Abstract
The invention relates to an aerodynamic disc-shaped suspending type glass insulator replacing clamp which is suitable for operation of professionally replacing and adding a large-edge glass insulator under a live-working condition in the process of electricity transmission. According to the structure, the aerodynamic disc-shaped suspending type glass insulator replacing clamp is characterized in that a fixing girder is arranged between screw rods, a fastener is arranged on the fixing girder, and a socket clamp is connected with the lower portions of the screw rods. According to the aerodynamic disc-shaped suspending type glass insulator replacing clamp, the large-edge glass insulator can be replaced easily, the socket clamp is installed on angle iron arranged above a hanging point, ground electric potential operation is conducted by an operator, the operation is conducted in a position away from a strong electric field, safety of live-working is improved to a great extent, working intensity of the operator is reduced, operation cost is reduced, advantages are provided to the performance of the live-working, defect elimination can be conducted on the ground electric potential operation in time, safe and stable operation of a power network is guaranteed, reliability of power distribution of an electric transmission line is effectively improved and the aerodynamic disc-shaped suspending type glass insulator replacing clamp can be popularized and used in the professional electricity transmission and production easily.
Description
Technical field
The present invention relates to a kind of insulator and change instrument, relate in particular to a kind of aerodynamic type plate-shaped suspension type glass insulator and change jig, the professional charged for replacement that is suitable for transmitting electricity, increase are greatly along the glass insulation subjob.
Background technology
The combination of 220kV circuit straight line string insulation at present mostly is greatly, the cross-arm end be 1 greatly along glass insulator, the lower end is synthetic insulator, because circuit is struck by lightning, cause lowly along the glass insulator insulation values greatly, there is the flashover vestige on the surface, is not suitable for reruning and next lightning fault point is searched.In addition in order to improve the line insulation level, the former just synthetic insulator of part, also progressively increasing greatly along glass insulator at present, change or increase but can only have a power failure mostly in the prior art.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of aerodynamic type plate-shaped suspension type glass insulator to change jig, solved that the operating personnel must directly promote the problem that lead could shift load in the prior art.
Technical scheme of the present invention is as follows:
Be provided with built-in beam between the leading screw, built-in beam is provided with securing member, and the bottom of leading screw is connected with a bowl jig.
Described securing member is steady pin or protection clamping plate.
Described steady pin is fixed on the angle bar by wing screw.
Described protection clamping plate are 4 V-type plates.
A described bowl jig employing draw-in groove and wing screw are fastening.
A described bowl jig and insulator bowl head are complementary.
Described leading screw is provided with the leading screw spanner.
Advantageous effect of the present invention is as follows:
Be very easy to along glass insulator changing greatly, jig is installed on the angle bar of hanging point top, and the current potential operation of operating personnel possession is operated away from highfield, increase substantially the fail safe of live line working, alleviate operating personnel's labour intensity, reduce operating cost, provide advantage for carrying out live line working, can in time carry out earth potential working disappears scarce, guarantee power network safety operation, improved the transmission line power supply reliability effectively, be easy to promote the use of in transmission of electricity production specialty.
