Auxiliary Insulation Tool Testing Device
Darui Electric recommends for you
1. Add two-thirds of water into the water tank and fix it on the insulating platform.
2. Put the insulating boots and insulating gloves with water added into the water tank. The insulating gloves are clamped with the insulating clamp on the probe. The upper openings of the insulating boots and insulating gloves should not be wetted, keeping the upper openings dry.
3. Adjust the tightening screw on the high-voltage tube, insert the probe into the water inside the insulating boots and insulating gloves, and tighten the screw to fix the probe. 4. Ground the water tank box by connecting the grounding post, connect the socket of the water tank box to the output socket of the control box, and turn each milliammeter switch on the water tank 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 turning on the power, return the voltage regulator to zero, close the knife switch, and the disconnect button light will be on. If alarm is needed, press the alarm switch, and the alarm will emit audible and visual alarm. Press the start button, the start button light will be on, and the alarm stops, indicating that the power is on and waiting for voltage increase.
8. Rotate the voltage regulator handle clockwise at a constant speed to increase the voltage, and closely monitor the instruments on the control box and the milliammeters on the water tank box.
9. If any milliammeter on the water tank box is abnormal, turn the corresponding milliammeter switch to the "On" position to protect the milliammeter from overcurrent damage.
10. When the required voltage is reached, turn on the time relay switch, and the time relay starts timing.
11. When the time relay reaches the set time, the alarm sounds again to remind that the withstand voltage time has been reached.
12. Rotate the voltage regulator handle counterclockwise to reduce the voltage, then turn off the time relay switch and press the disconnect button, pull down the knife switch, and the test ends. 13. Unless the test allows, never suddenly cut off the power.
14. During the test, if the test object short-circuits or breaks down, the overcurrent setting device will act to cut off the high-voltage output.
◆Full Chinese interface, working status display, simple and clear operation, wide applicability;
◆With status display and reminder function, users can see the equipment status at a glance;
◆Touch-sensitive panel button operation, all functions can be set via buttons, improving product safety and reliability;
◆Fully digital calibration, abandoning the outdated potentiometer adjustment method, making field use extremely convenient;
◆Buttons directly set target voltage, leakage current, and withstand voltage time, easy to use;
◆With overcurrent and overvoltage protection. Protection is accurate and rapid, effectively ensuring the safety of personnel and equipment;
◆Combining hardware and software anti-interference technology, stable performance, and strong anti-interference capability;
◆Precise voltage control capability with small voltage control error;
◆Time setting range: 1 second to 9999 seconds;
◆Using a high-precision stepper motor to control the voltage regulator boosting process, fully automatic withstand voltage test. After the test starts, the instrument automatically closes the switch and boosts at the speed required by national standards, starts timing when the preset voltage is reached, maintains the test voltage, and after timing is completed, automatically reduces voltage, and after reaching zero, automatically cuts off power, indicating the test is complete, while displaying the leakage current of each test object and the test results;
