Problems solved by technology

[0003] Due to the partial discharge of the existing cables, the temperature of the wires rises, so it is necessary to detect the cables. In order to realize that the device can automatically walk on the cables, the current solution is to squeeze the cable skin through the friction wheel, and drive the device Moving forward, but the friction wheel is easy to slip, which makes it inconvenient to determine the position of the node where the cable has problems

Abstract

The invention provides a safety detection device for power distribution, which relates to the field of power distribution detection. The safety detection device for power distribution includes a front traveling mechanism and a rear traveling mechanism. The front traveling mechanism and the rear traveling mechanism are slidably connected, and the front traveling mechanism and the rear traveling mechanism are fixedly connected by a compression spring. A power mechanism is fixedly installed on the front side of the lower end, the power mechanism is engaged with the front traveling mechanism, and a fixed wheel is fixedly installed on the inner upper ends of the front traveling mechanism and the rear traveling mechanism. The safety detection device for power distribution can be fixed to the cable through the periodic front traveling mechanism and the rear traveling mechanism, and the front traveling mechanism is pushed forward by the power mechanism and the rear traveling mechanism is pulled forward by the compression spring, so that it can move forward. The inspection of the cable can be achieved in a state of no slippage, and the problem that the problem node is difficult to find caused by the repeated detection of the same position of the detection point caused by the slippage of the friction wheel in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of power distribution detection, in particular to a safety detection device for power distribution. Background technique [0002] Discharge that occurs locally in the insulation of electrical equipment under the action of a sufficiently strong electric field. This discharge is limited to only causing a partial short (bridge) of the insulation between the conductors without forming a conductive path. Every partial discharge has some effect on the insulating medium. [0003] In the existing cable, the temperature of the wire increases due to the partial discharge of the wire, so it is necessary to detect the cable. In order to realize that the device can automatically walk on the cable, the current solution is to squeeze the cable skin through the friction wheel to drive the device. Go forward, but the friction wheel is easy to slip, which makes it inconvenient to determine the position of the node where the...
