Pressure-resistant test system

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...

Problems solved by technology

At present, most of the withstand voltage testers used adopt the GB4706 (equivalent to IEC1010) standard, and most of them are single-item test index test instruments with a desktop structure, which cannot meet the needs of users for multi-index comprehensive testing.

Moreover, the current withstand voltage tester mostly adopts the traditional test method, and the test accuracy is not high, which directly affects the quality of electrical products, so it cannot fully meet the needs of the current development of electrical safety performance testing.
