Problems solved by technology

1. Caused by lightning strike; 2. Caused by power grid operation; 3. Caused by nuclear explosion
The hysteresis of the varistor has a great influence on the clamping effect of the surge voltage
Due to the slow response time of the varistor, the subsequent circuit will be damaged by the surge; when the surge energy exceeds the maximum capacity of the varistor, the varistor will fail; the varistor can generally only protect energy below 4KV, and for surges above 4KV The protective effect is not ideal

Embodiment Construction

[0012] Such as figure 1 As shown in the figure, a switching power supply with high surge protection level includes a resin tank and an upper roller and a lower roller arranged above the resin tank. , the right side of the lower roller is provided with a roller, the bracket is provided with a beam, one end of the beam is installed on the bracket, and the other end of the beam is connected to the roller; the beam is provided with a roller adjustment hole.

[0013] Adjustment holes are provided on the bracket, and the contact condition between the lower roller and the molding resin can be adjusted in time without adding molding resin.

[0014] A crossbeam is added to the bracket and a number of roller adjustment holes are opened on the crossbeam, which can adjust the contact tightness between the roller and the lower roller and the tension formed by the roller to the lower roller. It is connected with the bracket and can be replaced at any time .

[0015] There is a roller on t...

Abstract

The invention discloses a power source comprising a resin tank and upper and lower rollers arranged above the resin tank. The upper roller and the lower roller are mounted on a bracket which is provided with adjustment holes. A rolling shaft is arranged at the right side of the lower roller. A beam is arranged on the bracket. One end of the beam is mounted on the bracket, and the other end of the beam is connected with the rolling shaft. The beam is provided with rolling shaft adjustment holes. According to the invention, the rolling shaft is added at the right side of the lower roller to scrape molding resin adhered to the lower roller so as to make the molding resin on the lower roller more uniform; both the upper roller and the lower roller are mounted on the bracket, and the bracket which is provided with a plurality of adjustment holes, so that the distance between the lower roller and the molding resin surface can be adjusted according to the oil content of the molding resin in the resin tank; and the beam is provided with rolling shaft adjustment holes, so that on one hand, the degree of matching between the roller and the rolling shaft can be adjusted, and on the other hand, the rolling shaft is easy to replace.

Description

technical field [0001] The invention relates to surge protection technology, in particular to a power supply. Background technique [0002] Generally speaking, a surge is an overvoltage, which will cause fatal damage to the switching power supply of electronic equipment. The modified voltage generally comes from three aspects. 1. Caused by lightning strike; 2. Caused by power grid operation; 3. Caused by nuclear explosion. The hysteresis of the varistor has a great influence on the clamping effect of the surge voltage. Due to the slow response time of the varistor, the follow-up circuit will be damaged by the surge; when the surge energy exceeds the maximum capacity of the varistor, the varistor will fail; the varistor can generally only protect energy below 4KV, and for surges above 4KV The protective effect is not ideal. Contents of the invention [0003] The invention aims at the deficiencies of the prior art and provides a switching power supply with high surge pro...
