1) Visualization of the resources of the generator and asynchronous motor;
2) Wireless data transmission;
3) Non-contact version of the device.
SYSTEM FEATURES:
- Detailed monitoring visualization by presenting the remaining life of the induction motor as a percentage.
Ability to monitor high voltage high power motors.
- Absence of external moving parts complicating operation. The device is assembled in a non-contact version.
- Ability to transfer information both wirelessly via Bluetooth interface, and traditional wires.
- No need for external power supply; The supply voltage is taken directly from the phase conductor by means of a built-in transformer.
- The device monitors the motor only when it is turned on and automatically turns off when it is turned off.
- Reliable fixation of the device on the phase wire by means of tight clamps.
THE PRINCIPLE OF OPERATION:
The current sensor located in the device records the current characteristic of the load on the phase wire of the electric motor, after which it is analyzed.
During this analysis, one type of damage is detected:
- Defects of the rotor cage;
- Bearing defects;
- Inter-turn short circuits in the stator winding;
- Deviations of the air gap.
When detecting the development of any of the defects, the system displays information about this defect in percentage form for ease of visualization. This information can be transmitted either via a radio channel to the automated process Control System for further storage and processing, or transmitted to a smartphone or tablet.
STRUCTURAL DESIGN:
The device of the monitoring system is made in a sealed cube-shaped housing with clamping clamps, for ease of installation on the phase wire of the asynchronous motor and exclusion of mixing as a result of operation, as well as to ensure proper insulation. The proposed range of devices includes models for different categories
of electric motor capacities and different voltage classes; for voltages of 0.4, 6, 10 kV and capacities from 2 to 20 kW.
