Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to an integrated reactive power compensation device. Background Technology

[0002] In electronic power supply systems, reactive power compensators are key devices for ensuring the stable and efficient operation of the power grid. Their core function is to significantly improve the power factor of the grid through precise adjustment, reducing losses in power transformers and transmission lines during power transmission. Due to their crucial role, reactive power compensators are widely used in power systems, typically installed inside power facilities such as distribution rooms and prefabricated substations, becoming an essential component for ensuring the economical and reliable operation of the power system.

[0003] In related technologies, an integrated reactive power compensation device includes a chassis, capacitors, reactors, composite switches, and circuit breakers. The circuit breakers and composite switches, as key control components, are located on the outer wall of the chassis for easy access during operation and maintenance. The capacitors and reactors, as core components for energy conversion and compensation, are fixedly installed inside the chassis due to their high requirements for the stability of the installation environment, forming a compact structure of "external operation and internal energy storage".

[0004] To improve the utilization rate of internal space in power distribution rooms, reactive power compensation devices are often installed in narrow areas such as corners. However, according to power system operation and maintenance specifications, these devices require regular inspection and maintenance. During maintenance, due to the limited space in corners, disassembly cannot be carried out directly; the entire device must first be moved to a wider area. While existing devices integrate components, the core components such as capacitors and reactors are quite heavy, resulting in an overall high weight. Manual movement not only requires significant manpower but also presents inconvenience and inefficiency, and may even damage components due to bumps during transport, hindering maintenance work. Therefore, there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an integrated reactive power compensation device to solve the problem of low efficiency of reactive power compensation devices in the above-mentioned related technologies when they need to be moved during maintenance.

[0006] The integrated reactive power compensation device provided in this application adopts the following technical solution:

[0007] An integrated reactive power compensation device includes a chassis with openings on the left and right sides. A reactor and a capacitor are fixedly installed inside the chassis. A circuit breaker and a composite switch are fixedly installed on the front side of the chassis. A base plate is fixedly installed at the bottom of the chassis. Several casters are fixedly installed on the bottom surface of the base plate, and a traction handle is rotatably connected to the front edge. Covers that seal the openings are detachably installed on the left and right sides of the chassis.

[0008] By adopting the above technical solution, a base plate with casters is fixed at the bottom of the chassis, and a traction handle is rotatably connected to the front of the base plate. Workers no longer need to expend a lot of manpower to move the device; they only need to hold the traction handle and use the casters to easily move the device from narrow areas such as corners of the power distribution room to wider areas. This significantly reduces labor costs, shortens handling time, and significantly improves the efficiency of movement before maintenance. At the same time, the combination of casters and the traction handle allows for flexible adjustment of the device's position, preventing damage to core components such as reactors and capacitors during handling and ensuring device safety. Furthermore, the removable covers on the left and right sides of the chassis do not affect the daily protection of internal components and can be easily removed during maintenance. Combined with external circuit breakers and composite switches, this approach balances the functional integrity and operational convenience of the device, further optimizing the maintenance process and improving overall operation and maintenance efficiency.

[0009] Optionally, the lower edge of the cover plate is rotatably connected to the lower part of the chassis, and the cover plate can be rotated upward to a vertical state and downward to a horizontal state; the chassis is provided with a fixing member to lock the cover plate in the vertical state, and a support member is provided above the base plate to support the cover plate in the horizontal state.

[0010] By adopting the above technical solution, the lower edge of the cover plate is rotatably connected to the lower part of the chassis, enabling bidirectional switching between vertically closed and horizontally open states. Combined with fixing and supporting components, this achieves both protection and ease of maintenance. In the vertical state, the fixing components lock the cover plate securely, blocking the chassis opening and protecting internal reactors and capacitors from external influences. In the horizontal state, the supporting components support the cover plate, forming a temporary operating platform. This solves the problem of needing to store disassembled covers separately, and provides space for placing tools or temporary operations during maintenance, eliminating the need for additional platform construction. This further optimizes maintenance processes in narrow areas, improves operational convenience, and avoids the risk of damage during cover plate disassembly and transportation, extending the service life of components.

[0011] Optionally, when the cover plate is in a vertical position, a fixing through hole is provided on the upper part, and a fixing screw hole is provided on the chassis that can coincide with the fixing through hole. The fixing component is a fixing bolt that passes through the fixing through hole and is screwed into the fixing screw hole.

[0012] By adopting the above technical solution, a fixing through hole is provided on the upper part of the cover plate in the vertical position. This hole, combined with the fixing screw holes on the chassis, allows for the locking of the cover plate by screwing in a fixing bolt. The structure is simple and the connection is stable. The bolt connection reliably restricts the rotation of the cover plate, ensuring effective sealing of the chassis opening in the vertical position and protecting internal components.

[0013] Optionally, the traction handle can be rotated to a vertically upward and tilted traction state and fixed. Two positioning rods located on both sides of the cover plate are slidably provided on the left and right sides of the chassis along the vertical direction. Elastic pressing members that drive the positioning rods to move upward are fixed on the left and right sides of the chassis. A control member is provided at the upper end of the positioning rod. When the traction handle is in the vertically upward state, the positioning rod can be driven to move downward through the control member, so that the lower end face of the positioning rod is flush with the bottom surface of the moving wheel.

[0014] By adopting the above technical solution, when the traction handle is vertical, the control component drives the positioning rod to move downwards, with its lower end flush with the bottom surface of the moving wheel. This increases the support point, improves the stability of the device during operation, and prevents it from being affected by external shaking. When the traction handle is tilted, the elastic compression component drives the positioning rod upwards and off the ground, without obstructing the rolling of the moving wheel, making it easy to drag the device using the traction handle. This linkage design balances the stability of the working state with the convenience of movement, making operation simple and efficient, and optimizing the user experience of the device.

[0015] Optionally, the elastic compression member includes a first spring in a compressed state, a guide block fixed on the chassis, and a protrusion plate fixed on the outer periphery of the positioning rod. The guide block has a guide hole for the positioning rod to pass through, and the protrusion plate is located above the guide block. The two ends of the first spring are fixedly connected to the sides of the guide block and the protrusion plate that are close to each other.

[0016] By adopting the above technical solution, the guide hole of the guide block provides vertical sliding constraint for the positioning rod, preventing the positioning rod from deviating and ensuring its precise up and down movement; the compressed first spring always generates an upward elastic force on the protruding plate, which can automatically drive the positioning rod to move up and off the ground when the traction handle is tilted and the control component is released from compression, without the need for manual operation, simplifying the preparation steps before movement; and the spring force is stable, which can ensure the positioning rod's reset function for a long time. The structure is simple and reliable, with low maintenance costs. It not only works with the traction handle to realize the linkage between the positioning rod and the movement state, but also improves the overall stability and ease of operation of the device.

[0017] Optionally, the control component includes a control rod whose two ends are respectively fixedly connected to the upper ends of the two positioning rods. When the traction handle is in a vertical state, an abutment rod located above the control rod is fixedly provided on its outer periphery in the horizontal direction. An abutment protrusion that can press against the top surface of the control rod is fixedly provided on the outer periphery of the abutment rod.

[0018] By adopting the above technical solution, the control rod connects two positioning rods, which can synchronously drive the positioning rods on both sides to move up and down, ensuring the balance of the support on both sides of the device; when the traction handle is vertical, the abutment rod on its outer periphery also becomes vertical, and the abutment protrusion can precisely press the top surface of the control rod, causing the positioning rod to move down through mechanical pressing transmission. Without additional power or complicated operation, the positioning rod can be quickly aligned with the bottom surface of the moving wheel, improving the stability of the device in application; and all components are mechanical structures, which are not prone to failure, which simplifies the operation process and ensures the long-term reliability of the linkage function, further optimizing the convenience of the device when switching between "stability" and "movement".

[0019] Optionally, a control plug is fixed on the bottom surface of the control rod, and a control slot is provided on the top surface of the cover plate when it is in the vertically upward state; the control plug can be inserted into the control slot when the cover plate is in the vertically upward state and the positioning rod moves down.

[0020] By adopting the above technical solution, when the positioning rod moves downward due to the vertical movement of the traction handle, the control block is simultaneously inserted into the control slot of the cover plate. This adds an extra mechanical limit on top of the fixing component locking the cover plate, preventing the cover plate from loosening due to external force shaking or accidental contact, and further ensuring the protection effect of the internal reactor and capacitor. Moreover, this linkage design requires no additional operation and can be completed automatically simply by the normal downward movement of the positioning rod. It does not increase the number of operation steps for the operator, but also enhances the fixation reliability of the cover plate in the application state. At the same time, it is compatible with the existing structure, taking into account both practicality and structural simplicity.

[0021] Optionally, the abutting protrusion has an elastic pad fixed on its bottom surface when the abutting rod is in a horizontal state.

[0022] By adopting the above technical solution, the elastic pad on the bottom surface of the abutting protrusion can buffer the hard contact when the abutting protrusion squeezes the control rod, avoiding wear caused by rigid collision and extending the service life of the component; at the same time, the elastic pad can increase the contact friction, reduce the relative sliding between the abutting protrusion and the control rod, ensure stable extrusion transmission, ensure accurate downward movement of the positioning rod, improve the reliability of the linkage structure, and requires no additional complicated operation, making it highly practical.

[0023] Optionally, the support includes a support plate rotatably mounted on the cover plate away from the edge of the chassis. When the cover plate is in a horizontal state, the support plate can be rotated to a vertically downward state. At this time, the bottom edge of the support plate is vertically fixed with an extension plate bent in a direction away from the base plate. When the cover plate is in a vertically upward state, the support plate can be rotated to a vertically upward state. At this time, the extension plate is located above the abutment rod. When the support plate supports the cover plate, the bottom surface of the extension plate is flush with the bottom surface of the moving wheel.

[0024] By adopting the above technical solution, when the cover plate is rotated to a horizontal position, the support plate can be rotated to a vertically downward position, with the bottom surface of the extension plate flush with the bottom surface of the moving wheel. This provides stable support for the horizontal cover plate, forming a temporary maintenance platform for easy placement of tools or operation. No additional support structure is required, solving the problem of insufficient operating space in traditional maintenance. When the cover plate is vertically upward, the support plate can be rotated to a vertically upward position, with the extension plate positioned above the abutment rod. This protects the abutment rod, abutment protrusions, and other linkage components from dust and collisions, reducing the risk of component damage. Furthermore, the bending structure and height design of the extension plate ensure both stability when supporting the cover plate and coverage when protecting the abutment rod, eliminating the need for additional support or protective components.

[0025] Optionally, a heat conduction port is provided on the top surface of the chassis, and a heat conduction fan is fixed on the inner wall of the heat conduction port; a flexible protective curtain is provided above the chassis, and several hooks are fixed on the opposite sides of the flexible protective curtain; the support plate can be rotated to a vertically upward position when the cover plate is in the vertically upward position, and the two extension plates are fixed on the sides that are close to each other at this time, with retaining rings for the hooks to engage.

[0026] By adopting the above technical solution, the heat-conducting fan efficiently dissipates heat from the chassis through the heat-conducting port, ensuring the stable operation of internal components; the flexible protective curtain can protect the heat-conducting fan, and its hooks cooperate with the retaining rings on the extension plate when the support plate is vertical, which can fix the protective curtain and the support plate at the same time, preventing the protective curtain from being lost and stabilizing the protective state of the support plate. No additional fixing structure is required, which takes into account heat dissipation, protection and structural stability, making operation convenient and improving the reliability of the device.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] A base plate with casters is fixed at the bottom of the chassis, and a traction handle is rotatably connected to the front of the base plate. Workers do not need to spend a lot of manpower to move the device. They only need to hold the traction handle and use the casters to easily move the device from narrow areas such as corners of the power distribution room to wide areas. This greatly reduces labor costs, reduces handling time, and significantly improves the efficiency of moving the device before maintenance. At the same time, the combination of casters and traction handle can flexibly adjust the position of the device and avoid damage to core components such as reactors and capacitors during handling, thus ensuring the safety of the device.

[0038] The present application will be further described in detail below with reference to all the accompanying drawings.

[0039] Example:

[0040] Reference Figure 1 and Figure 2 An integrated reactive power compensation device includes a chassis 1 with openings on the left and right sides. A reactor 11 and a capacitor 12 are fixedly installed inside the chassis 1. Covers 2 that seal the openings can be detachably installed on both the left and right sides of the chassis 1. A circuit breaker 13 and a composite switch 15 are fixedly installed on the front side of the chassis 1.

[0041] The chassis 1 is provided with a moving component 3 at the bottom. The moving component 3 includes a base plate 31 fixed to the bottom of the chassis 1. Four moving wheels 32 with braking function are fixed on the bottom surface of the base plate 31. A traction handle 33 is rotatably connected to the front edge. When the reactive power compensation device needs to be moved a short distance, the operator can drag the base plate 31 and the chassis 1 by holding the traction handle 33 and using the moving wheels 32.

[0042] Reference Figure 1 and Figure 2 The lower edge of the cover plate 2 is rotatably connected to the lower part of the chassis 1, wherein the cover plate 2 can be rotated upward to a vertical state and downward to a horizontal state; the chassis 1 is provided with a fixing member 4 for locking the cover plate 2 in the vertical state, and a support member 5 is provided above the base plate 31 for supporting the cover plate 2 in the horizontal state.

[0043] When the cover plate 2 is in a vertical position, a fixing through hole is provided on the upper part, and a fixing screw hole that can coincide with the fixing through hole is provided on the chassis 1. The fixing member 4 is a fixing bolt 41 that passes through the fixing through hole and is screwed into the fixing screw hole.

[0044] Reference Figure 2 The support member 5 includes a support plate 51 rotatably mounted on the edge of the cover plate 2 away from the chassis 1. When the cover plate 2 is in a horizontal state, the support plate 51 can be rotated to a vertically downward state. At this time, the bottom edge of the support plate 51 is vertically fixed with an extension plate 52 that bends away from the base plate 31. When the support plate 51 needs to support the cover plate 2, the bottom surface of the extension plate 52 is flush with the bottom surface of the moving wheel 32. At this time, the combined structure of the support plate 51 and the extension plate 52 can be used to support the cover plate 2 in a horizontal state.

[0045] Reference Figure 2 A hinge seat 311 is fixed on the front side of the substrate 31 and is rotatably connected to the lower part of the traction handle 33. The hinge seat 311 has several locking through holes, and the lower part of the traction handle 33 has a locking screw hole. The substrate 31 is provided with a locking bolt (not shown in the figure) that passes through the locking through hole and is screwed into the corresponding locking screw hole. When the locking bolt passes through different locking through holes, the traction handle 33 can maintain the corresponding rotation state. Therefore, the traction handle 33 can be rotated to the vertical upward and inclined traction states and fixed.

[0046] Reference Figure 2 and Figure 3 The chassis 1 is provided with a positioning component 6 on its exterior. The positioning component 6 includes two positioning rods 61 that slide vertically on the left and right sides of the chassis 1 and are located on both sides of the cover plate 2. The left and right sides of the chassis 1 are fixed with elastic pressing members 62 that drive the positioning rods 61 to move upward. The upper end of the positioning rods 61 is provided with a control member 63.

[0047] When the reactive power compensation device is in use, first move the device to the designated area, and then adjust the traction handle 33 to the vertical upward position. At this time, the traction handle 33 can drive the positioning rod 61 to move down through the control component 63, so that the lower end face of the positioning rod 61 is flush with the bottom surface of the moving wheel 32, thereby improving the installation stability of the reactive power compensation device at this time.

[0048] When the reactive power compensation device needs to be moved, the traction handle 33 is turned to the tilt position. At this time, the control component 63 releases the pressure on the positioning rod 61. At this time, there is a gap between the lower end face of the positioning rod 61 and the ground, which facilitates the movement and adjustment of the position.

[0049] Reference Figure 3 and Figure 4 The elastic extrusion member 62 includes a first spring 621 in a compressed state, a guide block 622 fixed on the housing 1, and a protruding plate 623 fixed on the outer periphery of the positioning rod 61. The guide block 622 has a guide hole for the positioning rod 61 to pass through. The protruding plate 623 is located above the guide block 622. The two ends of the first spring 621 are fixedly connected to the sides of the guide block 622 and the protruding plate 623 that are close to each other.

[0050] Reference Figure 4 and Figure 5 The control component 63 includes a control rod 631 whose two ends are fixedly connected to the upper ends of two positioning rods 61 respectively. When the traction handle 33 is in a vertical state, an abutment rod 34 located above the control rod 631 is fixedly provided on its outer periphery along the horizontal direction. An abutment protrusion 341 that can press against the top surface of the control rod 631 is fixedly provided on the outer periphery of the abutment rod 34. When the abutment rod 34 is in a horizontal state, an elastic pad 342 made of rubber is fixedly provided on the bottom surface of the abutment protrusion 341.

[0051] When the cover plate 2 is in the vertically upward position, the support plate 51 can be rotated to the vertically upward position, and the extension plate 52 is located above the abutment rod 34 at this time, so as to protect the abutment rod 34 and the abutment protrusion 341 and reduce the possibility of damage to the abutment rod 34 and the abutment protrusion 341 in this state.

[0052] Reference Figure 2 and Figure 3 A control plug 632 is fixed on the bottom surface of the control lever 631. When the cover plate 2 is in the vertical upward position, a control slot 21 located directly below the control plug 632 is opened on the top surface. When the cover plate 2 is in the vertical upward position and the positioning lever 61 moves down, the control plug 632 moves down synchronously and inserts into the control slot 21 to further lock the cover plate 2.

[0053] Reference Figure 6 and Figure 7 A heat conduction port 16 is provided on the top surface of the chassis 1, and a heat conduction fan 14 is fixed on the inner wall of the heat conduction port 16. A flexible protective curtain 7 is provided above the chassis 1 to protect the heat conduction fan 14. Hooks 71 are fixed on both opposite sides of the flexible protective curtain 7. When the support plate 51 is in a vertical downward state, the two extension plates 52 are fixed on the sides that are far apart from each other, and the hooks 71 are engaged.

[0054] When the reactive power compensation device is in use, the cover plate 2 is simultaneously in a vertically upward position. At this time, the operator can rotate the support plate 51 to a vertically upward position and then insert the hook 71 on the flexible protective curtain 7 into the corresponding locking ring 521. This can both fix the two support plates 51 in this state and protect the guide fan with the flexible protective curtain 7.

[0055] The implementation principle of this application embodiment is as follows:

[0056] Application state: First, rotate the cover plate 2 to the vertical position and screw the wing bolt through the fixing through hole into the fixing screw hole to lock it; then adjust the traction handle 33 to the vertical position, and the abutment protrusion 341 on the abutment rod 34 presses the control rod 631, causing the positioning rod 61 to move down, with its lower end flush with the bottom surface of the moving wheel 32, improving the stability of the device; then rotate the support plate 51 to the vertical upward position, at which time the extension plate 52 is located above the abutment rod 34 for protection. Finally, snap the hook 71 on the flexible protective curtain 7 into the retaining ring 521 on the extension plate 52, which can both fix the support plate 51 and protect the heat conduction fan 14 using the flexible protective curtain 7; and in the application state, the heat conduction fan 14 can dissipate heat for the chassis 1 through the heat conduction port 16.

[0057] Movement state: Loosen the locking bolt, turn the traction handle 33 to the tilted state and fix it. At this time, the abutment rod 34 disengages from the control rod 631, the first spring 621 resets and drives the positioning rod 61 to move upward, and the lower end of the positioning rod 61 creates a gap with the ground. The operator holds the traction handle 33 and drags the base plate 31 and the chassis 1 a short distance with the help of the braked moving wheel 32. After moving into position, lock the moving wheel 32 to brake.

[0058] Maintenance status: Adjust the traction handle 33 to the tilted position, the first spring 621 presses the positioning rod 61 to move upward, causing the control plug 632 to disengage from the control slot 21, and then release the locking of the fixing bolt 41 to the cover plate 2; then turn the cover plate 2 to the horizontal position and turn the support plate 51 to the vertical downward position. At this time, the support plate 51 and the extension plate 52 are used to support the support plate 51, and maintenance tools can be placed on the top surface of the support plate 51, improving the overall maintenance efficiency.

[0059] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
