Abstract
The utility model relates to a portable test instrument is used to mutual -inductor, characterized in that: including the insulated handle, the wire couple, meet line block, outer binding post and plug terminal, the insulated handle is including portion of gripping and integrative supporting part one -tenth rather than the rigid coupling, the rigid coupling has the wire couple and meets line block on the supporting part of insulated handle, it is equipped with outer binding post and plug terminal on the line block to connect, outer binding post includes external connection left end and external connection right -hand member, the plug terminal includes plug left end and plug right -hand member, external connection right -hand member and plug right -hand member UNICOM in meeting line block, external connection left end and plug left end UNICOM in meeting line block. The advantage is: can reduce operation personnel's working strength and operational risk by a wide margin, improve experimental prescription, shorten the work flow time, solve traditional when experimental complex operation, the low scheduling problem of tentation data rate of accuracy, adopt this test instrument to guarantee the experimental security and the accuracy of tentation data.
Description
Technical field
The utility model belongs to mutual inductor detection technique field, particularly relates to the portable test instrument of a kind of mutual inductor.
Background technology
The secondary connection of the current transformer of powering for Self-power protective device divides four intervals, and mounting means is plug-in.When testing, due to the mode of connection special construction and lack special test instrument, the test of this special mutual inductor has been become to the new problem in experiment work.Traditional special mutual inductor secondary connection test method be plug interval in first insert copper cash, then with wiring card subcard live copper cash realization connect.There is following shortcoming in this test method: copper cash is fixed in plug interval very difficult by testing crew, and not only length consuming time but also contact insecure, owing to contacting instability, and then directly affects the accuracy of test figure.In order to avoid there is erroneous judgement, testing crew often needs repetition test, causes wasting time and energy, and once there is erroneous judgement, not only can cause the waste of material, even also can occasion a delay and make the consequence of duration.
Summary of the invention
The utility model provides a kind of and increases substantially test figure accuracy rate and efficiency and can reduce the portable test instrument of mutual inductor of testing crew working strength and operational risk for solving in known technology the technical matters that exists.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
The portable test instrument of mutual inductor, it is characterized in that: comprise insulated handle, wire hook, tagblock, external wiring terminal and pluggable terminals, described insulated handle comprises grip part and the all-in-one-piece support portion affixed with it, the support portion of described insulated handle is connected with wire hook and tagblock, described tagblock is provided with external wiring terminal and pluggable terminals, described external wiring terminal comprises external connection left terminal and external connection right terminal, described pluggable terminals comprises plug left terminal and plug right terminal, described external connection right terminal and plug right terminal UNICOM in tagblock, described external connection left terminal and plug left terminal UNICOM in tagblock.
The utility model can also adopt following technical scheme:
Described wire hook is vertical with the support portion of insulated handle affixed.
The length of described external connection left terminal and external connection right terminal is equal with the wiring length of actual tests instrument.
Described plug left terminal is equal with length with the connection terminal diameter of mutual inductor with length with plug right terminal diameter.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, when carrying out mutual inductor secondary connection test, pluggable terminals by this test instrument inserts in the connection terminal of mutual inductor, significantly can reduce working strength and the operational risk of operating personnel like this, improve test timeliness, shorten job flow time, the problems such as complex operation when solving traditional experiment, test figure accuracy rate are low.This test instrument is adopted to ensure that the security of test and the accuracy of test figure.In addition, the utility model also has the advantages such as structure is simple, light and flexible, safety and stability, cost of manufacture are low and practical.
