Ground connection isolator interlock

The utility model relates to an earthing switch isolator interlock, including the slider fixed strip, combination formula slider, ground connection, keep apart the interlocking device crank, crank dish and rotation axis, wherein the connecting hole is established on the surface to slider fixed strip one side, the composite slider includes connecting rod and connector, connector and ground connection, isolator interlocking device crank one end is articulated, the crank dish is installed at the rotation axis both ends, fan -shaped constant head tank is established in addition to its side surface of connecting axle, driving -disc center department establishes shaft hole and circular arc spread groove, the driving -disc passes through the shaft hole and is connected with the rotation axis, the spread groove is through connecting pin and ground connection, keep apart interlocking device crank connection. This novel can be by providing reliable chain control between the ground connection of uses in the solid insulation looped netowrk cabinet, isolator's branch, combined floodgate running state, overcome that traditional dependence spring structure involves that interactive mechanism is short of power with driving of emergence and drawback such as spring jamming, ground connection, isolator operating stability and security has improved.
