Description

Technical Field

[0001] The invention relates to the technical field of switch cabinets, and in particular to a drawer-type switch cabinet device for power transmission and transformation. Background Art

[0002] The drawer-type switch cabinet is a closed shell made of steel plates. The electrical components of the incoming and outgoing line circuits are installed in the drawer, forming a functional unit that can complete a certain type of power supply task. The functional unit of the drawer-type switch cabinet is separated from the busbar or cable by a grounded metal plate or a functional board made of plastic, forming three areas of the busbar, functional unit and cable. There are also isolation measures between each functional unit. The drawer-type switch cabinet has high reliability, safety and interchangeability. It is a relatively advanced switch cabinet. Most of the switch cabinets produced are drawer-type switch cabinets. They are suitable for industrial and mining enterprises and high-rise buildings that require high power supply reliability as a centralized control distribution center.

[0003] In specific applications, drawer cabinets are generally placed indoors and use air conditioning and other measures to achieve uniform temperature regulation. However, in actual use, due to the limitations of cooling measures such as air conditioning, the indoor temperature regulation is not uniform. On the side far away from the air conditioner, the temperature of the switch cabinet cannot be reduced quickly. At the same time, since the switch cabinet is relatively closed, the internal temperature is easy to rise, which in turn causes high-temperature burning inside, posing a safety hazard. At the same time, the switch cabinet does not have any dust-proof measures when in use, which also causes a large amount of dust to accumulate on the electrical equipment in the drawer cabinet. Over time, it is also easy to cause damage to the equipment, which in turn causes a series of secondary problems. Summary of the invention

[0029] In the present invention, by setting up the ventilation and heat dissipation device, when the drawer cabinet is in use, the blower is connected to the air outlet position of the air conditioner. At this time, the air of the air conditioner enters the air inlet pipe through the transfer box, and then enters the multiple ventilation hoods, and then enters the drawer cabinet through the multiple heat dissipation holes, thereby taking away the hot air in the drawer cabinet. At this time, the exhausted air is discharged through the air outlet pipe to realize ventilation and heat dissipation of the drawer cabinet, and in the whole heat dissipation process, it is in a sealed state, so it will not cause the problem of dust accumulation, and effectively avoid the problem of overheating and damage of electrical equipment in the drawer cabinet due to dust accumulation; in addition, the incoming air is dried by the desiccant in the drying box, effectively avoiding the problem of excessive moisture in the air causing damage to electrical equipment due to moisture, thereby ensuring the continuous normal operation of the switch cabinet.

[0030] Furthermore, in the present invention, by setting an active pop-up device, when the plug on the drawer cabinet and the connector strip on the switch cabinet body cause problems such as arc sparking or fire due to poor contact or other reasons, the clamping frame becomes soft or even melted due to heat, and the drawer cabinet loses its pulling force. Under the pull of the two ejection springs, the drawer cabinet is pulled out of the switch cabinet body, and the passive push plate is blocked by the baffle plate, so that the passive push plate moves in the movable hole, and at the same time drives the reset spring to be stressed. At this time, the passive push plate drives the inner closing frame to move, and then the inner closing frame blocks and closes the multiple heat dissipation holes in the drawer cabinet. At this time, the drawer cabinet can be sealed to prevent the fire from extending into the electrical equipment, thereby ensuring the safety of the electrical equipment. At the same time, it can also avoid continuous blowing to cause internal fire or fire expansion.

[0031] Furthermore, in the present invention, by setting a blocking fire extinguishing device, when the drawer cabinet is pushed out, the wedge block no longer squeezes the return frame. At this time, under the return force of the return spring, the return spring pulls the return frame upward, so that the return frame drives the blocking box to block and seal the plug-in strip, thereby preventing the plug-in strip from being exposed to rust for a long time. If a fire occurs and the drawer cabinet is pushed out, the temperature of the plug-in strip will burn the sealing sleeve. At this time, the fire extinguishing sand in the blocking box will flow out, thereby realizing active and rapid fire extinguishing, effectively ensuring the safe use of the switch cabinet.

At this time, under the return force of the return spring 704, the return spring 704 pulls the return frame 702 upward, realizing the automatic reset of the return frame 702, and then realizing the automatic blocking of the blocking box 701.

[0066] In summary, the working principle of a drawer-type switch cabinet device for power transmission and transformation provided by an embodiment of the present invention is:

[0067] When the drawer cabinet 2 is in use, the blower 504 is connected to the air outlet position of the air conditioner. At this time, the air from the air conditioner enters the air inlet pipe 502 through the transfer box 505, and then enters the multiple ventilation hoods 501, and then enters the drawer cabinet 2 through the multiple heat dissipation holes 607, thereby taking away the hot air in the drawer cabinet 2. At this time, the exhausted air is discharged through the air outlet pipe 503, thereby realizing ventilation and heat dissipation of the drawer cabinet 2, and in the entire heat dissipation process, it is in a sealed state, so there is no problem of dust accumulation, and the problem of overheating and damage of the electrical equipment 8 in the drawer cabinet 2 due to dust accumulation is effectively avoided; in addition, the incoming air is dried by the desiccant in the drying box 506, effectively avoiding the problem of excessive moisture in the air causing damage to the electrical equipment 8 due to moisture, and at the same time, the filter The setting of the net 507 further filters the dust, and when the blower 504 is started, a driving shaft 511 is driven to rotate through the rotating shaft, so that the driving shaft 511 drives the belt 513 to rotate through the pulley 512, and then the belt 513 drives another driving shaft 511 to rotate through another pulley 512. At this time, the driving shaft 511 drives the rotating column 510 to rotate, and the rotating column 510 drives the extrusion block 514 to move through the extrusion groove 515, so that the extrusion block 514 drives the cleaning frame 508 to move, and when the rotating column 510 continues to rotate, as the opening of the extrusion groove 515 changes, the extrusion block 514 is driven to reciprocate, and then the cleaning frame 508 is driven to reciprocate, so as to clean the filter net 507, and further avoid the problem of dust accumulation;

[0068] Further, when the plug 4 on the drawer cabinet 2 and the plug strip 3 on the switch cabinet body 1 cause arc sparking or fire problems due to poor contact or other reasons, the clamping frame 602 is heated to soften or even melt, and the drawer cabinet 2 loses its pulling force. Under the pulling of the two ejection springs 606, the drawer cabinet 2 is pulled out of the switch cabinet body 1, and the passive push plate 609 is blocked by the baffle 613, so that the passive push plate 609 moves in the movable hole 612, and the reset spring 610 is driven to be stressed. At this time, the passive push plate 609 drives the inner sealing frame 608 to move, so that the inner sealing frame 608 blocks and seals the multiple heat dissipation holes 607 in the drawer cabinet 2. At this time, the drawer cabinet 2 can be sealed to prevent the fire from extending into the electrical equipment 8, thereby ensuring the safety of the electrical equipment 8, and at the same time, it can also avoid the problem of internal fire or fire expansion caused by continuous blowing;

[0069] Furthermore, when the drawer cabinet 2 is pushed out, the wedge block 705 no longer squeezes the return frame 702. At this time, under the return force of the return spring 704, the return spring 704 pulls the return frame 702 upward, and then the return frame 702 drives the blocking box 701 to block and seal the plug-in strip 3, thereby preventing the plug-in strip 3 from being exposed for a long time and rusting. In addition, if a fire occurs and the drawer cabinet 2 is pushed out, the temperature of the plug-in strip 3 will burn the sealing sleeve 706. At this time, the fire extinguishing sand in the blocking box 701 will flow out, realizing active and rapid fire extinguishing, thereby effectively ensuring the safe use of the switch cabinet 1.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
