A kind of distribution box
Technical field
The utility model relates to power equipment, specifically, relates to a kind of distribution box.
Background technology
In the prior art, distribution box is a casing of being furnished with chamber door, generally is installed in the open air.Because distribution box inside is integrated with electric elements module and the various discrete electronic devices and components of more much caloric values usually, these electric elements are worked in hot environment for a long time, not only can premature aging, reduction of service life, and, in case the distribution box internal temperature is too high, will have a strong impact on control precision and control stability, even cause electric elements to burn, cause unexpected the shut-down, especially switch trip phenomenon in the distribution box can frequently occur season at summer high temperature, affect power supply reliability.
Summary of the invention
The technical problems to be solved in the utility model is to overcome defects, and a kind of have rain and sun, automatic heat radiation cooling function are provided, and can guarantee the electric elements distribution box in useful life.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of distribution box comprises the casing of being furnished with chamber door, it is characterized in that: the top of described casing is provided with lambdoid rain-proof sun shade; The top of casing left and right sides sidewall is fixed with respectively left support arm, right support arm, vertically is fixed with left pillar on the left support arm, vertically is fixed with right pillar on the right support arm; Described rain-proof sun shade is fixed on left pillar and the right pillar; Be provided with radiator fan between the top of rain-proof sun shade and casing No. one, the top board of casing is provided with louvre; Be provided with intelligence controlling device and temperature sensor in the casing, temperature sensor and a radiator fan are connected on the intelligence controlling device.
Say that further the bottom of described casing is fixed with the base of hollow, be provided with radiator fan in the cavity of base No. two, the base plate of casing is provided with air-vent; Base is provided with some ventilation holes; No. two radiator fan is connected on the intelligence controlling device.
Furtherly, the chamber door of described casing is provided with the air vent hole of some strips.
Owing to adopted technique scheme, compared with prior art, the utility model can play by rain-proof sun shade the effect of rain and sun to distribution box and inner electric elements thereof; By temperature sensor monitors distribution box internal temperature, and control radiator fan at top and No. two radiator fans of bottom by intelligence controlling device, in time give the distribution box radiating and cooling, to guarantee the useful life of electric elements.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
