The invention discloses a monitoring device of transmission tower deformation based on a parallel plate capacitor. The device comprises an angle iron frame fixedly installed on a top of a transmissiontower. The angle iron frame is provided with a power supply component. A lower portion of the angle iron frame is equipped with an upper pole plate through a bolt in a suspending mode. The upper poleplate and the transmission tower form a plate capacitor. The angle iron frame is provided with a signal processing device. The signal processing device is connected to the power supply component in alead connection mode. The invention also discloses a monitoring method. The method comprises the following steps that the monitoring device of transmission tower deformation based on the parallel plate capacitor is constructed; a charge measurement module measures a charge value of the parallel plate capacitor and sends the value to a microprocessor; and the microprocessor processes the charge value and then acquires a deformation quantity, and sends the deformation quantity to a monitoring center so as to realize online deformation monitoring of the transmission tower. By using the device and the method, when a key tower material of the tower is deformed to a certain degree, maintenance or replacement measures are taken timely to solve defects of traditional manual line inspection and reduce accidents caused by the deformation of the tower material.
Description
technical field [0001] The invention belongs to the technical field of power transmission line state monitoring equipment, and in particular relates to a monitoring device for deformation of a power transmission tower based on a parallel plate capacitor, and also relates to a method for monitoring deformation of a power transmission tower based on a parallel plate capacitor. Background technique [0002] In power installations, transmission towers are an important part of transmission lines. It will inevitably pass through unattended areas such as mountains, hills, and loose soil. In recent years, accidents of deformation of transmission towers due to tower foundation settlement and mountain collapse have occurred frequently. In severe cases, the tower will be broken and the line will be broken, resulting in large-scale power outages and immeasurable economic losses. [0003] For the monitoring of transmission towers, it mainly relies on manual line inspection. However, m...
