Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Embodiment 1:
As shown in Figure 1; The humidity detection protective device of switched reluctance motor controller comprises humidity sensor, signal processing unit, control unit, wherein; Humidity sensor is connected with signal processing unit; The output of signal processing unit is connected with control unit, and the output of control unit is connected with warning device, dehydrating unit and major loop locking device respectively, and power supply is connected with signal processing unit, control unit, dehydrating unit respectively.
Warning device can be audio alerting unit or light alarming device, and better, it can be sound equipment and light integral type warning device.
Described dehydrating unit is fan, air-conditioning or is heater.Better, dehydrating unit is the combination of heater and fan.For example can select the pectination aluminium alloy electric heater that aims at the moistureproof dehumidification design of power equipment for use, it is to be processed by resistive heater and pectination aluminium alloy heating panel.
Above-mentioned major loop is meant the major loop of switched reluctance motor controller; The humidity detection protective device of the switched reluctance motor controller of the utility model; Be independent of the major loop of switched reluctance motor controller, i.e. the humidity detection protective device of the major loop of switched reluctance motor controller and the switched reluctance motor controller operation that powers on separately.Therefore, the power supply in the humidity detection protective device of switched reluctance motor controller is an independently electric power loop, avoids clashing with the major loop of switched reluctance motor controller.
Above embodiment is this patent preferred embodiments, and other distortion execution modes that those skilled in the art associate under the thought of this patent is guided are also in this protection range.
Operation principle and use:
During real work, described major loop locking device is a relay, and a contact of relay is series at the start loop of switched reluctance motor controller.The humidity detection protective device of starting switch reluctance motor controller at first; The major loop of switched reluctance motor controller is in the monitoring wait state; If the humidity of humidity detection protective device monitoring is lower than set point; Described major loop locking device output closure signal can allow the major loop of switched reluctance motor controller to work on power.If the humidity of humidity detection protective device monitoring is higher than set point, described major loop locking device output cut-off signals does not allow the major loop of switched reluctance motor controller to work on power.So, just avoid the damage of the inner components and parts of switched reluctance motor controller, guaranteed the safe operation of electric equipment.
Humidity sensor is in order to the humidity in the sense switch reluctance motor controller; The signal of humidity sensor exports signal processing unit to, handles in order to the signal to humidity sensor, is transformed to the standard analog voltage signal.Humidity sensor is non-sealing, is accuracy and stability that protection is measured, should avoid in acid, alkalescence as far as possible and contain in the atmosphere of organic solvent using.Also avoid in the bigger environment of dust, using.Be the humidity in correct reflection desire survey space, also should avoid transducer is placed in from place, the too near or airless dead angle of wall.If tested room is too big, just should place a plurality of transducers.
Through the processing of signal processing unit, the signal of humidity sensor becomes can be by the voltage signal of back level processing, and it inputs to control unit, through the comparison of control unit setting numerical value and signal processing unit input signal, in order to external output switching manipulation.If humidity surpasses set point, control unit can drive warning device and report to the police, and can drive dehydrating unit and carry out dehumidifying work.
