Description

Technical Field

[0001] The utility model relates to the field of auxiliary components for installing voltage transformers, and particularly relates to an installation structure for a 40.5 kV C-GIS gas-insulated inner cone voltage transformer. Background Art

[0002] When the existing 40.5 kV gas-insulated voltage transformer cabinet is set, the insulating gas is usually an environmental protection gas or sulfur hexafluoride gas. Specifically, when installing a voltage transformer in the voltage transformer cabinet, it is necessary to manually lift the voltage transformer for installation. This installation method completely relies on manual labor to complete the alignment and insertion of the voltage transformer plug and the docking socket, and the fixation of the voltage transformer after the insertion is in place. This leads to time-consuming and laborious installation operations with low efficiency. At the same time, there are also potential safety hazards during the installation process, and it is not convenient for subsequent adjustment and efficient on-site replacement. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems by providing an installation structure for a 40.5 kV C-GIS gas-insulated inner cone voltage transformer, which is provided with an installation guiding component. In this way, by vertically aligning the positioning studs of the installation guiding component with the positioning notches at the bottom of the voltage transformer body, three voltage transformer bodies can be accurately and limitedly placed on the voltage transformer operation platform. At the same time, by driving the voltage transformer operation platform to rise through the hydraulic mechanism body, the three voltage transformer bodies can be synchronously lifted and the installation operation can be completed, realizing the simultaneous installation of the three voltage transformer bodies. See the following for details.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An installation structure for a 40.5 kV C-GIS gas-insulated inner cone voltage transformer provided by the utility model includes a voltage transformer cabinet body and a voltage transformer body. On both sides inside the voltage transformer cabinet body, cabinet internal guiding components are installed and set. At the position above the cabinet internal guiding components inside the voltage transformer cabinet body, a plurality of transformer docking sockets are provided;

[0006] An installation guiding component is arranged outside the voltage transformer cabinet body. A plurality of the voltage transformer bodies are positioned and placed at the top of the installation guiding component. The number of the voltage transformer bodies corresponds to the number of the transformer docking sockets, and voltage transformer plugs for plugging and installing with the transformer docking sockets are arranged at the tops of the voltage transformer bodies. The plurality of voltage transformer bodies are synchronously lifted to complete the docking installation operation with the transformer docking sockets by means of the cooperation between the installation guiding component and the cabinet internal guiding component.

[0007] Preferably, the in-cabinet guiding assembly includes a horizontal guide rail and a vertical guide rail. The number of both the horizontal guide rail and the vertical guide rail is two. The horizontal guide rail and the vertical guide rail are respectively fixedly connected to both sides inside the voltage transformer cabinet body. And both the horizontal guide rail and the vertical guide rail are evenly rotatably connected with pulleys for guiding. The top end of the vertical guide rail is close to the bottom of the transformer docking socket, and a positioning locking point is arranged at the top of the vertical guide rail.

[0008] Preferably, the installation and guiding assembly includes an installation platform body and a voltage transformer operating platform. The top surface of the installation platform body is the voltage transformer operating platform. A plurality of voltage transformer bodies are placed side by side and limited on the top surface of the voltage transformer operating platform. Vertical limiting points are installed on both sides of the installation platform body. And when the installation platform body slides horizontally into the voltage transformer cabinet body along the horizontal guide rail, the vertical limiting points can slide upward along the vertical guide rail and be locked and limited by the positioning locking point. At the same time, the voltage transformer plugs of the plurality of voltage transformer bodies are lifted to be vertically aligned with the transformer docking sockets respectively.

[0009] Preferably, positioning notches are respectively formed at the peripheral corner positions of the voltage transformer body. Positioning studs are vertically fixed at the positions corresponding to the positioning notches on the voltage transformer operating platform. And the voltage transformer body is placed on the top surface of the voltage transformer operating platform in a way of being respectively aligned and matched through the positioning notches and the positioning studs.

[0010] Preferably, a hydraulic mechanism body for lifting and lowering the voltage transformer operating platform is fixedly installed inside the installation platform body. A pressure sensor for detecting the docking installation pressure value between the voltage transformer body and the transformer docking socket is installed on the bottom surface of the voltage transformer operating platform.

[0011] Preferably, a hydraulic mechanism operating rod for controlling the hydraulic mechanism body is arranged outside the installation platform body.

[0012] Preferably, the number of both the transformer docking sockets and the voltage transformer bodies is three.

[0013] Adopt the above-mentioned installation structure for a 40.5 kV C-GIS gas-insulated inner cone voltage transformer. Specifically, in the installation operation of the voltage transformer body, when the installation platform body enters the voltage transformer cabinet body, the installation platform body is slid along the horizontal guide rail to the vertical limit point and enters the vertical guide rail by pushing. Then, the voltage transformer operation platform is driven by the hydraulic mechanism body to lift along the vertical guide rail. During this process, the voltage transformer operation platform drives multiple voltage transformer bodies to rise and approach the transformer docking socket above. When the voltage transformer operation platform rises to the vertical limit point and is locked and limited by the positioning lock point, multiple voltage transformer bodies are lifted to be vertically aligned with the corresponding transformer docking sockets respectively. At this time, manually observe whether there is a deviation in the concentricity between the three transformer docking sockets and the corresponding voltage transformer plugs below. If there is a deviation, twist the voltage transformer body by hand for fine adjustment. After adjustment, manually unlock the state where the vertical limit point is locked and limited by the positioning lock point, and then continue to let the voltage transformer operation platform drive the voltage transformer body to rise. During this process, the voltage transformer plugs are respectively aligned and inserted into the corresponding transformer docking sockets. After the pressure sensor detects that the pressure during upward installation reaches the set value, a signal is given by the pressure sensor to cut off the hydraulic mechanism body, and then the height of the voltage transformer operation platform at this time is maintained. After that, the worker sequentially pre-tightens the installation bolts according to the installation hole positions, and then tightens the bolts diagonally after complete pre-tightening to complete the installation and fixation of the voltage transformer body. Then, operate the hydraulic mechanism body through the hydraulic mechanism control lever to lower and release the installation platform body, and finally take the installation platform body out of the interior of the voltage transformer cabinet body.

[0014] The beneficial effects are as follows: 1. The present utility model is provided with an installation and guiding component. In this way, by vertically aligning the positioning stud of the installation and guiding component with the positioning notch at the bottom of the voltage transformer body, three voltage transformer bodies can be accurately and limitedly placed on the voltage transformer operation platform. At the same time, by driving the voltage transformer operation platform to rise by the hydraulic mechanism body, three voltage transformer bodies can be driven to lift synchronously and the installation operation can be completed, realizing the simultaneous installation of three voltage transformer bodies, which is beneficial to shortening the installation time, reducing the operating manpower, and improving the operation safety.

[0015] 2. A cabinet guiding component is provided inside the voltage transformer cabinet. Through the horizontal guide rail of the cabinet guiding component, the installation platform body can be smoothly guided and translated into the voltage transformer cabinet. At the same time, by means of the vertical sliding of the vertical limit points on both sides of the installation platform body along the vertical guide rail of the cabinet guiding component, the vertical guiding and deviation correction of the lifting installation process of the voltage transformer body can be carried out, ensuring that the voltage transformer body can be stably lifted vertically until the plurality of voltage transformer plugs are respectively aligned with the corresponding transformer docking sockets, facilitating the smooth completion of the lifting installation of the voltage transformer body;

[0016] 3. By means of the cooperation between the vertical limit points of the installation and guiding component and the positioning and locking points of the cabinet guiding component, the voltage transformer operating platform can be automatically locked when it rises to the height where the voltage transformer plug is level with the transformer docking socket. Then, it is convenient for manual visual inspection to check whether the central positions of the voltage transformer plug and the transformer docking socket are aligned, and the concentricity of the voltage transformer plug and the transformer docking socket can be adjusted by manually rotating the voltage transformer body, ensuring the concentricity when the voltage transformer plug is inserted into the transformer docking socket and realizing the accurate insertion and installation of the voltage transformer body.

Detailed implementation manner

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present utility model.

[0024] See Figures 1 - 3 As shown in the figure, the present utility model provides an installation structure for a 40.5 kV C-GIS gas-insulated inner cone voltage transformer, including a voltage transformer cabinet body 1 and a voltage transformer body 5. On both sides inside the voltage transformer cabinet body 1, there are installed in-cabinet guiding assemblies 2. Above the in-cabinet guiding assemblies 2 inside the voltage transformer cabinet body 1, there are provided a plurality of transformer docking sockets 3. Specifically, the in-cabinet guiding assembly 2 includes a horizontal guide rail 204 and a vertical guide rail 202. The number of the horizontal guide rail 204 and the vertical guide rail 202 is two each. The horizontal guide rail 204 and the vertical guide rail 202 are respectively fixedly connected to both sides inside the voltage transformer cabinet body 1, and the horizontal guide rail 204 and the vertical guide rail 202 are both evenly rotatably connected with pulleys 203 for guiding. The top of the vertical guide rail 202 is close to the bottom of the transformer docking socket 3, and a positioning locking point 201 is provided at the top of the vertical guide rail 202. The purpose of such a setting is that through the horizontal guide rail 204 of the in-cabinet guiding assembly 2, the installation platform body 402 can be smoothly translated into the voltage transformer cabinet body 1. At the same time, by the way that the vertical limit points 406 at both sides of the installation platform body 402 slide vertically along the vertical guide rail 202 of the in-cabinet guiding assembly 2, the vertical guiding and deviation correction of the lifting installation process of the voltage transformer body 5 can be carried out, ensuring that the voltage transformer body 5 can be stably lifted vertically so that the voltage transformer plugs 501 respectively correspond to the corresponding transformer docking sockets 3, facilitating the smooth completion of the lifting installation of the voltage transformer body 5.

[0025] See Figures 1 - 3As shown in the figure, an installation and introduction component 4 is arranged outside the main body 1 of the voltage transformer cabinet. A plurality of voltage transformer main bodies 5 are placed at the top of the installation and introduction component 4 in a positioned manner. The number of voltage transformer main bodies 5 corresponds to that of the transformer docking sockets 3. And voltage transformer plugs 501 for plugging and installing with the transformer docking sockets 3 are arranged at the tops of the voltage transformer main bodies 5. The installation and introduction component 4 is used in cooperation with the in-cabinet guiding component 2 to synchronously lift the plurality of voltage transformer main bodies 5 to complete the docking installation operation with the transformer docking sockets 3. Specifically, the installation and introduction component 4 includes an installation platform main body 402 and a voltage transformer operating platform 407. The top surface of the installation platform main body 402 is the voltage transformer operating platform 407. A plurality of voltage transformer main bodies 5 are placed side by side and limited on the top surface of the voltage transformer operating platform 407. Vertical limiting points 406 are installed on both sides of the installation platform main body 402. And when the installation platform main body 402 slides horizontally along the horizontal guide rail 204 into the main body 1 of the voltage transformer cabinet, the vertical limiting points 406 can slide upward along the vertical guide rail 202 to be locked and limited by the positioning locking point 201. At the same time, the voltage transformer plugs 501 of the plurality of voltage transformer main bodies 5 are lifted to be vertically aligned with the transformer docking sockets 3 respectively. The function of such a setting is that through the cooperation between the vertical limiting points 406 of the installation and introduction component 4 and the positioning locking point 201 of the in-cabinet guiding component 2, the voltage transformer operating platform 407 can be automatically locked when it rises to the level where the voltage transformer plugs 501 and the transformer docking sockets 3 are at the same height. Then it is convenient for manual visual inspection to check whether the central positions of the voltage transformer plugs 501 and the transformer docking sockets 3 are aligned and to adjust the concentricity of the voltage transformer plugs 501 and the transformer docking sockets 3 to be consistent by manually rotating the voltage transformer main bodies 5. This ensures the concentricity when the voltage transformer plugs 501 are plugged into the transformer docking sockets 3 and realizes the accurate plugging and installation of the voltage transformer main bodies 5.

[0026] See Figures 1 - 3As shown in the figure, the following optimizations are made to the installation and import component 4. Positioning notches 502 are provided at the peripheral corner positions of the voltage transformer body 5. Positioning studs 405 are vertically fixed at the positions corresponding to the positioning notches 502 on the voltage transformer operation platform 407. The voltage transformer body 5 is placed on the top surface of the voltage transformer operation platform 407 by means of the positioning notches 502 and the positioning studs 405 being respectively aligned and matched. The number of the transformer docking sockets 3 and the voltage transformer bodies 5 is three each. With such a setting, it is convenient to accurately limit and place the three voltage transformer bodies 5 on the voltage transformer operation platform 407 by the vertical alignment of the positioning studs 405 of the installation and import component 4 and the positioning notches 502 at the bottom of the voltage transformer body 5. At the same time, by driving the voltage transformer operation platform 407 to rise by the hydraulic mechanism body 403, the three voltage transformer bodies 5 can be simultaneously lifted and the installation operation can be completed, realizing the simultaneous installation of the three voltage transformer bodies 5, which is beneficial to shortening the installation time, reducing the operating personnel, and improving the operation safety.

[0027] Optionally, a hydraulic mechanism body 403 for lifting and lowering the voltage transformer operation platform 407 is fixedly installed inside the installation platform body 402. A pressure sensor 401 for detecting the docking installation pressure value between the voltage transformer body 5 and the transformer docking socket 3 is installed on the bottom surface of the voltage transformer operation platform 407. With such a setting, it is convenient to drive the voltage transformer operation platform 407 to rise and fall by the hydraulic mechanism body 403, and at the same time, it is convenient to detect the pressure during the upward installation by the pressure sensor 401 and give a signal to cut off the hydraulic mechanism body 403 after the set value is reached. Further optionally, a hydraulic mechanism operating lever 404 for controlling the hydraulic mechanism body 403 is provided outside the installation platform body 402, so as to control the working state of the hydraulic mechanism body 403 by the hydraulic mechanism operating lever 404.

[0028] With the above structure, specifically in the installation operation of the voltage transformer body 5, when the installation platform body 402 enters the voltage transformer cabinet body 1, the installation platform body 402 is slid along the horizontal guide rail 204 to the vertical limit point 406 and enters the vertical guide rail 202 by pushing. Then, the hydraulic mechanism body 403 drives the voltage transformer operation platform to move upward along the vertical guide rail 202. During this process, the voltage transformer operation platform drives multiple voltage transformer bodies 5 to rise close to the upper transformer docking socket 3. When the voltage transformer operation platform 407 rises to the vertical limit point 406 and is locked and limited by the positioning lock point 201, multiple voltage transformer bodies 5 are lifted to be vertically aligned with the corresponding transformer docking sockets 3 respectively. At this time, manually observe whether there is a deviation in the concentricity between the three transformer docking sockets 3 and the corresponding voltage transformer plugs 501 below. If there is a deviation, twist the voltage transformer body 5 by hand for fine adjustment. After adjustment, manually unlock the state where the vertical limit point 406 is locked and limited by the positioning lock point 201, and then continue to let the voltage transformer operation platform 407 drive the voltage transformer body 5 to rise. During this process, the voltage transformer plugs 501 are respectively aligned and inserted into the corresponding transformer docking sockets 3. After the pressure sensor 401 detects that the pressure during the upward installation reaches the set value, the pressure sensor 401 gives a signal to cut off the hydraulic mechanism body 403, and then keep the height of the voltage transformer operation platform 407 at this time. After that, the worker sequentially pre-tightens the installation bolts according to the installation hole positions, and then fastens the bolts diagonally after complete pre-tightening to complete the installation and fixation of the voltage transformer body 5. Then, operate the hydraulic mechanism body 403 through the hydraulic mechanism control lever 404 to lower and release the installation platform body 402, and finally take the installation platform body 402 out of the voltage transformer cabinet body 1.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
