High-pressure electroscope REpower,] the composition of high-pressure electroscope: by electroscope shell using ABS engineering native plastic injection molded telescopic insulated operating rod manufactured by epoxy insulating rod, rod became head one storage more convenient to use. 4 the AG13, No. Oxygen silver battery, voltage 6V. High-voltage sound and light electroscope Overview: The electroscope is a power system and industrial and mining enterprises electricity operations essential security tools, it is used to detect the voltage of 0.1kV-500kV lines or equipment with operating frequency to ensure that a power outage overhaul The staff's personal safety. Shijiazhuang REpower Power Tools Co., Ltd. production GDY-II-type sound and light electroscope 0.1kV to 500kV of seven voltage level products, select the order for the user to press the actual operating voltage level. Examine the electrical sound and light dual alarm signal is issued to alert staff lines or equipment was seized charged. The electroscope type test in the electric power industry electrical safety tools and instruments Testing Center, the main technical indicators comply with DL740-2000 power industry standards and international IEC standard. Products passed the provincial appraisal and review of the electric power industry, agreed to use across the country. The introduction of the low-pressure electroscope: it is used to test voltage 250V and below the low-voltage electrical equipment, is also commonly used in the household electrical safety tools. It is mainly by work contacts, dropping resistor, neon bulb, springs and other components. This electroscope using current loop formed by the electroscope, human, earth, the leakage current of the neon bulb starter luminous work. As long as the charged body between the earth and the potential difference exceeds a certain value (36V), the electroscope glow below the value, not luminous, so as to determine whether the low-voltage electrical equipment with voltage. High-pressure electroscope works: (1) electron transfer, the electronic live conductors will be transferred to the electroscope. Removal of the live conductor, electroscope metal foil open. (2) by detecting the flow through the electroscope stray capacitance current inspection equipment, whether the line is charged. Coupling of the various parts of the electroscope is solid, reliable indicator sealed, smooth surface the indicator flag integrity. Insulated rod surface clean and smooth.
