Description

Electrical control cabinet convenient to overhaul

Technical Field

The invention relates to the field of electrical equipment, in particular to an electrical control cabinet convenient to overhaul.

Background

The control cabinet is formed by assembling switch equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements, and the arrangement of the control cabinet meets the requirements of normal operation of an electric power system, is convenient to overhaul and does not endanger the safety of people and surrounding equipment. In normal operation, the circuit can be switched on or off by means of a manual or automatic switch. When the fault or abnormal operation occurs, the circuit is cut off or an alarm is given by the aid of the protective electric appliance. The measuring instrument can display various parameters in operation, and can also adjust some electrical parameters to prompt or send out signals for deviation from normal working state. It is commonly used in various power generation, distribution and transformation substations.

However, since the electrical components are installed inside the control cabinet, when the internal components of the control cabinet are inspected, the components are affected by the two side walls, and thus, maintenance personnel cannot inspect all the components comprehensively. Simultaneously, the in-process of maintenance receives the influence of switch board both sides wall, and maintenance personal's arm home range receives serious restriction, and the operation is very inconvenient, influences the efficiency of maintenance work, especially is located the electrical components of upper position, even if also hardly maintains using the ladder. In addition, the existing electric cabinet body has poor internal heat dissipation capability and is easy to cause potential safety hazards. Inert gas is generally filled into the interior of the explosion-proof electrical control cabinet for protection, and when the cabinet body is opened, the inert gas can escape, so that oxygen deficiency of workers can be caused by careless operation. In addition, the control cabinet filled with inert gas is a closed space, which is difficult to overhaul and inconvenient to remove dust. The removal wheel setting of current switch board is at the switch board lower extreme, and the inconvenient position of fixed switch board when overhauing the switch board.

Therefore, a control cabinet which is convenient to maintain and has good heat dissipation is urgently needed, and the control cabinet is disclosed in the Chinese patent publication No.: CN215221375U, the name of the invention is: the utility model provides an electrical control cabinet convenient to use maintenance, an electrical control cabinet convenient to use maintenance is disclosed, including the supporting legs, the electrical control cabinet body, sliding base frame and switch board door, the internal portion both ends of electrical control cabinet welded fastening all around have the sliding base frame, sliding base frame top center department has seted up fixed spout, the last movable joint that lies in of sliding base frame has fixed slider in the fixed spout, welded fastening has the fly leaf between the fixed slider top, there is the bracing piece through bolt fixed mounting between fly leaf one side all around, there are a plurality of mounting panel through bolt fixed mounting on the internal bracing piece that lies in of electrical control cabinet. The disadvantages are that: the control cabinet created by the invention is open, the internal heat dissipation effect is poor, inert gas cannot be introduced, and the upper sliding base is not easy to maintain and has the risk of falling.

The invention provides an electric control cabinet convenient to overhaul, which is characterized in that the inner part of a cabinet body is sealed through a sealed inner side plate, a movable outer side plate and a partition plate, inert gas can be introduced, the inert gas can be removed and discharged through external movement, the interior of the cabinet body is convenient to check, the compatibility is strong, and the heat dissipation effect is good. And the partition plate not only can be independently drawn out of the cabinet body, but also can be matched with the ladder to be used as a ladder, so that the upper-layer partition plate is convenient to maintain.

Due to the existence of the ratchet wheel, the telescopic device 9 and the linkage rod 15 can only act on the scraping brush 13 in one direction, and the scraping brush 13 cannot drive the telescopic device 9 and the linkage rod 15 to move.

The working principle is as follows:

1. under a normal state, the inner side plate 5, the upper shell 2, the lower shell 3 and the cabinet door 4 seal the inner space of the cabinet body 1, inert gas is introduced for protection, at the moment, the exhaust fan 302 does not operate, the electromagnet is electrified to attract the fan blades 303, the fan blades 303 are superposed with the accommodating groove, and the ventilation pipe 301 is sealed;

2. when the cabinet body 1 needs to be overhauled, the exhaust fan 302 operates, the fan blades 303 rotate to generate upward buoyancy, the fan blades 303 move upward along the floating shaft 306 and are separated from the accommodating groove, outside air is drawn into the cabinet body 1 from the through holes to dilute inert gas or dissipate heat, then the expansion device 9 is controlled to pull the outer side plate 6 upward, when the outer side plate 6 is just pulled, the elastic heat conductor 10 is stretched, if no problem is found, the expansion device 9 is closed, and the outer side plate 6 can rapidly fall under the elastic action and is fixed with the lower shell 3; if the inner side plate 5 has a problem, the outer side plate 6 is continuously pulled upwards, the elastic barbs deform to be separated from the hard barbs, and then the outer side plate 6 and the inner side plate 5 are manually dismantled for maintenance;

or after the inert gas is diluted, directly opening the cabinet door 4 and extracting the partition plate 7 of the part needing to be maintained through the pull ring and the connecting rod 702 for maintenance; if the upper partition plate 7 needs to be repaired, the lower partition plate 7 is firstly pulled out, then the telescopic piece 703 and the ladder 704 are stretched to be in contact with the ground, and the lower partition plate 7 is used as a ladder and a storage platform;

3. when the partition board 7 is not mounted on the guide rail 501, under the action of gravity, the outer side of the guide rail 501 drops, the guide rail 501 is in an open form, the wide end of the partition board 7 enters the guide rail 501, and then under the action of gravity of the partition board 7, the guide rail 501 is pressed down to drop the inner side of the guide rail 501, so that the partition board 7 automatically slides into the cabinet body 1; when the telescopic device 9 drives the outer side plate 6 to move up and down, the scraping brush 13 moves up and down in the vertical groove 602 and scrapes the filter screen 11, so that dust on the filter screen 11 is removed, and falls into the storage box 12;

4. when the moving wheel 104 rotates, the moving wheel 104 drives the lower end of the linkage rod 15 to rotate, and the upper end of the linkage rod 15 moves up and down in the vertical groove 602, so that the scraping brush 13 scrapes the filter screen 11 up and down, the dust on the filter screen 11 is removed, and the dust falls into the storage box 12.
