Embodiment

[0017] Such as figure 1 As shown in the figure, double insulating plates are used as the main rod, and the main rod connects the shear head and the linkage part; the shear head adopts a mechanical ratchet shear head. The linkage part includes a force arm, a pull rod and an operating handle, one end of the force arm is connected with the cutting head, the force arm is connected with the pull rod, and the operation handle is connected with the pull rod and the main rod.

[0018] During operation, the operator sends the broken thread to the position to be cut, the cutting head holds the wire, repeatedly pulls the operating handle, the cutting head uses gear transmission to make the upper and lower teeth align, and cuts the wire.

Abstract

The invention relates to a 10kv insulating bolt cutter. The structure of the cutter is characterized in that a main lever is connected with a shear head and a linkage part, and the shear head adopts the mechanical ratchet shear head. The bolt cutter provided by the invention can perform zero-load lead shearing work for a lead with the cross section less than 240mm<2> on the 10kv line. According to the invention, the work time is shortened, the work can be done without cutting off a power supply, the reliability for supplying electricity is greatly improved, the work intensity of operators is obviously reduced, and the safety and the reliability are ensured; the live working level on the line is improved, so as to greatly facilitate the safe production of power enterprises; and the bolt cutter is simple in structure and safe and reliable, has strong practical applicability, and can be applied to multiple telegraph poles with the 10kv line, thereby having great value in popularization and application.

Description

technical field [0001] The invention relates to a disconnecting shear, in particular to a 10kv insulating disconnecting shear, which is mainly used for disconnecting leads of lines and branch lines without load, and belongs to the field of electric power applications. Background technique [0002] In order to meet the requirements of the rapid development of the local economy, the power supply companies have transformed the urban network and promoted the use of 10kV insulated wires to replace the bare aluminum wires in the original 10kV lines. After the transformation of the urban network, the diameter of the original 10kV line conductors generally increased. [0003] At the same time, in order to provide better services to users, provide high-quality and reliable power supply, and complete the power supply reliability index, live work has been widely carried out in 10kV lines in recent years, such as live disconnection and connection, and the live work used in live work Th...
