Abstract
A new protection system for capacitor banks in case of short-circuiting accident is described.<br>A pulsed power system, which is composed of many capacitor units and closing switches, is well known for producing a controlled pulse current of high power as for the power source of plasma experimental device, etc.. According to the increase of a capacity of bank system, it becomes important to protect the whole bank system from the accident of short-circuiting in a capacitor unit.<br>Although some protective ideas have been proposed, these conventional ideas have not been sufficient means to absorb the energy flowing into the failure unit from other normal units. Constructing the new 1 MJ capacitor bank for plasma experimental device, we designed a protective device of new conception. The new protection system, which is able to absorb the bank energy and to suppress the short-circuiting current flowing into the failure capacitor units, overcomes the defect in former protection systems. To confirm the utility of new protection system, we made a test of protection resistor imitating the actual bank circuit. Test result showed that absorvable energy for unit ceramic resistor amounted to 1500 joule/cc. The new system is adopted to the bank system of TPE-1RM15 plasma experimental device.
