Our company is a scientific and technological production and operation enterprise integrating R&D, production and sales. It is a professional enterprise in the production of circuit safety tools. The company has complete testing equipment, advanced means, strong technical force, advanced, novel, reasonable product design and exquisite workmanship. It is a leading product in the domestic manufacturing industry. The series of acousto-optic display high-voltage AC electroscopes developed and produced by our company were tested by the Safety Tool Quality Supervision, Inspection and Testing Center of the Ministry of Electric Power, and all technical indicators are in line with national technical standards.
The series of high-voltage electroscopes adopt sound and light indicators made of electronic integrated circuits, with reliable and stable performance. It has the characteristics of full circuit self-test function, nuclear battery under-voltage display, and strong anti-interference ability. The series of high-voltage electroscopes are suitable for electrical testing of AC power transmission and distribution lines and equipment. Whether it is day or night, indoor substation, station or outdoor overhead line, it can serve you correctly and reliably. It is a necessary safety tool for power systems and electrical departments of industrial and mining enterprises.
2. Main technical parameters:
, usage environment:
(1) Ambient temperature: -℃～+℃
(2) Temperature: ~
(3) Usage occasions: indoor and outdoor weather without rain.
The series of high-voltage AC electroscopes have the following functions
① With full circuit self-test function.
②Battery voltage undervoltage display function.
③Have the ability to withstand certain impact and free fall.
④Has the ability to resist in-phase interference and anti-phase interference.
⑤Ability to distinguish AC induced voltage.
⑥Has the ability to separate DC voltage.
⑦ It has the ability to prevent short circuit and spark intrusion.
3. Usage methods and precautions:
Before use, an electroscope with the same rated voltage should be selected based on the rated voltage of the electrical equipment or circuit to be inspected.
. Take out the electroscope from the bag and wipe it clean with a clean, dry soft cloth. To prevent flashover and fear of electricity.
The electroscope should be self-checked before electrical testing. The method is to press the self-test switch, and the electroscope should send out continuous and intermittent sound and light alarm signals. If there is no audible and visual alarm during self-test, this electroscope part can perform electrical test operation.
. Battery under-voltage indication. When the battery voltage is insufficient, press the self-test switch, and the battery under-voltage indicator light of the electroscope will automatically light up to indicate that the battery should be replaced.
In order to ensure personal safety, the relevant safety regulations of the Ministry of Electric Power should be strictly followed during use. Before use, a power test should be carried out on live equipment with the same voltage level, and it can be used only if it is normal.
The operator must pull all the operating levers out into place before performing electrical inspection operations in the order specified.
The electroscope must conduct preventive tests regularly according to the deadlines specified in the electrical industry work regulations.
If the electroscope is damaged, do not disassemble or disassemble it without authorization.
. The electroscope should be stored in a dedicated place with good air circulation and dry environment.
4. How to replace the battery:
Open the back cover, remove the old battery, and replace it with a new battery according to the battery polarity.
