Description

Technical Field

[0001] This utility model relates to the field of high and low voltage switchgear technology, and in particular to a modular combined high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is a complete set of electrical equipment used in power systems for receiving, distributing, controlling, and protecting electrical energy. It is widely used in power plants, substations, industrial enterprises, high-rise buildings, and other locations, and is one of the core pieces of equipment in the power transmission and distribution process. Its core function is to achieve safe management and flexible allocation of electrical energy at different voltage levels through its internal switching equipment, busbars, and protection devices.

[0003] To improve the ease of use of switchgear, modular electrical switchgear has emerged on the market. However, due to the large number of modular electrical cabinets and the messy cable arrangement, a modular high and low voltage switchgear is proposed to optimize the cable arrangement and avoid cable compression.

[0004] Existing patent (publication number: CN222563254U) discloses a modular high and low voltage switchgear. The modular switchgear primarily involves modularizing the cabinet, facilitating individual assembly and disassembly, and simplifying the disassembly process. This design connects different cabinets via bolts and fixing plates through their fixing holes, ensuring a more stable connection between the cabinets. To improve the rationality and consistency of wiring, cable entry is located at the back of the cabinet, allowing for separate entry of high and low voltage cables. Cable exit is located at the bottom of the cabinet, with cables led out from the back and routed through a U-shaped support plate. To optimize the connection of horizontal cables, through holes are provided on the side of the support plate, facilitating more convenient and stable wiring and achieving a rational layout. The support plate at the back also improves the heat dissipation of the switchgear, preventing cable compression and enhancing the overall stability and usability of the cabinet. Adjustable threaded rods are provided at the bottom of the cabinet to allow for fine-tuning of support legs, adapting the cabinet to different ground conditions and optimizing its usability.

[0005] To address the aforementioned issues, while existing patents offer solutions that can optimize cabinet usage limitations through the coordination of components such as support plates, in practical use, the cabinets within the same group need to be switched on and off sequentially, making the operation rather cumbersome. Summary of the Invention

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A modular high and low voltage switchgear includes an outer cabinet 1, a door panel 2 movably connected to the front end of the outer cabinet 1, an open cabinet 3 fixedly installed on one side of the interior of the outer cabinet 1, and a sealed cabinet 4 fixedly installed on the other side of the interior of the outer cabinet 1. A mounting shell 5 is fixedly installed on one side of the front door panel 2 of the outer cabinet 1, and a switching mechanism 6 is disposed inside the mounting shell 5. The switching mechanism 6 includes a mounting groove 601, which is formed in the inner wall of the mounting shell 5. A sealing plate 602 is movably connected to one side of the mounting groove 601, and a through rod 603 is inserted into the interior of the mounting groove 601. A fastening block 604 is fixedly installed on the outer wall of the rod 603. A fixed shell 605 is fixedly installed on one side of the front end of the sealed cabinet 4. The front end of the fixed shell 605 has an installation hole 606. A first spring 607 is fixedly installed on one end of the rod 603 that passes through the installation hole 606. A closing plate 608 is movably connected to one side of the fixed shell 605 at the front end of the sealed cabinet 4. A rotating rod 609 extends out of the inside of the closing plate 608. The rod 603 passes through the inside of the fixed shell 605. The fixed shell 605 forms an elastic structure with the rod 603 through the first spring 607.

[0029] By adopting the above technical solution, the combination of open cabinet 3 and sealed cabinet 4 firstly separates electrical equipment of different voltages and forms a modular form for easy separate maintenance later. At the same time, an outer cabinet 1 is set up to provide protection. When closed, the sealing plate 602 closes with the mounting shell 5 through the locking block, thereby sealing the mounting groove 601. The abutting rod 603 compresses the first spring 607 and passes through the mounting hole 606, allowing the fastening block 604 to fasten the door panel 2 and the sealing plate 608 to seal. The opening and closing can be achieved by switching on and off a single locking block, improving the overall ease of operation. When opening and closing, the sealing plate 602 opens and the abutting rod 603 loses its abutting force. The first spring 607 extends and the abutting rod 603 returns to its original position, thus leaving space for the door panel 2 and the sealing plate 608 to rotate and open.

[0030] Specifically, such as Figure 2 , Figure 4 and Figure 5As shown, the sealed cabinet 4 has a slot 7 inside, and the fixed shell 605 has a pushing mechanism 8 inside. The pushing mechanism 8 includes a second spring 801, which is fixedly installed on one side inside the fixed shell 605. One end of the second spring 801 is fixedly installed with a through block 802, and the outer wall of the through block 802 is fixedly installed with a positioning block 804. The fixed shell 605 has a limit groove 803 corresponding to the position of the positioning block 804. The outer wall of the door panel 2 is fixedly installed with a mounting bracket 805, and the outer wall of the mounting bracket 805 is rotatably connected with an abutment roller 806.

[0031] By adopting the above technical solution, when opening and closing, the second spring 801 elastically pushes the through-block 802, and with the cooperation of the limiting groove 803 and the positioning block 804, the through-block 802 pushes the closing plate 608 through the fixed shell 605. Through the rotational engagement and sliding engagement of the rotating rod 609 with the slot 7, it is convenient to open and close the sealing cabinet 4. When closing is required, the closing plate 608 is first allowed to adhere and penetrate into the interior of the sealing cabinet 4. Then, when closing the door panel 2, under the rotational abutment of the mounting bracket 805 and the abutment roller 806, the closing plate 608 can slide and penetrate into the fixed shell 605 to compress the second spring 801, which corresponds to the fastening block 604, making it easy to lock uniformly.

[0032] Working principle: First, based on different voltages and safety factors, an integrated cabinet is formed by open cabinet 3 and sealed cabinet 4. Open cabinet 3 is used to assemble low-voltage safe electrical equipment components, while sealed cabinet 4 is for high-voltage hazards and is uniformly protected by outer cabinet 1, forming an integrated modular structure for easy maintenance. When door panel 2 is closed, it axially inserts into the mounting groove 601. Then, sealing plate 602 is closed and fixed to mounting shell 5 by locking block. It can slide and compress the first spring 607, which is inserted into the mounting hole 606 of fixed shell 605, so that two fastening blocks 604 close door panel 2 and sealing plate 608, thereby opening and closing simultaneously, avoiding the trouble of individual operation. When disassembling, the sealing plate 602 is opened and the first spring... The elastic push of 607 allows the insertion rod 603 to slide, leaving enough space for the door panel 2 and the closing plate 608 to rotate and open. The closing plate 608 rotates and slides into the slot 7 via the rotating rod 609. After opening and closing, the second spring 801 elastically pushes the protruding block 802, and through the cooperation of the positioning block 804 and the limiting groove 803, the protruding block 802 slides and pushes the closing plate 608 away from the fixed shell 605, thus facilitating opening and closing. When the door panel 2 is closed, the mounting bracket 805 and the abutment roller 806 cooperate to correspond to and abut against one end of the closing plate 608, causing it to slide along the slot 7 via the rotating rod 609 and enter the interior of the fixed shell 605, so that it can be locked by the opening and closing mechanism 6 at the same time.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
