Abstract
The present invention relates to a cable grounding tool of a cable branch box for completing the grounding working within a safe active range under the condition of no direct contact with the cable branch box, which belongs to the technical field of safety protection. The present invention is mainly composed of a grounding device and an insulating operation rod, wherein the grounding device is fixedly connected with the insulating operation rod. The present invention has the advantage of simple, compact and reasonable structure. In the process of grounding, operators do not need to contact cable parts, and the personal safety of the operators is ensured.
Description
Technical field
The present invention relates to a kind of earthing tool of cable of cable branch box, be used in the scope of activities of safety, directly not contacting under the situation of cable branch box cable, finish ground connection work, belong to the safety protection technique field.
Background technology
At present, domestic a plurality of producers have made elbow type earth cable joint at the single, double logical casing joint constitution equipment of box change and loop-network switch cabinet, can finish last ground connection work by this cable joint.But regrettably, have not yet to see special-purpose earthing tool,, exist great potential safety hazard so bring difficulty to the cable grounding operation of cable branch box power failure work.
Technology contents
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of simple, compact and reasonable for structure; In the ground connection process, operating personnel do not need directly to contact cable assembly, just can realize the instrument to 10KV cable branch box cable grounding.
Main solution of the present invention is achieved in that
The present invention mainly is made up of earthing device and insulating bar two parts, and earthing device and insulating bar are fastenedly connected.
Earthing device mainly is made up of the body 7 that is threaded, base 10, spring 8, spiral shell spare 13, intermediate plate 14 and pad 15, be threaded body 7 of employing is fastening with base 10, spring 8 is installed in and is threaded between body 7 and the base 10, spiral shell spare 13 fuses with base 10, and intermediate plate 14, pad 15 are placed on 13 of base 10 and spiral shell spares.
Insulating bar mainly is made up of special-shaped sleeve 1, insulating epoxy pipe 5, magnet steel 3, magnet steel seat 2 and lever 6, special-shaped sleeve 1 is connected with insulating epoxy pipe 5, magnet steel 3 is installed in special-shaped sleeve 1, and magnet steel 3 is placed on the magnet steel seat 2, and lever 6 is installed in insulating epoxy pipe 5 bottoms.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; In the ground connection process, operating personnel do not need to contact cable assembly, have guaranteed operating personnel's personal safety.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly is made up of special-shaped sleeve 1, magnet steel seat 2, magnet steel 3, fixed screw 4,9, insulating epoxy pipe 5, lever 6, the body 7 that is threaded, spring 8, base 10, bearing pin 11, lateral pin 12, spiral shell spare 13, intermediate plate 14, pad 15 etc.
The present invention mainly is made up of earthing device and insulating bar two parts, and earthing device and insulating bar are fastenedly connected.
Earthing device of the present invention mainly is made up of the body 7 that is threaded, base 10, spring 8, spiral shell spare 13, intermediate plate 14 and pad 15.Employing is threaded, and body 7 passes through screw 9 and base 10 is fastening, spring 8 is installed in and is threaded between body 7 and the base 10, and spiral shell spare 13 fuses by bearing pin 11 and base 10, and lateral pin 12 is contained on the spiral shell spare 13, intermediate plate 14, pad 15 are placed on 13 of base 10 and spiral shell spares, are convenient to the dead earth line and use.
Insulating bar of the present invention mainly is made up of special-shaped sleeve 1, insulating epoxy pipe 5, magnet steel 3, magnet steel seat 2 and lever 6.Special-shaped sleeve 1 is connected with insulating epoxy pipe 5 by fixed screw 4, and magnet steel 3, magnet steel seat 2 are installed in special-shaped sleeve 1, and magnet steel 3 is placed on the magnet steel seat 2, and rubber lever 6 is installed in insulating epoxy pipe 5 bottoms.
Operating procedure of the present invention is as follows: 1, connect earth terminal earlier, after connect conductor end, earthing device and insulating bar hold by magnetic, hook stick rotation, but lateral pin 12 corresponding bayonet sockets can block and the driven rotary earthing device; 2, the body 7 (its thread standard is decided according to the size of the existing most cable branch box double threaded screws that use) that will be threaded is enclosed within on the cable branch box double threaded screw, and rotating insulated action bars is tightened it, and promptly the earthing device front end connects.(general cable branch box double threaded screw has only two kinds of sizes, makes as required) 3, push away insulating bar and make spring shrink rotation one angle, make bearing pin 11 deviate from base 10 notches, the earth connection rear end begins stressed.Rotating insulated action bars makes intermediate plate 14, pad 15 and the body 7 that is threaded closely contacts with spiral shell spare 13 screw sockets, and promptly install firmly the earthing device rear end; 4, transfer to the insulating bar repetitive operation that three-phase is all connected, the earth connection installing finishes.
