Description

High-practicability frequency converter installation air duct Technical Field The utility model relates to the technical field of frequency converters, in particular to a frequency converter installation air duct with high practicability. Background The frequency converter is the power control equipment for controlling the alternating current motor by changing the working power supply frequency of the motor, the frequency converter air duct is used for radiating the power devices in the frequency converter, and the temperature rise is reduced by forced air cooling, so that the equipment can stably operate. The conventional frequency converter air duct pipe orifice position adopts the air inlet and outlet baffle to use as the dust screen, but the air inlet and outlet baffle interval is too big, and impurity easily gets into inside the casing through the wind channel, and part, frequency converter air duct pipe orifice position adopts the method of undetachable or bolt-up to install the filter, and impurity is accumulated easily on the filter, leads to the wind channel to be unable to ventilate the heat dissipation easily, but undetachable or bolt-up's method leads to the filter to install and remove comparatively loaded down with trivial details, inconvenient later stage inspection change.
