Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinets, in particular to an electric control cabinet which is used in electric automation engineering and is easy to maintain. Background Art

[0002] An electrical control cabinet is a control cabinet that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, be easy to maintain, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of faults or abnormal operation, the circuit can be cut off or an alarm can be given with the help of protective electrical appliances. Various parameters in operation can be displayed with the help of measuring instruments, and certain electrical parameters can be adjusted. It can also prompt or send signals when deviating from the normal working state. It is often used in various power generation, distribution and substations.

[0003] At present, vents are generally set on the side of the electrical control cabinet to achieve heat dissipation, but the vents are relatively narrow and the heat dissipation efficiency is poor. When the load is too large, the heat in the cabinet cannot be dissipated in time, which will affect the life of the accessories. At the same time, external dust will gradually accumulate in the cabinet over time, reducing the heat dissipation efficiency and causing inconvenience for relevant personnel in cleaning and subsequent maintenance. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an electrical control cabinet for electrical automation engineering and easy to maintain, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: an electrical control cabinet for electrical automation engineering and easy to maintain, including a cabinet body, a cabinet door is installed on the front of the cabinet body, a heat dissipation port is opened on the back of the cabinet body, a rear baffle is arranged outside the heat dissipation port, a dust filter is clamped inside the rear baffle, and side baffles are connected to both sides of the cabinet body.

[0006] Optionally, the side baffles are symmetrically connected to both sides of the cabinet body, and a plurality of holes are opened on the side baffles, which can increase the distance between adjacent electrical control cabinets, thereby promoting heat dissipation.

[0007] Optionally, the rear baffle is connected to the back of the cabinet outside the heat dissipation port, and a card slot is provided on the rear baffle. The rear baffle is made of a metal material with good thermal conductivity and can be magnetically attracted, which facilitates the installation of the dust filter and also facilitates heat dissipation.

[0008] Optionally, the dust filter is movably inserted in the rear baffle, and blocks are connected on both sides of the dust filter, the blocks are magnetic, and the blocks are movably inserted and magnetically attracted in the slots. Sealing strips are connected to the sides of the dust filter, which can achieve a sealing effect and also improve the stability of the dust filter's snap-on installation. The dust filter is a dust-proof steel mesh, which can isolate external dust.

[0009] Optionally, the heat dissipation port is opened on the back of the cabinet, and the heat dissipation port is connected to the interior of the cabinet, and there are multiple heat dissipation ports evenly distributed, which can promote the heat dissipation effect.

[0010] The utility model provides an electrical control cabinet for electrical automation engineering and is easy to maintain, which has the following beneficial effects:

[0011] 1. The electrical control cabinet used in the electrical automation project and easy to maintain can achieve the effect of promoting heat dissipation and reducing the dust entering the cabinet by setting a dust filter, which is convenient for daily maintenance of the electrical control cabinet. At the same time, it can also prevent the problem of external dust entering the cabinet and affecting the distribution work. In addition, through the cooperation of the side baffle, the distance between adjacent electrical control cabinets can be increased to achieve the effect of promoting heat dissipation.

[0012] 2. The electrical control cabinet used in the electrical automation project and easy to maintain can promote heat dissipation by opening a heat dissipation port on the back of the electrical control cabinet, so that the heat inside the cabinet can be dissipated in time, avoiding the problem of overheating, aging or damage of accessories caused by untimely heat dissipation, thereby extending its service life. At the same time, through the cooperation of the dust filter, it can isolate dust and other impurities to realize the dustproof function of the device. At the same time, through the cooperation of the side baffle, it can avoid the problem of limited heat dissipation caused by the close contact of adjacent electrical control cabinets, thereby achieving the effect of promoting heat dissipation.

[0013] 3. The electrical control cabinet used in the electrical automation project and easy to maintain has a card slot on the rear baffle. At the same time, through the cooperation of the card block, the dust filter can be installed movably by magnetic attraction, thereby facilitating the disassembly and assembly of the dust filter, providing convenience for the later cleaning and maintenance of the electrical control cabinet.

[0014] 4. In short, the electrical control cabinet used in electrical automation projects and easy to maintain can increase the distance between the back of the electrical control cabinet and the wall, etc. through the cooperation of the heat dissipation port, the rear baffle and the dust filter, so as to provide sufficient space for heat dissipation, and at the same time can also achieve the effect of promoting heat dissipation while avoiding dust accumulation. The side baffle can increase the distance between the electrical control cabinet and the adjacent devices to accelerate the heat dissipation. The movable installation of the dust filter can facilitate the regular cleaning or replacement of the dust filter, which provides convenience for the maintenance of the electrical control cabinet.
