| PROBLEM TO BE SOLVED: To provide a switch which safely shuts off a large DC current at a high voltage without fusing or damaging a contact with a small configuration. SOLUTION: A DC current cut-off switch 1 has a PTC 5 connected as a nonlinear resistance element in parallel with a contact circuit formed of a fixed contact 4-2 and a movable contact 8-2 via an electrode 5-1. A voltage between both the electrodes 5 and 1 is substantially "0" at the PTC 5 having a predetermined resistance value at 25°C as a reference when the switch is closed, and current does not flow. When the switch is opened to shut off the current between the contacts, the contact section becomes a switching passage via the PTC 5 connected in parallel between the fixed contact 4-2 and the movable contacts8-2 so that a surge current hardly occurs, and an arc hardly occurs between both the opened contacts. The PTC 5 is heated instantaneously by the passing current to lower its resistance value. After a peak current flows, the resistance value is raised, the PTC 5 is stabilized at a high resistance value for passing an infinitesimal current of the degree to be ignored at 42V of a rated voltage, and the current is substantially shut off.

| (57)【要約】 故障電流遮断器が、１対の開離し得る接点の間に接続された重合体限流器及び電圧依存性抵抗の並列の組合せを設けることによって構成されて、接点が最初に開離されるときに接点間にアークを発生させずに電流を遮断することが出来るようにする。 重合体限流器は、休止動作電流で比較的低い抵抗値を持つと共に、短絡過電流で実質的に一層高い抵抗値を持つように選ばれる。 これによって、電流が接点から重合体限流器を通るように切換えられ、次いで電圧依存性抵抗の両端間の電圧が該電圧依存性抵抗を導電性にする電圧になったとき、電流は重合体限流器から切換えられるようになる。 | ||||||

| PROBLEM TO BE SOLVED: To delay the operation of one switch properly and at an approximately constant delay time, and change the delay speed thereof easily and without any contamination, regarding a delay switch capable of lessening rush current, for example, to an electric motor or the like via the change of the activation timing of two switch mechanisms.

| PURPOSE: To reduce a contact load caused by an arc and to limit a transient branch current irrespective of an arc extinction device by having a branch conductor for electrically receiving a set of fixed and movable contacts, one arc extinction chamber and an end of the arc. CONSTITUTION: When a contact is closed, a small current I passes through a path C1 including a movable part 12, contacts 12a and 11a, an end 11b of a fixed part 11 and a connection part 11c of the fixed part 11, and flows between terminals 13 and 14. When a device 17 is operated, a conducting part 12 is lifted and the contact 11a is separated from the contact 12a. An arc A1 occurs between these contacts. When a contact spacing exceeds a distance (e) between a fixed surface 21a and a movable surface 18a which are opposite to each other, the arc A1 is changed to an intermediate arc A2. Plasma is produced in a gap having a width (e), and the occurrence and continuation of the arc A2 are facilitated to reduce the load and abrasion of the contacts. At this time, a current passes through a path C2, and flows between the terminals 13 and 14. In addition, the current flows through a resistor having a positive coefficient, and is immediately limited when it exceeds a bending point of resistor characteristics.

| PURPOSE: To open a breaker without generating arc or voltage break by changing the direction of a load current from the breaker before the breaker is opened. CONSTITUTION: A control impedance composed of a saturable reactor 15 is connected to a breaker 14 in series to form a circuit network to pass a load current. Pulse forming circuits 36, 38 are connected between both ends of the circuit network. When the electric current must be broken, with the application of a pulse at a reverse direction to the load current to the circuit network, the saturable reactor 15 is switched from a low impedance state to a high impedance state to make the current of the circuit network small sufficiently and then the breaker contact is opened.
