Abstract
Disclosed is a double-purpose probe capable of measuring a zero value and the insulation resistance of a disc type suspension insulator. The double-purpose probe capable of measuring the zero value and the insulation resistance of the disc type suspension insulator is simple in structure and convenient to operate. According to the technical scheme, the double-purpose probe capable of measuring the zero value and insulation resistance of the disc type suspension insulator comprises an insulation plate; probe pins are fixed to the insulation plate; two metal balls with thread holes are connected to the lower portion of the insulation plate; clearance electrodes are assembled in the holes of the metal balls; the central lines of the two clearance electrodes are arranged on the same straight line; pluggable type wires are arranged on the probe pins and the tail ends of the clearance electrodes; the metal balls can be assembled on and disassembled from the insulation plate. The double-purpose probe is convenient to operate, and in the adjusting process of discharge clearances, measuring tools like a caliper are not needed, and functions of electrified detection and power failure detection are integrated; the zero value test work of the disc type suspension insulator can be achieved under the electrified condition or the power failure condition.
Description
Technical field:
The present invention relates to the pick-up unit can surveying disc type suspension insulator, particularly a kind of dual-purpose probe surveying disc type suspension insulator null value and insulation resistance.
Background technology:
The disc type suspension insulator null detection of transformer station is the major way detecting insulator dielectric performance, is one of the test item that must do; The null detection of current disc type suspension insulator mainly contains two kinds of methods, and one utilizes spark-discharge gap to carry out live detection, the another kind of insulation resistance for testing insulator chain after power failure with megohmmeter.Two kinds of method of testings all need to use probe apparatus, but the probe of two kinds of feeler levers can not be used with.The probe of live testing has spark-discharge gap, and the gap length of existing spark-discharge gap needs to adjust according to electric pressure slide calliper rule, inconvenient operation; The probe tested that has a power failure then needs the joint facilitating connecting lead wire and then be connected with megohmmeter.
Summary of the invention:
The object of this invention is to provide a kind of structure simple, the easy to operate disc type surveyed suspension insulator null value and the dual-purpose probe of insulation resistance.
Technical scheme of the present invention is, a kind of dual-purpose probe surveying disc type suspension insulator null value and insulation resistance, it comprises insulcrete, it is characterized in that: on insulcrete, be fixed with probe, insulcrete bottom is connected with two Metal Ball with threaded hole, in the hole of Metal Ball, be equipped with clearance electrode, and the center line of two clearance electrodes point-blank, the end of probe and clearance electrode is provided with the wire of plug type, and Metal Ball is dismantled and assembled on insulcrete.
The present invention is easy to operate, and the adjustment carrying out discharging gap again with survey instruments such as slide calliper rule, and need not integrate live detection and power failure detection function, all can meet the null detection work of disc type suspension insulator under charged or power-off condition.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment:
Describe embodiment in detail by reference to the accompanying drawings, a kind of disc type suspension insulator null value, megger test probe instrument, it comprises insulcrete 1, insulcrete is connected with probe 2, insulcrete bottom is connected with two Metal Ball 5 with threaded hole, the hole of Metal Ball is connected with the clearance electrode 3 coordinated with it, the center line of two clearance electrodes point-blank, probe and the end of clearance electrode are be connected with the wire 4 of plug type, and Metal Ball can be pulled down from entirety insulcrete, itself and insulcrete can be spirally connected or grafting.
In use, during live detection, two clearance electrodes are all rotated to end can not rotate again to centre by the electric pressure adjusting play electrode distance according to surveyed disc type suspension insulator: when disc type suspension insulator electric pressure is 110kV in the present invention; When disc type suspension insulator electric pressure is 220kV, rotated to high order end can not rotate again by left side clearance electrode, right side clearance electrode rotates to centre can not rotate again; When disc type suspension insulator electric pressure is 500kV, left side clearance electrode is rotated to high order end can not rotate again, right side clearance electrode is rotated to low order end can not rotate again.Again by plug type wire linking probe and clearance electrode, finally the present invention is connected on insulating bar, operating personnel's hand-held bar is by probe slowly near insulator two ends metal cap, if produce or nothing sound of ripping, tittering, frying, burning, etc sound without electric arc near post gap electrode, then insulator is null value.
When power failure detects, clearance electrode and Metal Ball are taken off in the lump, again the wire of plug type is connected to megohmmeter (other end is connected with probe) by other wire, finally the present invention is connected on insulating bar, operating personnel's hand-held bar, by probes touch insulator two ends metal cap, then shakes megohmmeter and carries out megger test.
