Description

Technical Field

[0001] The invention relates to the technical field of heat tracing control of electric power equipment, and in particular to an automatic heating start / stop device and method for outdoor actuators of thermal power plants in high-cold areas. Background Art

[0002] In modern thermal power plants, the normal operation of outdoor actuators directly affects the stability and reliability of the overall equipment, especially in high-cold areas, where low temperatures have an increasingly significant impact on the operation of outdoor actuators. Traditional means of cold protection for outdoor equipment mostly rely on constant heating systems to maintain the operability of the equipment at low temperatures. However, these methods usually output fixed power and lack flexible response to actual temperature changes, resulting in low operating efficiency and high energy consumption of heating cables, making it difficult to meet the dual needs of energy saving and precise control in high-cold environments. With the development of automation and intelligent control technology, some heating devices based on temperature sensor feedback have gradually emerged in the market. These devices can start and stop according to changes in ambient temperature to adapt to different temperature conditions. However, this type of technology still has bottlenecks such as insufficient intelligence, poor temperature response speed, and limited operating data analysis and optimization capabilities. It is difficult to achieve accurate temperature control and efficient heating control in the complex application environment of thermal power plants in high-cold areas.

[0003] Most existing heating control devices lack data recording and analysis functions, and cannot adjust the heating strategy in real time to adapt to the dynamic environment. In addition, traditional equipment generally lacks fault detection and alarm mechanisms, the system reliability is low, and it is difficult to achieve rapid response and automatic protection in the case of a sudden drop in temperature. In contrast, the present invention provides an automatic heating start-up and stop device for outdoor actuators of thermal power plants in high-cold areas, which is equipped with a temperature monitoring alarm module, a processing module, a control module and a heating module. Through the combination of a temperature patrol meter and an alarm system, the present invention can not only intelligently control the opening and closing of the heating cable according to actual temperature changes, but also record and analyze the temperature and heating status during operation, providing data support for future optimization of heating strategies. At the same time, the system of the present invention can automatically calibrate when the heating time exceeds a preset threshold, effectively avoiding energy waste and improving the durability and stability of the equipment. The design of this device comprehensively improves the deficiencies of the existing technology in terms of intelligence, energy saving and safety, and provides innovative technical support for the stable operation of thermal power plants in high-cold environments. Summary of the invention

[0015] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for automatically switching on and off the outdoor actuator of a thermal power plant in a high-cold area, comprising:

[0018] When the outdoor actuator temperature ΔW is lower than the temperature value W2, the alarm sends the low temperature information to the control center.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0034] Example 1, reference Figure 1 , which is an embodiment of the present invention, provides an automatic heating start-stop device for outdoor actuators of thermal power plants in high-cold areas, characterized in that:

[0035] Monitoring and alarm module 100 , processing module 200 , control module 300 and heating module 400 .

[0036] The monitoring and alarm module 100 is provided with a temperature sensor patrol instrument.

[0037] The processing module 200 is connected to the temperature sensor inspection instrument and is used to process the monitored temperature data and set a preset value.

[0038] The control module 300 is connected to the processing module and is used to select whether to turn the heating cable on or off.

[0039] The heating module 400 is used to heat and keep the outdoor actuator warm.

[0040] An alarm is set in the monitoring alarm module to choose whether to issue an alarm message.

[0041] The temperature sensor patrol meter is used to monitor the temperature changes of the required outdoor actuators.

[0042] Example 2, reference Figure 2 , which is an embodiment of the present invention, provides a method for automatically switching on and off the outdoor actuator heating device of a thermal power plant in a high-cold area, characterized in that:

[0043] S1: Collect the outdoor actuator temperature through the temperature sensor patrol meter.

[0044] S2: Based on the temperature of the outdoor actuator, the control module selects the opening and closing of the heating cable.

[0045] The control module selects the opening and closing of the heating cable, including when the outdoor actuator temperature ΔW is lower than the temperature value W1, the control module controls the heating cable to start heating.

[0046] When the outdoor actuator temperature ΔW is lower than the temperature value W2, the alarm sends the low temperature information to the control center.

[0047] When the outdoor actuator temperature ΔW is higher than the temperature value W3, the control module controls the heating cable to turn off heating.

[0048] Among them, W1<W2<W3.

[0049] The control module selects the opening and closing of the heating cable and also includes recording each temperature change and the working status of the heating cable during the start-up and shutdown of the heating device to form historical operation data and optimize the heating strategy through data analysis.

[0050] S3: Select the working condition of the heating cable according to the difference between the temperature of the outdoor actuator and the preset value.

[0051] The preset value is denoted as W0.

[0052] Selecting the working condition of the heating cable includes, when ΔW-W0≤W1, ​​selecting the first preset working condition matrix A1 as the working condition of the heating cable.

[0053] When W1<ΔW-W0≤W2, the second preset working condition matrix A2 is selected as the working condition of the heating cable.

[0054] When W2<ΔW-W0≤W3, the third preset working condition matrix A3 is selected as the working condition of the heating cable.

[0055] Selecting the working conditions of the heating cable also includes setting the automatic start and stop calibration function to automatically detect and calibrate the preset temperature value and working condition matrix when the operation time of the heating cable exceeds the working time threshold.

[0056] By introducing the concept of preset working condition matrix, the appropriate heating cable working condition is automatically selected according to the difference between the temperature and the preset value. Different temperature differences will activate different matrices, allowing the heating cable to work under the first, second or third conditions, thereby maintaining the equipment temperature with optimal power output under low temperature conditions. In addition, S3 also includes an automatic start and stop calibration function. When the operating time of the heating cable exceeds the set working time threshold, the system automatically detects and calibrates the preset temperature value and working condition matrix to ensure the continuous stability of the system in long-term operation. This step can effectively avoid the energy waste and equipment loss caused by the long-term operation of the heating cable, and further improve the reliability and energy efficiency management level of the system.
