Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct with a plug-in box. Background Art

[0002] As an important part of the modern power transmission system, the design and application of the bus duct junction box reflects the progress and refinement of power engineering technology. Bus duct, as an efficient and large-capacity power transmission device, is widely used in industrial plants, high-rise buildings, data centers and other places that require a large amount of power supply. The bus duct achieves efficient transmission of electric energy through its continuous metal channel, reduces line losses and improves power supply reliability.

[0003] However, in actual applications, the bus duct needs to be connected to different electrical equipment to meet specific power needs, which requires the bus duct to be branched to form a complex power network. The bus duct plug-in box came into being. It realizes the rapid connection of the bus duct branch lines through plug-in, greatly improving the flexibility and scalability of the system.

[0004] The bus duct plug-in box is equipped with a circuit breaker that matches the current size to ensure the safety and stability of the power supply. The circuit breaker can quickly cut off the power supply when the current is abnormal to prevent electrical fires and electrical accidents. In addition, the design of the plug-in box also takes heat dissipation into consideration to ensure normal operation in high temperature environments and extend its service life.

[0005] On the technical level, the bus duct plug-in box adopts high-precision plug-in design and high-quality insulating materials to ensure the reliability and safety of electrical connections. The structural design of the plug-in box fully considers the seismic performance, and can remain stable in complex and changeable usage environments and is not prone to failure.

[0006] With the development of intelligent technology, bus duct junction boxes have also begun to incorporate intelligent elements, such as remote monitoring and automatic detection, making the management of power systems more intelligent and efficient. These intelligent designs not only improve the operating efficiency of the system, but also greatly reduce operation and maintenance costs.

[0007] In short, as an important accessory of bus duct, the technical content and application level of bus duct plug-in box directly reflect the degree of modernization of the power system. With the continuous advancement of science and technology, the bus duct plug-in box will become more intelligent and efficient, providing a more solid guarantee for the stable operation of the power system.

[0008] When the existing bus duct with a plug-in box is in use, the fully enclosed structure of the plug-in box protects the internal components from direct invasion of the external environment, such as dust, moisture, etc. to a certain extent. However, when maintenance or fault diagnosis is required in the later stage, the bolts need to be unscrewed one by one and the plug-in box needs to be opened. This not only increases the complexity and difficulty of the maintenance work, but also makes it inconvenient and time-consuming for maintenance personnel to work on site during maintenance work, which not only increases the maintenance cost, but also may cause new safety problems due to improper operation.

[0009] In summary, the reason why the existing bus duct technology with plug-in boxes has the above-mentioned shortcomings is mainly due to its fully enclosed design concept. Although this design concept improves the safety and reliability of the bus duct to a certain extent, it also limits the simplicity of maintenance operations. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3 The utility model provides a technical solution: a bus duct with a plug-in box, comprising a bus duct 1, a plug-in box 2 and a cover plate 3, wherein the plug-in box 2 is fixedly mounted on one side of the bus duct 1 by bolts, and the edge of one end of the cover plate 3 is hinged on one side of the plug-in box 2 by a hinge, and the other end of the cover plate 3 is connected to a quick opening and closing mechanism 400 connected to the plug-in box 2;

[0029] Through the mutual cooperation between the plug-in box 2, the cover plate 3 and the quick opening and closing mechanism 400 on the bus duct 1, a function of quickly opening the plug-in box 2 can be provided when maintenance or fault diagnosis work is required at a later stage, which can greatly simplify the maintenance process, significantly reduce the complexity and difficulty of the maintenance work, and significantly improve the convenience of maintenance work for maintenance personnel. It can diagnose and solve problems more efficiently and accurately, thereby shortening the maintenance cycle and improving maintenance efficiency.

[0030] In this embodiment, the quick opening and closing mechanism 400 is a structure for quickly opening the plug-in box 2 when maintenance or fault diagnosis work is required at a later stage.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the quick opening and closing mechanism 400 includes a limit block 401 fixedly installed on one side of the plug-in box 2 by bolts, and a hollow rectangular block 402 fixedly installed on the other end of the cover plate 3 close to the ground. The position of the hollow rectangular block 402 corresponds to the position of the limit block 401 one by one. The hollow rectangular block 402 is a rectangular structure with left and right end faces opened. Fixed side panels 403 are fixedly installed on the opening edges on both sides of the hollow rectangular block 402 by bolts. A pulling component is installed in the hollow rectangular block 402, and an elastic pushing component located in the hollow rectangular block 402 is installed on the pulling component. A limit component connected to the limit block 401 is connected to one side of the pulling component.

[0032] It should be noted that the pulling assembly includes a pulling rod 4041, a handle 4042 and a connecting protrusion 4043; one end of the pulling rod 4041 passes through one of the fixed side plates 403 and is slidably connected thereto, and extends to the outside of one of the fixed side plates 403 and is fixedly connected to the handle 4042, and the other end passes through the elastic pushing assembly and is fixedly connected to the inner side of the connecting protrusion 4043, so as to be able to stably drive the elastic pushing assembly to move.

[0033] It can be understood that the elastic pushing assembly includes an anti-slip concave round block 4051 and a reset spring 4052; the number of the anti-slip concave round blocks 4051 is two, one side of one anti-slip concave round block 4051 is fixedly connected to one side of the connecting protrusion 4043, and one side of the other anti-slip concave round block 4051 is fixedly connected to one side of one of the fixed side plates 403, and the two anti-slip concave round blocks 4051 are distributed in a mirror-symmetrical manner, and the reset spring 4052 is sleeved on the outer side of the pulling rod 4041 and is located between the opposite sides of the two anti-slip concave round blocks 4051, so that when the pull handle 4042 is pulled, the two anti-slip concave round blocks 4051 can be stably driven to move in a direction close to each other, and the reset spring 4052 can be elastically contracted.

[0034] In addition, the limiting assembly includes a sliding block 4061, a sliding rod 4062 and a limiting plug 4063; one side of the sliding block 4061 is fixedly installed on the inner wall of the hollow rectangular block 402 by bolts, the outer side of the sliding rod 4062 is slidingly connected to the inner side of the sliding block 4061, one side of the limiting plug 4063 is fixedly connected to one end of the sliding rod 4062, and the other end of the sliding rod 4062 is fixedly connected to one side of the connecting protrusion 4043, so that the limiting plug 4063 can be driven to move stably under the drive of the connecting protrusion 4043 and the sliding connection between the sliding rod 4062 and the sliding block 4061.

[0035] In this embodiment, the projection of the sliding rod 4062 in the first direction is a rectangle with a length of L and a width of D. The first direction is parallel to the axial direction of the pulling rod 4041. The length of the inner side of the sliding block 4061 is Q and the width is E. L=Q, D=E, so that the sliding rod 4062 can be stably and snugly connected to the inner side of the sliding block 4061.

[0036] It should also be noted that a limiting groove 407 for the limiting plug 4063 to fit and engage is provided on one side of the limiting block 401 close to the hollow rectangular block 402, so as to stably limit the movement of the cover plate 3 to facilitate maintenance work by the staff.

[0037] The working principle of the above embodiment is:

[0038] When the staff needs to perform maintenance or fault diagnosis work on the plug-in box 2 at a later stage, they first hold the handle 4042 and pull it in the direction away from the plug-in box 2. Since the sliding rod 4062 is fixed to the connecting protrusion 4043, and the sliding rod 4062 and the sliding block 4061 are slidably connected, when the pulling rod 4041 moves, it can stably drive the connecting protrusion 4043 to move in the direction away from the plug-in box 2, and make the two anti-slip concave round blocks 4051 approach each other, and the reset spring 4052 elastically contracts, and the limiting block 4063 moves with the sliding rod 4062. When the limiting block 4063 is separated from the limiting groove 407, the cover plate 3 can be opened by moving in a circular motion with the hinged position of its other end as the axis, so that the inside of the plug-in box 2 can be quickly inspected.

[0039] Compared with the prior art: the bus duct with a plug-in box, through the mutual cooperation between the plug-in box 2, the cover plate 3 and the quick opening and closing mechanism 400 on the bus duct 1, can provide a function of quickly opening the plug-in box when maintenance or fault diagnosis work is required in the later stage, which can greatly simplify the maintenance process, significantly reduce the complexity and difficulty of the maintenance work, and significantly improve the convenience of the maintenance work of the maintenance personnel. It can diagnose and solve problems more efficiently and accurately, thereby shortening the maintenance cycle and improving the maintenance efficiency. In addition, it also improves the overall reliability and stability of the existing bus duct with a plug-in box, reduces the potential risks caused by improper maintenance or delays, and provides a strong guarantee for long-term stable operation. It not only improves the maintenance efficiency, but also enhances the safety and reliability of the system, and solves the problems of complex and time-consuming maintenance work and increased cost of maintenance operations and high maintenance costs caused by the fully enclosed structure of the existing bus duct plug-in box.
