SOLUTION: An electrolyte 1 and electrodes 4, (5) dipped in the electrolyte 1 are accommodated in the inside of this resistor. A tank 2 equipped with a circular loop 23 in the outside and a blowing means 10 for air-cooling the circular loop 23 are installed. The electrolyte 1 in the tank 2 is introduced sequentially from the tank 2 into the circular loop 23 with a pump 8, cooled with the blowing means 10 during transfer in the circular loop 23 and returned to the tank 2 again.

Said compression chambers (4) are located between the electrodes (1) one behind the other and are configured by pressure-resistant insulating bodies (5; 11) and by partition walls (12) with connecting channels (81; 82; 83; 84) that are supported by said insulating bodies. The partition walls (12) are provided with a plurality of connecting channels (81 ... 84) that are not arranged in a cont Susipažinta. Skystinis rezistorius Japonija, H01C 10/02, patentas Nr.

SOLUTION: To suppress temperature rise of a resistor electrolyte 4 heated by electrification between a movable electrode 5 and a fixed electrode 6, the electrolyte 4 is sent to a cooler 8 by an electrolyte circulation pump 7. The electrolyte tank 1 does not have a closed structure as an operation Susipažinta. 2 lentelės tęsinys 1 2 3 4 5 rod 9 operated by an operation mechanism 10 is arranged. So it is not avoidable that a part of water content evaporates as a gas-liquid contact interface 2. Here, a floating ball 3 is provided on the gas-liquid contact interface 2 of the electrolyte tank 1. The floating ball 3 is such ball as the weight is adjusted to be submerged in the electrolyte by a half of its volume. The weight of the floating ball 3 is adjusted according to the composition of the electrolyte so that a half of its volume is submerged in the electrolyte.

Sato Hiroshi (JP) 4. 2001 05 25 5. 2002 12 06 PROBLEM TO BE SOLVED: To reduce rush currents by increasing the number of short-circuited stages in a starter for wound-rotor type motor using a liquid resistor. SOLUTION: The starter for wound-rotor type motor has the liquid resistor 2 which is connected with the secondary winding of a motor 1 and is so controlled that the resistance value thereof is lowered after start of the motor; resistors 5 which are connected in parallel with the liquid resistor 2 through switches 3 after the resistance of the liquid resistor 2 is minimized; and short- circuiting switches 4 for short- Susipažinta. 2 lentelės tęsinys 1 2 3 4 5 circuiting the secondary winding (short-circuiting resistors 5) of the motor after the short-circuiting resistors 5 are connected. The short-circuiting switches 4 are composed of a first switch 4uw and a second switch 4vw which are sequentially turned on, and a first interphase and a second interphase of the secondary winding of the motor are short-circuited one by one. When the first switch 4uv is turned on, the secondary-side resistance of the motor 1 becomes unbalanced but the number of short-circuited stages becomes two. As a result, rush currents which are produced during a period from the time when the movable electrode 2b of the liquid resistor 2 is brought into minimizing position to the time when short-circuiting is completed are reduced.
