work, agricultural and household electricity.Therefore, current urgent need design is a kind of can effectively to the device that electrical verification ground connection stays remaining position to protect.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of electrical verification ground connection to stay remaining guarded by location box, both available protecting electric power system can avoid occurring the accidents such as short circuit, and can facilitate again the operations such as the electrical verification of staff.
The technical solution of the utility model is:
A kind of electrical verification ground connection stays remaining guarded by location box, and comprise box body and capping, described box body is U-shaped structure, and capping covers and forms enclosed construction at box opening place and box body; Described box body is connected with capping is detachable.
Further, described box body is provided with locking device.
Further, described locking device comprises anti-drop sheet, screw and shifting disc, and described anti-drop sheet is arranged on shifting disc by screw.
Further, described shifting disc arranges polygonal nut.
Further, stir described in and offer through hole.
Further, the layer bar being with through hole or screw thread is provided with between described box body and closure contacts face.
Further, described inboard wall of cartridge surrounding arranges drag reduction bar.
The beneficial effects of the utility model:
The utility model is reasonable in design, and structure is simple, easy for installation, the remaining mouth that stays on busbar can be encased completely, prevents toy from touching and being short-circuited., can remove easily again, easy access operates, and has positive effect to the safety in production of power industry meanwhile.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
Fig. 2 is the left view of embodiment of the present utility model.
In figure: 1-screw a; 2-shifting disc; The polygonal nut of 3-; 4-screw b; 5-anti-drop sheet; 6-box body; 7-drag reduction bar; 8-layer bar; 9-capping; 10-through hole; 11-busbar; 12-insulator; 13-electrical verification ground connection stays remaining mouth.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As depicted in figs. 1 and 2, be an embodiment of the present utility model, comprise box body 6 and capping 9, described box body is U-shaped, and the electrical verification ground connection be sleeved on busbar 11 stays Yu Kouchu.On described busbar 11, except electrical verification ground connection stays remaining mouth 13, surface is equipped with insulator 12.The length of box body 6 is greater than the width that electrical verification ground connection stays remaining mouth, and is provided with capping 9 at box body 6 opening part, can form four face closures with box body 6.For the ease of handling, box body 6 is connected for detachable with capping 9, and such as employing runs through screw a1 and connects.Described box body 6 is provided with locking device, as required box body can be fixed tightly in and stays on remaining mouth busbar.This locking device comprises anti-drop sheet 5 and shifting disc 2, and wherein, anti-drop sheet 5 is arranged on shifting disc 2 by screw b4, and on shifting disc 2, arrange through hole 10 and polygonal nut 3.When rotating shifting disc 2, screw b can be driven to rotate, and then promotion anti-drop sheet 5 move in box body, until prop up busbar 11, then tightens polygonal nut 3, just box body 6 can be fixed.When needs electrical verification, unclamp polygonal nut 3, reverse rotation shifting disc 2, make anti-drop sheet 5 depart from busbar, box body 6 just can be made to loosen, so that mobile.
As shown in Figure 2, consider that protected busbar 11 may be multilayer, between box body 6 and capping 9 contact-making surface, be provided with the layer bar 8 being with through hole or screw thread, make it corresponding with each layer busbar 11.Because the present embodiment adopts two ends move mode, the resistance produced during in order to reduce mobile, box body 6 inwall is provided with some drag reduction bars 7, more smooth when moving it.
Above-described embodiment is the principle of illustrative the application and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all under the spirit and category of the application, can modify above-described embodiment or changes.Therefore, have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the application discloses, must be contained by the claim of the application.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
