Abstract

The invention discloses a system and a method for overcurrent protection and voltage monitoring device burn-in test. The system comprises a cabinet, a front-end processor, a test signal source, an acquisition control device, and a switching power supply. The method comprises: the front-end processor parsing a test case to a control command; the test signal source sending test signals to the acquisition control device; the acquisition control device receiving the control command, and acquiring monitored data of the overcurrent protection and voltage monitoring device, and feeding back to the front-end processor. The overcurrent protection and voltage monitoring device comprises a relay panel, a mainboard, and a display screen. The relay receives test signals. The display screen sets a given threshold value. The mainboard receives a burn-in test. The system and the method for overcurrent protection and voltage monitoring device burn-in test use automated, intelligent, and integrated online monitoring measures, and can accurately and efficiently test functions of the overcurrent protection and voltage monitoring device, and can find out defects of the overcurrent protection and voltage monitoring device, so as to effectively reduce fault risks of nuclear power station circuits.

Description

technical field [0001] The invention relates to the on-line monitoring technology of power equipment in nuclear power plants, in particular to a copying test system and method for overcurrent protection and voltage monitoring devices in nuclear power plants. Background technique [0002] The over-current protection and voltage monitoring device is one of the important components of nuclear power plant circuit protection. It is mainly used for over-current protection of the circuit in the power grid system of the nuclear power plant, and can display the voltage value of the bus in the system. Once the safe setting current value and action time are set, when the current in the circuit exceeds the setting range, the overcurrent protection and voltage monitoring device will control the internal relay to operate, thereby disconnecting the circuit and preventing accidents. However, during long-term operation, the circuits on the overcurrent protection and voltage monitoring device...
