Description

Technical Field

[0001] The invention relates to the technical field of pressure gauges, in particular to an intelligent movement of a sulfur hexafluoride gas pressure gauge. Background Art

[0002] In the power system, SF6 (sulfur hexafluoride) gas is widely used in electrical equipment such as high-voltage circuit breakers, power transformers, combination electrical appliances, switch cabinets, etc. due to its excellent insulation and arc extinguishing performance. These devices are usually filled with SF6 gas of a certain pressure value to ensure their normal operation and insulation performance. The stability of SF6 gas pressure is crucial to the safe operation of electrical equipment. If the SF6 pressure value changes erratically, it may affect the insulation performance of the equipment and even cause equipment failure. For example, when the SF6 pressure drops to a certain value, it may cause problems such as the circuit breaker failing to close normally and the power transformer measuring inaccurately. Therefore, a high-precision and high-reliability SF6 pressure gauge is required to accurately monitor the pressure of SF6 gas.

[0003] When the traditional mechanical Bourdon tube SF6 pressure gauge is used, the pressure value indicated by the dial pointer cannot be transmitted to the power grid management and control platform in real time. Regular manual inspections and records are required. The SF6 gas pressure cannot be monitored in real time, and there are certain safety hazards in the operation of power equipment. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent movement for a sulfur hexafluoride gas pressure gauge to solve the problems existing in the above-mentioned prior art, which can detect in real time and transmit the pressure information to the equipment control system or monitoring terminal to realize real-time monitoring of SF6 gas pressure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide an intelligent movement for a sulfur hexafluoride gas pressure gauge to solve the problems existing in the prior art, and to be able to detect in real time and transmit pressure information to an equipment control system or a monitoring terminal, thereby realizing real-time monitoring of SF6 gas pressure.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 3 As shown, this embodiment provides an intelligent movement of a sulfur hexafluoride gas pressure gauge, including a first fixed plate 1, a second fixed plate 2, a central shaft 3, a large gear 4 and a small gear 5. The first fixed plate 1 is fixedly connected to the second fixed plate 2, and both ends of the central shaft 3 are rotatably connected to the first fixed plate 1 and the second fixed plate 2 respectively. The small gear 5 is fixed to the central shaft 3, and the large gear 4 is rotatably connected to the first fixed plate 1 and the second fixed plate 2 and meshes with the small gear 5. A signal sensor 6 is provided at one end of the central shaft 3 for detecting a rotation angle signal of the central shaft 3. The signal sensor 6 is connected to the monitoring terminal signal. The signal sensor 6 is fixed to a sensor seat 7, and the sensor seat 7 is fixedly mounted on the second fixed plate 2.

[0023] When the SF6 gas pressure gauge movement is working, the central axis 3 will rotate with the operation of the equipment, and the signal sensor 6 will sense the angle change of the central axis 3 in real time, and convert it into an electrical signal and transmit it to the equipment control system or monitoring terminal. The signal processing system in the equipment control system or monitoring terminal can amplify, filter, and perform analog-to-digital conversion on these signals, and convert them into data that can be read and analyzed by the equipment control system or monitoring personnel. By analyzing these data, the operating status of the SF6 gas pressure gauge movement and the relevant parameters of SF6 gas can be understood in real time, potential problems or abnormal conditions can be discovered in time, and corresponding measures can be taken to avoid the occurrence or expansion of faults, thereby improving the reliability and safety of the equipment.

[0024] The shell of the signal sensor 6 has good sealing and electromagnetic shielding performance, which can effectively resist interference from external electromagnetic fields, dust, moisture and other factors. The signal sensor 6 can work stably in complex electromagnetic environments and harsh working conditions. For example, in strong electromagnetic environments such as power substations, the signal sensor 6 can still accurately collect and transmit data without being affected by electromagnetic interference from other electrical equipment. At the same time, the signal sensor 6 can adapt to different environmental conditions such as high temperature, low temperature, and high altitude, and can work normally in the temperature range of -40°C to +85°C and in environments below 5000 meters above sea level, ensuring the reliable operation of the SF6 gas pressure gauge movement in various complex environments.

[0025] The signal sensor 6 has a good communication interface and intelligent functions, is easy to integrate with the existing intelligent monitoring system, and can be connected to the monitoring terminal signal through a wired or wireless transmission method. When a wired transmission method is adopted, a communication interface 9 can be set on the signal sensor 6, and a communication cable can be connected through the communication interface 9.

[0026] The signal sensor 6 can transmit sensor data to the remote monitoring center through Ethernet, wireless communication, etc., to realize remote real-time monitoring and management of the SF6 gas pressure gauge movement. The operator can view the operating status, historical data and alarm information of the equipment at any time on the remote terminal, and perform remote control and parameter adjustment. This makes the management of the equipment more convenient and efficient, and is especially suitable for centralized monitoring and management of widely distributed power equipment, industrial production equipment, etc. For example, in a city's power grid system, the remote monitoring center can monitor the SF6 equipment of each substation in real time, realize intelligent operation and maintenance management, and improve the overall operation efficiency and reliability of the power grid.

[0027] In this embodiment, the signal sensor 6 is a Hall angle sensor. The Hall angle sensor adopts digital signal processing technology, has high precision and high resolution, can accurately measure real-time signals, and ensure the stability and reliability of the measurement. The Hall sensor is a non-contact sensor with a fast response speed, which can detect signal changes in real time, and improve the control accuracy and stability of the system. The Hall sensor has a strong anti-interference ability against external interference and magnetic field influences, and can ensure stable and reliable operation in complex environments. Since the Hall sensor is not as easy to wear and fail as a contact sensor, it has a longer lifespan, which is conducive to reducing maintenance and replacement costs. The Hall sensor is small in size and simple in structure, and can be installed in a small space, which is very suitable for the integrated design of this movement.

[0028] In this embodiment, the sensor seat 7 is fixed to the second fixing plate 2 by screws 8, which is convenient and quick to install and easy to disassemble and repair.

[0029] The present invention can be applied to power equipment such as SF6 circuit breakers and GIS (gas insulated switchgear) to monitor the pressure of SF6 gas and ensure the normal operation of power equipment. It can also be applied to some industrial production equipment that uses SF6 gas as insulation or protective gas, such as semiconductor manufacturing equipment, chemical equipment, etc., to monitor the leakage of SF6 gas, the operating status of the equipment, etc., to ensure the safety and stability of the production process.

[0030] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
