Abstract

The invention relates to the technical field of electronic safety protection devices, and particularly discloses a safe disconnecting device for MOV module temperature alloy. An MOV module comprises an MOV chip, a disconnecting cavity, a temperature alloy plate, a cutter, a spring and an MOV module lead-out electrode. According to the provided safe disconnecting device for the MOV module temperature alloy, a process of connection of an MOV chip lead-out pin, a temperature welding point (low-temperature alloy) and a pressure-sensitive module lead-out pin in the prior art is changed into connection of the temperature alloy plate and the MOV module lead-out electrode, temperature transmission loss is reduced, and disconnecting reliability is improved; the temperature alloy plate can be directly connected with the MOV chip, heated area is increased, direct heating is implemented, temperature transmission loss is reduced, and disconnecting reliability and accuracy are improved; and the flattemperature alloy plate facilitates impulse current pass (skin effect) and residual voltage reduction, so that the device has a temperature protection function and a pulse current overload protectionfunction.

Description

technical field [0001] The invention relates to the technical field of electronic safety protection devices, in particular to a safety release device for MOV module temperature alloys. Background technique [0002] Existing pressure-limited varistor modules (or SPD surge protectors) have special nonlinear current-voltage characteristics. Once abnormal conditions occur during use, such as lightning strikes and electromagnetic field interference, the power switch operates frequently and the power system fails, making the The voltage on the line increases suddenly, exceeding the conduction voltage of its piezoresistor and entering the conduction region. At this time, the current (I) and the voltage (V) have a nonlinear relationship, which is generally called a nonlinearity parameter (Nonlinearity Parameter), and its value can reach tens. At this time, the impedance of the piezoresistor will become lower, and the resistance value is equivalent to a few tenths of ohms, allowing ...
