Abstract

The utility model discloses a novel fixing device for a withstand voltage electrode of a capacitor core. A fulcrum bar I and a fulcrum bar II are opened with a groove I and a groove II in a horizontal direction respectively; the groove I and the groove II are clamped with a pulley I and a pulley II respectively; a linker is opened with a chute in a longitudinal direction; a front and rear ends of the chute are clamped with a fixed wheel I and a fixed wheel II respectively; an upper and lower ends of a spring I are fixed on the fixed wheel I and the pulley I respectively; and an upper and lower ends of a spring II are fixed on the fixed wheel II and the pulley II respectively. A test electrode is clamped on the chute, and when the spring I and the spring II are at the free state, the bottom level of the test electrode is lower than that of the fulcrum bar I and the fulcrum bar II. According to the novel fixing device, manpower is not involved in the whole boosting process, electric shock hazards are prevented, and the test safety coefficient is raised.

Description

The withstand voltage electrode fixing device of a kind of novel capacitor fuse

Technical field

The utility model relates to a kind of device that the withstand voltage electrode of capacitor body is fixed.

Background technology

At present, need two people to finish when capacitor body is withstand voltage, wherein a people arrests the testing position of test electrode contact fuse end by hand, and another person presses the operating switch of voltage resistant instrument and finishes test.Trial voltage is 2 kilovolts, for the operator by test electrode, has great Danger Electric shock risk, if operator's hand is loosening a little, the situation of loose contact will occur.If this situation occurs in the process of boosting, the phenomenon that can occur discharging, if occur in the step-down process, the fuse discharge will be not thorough, brings great danger for the operator of postorder.From another point of view, this with the full automatic power capacitor pilot system that adopts at present extensively in reduce gradually even to eliminate manually-operated trend inconsistent.

Summary of the invention

Bring the deficiency of Danger Electric shock risk in order to overcome present manual contact electrode, the utility model provides a kind of novel capacitor fuse withstand voltage electrode fixing device, its technical scheme of taking is: this device comprises pole I, pole II, spring I, spring II and trace, pole I and pole II horizontal parallel are laterally placed, trace is positioned at pole I and pole II top and level and vertically places, have horizontal groove I and groove II on pole I and the pole II, be connected with respectively pulley I and pulley II on groove I and the groove II, pulley I can horizontally slip along groove I, pulley II can horizontally slip along groove II, have longitudinally chute on the trace, the rear and front end of chute is connected with respectively fixed wheel I and fixed wheel II, the upper and lower side of spring I is separately fixed on fixed wheel I and the pulley I, the upper and lower side of spring II is separately fixed on fixed wheel II and the pulley II, experimental electrode is connected on the chute, and can before and after chute, slide, when spring I and spring II were in free state, the bottom water plane of test electrode was lower than pole I and pole II bottom water plane.

The utility model is by trace move left and right on pole I and pole II, experimental electrode front and back on trace are mobile simultaneously, the experiment position of capable of regulating experimental electrode, when pole I and pole II bottom water plane are on the experiment plane, spring I and spring II are stretched, the bottom of experimental electrode is closely withstood on the experiment plane, reach the fixedly purpose of experimental electrode, avoided the phenomenon of virtual connection.

The utility model is in whole pressure process, and artificial the participation do not avoided Danger Electric shock risk, has improved the safety coefficient of test.Only need people's operation can finish the withstand voltage whole process of the test of fuse, saved the labour.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

As shown in Figure 1, pole I1 and pole II2 horizontal parallel are laterally placed, trace 5 is positioned at pole I1 and pole II2 top and level and vertically places, have horizontal groove I6 and groove II7 on pole I1 and the pole II2, be connected with respectively pulley I8 and pulley II9 on groove I6 and the groove II7, have longitudinally chute 10 on the trace 5, the rear and front end of chute 10 is connected with respectively fixed wheel I11 and fixed wheel II12, the upper and lower side of spring I3 is separately fixed on fixed wheel I11 and the pulley I8, and the upper and lower side of spring II4 is separately fixed on fixed wheel II12 and the pulley II9.Experimental electrode 13 is connected on the chute 10, and the afterbody of experimental electrode 13 has circular hole, is used for the joint test wire.This device is except experimental electrode 13 and partially conductive that fuse contacts, and all the other are insulating material, have avoided operator's Danger Electric shock risk.

Test electrode 13 can move forward and backward in trace 5, and pulley I8 and pulley II9 can drive trace 5 move left and right in groove I6 and groove II7, so test electrode 13 can arrive any position between pole I1 and the pole II2.Under the normal condition, the bottom water plane of test electrode 13 is lower than pole I1 and pole II2 bottom water plane, upwards spur trace 5, make spring I3 and spring II4 be in extended state, adjust test electrode 13 to testing position this moment, unclamp trace 5, the base plane of test electrode 13 contacts with testing position, both be in the same level face with pole I1 and pole II2 bottom water plane, spring I3 and spring II4 still are in extended state, this pulling force makes the test plane close contact of test electrode 13 and fuse, has avoided the phenomenon of virtual connection.
