Abstract
The utility model discloses a special joint for testing the resistance of an ABB switch circuit. The special joint for testing the resistance of an ABB switch circuit comprises a joint body, one end of the joint body is a semispherical insertion terminal, and the other end of the joint body is a rectangular test wire terminal. When the special joint for testing the resistance of an ABB switch circuit is in use, the semispherical insertion terminal is inserted into the contact of an ABB switch, a transition resistance can be minimized, a test wire is connected by the test wire terminal for a test, the problem that the resistance of the ABB switch cannot be tested by a prior normal tester is solved, not only is the work efficiency raised, but also the test precision of the resistance of the circuit is raised, the integral work time is shortened, and an economic benefit is raised.
Description
Technical field
The utility model relates to a kind of switch loop resistance testing tool, is specifically related to a kind of joint of the ABB of test switch loop resistance.
Background technology
Cause power outage in electric system for preventing faults such as equipment deficiency, need regularly do the equipment preventive trial, to guarantee that electric equipment operation is in optimum condition.One of them project of electrical test is exactly the loop resistance of measuring switch equipment.Homemade switch for common is clipped in test wire on the switch static contact and can tests.But this method is infeasible for ABB VD4 type switch, because ABB VD4 type switch is closed, has only movable contact exposed outside.So, do not reach the requirement of doing the loop resistance test, so do not reach good test effect with common test equipment because that contact is movable excessive resistance ratio is bigger.
The utility model content
The technical matters that the utility model will solve is the loop resistance that existing test wire clamp can't accurately be measured the ABB switch, and a kind of ABB switch loop resistance test special joint is provided, and can utilize existing test wire clamp to detect the loop resistance of ABB switch.
The technical scheme of the utility model realizes in the following manner: a kind of ABB switch loop resistance test special joint, comprise joint body, and joint body one end is the semisphere insertion end, the joint body other end is cuboid test wire terminals.
Said joint body is the body that copper constitutes, and joint body is covered with anti-oxidation tin layer outward.
When the utility model used, the semisphere insertion end was inserted the contact of ABB switch, can reduce transition resistance; Utilizing the test wire terminals to connect test wire afterwards can test; Remedied the problem that in the past can't test the ABB switch resistance, not only improved work efficiency, and improved the precision of test loop resistance with conventionally test equipment; Shorten the whole time of work, improved economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of ABB switch loop resistance test special joint comprises joint body 1, and joint body 1 one ends are semisphere insertion end 2, and joint body 1 other end is cuboid test wire terminals 3.
Said joint body 1 is the body that copper constitutes, and is covered with anti-oxidation tin layer outside the joint body 1.This kind can reduce the resistance of device, prevents the joint surface oxidation.
ABB VD4 type switch is hermetically sealed insulation system, and having only contact is the conductor structure that exposes, and excessively resistance is bigger, does not reach the requirement of doing the loop resistance test.Semisphere insertion end 2 can conveniently be inserted the contact of ABB VD4 type switch in the utility model, can reduce excessive resistance.During use, with the contact of semisphere insertion end 2 insertion ABB VD4 type switches, connecting test wire at the test wire terminals then can test, and has remedied the problem that in the past can't test with conventionally test equipment.
Claims (2)
1. an ABB switch loop resistance is tested special joint, and it is characterized in that: comprise joint body (1), joint body (1) one end is semisphere insertion end (2), and joint body (1) other end is cuboid test wire terminals (3).
2. ABB switch loop resistance test special joint according to claim 1, it is characterized in that: said joint body (1) is the body that copper constitutes, and is covered with anti-oxidation tin layer outside the joint body (1).
