Abstract
The utility model relates to an intelligent outdoor temperature-constant and humidity-constant substation cabinet. The cabinet comprises a cabinet body (1) and a door (2), wherein the cabinet body and the door form an enclosed electric component installing space (3). Each of side plates, a bottom plate and a top plate of the cabinet body and the door is formed by welding two layers of steel plates, wherein a heat-preservation and heat-insulation asbestos layer (4) is filled between the steel plates, and a minute-surface aluminum film is plastered on the surface of an inner steel plate. An indoor air-conditioning set (5) is installed in the enclosed electric component installing space (3), and an outdoor air-conditioning set (6) is fixed on the external surface of a cabinet side or the external surface of the door, wherein the indoor air-conditioning set (5) and the outdoor air-conditioning set (6) are connected by refrigerant pipelines and electrical control lines (7). When the intelligent outdoor temperature-constant and humidity-constant substation cabinet is installed locally, it is avoided that electronic components are damaged by temperature and humidity environments, it is ensured that automatic safety devices are operated normally.
Description
Technical field
The utility model relates to a kind of transformer station power distribution cabinet, specifically the outdoor thermo-humidistat cabinet of a kind of intelligent substation.
Background technology
Intelligent substation/cabinet is that various electric elements, intelligent assembly and protective device are assembled in a space or the casing; generally be installed in the open air; because being electronic devices and components, intelligent assembly and protective device form; install on the spot; temperature and humidity environment are very large on its impact; may cause components and parts to damage, cause protection and automatic safety device malfunction or tripping.
On October 7th, 2009, Chinese utility model patent Granted publication CN 201323418Y, disclose a kind of from cooling distribution box, refrigeration and heat radiator is installed at top at distribution box, this refrigeration and heat radiator comprises the hot junction aerofoil fan, semiconductor refrigerating module and cold junction aerofoil fan are installed successively from top to bottom, although this patent has proposed a kind of semiconductor refrigerating module cooling measure, but because the characteristic of semiconductor refrigerating module, the hot junction of semiconductor refrigerating module and the temperature difference of cold junction can not be excessive, when the temperature difference surpasses 40 ℃, its Energy Efficiency Ratio will be less than 1, that is to say, when ambient temperature was higher, such as the summer of sweltering heat, this refrigeration and heat radiator but refrigerating capacity became worse and worse.Exactly during this time live load is maximum and for the electric equipment in the distribution box body of realizing goal of the invention, element, more need cooling, therefore, this structure easily impacts the safe operation of power equipment, so be not suitable for extensive use in power equipment.
The utility model content
The purpose of this utility model provides the outdoor thermo-humidistat cabinet of a kind of intelligent substation; in the time of can guaranteeing to install on the spot; temperature humidity satisfies the requirement of electronic devices and components humiture, and the damage of avoiding electronic devices and components to cause because of the humiture environment guarantees that protection and automatic safety device normally move.
The technical solution of the utility model is achieved in that
The outdoor thermo-humidistat cabinet of a kind of intelligent substation comprises cabinet and door; Cabinet and door form an airtight electric elements installing space, and the sheet material of side cabinet, base plate, top board and door all is to adopt the two-layered steel plates assembly welding to form, and wherein, is filled with the insulation insulating layer of asbestos between sheet metal layer, and the specular aluminium rete is posted on the inner layer steel plate surface; In above-mentioned airtight electric elements installing space, indoor apparatus of air conditioner is installed; Above-mentioned cabinet side appearance or door are fixed with air conditioning chamber's outdoor main unit in appearance; There is refrigerant pipe to be connected with electric control circuit between indoor apparatus of air conditioner and the air conditioning chamber's outdoor main unit.
Compared with the prior art, the utility model adopts the split-type air conditioner unit of technology maturation to be combined with cabinet, has overcome the low defective of semiconductor refrigerating module Energy Efficiency Ratio.In the time of can guaranteeing to install on the spot, temperature humidity satisfies the requirement of electronic devices and components humiture, and the damage of avoiding electronic devices and components to cause because of the humiture environment guarantees that protection and automatic safety device normally move.
The key technical indexes that the utility model can reach is as follows:
Temperature range: be lower than 35 ℃;
Humidity range: be lower than 70%;
Energy Efficiency Ratio: 〉=3.
