Abstract
The utility model provides a high-pressure cage-type soft-starting device, which comprises a water tank, two static polar plates are arranged in parallel on the upper and the lower surface of the water tank. The utility model is characterized in that a rotating shaft is arranged between the two static polar plates in the water tank, two ends of the rotating shaft are connected with the water tank wall, a copper plate which can change the distance between the two static polar plates in the rotating process is fixed on the rotating shaft, a crank driving device which can make the rotating shaft to rotate makes the rotating shaft to connect with the shaft of the motor. Compared with the prior art, the utility model adopts the four-bar linkage to substitute for hoisting mechanism, the vertical movement of the hoisting mechanism is changed into the shaking of the rocker, as a result, the purpose of changing the distance of the polar plates is accomplished, the change of the flooding is finished, the space which is occupied by the mechanism is diminished, the integral structure of the device is reduced, and the cost is lowered.
Description
Affiliated field
The utility model belongs to the electric motor starting field, and what relate to specifically is a kind of high pressure cage modle electric machine soft starting device.
Background technology
High pressure cage modle soft starter device is by sealing in liquid resistance in the motor stator sub-loop, constantly reduce liquid resistance along with the rising of motor speed, when motor reaches rated speed, excise liquid resistance again, reaching the purpose of actuating motor.The variation of this liquid resistance is changed by mechanism action by the fluid box pole plate and realizes, is just changed the spacing of two-plate by mechanism, seals in stator resistance in circuit resistance thereby change.
Purpose, the mechanism that is used for high pressure cage modle soft starter device, change two-plate (12,13) spacing finishes (as shown in Figure 1) by a cover winding plant (11).Because this mechanism moves both vertically pole plate, then the stroke of pole plate motion has determined the size of equipment, yet the required liquid capacity of the liquid resistance of equipment itself is bigger, the tank-volumes that is carrying liquid is bigger, the shared volume of actuator of pole plate motion is also bigger, thus since, how to change the structure of equipment, thereby change bulky shortcoming, become the target of this equipment of improvement.
Technology contents
In order to solve the weak point that prior art exists, the utility model provides that a kind of overall structure is little, the high pressure cage modle soft starter device of low cost of manufacture.
For achieving the goal, the utility model provides following technical solution:
A kind of high pressure cage modle soft starter device, comprise water tank, water tank is upper and lower to be arranged with two static plate electrodes in parallel, it is characterized in that: be provided with a rotating shaft between two static plate electrodes in the water tank, the rotating shaft two ends are connected on the water tank wall, be fixed with in the rotating shaft can in rotation, change and two static plate electrodes between the plate shape conductor of distance, the transmission mechanism that rotating shaft is rotated links together rotating shaft and motor shaft.
Feature of the present utility model is that also described conductor is copper coin, coil pipe, grid, circular slab or elliptical flat-plate.
Feature of the present utility model is that also described transmission mechanism is a crank driving mechanism, and this mechanism is the quadric chain that is made of the connecting rod that is connected crank on the power transmission shaft and connecting crank and rotating shaft.
The utility model is compared with prior art, owing to adopt quadric chain to replace hoisting mechanism, change the shaking that move both vertically of hoisting mechanism for rocking bar, thereby reach the purpose that changes polar plate spacing, finish the variation of liquid resistance, make mechanism take up space and diminish, and make equipment overall structure dwindle that cost reduces.
Description of drawings
Fig. 1 is a winding type high pressure cage modle soft starter device structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 2, between the static plate electrode 1,2 of two parallel placements in water tank 8 rotating shaft 4 is installed, rotating shaft 4 and static plate electrode 1,2 parallel installations.Be fixed with conductive copper plate 3 in the rotating shaft 4, the quadric chain that is made of the connecting rod 5,7 that is connected crank 6 on the power transmission shaft and connecting crank 6 and rotating shaft 4 links together rotating shaft 4 and motor.
Motor rotates and drives the crank driving mechanism rotation, and rotating shaft 4 and steel plate 3 also rotate together, thereby can change the distance of steel plate 3 and static plate electrode 1,2, to reach the purpose that changes resistance.
