Two, sensor probe is cast in the epoxy resin of disc insulator inside.As shown in Figure 2, sensor 201 is arranged on disc insulator metal flange 202, described disc insulator metal flange 202 is arranged on disc insulator epoxy resin 203, in disc insulator epoxy resin 203, embed the internally charged body 204 of disc insulator, the probe 205 of described sensor 201 is cast in disc insulator epoxy resin 203.Its defect is: when described electrification in high voltage pick-up unit sensor damages, must change whole disc insulator, its maintenance workload is large, and risk is larger, affects the performance of high-tension apparatus, and improves die sinking production cost.
Summary of the invention
The object of the present invention is to provide a kind of electrification in high voltage pick-up unit, it installs simple, and sensor can local replacing and cost-saving, and can not cause sensor gas leakage.
For reaching above-mentioned purpose, solution of the present invention is:
A kind of electrification in high voltage pick-up unit, comprises disc insulator and sensor, and described disc insulator comprises support portion, insulation division and internally charged body, and support portion is arranged on insulation division, embeds internally charged body in insulation division; Installation of sensors is on disc insulator support portion, and the probe of sensor inserts in disc insulator insulation division.
Further, form perforation, and on insulation division, form jack on disc insulator support portion, probe, through support portion perforation, inserts in insulation division jack.
Further, described disc insulator support portion is metal flange, and disc insulator insulation division is epoxy resin, and metal flange is arranged on epoxy resin, embeds internally charged body in epoxy resin.
Further, described sensor comprises terminal box and probe; Terminal box is arranged on metal flange, is contained in terminal box, and inserts in epoxy resin and pop one's head in to water.
Further, also comprise display, described display is connected with sensor is electric.
Further, between metal flange and sensor, waterproof washer is set.
Adopt after such scheme, installation of sensors of the present invention is on disc insulator support portion, and the probe of sensor inserts in disc insulator insulation division, when the internally charged body of disc insulator is charged, the probe of sensor induces voltage signal, and voltage signal is transferred to display device.The present invention installs simply, and sensor can local replacing and cost-saving, and can not cause sensor gas leakage.
