Power circuit breaker and power resistor |
摘要 |
A compact power circuit breaker having a large breaking capacity and stable breaking performance by using a compact closing resistor unit having high performance. The power circuit breaker includes a main switch arranged in a current path, an auxiliary switch connected to the current path parallel with respect to the main switch and turned on prior to an ON state of the main switch, and a closing resistor unit connected in series with the auxiliary switch and incorporated with a resistor having a sintered body consisting of a Zn-Ti-Co-O-based oxide and having metal components consisting of titanium calculated as titanium oxide (TiO2) in an amount of 0.5 to 25 mol %, cobalt calculated as cobalt oxide (CoO) in an amount of 0.5 to 30 mol %, and Zn as substantially the balance.
