The working principle of the utility model wireless high-voltage electroscope:

The principle is: electro-optic effect. By detecting the magnitude of the electric field strength of the charged body, the magnitude of the voltage is calculated to determine whether the wires and equipment are charged. ' Wireless high voltage electroscope ' is a new generation of electroscope developed by electro-optic effect. It breaks through the shackles of traditional electroscope design theory and thinking, and it is safer, more convenient and reliable to use.

The electric inspection operation steps of the utility model wireless high-voltage electroscope:

Turn on the power for self-test;

Before using the wireless high-voltage electroscope of the utility model , the electroscope must be carefully inspected. If cracks are found in the electroscope, the installation of each component is not fastened, etc., it must not be used. After starting up, only the electroscope that has passed the self-inspection can be used for the electric inspection operation. Whether the self-test of the electroscope is passed can be judged according to the following phenomena:

1. Turn on the power switch, and the LCD will display the self-test interface. If it does not enter the working interface, it means that the electroscope has failed and should stop working.

, Whether the battery power is sufficient or not, there is an icon on the LCD, if the battery power is seriously low, a red alarm will appear on the LCD, and you should stop using it immediately.

, High-voltage AC live equipment for electric inspection operation steps:

A. Switch to the corresponding voltage level detection gear.

B. The operator is located directly below the phase conductor under test, lifts up the electroscope, presses the visible laser switch button, the electroscope as a whole is higher than the top of the head, and aims the laser at the conductor or equipment under test (do not let the head, cap or other objects blocking the electroscope).

C. Press and hold the detection switch, when the buzzer emits a beep, it indicates that it has entered the detection state. After 5 seconds, when the buzzer emits a beep again, it indicates that the detection is completed (during the detection process, if there is no Ensure the correct test posture or release the working button in advance, and the buzzer will emit two beeps, indicating that the monitoring is invalid, and the original phase detection should be restarted until the correct test is completed).

D. According to the same method as above, detect the other two phases sequentially ( note: three phases must be detected sequentially ).

E. When all the three phases are tested correctly, the electroscope will judge whether the tested equipment is live or not. If the buzzer beeps, beeps, and beeps continuously, and the LCD shows that ABC is powered, it means that the wire or equipment under test is charged; if there is no alarm sound, and the LCD shows that ABC has no power, it means that the wire under test is not charged.
