This whole row of screen cabinet ventilation unit of relay protection room makes the ground part keep apart through the design of baffle, and the wind that the fan blew off can not carry the earth's surface dust and get into to the internal of cabinet to separate into through the baffle and form a relative inclosed cavity, make gaseous direct entering to the internal through the stainless steel mesh to the cabinet, discharge again by supreme flow down after getting into, the effectual heat dissipation that dispels, and carry dust volume contrast prior art and have the reduction, the practicality is higher.
Description
Technical Field
The utility model relates to a screen cabinet technical field specifically is a whole row of screen cabinet ventilation unit of relay protection room.
Background
The existing relay protection room whole-row screen cabinet is generally formed by connecting a plurality of screen cabinet monomers, the outermost side of the left side and the outermost side of the right side are provided with side screens, and the rest of the insides are communicated. For example, a whole row of screen cabinets of a substation of 110kV and below generally has about 8 screen cabinet units, while a whole row of screen cabinets of a substation of 220kV and above may be composed of more screen cabinet units. The ventilation design is not carried out in most of the devices, so that the heat generated by the devices in the devices cannot be dissipated, and the service life and the effective controllability of key parts are reduced due to the out-of-control temperature. Even some high-power equipment adopt the design of the monomer last blast of single screen cabinet occasionally, also only with fan seat direct mount in the free roof inboard of certain screen cabinet, only can realize the free ventilation of single screen cabinet, and its maintenance is extremely inconvenient, neither economy causes interior device deposition again easily, and it is big to transform the degree of difficulty after putting into operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a whole row of screen cabinet ventilation unit of relay protection room to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a whole row of screen cabinet ventilation unit of relay protection room, includes the screen cabinet body that constitutes by a plurality of screen cabinet monomers link to each other in proper order, two screen cabinet monomer lateral wall bottom rigid couplings in the screen cabinet body outside have the fan, screen cabinet body bottom rigid coupling has the stainless steel mesh, vacuole formation between stainless steel mesh and the ground, the fluting has been seted up to screen cabinet body bottom both sides, the cavity communicates with each other through the fluting, separate the chamber and separate the chamber down in the cavity through the baffle formation.
Preferably, the top of the front surface of the screen cabinet body is provided with an upper air outlet.
Preferably, the fans are arranged on two sides of the upper separation cavity.
Compared with the prior art, the beneficial effects of the utility model are that: this whole row of screen cabinet ventilation unit of relay protection room makes the ground part keep apart through the design of baffle, and the wind that the fan blew off can not carry the earth's surface dust and get into to the internal of cabinet to separate into through the baffle and form a relative inclosed cavity, make gaseous direct entering to the internal through the stainless steel mesh to the cabinet, discharge again by supreme flow down after getting into, the effectual heat dissipation that dispels, and carry dust volume contrast prior art and have the reduction, the practicality is higher.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is the bottom structure schematic diagram of the screen cabinet body of the present invention.
In the figure: 1. the screen cabinet comprises a screen cabinet body, a fan 2, a partition plate 3, an upper separation cavity 5, a lower separation cavity 6, a stainless steel net 7 and a groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a whole-row screen cabinet ventilation device of a relay protection chamber comprises a screen cabinet body 1 formed by sequentially connecting a plurality of screen cabinet monomers, wherein the bottom of the outer side walls of two screen cabinet monomers on the outermost side of the screen cabinet body 1 is fixedly connected with a fan 2, the model SF-138PZ02 of the fan is connected with an external power supply, the external power supply is 380V alternating current, the bottom of the screen cabinet body 1 is fixedly connected with a stainless steel mesh 6, the screen cabinet body 1 is communicated with an upper separation chamber 4 through meshes of the stainless steel mesh, a cavity is formed between the stainless steel mesh 6 and the ground, two sides of the bottom of the screen cabinet body 1 are provided with slots 7, the cavities are communicated with each other through the slots 7, an upper separation chamber 4 and a lower separation chamber 5 are formed in the cavity through a partition plate 3, the structural design of the upper separation chamber 4 and the lower separation chamber 5 is adopted, earth surface dust is separated in the lower separation chamber 5 through the partition, therefore the gaseous equipartition that the fan blew off enters into the screen cabinet in the bottom of every single screen cabinet in the mesh through stainless steel net 6, and gaseous insufflates the air exit through the top by the bottom and discharges, and fan 2 sets up in the both sides position that separates chamber 4 on, and the air exit has been seted up on the positive top of screen cabinet body 1.
The working principle is as follows: in the gas that the fan insufflates separates chamber 4 in insufflating, because last separate chamber 4 and be linked together through fluting 7, the gas equipartition that consequently the fan blew off enters into to the screen cabinet in the mesh through stainless steel net 6 in the bottom of every single screen cabinet, and gas is insufflated by the bottom and is discharged through the air exit at top.
In the description of the present invention, it is to be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "one side", "top", "inner", "front", "center", "both ends", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "disposed," "connected," "fixed," "screwed" and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
