Embodiment Construction

[0013] Hereinafter, preferred embodiments of the present invention will be described in detail by referring to the accompanying drawings.

[0014] Withstand voltage test refers to the test of the withstand voltage capability of various electrical devices, insulating materials and insulating structures. The process of applying a high voltage to an insulating material or insulating structure without destroying the performance of the insulating material is called a withstand voltage test. Generally speaking, the main purpose of the withstand voltage test is to check the ability of the insulation to withstand working voltage or overvoltage, and then to check whether the insulation performance of the product equipment meets the safety standards.

[0015] Such as figure 1 as shown, figure 1 Shown is a schematic diagram of the withstand voltage test. The basic principle of the withstand voltage test is as follows: a voltage higher than the normal working voltage is applied to the ...

Abstract

The invention discloses a voltage resistance test system, comprising a program control power supply model for providing a needed test voltage; a signal collection modulation module for testing the low voltage provided by the program control power supply model, measuring the leak current passing an object when the low voltage meets a preset voltage value, outputting a voltage signal corresponding to the leak current, and cutting off the circuit when the leak current is higher than a preset value; and a control module for controlling the output of the program control power supply module, receiving the low voltage received and processed by the signal collection modulation module, comparing the processed low voltage with a preset value, and receiving the voltage signal output by the signal collection modulation module and corresponding to the leak current when the processed low voltage meets the preset value. The voltage resistance test system has stable performance, improved test accuracy, automatic test parameter configuration, friendly software interface and simple operation.

Description

technical field [0001] The invention relates to a withstand voltage testing technology, in particular to a withstand voltage test system for electrical safety performance testing. Background technique [0002] Electrical safety performance parameters are one of the indicators of national compulsory certification, and they are also important parameters reflecting the safety performance of electronic products and equipment. In 2001, the IEC1010 standard - "Safety of Electrical Equipment for Measurement, Control and Laboratory Use" was revised to IEC61010. [0003] The main test indicators of electrical safety include AC / DC withstand voltage, insulation resistance, leakage current, grounding resistance, etc. The AC / DC withstand voltage test is used to test the electrical safety performance of the product under actual working conditions, and is one of the important indicators for testing the electrical safety performance of the equipment. At present, most of the pressure teste...
