Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically to a testing device for the electrical insulation strength of motor stator. Background Technology

[0002] Insulation strength refers to the maximum ability of an insulating material to withstand an electric field without breakdown, usually expressed in kilovolts per millimeter (kV / mm). The electrical insulation strength of a motor stator is a core indicator for measuring the reliability of its insulation system, mainly involving factors such as the material's voltage withstand capability, structural design, and environmental adaptability. During the testing process, operators need to connect multiple wires to the motor stator for testing. In the process of wiring, operators inevitably need to rotate or move the motor stator, resulting in high labor intensity. Therefore, it is necessary to design a motor stator electrical insulation strength testing device that can reduce labor intensity. Summary of the Invention

[0003] The purpose of this invention is to provide a test device for the electrical insulation strength of motor stator, which has the advantage of reducing labor intensity.

A support plate is rotatably installed at the top of the support platform.

[0006] Preferably, the upper end of the support platform is provided with a protective cover, and a sliding door is slidably provided on the upper end of the protective cover.

[0013] 2. This utility model utilizes a double-pole double-control switch, requiring the operator to press both buttons of the double-pole double-control switch with both hands to control the electric telescopic rod to close the sliding door, thus avoiding the safety risk of the operator's hands remaining inside the protective cover.

[0020] Example 1: A motor stator electrical insulation strength testing device includes a chassis 1, inside which a testing component is installed. The testing component is existing technology and will not be described in detail here. A support platform 2 is installed at the front end of the chassis 1 to support the motor stator. An operation panel 3 and a display 4 are installed at the top of the chassis 1. Both the operation panel 3 and the display 4 are connected to the testing component. The display 4 is used to display the test results.

[0021] A vertical plate 5 is provided in the middle of the support platform 2. Both the vertical plate 5 and the side wall of the chassis 1 are provided with multiple terminals 6 that are connected to the test components. A support plate 7 is rotatably provided at the upper end of the support platform 2. Each terminal 6 is located on the side of the support plate 7. The support plate 7 is used to support the motor stator. The motor stator is placed on the support plate 7, and the motor stator is connected to each terminal 6 by rotating the support plate 7. This avoids manually rotating or moving the motor stator during the wiring process and reduces labor intensity.

A controller 12 is installed on the support platform 2. The controller 12 is connected to both the infrared distance sensor 10 and the test component. The controller 12 controls the test component to be powered on by measuring the position of the sliding door 9 through the infrared sensor. The test component can only be activated when the sliding door 9 is in contact with the protective cover 8, thus preventing the operator's hand from being left inside the protective cover 8 and ensuring high safety.
