The invention provides a frequency converter control box
aging test device which comprises a
voltage and current aging module, an
optical fiber aging module, a temperature aging module and a
logic control aging module. The
voltage and current aging module is used for simulating
alternating current signal waveforms outputted by a
voltage sensor and a
current sensor and aging voltage and current acquisition ports, the
optical fiber aging module is used for simulating
optical fiber feedback signals and / or
motor speed signals outputted by an IGBT (
insulated gate bipolar transistor), acquiring signals for controlling the IGBT to actuate,
processing IGBT actuating signals and judging whether the waveforms are consistent with a standard waveform or not, the temperature aging module is used for simulating temperature rise acquired by a temperature acquisition port and accordingly completing an over-temperature alarm aging process, and the
logic control aging module is used for simulating receiving and transmitting of logic switch actuating signals and judging whether actuating is executed or not. The frequency converter control box
aging test device has the advantages that offline comprehensive
aging test for all portions and electronic components of a control box is performed by means of long-time high-temperature operation, the quality of the control box is ensured, the aged control box cannot be damaged and the like.
