"It's the Mid -Autumn Festival. We must strengthen the inspection of important routes, and do a good job of maintaining the high -precision temporary recording of the wave -type fault indicator of the network line, so that everyone reunion over the festival." In the early morning of September 7, Zhengzhou Zhou Yonggang, the squad leader of the second class of the power supply company of the power supply company, arranged the task of deploying the day to ensure the safe and reliable power consumption of residents in the jurisdiction.

Zhou Yonggang's high -precision temporary recording wave -type fault indicator is a device that can monitor the operating status of the line line and accurately determine the fault location in real time. In the traditional power supply network, due to the large number of distribution network branches and complicated structures, when the failure occurs, it takes a lot of manpower, material resources and time to complete the repair work. At present, this device can convert the recorded faulty waveform data into a fault interval and send it to the mobile phone of the operational inspection personnel, thereby achieving a fast and accurate positioning of the fault point, which greatly reduces the duration of the failure.

It is understood that there are 54 10 kV lines with a single length of more than 5 kilometers in the area under the jurisdiction of Chengxi Power Supply Company. Some lines have a long power supply radius and the regional mesh is weak. In order to improve the reliability of power supply, since March, Zhengzhou Power Supply Company combined with the line characteristics and user characteristics in the region, to install a long -term air -to -electricity station such as 110 kV Gaulin, install high -precision temporary recording wave type fault indicator 106 sets, the grounding failure of 98 over -override lines is accurate. Since the installation of the fault index, the fault search time was shortened by more than 45%year -on -year, and the number of households decreased by 34.4%year -on -year during the cumulative power outage.

On the evening of July 25, Zhengzhou encountered a rare thunderstorm weather. After receiving the SMS reminder of the power outage range of the "Tuqiang to change to the 13#rod of the Zhaopo Line of Figure 33" After recovering power supply, the whole process was only half an hour. "10 kV maps 33 board lines have a power supply radius of more than 7 kilometers. If this is in the past, the re -power time can be longer." Zhou Yonggang said with a smile.

In the next step, Zhengzhou Power Supply Company will expand the application scope and functions of the device on the basis of popularizing the application of high -precision temporary recording wave -type fault indicator, creating an intelligent distribution network line status monitoring system, and further enhance the technical capabilities of the team, operation and maintenance, operation and maintenance The level, welcomes the 20th National Congress of the Party with practical actions and outstanding achievements.
