Abstract

The invention relates to the technical field of motor preparation, in particular to a motor dead point and voltage resistance detection all-in-one machine comprising a workbench, a voltage-resisting instrument, a dead point measuring device, a circuit changing tool and a controller, a contact probe is arranged on the workbench, the high-voltage end of the voltage-resisting instrument is electrically communicated with the contact probe, the dead-dead-measuring device comprises a rotating speed measuring mechanism, the circuit changing tool comprises a voltage-resisting end communicated with a ground wire of the voltage-resisting instrument, a dead-point-measuring end which is communicated with the output end of the dead-dead-measuring device, a switching element which can be electrically communicated with the voltage-resisting end and the dead-point-measuring end respectively, and a driver which drives the switching element, the switching element is electrically communicated with a power line of a motor, and the controller is in communication connection with the driver. According to the arrangement, when the dead point and the voltage resistance of the motor are detected, the two procedures of measuring the dead point and the voltage resistance are combined into one procedure, so that the manual operation time is greatly shortened, the working efficiency is improved, and the effect of reducing staff to improve efficiency is facilitated.

Description

technical field [0001] The present application relates to the technical field of motor preparation, and more specifically, to an integrated machine for detecting motor dead point and withstand voltage. Background technique [0002] The DC built-in board motor needs to test the dead point of the motor to check whether the motor can start normally under low voltage, and also needs to measure the withstand voltage of the motor to measure whether the motor leaks under high voltage to ensure safe operation. At present, the two processes of testing the dead point of the motor and measuring the withstand voltage of the motor are operated by two people separately, and the process of measuring the dead point takes a long time. Most of the employees wait for the motor to be measured, which greatly wastes working time. resulting in low work efficiency. [0003] When measuring the withstand voltage value of the motor, a high-voltage DC power supply is provided, and the voltage value is...

Problems solved by technology

At present, the two processes of testing the dead point of the motor and measuring the withstand voltage of the motor are operated by two people separately, and the process of measuring the dead point takes a long time. Most of the employees wait for the motor to be measured, which greatly wastes working time. resulting in low work efficiency

[0003] When measuring the withstand voltage value of the motor, a high-voltage DC power supply is provided, and the voltage value is as high as 1800V. When measuring the dead point of the motor, 36V or 24V DC is used. The difference between the two is huge. ACCIDENT

[0004] Therefore, how to solve the problem that in the existing technology, the dead point of the motor and the withstand voltage are manually tested by two processes, the manual test takes a long time, and the work efficiency is low, is a key technical problem to be solved by those skilled in the art
