Abstract

The invention relates to an inductive power-taken high-voltage power verifying displayer and aims to solve the problem that the conventional high-voltage power verifying display device is deficient. The inductive power-taken high-voltage power verifying displayer comprises a passive induction power-taken part, wherein the passive induction power-taken part is connected to a reception controlling module; the reception controlling module is connected to a trigger displayer; the passive induction power-taken part, the reception controlling module and the trigger displayer are connected to an inductive power-taken device; the inductive power-taken device is connected with a storage battery rectifying circuit; the storage battery rectifying circuit is connected with a storage battery; the passive induction power-taken part is mounted on high-voltage electrical equipment; the inductive power-taken device is a plate condenser positioned in an alternating electric field. According to the invention, the mounting and maintenance are simple and convenient, the normal operation of a power network cannot be influenced, a power source doesn't need to be added, and the inductive power-taken high voltage power verifying displayer is suitable for working environment indoors and outdoors.

Description

technical field [0001] The invention relates to substation inspection equipment, in particular to an induction energy harvesting type high-voltage electric inspection display. Background technique [0002] In the current electric power stations, high-voltage electrometric displays are becoming more and more popular. Among them, the high-voltage electrometric displays that are more widely used are generally divided into three types: contact type, inductive type, and equipotential type. Among them, the contact type high-voltage electrometric display device The main body is composed of a ceramic capacitor as the mandrel, and the outer shell is made of epoxy resin or electric porcelain; it is based on the principle of capacitive voltage division, and provides the charged state information of the electrical equipment where it is installed; it is mostly used in 10-35kV high-voltage switch cabinets . The device is composed of a pillar porcelain insulator sensor, a display and a re...
