Abstract

The invention discloses an insulation performance detection device for a high-voltage motor. The insulation performance detection device comprises a bottom plate, a movable plate, the high-voltage motor, a megger, rubber suction cups and a ferromagnetic enclosure frame, wherein the movable plate is mounted at the top part of the bottom plate, the high-voltage motor is mounted at the top part of the movable plate, and the megger is mounted at the top part of the bottom plate; the ferromagnetic enclosure frame is mounted at the top part of the bottom plate; and the top part of the megger is provided with four sets of the rubber suction cups arranged in a square shape, the top parts of the rubber suction cups are provided with supporting columns, and the top parts of the supporting columns are provided with square plates. Data of a dial plate of the megger can be captured through using a recorder and then backed up and stored, the to-be-measured motor on the moving plate has a fixed and anti-moving function when placed, and the distance between the motor and the megger can be changed, so that the distances between the motors of different sizes and the megger can be within the effective length range of a measuring flexible wire, when the insulation performance detection device detects, magnetic field isolation can be carried out, and the influence of a magnetic field of an external component on a detection result is avoided.

Description

technical field [0001] The invention relates to the technical field of high-voltage motors, in particular to an insulation performance detection device for high-voltage motors. Background technique [0002] High-voltage motors refer to motors with a rated voltage above 1000V, which have the advantages of high power and strong impact resistance, but high-voltage motors need to undergo a series of tests before they are put into use, and they can only be put into use after they pass. The detection device performs insulation detection on it. There are two main types of motor insulation measurement, one is the insulation of the winding to the ground, and the other is the insulation between the phases of the winding. The megger is required during the test. [0003] The defective that existing insulation performance detection device exists is: [0004] 1. The comparative document CN108594138A discloses an insulation performance testing device for charging treasure, "including a wo...
