Abstract

The invention discloses a high-voltage electrostatic discharge apparatus for an antistatic capability test of a power purchase card. The apparatus comprises a high-voltage power supply, the high-voltage power supply is connected with a static discharger, the high-voltage power supply is successively connected with an energy storage capacitor, a high-voltage sampling circuit and a D/A circuit, the D/A circuit is connected with a PLC, and the PLC is connected with a touch screen; the PLC is connected with the high-voltage power supply through an A/D circuit; and the PLC is internally provided with a voltage generation unit, adjusting voltages are generated through a linear function curve, and the adjusting voltages are sent to the high-voltage power supply through the A/D circuit. High-voltage output of the apparatus employs high-voltage grading type compensation, the problem of low high-voltage output precision is solved, the precision is higher than 3%, and it is ensured that test voltages can reach a standard requirement level.

Description

technical field [0001] The invention relates to the technical field of electromagnetic testing, in particular to a high-voltage electrostatic discharge device for testing the antistatic ability of a power purchase card. Background technique [0002] The user card of the smart energy meter is the electricity purchase certificate held by the power user. The power purchase and recharge need to be completed through the information interaction between the user card and the core module of the meter. State write back and other tasks. The user card chip will affect the impedance value between the pins due to the deviation of the electrical characteristics of the pins, or the contact resistance between the pins of the user card chip and the user card chip will change due to factors such as aging, friction, oxidation, and temperature, which may cause the energy meter to The misjudgment of the communication message between the meter and the user card will affect the reliability of the...
