摘要： An electrical circuit interrupter includes a primary or normal current carrying path and a transient or alternative current carrying path. The normal current carrying path is established by a movable spanner extending between stationary contacts during normal operation. The transient current carrying path includes at least one variable resistance element which transitions from a lower resistance to a higher resistance during interruption. The transient current carrying path forms an open circuit in parallel with the normal current carrying path during normal operation. Upon interruption, the transient current carrying path is favored for the fault current, completely interrupting the normal current carrying path. The variable resistance elements increase their resistivity during this phase of operation to aid in providing high levels of back-EMF for complete interruption of fault current through the device and limitation of let-through energy.

摘要： A current limiting device utilizing an electrically conductive composite material and an inhomogeneous distribution of resistance structure is disclosed. The inhomogeneous distribution is typically chosen so that at least one selected thin layer of the current limiting device has much higher resistance than the rest of the current limiting device. In the actual device, pressure is typically exerted on the composite material in a direction normal to the selected thin layer. During a short-circuit, it is believed that adiabatic resistive heating of this selected thin layer is followed by rapid thermal expansion which leads to either a partial or complete physical separation of the current limiting device at the selected thin layer which produces a higher over-all device resistance to electric current flow. Thus the current limiting device limits the flow of current through the short-circuited current path. When the short-circuit is cleared, the current limiting device regains its low resistance state allowing electrical current to flow normally. The current limiting of the present invention is reusable for many such short circuit conditions.

摘要： A circuit interrupter is provided with a parallel-connected resistor which is cooled to a temperature of from 4* K to 80* K, but higher than the critical temperature of the resistance material. The resistor is connected in parallel with the circuit interrupter contacts at either an arbitrary time or just prior to a current zero value. The heating of the resistor during currentlimiting operation increases its resistivity by about 100 times.

摘要： A charging protection and regulation device includes a matrix of Positive Temperature Coefficient (PTC) devices having multiple legs each including one or more PTC devices, a matrix of diodes having multiple legs and multiple types of diodes having different voltage drops, and a matrix of resistors having multiple legs each including a current limiting resistor. Each PTC device is thermally coupled to an ambient environment using a different amount of thermal coupling. Respective legs of the matrix of PTC devices, matrix of diodes, and matrix of resistors are electrically coupled together, and coupled to one or more electron storage devices. During conditions of overload or circuit fault, the PTC devices act as high resistance circuit interrupters. During conditions of light loading between input and output terminals, the different voltage drops across the diodes provide voltage regulation/current regulation such that a specified charge voltage is provided to electron storage devices.

摘要： In a direct current cutoff switch1, a PTC 5, which is a non-linear resistor, is parallel connected to a contact circuit composed of a fixed contact 4-2 and a movable contact 8-2 via electrodes 5-1. When the switch is closed, no current flows in the PTC 5 with a prescribed resistance value at 25° C., since voltage between both the electrodes 5-1 is almost “0”. When the switch is opened in order to cut off current, the contacts form a closed circuit since the PTC 5 is parallel inserted between the fixed contact 4-2 and the movable contact 8-2. For this reason, it is difficult for surge voltage to occur and an arc hardly occurs between both the contacts. The PTC 5 instantaneously heats due to passing current, reduces the resistance value and passes peak current. Then, the resistance value rises and becomes stable in a high value such that weak current which is negligible at 42V, which is rated voltage. Thus, current is substantially cut off.

摘要翻译： 在直流截止开关1中，作为非线性电阻器的PTC5经由电极5-1与由固定触头4-2和可动触点8-2构成的接触电路并联连接。 当开关闭合时，由于电极5-1之间的电压几乎为“0”，所以在25℃下没有电流以规定的电阻值流过PTC 5。 当开关为了截止电流而断开时，由于PTC 5平行地插入在固定触点4-2和可动触头8-2之间，所以触点形成闭合电路。 因此，在两个触点之间难以产生浪涌电压并且几乎不发生电弧。 PTC 5由于通过电流而瞬间加热，降低电阻值并通过峰值电流。 然后，电阻值上升并稳定在高值，使得在42V下可忽略的弱电流为额定电压。 因此，电流基本上被切断。

摘要： A Positive Temperature Coefficient Resistivity (PTC) element has a resistivity that increases as the temperature increases. Circuit breakers having PTC elements can achieve better overload and short circuit protection than existing products. Breakers with PTC elements can also be combined with ground fault detection circuits to activate the circuit breaker under ground fault conditions that are less severe than the overcurrent conditions that would normally activate the circuit breaker. A shunt trip assembly incorporating a PTC resistor reduces the required power rating of the clearing switch.
