Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, and in particular to a temperature measuring device for air-core reactors. Background Technology

[0002] In power systems, air-core reactors serve as critical equipment for reactive power compensation and filtering, and their operating status directly impacts the stability and reliability of the power grid. Temperature is a crucial parameter reflecting the operational health of air-core reactors; excessively high temperatures can lead to insulation aging, performance degradation, and even serious accidents such as fires. Therefore, developing accurate and reliable temperature measurement devices for air-core reactors is of paramount importance for real-time monitoring of their operating temperature and ensuring the safe and stable operation of the power system.

[0003] Existing temperature measurement technologies for air-core reactors mostly employ traditional thermocouples or thermistors as temperature sensing elements. These elements are installed on the surface or in key internal locations of the reactor to acquire temperature data. After converting the temperature signal into an electrical signal, the data is transmitted to a data acquisition module, and then transmitted to a monitoring terminal for display and analysis via wired or wireless communication. Mechanically, simple mounting brackets are typically used to fix the sensing elements in designated positions on the reactor, lacking comprehensive protection and power supply design.

[0004] However, existing temperature measurement devices suffer from inaccurate and inconsistent temperature monitoring. Traditional thermocouples or thermistors are installed on the surface of the reactor or in limited critical areas, failing to comprehensively capture temperature changes within the reactor's internal air passages. Furthermore, during long-term operation, environmental factors and electromagnetic interference from the reactor itself can cause errors in signal transmission, resulting in inaccurate monitoring data. These devices cannot meet the need for real-time and accurate temperature monitoring of air-core reactors, and therefore cannot provide reliable assurance for the safe and stable operation of reactors. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a temperature measuring device for air-core reactors, aiming to improve the problems of inaccurate temperature monitoring and poor continuity of existing temperature measuring devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature measuring device for a hollow reactor, comprising a reactor body, an air duct inside the reactor body, a fixing frame fixedly connected to the upper and lower surfaces of the reactor body, a terminal block fixedly connected to the end of the fixing frame, a supporting insulator fixedly connected to the bottom of the reactor body, a bracket provided on one side of the reactor body, a fence provided between the reactor body and the bracket, and a temperature measuring component provided inside the reactor body;

[0007] The temperature measuring component includes a temperature measuring optical fiber and a temperature sensor. One end of the temperature measuring optical fiber is disposed inside the gas channel of the reactor body, and the other end of the temperature measuring optical fiber is fixedly connected to the temperature sensor. A display is installed at the bottom of the temperature sensor, and a power supply is fixedly connected to the bottom of the bracket. The display and the power supply are connected by a connecting cable harness.

[0008] Furthermore, a sliding sleeve is fixedly connected to the upper surface of the bracket, and a protective component is provided above the sliding sleeve.

[0009] Furthermore, the protective assembly includes a sliding rod and a protective top plate. The outer wall of the sliding rod is slidably connected inside the sliding sleeve, the protective top plate is fixedly connected to the top of the sliding rod, a spring is sleeved at the bottom of the sliding rod, and a limit plate is fixedly connected to the outer wall of the sliding rod.

[0010] Furthermore, one end of the spring is fixedly connected to the inside of the sliding sleeve, and the other end of the spring is fixedly connected to the lower surface of the limiting plate.

[0011] Furthermore, the outer wall of the limiting plate is slidably connected inside the sliding sleeve to drive one end of the spring to move.

[0012] Furthermore, the protective top plate is disposed above the bracket to protect the bracket.

[0013] Furthermore, the temperature sensor is located at the top of the bracket, and the power supply is located at the bottom of the bracket.

[0014] Furthermore, the display is positioned at the front end of the bracket.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by arranging temperature-measuring optical fibers in the air duct of the reactor body, the temperature changes of the air duct can be captured in real time. The data is converted by temperature sensors and presented intuitively on the display. Combined with the stable power supply at the bottom, a complete and efficient temperature monitoring system is formed, which ensures accurate and continuous monitoring of the temperature of the hollow reactor, provides reliable data support for the safe and stable operation of the reactor, and effectively avoids equipment failure caused by abnormal temperature.

[0017] 2.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figs. 1-3 An embodiment of this utility model provides a temperature measuring device for a hollow reactor, comprising a reactor body 1, an air duct 2 inside the reactor body 1, a fixing frame 3 fixedly connected to the upper and lower surfaces of the reactor body 1, a terminal block 4 fixedly connected to the end of the fixing frame 3, a supporting insulator 5 fixedly connected to the bottom of the reactor body 1, a bracket 8 provided on one side of the reactor body 1, a fence 6 provided between the reactor body 1 and the bracket 8, and a temperature measuring component provided inside the reactor body 1.

[0025] The temperature measuring component includes a temperature measuring fiber 7 and a temperature sensor 11. One end of the temperature measuring fiber 7 is located inside the gas duct 2 of the reactor body, and the other end of the temperature measuring fiber 7 is fixedly connected to the temperature sensor 11. A display 17 is installed at the bottom of the temperature sensor 11. A power supply 9 is fixedly connected to the bottom of the bracket 8. The display 17 and the power supply 9 are connected by a connecting wire harness 10. The temperature sensor 11 is located at the top of the bracket 8, the power supply 9 is located at the bottom of the bracket 8, and the display 17 is located at the front end of the bracket 8.

[0026] Specifically, during use, a temperature-sensing optical fiber 7 is arranged in the reactor body air duct 2 inside the reactor body 1 to monitor the air duct temperature changes in real time. The temperature-sensing optical fiber 7 transmits the temperature signal to the temperature sensor 11 at the top of the bracket 8. After conversion, the temperature data is displayed visually on the display 17 at the front of the bracket 8. The power supply 9 at the bottom of the bracket 8 supplies power to the display 17 and the temperature sensor 11 through the connecting cable harness 10, ensuring continuous and stable temperature monitoring. At the same time, the fence 6 provides isolation and protection, ensuring that the device can safely and reliably complete the temperature acquisition and display functions during reactor operation, and avoiding interference from external factors in the monitoring process.

[0027] Reference Fig. 3 A sliding sleeve 16 is fixedly connected to the upper surface of the bracket 8. A protective assembly is provided above the sliding sleeve 16. The protective assembly includes a sliding rod 13 and a protective top plate 12. The outer wall of the sliding rod 13 is slidably connected to the inside of the sliding sleeve 16. The protective top plate 12 is fixedly connected to the top of the sliding rod 13. A spring 15 is sleeved on the bottom of the sliding rod 13. A limiting plate 14 is fixedly connected to the outer wall of the sliding rod 13. One end of the spring 15 is fixedly connected to the inside of the sliding sleeve 16. The other end of the spring 15 is fixedly connected to the lower surface of the limiting plate 14. The outer wall of the limiting plate 14 is slidably connected to the inside of the sliding sleeve 16 to drive one end of the spring 15 to move. The protective top plate 12 is located above the bracket 8 to protect the bracket 8.

[0028] Specifically, when the protective top plate 12 is subjected to pressure, it causes the sliding rod 13 to slide inside the sliding sleeve 16. The movement of the sliding rod 13 further causes the limiting plate 14 to slide inside the sliding sleeve 16, thereby causing the spring 15 to extend and retract. Through the extension and retraction of the spring 15, the device can effectively buffer external impacts and resist rainwater intrusion, protecting the internal temperature measuring elements and circuits. This design greatly improves the protective performance of the device in complex environments, enhances the reliability and service life of the device, reduces the cost of equipment damage and maintenance caused by external factors, and ensures the long-term stable operation of the temperature measuring device.

[0029] Working principle: When this temperature measuring device is needed, a temperature-measuring optical fiber 7 is first arranged in the reactor body air duct 2 inside the reactor body 1 to monitor the temperature change of the air duct in real time. The temperature-measuring optical fiber 7 transmits the temperature signal to the temperature sensor 11 at the top of the bracket 8. After conversion by the temperature sensor 11, the temperature data is displayed intuitively on the display 17 at the front of the bracket 8. The power supply 9 at the bottom of the bracket 8 supplies power to the display 17 and the sensor 11 through the connecting harness 10, realizing continuous and stable temperature monitoring. The device is isolated and protected by the fence 6 to ensure that it can safely and reliably complete the temperature acquisition and display functions during reactor operation.

[0030] In addition, when the protective top plate 12 is subjected to pressure, the protective top plate 12 will drive the sliding rod 13 to slide inside the sliding sleeve 16. At the same time, the movement of the sliding rod 13 will drive the limiting plate 14 to slide inside the sliding sleeve 16, thereby driving the spring 15 to extend and retract. The spring 15 will then buffer the external force, thus achieving protection against external forces and rainwater.
