Inverter static bypass switch voltage monitoring card work performance test system and inverter static bypass switch voltage monitoring card work performance test method

Abstract

The invention relates to an inverter static bypass switch voltage monitoring card work performance test system and an inverter static bypass switch voltage monitoring card work performance test method. The test system, which is used for testing the work performance of an inverter static bypass switch voltage monitoring card, comprises a front-end control device, a signal generation device, an acquisition control device and an acquisition adapter device. The front-end control device is used for receiving different test cases and parsing the test cases into different control commands. The signal generation device is used for receiving a signal excitation command and sending a test signal to the acquisition control device. The acquisition control device is used for receiving a test control command and the test signal and sending the test signal to the acquisition adapter device according to the test control command. The acquisition adapter device is used for receiving the test signal, conditioning the test signal and outputting the test signal to the monitoring card to test the work performance. With the test system and the test method, the defects in the prior art, for example, a lot of artificial operation is needed, the requirement on operators is high, and the function cannot be tested comprehensively, are solved.

Description

technical field [0001] The invention relates to the on-line monitoring technology of power equipment in nuclear power plants, and more specifically relates to a working performance testing system and method for a static bypass switch voltage monitoring card of an inverter. Background technique [0002] Now Daya Bay, Ling Ao Phase I, and Ling Ao Phase II nuclear power plants generally use uninterruptible power supplies to ensure the safe and stable operation of the power plants. The inverter card is a very important part of the uninterruptible power supply. An important card for the normal operation of the system. Different types of inverter cards can be used for different power supply systems. [0003] Inverter systems such as LNH, LNP, and LNG are commonly used equipment in Daya Bay and Ling'ao nuclear power plants. figure 1 is a schematic diagram of a common inverter system. The inverter system is mainly composed of an inverter and a protection control circuit. The bypas...

Problems solved by technology

However, after long-term operation or misoperation, it may cause the aging of the card parts and various hidden troubles. If it is not handled in advance, it will affect the normal operation of the power supply unit and cause unnecessary losses.

[0004] At present, there is a lack of targeted research on the internal components of nuclear power plant inverters in China. The maintenance or replacement of this type of components depends on the manual inspection of the relevant cabinets of the overall inverter system or simple appearance identification. To determine the working status of the card, it is impossible to conduct power-on test and analysis on the old card automatically or in batches, and there is a lack of means for intelligent inspection and diagnosis of hidden card failures
