Dielectric insulation magnetic pole spiral arc resistance processing technology

Abstract

The invention discloses a dielectric insulation magnetic pole spiral arc resistance processing technology, the dielectric insulation magnetic pole spiral arc resistance processing technology is as follows: an electrode is arranged on the main body of an electronic component, the electrode is in a spiral line shape, when a current passes through the electrode, an axial magnetic field perpendicular to the surface of the electrode of a chip, and Lorentz force produced by the axial magnetic field enables electrons in the body of the chip to move in a spiral forward way. Leading wire terminals are disposed in a central area, the current finally reaches the center area, the surface current density in the center declines greatly, the field intensity between the leading wire terminals is weakened, and an arc is difficult to form by the center between the two leading wire terminals at the central position. In experiments, a spiral MOV not only has 3 to 4 times higher of energy absorption capacity, and also shows the thermal melt breakdown resistance of the MOV. The continuous overvoltage-resistant temperature of the spiral MOV reaches 1.7 to 2.0 times of that of a straight line L type leading wire piezoresistor, and the temperature reaches to the temperature of 150-174 DEG C, and is completely beyond the general level of the industry.

Description

technical field [0001] The invention discloses an anti-arc method, in particular to a dielectric insulation magnetic pole spiral anti-arc treatment technology. Background technique [0002] 1. The arc burning of the varistor MOV caught fire [0003] 1. MOV arcing fire has always been a headache for the varistor manufacturing industry. The main reason for the arcing fire is: the starting current of the varistor can start work / arcing at the mA level, and the electrical circuit All the fuses inside are disconnected when the working current of the fuse is disconnected, and the disconnection protection is started at the level of ampere A, so the operating overvoltage generated in the circuit itself (especially the circuit with inductive circuit vacuum breaking in the circuit such as frequency conversion The circuit makes it easier to generate) to form a continuous resonant voltage, which can make the varistor start to work, and the power frequency current of the circuit at this ...
