Sensor and blower fan connection；The temperature sensor is used for the temperature for monitoring box-type substation；Control chip is used for when temperature is higher than
During temperature threshold, start blower fan, when temperature is not higher than temperature threshold, close blower fan.When actually realizing, above-mentioned control chip
Can be single-chip microcomputer, Digital Signal Processing dsp chip.
By the above-mentioned means, the blower fan in cooling device can be made just to start when higher than temperature threshold, cooling has been saved
The power consumption of equipment, improves the intelligence degree of cooling device control.
In order to improve the mode grade of box-type substation, above-mentioned cooling device also includes humidity sensor and heating plate；Should
Humidity sensor and heating plate are connected with control chip respectively；Humidity sensor is used for the humidity for monitoring box-type substation；Control
Chip is used to, when humidity is higher than humidity threshold, start heating plate, when humidity is not higher than humidity threshold, close heating plate.It is logical
Often, above-mentioned heating plate is arranged at the bottom of box-type substation.
By the above-mentioned means, the change electrification that box-type substation can be avoided to cause in wet condition, keeps box and becomes
Power station inner air is dried.
A kind of cooling device for box-type substation provided in an embodiment of the present invention, is assemblied in the door body of box-type substation
On, heat exchange power is 7.5KW, mainly for 10 groups of 15KW DC chargings module efficiencies be 95% in the case of design.Cooling is set
Standby to be divided into two parts by boundary of door, cooling device is in door after the heat absorption of part, and vacuum is filled in refrigerant in radiator by liquid
State is converted into gaseous state, is shifted to part outdoors, and inside is back to after being cooled to liquid through air and is absorbed heat again, and so circulation is real
Now efficiently cooling.Centrifugal blower is equipped on cooling device simultaneously, noise is small, realizes inner ventilation, it is ensured that cold wind slave module inlet air
Mouth enters, from the back air-out of box-type substation, the air self-loopa in box-type substation.Simultaneously in the direct current of box-type substation
Charging module air intake vent reload temperature sensor carries out intelligent control, just starts interior circulation blower fan when the set temperature is reached, low
The conversion heat absorption of radiator gas-liquid is only needed in design temperature, any electric energy is not expended.
Because the door body because of cooling device and box-type substation can realize good assembling, blower fan can make box type transformation
The inner air stood realizes self-loopa, thus box-type substation can ensure higher degree of protection, condensation, dirt problems
It can well be suppressed, can increase humidity sensor and heating plate to control in moister severe area, case change
Humidity.
