Description

Technical Field

[0001] This invention belongs to the field of insulated switchgear, specifically a miniaturized horizontally mounted fully insulated switchgear for a booster station. Background Technology

[0002] Currently, in the new energy market such as photovoltaic, wind power or energy storage, the high-voltage section generally adopts a two-unit vertically installed high-voltage switchgear, with one unit for incoming lines and one unit for outgoing lines.

[0003] Connecting the transformer or upstream grid-connected switch via high-voltage insulated cables wastes space on the high-voltage side and places certain requirements on the high-voltage side space of the substation, thereby increasing the overall size of the substation and making its high-voltage cabinet cost and space cost relatively high.

[0004] Existing related technologies use vertical switchgear that occupies a high space, making it prone to collapse and having poor stability. Therefore, a miniaturized horizontally mounted fully insulated switchgear specifically for substations is proposed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Given the following technical problems in the existing technology: the switchgear used in the existing related technologies is all vertical, which occupies a high space, is prone to falling over and has poor stability.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a miniaturized horizontally mounted fully insulated switchgear for a booster station, comprising an insulating gas chamber housing, an inlet and outlet bushing provided at the bottom of the insulating gas chamber housing, a top plate provided at the bottom of the insulating gas chamber housing, a temperature control mechanism provided on the top plate, and several mounting brackets installed on both the insulating gas chamber housing and the top plate;

[0008] The temperature control mechanism includes a temperature control plate, a mounting slot, and a filter seat. The temperature control plate is provided on the top plate, and several mounting slots are provided on the temperature control plate. The filter seat is provided on the mounting slots, and an airflow generating mechanism is installed on the lower side of the top plate.

[0009] The flow guiding mechanism includes an operating plate, a flow guiding plate, and a pull rod. The flow guiding plate is C-shaped. Several pull rods are evenly arranged on the upper side of the operating plate. There are two or more pull rods. The top of the pull rod is connected to the top plate by bolts. A flow guiding plate is arranged on each side of the operating plate.

[0010] The guide plate is made of beryllium copper alloy, and an elastic insulating sleeve is attached to the outside of the guide plate. The elastic insulating sleeve is made of butyl rubber.

[0011] As a preferred technical solution for a miniaturized horizontally mounted fully insulated switchgear for a booster station, the flow guiding mechanism is provided with an airflow generating component. The airflow generating component includes an airflow generating seat, a mounting ring, and a contact block. The airflow generating seat is composed of three stacked cylindrical structures, with the diameters of the three cylindrical structures decreasing sequentially from top to bottom. A fan assembly is provided on the inner side of the airflow generating seat.

[0012] The control panel has several mating holes recessed in the middle, which are inserted into the airflow generator seat. The diameter of the cylindrical structure at the top of the airflow generator seat is larger than the diameter of the mating holes. The bottom end of the airflow generator seat is threaded with an installation ring, the diameter of which is larger than the diameter of the mating holes. The top of the installation ring is provided with a contact block, which is made of rubber and abuts against the lower side of the control panel.

[0013] The inlet and outlet bushings are connected to the inner side of the insulating gas chamber shell, and the inlet and outlet bushings can be used to pass through the line.

[0014] As a preferred technical solution for a miniaturized horizontally mounted fully insulated switchgear for a booster station, the pull rod is provided with a mounting platform, the mounting platform is provided with a positioning column, the mounting platform is connected to the top plate by bolts, and the positioning column is inserted into the top plate;

[0015] The mounting platform allows the top of the pull rod to be fixed to the top plate with bolts, thereby allowing the control panel and the structure on the control panel to be fixed inside the insulating gas chamber shell.

[0016] As a preferred technical solution for a miniaturized horizontally mounted fully insulated switchgear for a booster station, the fan assembly includes a motor base and fan blades. The inner side of the airflow generating base is connected to the motor base via a connecting arm. A motor is installed inside the motor base, and the power output end of the motor is connected to the fan blades.

[0017] The motor drives the fan blades to rotate, and the fan blades generate airflow, which enters from the top of the insulating chamber shell and exits from the side of the insulating chamber shell. During this process, the airflow can carry away the heat of the equipment inside the insulating chamber shell, thereby cooling the equipment inside the insulating chamber shell.

[0018] Airflow enters through the filter seat, where the filter screen filters the airflow. The airflow is guided by the guide vanes to reach the bottom of the insulating chamber housing, cooling the electronic equipment fixed to the bottom of the insulating chamber housing, and then it is removed through the exhaust seat.

[0019] As a preferred technical solution for a miniaturized horizontally mounted fully insulated switchgear for a booster station, the top plate is provided with a mounting groove, and a filter mechanism is installed in the mounting groove;

[0020] The filtration mechanism includes a filter base, a contact block, a limiting block, and a filter screen. Several limiting blocks are provided on the lower side of the top plate. The limiting blocks are arranged around the mounting groove. The contact block is clamped to the outer side of the top of the filter base. The contact block abuts against the limiting block.

[0021] The limiting block restricts the position of the contact block, thus confining the filter seat to the inside of the mounting groove.

[0022] As a preferred technical solution for a miniaturized horizontally mounted fully insulated switchgear for substations, the insulating gas chamber housing is provided with exhaust seats on both sides, and the exhaust seats are recessed with several filter screen holes;

[0023] The airflow that absorbs heat from the electronic equipment inside the insulating chamber can be discharged through the filter holes on the exhaust seat.

[0024] The beneficial effects of the miniaturized horizontally placed fully insulated switchgear for booster stations of the present invention are as follows: by placing the insulating air chamber shell horizontally, it is more stably fixed on the ground surface and does not occupy too much space at a higher altitude above the ground.

[0025] By rotating the wheel, the lead screw is rotated, thereby adjusting the position of the end of the hinge rod. This changes the shape of the guide vane and its relative distance to the bottom of the insulating chamber housing, so that the airflow can flow as close to the bottom of the insulating chamber housing as possible, while also being compatible with electronic devices of different sizes and specifications.

[0038] like Figures 1-6 As shown, the present invention proposes a miniaturized horizontally mounted fully insulated switchgear for a booster station, comprising an insulating air chamber housing 1, an inlet / outlet bushing 3 at the bottom of the insulating air chamber housing 1, a top plate 5 at the bottom of the insulating air chamber housing 1, a temperature control mechanism on the top plate 5, and several mounting brackets 2 on both the insulating air chamber housing 1 and the top plate 5.

[0039] The temperature control mechanism includes a temperature control plate 6, a mounting groove 7, and a filter seat 8. The temperature control plate 6 is provided on the top plate 5, and several mounting grooves 7 are opened on the temperature control plate 6. The filter seat 8 is provided on the mounting groove 7. An airflow generating mechanism is installed on the lower side of the top plate 5.

[0040] The flow guiding mechanism includes an operation plate 9, a flow guiding plate 12, and a pull rod 15. The flow guiding plate 12 is C-shaped. Several pull rods 15 are evenly arranged on the upper side of the operation plate 9. There are two or more pull rods 15. The top end of the pull rod 15 is connected to the top plate 5 by bolts. A flow guiding plate 12 is arranged on each side of the operation plate 9.

[0041] The guide plate 12 is made of beryllium copper alloy, and an elastic insulating sleeve is attached to the outside of the guide plate 12. The elastic insulating sleeve is made of butyl rubber.

[0042] The airflow guiding mechanism is provided with an airflow generating component, which includes an airflow generating seat 10, a mounting ring 11 and a contact block 20. The airflow generating seat 10 is composed of three stacked cylindrical structures, the diameter of which decreases from top to bottom. A fan assembly is provided on the inner side of the airflow generating seat 10.

[0043] The operation plate 9 has several mating holes recessed in the middle, which are inserted into the airflow generator seat 10. The diameter of the cylindrical structure at the top of the airflow generator seat 10 is larger than the diameter of the mating holes. The bottom end of the airflow generator seat 10 is threaded with a mounting ring 11, the diameter of which is larger than the diameter of the mating holes. The top end of the mounting ring 11 is provided with a contact block 20, which is made of rubber and abuts against the lower side of the operation plate 9.

[0044] The inlet / outlet bushing 3 is connected to the inner side of the insulating gas chamber housing 1, and the inlet / outlet bushing 3 can be used to pass through the line.

[0045] The tie rod 15 is provided with a mounting platform 25, and the mounting platform 25 is provided with a positioning post 24. The mounting platform 25 is connected to the top plate 5 by bolts 26, and the positioning post 24 is inserted into the top plate 5.

[0046] Mounting platform 25 secures the top of pull rod 15 to top plate 5 with bolts 26, thereby allowing operating plate 9 and the structure on operating plate 9 to be fixed inside insulating gas chamber housing 1.

[0047] The fan assembly includes a motor mount 18 and fan blades 19. The inner side of the airflow generator 10 is connected to the motor mount 18 via a connecting arm. A motor is installed inside the motor mount 18, and the power output end of the motor is connected to the fan blades 19.

[0048] The motor drives the fan blades 19 to rotate, and the fan blades 19 generate airflow, which enters from the top of the insulating chamber housing 1 and exits from the side of the insulating chamber housing 1. During this process, the airflow can carry away the heat of the equipment inside the insulating chamber housing 1, thereby cooling the equipment inside the insulating chamber housing 1.

[0049] Airflow enters through filter seat 8, filter screen 22 filters the airflow, and airflow is guided by guide plate 12 to reach the bottom of insulating chamber housing 1, so that electronic equipment fixed at the bottom of insulating chamber housing 1 is cooled, and then removed through exhaust seat 4.

[0050] The top plate 5 is provided with an installation groove 7, and a filter mechanism is provided in the installation groove 7;

[0051] The filtration mechanism includes a filter seat 8, a contact block 20, a limiting block 21, and a filter screen 22.

The outer side of the top of the filter seat 8 is clamped to the contact block 20, and the contact block 20 abuts against the limiting block 21.

[0052] The limiting block 21 restricts the position of the contact block 20, so that the filter seat 8 is restricted to the inside of the mounting groove 7.

[0053] Both sides of the insulating air chamber shell 1 are provided with exhaust seats 4, and the exhaust seats 4 are recessed with several filter screen holes;

[0054] The airflow that absorbs heat from the electronic equipment inside the insulating gas chamber housing 1 can be discharged through the filter holes on the exhaust seat 4.

[0055] The electronic equipment inside the insulating gas chamber housing 1 includes a gas-insulated switch, which is based on prior art with application number CN200410088157.0.

[0056] A threaded sleeve 17 is provided on the lower side of the operation plate 9. The threaded sleeve 17 is threadedly connected to the lead screw 16. The bottom end of the hinge rod 14 is hinged to the upper side of the guide plate 12. The hinge rod 14 is connected to the end of the guide plate 12 away from the operation plate 9.

[0057] Rotating the wheel 13 causes the lead screw 16 to rotate, thereby adjusting the position of the end of the hinge rod 14. This changes the shape of the guide vane 12 and its relative distance to the bottom of the insulating chamber housing 1, so that the airflow can flow as close to the bottom of the insulating chamber housing 1 as possible while being compatible with the installation of electronic equipment of different sizes and specifications.

[0058] The specific implementation method is as follows: the motor drives the fan blades 19 to rotate, and the fan blades 19 generate airflow, which enters from the top of the insulating air chamber housing 1 and exits from the side of the insulating air chamber housing 1. During this process, the airflow can carry away the heat of the equipment inside the insulating air chamber housing 1, thereby cooling the equipment inside the insulating air chamber housing 1.

[0059] Airflow enters through filter seat 8, filter screen 22 filters the airflow, and airflow is guided by guide plate 12 to reach the bottom of insulating chamber housing 1, so that electronic equipment fixed at the bottom of insulating chamber housing 1 is cooled, and then removed through exhaust seat 4.
