Detailed Description

In the embodiment shown in fig. 1, the motor junction box is divided into two areas, namely the external connection area 7 and the equipment area 1, by the partition plate 8, and the two areas are separated by the partition plate 8. The external wiring area 7 is internally provided with three external wiring terminals X4, X5 and X6 for connecting a three-phase power supply; the device area 1 is internally provided with a current and voltage detection module 2, a temperature detection module 3, a winding insulation detection module 4 and a data processing and transmission module 5, and of course, a vibration detection module is preferably further arranged, wherein the temperature and vibration detection sensor is directly embedded in a proper position in the junction box, X1, X2 and X3 are three winding outgoing line terminals, the three winding outgoing line terminals respectively penetrate through a partition plate 8 by leads to be connected with three external terminals X4, X5 and X6, the leads need to be insulated and sealed when penetrating through the partition plate 8, and simultaneously the leads also penetrate through three current transformers 61, 62 and 63, so that the current transformers can detect the current of the motor.

The current signals of the current and voltage detection module 2 are taken from three current transformers 61, 62 and 63, and the voltage signals are directly taken from three winding lead-out terminals X1, X2 and X3, and power of each module is supplied by the voltage signals. The detection end of the winding insulation detection module 4 is connected with one winding leading-out terminal X1, so that whether the terminal is electrified or not can be detected to determine when the motor winding insulation is detected, and the insulation detection needs to be carried out when the motor is powered off and stopped, so that the battery B1 is arranged to supply power to the insulation detection module 4 and the data processing and transmission module 5 when the motor is stopped.

Therefore, when the motor is powered on, the utility model can detect parameters of the motor such as current, voltage, temperature, vibration and the like; when the motor is stopped in power failure, the insulation of the winding can be detected. After detection, the data is analyzed by a data processing and transmitting module 5, and the result is wirelessly transmitted to a control center.

In fig. 2, 9 is a cover of the device area, 10 is a cover of the external wiring area, and the two areas are respectively provided with a cover plate, so that the cover 10 of the external wiring area can be opened only when the motor is connected, in order to avoid signal shielding, a window 11 is opened on the cover 9 of the device area, the inside of the window corresponds to an antenna on the data processing and transmission module 5, and the window 11 is covered by a non-metallic material, so that the dust is prevented, and radio signals are not shielded.

Because the utility model provides a motor terminal box has realized external connection and equipment subregion, has both made things convenient for the wiring and has protected inside accurate detection module again, simultaneously, still each detection module can detect the various parameters in the motor operation to can upload control center in real time with data is automatic, be convenient for in time discover and handle trouble hidden danger, improve motor operational reliability.
