Abstract
The utility model discloses a tool for quickly short connecting a current terminal, which is provided with a current terminal connecting sheet (1); a plurality of screw mounting fork entries (4) are arranged on the current terminal connecting sheet (1); the screw mounting fork entries (4) are slot-shaped openings arranged on the lateral side of the current terminal connecting sheet (1); a connecting screw (2) is arranged on each screw mounting fork entry (4) and is fixed on the current terminal connecting sheet (1) by a screw cap (3). By adopting the technical scheme and aiming at the problem in high-voltage withstand voltage test, the tool is used for replacing iron wires, thereby greatly reducing the work load of testers, and improving the working efficiency and percent of pass of delivery inspection. The tool for quickly short connecting the current terminal is convenient to obtain materials, has simple method and convenient check, can reliably connect the current terminals, and reduce misoperation.
Description
Technical field
The utility model belongs to the technical field of electric power dispensing device, relates to the high pressure withstand voltage test technology of 10KV and above complete high-tension switch cabinet, and more particularly, the utility model relates to a kind of instrument of quick short circuit current terminal.
Background technology
At present, all need to do the high pressure withstand voltage test before complete high-tension switch cabinet dispatches from the factory, in withstand voltage test, its main bus bar is applied 4.2KV/9.5KV voltage.
For protection instrument transformer secondary side, usually the secondary line on the instrument transformer is done ground protection.Because its secondary line is through current terminal, so generally do before the withstand voltage test must be with iron wire with each current terminal ground connection again that is together in series for testing crew, nearly 10～20 current terminals in every switch cubicle, each minimum 5 switch cubicles of will connecting of high pressure withstand voltage test in the project in batch, so, all will spend the plenty of time before each withstand voltage test carries out this preparation.
Said method was both backward in technique, lost time again, and because the minority current terminal can be often missed in operating personnel's carelessness, increased unnecessary inspected number.
The utility model content
Problem to be solved in the utility model provides a kind of instrument of quick short circuit current terminal, its objective is the operating efficiency and the qualification rate that improve exfactory inspection.
To achieve these goals, the technical scheme taked of the utility model is:
The instrument of quick short circuit current terminal provided by the utility model, the instrument of described quick short circuit current terminal is provided with the current terminal brace, described current terminal brace is provided with a plurality of screws prong is installed, described screw installation prong is the slit opening on current terminal brace side, on each described screw installation prong, establish an attachment screw, and described attachment screw is fixed on the described current terminal brace with nut.
For making the utility model more perfect, more detailed and concrete technical scheme below also further having proposed, to obtain best practical function, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
The specification of described attachment screw is M4 * 10.
It is 10 that described screw is installed prong.
The utility model adopts technique scheme, at existing problem in the high pressure withstand voltage test, replaces iron wire with above-mentioned instrument, reduces the workload of testing crew greatly, improves the operating efficiency and the qualification rate of exfactory inspection; Draw materials conveniently, method is simple, and is convenient to check, current terminal is connected reliably, reduces misoperation.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is the structural representation of brace in the utility model;
Fig. 2 is an assembly structure schematic diagram of the present utility model.
Be labeled as among the figure:
1, current terminal brace, 2, attachment screw, 3, nut, 4, screw installs prong.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, Fig. 2 is a kind of instrument of quick short circuit current terminal.In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize improving the operating efficiency of exfactory inspection and the goal of the invention of qualification rate, the technical scheme that the utility model is taked is:
As depicted in figs. 1 and 2, the instrument of quick short circuit current terminal provided by the utility model is provided with current terminal brace 1, described current terminal brace 1 is provided with a plurality of screws prong 4 is installed, described screw installation prong 4 is the slit openings on current terminal brace 1 side, on each described screw installation prong 4, establish an attachment screw 2, and described attachment screw 2 is fixed on the described current terminal brace 1 with nut 3.
Current terminal brace 1 as shown in fig. 1 and several attachment screws 2, nut 3 structure as shown in Figure 4 that combines, this instrument is that the screw that each attachment screw 2 injects current terminal brace 1 is respectively installed prong 4, and is fixed from behind with nut 3 and just can.
The specification of attachment screw 2 described in the utility model is M4 * 10.
It is 10 that screw described in the utility model is installed prong 4.Because of general commonly used current terminal brace 1 all is whole 10 one group, so the instrument that each from now on every switch cubicle of high pressure withstand voltage test only need be used 1～2 so quick short circuit current terminal directly inserts current terminal and just can achieve the goal, and has improved operating efficiency.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection range of the present utility model.
