Embodiment Construction

[0011] Please refer to FIG. 1 , which is a schematic circuit diagram of a piezoresistor assembly with an over-temperature release mechanism according to the present invention. As shown in Figure 1, the varistor assembly is composed of a varistor body 20 and an over-temperature release mechanism 30, and the first pin 1 and the second pin 2 can be connected in parallel to the L phase (i.e. live wire 11) and Between the phase N (namely the neutral line 12 ), the second pin 2 and the third pin 3 can be connected in series on the L phase (ie the live line 11 ). The first wire can also be the live wire 11 , the neutral wire 12 and the ground wire 13 , and the second wire can be the live wire 11 , the neutral wire 12 and the ground wire 13 which are not repeated on the first wire. The first pin 1 of the piezoresistor body 20 can be coupled to the neutral line 12, the second pin 2 of the piezoresistor body 20 and the third pin 3 of the over-temperature release mechanism 30 are connect...

Abstract

The invention is concerned with an assembly of excessive temperature release framework and varistor, whose release framework connecting with the second and third leading feet made of varistor and super-temperature release framework. The two poles on both surfaces of varistor melts with the first and second leading foot, and the top of the second leading foot owns a heat-leading dot projecting out of the insulation coating to varistor. The excessive temperature release framework is made up of elastomer, protecting shell, meltable metal and the third leading foot connecting with elastomer. When elastomer melts to the heat-leading dot to the second leading foot of varistor, the framework is a pathway and the second and the third feet are communicated. When the high temperature of varistor caused by over voltage and over current will melt the meltable metal of the heat-leading dot, and the framework will flick with the instantaneous spring of elastomer and reach the safeguard by the turnoff of the second and the third leading feet.

Description

technical field [0001] The present invention relates to a surge absorber (varistor), especially a surge absorber (varistor) with an over-temperature release mechanism. Background technique [0002] The surge absorber alias varistor (also known as varistor) (Varistor) is simplified from the combination of VariableResistor. Common varistors include silicon carbide (SiC), silicon Zener Diode (Si Zener Diode), and Zinc oxide (ZnO) three. Early scientists discovered that the ceramic two-electrode varistor made of zinc oxide powder sintered at high temperature has a nonlinear resistance change to voltage. It has a high resistance value at low voltage and can prevent the flow of current. At high voltage, its resistance value rapidly drop, allowing a large amount of current to pass through. [0003] The working principle of the surge absorber (varistor) Zinc oxide is a metal oxide, so it is also called metal oxide varistors (Metal Oxide Varistors, MOV's). When the internal additi...
