Abstract
The present invention provides a kind of power distribution cabinet being beneficial to bus heat radiation；Including metal shell (1), there are inside metal shell at least three AC bus (2), described bus (2) is made up of copper pipe, is fixed on described metal shell, it is characterised in that: the surface of described bus can be provided with through hole (20)；Offering of described through hole meets following rule: the bus (2) of the bus from power distribution cabinet side to opposite side, and the quantity of described through hole (20) is gradually successively decreased or is incremented by.This kind of power distribution cabinet is so that bus region has good heat dispersion, and eliminates bus internal pressure, ensures the excellent electric conductivity energy of bus.
Description
Technical field
The present invention relates to power infrastructures field, especially, relate to a kind of power distribution cabinet.
Background technology
Power distribution cabinet is a kind of conventional power infrastructures, is a metal shell outside it, internal dress
Having substantial amounts of power components, operationally, inside has lasting big electric current, and therefore, caloric value is relatively
Greatly；Three AC bus the most therein, due to all electric currents in power distribution cabinet all by these three
Bus, therefore, its caloric value will be above other parts；But, in current power distribution cabinet, these three
AC bus generally uses hollow copper tubing to be made, though the heat of copper pipe surface can disperse, but copper
Owing to being sealing area inside pipe, the air of sealing will be heated continuously, heat up, and cause copper
The situation that pipe internal pressure is big, radiating effect is poor, limits the electric conductivity of bus.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of power distribution cabinet being beneficial to bus heat radiation,
This kind of power distribution cabinet is so that bus region has good heat dispersion, and eliminates inside bus
Pressure, ensures the excellent electric conductivity energy of bus.
The present invention solves technical problem and be the technical scheme is that this kind is beneficial to the distribution of bus heat radiation
Cabinet includes metal shell, has at least three AC bus inside metal shell, and described bus is by copper pipe
Make, be fixed on described metal shell, and the surface of described AC bus can be provided with through hole；Described
Offering of through hole meets following rule: the bus of the bus from power distribution cabinet side to opposite side, described logical
The quantity in hole is gradually successively decreased or is incremented by.
As preferably, described bus has the six roots of sensation altogether, wherein three be located at power distribution cabinet in top portion, with
The power components of top half in supply power distribution cabinet；Another three are arranged in power distribution cabinet portion on the lower, for
Answer the power components of the latter half in power distribution cabinet；The number of number of openings in three buses in described top portion
Amount increase and decrease order is contrary with number of openings increase and decrease order in three buses in described portion on the lower；So that
Good cross-ventilation can be formed between bus region and the bus region of lower section of top
Loop.
The beneficial effects of the present invention is: this power distribution cabinet operationally, in three buses arranged side by side due to
All having offered through hole, therefore, its internal heated gas will be discharged into outside, so that in bus
Portion's pressure significantly reduces, and makes bus internal heat discharge in a large number；Simultaneously as open in three buses
If number of openings gradually increasing or decreasing, this make each bus discharge steam during, discharge
Speed the most gradually increasing or decreasing so that the air pressure around three buses produces gradient difference, so that three
Root bus region forms windstream, this further improves the heat radiation of bus near zone.
Accompanying drawing explanation
Fig. 1 is embodiment one schematic diagram of the power distribution cabinet being originally beneficial to bus heat radiation.
Fig. 2 is embodiment two schematic diagram of the power distribution cabinet being originally beneficial to bus heat radiation.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Embodiment one:
In embodiment illustrated in fig. 1 one, this kind is beneficial to the power distribution cabinet of bus heat radiation and includes metal shell 1,
Metal shell 1 is internal has three AC bus 2, and described bus 2 is made up of copper pipe, is fixed on described
On metal shell 1, metal shell is stretched out by the insulated hole on rear wall in one end；The other end has wiring
Portion 3, the power components within connected with outer casing 1；The surface of described AC bus 2 can be provided with through hole 20；
Offering of described through hole 20 meets following rule: to right side on the left of the power distribution cabinet shown in Fig. 1, each always
The quantity of the through hole 20 on line is gradually successively decreased.
The power distribution cabinet that embodiment one relates to operationally, owing to all offering in three buses 2 arranged side by side
Through hole 20, therefore, its internal heated gas will be discharged into outside, so that the internal pressure of bus 2
Powerful width reduces, and makes bus internal heat discharge in a large number；Simultaneously as offer in three buses
Through hole 20 quantity is gradually successively decreased, this make each bus discharge steam during, mass rate of emission also by
Gradually successively decreasing, be embodied in, the hot air discharge amount of left side bus is maximum, and middle bus is secondly, right
The hot air discharge amount of side bus is minimum, and so, the air pressure around three buses will produce gradient difference, from
And making three bus regions form windstream, as shown by the arrows in Figure 1, this is further in direction
Promote the heat radiation of bus near zone；This kind of power distribution cabinet is so that bus region has well
Heat dispersion, and eliminate bus internal pressure, ensure the excellent electric conductivity energy of bus.
Embodiment two:
Fig. 2 show embodiments of the invention two, and wherein, described bus 2 has the six roots of sensation altogether, wherein
Three be located at power distribution cabinet in top portion, to supply the power components of top half in power distribution cabinet；Another three
It is arranged in power distribution cabinet portion on the lower, to supply the power components of the latter half in power distribution cabinet；Described top
In three buses in portion, the quantity of through hole 20 is the most gradually successively decreased, logical in three buses in portion on the lower
The quantity in hole 20 is the most gradually incremented by, and this makes the bus region bus with lower section of top
Can form good cross-ventilation loop between region, anticipate as shown by the arrows in Figure 2, this is again
Improve the heat dispersion within whole electric power cabinet largely, not only make the internal heat of electric power cabinet
Amount uniformly, and in air flow process, accelerates the external loss of heat.
The foregoing is only the preferred mode of the present invention, not in order to limit the present invention, all in the present invention
Spirit and principle within, any modification, equivalent substitution and improvement etc. made, should be included in this
Within the protection domain of invention.
