A replaceable and improved high-voltage resistor

Abstract

The invention relates to a replaceable improved high-voltage resistor which comprises an insulating sleeve and a conductive assembly, a conductive carbon filling layer is arranged in the insulating sleeve, the conductive assembly and the insulating sleeve are detachably arranged, the conductive assembly comprises a copper wire and a mounting hole, the copper wire is sleeved with an insulating column, and the insulating column is movably inserted into a potting layer; in the high-voltage resistor, the insulating sleeve and the conductive assembly are detachably arranged; in this way, in actualuse, copper conductor fracture, or the insulation sleeve is damaged; through replacement of one of them, a reuse effect can be realized, in this way, damage to one of the insulation sleeve and the copper wire in the prior art can be avoided; the whole resistor cannot be used, the cost for replacing one of the insulation sleeve and the copper wire is lower than that of the whole resistor, and meanwhile, undamaged parts are continuously used, so that the effect of saving resources can be achieved, and the production cost is fundamentally reduced.

Description

technical field [0001] The invention relates to the technical field of resistors, in particular to a replaceable improved high-voltage resistor. Background technique [0002] Resistance (usually denoted by "R") is a physical quantity, which in physics indicates the magnitude of the resistance of the conductor to the current. The greater the resistance of the conductor, the greater the resistance of the conductor to current flow. Different conductors generally have different resistances, and resistance is a characteristic of the conductor itself. Resistance will cause a change in the flow of electrons, the smaller the resistance, the greater the flow of electrons, and vice versa. Superconductors have no resistance. [0003] Existing resistors all use insulating sleeves and copper wires, as well as built-in carbon fillers arranged in the insulating sleeves, and the insulating sleeves and copper wires are connected by welding, so that after the copper wires and insulating sl...

AI Technical Summary

Problems solved by technology

[0003] Existing resistors all use insulating sleeves and copper wires, as well as built-in carbon fillers arranged in the insulating sleeves, and the insulating sleeves and copper wires are connected by welding, so that after the copper wires and insulating sleeves are broken, , which leads to the fact that the resistor can no longer be used, especially for some specific high-voltage resistors, if a resistor cannot be used, high costs will be incurred during production, thereby increasing production costs
