Abstract

The invention discloses a surge protection device having an arc extinction function implemented by a high performance arc shield. The surge protection device includes the arc shield, a propeller body, an elastic element, a voltage sensing assembly, an electrode pin, a housing and a thermal switch assembly including a thermal-sensitive element. The thermal-sensitive element is in close thermal coupling with the voltage sensing assembly. When constant heating and temperature rise of the voltage sensing assembly is caused because of failure short circuit current due to elements such as instant surge overvoltage and the like in a line, pop-up disengagement of the thermal switch assembly is achieved due to a thermal coup0ling responding action of the thermal-sensitive element. Complete arc extinction is performed by the arc shield and potential fire hazards of an electric device are avoided effectively.

Description

technical field [0001] The invention relates to a circuit protection device, in particular to a surge protection device with a high-performance arc-proof cover for arc extinguishing. Background technique [0002] Surge protector or surge suppressor (surge suppressor), also known as surge protection device, is a device that provides overvoltage safety protection for various sensitive or expensive electronic equipment, such as electronic components on computers and communication-related equipment. protective device. The varistor commonly used in existing surge protection devices is an electronic device composed of zinc oxide particles and complex intragranular particle materials. It is a voltage nonlinear device, and its unique voltage and current characteristics are ideal for sensitive electronic circuits. Devices, but its material composition determines that it is easy to deteriorate and catch fire when it is over-voltage, short-circuited and overloaded, causing catastrophi...
