Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to an electrical control cabinet. Background Art

[0002] An electrical cabinet is a cabinet that protects the normal operation of components. An electrical cabinet usually contains basic functions such as safety protection, operation control, line protection, and power management. At present, the interior of the electrical cabinet is a whole, and the electrical equipment is arranged and installed in the cabinet in sequence. The wiring of the electrical equipment is generally standardized along the inner wall of the cabinet. When there are many electrical equipment, the lines connected to the electrical equipment and the lines pulled in and out are more complicated. The wiring space of the existing electrical cabinet is only the adjacent intervals of the electrical equipment. When there are many lines, it appears crowded, and the lines are prone to overlapping. When the lines are subsequently inspected and maintained, it is necessary to search for the corresponding lines, which affects the convenience of maintenance. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-5 , an electrical control cabinet, comprising a cabinet body 1, a partition plate 2 is welded and installed at the middle left position of the cabinet body 1, the cabinet body 1 is divided into an equipment area 3 on the right and a wiring area 4 on the left by the partition plate 2, the cabinet body 1 has an opening on the front, a cabinet door 5 is hingedly installed at the equipment area 3 on the front of the cabinet body 1 through a hinge, a display panel 7 is installed on the cabinet door 5 near the top, according to specific needs, the display panel 7 can also be replaced by an observation window, which are conventional settings of existing electrical cabinets, so they are not described in detail, a cabinet door 2 6 is hingedly installed at the wiring area 4 on the front of the cabinet body 1 through a hinge, an equipment mounting frame 8 is welded and installed on the rear wall of the cabinet body 1 at the equipment area 3, a plurality of wire passing openings 9 are opened on the partition plate 2 at the upper and lower height positions corresponding to the equipment mounting frame 8, and the wire passing openings 9 are oblong openings;

[0027] A plurality of equally spaced wire outlets 10 are provided on the side wall of the wiring area 4 on the left side of the cabinet 1, a baffle 11 is provided at the position of the wire outlet 10, a plurality of fins 12 are integrally formed on the outer peripheral wall of the baffle 11, the outer ends of the fins 12 away from the baffle 11 are welded and fixed to the inner peripheral wall of the wire outlet 10 at the corresponding position, a base frame 14 is welded and installed on the outer bottom surface of the cabinet 1, and the base frame 14 is supported on the ground.

[0028] When in use, the electrical equipment is installed on the equipment mounting frame 8, and the equipment line first passes through the line port 9 to the wiring area 4, and then is classified according to the type of line or the outgoing direction. The baffle 11 on the corresponding position of the outlet 10 is chiseled open by utilizing the limited connection strength of the narrow surface of the fin 12, and the un-chiselled baffle 11 continues to serve as a shielding effect, and then the internal line is passed through the outlet 10 to pass through the cabinet 1 for wiring or the external line is pulled into the cabinet 1 for wiring. The equipment line is directly uniformly routed, wired and classified in the wiring area 4, which reduces the space occupied by the equipment line in the equipment area 3, making the equipment area 3 look simpler, and the line directly passes through the wiring area 4 instead of being routed in the equipment area 3, so the space occupancy rate of the equipment area 3 is reduced, and the installation volume or installation spacing of the equipment can be increased.

[0029] In this embodiment, an air inlet 25 and an air outlet 26 are respectively provided on the top surface of the cabinet 1 at positions corresponding to the equipment area 3 and the wiring area 4. An air inlet fan 23 and an air outlet fan 24 are boltedly installed on the top surface of the cabinet 1 at positions corresponding to the air inlet 25 and the air outlet 26. The air inlet fan 23 is arranged to blow air into the cabinet 1, and the air outlet fan 24 is arranged to blow air out of the cabinet 1. A plurality of ventilation holes 13 are provided on the partition 2 at positions staggered from the wiring opening 9.

[0030] The air inlet fan 23 sucks in external air and blows it into the equipment area 3. The air then enters the wiring area 4 from the ventilation holes 13 and is finally sucked and blown out by the air outlet fan 24. The air flow path is U-shaped, spanning the entire internal space of the cabinet 1 to ensure that the air maximizes the heat exchange surface of the electrical equipment, ensure the heat exchange efficiency and speed, reduce dead corners where air circulation is poor, and thus ensure the overall heat dissipation effect.

[0031] In this embodiment, a bellows 18 is installed on the inner wall of the right side of the cabinet 1 at the equipment area 3, and a connecting cover 19 is integrally installed on the top of the bellows 18. The top of the connecting cover 19 is arranged to abut against the air inlet 25. An air duct 22 is preset in the bellows 18. A plurality of flanges 20 with equal spacing are integrally installed on the side of the bellows 18 facing the partition 2. Air outlet holes 21 are opened on the flanges 20. The maximum air outlet volume of all the air outlet holes 21 is equal to the maximum air inlet volume of the air inlet 25. The air outlet holes 21, the air duct 22 and the air inlet 25 are connected.

[0032] When the air inlet fan 23 inhales the relatively cold external air, the air first circulates in the bellows 18 and then blows out from the air outlets 21. Due to the multiple settings of the air outlets 21, the air can directly blow to the equipment at different positions to ensure sufficient ventilation for the equipment, especially the equipment near the lower part of the cabinet 1, and reduce the impact of insufficient air flow in the non-main air circulation path caused by the two fans blowing and sucking, thereby ensuring continuous, reliable and stable heat exchange.

[0033] In the present embodiment, an air inlet duct 15 and an air outlet duct 16 are bolted to the outer sides of the air inlet fan 23 and the air outlet fan 24 on the top surface of the cabinet 1, and the pipe openings of the air inlet duct 15 and the air outlet duct 16 are both arranged toward the rear side of the cabinet 1. The cross-sections of the air inlet duct 15 and the air outlet duct 16 are both arranged in a "-shaped structure, and a protective net 17 is bolted to the pipe openings of the air inlet duct 15 and the air outlet duct 16.

[0034] The openings of the air inlet duct 15 and the air outlet duct 16 face backwards and are relatively directly open upward, which can reduce the amount of dust sucked in, especially when the fan is not working, further reducing the natural falling dust entering the cabinet 1. At the same time, other items such as filter cotton and filter elements can be added to the pipeline according to actual needs to filter the dust in the incoming air, providing an expandable space.
