Description

[0002] There are many types of excitation signal faults in large synchronous motor drive components, and they cover a wide range of technical aspects. When a fault occurs during normal production, it takes a very long time to find the fault, and most of the time the exact fault cannot be found, which poses a great threat to the continuity and stability of production.
[0003] The various sub-control systems in the prior art do not identify, collect, and convert key signals. In this way, when a general signal fault is reported, there is no directional direction and it can only be searched blindly. Targeted and rapid processing cannot be achieved. In the process of searching, there may even be problems such as damage to the circuit and related components. Furthermore, directional errors may lead to misjudgment of related causes and further delay processing, ultimately resulting in extended fault processing time and reduced production operation rate.

[0029] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.
[0030] Example 1
[0031] according to Figure 1 As shown, this embodiment proposes a detection and processing system for synchronous motor transmission component excitation signal faults, including a power stator detection and conversion system, an air-water and DC component system, a main power AC / DC system, a communication integrated coding system, and a transmission and visualization processing system:
[0032] The power stator detection and conversion system is used to detect the operating status of the power cabinet cooling component power supply system and convert it into a digital switch signal. It then detects the operating status of the motor system stator winding insulation heating power supply system and the motor system stator winding insulation heating power supply system and converts it into a digital switch signal.
[0033] The power cabinet cooling assembly consists of the upward exhaust fan and power supply control system of the rectifier cabinet of system one, the upward exhaust fan and power supply control system of the inverter cabinet of system one, the upward exhaust fan and power supply control system of the DC reactor link cabinet, the upward exhaust fan and power supply control system of the rectifier cabinet of system two, and the upward exhaust fan and power supply control system of the rectifier cabinet of system two. The power cabinet cooling assembly can quickly dissipate heat of the power unit and thus ensure the safe and stable operation of the entire transmission system; the stator winding of the motor system one and the stator winding of the motor system two together constitute the stator winding of the synchronous motor, and the two windings correspond to two transmission control systems and two power supply systems. The insulation heating treatment system refers to the heating assembly embedded in the motor winding and the supporting power supply system. The insulation heating treatment system can ensure the insulation of the motor whether it is during the steel rolling process or during maintenance, whether it is dry weather or humid environment, the insulation of the motor winding can be ensured to be normal;
[0034] The air-water and DC component system is used to detect the operating status of the synchronous motor's air-water cooler power supply system near the heating furnace and the synchronous motor's air-water cooler power supply system near the No. 1 water tank, and convert them into digital switch signals. It then detects the operating status of the DC speed regulator's cooling component power supply system and the DC speed regulator's drive and conversion component power supply system, and converts them into digital switch signals.
[0035] The air-water cooler for synchronous motors is an integrated cooling system combining air and water cooling. Installed directly below the synchronous motor, it is supported and secured by an intermediate transition plate and intermediate support columns. Through closed air circulation and water cooling, the motor windings can be efficiently cooled, thereby increasing their service life and reliability.

The DC speed control device, used to regulate and control the voltage of the excitation system, consists of a dry-type transformer system, a low-voltage power supply component, a knife switch control system, a large contactor control component, an auxiliary signal acquisition and transmission system, a key voltage regulation system, and a voltage output and detection system. Both the DC speed control device and its cooling system require electrical power.
[0036] The main power AC / DC system is used to detect the operating status of the main power cabinet input component power system and convert it into a digital switch signal. It then detects the action signal of the DC link overvoltage and overcurrent detection system and the AC link overvoltage and overcurrent detection system and converts them into digital switch signals.

The main power cabinet input component power supply system can provide power for the entire excitation system. The DC link overvoltage and overcurrent detection system can detect, identify, and absorb overvoltage and overcurrent in the DC link of the entire excitation system, thereby preventing DC link overloads on the entire system's components. The AC link overvoltage and overcurrent detection system can detect, identify, and absorb overvoltage and overcurrent in the AC link of the entire excitation system, thereby preventing AC link overloads on the entire system's components.
[0038] The communication integrated coding system is used to diagnose communication components and quantify and identify abnormal signals before converting them into visual signal outputs. The abnormal signals are then integrated and coded and grouped in the central integrated control and processing center.
[0039] The communication component consists of a communication transmission system, a communication diagnosis system, a communication identification system, a communication quantization grouping and a compilation system. By diagnosing and identifying abnormal signals, and transmitting and judging them in a timely manner, it is possible to quickly diagnose and process abnormal communications. The central integrated control and processing center is the control center of the entire transmission system, and can quickly and efficiently control various signals and instructions. Integrating the coding and signal grouping of abnormal signals can achieve rapid identification of abnormal signals in the event of an abnormal fault, as well as accurate positioning of the fault location and faulty components.
[0040] The transmission and visual processing system achieves signal transmission between the excitation component end and the central control end through bilateral and symmetrical communication. Then, the central control end can quickly query and visually process faults through visual fault display.
[0041] Bilateral communication and symmetrical communication refer to the output communication and input communication between the entire excitation control system and the central integrated control and processing center. Through such communication transmission, fault information and abnormal information can be quickly transmitted; visual fault display can visualize and locate abnormal signals and abnormal information of the excitation system, thereby enabling fast and accurate processing. Such innovative design and innovative application can realize visual and rapid processing of abnormal excitation signals and excitation faults.

The power stator detection and conversion system consists of a power actual value detection component, a power unit input and output component, a stator winding temperature measurement system, a stator winding hot air detection system, a stator winding cold air detection system, a voltage quantization detection system, and a current quantization detection system. Converting the power system operating status into a digital switch signal enables convenient transmission and visualization of key status signals.
[0045] The air-water and DC component system is used to detect the operating status of the synchronous motor's supporting air-water cooler's motor power supply system, located near the heating furnace and the No. 1 water tank, and to detect the operating status of the DC speed control device's cooling components, drive, and conversion components.

The symmetrical wind turbine motor design of the air-water cooling system maximizes air volume and cooling efficiency.
[0046] The main power AC / DC system is used to detect the operating status of the main power cabinet input component power system, and detect overvoltage and overcurrent detection system action signals in the DC and AC links.

By controlling the key links of the main power AC / DC system and dynamically handling abnormal situations, the anti-interference performance of the excitation system can be improved.
[0047] The communication integrated coding system is used to diagnose communication components, quantify and identify abnormal signals, and convert them into visual signal outputs. It also integrates and encodes abnormal signals and groups them in a central integrated control and processing center. The communication integrated coding system consists of a communication transmission and feedback system, a communication diagnosis and recording system, a communication abnormality visual display system, a communication signal and status integration system, and a communication signal and status compilation system.
