Abstract
The invention provides a switchboard capable of attaining cost reduction by reducing the number of ventilation fans, and also improving reliability. This switchboard comprises: a box body 1 having a plurality of unit chambers 4 partitioned therein and an aggregated duct 6 extending vertically; inverters 8 installed on the respective unit chambers 4; guide ducts 9 which are installed on the top of the unit chamber 4 and guides hot air from the inverter 8 to the aggregated duct 6; and a suction fan 11 which is installed on the outlet side of the aggregated duct 6 so as to exhaust collected hot air at the aggregated duct 6 to the outside of the box body 1.
Description
Technical field
The present invention relates to have the distribution board of scavenger fan, this scavenger fan has the hot gas that its heating is produced such as folding and unfolding in the intrinsic a plurality of converters of case forces to discharge to the case body exterior.
Background technology
In distribution board in the past, folding and unfolding is bigger in the caloric value of the intrinsic converter of case, hot gas entail dangers to converter itself that the heating of this converter produces and surrounding devices generation misoperation thereof, damage.In order to prevent this situation, have near scavenger fan is set respectively each converter, forces hot gas is discharged to the case body exterior by the action of each scavenger fan structure (such as, patent documentation 1: Japanese patent laid-open 10-210610 communique, Fig. 1).
In traditional distribution board, corresponding with each converter and be respectively equipped with ventilation fan, the platform number of ventilation fan increases, and the corresponding assembling operation time increases, and manufacturing cost increases simultaneously, exists also that the failure frequency that scavenger fan causes increases, the problem of reliability decrease.
The present invention is in order to address the above problem, and its purpose is to provide a kind of can cut down scavenger fan platform number, shortens the assembling operation time, and reduces manufacturing cost, improves the distribution board of reliability.
Summary of the invention
Distribution board of the present invention comprises: the case body, and it has the aggregation pipe that internal separation becomes a plurality of element cells and longitudinal extension; Be separately positioned on the heater in each element cell; Be arranged on the top of described element cell and will guide the conduit of described aggregation pipe into from the hot gas of each described heater; The described hot gas that is arranged on the outlet side or the inlet side of described aggregation pipe and will focuses in the described aggregation pipe is discharged to outside scavenger fan.
In distribution board of the present invention, by reducing the platform number of scavenger fan, can shorten the assembling operation time, and can reduce manufacturing cost, improve reliability.

Embodiment
Fig. 1 is the front view of the distribution board of the expression embodiment of the invention 1, Fig. 2 (a) is the front view of the distribution board inside of presentation graphs 1, Fig. 2 (b) is the cutaway view of expression along the A-A line of Fig. 2 (a), Fig. 3 is the front view of the conduit of presentation graphs 2, Fig. 4 is the right view of presentation graphs 3, and Fig. 5 is the left view of presentation graphs 3.
In this distribution board,, form interlayer by leaving a plurality of aspects 2 that are provided with at interval up and down in the inside of the case body 1 of case shape.Be respectively equipped with the side wall surface 3 that interlayer is divided into two at each interlayer, form element cell 4.In addition, portion within it, one-sided being formed with by the framework 5 to longitudinal extension of case body 1 divided the aggregation pipe 6 that forms.Be provided with rotating door 7 in the front of each element cell 4.Being respectively equipped with heater in each element cell 4 is converter 8.The cable of each converter 8 (not shown) stretches out to the outside of case body 1 by aggregation pipe 6.
Be provided with the conduit 9 that the end is connected with framework 5 on the top of each interlayer.The cross section of the conduit 9 of steel plate system is the コ font, has above towards aggregation pipe 6 acclivitous inclined planes 10.On the top of case body 1, the outlet side of aggregation pipe 6, being provided with scavenger fan is drawing fan 11.
In the distribution board of said structure, the hot gas that the heating of each converter 8 produces in each interlayer is being directed after rising element cell 4 in and along inclined plane 10 risings of each conduit 9, is guiding to aggregation pipe 6 shown in the arrow of Fig. 2 (a), Fig. 2 (b).In aggregation pipe 6, because of the action generation ascending air of drawing fan 11, therefore above-mentioned hot gas is discharged to the outside of case body 1 by this ascending air.
Thus, the action of 1 drawing fan 11 of the distribution board of present embodiment 1 by being arranged on aggregation pipe 6 outlet sides, the hot gas that each converter 8 can be produced is forced to discharge to the outside of case body 1, cut down the platform number of drawing fan 11, its result, can shorten the assembling operation time, reduce manufacturing cost simultaneously.
In addition, can reduce the failure frequency that drawing fan 11 causes, correspondingly can improve the reliability of distribution board.
In addition, in case body 1,, form a plurality of element cells 4 that form by side wall surface 3 divisions respectively at each interlayer owing to form interlayers by leaving a plurality of aspects 2 that are provided with at interval up and down, thus can reduce a large amount of converters 8 of folding and unfolding distribution board the space is set.
In addition, aggregation pipe 6 is separated with a plurality of element cells 4 by the framework 5 to longitudinal extension, and the cable of each converter 8 stretches out to same direction towards aggregation pipe 6, and each converter 8 can be made with same specification.
In addition, because the top formation of each conduit 9 is towards aggregation pipe 6 acclivitous inclined planes 10, the hot gas that each converter 8 heating produces successfully is drawn towards aggregation pipe 6, so can reduce the consumption of power of drawing fan 11.
In the foregoing description, as heater, converter is illustrated, but is not limited thereto.The present invention also is applicable to such as the distribution board with heaters such as semiconductor module for electric power, controllable silicon/diode group cover, reactors.
In addition, as scavenger fan,, also can drawing fan be set at the outlet end of aggregation pipe though the outlet side of the top of case body 1, aggregation pipe 6 is provided with drawing fan 11.
In addition, also can the pushing fan be set at bottom, the aggregation pipe inlet side of case body, the action by this pushing fan pushes the hot gas in the aggregation pipe, forces to discharge to the case body exterior, also the pushing fan can be set at the entrance point of aggregation pipe.
