Abstract

The invention relates to a linear dynamic resistor with gradually increased resistance value. The linear dynamic resistor is characterized by comprising an insulated container (G11), a conducting liquid (G31), a substance (G21), a bottom electrode (G51), an electrode bar (R50), a resistance layer (R51), an electromagnetic coil (G41), a first controlled path node (O+), a second controlled path node (O-), a first control end node (P+) and a second control end node (P-); and the linear dynamic resistor also comprises a bridge rectifier circuit (G60). A motor start-up buffer comprises the dynamic resistor. An electric power system comprises the dynamic resistor. The motor start-up buffer comprises the dynamic resistor. The electric power system comprises the dynamic resistor. The linear dynamic resistor is long in contactor service life, low in cost, good in isolation, and can be applied to high-power circuits such as weak current power circuits, electric power circuits and ultrahigh tension electric power circuits.
