Abstract

The invention discloses a production method of a resistor, and relates to the technical field of electrical equipment manufacturing. The production method comprises the following steps of sleeving insulating sleeves on the outer sides of two support rods respectively, inserting a first resistor disc at one end of each insulating sleeve, sleeving metallic beads on the outer sides of the insulating sleeves, allowing a contact surface at one end of each metallic bead to push against one side contact surface a contact surface at one sideof each resistor disc, inserting a second resistor disc on the insulating sleeves at the other end of each metallic bead, allowing the first resistor discs first resistor disc to be connected in parallel with the second resistor discs second resistor disc by the metallic beads, allowing third resistor discs third resistor disc to be connected in parallel with fourth resistor discs fourth resistor disc by the metallic beads, allowing the first and second resistor discs to be connected in series with the third and fourth resistor discs, and repeat in this way until the resistor is produced. The production method can solve the problem of short-circuit trip caused by frequent burnout of the contact surfaces of the operation maintaining resistors and grounding arising from burnout and breakdown of the insulating sleeves of motor rotors.

Description

technical field [0001] The invention relates to the technical field of electrical equipment manufacturing, in particular to a method for producing a resistor used for retaining running resistance of a rotor of a high-voltage wound AC motor. Background technique [0002] Due to the working environment and nature of the crusher, the reserved running resistance of the high-voltage wound AC motor rotor winding of the mine crusher is determined by the working environment and nature of the crusher. The impact is very large, and through mechanical action on the high-voltage main motor shaft, the impact load current of the main motor is very large. Often due to large changes in the crushing load, the contact surface of the motor rotor retaining running resistance is frequently burned out, and the insulating sleeve is burned out and grounded to cause a short-circuit tripping fault. Contents of the invention [0003] The purpose of the present invention is to provide a method for p...
