Direct sales of voltage withstand test device for insulated boots and glovesIt is mainly used for conducting power frequency withstand voltage tests on safety tools such as insulated gloves and boots, in order to determine whether these tools meet the usage conditions and ensure the personal safety of workers.

Technical indicators:

Electrode: ф 3mm steel ball

Test voltage: AC 0-50Kv DC 0-60KV

Test current: 0-60mA

Current measurement accuracy: 0.2 level

Voltage measurement accuracy: 0.2 level

Large experimental quantity: 3 pairs/6 pieces, 6-channel current detection

Power supply: AC220V ± 10%

working principle:

Connect the power supply of 0~220V, adjust the power frequency withstand voltage test bench, and according to the electromagnetic induction principle of the test transformer, generate a power frequency high voltage of 0~30KV from the transformer to each electrode, so that the insulation boots (gloves) can obtain the specified test voltage. According to the testing procedure for insulated boots (gloves), read and record the test parameters.

Experimental steps:

1. Add two-thirds of the water into the sink and fix it on an insulated countertop.

2. Place the insulated boots and gloves with added water into the sink, and clamp the insulated gloves with the insulation clip on the probe. The upper opening of the insulated boots and gloves should not get wet and should be kept dry.

3. Adjust the tension on the high-voltage pipe, insert the probe into the water inside the insulated boots and gloves, and tighten the tension to secure the probe.

4. Connect the sink box to the ground, connect the sink box socket to the control box output socket, and turn each milliampere meter switch on the sink box to the 'off' position.

5. Connect the power socket of the control box to a 220V power supply and ground the grounding terminal.

6. Set the test time and overcurrent protection value.

7. Before connecting the power supply, return the voltage regulator to zero position, close the knife switch, and the disconnect button light will turn on. If an alarm is required, press the alarm switch, and the alarm will sound and light. Press the start button, the start button light will turn on, and at the same time, the alarm will stop, indicating that the power has been turned on and waiting for voltage rise.

8. Rotate the regulator handle clockwise at a constant speed to increase the pressure, and closely monitor the condition of the control box instrument and the milliampere meter in the sink box.

9. If there is an abnormality in the milliampere meter of the sink box, turn the milliampere meter switch corresponding to the abnormal milliampere meter to the 'on' position to protect the milliampere meter from overcurrent damage.

10. When the required voltage is reached, turn on the time relay switch and the time relay will start timing.

11. When the time relay reaches the set time, the alarm will sound again, reminding that the withstand voltage time has expired.

12. Rotate the regulator handle counterclockwise to reduce voltage, then turn off the time relay switch and press the disconnect button, pull down the knife switch, and the test is over.

13. Unless permitted by the experiment, sudden power outages are not allowed.

14. If the test object short circuits or malfunctions during the experiment, the overcurrent regulator will operate to cut off the high-voltage output.

Product Usage:

1. The voltage withstand test device for insulated boots and gloves is designed to quickly and scientifically complete the power frequency voltage withstand test of commonly used auxiliary insulated tools such as insulated gloves, insulated boots, and insulated rubber pads in accordance with the requirements of the new State Grid Power Generation (2002) No. 777 "Preventive Test Regulations for Electric Safety Tools".

2Direct sales of voltage withstand test device for insulated boots and glovesAuxiliary insulation safety tools refer to insulation strength tools that are not designed to withstand the working voltage of equipment or circuits, but are only used to enhance the security function of basic insulation safety tools, to prevent harm to operators from contact voltage, step voltage, leakage current arc, and cannot directly contact the live parts of high-voltage equipment with auxiliary insulation safety tools. The safety equipment belonging to this part includes insulated gloves, insulated boots, insulated rubber pads, etc.

3. Mainly used for conducting power frequency withstand voltage tests on safety tools such as insulated gloves and boots, in order to determine whether these tools meet the usage conditions and ensure the personal safety of workers.
