Abstract

The invention discloses a circuit protection structure with double temperature induction switching-off, which comprises a cover body, a thermal induction trip device, a thermal fusion switching-off device and a seat body. Two temperature induction switching-off devices which run independently are arranged between the two terminals of a circuit loop. At the time of current overload, circuit overheating or overhigh environmental temperature, a contact spring piece of the thermal induction trip device is heated, deformed, bent in a reverse direction, tripped and switched off (OFF); at the time ofthe current overload, the circuit overheating or the overhigh environmental temperature, the fusible alloy of the thermal fusion switching-off device is fused and ruptured when no reaction, an incomplete reaction or repeated OFF and ON occur in the thermal induction trip device and the temperature of the circuit loop is continuously risen, and the complete OFF of the circuit loop is ensured. Thetwo independent temperature induction switching-off devices have double temperature induction switching-off effects and ensure the aim of safe power utilization.

Description

technical field [0001] The invention relates to a circuit protection structure, in particular to a circuit protection structure with double temperature induction power-off. Background technique [0002] The use of electricity is an indispensable part of modern human society. All kinds of electrical products and equipment surround our lives, especially computerized and informationized industries, homes, transportation, education, entertainment, etc., are impossible without electricity. In contrast, the safe use of electricity is something that modern people cannot but be cautious about. [0003] Generally speaking, there is a main switch for power control in the overall circuit circuit that provides electricity. Usually the main switch is in the ON state, and a fuse or a breaker is set on it. When too many electrical appliances used in the circuit circuit cause current In the event of overload, short circuit, overheating of the circuit, etc., the fuse will blow or the circui...
