Description
Technical field
The present invention relates to a kind of high-temperature superconductor resistor-type fault current limiter wall of high-temperature superconductor noninductive coil.
Background technology
Resistor-type high tc superconducting fault current limiter based on second generation belt material of high temperature superconduct is serially connected in electrical network, when normal operation, presents the no resistance state, on not impact of electrical network; When fault occured, the instant quench of high-temperature superconductor and present high resistance state and carry out current limliting had good application and market prospects.The core technology of this flow restricter is to utilize the noninductive double wrap disc coil of the second generation hts band coiling of having commercially produced, at present current techique is to utilize single or many superconductive tapes are made into noninductive disc coil, then is combined into the current limliting unit by a plurality of noninductive disc coil connection in series-parallel.The key technology of the noninductive disc coil of this double wrap is the wall of turn-to-turn.Because the quench resistance by second generation belt material of high temperature superconduct after fault occurs carries out current limliting, this process is attended by a large amount of Joule heat moment generations, the long-living larger terminal voltage at the two ends of current-limiting inductor, make turn-to-turn simultaneously, especially and around the end of biobelt produces high voltage.So the turn-to-turn wall plays the double action of High-Voltage Insulation and cooling duct.About the structure of turn-to-turn wall, present current techique is the corrugated arrowband that adopts insulating material to make, and the corrugated ribbon width is slightly wider than hts band, can play good cooling and High-Voltage Insulation effect (
Http:// www.superconductivityiea.org/whats-new-in-fault-current-limiters/notable-recent-accomplishment s; Patent: US2011/0116198A1).Because second generation hts band is ceramic coating material, enbrittle, the inevitably defective such as frangible, coil make with use procedure in, very easily damage and cause the superconduct performance to be degenerated." top of the waves " of the banded wall of above-mentioned ripple is that wire contacts with hts band, can make superconductive tape and wire contact position local pressure and bend, damages at the prestressing force of coil winding process; Current-limiting inductor by room temperature in the precooling process of liquid nitrogen temperature, thermal shrinkage stress also can make superconductive tape and wire contact position local pressure and bend, damages; In the failure current limit process, the moment electromagnetic action under huge over-current shock also can make superconductive tape and wire contact position local pressure and bend, damages.
Summary of the invention
The objective of the invention is to overcome the defective of very easily damaging the brittle ceramic hts band in the coiling at coil, cold cycling and the over-current shock process that prior art exists, propose a kind of biobelt and around the wall of noninductive disc coil.The present invention can effectively overcome the problem and blemish that above prior art exists, and also has a processing and fabricating simple, and production efficiency is high, has good cooling and High-Voltage Insulation effect under the service conditions of immersing in liquid nitrogen.
