How to use and precautions for high-voltage sound and light electroscope

Usage methods and precautions When using an electroscope, you must pay attention to the fact that its rated voltage is consistent with the voltage level of the electrical equipment being inspected. Otherwise, the personal safety of the electroscope operator may be endangered or misjudgment may occur. During the electrical test, the operator should wear insulating gloves and hold the handshake part below the protective ring of the cover. First, conduct the test on the live equipment. During the test, the operator should gradually move the electroscope closer to the live equipment until it glows or makes a sound to confirm. The performance of the electroscope is intact. If the electroscope has a self-test system, you should first press the self-test button to confirm that the electroscope is intact, and then test it on the equipment that needs to be tested. During the test, you should also gradually move the electroscope closer to the equipment to be tested. Until it touches the conductive part of the equipment, if there is no sound or light indication during this process, it can be determined that the equipment is not charged. On the contrary, if it suddenly lights up or makes a sound during the process of moving closer, it is considered that the equipment is charged, and you can stop moving closer and end the test. electricity. In addition, the windshield type electroscope is only suitable for use indoors or outdoors in good weather. It is prohibited to use it under rain, snow and other environmental conditions.
High-voltage sound and light electroscope
High-voltage sound and light electroscope is a special tool for detecting whether electrical equipment is live in power companies, such as power plants and substations. It has sound and light warnings for on-site operation, which is safe, reliable and has a long life. Telescopic tie rod insulators are easy to use.
Functions and features
. Detect whether there is power frequency voltage on high-voltage AC lines and equipment. .Sound and light alarm, dual display to ensure work safety.
Use and Maintenance
.Self-test must be performed before use by pressing the self-test button with your finger. The indicator light should flash intermittently, and it should emit an intermittent alarm sound. Indicates that the instrument is normal. .When performing the above electrical inspection operations, workers must follow the "Electrical Industry Safety Work Procedures" and wear insulating gloves and shoes, and ensure a safe distance from live equipment. .When using it, workers should hold the bottom part of the insulating rod to ensure the effective length of the insulating rod. According to the provisions of the "Safety Working Procedures for the Electrical Industry", they must first conduct inspections on electrical facilities to verify the actual performance of the electroscope. In good condition before use. .The electroscope should perform insulation withstand voltage tests and start-up tests regularly. Three months in humid places and half a year in dry places. If you find that the product is unreliable, you should stop using it. .Do not use in rainy or foggy days. .The electroscope should be stored in a dry, ventilated place free of corrosive gases.
