The transmission line monitoring terminal usually adopts the form of upper and lower components of a whole that can function independently, and when the on-site installation is carried out, the upper and lower parts are locked on the transmission line by using screws or bolts. On an alternating current power transmission line, a terminal obtains electric energy on the power transmission line through energy taking CT induction, and the running and surrounding environment states of the power transmission line are monitored. In order to install on the power transmission line, the magnetic conductor of the energy-taking coil is divided into an upper part and a lower part; because of the existence of the matching gap of the magnetizer, the energy-taking coil can generate alternating electromagnetic force when in work, and the action of the electromagnetic force causes the continuous vibration of the terminal in a power-on state. The fixed connection of the upper part and the lower part of the energy-taking coil can be damaged by continuous vibration for a long time; the locking structure of the terminal on the transmission line is also damaged. The energy-taking coil is fixedly connected and damaged, a power supply system of the device fails, and the device stops running; the locking structure is damaged, and the terminal has the potential safety hazard of coming off from the power transmission line.
