Abstract

The utility model provides a charged fastener which can realize fastening of bolts under the condition that equipment is charged and the human body is in ground potential. According to the technical scheme, the charged fastener is characterized by comprising a connector, a transition piece and a sleeve spanner which are sequentially connected, wherein the connector is matched and connected with an insulated rod, the connector is a circular thin plate, and a plurality of lugs are arranged along the circumferential direction; and the transition piece has a hollow structure.

Description

The tight device in charged school
Technical field
The utility model relates to the transmission facility technical field, particularly a kind of for keeping in repair the device of transmission facility, is specifically related to a kind of for tightening the tight device in charged school of converting equipment bolt.
Background technology
Overhead power transmission equipment and converting equipment, under natural environment, the impact of conducting bolt wind-engaging pendular oscillation easily occurs loosening for a long time, can cause the heating of current-carrying part overcurrent even to cause the generation of power transmission and transforming equipment broken string accident.
Eliminate at present this type of defect and adopt power failure operation or equal potential working.Power failure operation program complexity, affect power supply reliability and economic loss arranged; Equal potential working is in the equipment live situation, bolt on power equipment is carried out to school tight, and, there is potential safety hazard in inconvenient operation.
The utility model content
The purpose of this utility model is to provide the tight device in a kind of charged school, can be at equipment live, and the person, in the earth potential situation, is realized the fastening of bolt.
To achieve these goals, the utility model is by the following technical solutions:
The tight device in a kind of charged school is characterized in that: comprise the connector, transition piece and the box spanner that connect successively, connector is for being connected with insulating bar, and connector is circular sheet, and along the circumferential direction is provided with a plurality of projections; Transition piece is hollow structure.
Further, have the U-shaped breach on connector.
Further, box spanner one end and transition piece are welded as a whole.
Further, connector and transition piece are welded as a whole.
Further, projection is rectangular configuration.
The beneficial effects of the utility model:
Adopt said structure, change earth potential working into, avoided personnel's equal potential working, there is no the danger of live line working, reduced labour intensity.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure 1, connector, 2, projection, 3, transition piece, 4, sleeve barrel spanner, 5, the U-shaped breach.
Embodiment
Better understand the utility model for the ease of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further details, following explanation is only exemplary.
With reference to accompanying drawing 1, the tight device in a kind of charged school, comprise the connector 1, transition piece 3 and the box spanner 4 that connect successively, connector 1 is for being connected with insulating bar, connector 1 is circular sheet, has U-shaped breach 5 on connector 1, and along the circumferential direction is provided with a plurality of projections 3; Transition piece 3 is hollow structure.
Consider that manufacture is easy to process, box spanner 4 one ends and transition piece 3 are welded as a whole, and connector 1 is welded as a whole with transition piece 3.
In the present embodiment, projection 2 is rectangular configuration.
When the maintenance personal uses the utility model, connector 1, with after insulating bar is connected, can carry out fastening to bolt by box spanner 4.
Above embodiment is only for illustrating that the technical solution of the utility model is not intended to limit; those skilled in the art should modify or the part technical characterictic is equal to replacement with reference to foregoing description; but under the spirit that does not break away from technical solutions of the utility model, above-mentioned change or be equal in the technical scheme scope that replacement should belong to the utility model protection.
