The invention discloses a convenient-to-maintain frequency changer which comprises an upper cover, a bottom shell, a radiator, an electronic device, a power board and a control board. The radiator is fixedly mounted on the bottom shell through a fastening member, a fixing member and a radiator fixing member, a clamping groove is arranged on the fixing member, the radiator is inserted into the clamping groove through an insertion-type connecting member which is fixedly arranged on the radiator through the fastening member, the upper end of the power board is fixedly arranged on the insertion-type connecting member through a fastening member after being matched and positioned with a positioning column arranged on the bottom shell through a U-shaped groove, the upper end of a first protecting cover is fixedly arranged on the insertion-type connecting member through a fastening member after being matched and positioned with the positioning column arranged on the bottom shell through the U-shaped groove, and two sides of a second protecting cover are arranged on the radiator fixing member through the first protecting cover and a supporting frame. The convenient-to-maintain frequency changer is convenient to demount and maintain and flexible in wire incoming and outgoing, and loss caused when the frequency changer stops is reduced furthest.
Description
technical field [0001] The invention relates to a frequency converter which is easy to maintain. Background technique [0002] With the economic take-off of reform and opening up, in response to the call for energy saving and emission reduction, frequency converters are more and more widely used in industrial automation. Due to the influence of various factors, frequency converters often have some failures during use. The stay of these failures will bring inconvenience to production or life, resulting in waste of time and money. In order to make the inverter run safely and reliably, corresponding protective measures must be taken. [0003] Traditional inverters have a single way of entering and exiting wires, and the screws that lock each part need to be removed during wiring and maintenance, which makes it inconvenient to maintain independent components. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an easy-...
