Kev Paub Txog Composite Insulators

Insulator Technical Parameters:

1. Ntsuas qhov hluav taws xob: DC kwv yees li . 5000V

2. Kev ntsuas qhov ntsuas: 0-1999 MΩ

3. Kev daws teeb meem: 1MΩ

4. Qhov tseeb: ± 5%

5. Tsim nyog ntev insulating kev khiav hauj lwm pas nrig (tube) muaj raws li tus neeg siv thov.

Nyob rau hauv tib lub ntsev ceev, lub flashover voltage ntawm lub insulator nce nrog txo cov tshauv ntom.

When the dust density on the insulator surface is too low, the water absorption and retention of the contaminants are small. Sab saum toj, uas yog yooj yim cuam tshuam los ntawm noo noo, sai sai yuav saturated nrog noo noo thiab pib ntsws nrog dej, thaum cov kab mob nyob rau hauv lub qis nto tseem tsis tau tag nrho moistened. Yog li ntawd, qhov nto conductivity ntawm lub insulator yog tsis siab, thiab lub flashover voltage yog tsawg. Within the dust density range, the water absorption and retention of the contaminants are both good. Sab saum toj yog moistened tag nrho thiab cov dej noo tseem tsis tau shrunk, thaum lub hauv qab nto kuj yuav luag saturated nrog noo noo. Thaum lub sij hawm no, qhov nto conductivity ntawm lub insulator yog siab. When the dust density is too high, the contaminant layer becomes thinner, and it often happens that the bottom of the contaminant layer on the lower surface has not yet become moistened, while the contaminant layer on the upper surface has softened too much and begun to shrink, causing the contaminant withstand voltage curve to show a downward trend.
