Abstract
The invention provides a power taking measurement circuit, method and equipment for a power transmission line. The circuit comprises an induction power taking coil, a measurement circuit, a control module, a first energy storage module, a switch module, a transformer module and a lockout circuit, the induction electricity-taking coil is connected with the primary side of the measuring circuit. The secondary side of the measuring circuit is connected with the control module. If the control module receives a target measurement instruction and the voltage of the first energy storage module is smaller than a preset voltage threshold value, the control module locks the output of the switch module through the lockout circuit, the first energy storage module stores energy, and the transformer module stops electromagnetic energy transmission until the voltage of the first energy storage module reaches the preset voltage threshold value; performing measurement according to the target measurement instruction; and after the target test instruction is completed, if the voltage of the first energy storage module reaches a preset voltage threshold value, the output of the switch module is opened through the lockout circuit, and the transformer module performs electromagnetic energy transmission. Therefore, measurement accuracy can be improved, and equipment weight and size can be reduced.
