徴とする可変抵抗器に関するものである。Furthermore, in general, in electrolysis performed under a large current, if the large current is changed all at once, the arc contact will be severely worn out, so it is required to increase or decrease the current in stages. In such cases, the use of a variable resistor can be considered. Conventionally, a grid resistor and a changeover switch or a water resistor have been used as a large-capacity variable resistor, but water resistors are not suitable for devices with low voltages and large currents, and grid resistors are generally The element is 200 ampf5
Since the current-carrying capacity is about 100 amps, in order to carry a large current of tens of thousands of amperes and create a desired resistance, it is necessary to connect many grid resistors in series and parallel, and the conductors connecting the resistors are also complicated. However, the overall size becomes very large, and in electrolysis under a large current of hundreds of thousands of amperes or more, such as salt electrolysis, there is a problem in that the amount of heat generated is large and a large cooling device is required. The present invention has been made in view of the above problems, and has been made to provide a variable resistor that can increase or decrease the current of an electrolytic cell in stages with a relatively small device. be. The present invention provides a plurality of resistors formed in a tubular body through which cooling water flows, a single-digit resistor terminal provided at both ends of each resistor, and a resistor terminal provided at one end of each resistor. and connection terminals in which each resistor is connected in parallel via the resistor terminal and the switch, and the connection is made by opening and closing the switches one by one. The present invention relates to a variable resistor characterized in that the current of a device to which it is connected can be increased or decreased stepwise by means of a variable resistor.
