Abstract
This invention provides a high power closing switch having a fast operating speed in the bypass of a main circuit switch for reducing the load share of the main circuit switch provided between a load coil and a power source circuit provided in a nuclear fusion reactor to simplify the construction of the main circuit switch formed heretofore of a number of parallel switches to reduce the value of the resistor of a clover circuit, thereby reducing the discharge current of the capacitor of the power source circuit.
Claims19
In a nuclear fusion reactor having a load coil, a power source comprising:
- a current source having a capacitor for supplying a rising current through a main circuit switch to said load coil for supplying a current to said load coil together with the current of said capacitor after starting discharging of said capacitor,
- a clover circuit having a series connection unit of a resistor and a diode for forming a circuit of an attenuating current flowed to said capacitor and said load coil upon completion of flowing the current of said current source,
- a contact unit having a tank sealed with compressed gas, a stationary contact, and a movable contact contained in the tank, and
- a closing switch having a control valve for controlling the opening and closing of said contact unit and an actuating valve for operating the movable contact in response to the operation of said control valve for bypassing said main circuit switch in high closing accuracy after a predetermined time from the start of discharging said capacitor,
In a nuclear fusion reactor having a load coil, a power source comprising:
- a first circuit having a rising capacitor connected through a first main switch with a clover diode and a load coil connected in parallel, and
- a second circuit having a PFN circuit connected with a second main switch,
- said first and second circuits being connected through a transformer, and
- a closing switch connected in parallel with a clover diode in said first circuit.
In a nuclear fusion reactor having a load coil, a power source comprising:
- at least one main switch for supplying current to said load coil;
- a capacitor coupled to said main switch for supplying a rising current through said main switch;
- means for supplying current to said load coil when the voltage of said capacitor equals a first value;
- and
- bypass means for selectively passing current which flows through said load coil around said main switch, said bypass means including a closing switch having a tank which is sealed with compressed gas and contains a stationary contact and a movable contact, a control valve which controls the opening and closing of said contacts, and an actuating valve which operates said movable contact in response to the operation of said control valve.
