Operation principle of the present utility model is as follows:
By control centre 14 to carrying out radiating control in cabinet 1, control process is as shown in figure 4, comprise the following steps:
Step 110:Control centre 14 reads the temperature value of each temperature sensor 15;
Step 120:Control centre 14 contrasts the temperature value of each temperature sensor 15 and corresponding preset value;
Step 130:Control centre 14 judges whether the temperature value of each temperature sensor 15 is more than corresponding preset value;
In this step, if the temperature value of each temperature sensor 15 is not above corresponding preset value, return is held Row step 110, if the temperature value of some temperature sensor 15 is more than corresponding preset value, perform step 140;
Step 140:Control centre 14 judges whether the rotating speed of radiator fan 31 is more than preset rotation speed;
In this step, if the rotating speed of radiator fan 31 is less than preset rotation speed, step 150 is performed, if radiation air The rotating speed of fan 31 is more than or equal to preset rotation speed, then performs step 160;
Step 150:Control centre 14 adjusts the rotating speed of radiator fan 31 to preset value;
Step 160:Control centre 14 adjusts the refrigerating capacity of refrigerator, strengthens the refrigeration in cabinet 1.
Under the control of control centre 14, intelligent heat dissipation can be achieved, keep the temperature in cabinet 1 to be in safe range, Hot-air is sucked in cool air reflux cabin 5 after the cooling of refrigerating layer 4 by drawing fan in cabinet 1, in the process, cold air Respectively by drawing fan rear end except the dedusting of knoisphere 6 and except wet layer 7 dehumidifies, thus the air in cool air reflux cabin 5 is temperature Relatively low clean dry air is spent, in the presence of suction fan 13, is come back to by cool air reflux pipe 8 in cabinet 1, So as to realize, air exchanges in cabinet 1, improves radiating efficiency.
Control centre 14 is simultaneously also to carrying out pressure control in cabinet 1, control process is as shown in figure 5, comprise the following steps:
Step 210:Control centre 14 reads the atmospheric pressure intensity values of each barometer 16 under inlet close state;
Step 220:Control centre 14 contrasts the atmospheric pressure intensity values of each barometer 16 and corresponding preset value;
Step 230:Whether control centre 14 judges the atmospheric pressure intensity values of each barometer 16 beyond corresponding values;
In this step, if the atmospheric pressure intensity values of the measurement of each barometer 16 are without departing from corresponding values, explanation Air pressure in cabinet 1 is suitable, returns and performs step 210;If the atmospheric pressure intensity values of some barometer 16 measurement are beyond corresponding pre- If being worth scope, illustrate the atmospheric pressure value in cabinet 1 not in safe range, when atmospheric pressure value is too high, in fact it could happen that power distribution cabinet explodes Danger, now perform step 240;
Step 240:Control centre 14 sends to cylinder 10 and instructed, and makes cylinder 10 control retractable door 9 to open air inlet.
In this step, air inlet open, makes in cabinet 1 and the outer air flow of cabinet 1 leads to, and the atmospheric pressure value in cabinet 1 can be by Gradually return in default safe range, now control centre 14 sends to cylinder 10 and instructed, and makes cylinder 10 control retractable door 9 to close Close air inlet.
Damp-proof pedestal 2 is used to prevent the moisture of the bottom of cabinet 1 from penetrating into cabinet 1, and the equipment in power distribution cabinet is impacted, So as to trigger potential safety hazard.In use, first setting the pit of suitable size in earth's surface 251, the side wall of cavity is arranged on pit Interior, the upper end level of side wall is higher than earth's surface 251, forms new pit, the filling infiltration sand into new pit, forms infiltration area 24, interlayer 22 is installed in the top of infiltration sand, then water-absorption material is filled in the new pit that interlayer 22 and cavity wall are formed Material, form moisture absorption area 23;By the mounting of roof plate of cavity above side wall, that is, complete the installation of damp-proof pedestal 2.Finally by power distribution cabinet It is placed on base, and is stuck between fixed lobe 21.
Damp-proof pedestal 2 is in the moisture absorption area 23 formed below of power distribution cabinet and infiltration area 24, the infiltration sand energy to seep water in area 24 Effectively prevent underground moisture from evaporating to flow up, the interlayer 22 in base can effectively obstruct groundwater evaporation and be upwardly into distribution Cabinet, even if moisture is penetrated on interlayer 22, it can also be absorbed by the absorbent material in moisture absorption area 23, and due to the resistance of cavity top plate Every, it is further to prevent to alter into power distribution cabinet on moisture, so as to ensure the safe operation of equipment in power distribution cabinet, extend distribution The service life of cabinet.The humidity value in moisture absorption area 23 is detected by the humidity sensor 17 in moisture absorption area 23 and fed back in control Humidity value compared with default humidity range, is judged whether to need to change the water suction in moisture absorption area 23 by the heart, control centre Material, improve moisture effect.
Therefore, power distribution cabinet provided by the utility model, there is excellent ventilation and heat, protection against the tide, the dust-proof and function such as explosion-proof, Use securely and reliably, be worthy of popularization.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, although ginseng The utility model is described in detail according to previous embodiment, for those skilled in the art, it still can be with Technical scheme described in foregoing embodiments is modified, or equivalent substitution is carried out to which part technical characteristic.It is all Within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., this practicality should be included in Within new protection domain.
