Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is that the condensation of the utility model wind-powered electricity generation unit detects, the circuit theory diagrams of cancellation element.As shown in Figure 1, the condensation of a kind of wind-powered electricity generation unit of the utility model electric-control system detects, cancellation element, comprises condensation sensor 10, condensation sensor detection circuit 20, CPU processor unit 30, auxiliary reclay driving circuit 40 and electric heater and blower fan 50; Described condensation sensor 10 is electrically connected to by wire with condensation sensor detection circuit 20, the output circuit of condensation sensor detection circuit 20 is electrically connected to the input circuit of CPU processor unit 30, and the output circuit of CPU processor unit 30 is electrically connected to electric heater and fan unit 50 by auxiliary reclay driving circuit 40.Condensation sensor 10 is arranged on the position that condensation detection need to be carried out in electrical cabinet of wind turbine generator unit inside; Condensation sensor detection circuit 20 by measure change in voltage on condensation sensor and with setting voltage comparison, thereby judge, whether there is condensation to exist, and send this signal to CPU processor unit 30, CPU processor unit 30 is by controlling auxiliary reclay driving circuit 40, auxiliary reclay is carried out to switching control, and then electric heater and fan unit 50 are opened, stop to control, thereby realize the object of eliminating condensation.The inside of described electric heater and fan unit 50 is provided with thermel protection device.
The course of work of the present utility model, first, condensation sensor 10 feeds back the condensation situation in electrical cabinet of wind turbine generator unit by the variation of resistance, condensation sensor detection circuit 20, by operational amplifier, gather the change in voltage of condensation sensor, this magnitude of voltage and default magnitude of voltage are compared, and send CPU processor unit 30 to; CPU processor unit 30 obtains after the interior condensation situation of cabinet, and output voltage signal, controls auxiliary reclay driving circuit 40 and remove to control auxiliary reclay; After isolation by auxiliary reclay, output, the power supply of electric heater and fan unit 50 is carried out to switching control, realizes the on off control of electric heater and blower fan, so realize the dehumidifying of wind-powered electricity generation unit, except the object of condensation.Meanwhile, electric heater and blower fan have thermel protection device, can effectively protect the overheating fault of electric heater and blower fan, realize the reliability service except condensation.
It is specifically divided into two kinds of duties:
1, the starting state of condensation elimination work:
When electrical cabinet of wind turbine generator unit inside has condensation to produce, condensation sensor has detected condensation, and its resistance declines, and feedback voltage promotes, the comparer by condensation sensor detection circuit 20 and setting voltage relatively after, output low level is to CPU processor unit 30; CPU processor unit 30 receives after this signal, goes to control the switching of auxiliary reclay by controlling auxiliary reclay driving circuit 40; After isolating, export by auxiliary reclay again, connect the power supply of electric heater and fan unit 50, realize the startup running of electric heater and blower fan, realize the object that dehumidifies, removes condensation.In eliminating the process of condensation, if overheating fault appears in electric heater, by the thermel protection device of electric heater inside, disconnect the power path of well heater, until its temperature, return to heat protection limit value when following, then restart well heater.
2, the halted state of condensation elimination work:
After electrical cabinet of wind turbine generator unit internal condensation is eliminated, condensation sensor 10 detects without condensation, and its resistance rises, and feedback voltage declines, the comparer by condensation sensor detection circuit 20 and setting voltage relatively after, export high level to CPU processor unit 30; CPU processor unit 30 receives after this signal, goes to control the switching of auxiliary reclay by controlling auxiliary reclay driving circuit 40; After isolating, export by auxiliary reclay again, disconnect the power supply of electric heater and fan unit 50, realize shutting down of electric heater and blower fan, finish dehumidifying, remove condensation.
Of the present utility model owing to adopting the inside that condensation detects, cancellation element is arranged on electrical cabinet of wind turbine generator unit, the mode of direct-detection condensation, avoided cannot reflecting by traditional detection ambient humidity the shortcoming of condensation state, can reliably realize detection and the elimination of condensation, make the electric-control system of wind-powered electricity generation unit adapt to high humility, have the climatic environment of condensation; Have simple in structurely, be easy to install, eliminate in real time condensation, effectively protect the advantages such as unit safety operation.
