Disconnecting link state collecting device

Abstract

The invention discloses a disconnecting link state collecting device, which comprises a detecting sensor and an inductive attachment. A detecting sensor shell has a long strip structure and can be bent for deformation. The detecting sensor includes two magnetic sensing devices and a state collecting and output module; and the magnetic sensing devices are Hall elements and each magnetic sensing device corresponds to one position state. The magnetic sensing devices are connected with the state collecting and output module by wires. The state collecting and output module outputs a disconnecting link state signal after processing, wherein the signal output mode can be a hard contact mode or a communication mode. The inductive attachment includes an induction bracket and a permanent magnet-magnet steel; the induction bracket has a strip structure and the length and angle adjustment is made based on the actual structure and position of the disconnecting link; and the induction bracket is fixed at a disconnecting link mechanism by screws or hoops or a pasting way. The device has advantages of high detection precision, high safety and reliability, and strong engineering adaptability.

Description

technical field [0001] The invention relates to high-voltage power transmission system equipment of a grid, in particular to a knife switch state acquisition device. Background technique [0002] Isolation knife switch is a kind of electrical appliance often used in high-voltage transmission system. It is used to open and close the circuit. The basic principle and process of opening or closing the switch are: the motor is rotated by the control circuit, and the knife switch is driven by the corresponding transmission mechanism. The moving contact rotates and connects or separates from the static contact to realize the opening or closing of the isolation knife switch, and the auxiliary contact of the knife switch outputs the corresponding opening or closing signal. Its working principle and structure are relatively simple, but due to the large amount of use, the work reliability is required to be high. However, in the process of opening and closing, due to the reason of the ...
