Title:
HIGH-TEMPERATURE CIRCUIT BREAK PROTECTION DEVICE FOR ELECTRICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/155942
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electrical apparatuses, in particular to a high-temperature circuit break protection device for an electrical apparatus. The high-temperature circuit break protection device comprises a box body, a refrigerator, and an electrical component, wherein a dust-proof net is fixedly mounted on a side wall of a left end of the box body, the refrigerator is fixedly mounted on a side wall of a right end of the box body, an exhaust fan is fixedly mounted on an upper end of the box body, and a radiator fan is fixedly mounted on an inner wall of a bottom end of the box body; and a mounting plate is fixedly mounted on an inner wall of the box body, a side wall of the mounting plate is provided with a strip-shaped hole, and the electrical component is fixedly mounted on a side wall of an upper end of the mounting plate. When the electrical component is overloaded and continuously gets hotter, and when a temperature measured by a temperature sensor exceeds the highest temperature, a controller supplies power to an electromagnet, the electromagnet generates an attraction force for an electrode plate II, one end of the electrode plate II is tilted and attracted to the electromagnet, the electrode plate II is separated from an electrode plate I, and a lead wire on the electrical component is broken, so that the electrical component stops operating, thereby preventing a long-lasting high temperature and overloaded operation from affecting the service life of an electrical apparatus.
