The application provides a low-voltage cabinet of condensation of preventing, it includes that figure 1 and figure 2 show:
the low-voltage cabinet body 6 is arranged on the bottom frame E, and an air inlet plate adopting a stainless steel wire mesh is arranged at the bottom of the cabinet body;
a heat dissipation plate 5 attached and fixed to a top surface of the low-voltage cabinet body 6;
Wherein, can all set up to bolted connection between cooling panel 5, guide plate 2 and the 6 tops of low-voltage cabinet body, install low-voltage cabinet top heating panel between low-voltage cabinet body and low-voltage cabinet top guide plate. Therefore, when the box transformer station runs, cold air enters from the air inlet at the bottom of the low-voltage cabinet in a hollow arrow mode in the figure 1, so that hot air formed by the operation of the cabinet body is diffused from the top of the cabinet body through the heat dissipation plate to form circulation, and circulation is formed in the low-voltage cabinet. After the guide plate is installed, a smaller slope is formed outside the heat dissipation plate at the top of the cabinet body. When the roof produced the condensation and drip on the guide plate in the case becomes, because there is the angle of inclination in the guide plate, consequently, the condensation can directly flow to the low-voltage cabinet lateral surface along the slope and is discharged, can not influence the internal portion electrical component insulating properties of cabinet.
In the specific setting, referring to fig. 5, the bolts connecting the heat dissipation plate and the flow guide plate at the top of the cabinet body may be set to include two sets: a set of low side screws 7 and a set of high side screws 4. Two groups of bolts are respectively arranged at the left side and the right side of the top of the low-voltage cabinet body 6 and penetrate through fixing holes formed in corresponding positions on the heat dissipation plate 5 and the flow guide plate 2. The heat dissipation plate 5 and the top guide plate 6 are fixed through fixing holes with the same size, and the heat dissipation plate 5 and the top guide plate 2 are fixed through locknuts with the same diameter. In the specific setting, in order to ensure that the left side and the right side of the deflector have a height difference, one side of the high-side screw rod 4 of the deflector 2 can be connected with the deflector of the low-voltage cabinet by adopting an M10 multiplied by 80 screw rod, the height of the high-side screw rod 4 of the deflector is set to be higher than that of an M10 multiplied by 75 screw rod adopted by the low-side screw rod 7, and the height difference of 7-8 cm is formed between the deflector 2 and the heat dissipation plate 5. In order to connect and fix the top guide plate and the heat dissipation plate of the low-voltage cabinet, a limiting nut 3 and a locknut 1 are respectively fixed on the low-side screw 7 and the high-side screw 4. The limiting nut 3 is fixedly arranged at the bottom of the guide plate 2 and arranged between the guide plate 2 and the heat dissipation plate 5, and the installation height of the guide plate 2 is limited by the abutting of the top of the limiting nut and the bottom surface of the guide plate; locknut 1 is laminated in guide plate 2 top in order to fix guide plate 2. The heat dissipation plate 5 can be arranged parallel to the top of the low-voltage cabinet or directly attached to the top of the low-voltage cabinet and fixed through bolts. The heat dissipation plate 5 and the guide plate 2 form an included angle inclined to the left side of the top of the low-voltage cabinet through the installation height difference of 5mm between the two groups of screw rod upper limiting nuts 3 so as to provide guidance and drainage for water vapor condensation beads.
From this, after all parts installation, when the case becomes the indoor condensation that produces of low-pressure drop, guide plate 2 can be according to leading the condensation to the direction as shown in fig. 2, leads the condensation to the left side of low-voltage cabinet and drips. At this time, the side wall of the low-voltage cabinet body 6 is sealed, so that the liquid beads dropping from the side part can directly drop to the drainage sealing plate along the side wall of the low-voltage cabinet without affecting the electric elements in the cabinet body.
In other more specific implementation manners, the low-voltage cabinet may further set the diversion plate 2 thereof to a manner shown in fig. 6: the lower side of the guide plate 2 is set to be not provided with a folded edge, and the other three sides are respectively provided with a 15mm folded edge which is bent upwards. From this, the water conservancy diversion in-process, accessible hem restriction condensation water conservancy diversion direction makes the condensation can not follow other orientations and fall to the low-voltage cabinet surface, and only can fall to the bottom sealing plate in through left side low side drainage to the low-voltage cabinet left side.
For providing better radiating effect and stopping comdenstion water from heating panel top drippage to low-voltage cabinet, this application still can be through the mode shown in fig. 7, will heating panel 5 adopts dull and stereotyped preparation, sets up to the rectangle planking that has cooperation low-voltage cabinet top to dig hollow 2 mesh hollows of welding at the middle part of rectangle planking and be sealed by stainless wire net 8, stainless wire net 8's area is less than guide plate 2 areas. Therefore, the stainless steel wire mesh does not influence the air flow circulation interaction, the rectangular outer plate arranged on the periphery of the stainless steel wire mesh can further prevent condensate water around the guide plate from directly dripping to the top of the low-voltage cabinet, the condensate water can not drip into the low-voltage cabinet on the basis of meeting the internal thermal circulation ventilation of the low-voltage cabinet, and the insulation performance of internal elements of the low-voltage cabinet can be further guaranteed not to be reduced due to the influence of condensate liquid drops.
In order to ensure the circulation of the air flow inside the low-voltage cabinet, the present application may also use a manner similar to the above-mentioned heat dissipation plate to seal the bottom of the low-voltage cabinet body 6 with a bottom sealing plate 9 shown in fig. 8 and 9. The middle of the bottom plate 8 is also provided with a stainless steel mesh 8 to provide an air flow path, while the periphery of the bottom plate can also be provided with a rectangular frame to provide sufficient mounting strength and isolation. Seal improvement bottom air inlet area that can be further through stainless wire net respectively with low-voltage cabinet top, bottom, improve thermal cycle efficiency.
Cooperate in cabinet bottom structure, this application still can be further lay the end shrouding corresponding the periphery of bottom shrouding 9 positions on underframe E, will low-voltage cabinet body 6 is installed on the end shrouding through the structure that is shown in fig. 3, fig. 3 to the corresponding a set of hole that leaks that sets up in order to form the shown drainage shrouding structure of the shadow part of fig. 3 that is close to the position of water conservancy diversion contained angle bottom in the left end shrouding surface of low-voltage cabinet body 6. From this, this application can be through installing in the drainage shrouding and receiving the condensation of dripping by 2 contained angles bottom droppings of guide plate in the wash port that the low-voltage cabinet lateral part corresponds the low-voltage cabinet position of falling into water, with condensation drainage to drainage shrouding bottom, avoids 9 surface ponding of bottom shrouding.
