Abstract
Provided is a grounding wire for a cable distribution box or a ring main unit. The technical scheme is that the grounding wire comprises an elbow-type cable plug, a high-voltage cable and a grounding electrode, wherein one end of the high-voltage cable is connected with the tail part of the elbow-type cable plug, the other end of the high-voltage cable is connected with the grounding electrode, and the head part of the elbow-type cable plug is connected in a plugged mode with a single-pass sleeve joint of a power wire of a cable distribution box or a ring main unit. By using the elbow-type cable plug to introduce the grounding wire to the single-pass sleeve joint of the power wire of the cable distribution box or the ring main unit, the problem that the cable distribution box or the ring main unit cannot be separately grounded is solved, condition is created for small-range power outage during maintenance of the cable distribution box or the ring main unit, and safety of a power outage site is ensured.
Description
Technical field
The utility model relates to a kind of earth connection that uses in cable distribution box, ring main unit maintenance process, belongs to the power transmission and distribution technical field.
Background technology
Cable distribution box, ring main unit are the visual plants in urban power distribution network, when cable distribution box and ring main unit are overhauled, and except the need deenergization, also will be with its internal wiring ground connection, to guarantee maintainer's personal safety.But because cable distribution box and ring main unit are full-closed structure, earth connection on common distribution line can't be applied on these two kinds of equipment, can only be with ground connection after the outage of whole piece circuit while therefore overhauling cable distribution box and ring main unit at present, so not only enlarged power failure range, bring inconvenience for more user, and can't effectively get rid of potential safety hazard.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of earth connection for cable distribution box or ring main unit is provided, to solve the independent grounding problem in cable distribution box and ring main unit maintenance process.
Problem described in the utility model is realized by following technical scheme:
A kind of earth connection for cable distribution box or ring main unit, formation comprises elbow type cable plug, high-tension cable and earth electrode, one end of described high-tension cable is connected with the afterbody of elbow type cable plug, one end is connected with earth electrode, and the single path sleeve joint of the head of described elbow type cable plug and the power line of cable distribution box or ring main unit is pegged graft.
Above-mentioned earth connection for cable distribution box or ring main unit, described high-tension cable adopt 10KV-50mm2 high pressure copper cable.
The utility model utilizes elbow type cable plug with the single path sleeve joint of ground wire lead-in cable distribution box or ring main unit power line, solved well the problem that cable distribution box, ring main unit can not independent groundings,, for condition has been created in the power failure among a small circle in cable distribution box, ring main unit maintenance process, also guaranteed to have a power failure on-the-spot fail safe simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure, each list of reference numerals is: 1, earth electrode; 2, high-tension cable; 3, elbow type cable plug.
Embodiment
Referring to Fig. 1, the utility model consists of earth electrode 1, high-tension cable 2 and elbow type cable plug 3, high-tension cable 2 adopts 10KV-50mm2 high pressure copper cable, the single path sleeve joint of the head of elbow type cable plug 3 and the power line of cable distribution box or ring main unit is pegged graft, afterbody and high-tension cable 2 crimping, install the extinguishing arc conducting rod finally.This earth connection utilizes the action bars operation, and is own low weight because of elbow type cable plug 3,, so operation is very flexible, facilitates.The utility model is applicable to 10KV plug-in cable distribution box, ring main unit, and the power failure range in the time of can greatly dwindling maintenance, create huge economic benefit.When cable distribution box or ring main unit passed through the utility model ground connection, earth connection was very clear, meets the safety regulations requirement, had greatly increased the on-the-spot coefficient of safety that has a power failure.
Operating procedure: when maintenance cable distribution box or ring main unit, at first power line is extracted from the single path sleeve joint of cable distribution box or ring main unit, make cable distribution box or ring main unit outage, then elbow type cable plug 3 of the present utility model is inserted the single path sleeve joint of cable distribution box or ring main unit, and, with earth electrode 1 reliable ground, just can carry out maintenance activity afterwards.
Claims (2)
1. earth connection that is used for cable distribution box or ring main unit, it is characterized in that, it comprises elbow type cable plug (3), high-tension cable (2) and earth electrode (1), one end of described high-tension cable (2) is connected with the afterbody of elbow type cable plug (3), one end is connected with earth electrode (1), and the single path sleeve joint of the head of described elbow type cable plug (3) and the power line of cable distribution box or ring main unit is pegged graft.
