The invention discloses an asynchronous motor fault diagnosis box, and relates to the technical field of motor diagnosis. A mounting rack is mounted inside a box body; a damping plate spring is mounted at the upper end of the mounting rack; damping springs are mounted at two ends of the damping plate spring; a voltage navigation plug and a current navigation plug are respectively connected with a sensor plate; the sensor plate is connected with one end of a detection relay coil through a lead; the other end of the detection relay coil is connected with an acquisition card through another lead; the acquisition card is connected with a tablet computer mounted on the box body through another lead; an UPS (Uninterrupted Power Supply) is connected with one end of a main power supply switch through another lead; the other end of the main power supply switch is connected with one end of each of a power supply module and a normally closed contact of a detection relay; and the other end of the normally closed contact of the detection relay is connected with an alarm. By adopting the asynchronous motor fault diagnosis box, the service life can be prolonged, real-time detection on current and voltage can be achieved, and self inspection of equipment can be achieved.
Description
technical field [0001] The invention relates to a fault diagnosis box for an asynchronous motor, which belongs to the technical field of motor diagnosis. Background technique [0002] In the analysis experiment of the running state of small and medium-sized three-phase asynchronous motors, current and voltage are the few important data that can be directly measured. Especially in the process of designing, modifying, monitoring, and experimenting electrical equipment, voltage and current data are the most important parameters. At present, the trend of asynchronous motor monitoring technology is to use the analysis of the three-phase voltage and three-phase current signals of the motor to estimate the real-time operating status of the motor and diagnose common faults of the motor. However, when the existing diagnostic box is used on the spot, its measurement data is inaccurate, and it is easily damaged and has a short service life. Contents of the invention [0003] In vie...
