Title:
HIGH TEMPERATURE SUPERCONDUCTING HYBRID CURRENT LIMITER
Document Type and Number:
WIPO Patent Application WO/2017/193982
Kind Code:
A1
Abstract:
A high temperature superconducting hybrid current limiter, comprising a group of high temperature superconducting modules (100), a current on-off valve (200), an elastic connecting device (300), a current limiting circuit (400), and a group of current leading-in terminals (500). The group of high temperature superconducting modules (100) comprises a first high temperature superconducting module (101) and a second high temperature superconducting module (102) which are disposed side by side. One end of the current on-off valve (200) is connected with the first high temperature superconducting module (101), and the other end thereof is connected with the second high temperature superconducting module (102). One end of the elastic connecting device (300) is connected with the first high temperature superconducting module (101), and the other end thereof is connected with the second high temperature superconducting module (102). One end of a first current leading-in terminal (501) of the group of current leading-in terminals (500) is connected with the first high temperature superconducting module (101), and the other end thereof is connected to one end of the current limiting circuit (400). One end of a second current leading-in terminal (502) is connected with the second high temperature superconducting module (102), and the other end thereof is connected with the other end of the current limiting circuit (400). The current limiter can automatically suppress a fault current when the fault current occurs in a power grid, is high in automation degree, flexible in use, simple in structure, and small in size, and can be widely applied.
