In order to address this problem, the normal method adopting is, at switchgear house, the air exhausting device of controlling is manually installed at present, and by O&M personnel, the cycle is carried out manual operation in accordance with regulations.Bring thus 2 problems, the 1st, increase hand labor amount, improve operation cost; The 2nd, can make an inspection tour and proof cycle is long or it is half-hearted to work because of O&M personnel, and cause the humidity and temperature of switchgear house to exceed standard.
Utility model content
The utility model provides a kind of control system for switchgear house air exhausting device, it is characterized in that, comprise: thermometer, temperature switch device, humidometer, humidity switching device, thermal relay, A.C. contactor and air exhausting device, wherein thermometer and the series connection of temperature switch device, humidometer and humidity switching device series connection, thermometer and temperature relay are relations in parallel with humidometer and humidity switching device, temperature switch device and humidity switching device are connected to respectively one end of thermal relay, the other end of this thermal relay connects one end of A.C. contactor, the other end of this A.C. contactor connects air exhausting device.
Wherein said A.C. contactor is for being switched on or switched off the current supply circuit to air exhausting device.
Wherein said thermal relay plays the effect of short circuit and overload protection.
The conducting when equaling 40 DEG C of the temperature of wherein said temperature switch device in switchgear house, the temperature in switchgear house disconnects during lower than 30 DEG C.
The conducting when humidity of wherein said humidity switching device within humidometer shows switchgear house is more than or equal to 80%, disconnects when the humidity within humidometer shows switchgear house is less than 70%.

Brief description of the drawings
Fig. 1 is the structural representation of the control system for switchgear house air exhausting device of the present utility model.
Embodiment
Fig. 1 is the structural representation of the control system for switchgear house air exhausting device of the present utility model.As shown in the figure, this control system comprises:
Thermometer, temperature switch device, humidometer, humidity switching device, thermal relay, A.C. contactor and air exhausting device, wherein thermometer and the series connection of temperature switch device, humidometer and humidity switching device series connection, thermometer and temperature relay are relations in parallel with humidometer and humidity switching device, temperature switch device and humidity switching device are connected to respectively one end of thermal relay, the other end of this thermal relay connects one end of A.C. contactor, and the other end of this A.C. contactor connects air exhausting device.
This thermometer is for measuring the temperature in switchgear house.
This humidometer is for measuring the humidity in switchgear house.
Temperature switch device is connected circuit when equaling 40 DEG C for temperature in switchgear house, the open circuit during lower than 30 DEG C of the temperature in switchgear house, thus control energising or the power-off of A.C. contactor.Certainly, according to actual needs, any threshold temperature can also be set, to make this temperature switch device conducting or disconnection under this set temperature.
When being more than or equal to 80% for the humidity within humidometer shows switchgear house, connects humidity switching device circuit, the open circuit when humidity within humidometer shows switchgear house is less than 70%, thereby energising or the power-off of control A.C. contactor.Certainly, according to actual needs, any threshold value humidity can also be set, to make this humidity switching device, at this, conducting or disconnection under humidity are set.
This A.C. contactor is for being switched on or switched off the current supply circuit to air exhausting device.
This thermal relay plays the effect of short circuit and overload protection.When overload situations appears in the motor in short circuit or air exhausting device appear in current supply circuit, this thermal relay disconnects, thereby has disconnected the coil circuit of A.C. contactor, then cuts off the power supply to motor, motor is stopped and protected.
At work, thermometer is measured the temperature in switchgear house, thereby when starting action, the temperature switch device when equaling 40 DEG C of the temperature in switchgear house connects circuit, in the time that electric current flows through the coil circuit of A.C. contactor, the coil magnetization of this contactor starts, make the motor start-up in air exhausting device carry out air draft cooling, be equivalent to automatically start air exhausting device; Thereby when the temperature in switchgear house during lower than 30 DEG C temperature switch device start action open circuit, make no current flow through the coil circuit of A.C. contactor, thereby cut off the power supply to the motor in air exhausting device, be equivalent to automatically turn off air exhausting device.Humidometer is measured the humidity in switchgear house, when the humidity within humidometer shows switchgear house is more than or equal to 80%, thereby humidity switching device starts action connection circuit, in the time that electric current flows through the coil circuit of A.C. contactor, the coil magnetization of this contactor starts, make the motor start-up in air exhausting device carry out air draft dehumidifying, be equivalent to automatically start air exhausting device; When the humidity within humidometer shows switchgear house is less than 70%, thereby humidity switching device starts action open circuit, make no current flow through the coil circuit of A.C. contactor, thereby cut off the power supply to the motor in air exhausting device, be equivalent to automatically turn off air exhausting device.Thus, according to the control system for switchgear house air exhausting device of the present utility model, can realize the object of automatic dehumidifying and cooling.
Control system for switchgear house air exhausting device of the present utility model simple in structure, cheap, safe and reliable, automaticity is high, is applicable to the automation control of the air exhausting device of all kinds of switchgear houses.
