Description

technical field [0001] The invention belongs to the technical field of electroscope testing, and in particular relates to a DC electroscope starting voltage test device and a test method. Background technique [0002] The high-voltage electroscope is an electric inspection device for power failure, electric inspection, grounding wire, and electric inspection link in safety technical measures. Its performance integrity is a major safety tool to keep people and equipment safe. State Grid Corporation of China's 2009 "Electricity Safety Work Regulations" stipulates that high-voltage electroscopes should be tested on live equipment before use to confirm that the electroscopes are good. For some places where the conditions are not available (such as single power supply), the safety of personnel and equipment cannot be guaranteed. Due to the lack of corresponding production standards and test standards for DC electroscopes in the country, the market is relatively chaotic. Common ...

For some sites that do not have the conditions (such as a single power supply), the safety of personnel and equipment cannot be guaranteed

Due to the lack of corresponding production standards and test standards for DC electroscopes in the country, the market is relatively chaotic. Common DC electroscopes are divided into three types: positive polarity, negative polarity, and mixed polarity. They need to be provided as corresponding test devices. Positive polarity and negative polarity There are two kinds of high-voltage outputs, and the DC high-voltage generators used in the high-voltage test industry are all negative polarity outputs. Generally, testers need to temporarily build simple test devices, which brings great difficulties to the test profession.
