Description

A kind of supporting insulator earthing device of distribution transforming maintenance
[technical field]
The utility model relates to the supporting insulator earthing device of a kind of distribution transforming maintenance, belongs to electric power system Special safety apparatus technical field.
[background technology]
When basic routing line does not have a power failure, need to hang earth connection for carrying out distribution transforming upkeep operation, earth connection was originally directly be hung on to be on the lead-in wire of naked state, this lead-in wire upper, lower end respectively with pile crown under the wiring of drop out fuse, distribution transforming device high-voltage pile connects, due to hang dismounting ground wire time drop out fuse wiring under pile crown, lead-in wire and distribution transforming device high-voltage pile all stressed, easily cause lead-in wire lax, and pile crown under the wiring of drop out fuse, distribution transforming device high-voltage pile is impaired, affect safety, in addition, phase spacing due to drop out fuse has certain designing requirement, operating space when hanging dismounting ground wire operation is too near apart from charged position, there is safe distance deficiency, the life security of distribution transforming maintainer is constituted a threat to, and along with the propelling of overhead transmission line insulating work, lead-in wire changes insulator pin into, therefore, how hanging earth connection and being hung on where is the new problem that distribution transforming maintainer faces.
[utility model content]
The purpose of this utility model is to provide a kind of for hanging the supporting insulator earthing device disconnecting the high distribution transforming maintenance of ground processing safety, stressed by guaranteeing neither to increase insulator pin after hanging dismounting ground wire on the apparatus, the connection pile crown not increasing again upper and lower two ends of insulator pin is stressed.
For reaching above-mentioned purpose, the utility model provides following technical scheme:
The supporting insulator earthing device of distribution transforming maintenance, comprise insulator pin, supporting insulator, right angle rack, insulator pin upper, lower end respectively with drop out fuse, the high-voltage pile of distribution transformer is connected, drop out fuse, the upper end of right angle rack is individually fixed on upper holder, supporting insulator is placed on the hypomere of right angle rack, its improvement is: also comprise special-shaped wire clamp and ground loop, abnormity wire clamp is respectively arranged with the wire diameter with insulator pin, the clamp groove that the wire diameter of ground loop is suitable and annular groove, described ground loop, insulator pin is all clamping fixed by special-shaped line, special-shaped line folder is fixedly connected on the hypomere of right angle rack, one end and the right angle rack of supporting insulator are inconsistent, its other end is then inconsistent with special-shaped wire clamp.
Above-mentioned supporting insulator is silicon rubber supporting insulator.
The intensity of silicon rubber supporting insulator is good, and not fragile, durability is good.
Above-mentioned ground loop is in side's annular.
Above-mentioned drop out fuse is alternate is furnished with three, and right angle rack interval is furnished with three, and supporting insulator has three, and special-shaped line accompanies three, and ground loop has three, and insulator pin has three.
Compared with prior art, the utility model tool has the following advantages and beneficial effect:
Increase between drop out fuse and the high-voltage pile of transformer and have right angle rack, and the hypomere of right angle rack has installed supporting insulator, special-shaped wire clamp successively, abnormity wire clamp is fixed for insulator pin, ground loop, due to ground loop and drop out fuse and all have certain safe distance with the high-voltage pile of transformer, seem when therefore hanging dismounting ground wire operation at ground loop place safety, and the life security of distribution transforming maintainer obtains guarantee; Because insulator pin and ground loop separate independently to be fixed on special-shaped wire clamp, when therefore hanging dismounting ground wire on ground loop, under the wiring of insulator pin, drop out fuse, the high-voltage pile of pile crown and distribution transformer is all without the need to stressed, eliminate pile crown under the wiring of drop out fuse, the high-voltage pile of distribution transforming device loosens and even impaired hidden danger, there will not be the relaxation causing insulator pin because hanging dismounting ground wire, being conducive to distribution transformer long-term stability and running.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
[embodiment]
Please refer to Fig. 1, shown in 2, the supporting insulator earthing device of distribution transforming maintenance, comprise insulator pin 5, supporting insulator 4, right angle rack 3, abnormity wire clamp 6 and ground loop 7, insulator pin 5 upper, lower end respectively with drop out fuse 1, the high-voltage pile 20 of distribution transformer 2 is connected, drop out fuse 1, the upper end of right angle rack 3 is individually fixed on upper holder 91, the hypomere of right angle rack 3 is nested with supporting insulator 4 successively, abnormity wire clamp 6, and fixed with screw S, one end and the right angle rack 3 of supporting insulator 4 are inconsistent, its other end is then inconsistent with special-shaped wire clamp 6, abnormity wire clamp 6 is respectively arranged with the wire diameter with insulator pin 5, the clamp groove 61 that the wire diameter of ground loop 7 is suitable and annular groove 62, ground loop 7, insulator pin 5 is all fixed by special-shaped wire clamp 6.
