Problems solved by technology

[0002] In the existing power grid structure, the line can only be branched by installing a single-phase or three-phase isolating switch on the cross-arm of the utility pole, which occupies a small space on the top of the utility pole; and for the middle section of the line due to maintenance or temporary wiring The temporary disconnection problem encountered can only be paralleled through the parallel ditch line clamp, and the bucket arm truck can be used to come to the temporary branch line, and it is not convenient to branch the line in the middle of the line

Abstract

The invention discloses a circuit disconnecting switch which comprises a left wiring terminal, an insulator, a conductive knife and a right wiring terminal. The left wiring terminal and the right wiring terminal are fixed at two ends of the insulator respectively, one end of the conductive knife is movably arranged at the left wiring terminal, and the other end of the conductive knife is provided with a hook and connected with the right wiring terminal through the hook. According to the circuit disconnecting switch, two ends are directly connected with wires, cross arm space of wire poles is not occupied, the circuit disconnecting switch can be conveniently mounted at a circuit terminal or any position in the middle, and all-tension connection is provided.

Description

technical field [0001] The invention relates to the field of wire and cable connection, in particular to a line isolation switch for connecting wires. Background technique [0002] In the existing power grid structure, the line can only be branched by installing a single-phase or three-phase isolating switch on the cross-arm of the utility pole, which occupies a small space on the top of the utility pole; and for the middle section of the line due to maintenance or temporary wiring The temporary disconnection problem encountered can only be paralleled through the parallel ditch line clamp, and the bucket arm truck can be used to temporarily branch the line, and it is impossible to conveniently branch the line in the middle of the line. Contents of the invention [0003] The purpose of the present invention is to provide a line isolating switch, both ends of which are directly connected to the wires, do not occupy the space of the cross-arm of the utility pole, can be conve...
