Description
Technical field
The present invention relates to a kind of power distribution cabinet, be specifically related to the power distribution cabinet with good water resistance, belong to electrical equipment technical field.
Background technology
Power distribution cabinet sub-power power distribution cabinet and light distribution cabinet are the final stage device of distribution system.Power distribution cabinet is often unavoidably subject to the invasion and attack of water, if water instills from the plan vertical of power distribution cabinet or tilts to enter power distribution cabinet inside, the element of power distribution cabinet will be soaked in water, thus cause electric equipment short circuit normally to run.Instilling or instillation of tilting from the plan vertical of power distribution cabinet to solve rainwater, in prior art, the whole body of power distribution cabinet being designed to hermetically-sealed construction, although to some extent solve the waterproof problem of power distribution cabinet, but ignoring the heat dissipation problem of power distribution cabinet.Also have a very scabrous problem to be: work as rainstorm weather, the ponding on ground is a lot, enter into the inside of power distribution cabinet easily via the ventilating heat dissipating hole of power distribution cabinet or cabinet door gap, cause the short circuit of power distribution cabinet inside.
Summary of the invention
The technical problem to be solved in the present invention is: when rainstorm weather arrives, excess surface water is a lot, and ponding easily enters into power distribution cabinet inside by the cabinet crack between a door and its frame gap of power distribution cabinet or ventilating heat dissipating hole.
In order to realize solving above technical problem, the technical solution adopted in the present invention is: the power distribution cabinet with good water resistance, comprises cabinet, and cabinet front portion arranges cabinet door; Cabinet inside arranges multiple lateral partitions being parallel to cabinet floor, forms chamber between lateral partitions and lateral partitions; Cabinet inside arranges two longitudinal baffles, and longitudinal baffle is all perpendicular to cabinet floor, and two longitudinal baffles form air channel, and longitudinal baffle is communicated with described chamber; The rear portion of cabinet is provided with air inlet, and blower fan is arranged at cabinet inside, by the air channel described in the air intake outside cabinet;
Also comprise circle to keep off the rain ceiling, barrel-shaped water-tight device;
Cabinet is arranged at the centre of barrel-shaped water-tight device, and the circle ceiling that keeps off the rain is arranged at the top of cabinet;
The circle ceiling that keeps off the rain covers the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground;
Distance between the cabinet door of described cabinet and the side of barrel-shaped water-tight device is all greater than the width of cabinet door;
Bottom surface and the side of described barrel-shaped water-tight device all have water resistance;
The bottom surface of described barrel-shaped water-tight device is parallel to ground.
Further, the scheme be more preferably, the cabinet door of described cabinet is provided with louvre.
Further, the scheme be more preferably, described air inlet is provided with screen pack.
Further, the scheme be more preferably, described louvre is provided with the outward extending cover edge that keeps off the rain.
Further, the scheme be more preferably, left surface and the right flank of described cabinet are provided with louvre.
Further, the scheme be more preferably, described louvre is provided with the outward extending cover edge that keeps off the rain.
Compared with prior art, the invention has the advantages that: the first, the power distribution cabinet with good water resistance provided by the invention, when rainstorm weather arrives, when excess surface water is a lot, also can not enter into power distribution cabinet inside by the cabinet crack between a door and its frame gap of power distribution cabinet or ventilating heat dissipating hole; Second, traditional power distribution cabinet considers necessity of waterproof, the louvre of power distribution cabinet is not a lot, due to the structure that the present invention is special, excess surface water can not enter into the inside of power distribution cabinet, therefore the present invention can arrange more louvre, is more conducive to the heat radiation of power distribution cabinet internal circuit, extends the useful life of power distribution cabinet electric equipment.3rd, the circle ceiling that keeps off the rain covers the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground, thus ensures that rainwater that sky falls can not drop into the inside of barrel-shaped water-tight device; Distance between the cabinet door of cabinet and the side of barrel-shaped water-tight device is all greater than the width of cabinet door, thus ensures that cabinet door can normally be opened.

Fig. 3 is overhead view schematic diagram of the present invention.
Wherein, 1 is cabinet, and 2 is chambers, and 31 is lateral partitions, and 4 is electric equipments, and 5 is cabinet doors, and 6 is air inlets, and 7 is blower fans, and 32 is longitudinal baffles, and 8 is cabinets, and 9 is barrel-shaped water-tight devices, and 10 is that circle is kept off the rain ceiling.
Embodiment
Below in conjunction with accompanying drawing, invention is described in further detail.
As shown in Figure 1, 2, 3, have the power distribution cabinet of good water resistance, comprise cabinet, cabinet front portion arranges cabinet door; Cabinet inside arranges multiple lateral partitions being parallel to cabinet floor, forms chamber between lateral partitions and lateral partitions; Cabinet inside arranges two longitudinal baffles, and longitudinal baffle is all perpendicular to cabinet floor, and two longitudinal baffles form air channel, and longitudinal baffle is communicated with described chamber; The rear portion of cabinet is provided with air inlet, and blower fan is arranged at cabinet inside, by the air channel described in the air intake outside cabinet;
Also comprise circle to keep off the rain ceiling, barrel-shaped water-tight device; Cabinet is arranged at the centre of barrel-shaped water-tight device, and the circle ceiling that keeps off the rain is arranged at the top of cabinet;
The circle ceiling that keeps off the rain covers the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground; Distance between the cabinet door of described cabinet and the side of barrel-shaped water-tight device is all greater than the width of cabinet door; Bottom surface and the side of described barrel-shaped water-tight device all have water resistance; The bottom surface of described barrel-shaped water-tight device is parallel to ground.
Further, the scheme be more preferably, left surface and the right flank of described cabinet are provided with louvre, and the cabinet door of described cabinet is provided with louvre.
Wherein, described air inlet is provided with screen pack.
Wherein, described louvre is provided with the outward extending cover edge that keeps off the rain.
The principle of the invention illustrates: the ponding on ground and cabinet completely cut off by barrel-shaped water-tight device to be opened, even if so rainstorm weather excess surface water also can not enter into cabinet inside; The circular ceiling that keeps off the rain effectively prevents the aerial rainwater in sky from entering cabinet simultaneously, because the circle ceiling that keeps off the rain covers the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground, it aerial rainwater also can not enter into the inside of barrel-shaped water-tight device, therefore cabinet is positioned in the middle of barrel-shaped water-tight device very safe, does not have any rainwater and enters.It is emphasized that the distance between the cabinet door of cabinet and the side of barrel-shaped water-tight device is all greater than the width of cabinet door, only in this way the cabinet door of guarantee power distribution cabinet can normally be opened smoothly.Also have the circular ceiling that keeps off the rain to cover the projection of barrel-shaped water-tight device perpendicular to ground perpendicular to the projection on ground, the rainwater that only in this way guarantee sky falls can not enter the inside of barrel-shaped water-tight device.
