Fluidic resistor device used for high-voltage fluidic resistor soft start cabinet

Abstract

The invention discloses a fluidic resistor device used for a high-voltage fluidic resistor soft start cabinet. The fluidic resistor device used for the high-voltage fluidic resistor soft start cabinet comprises a cabinet body, wherein the cabinet body is divided into an upper layer and a lower layer by a partition plate; the lower layer of the cabinet body is provided with one or a plurality of fluidic resistor boxes; the upper layer of the cabinet body is provided with a vacuum contactor positioned on the partition plate; a left side and a right side in each fluidic resistor box are each provided with a polar plate; the vacuum contactor is connected with the polar plates in the fluidic resistor box by copper bars; each fluidic resistor box is of a double-layer structure and consists of an inner box body and an outer box body; back-up blocks are arranged between the inner box body and the outer box body; the inner wall of the inner box body is provided with reinforcing ribs; the left upper end of the outer box body is provided with a water inlet valve; and the right lower end of the outer box body is provided with a water outlet valve. In the fluidic resistor device used for the high-voltage fluidic resistor soft start cabinet, which is disclosed by the invention, the size of the cabinet body is reduced, and starting frequencies are increased; since circulating water is adopted for cooling, cooling effects are better, fluidic resistor temperature is slowly raised when an electromotor is started, and the electromotor is frequently started; occupied space is reduced since the size of the cabinet is reduced; and cost is saved.

Description

technical field [0001] The invention belongs to the field of electric equipment, and more specifically relates to a liquid resistance device for a high-pressure liquid resistance soft starter cabinet. Background technique [0002] At present, the liquid resistance box of the high-voltage liquid resistance soft starter cabinet is made of a square box made of insulating material. Due to the thermal effect of the current, the heat generated during the motor starting process will cause the liquid resistance to heat up. In order not to prevent the temperature of the liquid resistance from being too high High, the size of the box will be increased when designing the liquid resistance box, which will make the appearance of the entire starter cabinet larger and occupy a larger space. Contents of the invention [0003] The object of the present invention is to provide a liquid resistance device for a high-pressure liquid resistance soft starter cabinet with small volume, small foot...
