Description
Technical field
The present invention relates to inverter, specifically is a kind of ultra-low temperature application traction inverter.
Background technology
In mining operation, engineering tunnel operation, the electric locomotive that adopts the track traffic traction in a large number is as auxiliary running tool.In long-term application process, especially domestic, what adopt in a large number is the drive pattern of DC drive mode, because its intrinsic shortcoming of direct current, thereby bring fault rate height, maintenance workload big, and follow the development of power electronic devices technology, the at high speed binistor grows up gradually for the AC driving on basis, AC driving promptly refers to adopt the AC traction electric motor operation in the inverter control electric locomotive, thereby realizes the tractive characteristic of electric locomotive.But owing to mining operation, engineering tunnel operation are distributed in extremely frigid zones in a large number, often cause the inverter can't normal operation under ultralow temperature (generally below-25 ℃) condition, thereby make AC driving often can't carry out, brought negative effect to production.Be necessary to invent a kind of novel inverter that also can normal operation under condition of ultralow temperature for this reason.
Summary of the invention
The present invention provides a kind of ultra-low temperature application traction inverter in order to solve the problem that existing inverter can't normal operation under condition of ultralow temperature.
The present invention adopts following technical scheme to realize: ultra-low temperature application traction inverter, comprise inverter circuit and control circuit, and control circuit comprises DSP control module, logic processing module, signal processing module and communication module; The input end of DSP control module links to each other with the mouth of logic processing module, the mouth of signal processing module, the signal transmission ends of communication module respectively; The input end of logic processing module is connected with input/output module; The mouth of DSP control module is connected with driver module and heating control module respectively, and the mouth of heating control module is connected with heater circuit; The input end of signal processing module links to each other with the acquisition of signal end of inverter circuit; The mouth of driver module links to each other with the control end of inverter circuit.Described inverter circuit, DSP control module, logic processing module, signal processing module, communication module, input/output module, driver module, heating control module, heater circuit are existing known configurations.
During work, driver's control signal of electric locomotive inputs to the DSP control module through input/output module, logic processing module successively, the DSP control module is controlled inverter circuit by driver module under the support of corresponding software immediately, finally controls the operation of AC traction electric motor; Meanwhile, the voltage and the current signal of the speed signal of AC traction electric motor, the temperature signal of surrounding environment, inverter circuit all are input to the DSP control module through signal processing module, the DSP control module is controlled inverter circuit by driver module under the support of corresponding software; Input end at signal processing module connects temperature sensor, when ambient temperature is in ultralow temperature, temperature sensor transfers to the DSP control module with the temperature signal of being gathered by signal processing module, the DSP control module starts heater circuit by heating control module thus, make ambient temperature raise, guarantee the normal operation of ultra-low temperature application traction inverter; Signal transmission ends at communication module connects external debugger, and under the support of corresponding communications protocol, external debugger can be carried out on-line debugging and detection to the DSP control module by communication module.
The present invention is reasonable in design, easy to use, efficiently solves the problem that existing inverter can't normal operation under condition of ultralow temperature, is applicable to mining operation, the engineering tunnel operation of extremely frigid zones.
