Embodiment 1
[0021] The technical solution of embodiment 1: a shallow groove is engraved on the upper part of the non-metallic hollow long container. When the fluid is vaporized, the groove ruptures and the gas is ejected to realize the cut-off protection.
Embodiment 2
[0022] Example 2, the technical solution of the present invention can be further improved as follows: the shallow groove is a large-diameter pressure valve, and it can be re-worked as long as it is filled with ionic fluid during recovery.

The invention discloses a water-cooled type high-current self-destruction protection cable, which is characterized in that the protection cable is a high-current cable filled with guide ion fluid; a shallow carving groove is carved on the upper part of a long nonmetallic and hollow container; and the fluid vaporizes during overcurrent, the carving groove is broken, and gas spouts to realize cutoff protection. According to the embodiment of the invention, the technical scheme of the protection cable can be improved, namely the shallow carving groove is a large-caliber pressure valve, and the pressure valve can operate again only by filling the ion current during restoration.
Description
technical field [0001] The invention relates to electrical components of a power system, in particular to a self-explosive protective cable. Background technique [0002] In the power system, high-current cables use a large amount of copper and are not easy to install. The applicant applied for a water internally cooled high-current self-explosive protection cable, that is, a high-current cable with internal ionic fluid conduction. When working with high current, the voltage is often not the main problem, but the overcurrent protection needs to be solved. The temperature rise of the contacts of the circuit breaker with high current is very large, and the energy consumption is severe. Contents of the invention [0003] The technical problem of the present invention is to realize the protection by using a high-current cable guided by the ionic fluid in the content. [0004] A supplementary introduction of a high-current cable with ionic fluid conduction. Its practice is ...
