Description
Technical field
The utility model relates to a kind of electric equipment, and in particular, it relates to a kind of except switch cubicle.
Background technology
Switch cubicle is a kind of electric equipment, installs and fixes for various electric components, can maintain easily like this management, and facilitates wiring to install; Switch cubicle is owing to being connected with a large amount of circuit, and relative humidity in switch cubicle and the insulating properties of switch cubicle have very large relation, once the relative humidity in switch cubicle is excessive, can reduce the insulating properties in switch cubicle; And the connection place of part electric component is exposed, once the relative humidity in switch cubicle is excessive, also can make the current-carrying part of the electronic component in switch cubicle get rusty, and the resistance that can cause current-carrying part after getting rusty is excessive and generate heat, and then make the aging breakage of insulating barrier on electronic component, meeting initiation fire when serious; And switch cubicle is provided with cabinet door, in the time of Inspection and maintenance, need to often open cabinet door, and switch cubicle be generally also provided with louvre, so extraneous humid air can enter in switch cubicle, make the relative humidity of inside switch cabinet increase; At present traditional switch cubicle, for protection against the tide, is all the place that is placed on relatively dry, but the ground weather such as coastal is relatively moistening, so this dampproof method effect is poor; Current switch cubicle does not have special dehumidification function in a word, causes the relative humidity in switch cubicle higher, affects the fail safe of switch cubicle, so have certain room for improvement.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of special dehumidification function that has, thereby reduces relative humidity, improves the dehumidifying switch cubicle of fail safe.
For achieving the above object, the utility model provides following technical scheme: a kind of dehumidifying switch cubicle, comprise cabinet and cabinet door, in described cabinet, be provided with interstar connection room, described interstar connection room and cabinet internal communication, on described cabinet, be provided with circulation air pump, in described cabinet, be provided with drying chamber, in described drying chamber, be provided with drier, on described circulation air pump, be provided with air inlet and gas outlet, on described air inlet and gas outlet, be all connected with tracheae, described two tracheaes are all located in cabinet, and described drying chamber is arranged on tracheae.
By adopting technique scheme, in the time that in cabinet, relative humidity is excessive, operating personnel open circulation air pump, circulating air pump work, humid air in cabinet is drawn into circulation air pump from air inlet by tracheae, discharge from gas outlet again, enter in cabinet by tracheae, in drying chamber, be provided with drier, drier generally comprises silica gel, active carbon, calcium chloride and quick lime, there is extremely strong water absorption, water vapor adsorption in humid air can be fallen, thereby humid air is become to dry air, because drying chamber is arranged on tracheae, so circulation air pump in the course of the work, humid air can pass through drying chamber, steam is wherein after the absorption of drier, become dry air, and enter in cabinet, this design has special dehumidification function, thereby reduces relative humidity, improves fail safe.
The utility model is further set to: on described cabinet, be also provided with breather tank, described breather tank one end is provided with on screwed pipe and the other end and offers spiracle, described screwed pipe is communicated with breather tank, in described breather tank, be provided with discolour silica gel, on described cabinet, offer screwed hole, described screwed pipe is threaded with screwed hole.
By adopting technique scheme, discolour silica gel is also a kind of drier, the moisture in can absorbed air, thus reduce the relative humidity through the air of breather tank; In the time of circulating air pump work, drier falls the water vapor adsorption of air in cabinet, thereby make the pressure step-down in cabinet, can make so extraneous air pressure extruding cabinet, if cabinet good airproof performance, causes cabinet door to be not easy to open, if cabinet sealing is poor, extraneous humid air can constantly pour in cabinet, causes the relative humidity in cabinet again to improve; And the effect of breather tank is exactly when in cabinet when pressure step-down, extraneous humid air enters in breather tank from spiracle, and by after discolour silica gel, becomes dry air, and enter cabinet inside in screwed pipe; This design can balancing tank inside and outside pressure, and in the time that extraneous humid air enters cabinet, can adsorb the moisture in humid air, thereby ensure the relative humidity in cabinet.
The utility model is further set to: on described cabinet, be also provided with lithium chloride hygrometer, described lithium chloride hygrometer comprises probe and display screen, and described probe is located in cabinet, and described display screen is fixed on cabinet.
By adopting technique scheme, lithium chloride hygrometer is prior art, in probe, be provided with lithium chloride electrode, lithium chloride electrode can be from ambient gas adsorbed water steam and conducting electricity, thereby react relative humidity around by the size of current on lithium chloride electrode, display screen can convert the size of current on lithium chloride electrode to digital signal and feed back to user, so user is by watching display screen just can recognize the relative humidity in cabinet, thereby manually controlled circulation air pump, in the time that the relative humidity in cabinet is high, opening circulation air pump dehumidifies, in the time of relative humidity step-down in cabinet, close circulation air pump, this design can allow user recognize the relative humidity of cabinet, thus manual controlled circulation air pump.
The utility model is further set to: on described cabinet, offer ventilation mouth and installing port, described ventilation mouth is communicated with installing port, on described installing port, is provided with water swelling rubber.
By adopting technique scheme, water swelling rubber is a kind of existing watertight rubber material, when after water swelling rubber adsorption moisture, and meeting dilatancy; In the time that the relative humidity in cabinet is lower, water swelling rubber water suction is less, so only produce less dilatancy, cabinet can be breathed freely by ventilation mouth, thereby reduces the temperature in cabinet; In the time that the relative humidity in cabinet uprises, water swelling rubber absorbs more steam, thus produce larger dilatancy, thus block ventilation mouth, make cabinet sealing, prevent that extraneous humid air hole ventilation mouth from entering in cabinet; This design can make water swelling rubber in the time that relative humidity is higher, blocks ventilation mouth.
The utility model is further set to: described circulation air pump is fixed on cabinet outer wall, is provided with the through hole that air supply pipe wears on described cabinet, between described tracheae and through hole, is provided with seal.
By adopting technique scheme, it is tightr that seal can make that tracheae coordinates with through hole, thus the air-tightness of junction between guarantee tracheae and through hole; This design can prevent that airborne humid air from penetrating in cabinet.
