Windowless ring main unit internal contact temperature inspection device

Abstract

The invention discloses a windowless ring main unit internal contact temperature inspection device, which comprises a temperature detection device, a dismounting mechanism is arranged on the rear surface of the temperature detection device, and a clamping mechanism is fixed on the rear surface of the dismounting mechanism. When the device is arranged in a mounting area in a sleeving manner, firstly, two arc-shaped plates are pressed, second clamping blocks are driven to move inwards when the arc-shaped plates move, and the second clamping blocks are clamped between different first clamping blocks, so that the length of a connecting belt sliding to the interior of an adjusting shell is achieved, and an adjusting plate is driven to move up and down by pressing a disc; the second clamping block stops limiting the first clamping block, the length of the part, sliding out of the adjusting shell, of the connecting belt is conveniently adjusted, then an arc-shaped plate is driven by a thrust spring to move, the second clamping block continues to be clamped with the first clamping block, and then overall length adjustment of the device is achieved; therefore, the electric power pipelines with different diameters and widths can be sleeved for installation.

Description

technical field [0001] The invention relates to the technical field of power distribution inspection, in particular to an inspection device for contact temperature inside a windowless ring network cabinet. Background technique [0002] The ring network cabinet is a group of high-voltage switchgear installed in the steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, low price, and It has the advantages of improving power supply parameters and performance and power supply security. A closed ring is formed through the power supply trunk line. The power distribution branch can get power from its left main line and its right main line. When the left main line fails, it will continue to receive power from the right main line. If there is a fault, it will continue to receive power from the main line on the left. In this way, although the total power supply is a s...

Problems solved by technology

[0005] The purpose of the present invention is to provide a temperature inspection device for the internal contacts of the windowless ring network cabinet to solve the problem that the power ring network cabinet proposed in the above background technology cannot be opened frequently due to its special reasons, and the temperature of each contact inside it is patrolling. For the vast majority of cabinets without test windows, the inspection work is basically difficult to carry out. Even for cabinets with test windows, due to the limited size of the window and the use conditions of the infrared instrument, the use of The problem that the temperature value of the internal contacts still cannot be accurately grasped during infrared scanning temperature measurement
