Description

A kind of environmental control system of wind-powered electricity generation electrical control cabinet
Technical field
The utility model relates to electrical control equipment field, particularly relates to a kind of environmental control system of wind-powered electricity generation electrical control cabinet.
Background technology
In recent years, energy problem is day by day serious, and particularly outstanding in China, the fast development of wind-powered electricity generation can slow down China's energy crisis.Wind turbines needs the large-scale maintenance of at least twice every year, but blower fan is generally arranged on open, meagrely-populated place, the regions such as great Northwest, and operational environment is extremely severe, and this brings great difficulty to wind-powered electricity generation service work.
Annual maintenance is generally in summer and winter, and staff will to experience in cabin in freezing winter and in sultry summer, and operational environment severe is like this unfavorable for increasing work efficiency, and also has threat to staff's personal safety.
Meanwhile, rugged environment also can cause damage to wind power equipment, as can not abnormal environment situation in Timeliness coverage cabin, likely causes wind power equipment premature aging, loss, brings huge property loss.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of structure simple, can monitor and regulate the environmental control system of the wind-powered electricity generation electrical control cabinet of blower fan environment.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of environmental control system of wind-powered electricity generation electrical control cabinet, it is characterized in that, comprise PLC, described PLC connects thermostat, described thermostat connects multiple temperature sensor, and described temperature sensor comprises electromechanical transducer, frequency converter transducer and tank sensor device;
Described PLC connects the hygrometer being used for detecting box humidity;
Described PLC connects lighting device, and described lighting device comprises LED and the limit switch for controlling the opening and closing of described LED.
Described PLC is also connected with warning device.
Described warning device comprises warning lamp and buzzer.
Described thermostat is also connected to heater and fan respectively.
Described heater is provided with the fin that size matches.
Described heater is resistance heater.
Described limit switch is installed on the hinge of control cubicle cabinet door.
The beneficial effects of the utility model are: wind-powered electricity generation control cubicle major part is in fan engine room, and some rotates along with wheel hub, often early than high temperature, severe cold environment, also can run into humid air and cause equipment to be oxidized.
The utility model thermostat connects multiple temperature sensor, because the temperature in motor, frequency converter and control cubicle casing is inconsistent, this setup can the real time temperature of the above-mentioned several main heating part of comprehensive monitoring, and feed back to PLC in time, be convenient to controllers and make suitable adjustment, also can prevent the harm caused because temperature is too high.Meanwhile, PLC connection hygrometer by control cubicle humidity information Real-time Feedback to the staff of remote control, can avoid problems such as causing that equipment is corroded because humidity is too high.
Secondly, because control cubicle all can have regular maintenance (mainly in the 5-6 month and the 11-12 month) every year, when the operational environment of staff in cabin is extremely severe, the phenomenon such as occur heatstroke at work for preventing staff or catch cold, the utility model PLC is connected with warning device, described warning device is when PLC detects that spin manifold temperature is too high or too low, meeting be glimmered by warning lamp and buzzer warning points out staff to note reducing temperature of heatstroke prevention, also can staff be pointed out to carry out service work when other faults appear in this control system simultaneously.
In addition, in the utility model, thermostat is also connected with heater and fan, can spin manifold temperature in regulable control cabinet by the combination of both, and aids in and regulate motor and frequency converter temperature.When thermostat detects that spin manifold temperature is too low, control heater and fan start simultaneously, and described heater passes through the effect of fin and fan, strengthen cross-ventilation, make the temperature in control cubicle increase sooner.And when thermostat will measure spin manifold temperature too high time, then separately start fan control cubicle is lowered the temperature.
Finally, be throughout the year dark in wheel hub, overhaul the difficult problem of debugging for solving staff, the utility model is provided with lighting device, limit switch is arranged on the hinge of cabinet door, when closing cabinet door, limit switch is touched, and LED is extinguished, when opening cabinet door, limit switch is released, and LED lights, so not only convenient but also energy-conservation.
Accompanying drawing explanation
