A low-voltage energy-saving variable-frequency speed regulator

Abstract

The invention discloses a low-voltage energy-saving frequency conversion speed regulator, include mounting plate, three equidistant mounting holes are arranged at both ends of the upper surface of themounting plate, and the upper surface of the mounting plate is provided with a guide device, the screw side of the guide device is provided with a shock absorbing seat, the bottom plate of the shockabsorbing seat is movably sleeved on the side of the screw, a handle is arranged at the end of the right side of the bottom plate, a cover plate is arranged on the right side of the bottom plate, a side corresponding to the handle is provided with a strip-shaped hole, and the side corresponding to the screw is provided with a circular hole. A low-voltage energy-saving variable-frequency speed regulator Easy to fix, the position of the variable frequency speed regulator can be adjusted, Easy to maintain, it can protect the variable frequency speed governor from shock, improve the anti-collisionperformance of the variable frequency speed governor through the outer shell, and improve the heat dissipation effect of the variable frequency speed governor through the fan and the radiating fin, so as to prolong the service life of the variable frequency speed governor, reduce the waste of resources, and save energy and environment.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a low-voltage energy-saving frequency converter. Background technique [0002] The frequency conversion speed controller is a device that converts the power frequency power supply into various frequency AC power sources to realize the variable speed operation of the motor. The control circuit completes the control of the main circuit, the rectifier circuit converts the AC power into DC power, and the DC intermediate circuit controls the rectification. The output of the circuit is smoothed and filtered, and the inverter circuit reverses the direct current into alternating current. The existing frequency converter has poor heat dissipation effect and anti-collision performance, and it is easy to shorten the service life of the frequency converter, which is not energy-saving and environmentally friendly. After the governor is fixed, it cannot be adjusted, and maintenanc...
