Compensation phase advancer for high-low-voltage winding electric motor

Abstract

The invention provides a compensation phase advancer for a high-low-voltage winding electric motor. The phase advancer for compensation of the electric motor adopts a single chip microcomputer as a control circuit, wherein a wire coupling stator current detection circuit, a silicon controlled trigger circuit, 12 groups of silicon controlled circuits, a Chinese character display circuit, a rotor current detection circuit and a stator voltage detector are arranged on pins on the periphery of the single chip microcomputer respectively. The single chip microcomputer is taken as a core processing element, a silicon controlled mode is adopted, during use, change of the operation state of the motor can be tracked automatically, and relevant parameters can be adjusted atomically, so that the optimal compensation effect can be realized, meanwhile, Chinese character display is configured, the operation change condition can be mastered intuitively, the whole device does not have a rotating component, the reliability is high, and the maintenance is convenient.

Description

technical field [0001] The invention relates to a device for compensating the operation of a motor, in particular to a compensation phase advancer for high and low voltage winding motors. Background technique [0002] The currently known rotor current phase of high and low voltage wound motors is a compensation method of alternating and variable frequency. When in use, the stator current and power factor of the motor are measured by pointer ammeter and power factor meter, and the power factor is fine-tuned by " Change the tap of the voltage transformer after phase dephasing, and at the same time it is difficult to find out and deal with it in time after the equipment fails. Contents of the invention [0003] The purpose of the present invention is to provide a high and low voltage winding motor compensation phase advancer, which can automatically track and detect the motor and automatically adjust relevant parameters to make it in the best operating state. [0004] The in...
