Description

Technical Field

[0001] The utility model belongs to the technical field of electrical switch cabinets, and in particular to a split-type instrument box. Background Art

[0002] With the increasing demand for automation and intelligence in the power industry, as a key component of the power system, the intelligent upgrade of 10kV high-voltage switch cabinets has become an inevitable trend. The requirements for the high-voltage electrical design and control part are more complex. The types of electrical components, the number of components, and the amount of secondary wiring have increased significantly compared with before, which also leads to a significant increase in the workload of secondary wiring. The structural design and electrical design of the switch cabinet must cooperate and coordinate with each other. However, the traditional high-voltage switch cabinet has an integral cabinet structure, and all compartments are concentrated in the cabinet. The instrument room for installing electrical equipment is fixed in the cabinet, and the instrument box is not separated from the cabinet body. The secondary wiring work of the switch cabinet can only be carried out after the cabinet body is assembled, which greatly prolongs the assembly cycle. Moreover, the wiring work is very cumbersome. When installing personnel are wiring, they need to stand for high-altitude operations, with a large working intensity, a long waiting cycle for processes, a high wiring labor intensity, limited high-altitude operation space, and easy fatigue. High-altitude operations not only increase the working intensity and safety risks but also limit the overall assembly efficiency and increase the production cycle. In addition, the integral cabinet structure is for fixed installation. When a fault occurs, it is easy to affect adjacent equipment, and it is not convenient to inspect and cannot be replaced generically, which makes it difficult to repair and replace, replace components, and expand the project when a fault occurs on-site.

[0029] The following further describes the present utility model in detail with reference to the accompanying drawings:

[0030] See Figure 1 , the present utility model provides a split-type instrument box, including an instrument box 1 and a switch cabinet body 2. The instrument box 1 is detachably installed on the switch cabinet body 2 by screws. Reserved interfaces are provided on both the instrument box 1 and the switch cabinet body 2, realizing the modular docking of the instrument box 1 and the switch cabinet body 2, which is convenient for subsequent maintenance and upgrade.

[0031] The switch cabinet body 2 is composed of a solid frame, which is welded by angle steel or channel steel. The frame has good load-bearing capacity and stability, and can support and fix various internal devices and components. The switch cabinet body 2 is set in an L shape, and a position for installing the instrument box 1 is reserved on the cabinet side plate 7 of the L shape, ensuring that the instrument box can be firmly installed at the designated position. And installation holes are reserved. The cabinet side plate 7 is connected to the instrument box 1 by screws through the installation holes. A top cover plate 3 is provided on the top of the switch cabinet body 2, and fixing holes are opened on the top cover plate 3. The top cover plate 3 is connected to the instrument box 1 by screws through the fixing holes, which is used for fixing the upper part of the instrument box 1, so that the instrument box 1 is also effectively supported and fixed in the vertical direction. In order to enhance the structural strength of the switch cabinet body 2, a first reinforcing rib 4 and a second reinforcing rib 5 are provided inside the switch cabinet body 2, which are installed on the left and right side plates of the cabinet side plate 7, improving the overall stability of the cabinet body. At the same time, the left and right fixing holes of the instrument box 1 are reserved to ensure that the instrument box 1 can be firmly installed on the cabinet body. These three parts fix the instrument box 1 on the switch cabinet body 2, which is convenient for installation and disassembly. The top cover plate 6 of the circuit breaker chamber is arranged between the instrument box 1 and the circuit breaker chamber, and is fixedly connected to the cabinet side plate 7. While fixing the cabinet side plate, the instrument box 1 and the circuit breaker chamber are separated, avoiding interference and influence between them, and ensuring the electrical isolation and safety performance between the two.

[0032] The instrument box 1 is made of a sturdy metal material (such as cold-rolled steel plate), with good protection performance and electromagnetic shielding effect. Inside the box, there are reasonable partitions or brackets designed for installing and fixing various electrical components, such as instruments, controllers, and terminal blocks. Important electrical components are concentrated in the instrument box 1, which not only protects the components from the external environment but also facilitates centralized management and maintenance. At the bottom, side, and top of the instrument box 1, there are interfaces and mounting holes for docking with the switchgear body 2. These interfaces and mounting holes are processed according to the pre-designed positions and sizes to ensure precise docking with the switchgear body 2. The electrical components in the instrument box 1 are electrically connected to the components in the switchgear body 2 through terminal blocks and cables. To protect the internal components from the influence of the external environment such as dust and moisture, the joints of the instrument box 1 are sealed with sealing strips or sealants. At the same time, the box door is equipped with a dust-proof net and a gasket to ensure a good sealing effect when the box door is closed.

[0033] The design of the split-type instrument box and switchgear of the present utility model embodies the concepts of modularization, integration, and easy maintenance. Since the instrument box and the switchgear body can be processed separately, the two processes can be carried out simultaneously without interference, greatly improving the production efficiency. Through reasonable structural design, the installation and disassembly of the instrument box become very convenient. This is particularly important during daily maintenance, repair, or replacement of components. At the same time, through reserved interfaces, rib design, and reasonable partition layout, the efficient combination and stable installation of the instrument box and the switchgear are achieved. This design not only improves the overall performance and reliability of the equipment but also reduces the production and maintenance costs.

[0034] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
