Technical Field

[0001] This utility model relates to the field of high voltage switchgear technology, specifically a high voltage switchgear that facilitates cable routing. Background Technology

[0002] High-voltage switchgear is a crucial piece of equipment in power systems used for power distribution, control, metering, and connecting and disconnecting loads. It is widely used in substations, industrial and mining enterprises, and various power supply locations. Internally, it typically houses various high-voltage components such as circuit breakers, disconnect switches, and instrument transformers. Due to its compact internal structure, numerous components, and complex electrical connections, wiring is often extremely difficult. Messy cables not only affect aesthetics but can also cause partial discharge, short circuits, and even equipment failure due to insufficient spacing and interference. Furthermore, it greatly hinders subsequent inspection, maintenance, and component replacement. Therefore, providing a high-voltage switchgear that facilitates cable routing and optimizes the internal wiring space is of practical significance for improving installation efficiency, operational reliability, and maintenance convenience.

[0003] In existing high-voltage switchgear technology, the strong overall structure of the cabinet, the compact internal space, and the fact that component installation and wiring must all be carried out in the limited space inside the cabinet often make it difficult for personnel to operate when installing large components or laying out complex wiring, resulting in poor visibility and accessibility. At the same time, traditional cabinets often do not have flexible modular installation and dedicated wiring channels, which means that multiple components or large-area panel disassembly is required when maintaining or changing wiring, increasing the complexity of maintenance and operational risks.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: A high-voltage switchgear for convenient wiring includes a switchgear body 101. The rear end of the switchgear body 101 extends inward from top to bottom and is provided with a first rear compartment 102, a second rear compartment 103, and a third rear compartment 104. A base plate 105 is attached to the bottom surface of each of the first, second, and third rear compartments 102. Support frame plates 106 are fixedly installed on both sides of the top of the base plate 105. The support frame plates 106 have a plurality of assembly holes 107 for fixing high-voltage components spaced apart on their upper and lower sides. Fixing holes 108 are spaced apart on both sides of the base plate 105. Bolts pass through the fixing holes 108 and connect them to the bottom surfaces of the first, second, and third rear compartments 102 and 103 to fix the base plate 105.

[0017] The above scheme, using a high-voltage cabinet as the main structure, can accommodate and support all internal components, forming a complete power distribution unit. The first, second, and third rear compartments, spaced vertically from top to bottom, divide the internal space of the high-voltage cabinet into multiple independent and clearly defined rear installation areas, facilitating the categorized installation and isolation of different high-voltage components. Base plates, respectively attached to the bottom surface of each rear compartment, provide a stable and movable mounting base for the components installed above. Support frames, fixed to both sides of the top of the base plates, provide a three-dimensional mounting bracket for the high-voltage components, enhancing installation stability and space utilization. Several assembly holes spaced apart on the support frames flexibly accommodate the installation and fixing needs of high-voltage components of different sizes and specifications, improving versatility. Fixing holes spaced apart on both sides of the base plates provide interfaces for bolt connections. Bolts passing through the fixing holes and connecting to the bottom surface of the rear compartments allow the base plates to be detachably fixed inside, enabling the overall pull-out and locking function of the base plates and their components, greatly facilitating external installation and subsequent maintenance.

[0018] In this embodiment, preferably, the first rear door 109, the second rear door 110, and the third rear door 111 are respectively installed at the corresponding openings of the first rear compartment 102, the second rear compartment 103, and the third rear compartment 104 via hinges.

[0019] With the above solution, the first, second, and third rear doors are installed at the openings of their respective rear compartments, allowing for independent opening and closing. This provides operators with direct access to the interior of each compartment, facilitating the inspection and maintenance of components within. Hinges ensure reliable opening and closing of these rear doors, guaranteeing both operational convenience and cabinet sealing.

[0020] In this embodiment, preferably, three side doors 112 are bolted to the left and right sides of the high-voltage cabinet body 101, respectively, opposite to the first rear compartment 102, the second rear compartment 103 and the third rear compartment 104.

[0021] The above solution, with three side doors bolted to the left and right sides of the high-voltage cabinet and opposite each rear compartment, provides operators with auxiliary passages to enter the rear compartments from the side of the cabinet. The side doors allow personnel to perform wiring, organization, and connection operations from the side when the bottom plate is pulled out and a cavity is formed inside the rear compartment, greatly improving the accessibility and convenience of wiring operations.

[0022] In this embodiment, preferably, the front end of the high-voltage cabinet body 101 is provided with a first front compartment 113, a second front compartment 114 and a third front compartment 115 extending inward from top to bottom.

[0023] By using the above scheme, by extending the first front compartment, the second front compartment, and the third front compartment inward from top to bottom at intervals at the front of the high voltage cabinet, multiple independent front installation areas can be formed at the front of the high voltage cabinet. This allows high voltage components to be arranged in front and back compartments according to function or type, realizing front and back zone management, making the overall structure clearer and the operation objectives more specific.

[0024] In this embodiment, preferably, partitions 116 are fixedly installed between the first front compartment 113 and the first rear compartment 102, between the second front compartment 114 and the second rear compartment 103, and between the third front compartment 115 and the third rear compartment 104.

[0025] By fixing partitions between the first front compartment and the first rear compartment, between the second front compartment and the second rear compartment, and between the third front compartment and the third rear compartment, the front and rear compartments can be physically separated, effectively preventing electrical interference and physical contact between different compartments, ensuring the independence and safety of the operation of components in each zone, and enhancing the overall structural strength of the cabinet.

[0026] In this embodiment, preferably, the first front door 117, the second front door 118, and the third front door 119 are respectively installed at the corresponding openings of the first front compartment 113, the second front compartment 114, and the third front compartment 115 via hinges.

[0027] The above solution involves installing the first, second, and third front doors via hinges at the corresponding openings of the first, second, and third front compartments, respectively. This allows each front compartment to be opened and closed independently, facilitating operators' access to and maintenance of the high-voltage components installed inside the front compartments from the front. This achieves dual-channel operation from the front and back without interference, improving maintenance efficiency and operational safety.

[0028] In this embodiment, a high-voltage cabinet body 101 with convenient wiring is used. The rear end of the high-voltage cabinet body 101 extends inward from top to bottom, providing a first rear compartment 102, a second rear compartment 103, and a third rear compartment 104 at intervals. Each rear compartment has a base plate 105 attached to its inner bottom surface. The base plate 105 is connected to the corresponding rear compartment's inner bottom surface via fixing holes 108 on both sides and through bolts, forming a fixed and detachable installation structure. Support frame plates 106 are fixedly installed on both sides of the top of the base plate 105. The support frame plates 106 have several assembly holes 107 for fixing high-voltage components. Before installing the high-voltage components, the bolts can be removed to pull the base plate 105 out of the rear compartment, allowing the high-voltage components to be installed outside the cabinet on the support frame plates 106. This design significantly improves the convenience of component assembly and operating space.

[0029] Meanwhile, three side doors 112 are bolted to the left and right sides of the high-voltage cabinet body 101, opposite to each rear compartment. With the base plate 105 pulled out, opening the side doors 112 creates an unobstructed cavity inside the rear compartment, facilitating initial wiring layout and routing adjustments. After wiring is completed, the base plate 105 with installed components is pushed back into the rear compartment and bolted back to the bottom. At this point, only the laid-out wiring and high-voltage components need to be finally connected to complete the overall installation. The front end of the high-voltage cabinet body 101 also extends inwards from top to bottom, with a first front compartment 113, a second front compartment 114, and a third front compartment 115 spaced apart. Each front compartment is fixedly connected to its corresponding rear compartment by a partition 116, forming independent functional areas at the front and rear. The first front compartment 113, the second front compartment 114, and the third front compartment 115 are respectively fitted with a first front door 117, a second front door 118, and a third front door 119 via hinges at their corresponding openings. Similarly, the first rear compartment 102, the second rear compartment 103, and the third rear compartment 104 are respectively fitted with a first rear door 109, a second rear door 110, and a third rear door 111 via hinges at their corresponding openings, facilitating front and rear operations and maintenance. The high-voltage cabinet body 101, through its detachable sliding base plate 105 structure and the combination of multiple compartments and doors, achieves separation between the installation of high-voltage components and the wiring process, effectively improving the accessibility of the cabinet space and the convenience of wiring operations, while ensuring the overall integrity and structural stability of the component arrangement.
