Embodiment Construction

[0009] The invention provides an intelligent fault monitoring method for power transmission and transformation, which is characterized in that it first collects the current signal on the transmission line through an induction coil to form a sampling signal, and then converts the sampling signal through a rectifier circuit to analog to digital Convert the digital signal into a digital signal and send the digital signal through the wireless signal, then input it into the database of the monitoring host for signal storage, then compare and judge with the information stored in the database, and then judge the location and type of the fault through the data analysis device, monitor The output end of the main engine is connected with an alarm device and a fault display device. The fault display device displays the type and location of the fault and sends it to the maintenance personnel through SMS or WeChat for troubleshooting. Once a fault occurs, it can guide the maintenance personn...

Abstract

The invention discloses a power transmission and transformation intelligent fault monitoring method. The method includes: collecting current signals on a power transmission line through an induction coil, and forming a sampling signal; subjecting the sampling signal to analog-digital conversion through a rectifier circuit to form a digital signal, sending the digital signal out through a wireless signal, and input the digital signal into a database of a monitoring host for signal storage; comparing the digital signal with information stored in the database for judgment; judging fault position and fault type through a data analysis device, wherein an output end of the monitoring host is connected with an alarming device and a fault display device, the fault display device displays the fault type and position or sends the same to maintenance personnel for fault handling through short messages or Wechat messages, and the maintenance personnel can be guided to quickly find a fault point once a fault appears. The method is conducive to quickly and timely finding lines with faults, ensuring safe running of the whole power transmission line and reducing economic loss caused by the faults of the power transmission line.

Description

technical field [0001] The invention relates to an intelligent fault monitoring method for electric power transmission and transformation. Background technique [0002] With the increasing scale of the power system, the number of transmission lines is increasing, and the transmission lines are oxidized and corroded during the long-term operation. , how to detect the fault of the transmission line, so it is very necessary to detect the transmission line. Traditional detection generally uses manual search, which increases the time and difficulty of search, and the work efficiency is not high. Contents of the invention [0003] The invention provides an intelligent fault monitoring method for electric power transmission and transformation, which not only helps to quickly and timely find faulty lines, but also ensures the safe operation of the entire transmission line and reduces economic losses caused by transmission line failures. [0004] The present invention adopts the ...
