Problems solved by technology

[0002] Existing motor liquid starters achieve the purpose of starting the motor with a small current by reducing the distance between the pole plates between the resistance liquids, and the movement of the pole plates is completed by a mechanical transmission and a speed reduction mechanism driven by a motor. The disadvantage of this structure One is that the mechanical transmission structure is more complicated, and the other is that the resistance fluid box cannot be sealed, and the resistance fluid needs to be replenished frequently

Embodiment Construction

[0005] The present invention is described in detail in conjunction with the above accompanying drawings. There is a partition 7 in the bottom of the box body 1 to separate the box body 1 into an upper chamber and a lower chamber. There is a self-priming pump 8 at the bottom of the lower chamber. The outlet of the self-priming pump is connected to the upper chamber There is a connecting pipe between them, and three pole plates are arranged in the upper cavity of the box body to connect with the terminal posts on the box body respectively, wherein the middle pole plate 4 is a vertical plate, and there is a special-shaped pole plate 2, 5 on each side thereof, The upper section of the special-shaped pole plate is a vertical plate, the distance between the vertical plate of the lower section and the middle pole plate is greater than the distance between the vertical plate of the upper section and the middle pole plate, and an inclined plate is formed between the upper and lower verti...

Abstract

The invention comprises liquid tank, pole plate and contactor. The lower portion of the liquid tank has a separator used for separating the tank into an upper chamber and a lower chamber; the self-priming pump is located in the lower chamber; between the upper chamber and the outlet of the self-priming pump there is a communicating pipe; three pole plates in the upper chamber are respectively connected to the three phases, wherein the pole pale at middle portion is a stick up plate, and the two plates at both sides are sketch plates whose upper portion and lower portion shape the stick up plate; the distance between the lower portion of the side pole plate and the middle pole plate is more the one between the upper portion of the side pole plate and the middle pole plate; there is a slopping plate between the lower end of upper stick up plate and the upper end of the lower stick up plate.

Description

Technical field: [0001] The invention relates to a motor liquid starter, in particular to a slip ring motor liquid starter. Background technique: [0002] Existing motor liquid starters achieve the purpose of starting the motor with a small current by reducing the distance between the pole plates between the resistance liquids, and the movement of the pole plates is completed by a mechanical transmission and a speed reduction mechanism driven by a motor. The disadvantage of this structure One is that the mechanical transmission structure is relatively complicated, and the other is that the resistance fluid box cannot be sealed, and the resistance fluid needs to be replenished frequently. Invention content: [0003] The purpose of the present invention is to provide a liquid starter for slip ring motors, which has the advantages of simple structure, low cost and no need to replenish resistance liquid. The technical solution of the present invention is a liquid starter for ...
