Air dehumidifier in above-mentioned two kinds of electrical equipment racks, the former is independently heater plate, although in actual use dehumidification rate and quality better, volume is too large, installs inconvenience, is unwell in electric substation's power switch cabinet and uses.Though the latter is semiconductor refrigeration chip heating; because inside does not arrange short circuit, overvoltage and overheated automatic protection; and manual gear operation self-resetting; can not be effectively protected in time when there is operation irregularity; especially can not effectively dispose when unattended, and contour structures does not meet electric substation's power switch cabinet installation requirement.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of power switch cabinet special-purpose air dehumidifier.Adopt the flame retardant plastics shell of excellent insulating property, compact, more meet installation requirement in power switch cabinet, outside casing, be provided with circulating ventilation window and condensate water discharging hole; Switching Power Supply has the self-protection function of overcurrent, short-circuit protection, control circuit and have manual gear to switch the automatic catch of unmanned state voluntarily, forgets the deficiency of switching when being specially adapted to unattended.
The technical scheme in the invention for solving the above technical problem is: a kind of power switch cabinet special-purpose air dehumidifier, comprise by casing, semiconductor chilling plate, temperature sensor, humidity sensor, fin, thermal insulation board, condensate film, small fan, exhaust outlet, air inlet, control circuit and Switching Power Supply, form the dehydrating unit that humiture regulates automatically, described semiconductor chilling plate is that a kind of front and back two potsherd can produce cold and hot element respectively when being energized, and be installed between fin and the interlayer of condensate film in embedded thermal insulation layer together with temperature sensor, form the cooling and warming assembly with Temperature Humidity Sensor, it is characterized in that the fin side correspondence of cooling and warming assembly is arranged on after the inner small fan of casing exhaust outlet, condensate film corresponds to the condensed water gathered trough of casing lower end band apopore.
Thermal insulation layer is had between described fin and condensate film, semiconductor chilling plate is together with temperature sensor in embedded thermal insulation layer, wherein, the hot junction of semiconductor chilling plate is pasted on fin plane, and the cold junction of semiconductor chilling plate and temperature sensor are pasted on condensate film plane.
Described condensed water gathered trough, position corresponds to below condensate film, is rectangle frame in casing lower end one, and has apopore to reach the outer bottom of casing.
Described humidity sensor is arranged in the upper left quarter through hole protective cover outside casing, forms site environment Humidity Detection.
Described air inlet is positioned at the outer lower left side of casing and lower right side, forms hot-air flow channel with cooling and warming assembly, small fan, exhaust outlet.
Described control circuit and Switching Power Supply respectively in casing cooling and warming assembly top install before and after, power supply terminal is installed on casing lower end.
Compared with prior art, the utility model has the advantage of:
(1), global design is the special characteristic according to power switch cabinet inner structure and meets actual operation requirements; (2), casing is also provided with ambient humidity sensor outward, provides the parameter of ambient humidity, can carry out automatic dehumidifying to the air in power switch cabinet; (3), be provided with short circuit, overvoltage, overheated automatic protection and manual gear operation time after wait some seconds just understand be transformed into automatic catch voluntarily by manual mode; (4), Switching Power Supply is adopted to power, energy-conservation safety again, the advantage that application cost performance is high.
