Description

Technical Field

[0001] The present invention relates to the technical field of GIS equipment installation, and in particular to a GIS equipment installation planning and management method. Background Art

[0002] GIS equipment is gas-insulated switchgear, which combines all the primary equipment in a substation except the transformer, including circuit breakers, disconnectors, grounding switches, voltage transformers, current transformers, lightning arresters, busbars, cable terminals, and inlet and outlet bushings, into a whole through optimized design. GIS uses sulfur hexafluoride gas with good insulation performance as the insulation and arc extinguishing medium, so it can greatly reduce the size of the equipment and achieve miniaturization. At the same time, since all the live parts are sealed in inert SF6 gas and do not come into contact with the external environment, the reliability is greatly improved and it has excellent earthquake resistance.

[0003] GIS equipment has gradually become the preferred equipment in substation power facilities due to its compact design, high reliability and easy maintenance. The installation process of GIS equipment is complicated and requires strict quality control measures to ensure its long-term stable operation. The installation quality of GIS equipment directly affects the stability and safety of its operation in the power system.

[0004] In the process of research and practice on GIS equipment methods, the inventors of the present invention found that there are problems with lax supervision in the current GIS installation process, and minor defects of the equipment are not discovered and dealt with in a timely manner, which greatly affects the installation quality of the GIS equipment. At the same time, there is also insufficient monitoring and treatment of the construction site and the surrounding environment, resulting in failure to achieve the required cleanliness for the installation. When the staff enter the GIS installation room, the pollutants they carry on their bodies are not cleaned up, causing secondary pollution to the environment, making the environmental cleanliness worse, causing GIS equipment failures, and problems in the operation of the substation. Summary of the invention

[0005] The present invention provides a GIS equipment installation planning and management method, which can timely and fully clean the workers and the installation environment to meet the dust-free requirements, and monitor the installation process in real time to ensure the installation quality.

[0006] A GIS equipment installation planning and management method comprises the following steps: S1: Installation preparation, foundation inspection and positioning marking, staff familiarize themselves with the installation drawings and inspect the installation equipment and site; S2: Preparation of the GIS installation area, completion of earthwork excavation and filling, ground grinding operation area civil construction, installation of a fully enclosed mobile plant in the operation area; S3: The staff wears protective clothing and shoe covers and enters the air shower room, where the staff quickly cleans the debris they carry, and then enters the mobile plant to spray water and clean the floor of the mobile plant; S4: A mobile track is arranged in the mobile plant, on which a movable trolley is installed. An air purifier is installed on the trolley. The air purifier is used to remove dust and purify the indoor environment. An environmental detector is installed next to the air purifier to monitor the dust concentration in the surrounding area in real time. When the regional dust concentration reaches the required purification level, the GIS equipment is installed; S5: Install the integral transport unit. Use a crane to align the integral transport unit with the center line. When the three-phase integral transport units are adjusted, the integral transport unit and the busbar unit are connected according to the construction drawing, and the phase sequence and all dimensions meet the requirements of the drawing, weld the pads to the legs of the circuit breaker. S6: Vacuum extraction and equipment inflation. Select a suitable vacuum pump to extract the vacuum according to the capacity of the GIS equipment compartment. After the vacuum degree reaches the standard, clean the inflation pipeline and use SF6 gas to inflate the equipment. S7: Secondary cable laying: power cables, control cables and signal cables are laid in layers. Cables are dragged on the ground to ensure that the cable arcs at the bottom of the cabinet are consistent, the layers are clear, the cables are tied firmly, and the entrances are neat and uniform; S8: Grounding of GIS equipment. Confirm the specifications and dimensions of the grounding busbar. Use a scouring pad dipped in alcohol to remove the oxide layer on the surface of the docking surface. Then wipe it clean with a white silk cloth dipped in alcohol. Apply a thin layer of conductive paste on the docking surface to prevent oxidation of the contact surface. Then tighten it with bolts. After tightening the bolts, check the torque and draw the tightening mark.

[0007] Preferably, after the mobile factory building is installed in step S2, the doors and windows are tested for opening and closing multiple times to ensure that they are smooth and unobstructed, and necessary water tightness and air tightness tests are carried out to ensure that the doors and windows can still maintain good sealing performance under severe weather conditions such as wind and rain. After the main structure is completed, a comprehensive safety inspection is carried out, including structural stability and welding quality.

[0008] Preferably, in step S5, the busbar unit must be installed first. First, the busbar unit is deflated through the air charging and discharging valve, and a strong flashlight is used to check whether there are foreign objects in the cylinder. The inner surface of the cylinder and the inner and outer surfaces of the conductor are cleaned with an extended plastic tube of a vacuum cleaner. The insulating parts at the interface should be wiped with industrial clean paper, and the surface of the sealing ring should be wiped with lint-free paper and alcohol. A proper amount of alcohol is sprayed on a clean silk cloth, and the sealing groove is cleaned. Anti-corrosion silicone grease is applied to the flange surfaces on both sides, and grease is applied to the conductor contact part. Bolts are used to fasten the metal flange of the busbar.

[0009] Preferably, in step S3, the air shower room is equipped with multiple air shower smart sensors, and the air shower smart sensor network is connected to the central controller. The central controller system analyzes the pollution level and air shower effect in the air in real time, and controls the air shower equipment to adjust the wind speed and direction. Ultraviolet lamps are embedded in the walls of the air shower room to kill microorganisms on clothes. A positive pressure clean clothes changing room with an indoor pressure greater than that of the outdoor pressure is provided in front of the air shower room to ensure that the air can only flow outward to avoid external air pollution. The staff changes into special clean room work clothes and shoe covers in the changing room. The work clothes are made of antistatic materials to reduce dust adsorption and are designed to be disposable or easy to clean and disinfect.

[0010] Preferably, in step S4, the trolley is controlled by a central controller, a visual sensor is provided inside the installed air purifier, the air purifier is connected to the central controller, and the air purifier uses a visual manager to track the staff. When the visual sensor detects the movement of the staff, a signal is sent to the central controller, and the central controller controls the trolley to follow the movement of the staff, and the air purifier purifies the air in the installation area where the staff is located at any time.

[0011] Preferably, workers are equipped with smart bracelets during the equipment installation process. The smart bracelets receive data from the central controller. When entering the air shower room, the bracelets display reminders and vibrate to inform workers whether they have reached the standard for entering a high-cleanliness area, ensuring that each employee meets the cleanliness requirements before entering a critical working environment.

[0012] Preferably, the environmental detector installed in step S4 is used to detect dust concentration. The environmental detector is connected to the central controller through a network. The central controller sets a standard threshold value for dust concentration. When the dust concentration detected by the environmental detector reaches the set installation standard threshold value, the central controller control system automatically sends a message to the smart bracelet to notify the staff and controls the air purifier to stop working.

[0013] Preferably, intelligent sensors are integrated in the overall transport unit to monitor the vacuum degree, temperature, humidity, and dust level inside the equipment during the installation process in real time, and transmit the data to the central controller through the Internet of Things technology. The central controller system analyzes the situation during the installation process based on the data and adjusts the installation steps. The central controller sends the adjusted plan to the staff via the smart bracelet.

[0014] Preferably, in step S1, the foundation inspection before installation first checks the size, horizontal height and flatness of the embedded iron of the foundation according to the foundation drawing, checks the position and number of grounding terminals, checks the position, direction and size requirements of the cable trench, checks the size and position of the outlet window, and locates and marks the precise position of the GIS interval, and marks the center line of the interval and the center line of the busbar.

[0015] Preferably, during the installation of the GIS equipment, an external dust concentration sensor and an electric sprayer are arranged outside the mobile factory building. The external dust concentration sensor and the electric sprayer are network-connected to the central controller. According to the outdoor dust concentration monitored by the sensor, the electric sprayer is controlled to spray water around the installation area to achieve the purpose of dust reduction.

[0016] It can be seen from the above technical scheme that 1. Since the embodiment of the present invention adopts the arrangement of a mobile plant for installation, the installation cost is effectively reduced. At the same time, a mobile track is arranged in the mobile plant, and the trolley moves on the track as the staff moves. The trolley is provided with an air purifier and an environmental detector, which can perform dust removal and purification treatment on the environment where the staff is located, and monitor the surrounding dust concentration in real time, so that dust removal can be centralized, unnecessary dust removal can be reduced, and environmental pollution during the installation process can be effectively reduced; 2. Since the embodiment of the present invention strictly follows the steps of installation of the overall transport unit, vacuum extraction and equipment inflation, and secondary cable laying, the installation process steps are standardized, the work efficiency is improved, and the installation quality of the GIS equipment is guaranteed; 3. Since the embodiment of the present invention adopts the configuration of a smart bracelet, a high-precision dust concentration sensor, and a smart sensor device, real-time monitoring and management of the installation process are achieved, precise control is achieved, and dust can be strictly removed and reduced according to environmental conditions to ensure a dust-free environment for installation. The staff can adjust the installation steps in real time through notifications from the smart bracelet, thereby improving management efficiency and ensuring the installation quality of the GIS equipment; 4. Since the embodiment of the present invention strictly controls the key steps of grounding and busbar unit installation of the GIS equipment, it can ensure the dust-free installation of the equipment and ensure the safe operation of the installed GIS equipment.
