Abstract
A kind of ground insulation for high pressure gas insulated switching installation, ground insulation in the prior art is overcome to be directly grounded by shell, the problem of influencing the accuracy of test gas-insulated switchgear performance, it is characterized in that the sub- middle conductor of ground insulation is installed in ground insulation subshell flange, epoxy casting layer is cast between the sub- middle conductor of ground insulation and ground insulation subshell flange, 2 grooves for preventing epoxy casting layer to be detached from are equipped between epoxy casting layer in the sub- middle conductor of ground insulation, it is equipped with to cooperate with the groove on epoxy casting layer on ground insulation subshell flange and can prevent the boss of ground insulation subshell flange disengaging, beneficial effect is that structure is simple, reduce the difficulty of processing of part, conducive to installation, maintenance and replacement components, improve product qualification rate, in test gas-insulated The accuracy for guaranteeing test gas-insulated switchgear performance when switchgear performance, facilitates the performance detection of gas-insulated switchgear.
Description
Technical field
The utility model belongs to high voltage electrical apparatus technical field, in particular to a kind of for high pressure gas insulated switching installation
Ground insulation.
Background technique
Ground insulation is the important electric connecting element in gas-insulated switchgear, is risen to gas-insulated switchgear
Very important effect, ground insulation is directly grounded by shell in the prior art, influence test gas-insulated switch set
The accuracy of standby performance.
Utility model content
Problem to be solved in the utility model is that in place of overcome the deficiencies in the prior art, providing one kind can tested
Guarantee that one kind of test gas-insulated switchgear performance accuracy is exhausted for high pressure gas when gas-insulated switchgear performance
Ground insulation of edge switchgear.
The technical solution adopted in the utility model includes ground insulation subshell flange, the ground insulation subshell flange
On be machined with multiple connecting holes, the sub- middle conductor of ground insulation is installed in the ground insulation subshell flange, is being grounded
Be machined in insulator middle conductor for the first threaded connection hole for connecting inside gas-insulated switch and be used for and gas
Second threaded connection hole of insulated switch external connection, between the sub- middle conductor of ground insulation and ground insulation subshell flange
It is cast with epoxy casting layer, the upper end of epoxy casting layer is equipped with the seal groove for placing sealing ring.
Epoxy casting layer is prevented to be detached from equipped with 2 between epoxy casting layer in the sub- middle conductor of the ground insulation
Groove, being equipped on ground insulation subshell flange can prevent ground insulation with the groove mutual cooperation on epoxy casting layer
The boss that housing flange is detached from.
Compared with prior art, the utility model structure beneficial effect is that structure is simple, reduces the difficulty of processing of part,
Conducive to installation, maintenance and replacement components, product qualification rate is improved；Meanwhile using the ground insulation energy of the utility model
The insulation being grounded between housing flange guarantees test gas-insulated switch when testing gas-insulated switchgear performance
The accuracy of equipment performance facilitates the performance detection of gas-insulated switchgear.
