Abstract

A voltage-lowering liquid resistance of high-voltage AC electromotor with circular cooling system. The characteristic is: it includes the shell, at least three separated electric liquid boxes in the shell, the conductive liquid in the boxes, the electrode pair in the conductive liquid, and the reinforcing cooling system composed of the circular pump, the tube channel, the heat exchanger and the cooling medium, the input and output of the tube channel connect the electric liquid box; one pole of the electrode pair links to the high-voltage power end of the controlled device through the electrode arm, set insulation layer between the circular cooling system and the shell. This invention is applied to the startup or voltage adjustment of mouse cage and high-voltage AC generator.

Description

technical field [0001] The invention relates to a high-voltage AC motor voltage-reducing liquid resistance device, in particular to a high-voltage AC motor voltage-reducing resistance device capable of continuous and stable operation for a long period of time, which is used for starting or voltage-regulating and speed-regulating operation of the high-voltage AC motor. The invention belongs to the technical field of step-down operation control of a squirrel cage or a synchronous high-voltage high-power motor. Background technique [0002] Most of the known liquid-state soft starters for high-voltage AC motors are composed of electro-hydraulic tanks, conductive liquid in the electro-hydraulic tank, and electrode pairs in the conductive liquid. Wherein, the electrode pair can be two fixed electrodes, or a moving electrode and a fixed electrode, and the moving electrode is connected with the set transmission mechanism. When the liquid soft starter is used in conjunction with a ...
