Embodiment 1
[0033] according to figure 1 As shown, this embodiment proposes a system for early warning of ground degradation of rotor slip rings, including a connection detection system, a closing enabling system, an actual value acquisition middle end, a threshold value comparison conversion system, and an early warning processing output system. The system is used to connect the left phase and the middle phase of the three-phase alternating 170V power supply, and provide 220V driving voltage to provide driving power for the detection system; the closing enabling system is used to trigger the closing signal of the system, and connect the three-phase AC and two-phase DC, and then trigger the system enable signal to drive the entire rotor slip ring system into a normal rotation cycle; the core of the connection detection system is to connect first and then detect. The logical sequence and logical relationship of the entire subsystem are very important, because in the design of the entire cir...
Embodiment 2
[0040] according to figure 2 As shown, this embodiment proposes a method for early warning of ground degradation of the rotor slip ring, including the following steps:
[0041] Step 1: Start the connection detection system and connect to the left phase and the middle phase of the three-phase alternating 170V power supply;
[0042] Step 2: use the connection detection system to provide 220V drive voltage, and provide drive power to the detection system;
[0043] Step 3: Start the closing enabling system, trigger the closing signal of the system, close the system, and connect the three-phase AC and two-phase DC. The closing of the system is the connecting link of the whole system. Two different states treat the circuit system differently, so as to perform switch control according to the working conditions; such a design of switching control according to the working conditions can ensure that the slip ring system will not have power during maintenance, and can ensure the safety...
