Description
Technical field
The invention mainly relates to technical field of power systems, refer in particular to a kind of insulator creep age distance survey tool.
Background technology
Power transmission and transforming equipment pollution flashover accident seriously threatens safe operation of electric network, be power system guard key major accident it
One.Increase with environmental pollution, the antifouling grade of converting equipment can not meet the antifouling needs in scene.According to " national grid
O＆M maintenance portion of company with regard to carry out power transmission and transformation equipment outer insulation configuration check work notice " requirement, need to accurately measure and
Grasp field apparatus external insulation creep age distance, in order to carry out the antifouling control of field apparatus.
The method of measurement insulator creep age distance is more extensive, mainly by using different measuring material manual measurement at present
And calculating result, measurement efficiency and accuracy are all fairly limited.
The method of the creep age distance of measurement insulator mainly has three kinds at present, and respectively leather measuring tape measurement method, adhesive tape class are surveyed
Mensuration and fine cordage class measurement method, below various measuring methods are briefly introduced:
(1) leather measuring tape measurement method: directly measured along insulator bending surface with leather measuring tape, its shortcoming is that leather measuring tape is easily sliding
Move it is impossible to insulator surface of tightly fitting, need to repeatedly adjust the time loss causing to measure, produce larger measurement by mistake simultaneously
Difference；
(2) adhesive tape class measurement method: bend surface mount using black tape (or other adhesive adhesive tape etc.) along insulator, then
Shut down and after stretching, use tape measure length.Adhesive tape has certain ductility, pasting, tears and takes process to cause certain measurement by mistake
Difference, and the method is indirect method, relatively straight connection can consume the regular hour more, and adhesive tape can not be reused；
(3) fine cordage class measurement method: bend table along insulator using fine cordage (or other soft objects not having stickup property) again
Face laminating compares, and then takes off and uses tape measure length after stretching.Fine cordage class material diameter is larger or material is harder it is impossible to tight
Close be pasted onto porcelain vase surface it is impossible to linearly measure completely, time-consuming again has larger error.
Analyze by inquiry, it can be found that current traditional measurement method troublesome poeration, efficiency is low, and (used time exists time length
5min to 30+min, comprehensive average 19 minutes used times), accuracy low (measurement data deviation has dozens or even hundreds of millimeter,
Comprehensive averagely every thousand millimeters errors 38mm).
