The invention discloses a rheostat structure of an electricalhydraulic rheostat starter. The rheostat structure comprises a water tank, three pairs of electrode bars and an electrode bar lifting structure. The rheostat structure further comprises two locating columns, a buoy and a flexible indication strip, wherein the locating columns are fixed into the water tank; the buoy is arranged on ...
A rheostat is a variable resistor which is used to control the current flowing in a circuit. Types of Rheostats. Several types of rheostats exist. The rotary type is the most commonly used in power control applications. Most of the time these rheostats use an open construction, but enclosed types are also available. Just as with potentiometers ...

The EPM rotor starter is normally used to control the starting of a slipring motor, and the starting current is generally limited to a maximum of 250% FLC. Optimal starting torque for each application is normally selected by the choice of the initial value of resistance. The principle of the EPM starter is that the
A twin drive rheostat is then indicated. The PIONEER type LRS x 2 rheostat ensures identical acceleration of both motors. The moving carriages are mechanically coupled and driven by single servo mounted on common frame are used. In this case the ohmic resistances of the electrolyte of the two tanks are equalized through interconnections between

Rheostat is a variable resistor, which is used to control the flow of electric current by manually increasing or decreasing the resistance. The English scientist Sir Charles Wheatstone coined the word rheostat, it is derived from the Greek word "rheos" and "statis" which means a stream controlling device or a current controlling device.
The term rheostat was coined by the English scientist Sir Charles Wheatstone and is derived from the Greek word "rheos" and "statis" which means current controlling device. Rheostat Symbol There are two rheostat symbols that are available, and they are the American standard and the international standard.

I haven't worked on liquid rheostat starters for almost 50 years. We were starting pairs of 3000 HP motors at 13,000 Volts. Once the shorting contactor closed the rheostat contactor opened. There were six pairs of motors and three liquid rheostats. (One spare.) A large contactor panel allowed any rheostat to be connected to any motor for starting.

A rheostat is a type of variable resistor. When placed into an electrical circuit, a rheostat can be used to adjust and control the amount of current flowing around it. They do this by varying the resistance on the circuit, without interrupting the supply of power. Rheostats are one common type of electromechanical variable resistor.
Caution: The hand crank is only to be actuated if the starter is free of voltage Liquid Rheostat Type Page 4 AFA(K/P) | DAFA(K/P) | SFA(K/P) Liquid starter with regulation and servo drive (SFA, SFAK, SFAP starters) The setting drive is a compact servodrive regulator with and special control unit.
The starter has movable plates rather than relieing on heating to change the resistance. When starting the motor the operator monitors the stator current and manually controls the starter, keeping the stator current just below the motor protection pick up point. ...
