Description

Technical Field

[0001] This utility model relates to the field of vacuum circuit breaker technology, specifically to a complete set of branch-bound vacuum circuit breaker devices. Background Technology

[0002] With the proposal and implementation of the smart grid plan, the safety and reliability of the power grid have become the focus of power system construction. The smart grid requires the widespread application of advanced equipment and technologies to improve the performance of the transmission and distribution system and realize the automation and intelligent management of the distribution network. In the distribution network, especially the 10kV lines, due to their diverse structures, poor safety and reliability, frequent accidents and difficulties in finding them, branch line faults often affect the safe operation of the entire distribution network and even lead to the power outage of the entire main line, which seriously affects the reliability of power supply and the user's electricity experience. As a result, it is necessary to frequently inspect and maintain the vacuum circuit breaker complete set of equipment.

[0003] In the existing technology, the device needs to open its operating mechanism box during use to complete the specified operation and facilitate the later maintenance of internal components. However, in actual use, its operating mechanism box is only closed through a single protective door. Therefore, during the opening period, especially in rainy weather, the lack of a shielding plate on the top makes it easy for dust, rainwater and other external debris to enter the control cabinet from the top, causing contamination and corrosion to the internal electrical components. Therefore, there is a need to improve the branch boundary vacuum circuit breaker complete set of devices. Utility Model Content

[0004] The purpose of this utility model is to provide a complete set of branch-bound vacuum circuit breaker devices to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a complete set of branch-bound vacuum circuit breaker devices, including a vacuum circuit breaker body, an operating mechanism box provided on the top of the vacuum circuit breaker body, a conductive electrode post provided on the top of the vacuum circuit breaker body, a protective fixing mechanism provided on the front of the operating mechanism box, and a sealing mechanism provided inside the operating mechanism box;

[0006] The protective fixing mechanism includes a protective component and a fixing component, wherein the fixing component is disposed at the bottom of the protective component;

[0007] The protective assembly includes a fixed plate, which is fixedly connected to the top of the operating mechanism box. A rotating handle is rotatably connected to the right side of the fixed plate, and a rotating rod is fixedly connected to the left side of the rotating handle. A protective plate one is fixedly connected to the front of the rotating rod, and a protective plate two is rotatably connected to the bottom of the protective plate one. Rollers are rotatably connected to the left and right sides of the protective plate two. A limit frame is fixedly connected to the front of the operating mechanism box, and a hydraulic rod is rotatably connected between the rotating rod and the operating mechanism box. This facilitates protection when the operating mechanism box is not opened, preventing dust from entering the box.

[0008] Preferably, the limiting frame has a groove at the position corresponding to the roller, and the roller is movably connected in the groove to facilitate the movement of the second protective plate.

[0009] Preferably, the fixing plate has a hole at the position corresponding to the rotating rod, and the rotating rod is rotatably connected in the hole to facilitate the rotation of the rotating rod.

[0010] Preferably, the fixing component includes a positioning block, which is slidably connected to the inside of the operating mechanism box. A pull plate is fixedly connected to the left side of the positioning block, and a spring is fixedly connected between the pull plate and the operating mechanism box. A fixing frame is fixedly connected to the front of the second protective plate to facilitate fixing the second protective plate.

[0011] Preferably, a slot is provided at the position corresponding to the positioning block of the fixed frame, and the positioning block is inserted into the slot for easy insertion into the fixed frame.

[0012] Preferably, the sealing mechanism includes a sealing frame, which is fixedly connected to the inside of the operating mechanism box. A connecting frame is fixedly connected inside the sealing frame. A second spring is fixedly connected to the front of the connecting frame. A first sealing ring is fixedly connected to the front of the second spring. A sealing door is rotatably connected to the front of the sealing frame. A second sealing ring is fixedly connected to the back of the sealing door, which facilitates waterproofing when the operating mechanism box is not opened.

[0013] Preferably, a groove is provided at the position corresponding to the sealing ring 2, and the sealing ring 2 is inserted into the groove, which facilitates the improvement of the sealing effect at the sealing point.

[0014] Compared with the prior art, this utility model provides a complete set of branch-separated vacuum circuit breaker devices, which has the following beneficial effects:

[0015] This branch-type vacuum circuit breaker assembly, through its protective fixing mechanism, allows manual pulling of the pull plate to the left to release the second protective plate. Subsequently, by manually rotating the rotating handle, the second protective plate moves along the roller and limit frame guide, thereby opening its operating mechanism box. Simultaneously, during the rotation of its rotating rod, the hydraulic rod rotates and extends, causing the hydraulic rod to support the folded first and second protective plates outward. At this point, the second protective plate is positioned above the front of the operating mechanism box, thus protecting the operator from rain and dust from the top, preventing dust, rain, and external impurities from falling into the operating mechanism box from the top.

[0016] This branch-separation vacuum circuit breaker assembly, through its sealing mechanism, when its operating mechanism box is not open, uses the elastic force of spring two to push sealing ring one forward, so that sealing ring one abuts against sealing ring two, thereby improving the sealing effect at the connection and preventing dust and rainwater from entering the operating mechanism box.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1:

[0027] The vacuum circuit breaker body adopts the existing technology ZW20-12(F) / 630-20 outdoor high-voltage (sectionalizing) vacuum circuit breaker. Specifically, it is an intelligent device integrating four switching functions: vacuum circuit breaker, vacuum load switch, recloser, and sectionalizer. Its main configuration includes the vacuum circuit breaker body, EYK-12 controller, and external voltage transformer (double-sided PT optional in distribution network automation ring network lines). It is widely used in 10kV and 20kV urban and rural distribution network overhead ring network lines as a line protection switch, sectionalizing switch, and tie switch, enabling automatic load distribution and reconfiguration of the ring network line. In branch lines supplying large users, it can be used as a sectionalizing switch (commonly known as a watchdog timer), featuring remote management mode, protection control functions, and communication functions.

[0028] Based on existing technology, the control cabinet is closed only by a single protective door. Therefore, during opening, especially in rainy weather, the lack of a top shield allows dust, rainwater, and other external debris to easily enter the cabinet from the top, causing contamination and corrosion of the internal electrical components. Please refer to [link to relevant documentation]. Figure 1-6 This utility model provides a technical solution: a complete set of branch boundary vacuum circuit breaker devices, including a vacuum circuit breaker body 1, an operating mechanism box 2 is provided on the top of the vacuum circuit breaker body 1, a conductive electrode post 3 is provided on the top of the vacuum circuit breaker body 1, a protective fixing mechanism 4 is provided on the front of the operating mechanism box 2, and a sealing mechanism 5 is provided inside the operating mechanism box 2.

[0029] The protective fixing mechanism 4 includes a protective component 41 and a fixing component 42, with the fixing component 42 disposed at the bottom of the protective component 41;

[0030] The protective assembly 41 includes a fixed plate 411, which is fixedly connected to the top of the operating mechanism box 2. A rotating handle 412 is rotatably connected to the right side of the fixed plate 411, and a rotating rod 413 is fixedly connected to the left side of the rotating handle 412. A protective plate 415 is fixedly connected to the front of the rotating rod 413, and a protective plate 416 is rotatably connected to the bottom of the protective plate 415. Rollers 417 are rotatably connected to the left and right sides of the protective plate 416. A limit frame 418 is fixedly connected to the front of the operating mechanism box 2. A hydraulic rod 414 is rotatably connected between the rotating rod 413 and the operating mechanism box 2, which facilitates protection when the operating mechanism box 2 is not opened, thereby preventing dust from entering the box.

[0031] Furthermore, the limiting frame 418 and the roller 417 are respectively provided with grooves, and the roller 417 is movably connected in the groove, which facilitates the movement of the second protective plate 416.

[0032] Furthermore, holes are formed at the corresponding positions of the fixing plate 411 and the rotating rod 413, and the rotating rod 413 is rotatably connected in the holes, which facilitates the rotation of the rotating rod 413.

[0033] Furthermore, the fixing component 42 includes a positioning block 422, which is slidably connected to the inside of the operating mechanism box 2. A pull plate 423 is fixedly connected to the left side of the positioning block 422. A spring 424 is fixedly connected between the pull plate 423 and the operating mechanism box 2. A fixing frame 421 is fixedly connected to the front of the second protective plate 416 to facilitate fixing the second protective plate 416.

[0034] Furthermore, a slot is provided at the corresponding position of the fixed frame 421 and the positioning block 422, and the positioning block 422 is inserted into the slot for easy insertion into the fixed frame 421. Example 2:

[0035] Based on the existing technology's requirement for a sealing effect on the operating mechanism housing 2, please refer to... Figure 6 Furthermore, in conjunction with Embodiment 1, the sealing mechanism 5 includes a sealing frame 51, which is fixedly connected to the inside of the operating mechanism box 2. A connecting frame 52 is fixedly connected inside the sealing frame 51. A second spring 53 is fixedly connected to the front of the connecting frame 52. A first sealing ring 54 is fixedly connected to the front of the second spring 53. A sealing door 56 is rotatably connected to the front of the sealing frame 51. A second sealing ring 55 is fixedly connected to the back of the sealing door 56, which facilitates waterproofing when the operating mechanism box 2 is not opened.

[0036] Furthermore, a groove is provided at the corresponding position of the sealing frame 51 and the sealing ring 55, and the sealing ring 55 is inserted into the groove to improve the sealing effect at the sealing point.

[0037] In actual operation, when the device is in use, firstly, during daily use, when it is necessary to open the operating mechanism box 2, the pull plate 423 is manually pulled to the left using the protective fixing mechanism 4. This causes the pull plate 423 to simultaneously drive the positioning block 422 to completely disengage from the second protective plate 416, thereby releasing the fixation of the second protective plate 416. Subsequently, the rotating handle 412 is manually rotated, causing the rotating mechanism to rotate clockwise to the right. During this rotation, the first protective plate 415 is simultaneously pulled to rotate, thereby pulling the second protective plate 416 to move along the guide roller 417 and the limit frame 418. The mechanism is moved, thereby opening the operating mechanism box 2. Simultaneously, during the rotation of the rotating rod 413, the hydraulic rod 414 is driven to rotate and extend, thereby causing the hydraulic rod 414 to support the folded protective plate 1 415 and protective plate 2 416 outward. At this time, the protective plate 2 416 is positioned above and in front of the operating mechanism box 2, thus protecting the top from rain and dust during operation. At the same time, through the sealing mechanism 5, when the operating mechanism box 2 is not opened, the spring force of the second spring 53 pushes the sealing ring 1 54 forward, causing the sealing ring 1 54 to abut against the sealing ring 2 55, thereby improving the sealing effect at the connection and preventing dust and rainwater from entering the interior of the operating mechanism box 2.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
