Shande Electric sells a series of high-voltage electroscopes. The high-voltage electroscopes are made of electronic integrated circuits with audible and visual indications, and have stable and reliable performance. It has the characteristics of full circuit self-checking function and strong anti-interference. 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 substations or outdoor overhead lines, they can serve you correctly and reliably. , is a necessary safety tool for power systems and electrical departments of industrial and mining enterprises.
Before the electrical test, all the insulating rods of the electroscope must be pulled out.
When testing electricity, you must hold the handle of the insulating rod so that the indicator electrode is in good contact with the charged object. If there is a sound and light alarm, it indicates that it is charged. If there is no sound or light, it is verified that it is not charged.
When using an electroscope to test electricity, you must wear auxiliary insulation tools such as insulating gloves and insulating boots.
Electron transfer, the electrons on the charged conductor will be transferred to the electroscope. The live conductor is removed and the electroscope foil continues to open.
By detecting the current flowing through the electroscope to ground stray capacitance, check whether the equipment and lines are live.
The connection of each part of the electroscope is firm and reliable, the indicator is well sealed, the surface is smooth and flat, and the mark on the indicator is complete. The surface of the insulating rod is clean and smooth.
High-voltage electroscopes are mainly used to test high-voltage electrical equipment whose ground voltage is above. Three types are widely used: luminous type, acousto-optic high-voltage electroscope type, and windmill type. High-voltage electroscopes generally consist of three parts: the detection part (indicator part or windmill), the insulation part, and the handshake part. The insulating part refers to the part from the metal connecting screw at the bottom of the indicator to the cover guard ring, and the handshake part refers to the part below the cover guard ring. The insulation part and handshake part have different lengths according to different voltage levels.
Press the test button on the high-voltage electroscope, the piezoelectric ceramic piece and the slide wire indicator light-emitting diode alarm are normal, indicating that the internal circuit and drive circuit of B, the piezoelectric ceramic piece and the light-emitting diode are normal, and the fault is in the front-end induction detection source. Trigger the control circuit and use a multimeter to check R and R. It is found that the resistance of R has increased to It is used to detect whether lines or equipment have operating power frequency voltage to ensure the personal safety of workers during power outages for maintenance. Our company produces a series of sound and light electroscopes, which are divided into seven voltage levels from . 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 Electric Safety Equipment Testing Center, and its main technical indicators comply with the 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 nationwide
