Abstract
The utility model discloses an electric control cabinet, which includes a cabinet body and a cabinet door, and is characterized in that heat-dissipation slotted holes are formed at the upper and the lower ends of the cabinet body or the cabinet door, and filter nets are arranged at the heat-dissipation slotted hole parts on the cabinet body or the cabinet door. The upper heat-dissipation slotted hole is formed on a top plate of the cabinet body, and a cover plate slightly larger than each heat-dissipation slotted hole and higher the upper heat-dissipation slotted hole. Fans are arranged at the upper and the lower heat-dissipation slotted holes. The electric control cabinet with the upper and the lower heat-dissipation holes, which adopts the structure, has the advantages as follows: when electrical appliance components in the cabinet body are heated, heat increases and is excluded through the heat-dissipation slotted holes, cold air is continuously supplied to the cabinet through the lower heat-dissipation slotted holes, and a natural air duct is formed in the cabinet body from bottom to top to achieve the heat-dissipation purpose; the filter nets are arranged on the heat-dissipation holes to prevent sundries from entering the cabinet during the ventilation; and the cover plate is arranged on the upper heat-dissipation slotted hole on the top plate of the cabinet body to further protect the heat-dissipation slotted holes.
Description
Technical field
The utility model relates to a kind of electric control cabinet, and particularly a kind of heat radiation is electric control cabinet preferably.
Background technology
In electric control cabinet, a large amount of appliance components have in use produced a large amount of heats.Because the use of appliance component, temperature to environment for use all has certain requirement, if the electric control cabinet temperature inside is higher, will produce a lot of unnecessary problems to the use of appliance component, as, the components and parts precision is not enough, equipment fault or the like, and these all affect to safe, the stable operation of electric power system.For example in electric control cabinet, electric capacity etc. have produced a large amount of heats, and often be installed in voltameter in the electric control cabinet, its AD converting unit of measuring electric weight just has certain dependence to ambient temperature, only in certain temperature range, its precision is only accurately, if if variety of problems will certainly appear in untimely the leaving of heat that produces.
Present widely used electric control cabinet all is provided with aperture on its surface and dispels the heat, and it is improper that the position of aperture is provided with, and does not reach heat radiation, falls the effect of appearance; In addition, aperture does not reach the purpose of heat radiation if setting is too little; The aperture setting is too big, and toy is unfavorable to the operation of electric power system as if creeping into electric control cabinet.
The utility model content
Technical problem to be solved in the utility model just provides a kind of electric control cabinet, and it can leave the heat in the electric control cabinet effectively.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electric control cabinet, comprise cabinet and cabinet door, and it is characterized in that: described cabinet or cabinet door upper/lower terminal are provided with the heat radiation slotted eye, on cabinet or cabinet door, heat radiation slotted eye place is provided with filter screen.
As improvement of the present utility model, the described heat radiation slotted eye of going up is arranged on the top board of cabinet, and this slotted eye is more a little bit smaller than top board, and same, slotted eye goes out to be provided with filter screen.Have above the slotted eye on the ratio heat radiation slotted eye bigger and exceed on the cover plate of heat radiation slotted eye.Slotted eye dispel the heat on this owing to very big, and be horizontal positioned, animal or other objects of mouse and so on enter so for example be easy to, and the cover plate of its top can protect last heat radiation slotted eye.
Further improve as of the present utility model, the filter screen that described heat radiation slotted eye place is provided with is a sponge.
Adopt the electric control cabinet of the upper and lower heat radiation slotted eye of said structure, after the heating of the electric elements in the cabinet, heat rises, get rid of by last heat radiation slotted eye, and cold air constantly by under the slotted eye that dispels the heat replenish into cabinet, cabinet reaches the heat radiation purpose by forming the nature air channel from bottom to top, can effectively heat in the electric control cabinet be got rid of.Filter screen is set above the louvre, can when ventilating, prevents that foreign material from entering in the cabinet.And the slotted eye that dispels the heat on the cabinet top board, the cover plate that it is provided with above can further protect louvre.
Description of drawings
Fig. 1 is the structural representation of electric control cabinet of the present utility model;
Fig. 2 is the structural representation of another execution mode of heat radiation slotted eye on the electric control cabinet of the present utility model;
Fig. 3 is the vertical view of another execution mode of heat radiation slotted eye on the electric control cabinet of the present utility model;
Fig. 4 is a heat radiation slotted eye schematic diagram on the electric control cabinet of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further details.
By physics general knowledge as can be known, cold air is because density is big, and its travel direction is from top to bottom, and hot-air is because density is little, and its travel direction is just in time opposite with cold air.So the louvre above the electric control cabinet need design, allow hot-air can flow out cold air as soon as possible and then enter electric control cabinet fast.
As shown in Figure 1, a kind of electric control cabinet comprises cabinet 1 and cabinet door 2, it is characterized in that: described cabinet 1 or cabinet door 2 upper/lower terminals are provided with heat radiation slotted eye 3, the slotted eye 4 that dispels the heat down.
In the electric power system, be very high to safe requirement, enter in the electric control cabinet in order to prevent external article, for example prevent that mouse from entering control cubicle and causing short circuit accident, on cabinet 1 or cabinet door 2, heat radiation slotted eye place is provided with filter screen 7 as shown in Figure 3.Certainly, the filter screen of small-bore also can filter dust.
As improvement, as shown in Figure 2, on the slotted eye 3 that dispels the heat be arranged on the top board 5 of cabinet 1, have above the last heat radiation slotted eye 3 heat radiation slotted eye on the ratio 3 bigger and exceed on the cover plate 6 of heat radiation slotted eye 3.Like this, even rainwater is arranged, the upward heat radiation slotted eye of described level also can not suffer the destruction of rainwater, can also prevent that dust from entering in the cabinet.
In the summer of sweltering heat, indoor temperature is very high, the working range that often exceeds components and parts at indoor electric control cabinet internal temperature, closed cabinet inside is particularly serious, the gas temperature that its slotted eye that dispels the heat down enters in the cabinet is also very high, heat in this cabinet can shed as early as possible, accelerates the circulation of cabinet inner air.
Certainly, the technical solution of the utility model not only can be embodied in above the electric control cabinet, and box-type substation also can adopt this technical scheme to solve the heat dissipation problem of enclosed box-type substation.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection range of the present utility model.
