Description

Technical Field

It has many advantages such as small footprint, high operational reliability, little impact from the external environment, and less maintenance workload. Therefore, it has been widely used in modern power systems, especially in urban substations, large industrial enterprise substations, and places with high requirements for space and environment.

There are many reasons for gas leakage, such as aging of the sealing parts of the equipment, loose connection parts due to long-term vibration, and the appearance of small gaps caused by frequent operation. As the gas leaks, the gas pressure inside the GIS will gradually decrease, and the stability of the gas pressure is crucial to maintaining the insulation performance and arc extinguishing ability of the GIS equipment. Once the gas pressure is lower than the specified value, it may cause serious consequences such as insulation breakdown and ineffective arc extinguishing, affecting the normal operation of the equipment and even causing power system failure.

DETAILED DESCRIPTION

[0019] The following will be combined with 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] Example:

[0021] like Figure 1 The present embodiment provides a high-efficiency electric-assisted GIS intelligent gas replenishment system, including a data acquisition unit 100, an intelligent gas replenishment unit 200 and a control response unit 300, wherein: the data acquisition unit 100 is used to obtain gas information data of the GIS gas chamber and the gas information data of the gas storage device; the intelligent gas replenishment unit 200 analyzes and obtains the safety and charging and discharging requirements of the gas in the GIS gas chamber and the gas in the gas storage device according to the received information data and in combination with the stored gas detection safety standards, and according to the obtained analysis results, calls the preset processing scheme, intelligently starts the preset scheme, and the intelligent gas replenishment unit 200 is connected to the data acquisition unit 100; the control response unit 300 replenishes and replaces the gas in the GIS gas chamber and the gas storage device according to the received instructions, and is used for management personnel to view the intelligent analysis results and upload and update pre-stored information, and the control response unit 300 is connected to the intelligent gas replenishment unit 200.

[0022] Among them, the gas information data includes gas density data, gas pressure data and gas humidity data.

[0023] In the present embodiment, it should be noted that the data acquisition unit 100 can be used to obtain data information of the gas in the GIS air chamber and the gas in the gas storage device in real time, that is, density data, pressure data and humidity data are obtained respectively. As an implementation method, the acquisition method includes but is not limited to density sensors, pressure sensors and humidity sensors, etc. The acquired data information is remotely transmitted to the intelligent gas replenishment unit 200. After the intelligent gas replenishment unit 200 receives the data information, it will classify the data information according to the type of data information. As an implementation method, it includes classifying the gas density data, pressure data and humidity data in the GIS air chamber within the corresponding period, and the gas density data, pressure data and humidity data in the gas storage device, and then retrieving the pre-stored detection standards from the database, comparing each data with the corresponding safety standards, and then obtaining multiple groups of comparison results, and determining whether it is necessary to adjust the processing plan according to the comparison results. As an implementation method of the present embodiment, if the gas density data, pressure data and humidity data in the GIS air chamber within the corresponding period If any comparison result of the humidity data exceeds the detection standard, it is necessary to mobilize the processing plan. For example, when the pressure is too low, the corresponding processing plan will be activated, the air replenishment valve will be opened, and the GIS air chamber will be replenished with gas by electric assistance. At the same time, the data information of the gas in the GIS air chamber will be obtained in real time, and the analysis will be repeated until the detection standard is met. For example, when the humidity data does not meet the detection standard, the exhaust valve of the GIS air chamber will be opened to discharge the gas in the GIS air chamber. As a method of this implementation, a gas collection device can also be provided to collect the exhausted gas, and then replenish the gas that meets the detection standard, and repeat the analysis until the detection standard is met. The present invention can realize the intelligent replenishment and updating of the gas in the GIS air chamber and the gas storage equipment, thereby improving safety. At the same time, remote intelligent control is adopted, and manual processing is not required, thereby improving the processing effect. In addition, the management personnel can preset the processing plan and detection standard in advance, and use electric assisted air replenishment to achieve the manually set intelligent and efficient electric-assisted GIS intelligent air replenishment effect.

[0024] like Figure 2, which is the specific structure of the data acquisition unit 100. The unit consists of a first detection module 110, a second detection module 120 and a first communication module 130. In actual applications, the first detection module 110 is deployed in the GIS air chamber and is responsible for monitoring key parameters such as gas density, pressure and humidity. At the same time, the second detection module 120 monitors the gas state in the gas storage device. Once any abnormality is detected, the two detection modules immediately transmit the data to the first communication module 130, and the communication module is responsible for sending the data to the intelligent gas replenishment unit to provide data support for subsequent intelligent analysis and gas replenishment decisions. Its highly integrated and modular design improves the accuracy and real-time performance of data acquisition, facilitates subsequent maintenance and upgrades, and enables the data acquisition unit to efficiently transmit data to the intelligent gas replenishment unit, providing a solid foundation for subsequent intelligent analysis.

[0025] In this embodiment, it should be noted that the first detection module 110 is used to detect data information of gas in the GIS air chamber. As an implementation method, the first detection module 110 includes but is not limited to a density sensor, a pressure sensor, a humidity sensor, etc. At the same time, the collected data information will be labeled and the collected data will be uploaded to the intelligent gas replenishment unit 200 through the first communication module 130. In addition, the second detection module 120 can also upload the detection data of the gas in the gas storage equipment to the intelligent gas replenishment unit 200 using the first communication module 130 for subsequent intelligent analysis.

[0026] like Figure 3 , which is the specific structural structure of the intelligent gas replenishment unit 200. The unit includes a second communication module 210, a data analysis module 220, an intelligent control module 230 and a database module 240. After receiving the data transmitted by the data acquisition unit, the data analysis module 220 first retrieves the pre-stored detection standard from the database module 240, and then compares and analyzes the received data with the standard threshold. Once it is found that the gas state of the GIS gas chamber or gas storage equipment does not meet the safety standard, the intelligent control module 230 is immediately started and generates gas replenishment instructions according to the preset processing scheme. These instructions are then sent to the control response unit through the second communication module 210 to guide the execution of the gas replenishment operation. The innovation lies in its intelligent decision-making mechanism, which can automatically determine whether gas replenishment is needed based on the analysis results and retrieve the preset processing scheme. This decision-making method is more accurate and efficient than traditional manual judgment, effectively avoids the occurrence of human errors, and further improves the safety and reliability of the system.

[0027] The process of comparing the received data information with the corresponding standard threshold to obtain the corresponding safety information and the inflation and deflation requirements is as follows: According to the type of the acquired data information, the acquired data information is classified; according to the acquired classified data information, the corresponding pre-stored test standard information is retrieved from the database; the classified data information is respectively compared with the corresponding test standard information to determine the safety and inflation and deflation requirements.

[0028] In the present embodiment, it should be noted that the data information of the data acquisition unit 100 is received by the second communication module 210, and is uploaded to the data analysis module 220. After receiving the data information, the data analysis module 220 first classifies the acquired data information, and then retrieves the corresponding pre-stored detection standard information from the database according to the obtained classified data information, and finally compares the classified data information with the corresponding detection standard information, so as to obtain the analysis result. As an implementation method of the present embodiment, if any comparison result of the gas density data, pressure data and humidity data in the GIS air chamber within the corresponding period exceeds the detection standard, the result is the corresponding mobilization processing scheme. If the pressure is too low, the corresponding processing scheme will be subsequently started, the air replenishment valve will be opened, and the gas will be replenished into the GIS air chamber by electric assistance.

[0029] In the present invention, the intelligent gas replenishment unit 200 also includes an intelligent control module 230 and a database module 240, wherein: the intelligent control module 230 intelligently starts the preset plan based on the obtained analysis results and the retrieved preset processing plan, and the intelligent control module 230 is connected to the second communication module 210 and the data analysis module 220; the database module 240 is used to store the processing plans and detection standards uploaded by the management personnel, and the database module 240 is connected to the second communication module 210, the data analysis module 220 and the intelligent control module 230.

[0030] In this embodiment, it should be noted that after the intelligent control module 230 receives the analysis results, it will retrieve the corresponding processing plan from the database module 240 according to the corresponding analysis results, identify the content of the processing plan, and send the corresponding instructions to the control response unit 300 through the second communication module 210. In addition, the management personnel can also use the control response unit 300 to upload pre-stored information, including processing plans, etc., which will be received by the second communication module 210 and stored in the database module 240.

[0031] like Figure 4The structure of the control response unit 300. The unit consists of a third communication module 310, a valve opening and closing module 320, an electric air supply module 330 and a display input module 340. After receiving the air supply instruction sent by the intelligent air supply unit, the third communication module 310 immediately transmits the instruction to the valve opening and closing module 320 and the electric air supply module 330. The valve opening and closing module controls the opening of the air supply valve according to the instruction, while the electric air supply module is responsible for replenishing gas into the GIS air chamber. At the same time, the display input module 340 records the information of the entire air supply process, including key data such as air supply time and air supply volume, for subsequent review and analysis by management personnel. Through such a design, the control response unit can perform air supply operations efficiently and accurately to ensure the safe operation of GIS equipment. The innovation lies in the application of its electric air supply technology. Compared with the traditional mechanical air supply method, electric air supply is more accurate, fast and easy to control. At the same time, the design of the display and input module enables managers to view information and data of the gas replenishment process in real time, providing strong support for subsequent operation and maintenance management. The entire control response unit is connected to the intelligent gas replenishment unit through a remote communication module to realize remote control and monitoring functions.

[0033] In this embodiment, it should be noted that when the control response unit 300 receives a response instruction, the valve opening and closing module 320 will control the opening and closing of the corresponding valve, and then the electric air supply module 330 will supply air. In addition, the management personnel can use the display input module 340 to enter the storage information, and then upload it to the intelligent air supply unit 200 by the third communication module 310, and store the preset processing plan in the intelligent air supply unit 200.
