It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

As shown in fig. 1, the present invention provides a frequency conversion distribution room building to solve the technical problems of poor ventilation of the frequency conversion distribution room and overheating of the power unit of the frequency converter in the prior art. The variable frequency electric distribution room includes an electric distribution room body 100 and a door 200, and the structure of the electric distribution room body 100 and the structure of the door 200 will be described in detail below.

As shown in fig. 1 and 2, the electricity distribution room body 100 is a building having an internal cavity, and is built on an outdoor space, and includes an outer wall of the electricity distribution room and a roof of the electricity distribution room mounted on the top of the outer wall of the electricity distribution room. The electricity distribution room body 100 may be a steel structure building or a brick structure building. The inside of the electricity distribution room body 100 is used for placing the frequency conversion cabinet. An access for equipment and personnel to enter and exit is provided on the outer wall of the electricity distribution room at one side of the electricity distribution room body 100.

As shown in fig. 2 and 3, the door 200 is installed at an entrance of the electricity distribution room body 100, an outer wall where the entrance of the electricity distribution room is located is used as a wall, the door 200 is constructed by installing the outer wall of the door 200 and a roof of the door 200, and an indoor space for people to move is formed inside the door 200. The doorways 200 have an outer door 210 and an inner door 220, wherein the inner door 220 is installed at an entrance of the electricity distribution room body 100, the outer door 210 is installed on a wall of the doorways 200, and the inner door 220 and the outer door 210 are oppositely disposed. The external door 210 can move to and from the outside of the building and the inside of the doorsill 200, and the internal door 220 can move to and from the inside of the doorsill 200 and the inside of the electricity distribution room body 100. The outer door 210 and the inner door 220 are both outward-opening door bodies. Install the first louver 211 outside the intercommunication and inside the door hopper 200 on the door body of outer door 210, the grid of first louver 211 sets up down, can enough realize taking a breath, can prevent again that rainwater and bold impurity from getting into in the door hopper 200 through first louver 211. Install the inside first filter screen 221 with the electricity distribution room body 100 inside of intercommunication door fill 200 on the door body of interior door 220, first filter screen 221 is arranged in filtering the small-size impurity in the air that gets into the electricity distribution room by door fill 200, for example dust, iron fillings etc. have an effect to the impurity of converter normal operating in the air. The first filter 221 may have a single-layer structure, or may have a multi-layer structure in which a plurality of first filters 221 are stacked. The first filter 221 has a single-layer structure or a multi-layer structure, and is disposed according to the size of the impurities or dust to be filtered and the mesh number of the first filter 221. The first filter screen 221 is detachably connected with the door body of the inner door 220, so that the first filter screen 221 can be replaced regularly, and the filtering effect of the first filter screen 221 is ensured. Specifically, the first filter screen 221 may be fixed to the door body of the inner door 220 in a bolt connection or a mortise and tenon connection manner.

As shown in fig. 2 and 3, the outer door 210 is a safety door meeting the requirement of the power distribution chamber door body, the inner door 220 is a double door which is opened outwards, the number of the double doors may be one or two, and when the number of the double doors is two, the two double doors are arranged at intervals along the horizontal direction. Two first filter screens 221 are all installed to every door leaf of two opening doors of interior door 220, and two first filter screens 221 on the same door leaf set up along vertical direction interval to the air input of increase door leaf.

As shown in fig. 2 and 3, a sealing strip is attached to an edge of the door body of the inner door 220, and the sealing strip can fill a gap between the door body and the door 200 and a gap between the door leaves, thereby preventing impurities from entering the interior of the distribution room body 100 through the gaps.

As shown in fig. 2 and 3, by additionally providing the door 200 at the entrance of the electricity distribution room main body 100, when a person needs to enter the electricity distribution room main body 100, the person needs to open the outer door 210 of the door 200 first to enter the door 200, then close the outer door 210, then open the inner door 220, and finally enter the electricity distribution room main body 100. Therefore, impurities which have influences on the normal operation of the frequency conversion chamber cannot directly enter the interior of the distribution chamber body 100 when the door is opened, but enter the door hopper 200. And install first shutter 211 on the outer door 210 of door fill 200, install first filter screen 221 on the inner door 220 of door fill 200, compare in the totally closed door body of current frequency conversion electricity distribution room, can effectively increase the inside and external air flow of electricity distribution room body 100, solve the serious problem of the inside negative pressure of electricity distribution room. Meanwhile, the first louver 211 can block large impurities and rainwater from entering the door 200, and a small amount of small impurities entering the door 200 through the first louver 211 can be blocked by the first filter 221 installed on the inner door 220 and cannot enter the interior of the distribution room body 100. In addition, the inner space of the door 200 may also play a certain role in buffering small impurities entering the door 200, and some impurities may fall on the ground of the door 200 due to gravity. The regular replacement of the first filter 221 can ensure the effect of filtering the intake air.

As shown in fig. 2 and 3, in order to increase the air intake amount of the power distribution room body 100 and improve the negative pressure state inside the power distribution room body 100, a window hole communicating with the outside is formed in a side wall of the door 200, where the side wall is a side wall connecting a wall where the outer door 210 is located and a wall where the inner door 220 is located. The window hole is provided with a second filter screen 240 and a second louver 230. The edge of the second filter 240 is hermetically connected to the window hole, and the edge of the second louver 230 is hermetically connected to the window hole. And, second shutter 230 is located the outside of second filter screen 240, and second shutter 230 is located the window opening and is close to the outside one end promptly, and second filter screen 240 is located the window opening and is close to the inside one end of door fill 200, like this, blocks large-scale impurity and rainwater through second shutter 230, realizes coarse filtration, and second filter screen 240 blocks small-size impurity, realizes the fine filtration. The amount of air intake of the door 200 can be increased by providing the second louver 230 and the second filter 240, and accordingly, the amount of air intake inside the electric distribution room is also increased. The second filter 240 has a single-layer structure or a multi-layer structure, and is disposed according to the size of the impurities or dust to be filtered and the mesh number of the second filter 240. The second filter 240 is detachably coupled to a side wall of the door 200 so that the second filter 240 can be periodically replaced.
