Abstract

The invention belongs to the technical field of electrical cabinets, relates to a heat dissipation device for an SYQT intelligent dynamic liquid resistance speed regulator and a using method.An existing liquid resistor generates heat due to the fact that large current passes through the existing liquid resistor, and as a result, the electro-hydraulic temperature rises too high and too fast. The invention just aims to solve the above problem. According to the technical schemes of the invention, a plurality of resistance speed regulation cabinets are arranged; a heat dissipation plate is arranged on the surface of the front side of each resistance speed regulation cabinet; a short-circuit cabinet is arranged on one side of each resistance speed regulation cabinet; a control cabinet is arranged on the other side of each resistance speed regulation cabinet; a cooling tower is connected to the outer side of the top of each resistance speed regulation cabinet; and an alkali liquor storage box is arranged on the surface of the rear side of each resistance speed regulation cabinet. The cooling towers, plate heat exchangers and water pumps are arranged; the plate heat exchangers cool alkali liquor through cooling water; the used cooling water enters the cooling towers through the water pumps, so that the recycling of the cooling water is achieved; the cooling effect of the cooling towers is good, the cooling water is free of loss, and circulating cooling work can be conducted for a long time.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to a cooling device for a SYQT intelligent dynamic liquid resistance governor and a method for using it. Background technique [0002] At present, the commonly used liquid resistance starting cabinet is to connect the liquid resistance in series in the stator circuit of the star point of the motor. The resistance value of the liquid resistance is adjusted by adjusting the distance between the movable plate and the fixed plate, that is, the farther the distance between the two plates is, the greater the resistance value is, and the smaller the current passing through the liquid resistance and the motor winding is, the motor will The lower the rotation speed; the closer the distance between the two pole plates, the smaller the liquid resistance value, the greater the current passing through the liquid resistance and the motor winding, and the higher the motor speed, so as ...
