Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a three-station isolation mechanism. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits; motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] The three-position isolation mechanism in the distribution cabinet is a mechanical device that integrates the functions of a disconnect switch and a grounding switch.

[0004] Conventional three-position isolation mechanisms, due to design limitations, often struggle to adapt to diverse internal structural layouts of distribution cabinets while ensuring stable operation. Traditional isolation mechanisms may lack sufficient adjustability, requiring significant time and manpower to adjust other components within the distribution cabinet to accommodate the position and dimensions of the isolation mechanism during installation or maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a three-station isolation mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-position isolation mechanism, comprising a solid-sealed vacuum circuit breaker component and a first adjusting component. The solid-sealed vacuum circuit breaker component has fixed frame components connected and installed at both its upper and lower ends. The first adjusting component is connected and installed on one side of the upper end of the solid-sealed vacuum circuit breaker component via the fixed frame components. A knife switch component is connected to the top of the solid-sealed vacuum circuit breaker component, and a second adjusting component is connected and installed at the lower end of the solid-sealed vacuum circuit breaker component via the fixed frame components. The first adjusting component includes a first guide rail, a first slider, a first limit bolt, and a fixing seat. The surface of the first guide rail is provided with the first slider, and the top left and right ends of the first slider are vertically threaded with the first limit bolt. A fixing seat is provided in the middle of the top of the first slider.

[0007] Furthermore, the solid-sealed vacuum circuit breaker component includes a circuit breaker body, an insulating component, an isolating terminal, and a grounding terminal. The upper and lower ends of the circuit breaker body are both connected to insulating components, and the upper end of the circuit breaker body is connected to and installed with an isolating terminal through the insulating component. The lower end of the circuit breaker body is connected to and installed with a grounding terminal through the insulating component.

[0008] Furthermore, the fixing structure includes a first fixing frame, a second fixing frame, and an anti-slip pad. The second fixing frame is connected to the side of the first fixing frame near the solid vacuum circuit breaker component, and the anti-slip pad is affixed to the surface of the first fixing frame and the second fixing frame near the solid vacuum circuit breaker component.

[0009] Furthermore, both ends of the connection between the first fixing frame and the second fixing frame are provided with two sets of holes for bolt installation, and both ends of the first fixing frame away from the second fixing frame are provided with holes for bolt installation.

[0010] Furthermore, the first guide rail and the first slider are connected to each other by a slotted embedded structure, and the first slider and the fixed base are set as an integral structure, and the first fixed frame is movably installed on the front side of the first slider.

[0011] Furthermore, the switch component includes a support column, terminals, a double-stage damping hinge, and a switch body. Terminals are horizontally installed on both the left and right sides of the upper end of the support column, and a double-stage damping hinge is movably installed on the top of the support column. The switch body is connected to the top of the double-stage damping hinge.

[0012] Furthermore, the end of the guillotine body away from the dual-segment damping hinge is movably inserted into the middle of the isolation terminal, and the bottom of the support column is movably installed on the top of the fixed base.

[0013] Furthermore, the second adjusting component includes a second guide rail, a second slider, and a second limiting bolt. The second slider is mounted on the surface of the second guide rail, and the second limiting bolt is threaded vertically onto both the left and right ends of the bottom side of the second slider. The first fixing bracket is movably mounted on the front side of the second slider, and the first adjusting component and the second adjusting component are parallel to each other.

[0014] This utility model provides a three-station isolation mechanism, which has the following beneficial effects:

[0015] 1. This utility model, by providing a first adjusting component and a second adjusting structure, utilizes the slotted embedded structure between the first guide rail and the first slider in the first adjusting component to allow the first slider to slide smoothly on the first guide rail. The position of the first slider is fixed by a first limiting bolt, thereby achieving precise adjustment of the upper end of the solid-sealed vacuum circuit breaker component. Simultaneously, the second adjusting structure works in the same way to adjust the lower end of the solid-sealed vacuum circuit breaker component. This dual-adjustment design enhances the stability and flexibility of the isolation mechanism and allows the entire mechanism to adapt to different working environments and needs. Through the use of the above structure, the practicality and applicability of the isolation mechanism can be effectively improved, while ensuring the reliable operation of the isolation mechanism in the distribution cabinet. Within a certain range, it allows for flexible positional and structural adjustments based on the internal structural components of the distribution cabinet, thereby avoiding structural interference and ensuring the stable operation of each component.

[0016] 2. This utility model features symmetrically installed fixing frame components at both ends of the solid-sealed vacuum circuit breaker. This structural design provides stable support and fixation for the solid-sealed vacuum circuit breaker. The fixing frame design not only enhances the overall stability of the isolation mechanism but also improves the ease and accuracy of installation in the distribution cabinet. The connection between the first and second fixing frames utilizes a perforated structure to facilitate bolt tightening, ensuring a secure and reliable connection between the fixing frame components and the solid-sealed vacuum circuit breaker. Simultaneously, the anti-slip pads effectively prevent slippage or displacement of the fixing frame components during use, further enhancing the stability and safety of the isolation mechanism. This design makes the entire isolation mechanism more stable and reliable during use, extends its service life, and reduces maintenance costs.

[0017] 3. This utility model, through the structural arrangement of a solid-sealed vacuum circuit breaker component and a knife switch component, allows the knife switch body to flexibly flip on the support column via a double-segment damping hinge, thereby effectively connecting or disconnecting the isolation terminal. This design not only improves the convenience of operation but also helps ensure the safety and stability of the circuit connection. At the same time, the wiring terminal arrangement facilitates connection with external circuits, thereby achieving effective control of the entire power distribution system. Utilizing the above structural arrangement, the entire device has the structural stability, convenient operation, and wide applicability, while also improving the reliability and safety of the power distribution cabinet.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figures 1 to 6As shown, a three-position isolation mechanism includes a solid-sealed vacuum circuit breaker component 1 and a first adjusting component 3. The solid-sealed vacuum circuit breaker component 1 has fixed frame components 2 connected to both its upper and lower ends. The first adjusting component 3 is connected to the upper side of the solid-sealed vacuum circuit breaker component 1 via the fixed frame components 2. A knife switch component 4 is connected to the top of the solid-sealed vacuum circuit breaker component 1, and a second adjusting component 5 is connected to the lower end of the solid-sealed vacuum circuit breaker component 1 via the fixed frame components 2. The first adjusting component 3 includes a first guide rail 301, a first slider 302, a first limit bolt 303, and a fixing seat 304. The first slider 302 is arranged and installed on the surface of the first guide rail 301, and the first limit bolt 303 is vertically threaded onto both the left and right ends of the top side of the first slider 302. A fixing seat 304 is provided in the middle of the top of the first slider 302. The first guide rail 301 and the first slider 302 are interconnected by a slotted embedded structure. The slider 302 and the fixed base 304 are integrally formed. The first fixed frame 201 is movably installed on the front side of the first slider 302. The second adjusting component 5 includes a second guide rail 501, a second slider 502, and a second limit bolt 503. The second slider 502 is arranged on the surface of the second guide rail 501, and the second limit bolt 503 is vertically threaded on both the left and right ends of the bottom side of the second slider 502. The first fixed frame 201 is movably installed on the front side of the second slider 502. The first adjusting component 3 and the second adjusting component 5 are parallel to each other. The slotted embedded structure between the first guide rail 301 and the first slider 302 in the first adjusting component 3 allows the first slider 302 to slide smoothly on the first guide rail 301. The position of the first slider 302 is fixed by the first limit bolt 303. At the same time, the second adjusting component 5 works in the same way to adjust the lower end of the solid-sealed vacuum circuit breaker component 1.

[0027] like Figures 1 to 6As shown, the solid-sealed vacuum circuit breaker component 1 includes a circuit breaker body 101, an insulating component 102, an isolating terminal 103, and a grounding terminal 104. Insulating components 102 are connected to both the upper and lower ends of the circuit breaker body 101. An isolating terminal 103 is connected to the upper end of the circuit breaker body 101 via an insulating component 102, and a grounding terminal 104 is connected to the lower end of the circuit breaker body 101 via an insulating component 102. The switch component 4 includes a support column 401, wiring terminals 402, a double-stage damping hinge 403, and a switch body 404. Wiring terminals 402 are horizontally installed on both the left and right sides of the upper end of the support column 401. Furthermore, a double-stage damping hinge 403 is movably mounted on the top of the support column 401, and a switch body 404 is connected and mounted on the top of the double-stage damping hinge 403. The end of the switch body 404 away from the double-stage damping hinge 403 is movably inserted into the middle of the isolation terminal 103, and the bottom of the support column 401 is movably mounted on the top of the fixed base 304. The switch body 404 can be flexibly flipped on the support column 401 through the double-stage damping hinge 403, thereby realizing the effective connection or disconnection of the isolation terminal 103. This design not only improves the convenience of operation, but also helps to ensure the safety and stability of the circuit connection.

[0028] like Figures 1 to 6 As shown, the fixing frame 2 includes a first fixing frame 201, a second fixing frame 202, and an anti-slip pad 203. The second fixing frame 202 is connected to the side of the first fixing frame 201 closest to the solid vacuum circuit breaker 1. The anti-slip pad 203 is affixed to the surface of the first fixing frame 201 and the second fixing frame 202 closest to the solid vacuum circuit breaker 1. Two sets of holes for bolt installation are provided at both ends of the connection between the first fixing frame 201 and the second fixing frame 202. Holes for bolt installation are also provided at both ends of the side of the first fixing frame 201 away from the second fixing frame 202. The holes at the connection between the first fixing frame 201 and the second fixing frame 202 facilitate bolt fastening and ensure a firm and reliable connection between the fixing frame 2 and the solid vacuum circuit breaker 1.

[0029] In summary, as Figures 1 to 6 As shown, when using this three-station isolation mechanism, the first adjusting component 3 and the second adjusting component 5 are first installed in terms of structure. The first guide rail 301 and the second guide rail 501 are installed on the inner wall surface of the power distribution cabinet as needed, and the relative positions between the first adjusting component 3 and the second adjusting component 5 are adjusted at the same time.

[0030] After installation, the first adjusting component 3, through the slotted and embedded structure of its internal first guide rail 301 and first slider 302, achieves smooth and precise sliding adjustment of the first slider 302 on the first guide rail 301. The operator can easily move the first slider 302 to a predetermined position according to actual needs, and secure the first slider 302 by tightening the first limit bolt 303, thereby fixing the entire structure of the first adjusting component 3.

[0031] Meanwhile, the second adjusting component 5 also operates on the same working principle, ensuring flexible and stable adjustment of the lower end of the solid vacuum circuit breaker component 1. Then, the two sets of fixed frame components 2 are connected and combined with the first adjusting component 3 and the second adjusting component 5 respectively. Using the hole structure opened at the connection between the first fixing frame 201 and the second fixing frame 202 inside the fixed frame component 2, the fixed frame component 2 is firmly installed on the upper and lower ends of the solid vacuum circuit breaker component 1 with bolts. During this process, the anti-slip pads 203 on the surface of the first fixing frame 201 and the second fixing frame 202 can effectively prevent the fixed frame component 2 from sliding or displacing relative to the solid vacuum circuit breaker component 1 during installation and use.

[0032] Subsequently, by using the first fixing bracket 201 in conjunction with bolts, the upper and lower ends of the sealed vacuum circuit breaker component 1, which is connected to the fixing bracket component 2 at both ends, are fixedly combined with the front sides of the first slider 302 and the second slider 502 respectively.

[0033] Subsequently, the switch component 4 is installed. The bottom of the support column 401 of the switch component 4 is movably installed on the top of the fixed seat 304 in the first adjusting component 3, and it is ensured that the switch body 404 can be flexibly flipped on the support column 401 through the double-stage damping hinge 403. In this way, the switch body 404 can be flipped to the isolation terminal 103 as needed to achieve effective connection or disconnection of the isolation terminal 103. At the same time, the wiring terminal 402 is set to facilitate connection with external circuits, thereby realizing effective control of the entire power distribution system.

[0034] In actual use, operators can flexibly adjust the positions of the first adjusting component 3 and the second adjusting component 5 according to the internal structure and actual needs of the distribution cabinet to adapt to different working environments and needs. At the same time, the positions of the first slider 302 and the second slider 502 are precisely fixed by the first limit bolt 303 and the second limit bolt 503, ensuring the stability and reliability of the entire isolation mechanism.

Many modifications and variations will be apparent to those skilled in the art.
