Open-loop high-voltage induction power acquisition and current monitoring device

Abstract

The invention discloses an open-loop high-voltage power induction draw-out and current-monitoring device, and the device comprises an open-loop power draw-out ring and a controller, wherein the open-loop power draw-out ring comprises a first mutual inductor. The first mutual inductor is in an arc-shaped structure, and the interior of the first mutual inductor is provided with a magnetic steel. The first mutual inductor is wound by an induction coil. The controller comprises a rectification filter circuit, an MTTP control protection circuit, and a stabilized voltage output circuit. The input end of the rectification filter circuit is connected with the output end of the open-loop power draw-out ring, and the output end of the rectification filter circuit is connected with the MTTP control protection circuit. The MTTP control protection circuit is connected with the output end of the open-loop power draw-out ring, and the output end of the MTTP control protection circuit is connected with the stabilized voltage output circuit. The open-loop power draw-out ring is employed as a voltage generation unit, thereby breaking various limits of closed-loop power draw-out, and solving the problems that a conventional mode of power supply is high in cost, is high in operation and maintenance cost, is complex in construction technology, and is poor in stability of power supply.

Description

technical field [0001] The invention relates to a grid line monitoring technology, in particular to an open-loop high-voltage induction power-taking and current monitoring device. Background technique [0002] With the popularization of power line on-line monitoring system, various types of monitoring equipment installed along the line are increasing, and the power supply of these devices has become a problem that must be solved. At present, the following methods are generally used for power supply: [0003] 1. Wired supply: Lay (erect) the cable to the installation point of the electrical equipment through the power supply point. The advantage of this method is that the power supply is reliable, but there is a cable laying project, the cost is high, and it will occupy corridor or channel resources. , the applicability of this method is the price difference when the distance between the supply point and the on-site equipment is far away or there are many points that need to ...
