Abstract

The utility model discloses a double-clamp wire clip mounted /dismounted without turnoff belonging to the electric metal device. The double-clamp wire clip mounted / dismounted without turnoff applies to the electric high-voltage overhead line and belongs to the connecting technical field of the drop wire of the transformer equipment. The utility model can solve the defect problem that because of the fracture of the clamping heads of the original product or the looseness the screw bolt of the original product, the accident can be caused. The utility model can improve the mechanical strength and the electric property. The shape and structure character of the utility model is that the utility model is formed by the main body structure combining with the accessory. The utility model comprises two parallel clamping heads. The opening direction of the two parallel clamping heads is opposite and a gap is arranged between the two parallel clamping heads. The utility model also comprises a drop wire clip at the lower part of a central wire. The essential technical characters of the utility model are that the original single clamping head shaping structure of the wire clamping part can be changed to the double-clamping head structure, which not only can make the utility model become an electric maintenance tool, but also the utility model can use a T-shaped wire clip so that the utility model can be used for the multiple use of the frequency operation of connecting wire, passing through wire, and grounding wire.

Description

Double-clamp wire clip mounted /dismounted without turnoff

The utility model belongs to electric armour clamp, can be used widely in power high voltage overhead transmission line, electric substation and downlead interconnection technique field, power station.

The original power gold utensil uses the charged mounted /dismounted wire clip of approved product (see Ministry of Water Resources and Power Industry's " electric armour clamp product sample " 85 years revised edition 124 pages) to be single dop structure for a long time, and the design is improved to novel pair of dop type structure.

The purpose of this utility model is to improve the high-voltage great-current lead is connected gold utensil with bus security reliability.

The purpose of this utility model is achieved in that and changes former single dop into two cards that downlead partly is positioned at two card centers.The dop that promptly blocks lead is two, and its bayonet socket direction one positive one is anti-, is 180 degree side by side.Tightly, except that main screw thread, increase by one again, use the helical pressure clamping wire tightly because of nut because of part adopts two helicitic textures.Downlead partly adopts aluminium gland U type nut fastening, and it is firm to reach line, the conduction excellent function.

This wire clamp main part adopts cast aluminium, aluminium alloy or other electric conducting materials to manufacture overall structure, and auxiliary adopts the steel nut.Processing request: the aluminum component surface should smooth, smooth, no sand holes, burr, basic size permissible variation are ± 1.0mm, and electric contact-making surface must be bright and clean, has good electric contact performance, and the wire clamp line outlet is the sliding bell mouth shape in garden, and nut adopts hot galvanizing.Make by oneself and be numbered that the promptly two cards of STJ(, T connect, wire clamp).

The utility model is manipulated simple and convenient: earlier the downlead line end is clipped fastening U type nut, moving screw is partly loosened, when lead or bus are positioned in the middle of the two-wire folder, revolve and turn 90 degrees, tighten double nut successively and get final product.Therefore, this utility model gets material, makes, manipulates and can both realize easily.

The utility model compared with prior art has the following advantages and good effect:

1, promptly belongs to electric armour clamp, can also rush to repair instrument as live line working, can make permanent wire clamp and substitute nut type T molded lines folder (the 77th page in 85 years revised editions of Ministry of Water Resources and Power Industry's " electric armour clamp product sample ", GB2340-85), can be suitable for again than frequent operation wiring, interim lead-in wire, the earth connection crossed, can be applicable to newly-built, reconstruction circuit, power failure or indirect, equipotential live line working multiple use.Can be fastening during use with common spanner, the charged indirect operating of available again insulating bar.

2, mechanical strength improves nearly one times, and stress distribution is even, does not come off the security reliability height.Original product can cause the accident as the dop fracture takes place, and new product as a dop fracture after, still can continue operation.

Fastening part adopts two screw threads for fastening, and long-time running is not released.

Downlead is positioned at the wire clamp center of gravity, two card symmetries, stable equilibrium.

3, wire clamp and lead contact area double, and resistance reduces, and electric property is good.

For realizing this wire clamp better, product has serial model No., to be suitable for lead, the bus of Different Diameter level.

Concrete structure of the present utility model will clearer explanation in following enforcement accompanying drawing.

This wire clamp comprises two dop parts (1) and (2), and is gapped between two dops though the identical bayonet socket opening direction of its structure is opposite, and downlead wire clamp (3) is positioned at two card center line bottoms.(4) be the dop movable contact, (5) are the galvanized steel nut, and (6) are clamp nut, this gold utensil by agent structure and annex in conjunction with forming.

Claims

1, two cassette tape Densos unload wire clamp and belong to electric armour clamp, be applied to power high voltage overhead transmission line, electric substation and downlead interconnection technique field, power station, this wire clamp is made up of agent structure and annex, comprise two dop parts (1) and (2), and downlead wire clamp (3), the opening direction that it is characterized in that two dops is opposite, leaves the gap between two dops.

2, device according to claim 1 is characterized in that having in the dop movable contact (4), compresses lead by galvanized steel bolt (5), and has clamp nut (6) to prevent to release.

3, device according to claim 1 is characterized in that the card conductor part is side by side two dops, and dop opening direction one positive is anti-, and its opening direction difference angle is 180 degree.
