Problems solved by technology

In the design and installation process of the high-voltage cabinet, it is first necessary to select the components that make up the high-voltage switchgear according to the needs of the user, and then design the high-voltage cabinet according to the components and their connection relationship to ensure that the components of the high-voltage switchgear are installed. After the high-voltage cabinets are spliced, a gap of 4mm is maintained between the two high-voltage cabinets that are spliced ​​with each other, thereby reducing the impact of arc faults. Therefore, the high-voltage cabinets of the same type can only be used to install the same high-voltage switchgear components, and different models The high-voltage cabinet is not universal
In the actual use process, some components may need to be added appropriately according to the use requirements. If the additional components are directly installed on the side wall of the cabinet through bolts, the bolts protruding from the outside of the cabinet will increase the number of joints. The gap between the high-voltage cabinets cannot meet the 4mm gap requirement between two high-voltage cabinets that are spliced ​​together. Therefore, the high-voltage cabinet body needs to be reprocessed to meet the 4mm gap requirement. It is very inconvenient to use and consumes a lot of energy. Time-consuming and costly

Embodiment 1

[0021] Such as figure 1 , figure 2 and Figure 4 As shown, the high-voltage cabinet structure described in this embodiment includes: a cabinet body 1 with an open front side and closed sides, a number of cabinet doors 2 are hinged on one of the side walls on both sides of the cabinet body 1, and each cabinet The door 2 can be closed on the front side of the cabinet body 1 after rotating around the hinge joint, and the cabinet door 2 is also provided with an observation window 21 . On both side walls of the cabinet body 1 are respectively provided with a number of first stretching bosses 51 for supporting and installing electrical components, such as image 3 As shown, the first stretching boss 51 is a circular truncated structure inwardly recessed by the side wall of the cabinet, and the concave surface of the first stretching boss 51 of the circular truncated structure forms a first receiving groove 513, and the circular truncated structure The small end surface of the fi...

Embodiment 2

[0023] The difference between this embodiment and the first embodiment is that the second stretching boss is used to replace the first boss 51 in the first embodiment, and several sidewalls on both sides of the cabinet body 1 are respectively provided for support and installation. Second extruded bosses for electrical components such as Figure 6 and Figure 7 As shown, the second stretching boss is composed of a round platform 522 bent to one side to form a second receiving groove 523 and a connecting plate 525 bent outward along the large end of the round platform 522 , and is set on the round platform 522 There is at least one second connection hole 521, and the electrical components are installed on the round table 522 through the bolts arranged in the second connection hole 521, and the bolt section extending into the second receiving groove 523 after passing through the second connection hole 521 will not It protrudes out of the second receiving groove 523 . At least t...

Embodiment 3

[0025]The difference between this embodiment and Embodiment 1 is that a number of first stretching bosses 51 and second stretching bosses 51 and second stretching bosses for supporting and installing electrical components are respectively provided on the side walls on both sides of the cabinet body 1. The structure of the first stretching boss 51 has been clearly described in the first embodiment, the structure of the second stretching boss has been clearly described in the second embodiment, and the rest of the structure is the same as that of the first embodiment, and will not be repeated here. In actual use, a plurality of first stretching bosses 51 can be reserved on both side walls of the cabinet body 1, so that a plurality of electrical components can be added according to usage requirements during use, and each added electrical component It can be installed on the reserved first stretching boss 51. In addition, the added electrical components can also be installed on the...

Abstract

The invention discloses a high-voltage cabinet structure. The high-voltage cabinet structure comprises a cabinet body, wherein the front side of the cabinet body is open, the other sides are closed, a plurality of cabinet doors are hinged to one side wall of two sides of the cabinet body, the cabinet doors rotate around connecting points and can be closed on the front side of the cabinet body, and a plurality of stretching bosses for supporting and mounting electronic components are arranged on side walls of the two sides of the cabinet body respectively; a plurality of plug-pull type protection plates are fixed on opposite side walls of side walls hinged with the cabinet body, and front ends of the plug-pull type protection plates extend out of the cabinet body respectively; a quick opening door lock is arranged on each cabinet door, a first bayonet matched with the corresponding quick opening door lock is arranged on each plug-pull type protection plate extending out of the cabinet door, when one cabinet door is closed on the cabinet body, the quick opening door lock on the cabinet door can be mutually locked with the first bayonet on the corresponding plug-pull type protection plate, and accordingly, the cabinet door is locked tightly. The high-voltage cabinet structure has the advantages that the use is convenient, the cost can be effectively reduced, and the high-voltage cabinet structure can be used for mounting various models of high-voltage switch gear components.

Description

technical field [0001] The invention relates to the field of high-voltage electrical cabinets, in particular to a high-voltage cabinet structure. Background technique [0002] High-voltage switchgear usually refers to AC switchgear operating in a power system with a voltage ≥ 3KV and a frequency ≤ 50HZ. It is mainly used for the control and protection of power systems such as power plants, substations, and industrial and mining enterprises. It is an important component of power transmission and distribution equipment. Its safe and reliable operation is of great significance to the safe and effective operation of the power system. High-voltage switchgear consists of circuit breakers, isolating switches, grounding switches, reclosers, breakers, load switches, contactors, fuses, and load switch-fuse combinations, contactor-fuse (F-C) composed of the above components Combined electrical appliances, isolating load switches, and fuse switches are combined. In the design and inst...
