墙绘The high-voltage electroscope adopts integrated circuit design, has high sensitivity to electrical inspection, is not affected by sunlight and noise, can be used day, night, indoor and outdoor, has strong anti-interference, is equipped with overvoltage protection and temperature automatic compensation circuit, has a full circuit self-test function, is equipped with electronic automatic switching, and has taken good shielding measures to ensure reliable operation under high voltage and strong electric fields.The high-voltage electroscope is currently an ideal product for the upgrading of the domestic power industry, and it is also an essential appliance for power plants, substations, industrial and mining electrical departments. The following matters must be paid attention to when using it.：
1. Before use, electroscope and telescopic insulating rod of suitable voltage level should be selected according to the rated voltage of the electrical equipment under inspection.
2. For power inspection operations in non-all power outages, the high-voltage electroscope should be tested on the electrical site first, then on the construction site for testing, and then returned to the electrical site for retest to ensure that**, The self-test button test of the electroscope shall not be used to replace this operation. The self-test button test is for reference only.
3. When performing power verification operations in all power failure situations, the “high voltage signal generator” of the corresponding voltage level should be used before the power verification operation to verify the integrity of the electroscope before the power verification operation can be carried out.
4. When using, all the telescopic insulating rods should be pulled apart. The operating hand cannot cross the prescribed ring. The electroscope contacts are in contact with the same level of charged body. If the electroscope emits intermittent sound and light signals, it indicates that the charged body has electricity. If the electroscope does not emit sound and light signals, it indicates that the charged body is not charged.
5. When using a high-voltage electroscope to perform electrical inspection operations on electrical equipment, it should be carried out in accordance with the electrical industry** work regulations. In order to ensure the safety of persons and equipment, the electroscope must conduct regular preventive tests in accordance with the time limit specified in the electrical industry**work regulations.
6. If it is not used for a long time, the battery should be removed to avoid the battery liquid from overflowing and corroding the parts. If you need to replace the battery, just unscrew the upper cover of the electroscope, remove the battery baffle, and replace it with a new battery.
7. The high-voltage electroscope should be stored in a place with air circulation and a dry environment, and special attention should be paid to moisture-proof so as not to affect the use and life of the electroscope.
8. The normal service life of the electroscope is three years from the date of leaving the factory. If it exceeds the service year, it should be inspected before it can be used. The long service life shall not exceed five years.
