[0002] Power transmission and distribution concept includes three aspects, namely power transmission, power transformation, and power distribution; among them, power transmission refers to the transmission of electric energy. Through power transmission, power plants and load centers that are far apart (up to thousands of kilometers) are connected, enabling the development and utilization of electric energy to transcend geographical limitations; the parameter monitoring of transmission lines refers to the monitoring of parameters such as voltage, current, and frequency of transmission lines. By monitoring these parameters, it can be timely found whether the operating state of the transmission line is normal, ensuring the safe and reliable operation of the transmission line.

The bottom of the housing body is fixedly connected with a speaker by screws. Inside the housing body, there are a current transformer, a voltage transformer, a PLC controller, and a storage battery. A terminal block is arranged on the left side wall of the housing body. The wiring terminals of the current transformer and the voltage transformer are connected to the corresponding terminals of the terminal block through wires. The output ends of the current transformer and the voltage transformer are connected to the input interface of the PLC controller through data lines. A driving motor is installed on the right side wall of the housing body through a motor base.

[0004] When installing the existing power transmission and distribution monitoring device, workers usually need to climb the electric pole to fix the device on the electric pole using a hoop. However, the hoop cannot fix the device for a long time. When the hoop is used for a long time, the bolts on the hoop are prone to loosen, resulting in the device slipping off the electric pole. And when tightening the hoop, workers need to use tools to tighten the bolts on the hoop. It is very inconvenient for workers to hold the tools and move on the electric pole. Therefore, there is an urgent need to design a power transmission and distribution monitoring device to solve the above problems. Content of the Utility Model
