Embodiment 1

[0059] Such as figure 1 As shown, the top edge of the barrel of the insulating electrolyte tank 03 is provided with a circular convex edge, which can facilitate the hoisting and support of the barrel;

[0060] The outer wall of the insulating electrolyte tank 03 barrel is provided with multiple vertical reinforcing ribs, which can prevent the electrolyte contained in the barrel from being deformed due to excessive temperature;

[0061] The bottom of the insulating electrolyte tank 03 barrel is provided with a bottom plate, and the barrel and the bottom plate form a cavity structure with a closed bottom. There are multiple plate-shaped supports on the bottom plate, and the supports are arranged along the radial direction of the barrel. Processed water holes, the support is equipped with a limit plate, the outer edge of the limit plate is connected with the barrel, and the middle of the limit plate is processed with a mounting hole. The shape of the mounting hole can be determin...

Abstract

The invention belongs to the field of soft starting of a motor liquid, belongs to the technical field of a super-power slip frequency regulator of a vertical winding asynchronous electromotor, and in particular relates to an assembly pole plate of a super-power slip frequency regulator. The interior of an insulation electrolyte box is loaded with a liquid resistor, a fixed electrode assembly is arranged at a position, near to the bottom, of the insulation electrolyte box, a movable electrode assembly is arranged right above the fixed electrode assembly, an external driving device can be used for driving the movable electrode assembly to vertically move in the insulation electrolyte box, and the movable electrode assembly can downwards move to be contacted and matched with the fixed electrode assembly; during the descending process of the movable electrode assembly, a stator current of a motor is used as a judgment criterion for a descending speed of the movable electrode assembly, the larger the current difference value is, the faster the descending speed is, and the current difference value is a difference value between a stator current actual value and a stator current set value; during the rising process, the movable electrode assembly is lifted to a predetermined position before the motor discharges, so that impact current of the electromotor to a power grid is avoided; and the predetermined position is set generally according to the descending amplitude of a rotational speed of the electromotor caused by the discharge of the motor.

Description

technical field [0001] The invention belongs to the field of motor liquid soft starting, specifically belongs to the technical field of slip regulators for super-high-power vertical winding asynchronous motors, and specifically relates to an assembly polar plate of a super-high-power slip regulator. Background technique [0002] The traditional large and medium-sized wound asynchronous motors usually start with a slip regulator connected in series. [0003] In the use of slip products, the transmission motor drives the transmission mechanism to realize the automatic adjustment of the resistance value between the moving and fixed plates, so that the resistance changes from large to small and finally to zero, so that the motor can start smoothly without impact. [0004] The traditional large and medium-sized winding asynchronous motors usually start in a few tens of seconds, at most not more than one minute, and the supporting slip regulator products are disconnected through t...
