Description
Technical field
The invention belongs to electric power project engineering field, particularly relate to a kind of portable suspended porcelain insulator null value and low value testing tool.
Background technology
If null value, low value situation appear in overhead transmission line top suspension porcelain insulator, the dielectric strength of bunch of insulator can be had influence on, line tripping may be caused and then cause power outage.According to overhead transmission line suspended porcelain insulator service requirement, all need every year to carry out zero value detection to it, so that Timeliness coverage null value, low value disordered insulator.In transmission line of electricity runs, suspended porcelain insulator zero value detection method conventional at present has two kinds, one is that insulation resistance meter is placed on shaft tower basal plane, a staff will test tape upper boom tower and wiring, another staff is also responsible for operating instrument in ground wiring, after testing a slice insulator, operating personnel's rewiring on tower also carries out the test of next sheet, but, overhead power transmission line pole tower is general all higher than tens meters, and raise with electric pressure, highly may reach rice up to a hundred, adopt traditional test methods work difficulty larger; The second adopts mancarried device directly to measure on tower, and a probe points is at ball-and-socket, and another point is at bulb, this mode is comparatively convenient, but owing to visiting the impact by pin loose contact and insulator surface leakage current, only can measure zero resistance insulator, effectively can not measure low resistance insulator.
Summary of the invention
The present invention is directed to the defect that known technology exists, provide a kind of portable suspended porcelain insulator null value and low value testing tool, use this instrument, not only can reduce the workload of overhead transmission line operations staff, suspended porcelain insulator null value, low value Detection job and speed can also be improved.
A kind of portable suspended porcelain insulator null value and low value testing tool, comprise metal electrode module and insulation resistance meter module;
Wherein, described metal electrode module comprises ball-and-socket electrode 11, guarded electrode 12 and ball electrode 13;
Described insulation resistance meter module 2 is by insulation resistance meter 21 and switch 22;
Described ball-and-socket electrode 11 and ball electrode 13 are connected with two input ports of insulation resistance meter 21 respectively, and described guarded electrode 12 is connected with the shielding port of insulation resistance meter 21;
