A low temperature current transformer coil

Abstract

A low-temperature current transformer coil, the low-temperature current transformer coil mainly includes a low-temperature glue inner skeleton (1), a low-temperature insulating wire turn (2) and a low-temperature glue outer skeleton (3); the low-temperature glue inner skeleton ( 1) Located in the center of the low temperature current transformer coil, it is a hollow ring structure; the low temperature insulated wire turns (2) are formed by winding low temperature resistant insulating enameled wire along the radial direction of the low temperature rubber inner skeleton (1); the low temperature insulated wire turns (2) ) lead-out wires (23) close to the outer wall of the low-temperature rubber inner skeleton (1) and lead out from the loop groove (12) on the outer wall of the low-temperature rubber inner skeleton (1); the low-temperature rubber outer skeleton (3) is ring-shaped, and the The low-temperature insulated wire turns (2) and the low-temperature glue inner skeleton (1) outside the lead-out wire (23) are covered.

Description

technical field [0001] The invention relates to a low-temperature current transformer coil applied to superconducting power equipment. Background technique [0002] Thanks to the development of superconducting materials, the research on superconducting power devices has also made great progress in recent years, and some devices have been applied to actual power grids. Similar to conventional power equipment, the windings of superconducting power equipment such as superconducting transformers, superconducting current limiters, etc. run. In order to obtain the shunt status of parallel superconducting windings under steady state, overcurrent impact and other conditions, the current of superconducting windings must be measured at -200°C. [0003] The biggest problem brought by low temperature to the transformer is the damage to the structure and insulation of the transformer. For example, transformers made of conventional plastics or ordinary epoxy will crack due to thermal e...
