Abstract
The utility model relates to a frequency converter with an electrolytic capacitor fixing seat. The frequency converter comprises a frequency converter body, wherein an IGBT (Insulated Gate Bipolar Translator) module, an electrolytic capacitor and a radiating device are arranged in the frequency converter body, a fixing seat is arranged in the frequency converter body, an electrolytic capacitor hole is formed in the fixing seat, and the electrolytic capacitor hole is matched with the electrolytic capacitor. The frequency converter has the beneficial effects that the electrolytic capacitor is stably arranged in the frequency converter by the adoption of the fixing seat, so that the service life of the frequency converter is prolonged.
Description
Technical field
The utility model relates to the converter technology field, especially relates to a kind of frequency converter with electrochemical capacitor holder.
Background technology
Frequency converter is to use converter technique and microelectric technique, controls the electric control appliance of alternating current motor by changing machine operation supply frequency mode.Frequency converter mainly is comprised of rectification (AC-DC), filtering, inversion (direct current becomes interchange), brake unit, driver element, detecting unit microprocessing unit etc.Reach the purpose that changes supply voltage by the frequency that changes power supply; provide its needed supply voltage according to the actual needs of motor, and then reach purpose energy-conservation, speed governing, in addition; frequency converter also has a lot of defencive functions, as overcurrent, overvoltage, overload protection etc.Along with improving constantly of industrial automatization, frequency converter has also obtained using very widely.Exist some problems in existing frequency converter, for example, the electrochemical capacitor group is not to adopt fixed installation, and the locational space of depositing electrochemical capacitor is larger, and electrochemical capacitor rocks, and the problems such as solder joint disengaging easily occur, and causes frequency converter to damage and can't work.
Therefore, a kind of appearance of the frequency converter with electrochemical capacitor holder is necessary.
