High -Voltage Isolating Switch
Product overview
Neutral isolating switch, is for frequency 50 Hz ac frequencies of high voltage outdoor electrical equipment, have 40.5 kV, 72.5 kV and 126 kV voltage grade three, for no load in the case, points, and the use of on-line transformer neutral point.
structure
Isolating switch by base, post insulator, conductive circuits, wiring board components. In an increase in housing with external note nozzle connected cast iron oil way, can not achieve decomposition products and directly in the external note oil, greatly reducing the workload; Improve the insulated cover up and down into the oil can avoid airing, housing and support increased in the gasket, effective to prevent the loss of oil; Porcelain column, under cement in plastic loaded with waterproof fast solid glue, can prevent the crack due to water ice and unrelenting frosty; Diversion system to increase in touch at the end of the conductive piece, realize the conductive transition, making contact resistance is greatly reduced, conductive reliability obviously improved.
Above can reduce the maintenance of improvement work, improve product performance, prolong service life.
