Embodiment Construction
[0018] The specific implementation steps of the method for debugging electrical equipment, valve equipment and instrumentation equipment in the installation process of the nuclear power plant of the present invention are as follows: first, set up a circuit, that is, the output end of the AC power supply is connected with the input end of the voltage regulating element, and the output end of the voltage regulating element is connected with the input end of the voltage regulating element. The input end of the bridge rectification circuit is connected, the output end of the bridge rectification circuit is connected with the input end of the filter circuit, and the output end of the filter circuit is connected with the input end of the device to be debugged. The AC power supply can be daily electricity, that is, the 220V (volt) 50Hz (Hertz) AC power used in the nuclear power plant construction site, or the AC power with a rated output voltage of 380V or other values. Then, the circ...

The invention relates to installation of a nuclear power station, aiming at solving the problems that the existing method for debugging electrical and instrumental equipment has high debugging cost and is inconvenient. The invention provides a method for debugging electrical equipment, valves and instrumental equipment in the installation process of a nuclear power station, comprising the following steps of: firstly, connecting the output end of an AC (alternating current) power supply with the input end of a voltage regulating element, connecting the output end of the voltage regulating element with the input end of a bridge rectifier circuit, connecting the output end of the bridge rectifier circuit with the input end of a filter circuit, and connecting the output end of the filter circuit with the input end of equipment to be debugged; then connecting the circuit and adjusting the voltage regulating element; starting the equipment to be debugged, enabling the equipment to be in an operating state continuously for a period of time, checking whether the equipment can normally operate, if so, turning off the equipment to be debugged and cutting off the power supply; if not, turning off the equipment to be debugged, adjusting the related components, restarting the equipment to be debugged, repeating the operation until the equipment can normally operate; and if the equipment can not normally operate after repeating the operation multiple times, rejecting the equipment. The debugging method has low cost and is convenient.
Description
technical field [0001] The invention relates to the installation of a nuclear power plant, in particular to a method for debugging electrical equipment, valve equipment and instrumentation equipment during the installation process of the nuclear power plant. Background technique [0002] Since the electrical equipment in nuclear power plants is upgraded with the continuous upgrading of technology, in order to improve safety, during the construction of nuclear power plants, electrical equipment, testing instruments, valve equipment, and single units such as contactors, relays, and voltage transmitters must be Body electrical components for electrical debugging. After the above-mentioned commissioning is completed, a simulation test must be carried out on the installed electrical system with a DC power supply before it can be put into operation. [0003] At present, those skilled in the art usually directly connect the output terminal of a DC power source purchased from the m...
