Abstract

The application provides a capacitor pulse voltage test device, which includes a mains power supply circuit module, a pulse voltage generating circuit module, a control circuit module, a PLC module and a display module; by using the PLC module for control, automatic switching control is realized to meet different capacities The range of capacitor test parameter requirements solves the technical problem of direct contact between the high-voltage port and the human body and the maximum possible prevention of equipment damage to the experimenter.

Description

technical field [0001] The invention relates to the technical field of component detection, in particular to a safety capacitor pulse voltage test device. Background technique [0002] Safety capacitors are widely used in daily household appliances, and their function is that even if the capacitor fails, it will not cause electric shock and endanger personal safety. When using safety capacitors in power supply cross-line circuits to eliminate noise, not only the normal voltage, but also the generation of abnormal pulse voltages (such as lightning) must be considered, which may cause the capacitor to smoke or catch fire. Therefore, the safety standards for cross-line capacitors are strictly regulated in different countries, so capacitors that have passed safety certification must be used. [0003] figure 1 Published the description of the safety capacitor pulse voltage test in GB / T6346.14-2015, where: Ct—charging or energy storage capacitor; Cp—parallel capacitor; Cx—test...
