Abstract
Survey a dual-purpose probe for disc type suspension insulator null value and insulation resistance, it is simple that the purpose of this utility model is to provide a kind of structure, the easy to operate disc type surveyed suspension insulator null value and the dual-purpose probe of insulation resistance.The technical solution of the utility model is, a kind of dual-purpose probe surveying disc type suspension insulator null value and insulation resistance, it comprises insulcrete, insulcrete is 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 utility model 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.
Description
Technical field:
The utility model 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:
It is simple that the purpose of this utility model is to provide a kind of structure, the easy to operate disc type surveyed suspension insulator null value and the dual-purpose probe of insulation resistance.
The technical solution of the utility model 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 utility model 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 utility model.
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 the utility model by the electric pressure adjusting play electrode distance according to surveyed disc type suspension insulator: when disc type suspension insulator electric pressure is 110kV; 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 utility model 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 utility model 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.
