High voltage electroscope

Electroscope
1. Overview:
The electroscope is an essential safety tool for power systems and industrial and mining enterprises. It is used to detect whether lines or equipment have operating power frequency voltage to ensure that The personal safety of workers undergoing power outages for maintenance. Hebei Jinneng Electric Power Technology Co., Ltd. produces acousto-optic electroscopes with multiple voltage levels for users to choose and order based on the actual operating voltage level. During the power test, it emits a dual alarm signal of sound and light to remind the staff that the line or equipment under inspection is live.
This electroscope has passed the type test at the Electric Power Industry Electrical Safety Equipment Testing Center, and its main technical indicators comply with

power industry standards and international
technical standards. The product has passed provincial appraisal and been reviewed by the electric power industry, and has been approved for promotion and use across the country.
2.
Usage methods and precautions: (1) Before use, select a qualified electroscope with appropriate voltage level according to the rated voltage of the equipment to be tested. (2) The electroscope must be self-tested before use: the method is to press the self-test button with your finger. If the indicator light flashes intermittently and an intermittent alarm sounds at the same time, it means that the instrument is normal. (3) When performing the above electrical inspection operations, it must be carried out in accordance with the "Safety Working Procedures for the Electrical Industry". Workers should wear insulating gloves and boots, and ensure a safe distance from live equipment. (4) When testing electricity, the staff should hold the handle below the protective ring of the electrical appliance, and according to the provisions of the "Safety Working Procedures for the Electrical Industry", first conduct inspection on the electrical facilities to verify that the performance of the electroscope is intact. It can be used, but the instrument must not be used in rainy and foggy days.
3. Regular experiments: In order to ensure the safety of people and equipment, according to the "Electrical Industry Safety Work Regulations", the electroscope should conduct regular insulation and voltage withstand tests and start-up tests, for three months in a humid place and for three months in a dry place. After half a year, if there is abnormality, use should be stopped. 4. Carrying and storage:
) Avoid falling, squeezing, strong impact, vibration, and do not scrub with corrosive chemical solvents and washing solutions.
) Do not expose it to the sun in the open air. Keep it clean and store it in a dry place.
) This electroscope (indicator) uses a
button and a battery (
Volt)
section. When the self-test
?
switch is pressed, if If the indicator is weak (including abnormal), the battery should be replaced in time.
