Problems solved by technology

[0003] Due to the high-speed rotation of the finishing rolling motor, the relevant components of the rotor slip ring will absorb a large amount of oil gas and water vapor, as well as the mixed oil gas and mixed water vapor mixed with metal dust mixture such as iron oxide scale due to negative pressure, which will cause the rotor slip ring Grounding deterioration leads to extremely dangerous factors in the operation of the finishing rolling motor. If there is no quantitative data p

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...

Abstract

The invention provides a rotor slip ring grounding deterioration early warning system and method, and relates to the technical field of steel production, the system comprises a connection detection system, a closing enabling system, an actual value acquisition middle end, a threshold comparison conversion system and an early warning processing output system, the connection detection system is used for connecting a left phase and a middle phase of a three-phase alternating 170V power supply; according to the invention, rotor slip ring grounding quantitative data can be dynamically collected and dynamically monitored, and early warning of rotor slip ring grounding deterioration is realized through signal conversion and signal transmission and logic processing and quantitative output of the central processing unit. The grounding deterioration of the slip ring of the rotor can be found in time, and the searching analysis and locking of accurate grounding points and grounding sources of a video acquisition system, a picture acquisition system and a manual proofreading system are combined, so that the running environment tolerance of the finish rolling motor is greatly improved; and finally, safe and stable operation of the finish rolling motor and maximization of production efficiency and production yield are realized.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a system and method for early warning of grounding degradation of a rotor slip ring. Background technique [0002] The 6000KW synchronous motor for high-end finishing rolling is the core heart equipment of high-line finishing rolling. The safe and stable operation of the 6000KW synchronous motor for high-speed finishing rolling is directly related to the stable and high output of the high-line finishing rolling production line. However, due to the limitations of the overall layout of the rolling line and related equipment such as finish rolling motor, finish rolling speed-up box, finish rolling 10 roll boxes, finish rolling 10 cone boxes and other equipment, the finish rolling motor is installed under the plane of the five-meter platform of the high line, The environment around the entire motor is extremely harsh, with a large amount of oil, gas, water vapor, an...
