Title:
FULL-MODEL OVERVOLTAGE PROTECTION MODULE FOR ALTERNATING CURRENT CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2013/097590
Kind Code:
A1
Abstract:
A full-model overvoltage protection module for an alternating current circuit, integrating a first alloy-type temperature fuse (TCO1), a second alloy-type temperature fuse (TCO2), a third alloy-type temperature fuse (TCO3), a first varistor (MOV1), a second varistor (MOV2) and one type of gas discharge tube (GDT) into a modular structure. The first varistor (MOV1) and the second varistor (MOV2) between a live wire-ground wire (L-G) and a neutral wire-ground wire (N-G) in the module can effectively absorb a surging overvoltage. The first alloy-type temperature fuse (TCO1) and the second alloy-type temperature fuse (TCO2) close to the surface of the first varistor (MOV1) and the second varistor (MOV2) in the modular structure can effectively avoid fire hazards caused by varistor degradation/failure or a temporary overvoltage. The gas discharge tube (GDT) also radiates heat when the use process is abnormal, and the gas discharge tube (GDT) is also connected to the temperature fuse (TCO3) in series so that when the temperature of the gas discharge tube (GTD) is too high, the temperature fuse (TCO3) can disconnect the circuit. The full-model overvoltage protection module with the integrated structure and for the failure protection of the first varistor (MOV1), the second varistor (MOV2) and the gas discharge tube (GDT) can effectively prevent the fire hazards caused by degradation or failure of the first varistor (MOV1), the second varistor (MOV2) and the gas discharge tube (GDT).
