Abstract
The utility model relates to a converter field, concretely relates to converter suitable for severe cold district, including converter body, temperature sensor, controller, fan, heating device, its characterized in that: the fan, heating device have with the wind channel of converter body intercommunication is gone into the wind gap and is linked to each other with outside, and air outlet and converter body are inside to communicate with each other, the wind channel set up in the below of converter body, the wind channel sets up the fan with the inside communicating air outlet of converter body, the air outlet of fan inside the converter body. The utility model provides a pair of converter suitable for severe cold district is that the heater starts at temperature subnormality operating temperature, stops the heating when reacing normal operating temperature, has improved the application range of converter, has reduced the fault rate of converter, improve equipment's production efficiency.
Description
Technical field
The utility model relates to frequency converter field, is specifically related to a kind of frequency converter being applicable to extremely frigid zones.
Background technology
Inversion, the Important Components such as rectification module and reactor of frequency converter need normal operating ambient temperature, usually water-cooled or air-cooled is adopted time temperature is high, but frequency converter can not work equally normally in low temperature environment, so need when low temperature to increase ambient temperature, the reliability of laying dust problem to appliance component has an impact, frequency converter on the market generally only have heat radiation and dust-proof, seldom for extremely frigid zones use frequency converter.
Utility model content
For overcoming deficiency of the prior art, the utility model provides one can use in low temperature environment, improves the frequency converter scope of application, increases a kind of frequency converter being applicable to extremely frigid zones of the service efficiency of equipment.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of frequency converter being applicable to extremely frigid zones, comprise transducer body, temperature sensor, controller, fan, heater, it is characterized in that: described fan, heater has the air channel be communicated with described transducer body, air intake vent is connected with outside, air outlet and transducer body inside communicate, described air channel is arranged on the below of transducer body, the air outlet that air channel communicates with transducer body inside arranges fan, the air outlet of described fan is inner towards transducer body.
Further, described air intake vent place is provided with heater.
Further, described controller, when transducer body operating ambient temperature is lower than-10 DEG C, controls heater and starts, and when transducer body operating ambient temperature is higher than 5-10 DEG C, closes heater.
Further, described air intake vent place is provided with simple filter apparatus.
Further, be provided with filtering material in described simple filter apparatus, described filtering material at least comprises active carbon, filter cloth, thick cotton, the biochemical cotton of filtration.
Seen from the above description, a kind of frequency converter being applicable to extremely frigid zones that the utility model provides, a clean operational environment can be provided to frequency converter, simultaneously heater starting in temperature lower than normal working temperature, heating is stopped when arriving normal working temperature, improve the scope of application of frequency converter, reduce the failure rate of frequency converter, improve the production efficiency of equipment.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation being applicable to the frequency converter of extremely frigid zones of the utility model.
Embodiment
Below by way of embodiment, the utility model will be further described.
As shown in Figure 1, a kind of frequency converter being applicable to extremely frigid zones, comprise transducer body 1, temperature sensor 2, controller 3, fan 4, heater 5, it is characterized in that: described fan 4, heater 5 has the air channel 6 be communicated with described transducer body 1, air intake vent 61 is connected with outside, air outlet 62 and transducer body 1 inside communicate, described air channel 6 is arranged on the below of transducer body 1, the air outlet that air channel 6 communicates with transducer body 1 inside arranges fan 4, the air outlet of described fan 4 is inner towards transducer body 1, air intake vent 61 place is provided with heater 5, controller 3 is when transducer body 1 operating ambient temperature is lower than-10 DEG C, control heater 5 to start, when transducer body 1 operating ambient temperature is higher than 5-10 DEG C, close heater 5, air intake vent 61 place is provided with simple filter apparatus 611, filtering material is provided with in simple filter apparatus 611, described filtering material at least comprises active carbon, filter cloth, filter thick cotton, biochemical cotton.
As shown in the figure, the utility model in use, when ambient temperature is lower than-10 DEG C, temperature sensor 2 temperature sensor, by signal transmission to controller 3, controller 3 controls heater 5 and starts heating, when temperature is higher than 5-10 DEG C, temperature sensor 2 by signal transmission to controller 3, controller 3 cuts out heater 5, 4, fan is in opening always, when temperature is low, hot blast is sent to transducer body 1, improve operating ambient temperature, when heater 5 cuts out, wind is delivered to transducer body 1 and cool transducer body 1, easy filter 611 can ensure the air cleaning flowing into transducer body 1.
Above are only some embodiments of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection range.
