Abstract

The invention specifically provides a synchronous detection system for an intelligent transformer substation device. The problem that an existing transformer substation device is large in labor intensity, low in effect and free of detection result reliability is solved. The synchronous detection system for the intelligent transformer substation device comprises a satellite signal receiving device, a satellite signal demodulation unit, a clock synchronization adjustment device, an operation parameter acquisition device, a wireless communication unit, a detected device and a control room mainframe. The transmitting end of the satellite signal receiving device is connected with the receiving end of the satellite signal demodulation unit, the transmitting end of the satellite signal demodulation unit is connected with the receiving end of the clock synchronization adjustment device, the clock synchronization adjustment device is connected with the detected device, the output end of the detected device is connected with the input end of the operation parameter acquisition device, the output end of the operation parameter acquisition device is connected with the input end of the wireless communication unit, and the output end of the wireless communication unit is connected with the input end of the control room mainframe. The synchronous detection system for the intelligent transformer substation device ensures that a detection result is accurate and reliable.

Description

technical field [0001] The invention relates to a substation detection system, in particular to an intelligent substation equipment synchronous detection system. Background technique [0002] A substation is an assembly of some equipment to cut or connect, change or adjust voltage. In the power system, the substation is the assembly point of power transmission and distribution. It is a power facility that transforms voltage, receives and distributes power, controls the flow of power and adjusts voltage. It connects the power grids of all levels of voltage through its transformers. The power transformation and transmission of the entire substation is accomplished through the cooperation of various devices. Any failure of any device will cause the substation to fail to work normally. Therefore, regular testing of substation equipment is essential. The normal operation of each device can successfully complete the power transmission and provide users with better and more stable...
