Problems solved by technology

[0005] At present, there is a technical difficulty in carrying out the work of replacing the isolating switch with load by the insulating rod method: when replacing the middle-phase isolating switch, because the operator is between two phases when removing the isolating switch, the working space is narrow, and there is no special shelter The appliance insulates and shields the two-phase lead wires, and the operator is likely to have insufficient safety distance from the live body or even directly touch the live body when working, thus causing electric shock hazards

Abstract

The invention relates to an insulating shielding plate, and the insulating shielding plate is widely applied to the work of the replacement of an isolated phase switch in the load replacement of an overhead distribution line through an insulating rod method, and belongs to the technical field of distribution line live-line maintenance sites. An insulating partition plate is concave, and a hook body I and a hook body II are respectively arranged at the two ends of the top of the insulating partition plate. A connector is arranged at the upper part of the insulating partition plate and is located in the middle of the insulating partition plate in the length direction, and a handle groove is formed above the insulating partition plate and is positioned right above the connector. The insulating shielding plate is simple in structure, convenient to install, safe and reliable, wide in application range and capable of improving hot-line work efficiency.

Description

technical field [0001] The invention relates to an insulating shielding plate, which is widely used in the on-load replacement of intermediate-phase isolating switches by means of insulating rods for overhead power distribution lines, and belongs to the technical field of on-site maintenance of power distribution lines. Background technique [0002] The isolating switch is a switchgear without an arc extinguishing device commonly used on power distribution overhead lines. It has an obvious disconnection point when opening to ensure the safety of other electrical equipment; Load current and short circuit fault current. Due to insulation aging, external force damage, service life and other reasons, it is necessary to frequently replace the isolating switch. [0003] Replacing isolating switches in a power outage needs to interrupt the power supply in a certain area, which affects the normal production and life of a large number of users and reduces the reliability of power su...
