Intrinsically safe power supply performance dynamic test system

Abstract

The invention provides an intrinsically safe power source performance dynamic test system. The system comprises a power source module of which the input end is connected to a mains supply and which is used for converting mains power into direct-current power and outputting the direct-current power, a voltage loading module of which the input end is connected to the output end of the power source module and which is used for converting the direct-current voltage output by the power source module into a voltage needed for test of a tested intrinsically safe power source and loading the voltage to the tested intrinsically safe power source, a current loading module of which the input end is connected to the output end of the power source module and which is used for converting the power output by the power source module into a current needed for test of the tested intrinsically safe power source and loading the current to the tested intrinsically safe power source, and a control module which is used for outputting a control signal to the voltage loading module or the current loading module according to the output voltage or output current of the tested intrinsically safe power source so as to change the loading voltage output by the voltage loading module or the loading current output by the current loading module. With the system, the performance status of an intrinsically safe power source can be analyzed accurately, an intrinsically safe power source with safety risks can be eliminated effectively and prevented from continuing working in a coal mine, and the safety in production is ensured effectively.

Description

technical field [0001] The invention relates to a test system, in particular to a dynamic test system for intrinsically safe power supply performance. Background technique [0002] Intrinsically safe output power is referred to as intrinsically safe power supply, which is widely used in underground operations in coal mines and other mines. Due to the special working environment of coal mines (with explosive gas and other dangerous factors), the performance requirements for intrinsically safe power supplies are extremely high. Therefore, for The performance test of the intrinsically safe power supply and the operation status of the intrinsically safe power supply through the test are the most important to ensure the safe production of the mine. The existing test methods and test equipment are not accurate, and the measured parameters are difficult to accurately analyze the intrinsically safe power supply. Performance status, so that there is a serious potential safety hazard ...
