Abstract
The utility model relates to electric equipment field, relates in particular to a kind of distribution box.A kind of enclosed self is distribution box but, the casing that comprises sealing, the front of described casing, for cover plate is installed, is provided with semiconductor chilling plate group on the sidewall of described casing, the cold junction of described semiconductor chilling plate group is positioned at inside sidewalls, and the hot junction of semiconductor chilling plate group is positioned at sidewall outside.The utility model enclosed self but distribution box is cooling to carrying out in casing by semiconductor cooling piece group is set on sidewall, and this is cooling without ventilated, only at box house, the auxiliary convection circulation of fan is set and can realizes effective cooling; When both meeting distribution box sealing requirement, realized the demand of distribution box radiating and cooling, operating efficiency and the useful life of having improved electric component in distribution box.
Description
Technical field
The utility model relates to electric equipment field, relates in particular to a kind of distribution box.
Background technology
A total circuit distributor box of user power utilization.Distribution box by electrical wiring requirement by switchgear, measuring instrument, protection is electric and auxiliary equipment is assembled in sealing or semiclosed metal safe or screen width on, form power distribution equipment.During normal operation, can connect or minute deenergizing by manual or automatic switch.When fault or irregular operating by protection electric cut-out circuit or warning.Borrow measuring instrument can show operating various parameter, also can adjust some electric parameter, to departing from normal operating conditions, point out or send signal.Be usually used in each, join, in electric substation.
Because many electric components of settling in distribution box, when work, all can produce heat, so the temperature in distribution box tends to highlyer than ambient temperature, and high temperature can have influence on the performance of electric component, has influence on the useful life of electric component.Existing distribution box is divided into two kinds, semi-enclosed and closed, semi-enclosed radiator window, the radiator fans etc. of can arranging reduce the ambient temperature in distribution box, but its degree of protection is low, can only, for to power supply continuity and the lower industrial and mining enterprises of reliability requirement, be used as transformer room's centrally connected power supply.And enclosed distribution box is except installed surface, other all sides are all closed.The electric components such as the switch of this cupboard, protection and Monitoring and Controlling, are installed in a closure made from steel or insulating material, and barrier propterty is good, but heat-sinking capability is very poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide but distribution box of a kind of enclosed self, this distribution box is cooling to carrying out in casing by semiconductor cooling piece group is set on sidewall, this is cooling without ventilated, only at box house, the auxiliary convection circulation of fan is set and can realizes effective cooling; When both meeting distribution box sealing requirement, realized the demand of distribution box radiating and cooling, operating efficiency and the useful life of having improved electric component in distribution box.
The utility model is achieved in that but distribution box of a kind of enclosed self, the casing that comprises sealing, the front of described casing is for installing cover plate, on the sidewall of described casing, be provided with semiconductor chilling plate group, the cold junction of described semiconductor chilling plate group is positioned at inside sidewalls, and the hot junction of semiconductor chilling plate group is positioned at sidewall outside.
Fan is also housed in described casing.
Described installation cover plate is connected with casing by bearing pin, installs between cover plate and casing and is provided with sealing rubber ring.
On described installation cover plate, transparent window is housed.
The utility model enclosed self but distribution box is cooling to carrying out in casing by semiconductor cooling piece group is set on sidewall, and this is cooling without ventilated, only at box house, the auxiliary convection circulation of fan is set and can realizes effective cooling; When both meeting distribution box sealing requirement, realized the demand of distribution box radiating and cooling, operating efficiency and the useful life of having improved electric component in distribution box.
Accompanying drawing explanation
Fig. 1 is the but structural representation of distribution box of the utility model enclosed self.
In figure: 1 casing, 2 is installed cover plate, 3 semiconductor chilling plate groups, 4 fans, 5 bearing pins, 6 sealing rubber rings, 7 transparent windows.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, a kind of enclosed self is distribution box but, the casing 1 that comprises sealing, the front of described casing 1 is for installing cover plate 2, on the sidewall of described casing 1, be provided with semiconductor chilling plate group 3, the cold junction of described semiconductor chilling plate group 3 is positioned at inside sidewalls, the hot junction of semiconductor chilling plate group 3 is positioned at sidewall outside, the temperature difference of the cold and hot end of semiconductor chilling plate can reach between 40 ℃～65 ℃, by hot junction natural heat dissipation to external world, can guarantee that the ambient temperature in distribution box remains on 0 ℃～10 ℃ left and right, improved operating efficiency and the useful life of electric component in distribution box.
In order to strengthen the gas flow in casing, guarantee cooling efficiency and cooling uniformity, in described casing 1, fan 4 is also housed, by fan 4, make to produce in casing airflow circulating.
Convenient for switch, the installation cover plate 2 in the utility model is connected with casing 1 by bearing pin 5, installs between cover plate 2 and casing 1 and is provided with sealing rubber ring 6, to guarantee the sealing effect of casing 1; In addition, in order to observe easily the reading of instrument in distribution box, on described installation cover plate 2, transparent window 7 is housed.
Claims (4)
1. but distribution box of an enclosed self, the casing (1) that comprises sealing, the front of described casing (1) is for installing cover plate (2), it is characterized in that: on the sidewall of described casing (1), be provided with semiconductor chilling plate group (3), the cold junction of described semiconductor chilling plate group (3) is positioned at inside sidewalls, and the hot junction of semiconductor chilling plate group (3) is positioned at sidewall outside.
