Line, the upper end of binding post is provided with screwed hole, and this screwed hole is positioned at transverse passageway and vertical cavity intersection, binding post
Threaded at screwed hole have conducting rod.The other end of conducting rod is connected with the binding post on chopper, the outside of conducting rod
Being provided with insulating joint, the right part of insulating joint is placed in transverse passageway.
Earth connection point and electrical verification contact it is provided with at the vertical part of described insulation elbow plug.
The right part of described insulating joint is conically shaped or column type, the transverse passageway on described insulation elbow plug
Shape is closed with insulating joint matching form.
The transverse part right part of described insulation elbow plug is blind end, the vertical sky in the vertical part of described insulation elbow plug
Lower end, chamber communicates with the external world, and the insulated conductor other end in described vertical cavity is placed in the outside of vertical part.
The invention have the advantage that
1. the plug-in lead riser of chopper be all insulation, totally-enclosed can the plug-in termination head of charged touch, seal is good
Good, stable chemical nature.Can be effective against the corrosion of chemical gases and acid rain, wire clamp corrosion ratio is low.Whole body insulation raising makes
With the life-span, it is difficult to that unit trip fault and phase fault occur, is particularly well-suited to building ring such as high filthy district and Craft in Chemical Industrial Area etc.
Border.
2. plug-in lead riser can make the area of conductor contact surface increase twice, it is ensured that is completely embedded, efficiently solves
The fever phenomenon that contact the most closely causes.Mount and dismount convenient and swift, substantially reduce lead-in wire installation and removal time, joint
Human-saving material resources.
3. test point can install electrification display, in order to query facility electriferous state, also can meet circuit nuclear phase requirement.
4. conducting rod union joint has arc quenching material, therefore can operate in the energized state, beneficially line live-line work
Maintenance.
