Abstract
The utility model discloses a slip ring liquid motor starter, which relates to a liquid motor starter. The utility model aims to provide a slip ring liquid motor starter with the advantages of low cost, simple structure and no additional resistance liquid required. The technical proposal of the utility model is that the slip ring liquid motor starter comprises a liquid box, a polar plate and a contactor. The liquid box is divided into an upper cavity and a lower cavity by a polar plate which is arranged at the bottom of the liquid box. A self-priming pump is arranged at the lower cavity. A communicating pipe is arranged between the upper cavity and the outlet of the self-priming pump. Three polar plates arranged in the upper cavity are connected with the three-phase of the power, wherein, the middle polar plate is a vertical board and a profile board is arranged on each side thereof. The upper segment and the lower segment of the profile board are vertical plate. The distance from the lower segment to the middle polar plate is bigger than the distance from the lower segment to the middle polar plate. A skew plate is arranged between the lower end of the upper vertical plate and the upper end of the lower vertical plate. The utility model is used to be a slip ring liquid motor starter.
Description
Technical field:
The utility model relates to a kind of motor liquid starter, particularly a kind of liquid starter of slip ring electrical motor.
Background technology:
Existing motor liquid starter, diminish by the distance of pole plate between resistor fluid and to finish the purpose of little electric current actuating motor, and being moved, pole plate all adopt motor-driven machine driving, a reducing gear to finish, the shortcoming one of this structure is that mechanical transmission structure is complicated, the 2nd, the resistor fluid casing can not seal, and needs often to replenish resistor fluid.
Summary of the invention:
The purpose of this utility model provides a kind of liquid starter of slip ring electrical motor, the low and advantage that do not need to replenish resistor fluid of its cost simple in structure.The technical solution of the utility model is, a kind of liquid starter of slip ring electrical motor, comprise fluid box, pole plate and contactor, it is characterized in that: the fluid box bottom has a dividing plate that casing is divided into epicoele and cavity of resorption, self priming pump places cavity of resorption, between epicoele and the self priming pump outlet a connecting pipe is arranged, there are three pole plates to be connected with three of power supply respectively in the epicoele, middle plate wherein is a vertical plate, respectively there is a sketch plate its both sides, the epimere and the hypomere of this sketch plate are vertical plate, and the vertical plate of hypomere and the distance of middle plate are a swash plate greater than the distance of epimere vertical plate and middle plate between the upper end of the lower end of epimere vertical plate and hypomere vertical plate.Described resistor fluid is sodium acid carbonate and sodium chloride solution.The utility model is provided with special-shaped pole plate owing to be provided with a self priming pump be communicated with epicoele in the cavity of resorption of resistor fluid casing in the last sap cavity, thereby the utility model has simple in structure and the advantage of dead resistance liquid not compared with the prior art.
Description of drawings:
Accompanying drawing is a perspective view of the present utility model.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, bottom in the casing 1 has a dividing plate 7 that casing 1 is divided into epicoele and cavity of resorption, one self priming pump 8 is arranged at the bottom of cavity of resorption, between self-priming delivery side of pump and the epicoele a connecting pipe is arranged, being provided with three pole plates at the casing epicoele is connected with binding post on the casing respectively, middle plate 4 wherein is a vertical plate, respectively there is a special-shaped pole plate 2 its both sides, 5, the epimere of this abnormity pole plate is a vertical plate, the vertical plate of hypomere and the distance of middle plate be greater than the vertical plate of epimere and the distance of middle plate, left and right sides two-plate be up and down a swash plate between the vertical plate.On three binding posts on the casing and circuit that power supply A, B, C are connected, be provided with a contactor.
Starting principle of the present utility model is, resistor fluid is added in the fluid box, make resistor fluid be full of cavity of resorption, the liquid level of epicoele is behind the lower end of special-shaped pole plate swash plate, with casing 1 sealing, when actuating motor, turn-off contactor earlier, energized is opened self priming pump simultaneously, and in epicoele, liquid level 6 rises and reaches the top liquid level 3 of vertical section on the special-shaped pole plate at last with the resistance liquid pump in the cavity of resorption, distance between two parallel plate electrodes of this process and middle plate diminishes gradually, and the area of pole plate in resistor fluid increases gradually, and both make the resistance value ratio of initial resistance of electric motor starting and proceed-to-send big simultaneously, and the electric motor starting electric current generally is not more than 1.2 times.When liquid level is raised to the position of liquid level 3, finish electric motor starting, contactor conducting this moment, pole plate and power supply disconnect, self priming pump stops, and liquid is got back to cavity of resorption from epicoele through communicating pipe and self priming pump, finishes the starting of slip ring motor, resistor fluid is lossless, do not need to replenish resistor fluid, free from environmental pollution, simple in structure, volume is little, can be directly installed in the high-pressure electric control cabinet, realize high-voltage motor high and low pressure Comprehensive Control, easy to operate.
