Counterbore is connected, is connect by spring touch finger with switch copper guiding element.Casing electrified sensor is located at conductive copper piece and cable end flanges
Between insulating layer in, covering cable sealing cone and cable end flanges interface, uniform cable and cable end flanges transition face
Between electric field.There are 2 symmetrical casing sensor connectors in the middle part of cable end flanges.Switch connecting pin outer cone flange with
There is outer cone electrified sensor in insulating layer between conductive copper piece, there are 2 symmetrical outer cone sensings in the middle part of outer cone flange
Device connector.There is semi-conductive buffer layer in conductive copper piece outer surface between casing electrified sensor and outer cone electrified sensor.Gu
The disconnected position in body insulating materials surface, solidification have semiconductive shielding layer.Electrified sensor also acts the effect of uniform electric field.
Semi-conductive buffer layer main function be eliminate tip, burr etc. existing for electric conductor surface influence shelf depreciation because
Element；Simultaneously in electric conductor adstante febre, the stress because expanding with heat and contract with cold between bring solid insulating material and electric conductor is buffered, is avoided
Generate gap and solid insulating material cracking.The resistance value of semi-conductive buffer layer is between 3000 ohm to 6000 ohm.Partly lead
Electric buffer layer thickness is between 0.5-2 millimeters.The main component of semi-conductive buffer layer is carbon dust and silicon rubber.Semi-conductive buffer layer
Carbon dust is added after mixing using silicon rubber liquid, electric conductor sealing position is sprayed on, then solidifies, then to the buffering after solidification
Layer outer surface sandblasting polishing, cleaning carry out sealing finally by compression moulding die is packed into.
The beneficial effects of the utility model are: 1, using solid insulating material, reduce the volume of casing；2, it uses equal
Casting die and semi-conductive screen ground plane, reduce the partial discharge quantity of product；3, half is used between electric conductor and fixed sealing material
Conductive buffer layer improves the insulation life of product and the safety in operation of product.
