[0003] An electroscope is an instrument for detecting whether an object is electrified and roughly estimating the amount of electrification. It is divided into a low-voltage electroscope and a high-voltage electroscope. It is used to test high-voltage electrical equipment with a voltage of more than 250V to the ground. In the prior art, high-voltage electroscopes can only perform live detection on equipment with nominal voltage levels. Different voltage levels require different electroscopes, and for AC and DC , also requires different electroscopes, and when using an electroscope, it must be noted that its rated voltage is compatible with the voltage level of the electrical equipment being tested, otherwise it may endanger the safety of the electroscope and the operator or cause misjudgment

Description
technical field [0001] The invention relates to the field of electric power, in particular to an AC / DC high-voltage electroscope. Background technique [0002] In recent years, with the development of my country's economy, the modernization of the power industry, which is the lifeblood of the national economy, has shown increasing importance. People's demand for and dependence on electricity is increasing day by day, and ensuring the safe and reliable operation of the power supply system has become the primary task of the power management department. [0003] An electroscope is an instrument for detecting whether an object is electrified and roughly estimating the amount of electrification. It is divided into a low-voltage electroscope and a high-voltage electroscope. It is used to test high-voltage electrical equipment with a voltage of more than 250V to the ground. In the prior art, high-voltage electroscopes can only perform live detection on equipment with nominal voltag...
