Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet switch technology, specifically to a protective transfer switch for power distribution cabinets. Background Technology

[0002] A changeover switch is a low-voltage switch that switches between multiple circuits. In distribution cabinets, the changeover switch is an important electrical component used to control the on / off state of circuits and plays a crucial role in switching and conversion.

[0003] Chinese patent CN202332613U discloses a distribution cabinet transfer switch with a safety protection cover. The switch body is located on the control panel of the distribution cabinet, and the safety protection cover surrounds the switch body. The safety protection cover includes a housing and a cover movably connected to the housing, with the housing fixedly connected to the control panel of the distribution cabinet. While this device can protect the transfer switch inside the distribution cabinet, its operation presents several challenges. Since the transfer switch requires regular inspection and testing, the padlock, while serving to define permissions and responsibilities, necessitates unlocking the padlock before use. In emergencies, this additional step could delay the timely switching of critical equipment, affecting the stability and safety of the power system. Furthermore, the protective cover is inconvenient to install and remove, as it is fixed to the mounting plate, making subsequent disassembly difficult and hindering the replacement of the transfer switch.

[0004] It is evident that the current protective transfer switches for distribution cabinets still have technical problems that urgently need to be solved. They should be optimized to improve their reliability and ease of use. Therefore, more reasonable technical solutions are needed to solve the technical problems existing in the current technology. Utility Model Content

[0005] In order to solve some or all of the technical problems existing in the prior art, this utility model proposes a protective changeover switch for power distribution cabinets. The switch cover is connected to the mounting base, which facilitates opening and closing, and is also easy to install and adjust, making it convenient to use.

[0006] To achieve the above objectives, the changeover switch disclosed in this utility model can adopt the following technical solution:

[0007] A protective transfer switch for a distribution cabinet, comprising:

[0008] Mounting base, on one side of which a changeover switch body is mounted, and grooves are provided at both the top and bottom of the mounting base, with a through plate movably inserted and connected within the grooves;

[0009] Two through plates are connected to a lower plate and an upper plate at the ends away from the groove, respectively. The lower plate has a through groove, and the upper plate has a connecting groove. A protective plate is provided between the upper plate and the lower plate, and a switch cover is also provided between the upper plate and the lower plate.

[0010] The aforementioned protective transfer switch for distribution cabinets is installed using a mounting bracket, and the switch cover can be easily opened and closed, thereby achieving switch protection and meeting practical operational requirements.

[0011] Furthermore, the connection and installation of the protective plate can be achieved in various ways, and its structure is not limited to a single method. Here, we optimize and propose one feasible option: the protective plate is provided with a limiting strip, and both sides of the upper plate and both sides of the lower plate are provided with limiting grooves, with the limiting strip and the limiting groove corresponding to each other. When the above scheme is adopted, the limiting strip and the limiting groove slide together, and can be set as a T-slot, a T-strip, or other mating structure that can prevent loosening.

[0012] Furthermore, the switch cover can be configured in various ways, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: connecting blocks are fixedly connected to both sides of the top of the upper plate, and the switch cover is movably connected to the two connecting blocks. When the above scheme is adopted, the connecting blocks and the switch cover rotate to cooperate, thereby realizing the rotational opening and closing of the switch cover.

[0013] Furthermore, the arrangement and configuration of the interlocking plates can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: one of the interlocking plates has fixed blocks fixedly connected to both sides, and each fixed block is connected to a movable rod. When adopting the above scheme, the upper interlocking plate can be set according to this structure.

[0014] Furthermore, the movable rod cooperates with the fixed block to facilitate adjustment at the mounting base. This can be achieved through various methods, and the structure is not limited to a single one. Here, we optimize and propose one feasible option: the top end of each movable rod passes through the fixed block and is connected to a first limiting block; the bottom end of each movable rod is connected to a connecting seat; the connecting seat is connected to a screw rod; and the screw rod is connected to a fastening nut. When using the above scheme, the movable rod passes through the fixed block, and the connecting seat below it can be integrally formed, fixed by welding, or fixed by threaded connection, etc.

[0015] Furthermore, the two interlocking plates are connected and fitted together at the mounting base. Their mounting structure is not limited to a single option; here, an optimization is proposed, and one feasible choice is suggested: support blocks are fixedly connected to both sides of the other interlocking plate, and connecting posts are movably interlocked at the top of both support blocks. When adopting the above scheme, the lower interlocking plate can be set according to this structure.

[0016] Furthermore, the connecting column's structure can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the bottom end of each connecting column passes through the support block and is connected to a second limiting block, while the top end of each connecting column is fixedly connected to a limiting seat, and the limiting seat has a fixing groove. When adopting the above scheme, the connecting column passes through the support block, and the limiting seat above it is used to correspondingly cooperate with the connecting seat, thereby realizing the corresponding cooperation of the upper and lower insert plates.

[0017] Furthermore, the mating structure between the movable rod and the connecting column can be achieved through various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the movable rod and the connecting column are correspondingly mated, the connecting seat and the limiting seat are connected and mated, and the screw on the connecting seat extends into the fixing groove. The tightening nut is adjusted to make the connecting seat and the limiting seat fit tightly together. When adopting the above scheme, the adjustment and mating of the screw and the fixing groove can realize the adjustment setting of the upper and lower through plates, which is convenient for adaptation and installation.

[0018] Furthermore, the switch cover works in conjunction with the protective plate to form a protective structure, and can be opened for actual operation: when the switch cover is closed, the switch cover and the two protective plates are attached to form a closed space.

[0019] Furthermore, the mounting base can be fixed to the external mounting surface in various ways, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the groove is provided with a mounting hole, and the mounting base is connected and fixed to the external mounting surface through the mounting hole. When adopting the above solution, the mounting hole can be a threaded hole, a slotted hole, etc.

[0020] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:
