Description
Technical field
The utility model relates to the little arc test device of a kind of disc insulator, belongs to Insulators Used detection experiment device.
Background technology
Dish type toughened glass insulator is one of widely used three major types insulator of overhead transmission line, has superpower resistance to environmental aging, " need not survey zero ", without technical advantages such as the anxieties of disconnected string after self-destruction.Self-destruction rate is the important parameter characterizing glass insulator product quality and running quality, requires that year self-destruction rate is no more than 0.2 ‰.It is generally acknowledged that the self-destruction rate of emerged in operation exceeds standard and belong to product quality problem, comprise in glass workpiece the impurity that there is certain particle diameter and glass workpiece tempering bad etc., such self-destruction insulator spatially distributes and relatively to disperse, evenly, run first 2 ~ 3 years self-destruction rates in time relatively high, the later stage tends to be steady.
Except the self-destruction of the said goods deficiency or claim the self-destruction of internal cause type, also there are following 3 kinds of known external cause type self-destructions in glass insulator: the large electric arc type self-destruction of the external force striking type self-destructions such as cut into a mountain fried stone, gunslinging, the self-destruction of big current thunderbolt type and power frequency short circuit.This 3 class external cause type self-destruction limited amount, less on the impact of operation of power networks generally, but glass insulator frequent generation the under heavy rain Rainfall Condition running on heavily contaminated region in recent years concentrates self-destruction, as: certain the 220kV circuit strain insulator-string 18 sheet glass insulator running 7 years for 2014 reveals 15, certain the 500kV circuit linear string 28 sheet glass insulator running 12 years for 2013 reveals 13, relate to Liaoning, Hebei, Ji Bei, Zhejiang, Jiangsu, the electrical networks such as Anhui, this self-destruction be embodied in the time concentrate and spatial concentration two aspects, and the probability of occurrence of heavily contaminated and heavy rain Rainfall Condition is relatively large, therefore the concentrated self-destruction that this extreme climate environment causes has formed the serious threat of electric power netting safe running, incomplete statistics shows: this glass insulator running on seriously polluted area is at heavy rain, after concentrated self-destruction in heavy rain is quantitatively only positioned at " self-destruction of product defects type ", and be far longer than on other various external cause type self-destruction.
The concentrated self-destruction that above-mentioned extreme climate environment causes has following characteristics: (1) self-destruction glass insulator all runs on heavily contaminated environment, comprises heavy dust pollution district.(2) under self-destruction mainly occurs in heavy rain, Rainfall Condition.(3) larger proportion self-destruction insulator batch runs more than 2 years, the longest 13 years, exceedes the self-destruction high-incidence season even substantially exceeding glass insulator, enters the steady operation period on ordinary meaning.(4) reveal when and where to concentrate, this and product defects type are revealed rule and are not inconsistent.(5) reveal insulator both with or without antifouling flash coating layer batch, also have band coating batch, but band coating batch is field-applied, and the general coating quality of insulator lower surface is poor, comprises that holiday, coating are partially thin, poor adhesive force.(6) inside the same batch of insulator glass part lower surface partly do not revealed there is local damage in boss, namely concentrates self-destruction starting point on this boss.(7) part band coating insulator lower surface coating has arc erosion vestige, although namely there is not overall short circuit tripping operation, not forming the large electric arc of short circuit, there is little electric arc and the coating of ablation insulator lower surface and glass workpiece in insulator lower surface.(8) conventional sense of self-destruction insulator be can not determine to there is product defects.Think: this little electric arc of intermittence concentrating self-destruction and heavily contaminated environment and heavy rain Rainfall Condition to produce on glass insulator has direct relation, and the little electric arc of intermittence particularly produced at glass insulator lower surface has direct relation.
Comparatively speaking, the self-destruction process duration of the self-destruction of power frequency short circuit large electric arc type and the self-destruction of big current thunderbolt type is very short, is respectively uS and mS level, the little electric arc self-destruction process then duration much longer (min level is h level even) under heavy rain/Rainfall Condition.Impulse breakdown test (DL/T557-2005, GB/T20642-2006) in Voltage for Insulators on HV Lines air can be adopted to carry out modeling effort for the self-destruction of big current thunderbolt type, the large arc test of power frequency (DL/T812-2002) can be adopted to carry out modeling effort for the self-destruction of power frequency short circuit large electric arc type; But suitable test method be there is no for the little electric arc self-destruction under heavily contaminated and heavy rain Rainfall Condition and test unit can be used.The little electric arc experimental provision of disc insulator proposed by the invention can be used for the little electric arc self-destruction mechanism studying and verify disk-like glass insulator, for studying and verify the prophylactico-therapeutic measures of the little electric arc self-destruction of disk-like glass insulator, for studying the operation characteristic of dish type porcelain insulator under little arcing.
