Description

High pressure vacuum insulated circuit breakers plug-in pigtail splice
Technical field
The invention belongs to power equipment, particularly relate to a kind of high pressure vacuum insulated circuit breakers plug-in pigtail splice.
Background technology
10 kilovolts of choppers: being that one is switched off and on load circuit, and disengagement failure circuit, Accident prevention expands, Ensure the electrical equipment that line security runs.Because it has, volume is little, lightweight, non-maintaining, high reliability, by extensively In the distribution lines such as market, apartment, square, residential quarters.Current this on-pole switch is installed and removes cumbersome, Get the raw materials ready all shift to an earlier date ready in the case of need to spend 2 to 3 hours and just can complete more to renew switch.The turnover lead-in wire of switch is total Totally 6, each inlet wire needs 8 bolts, gets rusty easily and cause ageing equipment speed under the elbow-type joint protective that do not insulate Accelerate, multiple malfunctions.And owing to junction is on-insulated, when being easy to send out after the upper branch that falls, birds or other easy conductive material Raw phase fault is accidents caused, is particularly susceptible to short circuit accident in high filthy district and Craft in Chemical Industrial Area.
Summary of the invention
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of novel insulated type chopper plug Formula pigtail splice.This insulated type breaker structure is simple, it is simple to install operation, shortens the activity duration.It is prevented from wire clamp rust Erosion, is difficult to unit trip fault occur, breaks down and can conveniently isolate.
The present invention is achieved by the following technical solutions:
A kind of high pressure vacuum insulated circuit breakers plug-in pigtail splice, including chopper, described chopper is provided with six wiring Terminal, each binding post is provided with plug-in lead riser, and described plug-in lead riser includes that insulating joint and insulation elbow are inserted Head;Insulation elbow plug is made up of transverse part and vertical part, is provided with transverse passageway, is provided with vertical sky in described vertical part in described transverse part Chamber, transverse passageway is connected with vertical cavity, is provided with binding post in vertical cavity;The lower end crimping insulation of binding post is led 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
