Abstract

An embodiment of the invention provides a novel high-accuracy current transformer suitable for a GIS, belonging to the technical field of precise measurement of current. The GIS comprises at least onecurrent-carrying conductor and a protective shell, and the current transformer comprises multiple quantum sensors, and a quantum detection system, wherein the quantum sensor is used for measuring magnetic field strength around each current-carrying conductor, at least 4n quantum sensors are uniformly distributed on a virtual circle with a central axis of each current-carrying conductor as a center of a circle and preset length as radius, a magnetic shielding layer is arranged at the periphery of each virtual circle, wherein n is a positive integer, and the quantum detection system is connected with each quantum sensor, and is used for acquiring magnetic field strength around the current-carrying conductor through the quantum sensor, and calculating current of each current-carrying conductor according to the magnetic field strength.

Description

technical field [0001] The invention relates to the technical field of precise measurement of electric current, in particular to a novel high-precision current transformer suitable for GIS. Background technique [0002] GIS (Gas Insulated Switchgear, Gas Insulated Fully Enclosed Combined Electrical Appliance) is composed of circuit breakers, disconnectors, grounding switches, transformers, lightning arresters, busbars, connectors and outlet terminals, etc. These devices or components are all enclosed in metal grounding enclosures , filled with a certain pressure of SF inside 6 Insulating gas, so it is also called SF 6 Fully enclosed combined electrical appliances. [0003] With the continuous advancement of smart grid construction, traditional high-voltage electrical equipment is gradually developing in the direction of intelligence, modularization, miniaturization, multi-function and maintenance-free. The traditional electromagnetic current measurement device is difficul...
