Abstract
The utility model discloses a non-ascending contact resistance testing tool of a breaker, comprising a contact resistance tester and an upper-level jointing clamp, wherein the upper-level jointing clamp comprises an operating lever, a guide rod, an upper jaw and a lower jaw, and the contact resistance tester is connected with the upper-level jointing clamp in a jack connection mode. The upper jawand the lower jaw are respectively provided with jack connection posts for connecting wires to connect the contact resistance tester. The non-ascending contact resistance testing tool of the breaker has no bare conducting parts, prevents test controllers from getting an electric shock when contacting conductors, and eliminates screwdrivers or wrenches and the like. The non-ascending contact resistance testing tool of the breaker can be drawn out and plugged simply in hands to implement test, and is characterized by time-saving and labor-saving properties, convenient and practical performance,and safety and reliable operation, thereby greatly increasing working efficiency, and shortening power-off time. The non-ascending contact resistance testing tool of the breaker can be used for testing the contact resistance of the breakers of 35kV to 220kV, can implement test at the places where field high altitude lift trunks can not reach, and is applied to test the contact resistance of various short circuiting devices at any places.
Description
Technical field
The utility model relates to a kind of contact resistance testing tool, relates in particular to a kind of circuit breaker contact persistence testing tool of exempting to ascend a height.
Background technology
Traditional circuit breaker contact persistence testing tool generally includes contact resistance tester and high-altitude wiring pincers two parts, and wherein the contact resistance tester is an instrument of measuring various switchgear loop resistances.General 60～the 200A of employing constant current is exported, and maximum output voltage is 20V, and test specification reaches 100m Ω.The high-altitude wiring pincers are the instruments that cooperate the contact resistance tester to use, can't arrive local of staff or need climb up the higher switch of porcelain vase it is more convenient, alleviated user of service's labour intensity, but the high-altitude wiring of tester pincers link to each other by lead with the contact resistance tester, the junction is that traditional bare wire that passes through links to each other with the screw winding method, tester's mistake is bumped conductor and is caused the person to get an electric shock, and needs instruments such as outfit screwdriver or spanner to operate.
Summary of the invention
The purpose of this utility model is: overcome traditional above-mentioned defective of circuit breaker contact persistence testing tool, a kind of easy-to-connect be provided, do not have exposed conductor part, safe and reliable, efficiency is high exempts from the circuit breaker contact persistence testing tool of ascending a height.
The purpose of this utility model realizes by following scheme: be made up of contact resistance tester and high-altitude wiring pincers.The high-altitude wiring pincers are made of control lever, guide pole, bit, adopt the jack type mode of connection to connect between contact resistance tester and the high-altitude wiring pincers.
The utility model is provided for lead respectively and connects so that connect the jack type binding post of contact resistance tester on upper and lower jaw.
Jack type binding post inner conductive body described in the utility model and upper and lower jaw conductive part in succession, the outside is an insulator.
The utility model does not have exposed conductor part, having avoided tester's mistake to bump conductor causes the person to get an electric shock, instruments such as use screwdriver or spanner have been exempted, only needing simple manual plug is that two instruments capable of being combined are tested, time saving and energy saving, and it is simple in structure, convenient and practical, safe and reliable, improved work efficiency greatly, shortened power off time, can be used for measuring the contact resistance of 35kV-220kV isolating switch, for the place that open-air high-altitude lift truck can not arrive, also can be competent at, be applicable to any type of short-circuiting device contact resistance test in any place.
Description of drawings
Fig. 1 the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is made up of contact resistance tester 1 and high-altitude wiring pincers 2, high-altitude wiring pincers 2 are made of control lever 3, guide pole 4, bit 5,6, are respectively arranged with to be used for lead and to connect so that connect the jack type binding post 7,8 of contact resistance tester 1 on upper and lower jaw 5,6.Jack type binding post 7,8 inner conductive bodies and upper and lower jaw 5,6 conductive parts in succession, the outside is an insulator, the connector lug and the jack that connect lead closely cooperate.
During use, the field personnel only need couple together several sections insulating bars, and jaw tip is linked to each other with equipment, and vertical then rise is clipped in the both sides of switch respectively, only needs 2 people just can operate a measurement, a wiring.
