The invention discloses a system and method for testing the function of a protecting card. The system comprises a front-end processor, a testing signal source, an acquisition control device, an adapting device, a switching power supply, a temperature and humidity monitoring device, a heater, and a fan. The front-end processor receives an environmental parameter of the temperature and humidity monitoring device and transmits a first adjusting signal and a second adjusting signal to the heater and the fan. The testing signal source receives a control instruction. The acquisition control device receives a control instruction. The temperature and humidity monitoring device detects an environmental parameter in the system for testing the function of the protecting card. The heater adjusts the temperature in the system for testing the function of the protecting card. The fan adjusts the temperature in the system for testing the function of the protecting card. The system and method for testing the function of the protecting card use an automated, intellectualized, and integrated online monitoring means and may accurately and high-efficiently test the function of the protecting card, and the temperature and humidity monitoring device, the heater, and the fan may adjust and control the environmental parameter in cooperation so as to provide an appropriate work environment for the devices.
Description
technical field [0001] The invention relates to the on-line monitoring technology of power equipment in nuclear power plants, in particular to a function testing system and method for protection cards of nuclear power plants.
