The invention relates to the field of starters, and in particular to an electro-hydraulic rheostatic starter, which comprises a lifting mechanism, a first sealing mechanism, extending boxes, a container, an output mechanism, a liquid-adding mechanism, lower electrode plates, and a second sealing mechanism; the distance between each two electrode plates can be changed by the lifting mechanism, thesealing between the output mechanism on the top and the container is realized by the first sealing mechanism, the liquid-adding mechanism can automatically add liquid into the container, and the sealing between the lower electrode plates and the container is realized by the second sealing mechanism. According to the invention, since the sealing mechanisms are added for sealing at the joints between upper electrode plates, the lower electrode plates and the container, electrolyte inside can be effectively prevented from flowing out, the overall sealing property is increased, and the overall service life is prolonged; as resistance is changed, the upper electrode plates can be driven by a motor in a gear transmission manner to move upward, consequently, the stable rising and lowering of theelectrode plates is ensured, and resistance can be quickly changed.
Description
technical field [0001] The invention relates to the field of starters, in particular to an electro-hydraulic rheostat starter. Background technique [0002] The motor starter is a device used to assist the motor to start, so that the motor starts smoothly, has a small impact on the power grid, and can also realize soft parking, braking, overload and phase loss protection for the motor; it mainly includes liquid resistance starters , cage motor solid state soft starter, high-voltage cage motor starter; the working principle of the liquid resistance starter is to insert a specially prepared liquid resistance in series in the rotor circuit of the controlled wound motor, and adjust the concentration of the electrolyte and Change the distance between the two pole plates so that the resistance value of the liquid resistance always meets the requirements of the mechanical characteristics of the motor for the series resistance value during the starting process, so that the motor can...
