Abstract
In order to solve the problem that an overhead transmission line angle support exterior angle ground line is not easy to hang and overcome the disadvantage of an original insulation rope cooperation hook mode, the utility model provides an overhead transmission line angle support exterior angle ground line hanging device which comprises a ground line hanging support and a rod type electroscope. The ground line hanging support is a L-shaped insulating rod, wherein the inner of one end of the rod is provided with a female thread which can be cooperated with a male thread at a tip of a rod type electroscope insulator spindle; the ground line hanging support and the rod type electroscope are in fixed connection with the male thread through the female thread. The hanging device of the utility model utilizes insulating properties and telescoping function of the rod type electroscope and installs an auxiliary device on the top of the electroscope; the auxiliary device can be freely detached to hang an angle support exterior angle ground line.
Description
Technical field
The utility model belongs to power domain, provides a kind of overhead transmission line strain tower exterior angle earth connection to throw to mount especially and puts.
Background technology
The earth connection at overhead transmission line strain tower exterior angle is thrown and is hung, perplexing the employee of a line production unit always, under the normal condition strain tower drainage lead sag minimum point should with the cross-arm head in same perpendicular, because the operating personnel can arrive the cross-arm head, the conductor wire end of earth connection is easy to throw and hangs on the drainage lead, but the plane that angle tower cross-arm head becomes with drainage lead sag minimum point becomes 30 to 60 degree angles with plumb line, increased throwing hanging earthing conductor difficulty greatly, at present in a line power failure operation, throwing extension C phase earth connection needed about 10 minutes times spent, and this greatly reduces operating efficiency.
The method that we taked in the past is, utilizes one to thoroughly do away with the edge rope, ties up an operation hook on the fag end.Utilize hook to hook the drainage lead, it is pulled to the at arm's length position of human body directly throws extension, do 2 harms like this: 1. the drainage lead can generation deformation cause the broken lot heating under the effect of external force.2. drainage conductor spacing human body is nearer, can form injury to human body as unexpected incoming call.
Summary of the invention
Be difficult for throwing the problem of hanging in order to solve overhead transmission line strain tower exterior angle earth connection, overcome the shortcoming that original use insulation rope cooperates hook mode, the utility model provides a kind of overhead transmission line strain tower exterior angle earth connection to throw to mount and has put, this throwing mounts to put and utilizes the galvanoscopic insulating properties of bar type and Telescopic, on the electroscope top one servicing unit is installed, and this device can freely be dismantled, and is used for carrying out the throwing extension of strain tower exterior angle earth connection.
The utility model specifically provides a kind of overhead transmission line strain tower exterior angle earth connection to throw to mount and has put, and it is characterized in that: comprise that earth connection hangs support 1 and bar type electroscope 3; Wherein, it is a L type insulating rod that earth connection hangs support 1, be provided with internal thread 2.1 in the one end termination of its stock, internal thread 2.1 can cooperate with the external screw thread 2.2 that is positioned at bar type electroscope 3 insulating bar terminations, and earth connection hangs support 1 and is fastenedly connected by internal thread 2.1 and external screw thread 2.2 with bar type electroscope 3.
Overhead transmission line strain tower described in the utility model exterior angle earth connection is thrown to mount and is put, and it is characterized in that: described earth connection hangs support 1 its stock does not have the end of internal thread to have spherical structure.
Overhead transmission line strain tower described in the utility model exterior angle earth connection is thrown to mount and put, and it is characterized in that: described bar type electroscope 3 is the more piece bar type structure.
The utility model provides, and overhead transmission line strain tower exterior angle earth connection throws to hang to throw to mount puts, and solves for a long time strain tower exterior angle earth connection and is difficult for throwing the problem of hanging and gives the transmission of electricity puzzlement that professional worker at the production line brings, thereby improved operating efficiency greatly.
