Description

Technical Field

[0001] The utility model 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 power systems, SF6 (sulfur hexafluoride) gas is widely used in electrical equipment such as high-voltage circuit breakers, power transformers, switchgear, and other electrical equipment due to its excellent insulation and arc-extinguishing properties. These devices are typically filled with SF6 gas at a certain pressure to ensure proper operation and insulation performance. The stability of SF6 gas pressure is crucial for the safe operation of electrical equipment. Unpredictable fluctuations in SF6 pressure can affect the insulation performance of the equipment and even cause equipment failure. For example, when SF6 pressure drops below a certain value, it can cause circuit breakers to fail to close properly and power transformers to make inaccurate measurements. Therefore, high-precision, high-reliability SF6 pressure gauges are required to accurately monitor SF6 gas pressure.

[0003] When traditional mechanical Bourdon tube SF6 pressure gauges are 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, and the SF6 gas pressure cannot be monitored in real time. There are certain safety hazards in the operation of power equipment.

[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] The purpose of the utility model is to provide an intelligent movement for a sulfur hexafluoride gas pressure gauge to solve the problems existing in the prior art. It can detect in real time and transmit the pressure information to the equipment control system or 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 implementation methods.

[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 operating, central axis 3 rotates with the operation of the device. Signal sensor 6 senses the angular changes of central axis 3 in real time and converts them into electrical signals, which are then transmitted to the device control system or monitoring terminal. The signal processing system in the device control system or monitoring terminal amplifies, filters, and performs analog-to-digital conversion on these signals, converting them into data that can be read and analyzed by the device control system or monitoring personnel. By analyzing this data, the operating status of the SF6 gas pressure gauge movement and relevant SF6 gas parameters can be understood in real time, allowing potential problems or abnormal conditions to be promptly identified and appropriate measures to be taken to prevent the occurrence or escalation of failures, thereby improving the reliability and safety of the equipment.

[0024] The housing of the signal sensor 6 has excellent sealing and electromagnetic shielding properties, and can effectively resist interference from external electromagnetic fields, dust, moisture and other factors. The signal sensor 6 can operate stably in complex electromagnetic environments and harsh working conditions. For example, in a strong electromagnetic environment such as a power substation, 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. It can work normally in a temperature range of -40°C to +85°C and in an environment below 5,000 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, which makes it easy to integrate with existing intelligent monitoring systems and can be connected to the monitoring terminal signal through wired or wireless transmission. When using wired transmission, a communication interface 9 can be provided on the signal sensor 6, and a communication cable can be connected through the communication interface 9.

[0026] Signal sensor 6 transmits sensor data to a remote monitoring center via Ethernet, wireless communications, and other methods, enabling remote, real-time monitoring and management of the SF6 gas pressure gauge movement. Operators can view the device's operating status, historical data, and alarm information at any time on the remote terminal, and perform remote control and parameter adjustments. This makes device management more convenient and efficient, and is particularly suitable for centralized monitoring and management of widely distributed power equipment and industrial production equipment. For example, in a city's power grid system, a remote monitoring center can provide real-time monitoring of SF6 equipment at each substation, enabling intelligent operation and maintenance management and improving the overall efficiency and reliability of the power grid.

[0027] In this embodiment, the signal sensor 6 is a Hall angle sensor. The Hall angle sensor uses digital signal processing technology with 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 and can detect signal changes in real time, thereby improving 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 prone to wear and failure as contact sensors, it has a longer lifespan, which helps reduce maintenance and replacement costs. The Hall sensor is small in size and simple in structure, can be installed in a small space, and is very suitable for the integrated design of this movement.

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

[0029] This utility model can be applied to power equipment such as SF6 circuit breakers and GIS (gas insulated switchgear) to monitor SF6 gas pressure and ensure the normal operation of power equipment. It can also be applied to industrial production equipment that uses SF6 gas as an insulating or protective gas, such as semiconductor manufacturing equipment and chemical equipment, to monitor SF6 gas leakage and equipment operating status, thereby ensuring 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 intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
