Abstract

The utility model relates to the technique field of characteristic testing and maintaining devices in electric power industry and specifically relates to a multi-purpose joint used for measuring mechanical characteristics of a circuit breaker. In a C-class maintenance process of the handcart-type circuit breaker, quantity of maintenance projects is large, testing time is long, switch vibration is comparatively severe and the maintenance needs to be finished by a plurality of workers through cooperation. And potential safety hazards exist. The technical scheme of the utility model is that a joint body is outside wrapped with an insulation surface layer; and one end of the joint body is provided with a jack A connected with an insert pin while the other end of the joint body is provided with a jack B connected with a characteristic tester joint. The multi-purpose joint used for measuring the mechanical characteristics of the circuit breaker provided by the utility model has advantages that the multi-purpose joint used for measuring the mechanical characteristics of the circuit breaker is simple and reasonable in structure, convenient to carry and simple and convenient to operate; time cost for connecting a characteristic tester and a small-cart switch of the handcart-type circuit breaker is shortened; the maintenance working efficiency is improved; only one worker is needed for operation in a testing process, so that labor cost is reduced; and potential safety hazards in a testing process are eliminated.

Description

Breaker mechanic property is measured multipurpose joint
Technical field
The utility model relates to power industry characteristic test repair apparatus technical field, and specifically a kind of breaker mechanic property is measured multipurpose joint.
Background technology
In handcart type breaker C class maintenance process, the connectivity problem between characteristic tester and aviation plug-in unit is particularly outstanding.The project that the maintenance of C class comprises is more, it is longer that it finishes required time, the breaker mechanic property low-voltage starts and returns not only grow (about 30~40 minutes) consuming time of test, and need 3~4 staff to cooperate usually to finish, respectively by the special messenger be responsible for the hand held switch characteristic tester joint, handcart type breaker car switch aviation card cage, carry out test operation etc.Because the switch vibrations are very big, wiring has loosening slightly, will cause test failure in the process of the test; Especially the plug-in unit wiring stitch spacing in the card cage is nearer, two lines very easily occur and collides, and causes device damage, even the accident that causes the person to get an electric shock, and not only have potential safety hazard, and work efficiency is lower.
Summary of the invention
The purpose of this utility model provides a kind of breaker mechanic property and measures multipurpose joint, to overcome deficiency of the prior art, guarantees carrying out smoothly of experiment, eliminates the potential safety hazard in the test process, has improved work efficiency.
The technical solution of the utility model is: the outer wrap of adapter body has the insulation top layer; Adapter body one end has the jack A that connects the plug-in unit stitch, and the other end has the jack B of connection performance tester joint.
Further, the jack A inwall of described adapter body is the two ends diameter is equipped with the band groove greater than the curved surface of mid diameter or jack A inwall shell fragment.
The utility model has the advantages that: simple and reasonable, easy to carry, easy and simple to handle, significantly shortened the tie-time of characteristic tester and handcart type breaker car switch, improved service work efficient, and test process only needs staff's operation to get final product, saved cost of labor.
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is elaborated.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
Among the figure: 1, adapter body, 2, jack A, 3, jack B.
Embodiment 1
As can be seen from Figure 1, the technical solution of the utility model is: adapter body 1 adopts copper material, and the outside surface of adapter body 1 is enclosed with the insulation resin top layer, has light, tough and tensile firm, the good advantage of insulating property of quality; Adapter body 1 one ends have for the jack A 2 that connects handcart type breaker car switch plug-in unit stitch, and the other end has the jack B 3 of connection performance tester joint.Jack A inwall is equipped with the shell fragment of band groove, to increase the contact area of jack A and isolating switch car switch plug-in unit stitch, guarantees the accuracy of experimental result.
Embodiment 2
As can be seen from Figure 2, present embodiment as different from Example 1, described adapter body 1 end is used for connecting the jack A inwall curved surface two ends diameter of handcart type breaker car switch plug-in unit stitch greater than the middle part diameter, being jack A is the pillow type along the longitudinal cross-section of its axis, and the plug-in unit thinner with fit pin uses.
The utility model is simple in structure, easy to carry, rationally utilize the existing joint of switching characteristic tester, the tester joint is inserted in the jack B of the utility model adapter body, make adapter body connect handcart type breaker car switch plug-in unit again, need not the special messenger holds, avoid staff's unprotect test operation in the work, eliminated potential safety hazard; 3~4 required operating personnel of switching characteristic test in the former performulation are reduced to a people, have saved manually, reduced labour intensity, shortened the service work time, significantly improved work on the spot efficient.
Should be noted that at last: above embodiment is used for the explanation the technical solution of the utility model and is not intended to limit; the those skilled in the art makes amendment to embodiment or the part technical characterictic is equal to replacement; and do not break away from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
