Description

Live insulating clothing detection device

technical field

The utility model relates to a detection device for live insulating clothes, which belongs to the field of electric power application.

Background technique

At present, the detection method we use is to use a special detection fork connected to the insulation shaker to move up and down, left and right on the insulation clothing. When the insulation shaker indicates zero, it is judged that the insulation is damaged, the leak detection speed is slow, and the leak detection accuracy is poor. And it can only be detected when the overall insulation of the insulating clothing is reduced or there are penetrating defects, and the damage to a certain point on the insulating clothing cannot be detected. Therefore, this detection method and means cannot accurately detect the real defects of the insulating clothing.

The technical scheme of the utility model is as follows:

The detection device for live work clothing includes a voltage regulator, a step-up transformer, a hanger and a detector. The voltage regulator and the step-up transformer form a power supply. The hanger is a positive electrode, and the detector is a negative electrode. The outer surface of the stainless steel skeleton is wrapped with conductive The cloth constitutes a clothes hanger, the clothes hanger is electrically connected with the step-up transformer and the voltage regulator in sequence, and the detector is grounded and corresponds to the clothes hanger.

The conductive cloth is filled with a hard sponge layer.

The bottom end of the clothes hanger is connected with an insulating board.

The skeleton is configured in the shape of a human body.

The detector is connected with a display instrument, and the display instrument includes an ammeter, an overcurrent protection circuit, an indicator light and a grounding device.

detailed description

Example

As shown in the figure, the detection device for live work clothing includes a voltage regulator 1, a step-up transformer 2, a clothes hanger 3 and a detector 5. The voltage regulator 1 and the step-up transformer 2 form a power supply, and the clothes hanger 3 is a positive electrode. 5 is a negative electrode, made of stainless steel into a skeleton in the shape of a human body, the outer surface of the skeleton is wrapped with conductive cloth to form a hanger 3, the conductive cloth is filled with a hard sponge layer, the bottom of the hanger 3 is connected with an insulating plate 4, and the hanger 3 is connected to the step-up transformer 2. The voltage regulator 1 is electrically connected sequentially, and the detector 5 is grounded and corresponds to the clothes hanger. The detector is composed of a metal plate connected to an insulating rod; the metal plate is rectangular, 20 cm long; 15 cm wide; and 0.15 cm thick; the insulating rod is a hollow insulating rod with a diameter of 3 cm, and the length of the insulating rod is 450 cm. The detector is connected with a display instrument 6, and the display instrument includes an ammeter, an overcurrent protection circuit, an indicator light and a grounding device.

The insulating suit is put on the hanger, and the detector walks up and down, left and right on the insulating suit to complete the test. When a certain part of the insulating suit is damaged and a leakage occurs, the display will give an audible and visual alarm and display on the display. The value of the breakdown current.

The parameters of each part of the utility model are as follows:

1. Voltage regulator: range is 0-250V, capacity is 3kVA;

2. Step-up transformer: 50000/200, with a capacity of 3kVA;

3. The insulation board can effectively insulate 100kV;

4. The clothes hanger is a high-voltage part. When testing the insulating clothing, a voltage of 30kV is provided;

5. The detector is grounded through the ammeter of the display instrument, and the current limiting resistance is 100Ω;

6. Display instrument, composed of ammeter, overcurrent protection, indicator light and grounding;

The concrete process of the utility model test is as follows:

The 59# rod pin insulator of a trunk line fell off, and the insulator was replaced by live work. After arranging safety measures, test the insulating clothing for live work. The insulating suit is first worn on a hanger, then energized and pressurized. When the grounded detector is used for insulation detection, the clothes hanger and the grounded detector will discharge, and at the same time, the power switch protection will operate. When the insulation clothing was checked after the power was cut off, it was found that there was a pinhole-sized discharge point at the connection between the armpit sleeves and the ribs of the insulation clothing. The reason for the damage of the insulating clothing is that the underarms are often worn, and the connection between the sleeves and the ribs is not tight. By using the device, a potential safety hazard is effectively avoided, and the occurrence of personal injury is avoided.
