Abstract

The invention relates to a magnetic field protection method and device for a dry-type hollow bridge arm reactor and a protective fence. Comprising the following steps: respectively applying an excitation signal to each encapsulation layer of the dry-type hollow bridge arm reactor; and analyzing by using a preset finite element two-dimensional magnetic field model corresponding to the dry-type hollow bridge arm reactor to obtain magnetic field distribution state information of the current dry-type hollow bridge arm reactor; then performing further analysis in combination with the magnetic field distribution state information to obtain distance information and height information of the protective fence set when the influence on the health of the user is small, and finally building the protective fence in combination with the distance information and the height information. According to the scheme, the protective fence can be built around the dry-type hollow bridge arm reactor according to the actual magnetic field distribution state of the dry-type hollow bridge arm reactor to prevent a user from getting close to the dry-type hollow bridge arm reactor, so that the influence of the magnetic field of the dry-type hollow bridge arm reactor on the health of the user is effectively reduced, and the use safety performance of the dry-type hollow bridge arm reactor can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of power grid safety, in particular to a method, device and protective fence for protecting a dry-type air-core bridge arm reactor from a magnetic field. Background technique [0002] Long-distance large-capacity flexible DC or hybrid DC transmission technology has been applied in engineering, marking the arrival of a new generation of intelligent DC transmission era. In long-distance large-capacity flexible DC or hybrid DC power transmission projects, each flexible DC converter valve bridge arm needs to use a bridge arm reactor as an important device for controlling the quality of transmitted power, limiting the circulating current of the bridge arm, and limiting the system fault current. Due to the requirement to keep the inductance value stable and undistorted under a large proportion of AC and DC mixed currents, the preferred design of large-capacity bridge arm reactors in existing projects is ...
