Description

Technical Field

[0001] This invention relates to the field of equipment temperature monitoring technology, and specifically to an intelligent temperature monitoring system for operating equipment under high voltage and strong magnetic fields. Background Technology

[0002] In today's power systems, switchgear in 10kV and above distribution rooms is crucial equipment for ensuring stable power transmission and distribution. However, with increasing service life, these switchgear frequently experience severe overheating at conductor joints during operation. According to statistics, a significant proportion of switchgear in some older distribution rooms, exceeding a certain age, exhibits varying degrees of overheating potential, seriously threatening the safe and stable operation of the power system. Existing handheld infrared thermometry methods have many limitations in this high-voltage environment. On the one hand, due to the complex internal structure of the switchgear, with many obstructed and difficult-to-reach areas, handheld infrared thermometers can only detect a limited and incomplete range of potential heat points, making it difficult to effectively identify specific faults. On the other hand, infrared thermometry is easily affected by environmental factors in the factory, such as high-voltage environments, dust, and moisture, making handheld infrared thermometers inaccurate and only offering high flexibility.

[0003] While existing temperature monitoring devices integrated into some switchgear attempt to address the temperature monitoring problem to some extent, they still exhibit serious shortcomings under high voltage and strong magnetic field conditions. Most of these devices cannot operate stably and continuously in such harsh environments, resulting in a generally short lifespan after installation. In practical high-voltage applications, their average lifespan is only about one-third of that under normal conditions. During operation, they are highly susceptible to strong electromagnetic interference, leading to excessive localized temperature rise and overheating, ultimately causing the devices to burn out and become unusable. This not only increases equipment maintenance costs but also seriously affects the safe operation of electrical equipment, potentially leading to large-scale power outages and causing significant losses to production. Summary of the Invention

Figure 2 This is a schematic diagram of the structure of an intelligent temperature monitoring system for operating equipment under high voltage and strong magnetic field conditions, as described in Embodiment 2. Figure 3 This is a schematic diagram of the structure of an intelligent temperature monitoring system for operating equipment under high voltage and strong magnetic field, according to at least one embodiment. Detailed Implementation

[0026] The reference numerals in the accompanying drawings include: A temperature intelligent monitoring system 100 for operating equipment under high voltage and strong magnetic field, comprising a processor 101, a memory 104, and a computer program 1041.

[0027] Example 1 This embodiment provides an intelligent temperature monitoring system for operating equipment under high voltage and strong magnetic field conditions, including a monitoring layout module, a first wiring module, and an alarm module.

[0028] Specifically, the monitoring deployment module uses fiber optic temperature sensors installed at the first critical temperature measurement location of the operating equipment used in industrial production to monitor the real-time temperature of the equipment. The first critical temperature measurement location includes the moving contact arm of the operating equipment. The fiber optic cable length between the fiber optic sensor probe and the zero-potential side of the operating equipment is no less than 1500mm.

[0029] The first wiring module houses the fiber optic temperature sensor within the electrical cabinet of the operating equipment for monitoring the real-time temperature of the cabinet. Within this module, the electrical cabinet includes an instrument compartment, a handcart, a current transformer, and stationary contacts. The fiber optic temperature sensor comprises an optical cable, a fiber optic temperature transmitter, and a fiber optic sensing probe; one end of the fiber optic temperature transmitter is connected to the optical cable, and the other end is connected to the fiber optic sensing probe. The fiber optic temperature transmitter is fixedly mounted in the instrument compartment, and the fiber optic sensing probes are respectively positioned on the stationary contacts, the current transformer, and the power arm of the handcart. The electrical cabinet also includes a circuit breaker handcart and a cable compartment; the optical cable runs from the fiber optic temperature transformer along the corner of the instrument compartment and the low-voltage cable tray, passing sequentially through the circuit breaker handcart compartment and the handcart before entering the cable compartment. The electrical cabinet also includes surge arresters, cables, and a busbar compartment. The optical cable passes sequentially through the surge arresters and cables, enters the cable compartment, and then passes through the cable compartment into the busbar compartment. The first cabling module also includes cable ties, which are used to secure the fiber optic sensing probe to the current transformer and the stationary contact, respectively. The first cabling module also includes multiple mounting brackets, which are used to connect the fiber optic cables, and the cables are laid in a horizontal and vertical manner.

[0030] The alarm module acquires the real-time temperature of the operating equipment and electrical cabinet. If the real-time temperature exceeds a preset temperature threshold, an alarm is triggered. Specifically, if either the operating equipment or the electrical cabinet's real-time temperature exceeds the preset temperature threshold, an alarm is triggered. Alarm methods include audible and visual alarms and SMS alarms.

[0031] The system setup steps in this embodiment First, secure the transmitter. Select suitable mounting hardware, including screws and clips. Secure the transmitter to the rear wall of the switchgear instrument panel. During the securing process, ensure the transmitter is firmly installed to prevent displacement due to equipment vibration or other external forces. Also, pay attention to the selection of the installation location, ensuring it facilitates subsequent maintenance and repair. For example, using high-strength screws to tightly secure the transmitter to the designated position on the rear wall of the switchgear instrument panel, the transmitter remained stable without any loosening after long-term equipment operation.

[0032] Second, the arrangement of fluorescent fiber optic pigtails. Fluorescent fiber optic pigtails should be routed along the corners of the cabinet and in the low-voltage cable trays, or bundled together with the secondary wiring inside the cabinet. Care must be taken during routing to avoid subjecting the pigtails to external pressure, stretching, or twisting, which could affect signal transmission quality. The length of the fiber optic pigtail from the high-voltage side where the sensor head is installed to the zero-potential side must not be less than 15cm; this is a critical requirement for ensuring insulation safety. For example, in an installation practice in a power distribution room, staff strictly followed regulations, accurately measuring the length of the fiber optic pigtails to ensure they met the insulation safety distance requirements, effectively preventing electrical accidents that could have been caused by excessively short fiber optic pigtails.

[0033] Third, the installation of the contact monitoring subsystem. The contact monitoring subsystem can be installed on the moving contact arm of the train or at the connection point between the stationary contact and the busbar. These locations are critical parts of factory equipment in industrial production that are prone to heat generation during operation. Choosing a suitable installation location is crucial for accurate contact temperature monitoring. During installation, it is essential to ensure that the contact monitoring subsystem is in close contact with the contact to guarantee the accuracy of temperature measurements. For example, in the installation of electrical equipment, workers precisely install the contact monitoring subsystem at the connection point between the stationary contact and the busbar. Through long-term comparison of monitoring data, it has been found that temperature changes at this location can promptly reflect the operating status of the equipment, providing important information for the safe operation of the equipment.

[0034] Fourth, probe fixation. Cable ties are used to fix the probe, a method that is simple, reliable, and cost-effective. When fixing the probe, it is important to ensure the cable ties are tightened appropriately; too loose, and the probe may shift, affecting the accuracy of temperature measurements; too tight, and the probe or fiber optic cable may be damaged. Simultaneously, ensure the probe is installed in the correct orientation so it can accurately sense temperature changes in the equipment. In practice, using standard-sized cable ties and fixing the probe with the specified tightness, multiple temperature measurements and equipment operation tests have proven that this fixing method effectively ensures stable probe operation and provides accurate temperature data.

[0035] Fifth, fiber optic cable laying. Fiber optic cables are installed using adhesive mounting brackets, allowing direct mounting to the inner wall of the switchgear. Nylon cable ties are used to secure the sensor fibers, ensuring the fiber optic cable path is horizontal and vertical. This installation method results in a neat and aesthetically pleasing fiber optic layout, facilitating management and maintenance, while reducing mutual interference between fibers and ensuring stable signal transmission. During the fiber optic cable laying process in a certain switchgear, workers used reliable adhesive mounting brackets and nylon cable ties, strictly adhering to the horizontal and vertical requirements for fiber optic cable laying. System testing showed stable fiber optic signal transmission without any interference.

[0036] Sixth, establish a communication connection with the remote monitoring platform. Configure the connection with the remote monitoring platform in the software. Set the RS485 communication parameters, including baud rate, data bits, stop bits, and parity bits, to ensure normal communication between the software and hardware. After a successful connection, the software can receive temperature data transmitted from the remote monitoring platform in real time and display and process it on the computer interface. Through precise setting of communication parameters and multiple communication tests, a stable connection and efficient data transmission between the software and hardware are guaranteed.

[0037] The usage principle of this embodiment Based on the principle of fiber optic temperature measurement, the electromagnetic immunity of optical fibers is key to their stable operation in high-voltage and strong electromagnetic interference environments. Unlike existing electrically connected temperature measurement devices, the temperature hotspot and the signal receiving part of the fluorescent fiber optic temperature sensor do not use an electrical connection. In high-voltage and strong magnetic field environments, the electrical connections of existing temperature measurement devices are easily affected by electromagnetic interference, leading to unstable signal transmission and reduced data accuracy. However, because optical fibers are non-conductive, they are not affected by strong electromagnetic interference, ensuring high accuracy and stability in temperature measurement. In comparative tests under strong electromagnetic interference environments, the measurement data fluctuation range of existing temperature measurement devices reached ±5℃, while the fluctuation range of the fiber optic temperature measurement data in this embodiment was only ±0.5℃. This fully demonstrates the unique advantages of optical fibers in high-voltage and strong electromagnetic interference environments, greatly improving data accuracy and stability, and providing reliable temperature data support for the safe operation of equipment.

[0038] Beneficial effects of this embodiment Firstly, the detailed system setup allows for accurate temperature monitoring while saving on fiber optic cables and reducing costs. It provides a complete set of steps, from transmitter mounting, fluorescent fiber optic pigtail placement, contact monitoring subsystem installation, probe mounting, fiber optic laying, to establishing a communication connection with the remote monitoring platform. These steps clearly guide the installation and deployment of the temperature monitoring system in a real industrial environment, ensuring system reliability and stability. Through specific mounting methods (such as using high-strength screws and clips), fiber optic pigtail placement requirements (such as a minimum length of 15cm to ensure insulation safety), probe mounting methods (such as using cable ties), and fiber optic laying specifications (such as horizontal and vertical alignment), Example 1 provides clear guidance for operators, reducing installation difficulty and error rates.

[0039] Secondly, the accuracy and stability of temperature monitoring. First, the layout of the fiber optic temperature sensor. By placing fiber optic sensor probes in key areas of the electrical cabinet (such as stationary contacts, current transformers, and the power arm of the handcart), the system can comprehensively cover key temperature measurement points within the cabinet, ensuring comprehensive and accurate temperature monitoring. This layout can promptly detect potential overheating issues, preventing equipment failures caused by localized overheating. Second, the electromagnetic immunity of fiber optics. Based on the electromagnetic immunity of fiber optics, the fiber optic temperature sensor can operate stably in high-voltage, strong magnetic environments. Compared to traditional electrically connected temperature measurement devices, fiber optic temperature sensors are unaffected by strong electromagnetic interference, ensuring high accuracy and stability in temperature measurement. In comparative tests, the fluctuation range of fiber optic temperature measurement data was only ±0.5℃, while the fluctuation range of traditional temperature measurement devices could reach ±5℃, fully demonstrating the advantages of fiber optic temperature measurement.

[0040] Finally, regarding the system's reliability and safety: First, the fiber optic cable length is designed to be at least 1500mm between the fiber optic sensing probe and the zero-potential side of the operating equipment. This design ensures the insulation safety of the fiber optic cable under high-voltage conditions, preventing electrical accidents caused by excessively short cables, thus guaranteeing the safe operation of the system. Second, the fixing method uses cable ties to secure the fiber optic sensing probe. This method is simple, reliable, and cost-effective. It effectively prevents the probe from loosening or being damaged during equipment operation, ensuring the accuracy of temperature measurements. It also facilitates installation and maintenance, reducing system maintenance costs and operational complexity.

[0041] Example 2 Unlike the aforementioned embodiments, an intelligent temperature monitoring system for operating equipment under high voltage and strong magnetic fields includes a monitoring equipment connection module and a data transmission and management module, such as... Figure 2As shown, the monitoring equipment connection module includes a fluorescent fiber optic temperature sensor, an alarm device, and a remote monitoring platform. The fiber optic temperature sensor is deployed on the operating equipment used in industrial production to monitor the real-time temperature of the equipment. The fiber optic temperature sensor establishes a communication connection with the fluorescent fiber optic temperature sensor, which in turn establishes communication connections with the alarm device and the remote monitoring platform. A data transmission and management module is used to transmit data between the fluorescent fiber optic temperature sensor and the remote monitoring platform via RS485 communication. RS485 communication has advantages such as long transmission distance and strong anti-interference capability, making it very suitable for data transmission in high-voltage environments. All data acquisition, management, and temperature display are handled by the communication software. The remote monitoring platform integrates multi-channel fluorescent fiber optics to acquire the equipment's temperature data in real time and transmits the data to the background fluorescent fiber optic temperature sensor via an RS485 bus. After receiving the temperature data, the background fluorescent fiber optic temperature sensor first verifies and preprocesses the data to remove potential noise and errors. Then, it stores the processed data in a database for subsequent querying and analysis. Simultaneously, temperature data is displayed in real-time on the monitoring software interface, allowing operators to intuitively understand the equipment's temperature changes. Furthermore, the data transmission and management module also features data backup and recovery functions to ensure data security and integrity, preventing data loss from impacting equipment monitoring and analysis. In this embodiment, the fluorescent fiber optic temperature measurement host and the remote monitoring platform communicate using a first communication protocol, which includes RS485 communication and Modbus-RTU protocol.

[0042] Example 3 Unlike the aforementioned embodiments, an intelligent temperature monitoring system for equipment operating under high voltage and strong magnetic fields includes an alarm module. This alarm module is used to issue an alarm when the temperature exceeds a set threshold, alerting the operator to take timely action. The threshold is set using conventional technical means, but a flexible alarm threshold is configured in the remote monitoring platform. Operators can customize the upper and lower limits of the alarm temperature according to the actual operating conditions and safety requirements of the equipment. Once the temperature data detected by the fluorescent fiber optic monitoring terminal exceeds the set threshold, the monitoring software immediately triggers the alarm mechanism. Alarm methods include audible and visual alarms and SMS alarms, ensuring that operators receive alarm information promptly. The audible and visual alarms use loud sounds and flashing lights from the alarm equipment in the monitoring center to attract the operator's attention; SMS alarms send alarm information to the operator's mobile phone, allowing them to be aware of equipment anomalies even when they are not in the monitoring center. Timely alarm notifications effectively prevent potential accidents, enable tracing the root cause of accidents, reduce unnecessary consumption of manpower and resources, and ensure the safe and stable operation of the equipment.
