Abstract

The invention belongs to the technical field of nuclear power station maintenance, and particularly relates to a nuclear power station maintenance power supply intelligent control device which comprises a 380V alternating current power supply, a circuit breaker QF, a current transmitter TA, a contactor KM, an XS1 socket, a 24V power supply, a PLC2 module, a fingerprint module, a PLC1 module and anintermediate relay KA. The method comprises the steps that maintenance power supply equipment is connected with the XS1 socket, the fingerprint module acts to send out a fingerprint action signal, and the fingerprint action signal is sequentially transmitted to the PLC1 module and the PLC2 module; the PLC2 module sends out a signal and transmits the signal to background monitoring equipment; themonitoring equipment receives the signal sent by the PLC2 module and sends an instruction to the PLC2 module, and the PLC2 module controls a coil of the intermediate relay KA to be powered on, so thatthe XS1 socket is powered on; and the PLC2 module sends the power-on signal information of the XS1 socket to the background monitor or a mobile phone. State monitoring and data acquisition of nuclearpower station maintenance equipment can be realized, and operation of different levels of electricity utilization personnel is limited through functions of biometric identification fingerprint inputand the like.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant maintenance, and in particular relates to an intelligent control device and control method for a nuclear power plant maintenance power supply. Background technique [0002] In the process of equipment installation and commissioning in nuclear power plants, maintenance of power supply equipment is frequently used. There are many problems in the use of existing maintenance power supply equipment, such as the inability to realize remote control, lack of electrical protection, and incapability of real-time monitoring. The current management methods for overhauling power supply equipment and the extensive use methods on site cannot meet the needs of safety management. [0003] Therefore, in the process of using the power supply equipment for maintenance, it is particularly important to be able to realize remote control and real-time monitoring of the status of the power supply equipment fo...
