Example Embodiment
[0032] Example one
[0033] according to figure 1 As shown, the present embodiment proposes a system of a rotor slide ground deterioration warning, including a connection detection system, a closing enable system, an actual value acquisition medium, a threshold comparison conversion system, and an early warning processing output system, the connection detection The system is used to connect the left and intermediate phases of the three-phase change 170V power supply, and provide a 220V drive voltage to provide a driving power supply for the detection system; the hinge enable system for triggering the system closing signal, connects three-phase communication and two phases. DC, then trigger the system enable signal, drive the entire rotor slip ring system into normal rotational cycles; the core of the connection detection system is to detect after the connection, the logical order and logical relationship of the entire subsystem is very important because of the design of the entire...
Example Embodiment
[0039] Example 2
[0040] according to figure 2 As shown, the present embodiment proposes a method of a rotor slide ground deterioration warning, including the following steps:
[0041] Step 1: Start the connection detection system, the left side of the three-phase change 170V power supply;
[0042] Step 2: Provide 220V drive voltages using the connection detection system, providing a drive power supply for the detection system;
[0043] Step 3: Start the closing enable system, trigger the system closing signal, perform system closing, connect three-phase communication with two-phase DC, system closing is the connection link of the entire system, system closing is maintenance and production Two different states are taken from the circuit system, thereby performing switching control according to the working conditions; the design of the switch control according to the working conditions can ensure that the slip ring system does not have electricity when the maintenance is maintaine...
