| With the rapid development of economy and society, people’s production and life demand is increasing rapidly. The requirements for the reliability and stability of power supply are becoming higher and higher. As a routine work in the construction and maintenance of electric power network, the importance of the work of voltage and core is also increasing. Voltage phase check to check needs to be tied or close loop operation of two power system phase sequence, phase, the Que Baosan phase sequence of correct and consistent, non in-phase operation will cause short circuit accident of camera, seriously affect the power grid safe and stable operation.In order to improve the efficiency of the two phase of the nuclear power plant, this paper presents the development of the two voltage and phase device, which improves the efficiency of the core phase, and guarantees the safety of the human body, power network and equipment. In this paper, the method of phase detection is studied and the phase detection scheme is made. The overall scheme of the device, the design scheme of the various departments, and the design of the sub module are studied. By the two voltage phase device of the substation, the two voltage core phase can be operated by 1 persons. The average time of the operation of the substation operation is not more than 3 minutes.Around the implementation of the device technology, this paper analyzes the advantages and disadvantages of various schemes, and the optimal scheme is determined by the decomposition of the selected scheme. In order to achieve the best plan, the implementation strategy was formulated, and according to the strategy table, each component was carried out. The test and field application of the two voltage device was carried out. Finally, the use of the device is standardized, and the device in Dezhou power supply company to promote the application. The two voltage nuclear device is completely in line with the requirements of the substation site voltage and core, stable operation, safe and reliable, simple operation, high efficiency, and has a high application value. |
