Description

Rolling insulation detection device

technical field

The invention relates to the field of detection devices for electrical faults, in particular to a rolling insulation detection device.

Background technique

Before live work, it is necessary to perform insulation testing on the insulating tools used. The tools that need to be tested include insulating rods, insulating ropes, etc. At present, there is no electrode capable of detecting the full length of insulating rods and insulating ropes.

The currently used insulation detection device can only perform point measurement, usually using a point measurement insulation detection electrode, which is a metal electrode with a width of two centimeters and a gap of two centimeters between the poles. In order to prevent the insulated electrodes from scratching the detected tool during use, the sliding method cannot be used to detect the tool, and only the method of point measurement can be used, which leads to the fact that the entire length of the detected tool cannot be covered during the detection, but can only be selected by sampling. Click to check. This detection method cannot guarantee timely detection of insulation defects of tools.

In practical applications, insulating rods and insulating ropes are often only partially insulated. Since they can only be detected by point measurement, even if the number of point measurements is large, it is difficult to accurately find the location of insulation failure. Great security risk.

In order to achieve the above object, the rolling insulation detection device of the present invention includes a roller electrode, an insulating side plate, and an insulating handle. The front and rear roller electrodes can be rotatably fixed between two parallel insulating side plates, and the insulating handle is hollow. The structure is fixed in the middle of the insulating side plate, and the wire passes through the insulating handle and the roller electrode to realize electrical conduction.

Further, the roller electrode is connected to the insulating side plate through a rotating shaft, and a bearing is also arranged on the rotating shaft.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figures 1 and 2, the rolling insulation detection device of the present invention includes a roller electrode 1, an insulating side plate 2, and an insulating handle 3. The roller electrode is made of metal, and the two roller electrodes are arranged in parallel front and back, and both pass through the rotating shaft 4 It is rotatably fixed between two parallel insulating side plates, and a bearing is provided on the rotating shaft; the roller electrode is hourglass-shaped, and the center is sunken inwards. This shape allows the roller electrode to fit insulating rods or insulating ropes of different diameters. Increase the contact area between the roller electrode and the insulating rod or insulating rope; you can further cover the outer surface of the roller electrode with high-density conductive sponge. The conductive sponge has the characteristics of long conductive period and is not affected by temperature and humidity. The contact area of the rod or insulating rope.

In addition to the two parallel insulating side plates used to fix the roller electrodes, an insulating cover plate 5 can be further added above the two insulating side plates. The two ends of the insulating cover plate are vertically connected with the two insulating side plates respectively. and insulating side panels can cover most of the exposed metal to prevent operators from being shocked by accidental touch during operation;

The insulating handle has a hollow structure and is fixed in the middle of the insulating side plate. The wire 6 passes through the insulating handle and the insulating side plate and is fixed on the rotating shaft through the terminal 7 to realize electrical conduction with the roller electrode; the terminal can be fixed on the outside or inside of the insulating plate. On the rotating shaft, from the perspective of convenient operation, it is more appropriate to fix the terminals on the outside of the insulating plate. In this case, it is necessary to cover the rotating shaft, the nuts at both ends and the connecting terminals with an insulating layer to prevent the operator from making mistakes during the operation. Get an electric shock if you touch it.

When in use, the operator connects the rolling insulation detection device of the present invention with the insulation resistance detector, holds the insulation handle, presses the roller electrode on the surface of the insulation rod or insulation rope, and rolls slowly along the surface, and the insulation resistance is indicated by observing the insulation resistance.
