摘要： A circuit breaker comprises a solid-state bidirectional switch, a switch control circuit, current and voltage sensors, and a processor. The solid-state bidirectional switch is connected between a line input terminal and a load output terminal of the circuit breaker, and configured to be placed in a switched-on state and a switched-off state. The switch control circuit control operation of the bidirectional switch. The current sensor is configured to sense a magnitude of current flowing in an electrical path between the line input and load output terminals and generate a current sense signal. The voltage sensor is configured to sense a magnitude of voltage on the electrical path and generate a voltage sense signal. The processor is configured to process the current and voltage sense signals to determine operational status information of the circuit breaker, a fault event, and power usage information of a load connected to the load output terminal.

摘要： Exemplary embodiments are directed to a direct current switching apparatus including at least a first mechanical switching device which is suitable to be positioned along an operating path of an associated DC circuit and includes a fixed contact and a corresponding movable contact which can be actuated between a closed position and an open position along the operating path, wherein an electric arc can ignite between the contacts under separation. The switching apparatus includes an electronic circuit having a semiconductor device which is suitable to be positioned along a secondary path and connected in parallel with the first mechanical switching device. The electronic circuit can be configured to commute the flow of current from the operating path to the secondary path and extinguish an electric arc ignited when the movable contact separates from the fixed contact when the first mechanical switching device fails to extinguish the same.

摘要： A high voltage direct current (HVDC) hybrid circuit breaker is provided. The circuit breaker includes a solid-state main breaker, a mechanical fast disconnector and a solid-state auxiliary breaker connected in series, the series-connection of the disconnector and the auxiliary breaker being connected in parallel to the main breaker, a snubber circuit including a capacitor, and a switching device being arranged for disconnecting the snubber capacitor in response to the auxiliary breaker being opened. By disconnecting the snubber capacitor, an uncontrolled discharging of the capacitor through the disconnector and the main breaker, and the resulting non-zero current flowing through the disconnector during the breaking action, may be avoided. Further, a method of an HVDC hybrid circuit breaker is provided.

摘要： An input voltage (UL) contacted at the input (2a) of a contact (2) can be through-connected to an output (2b) of the contact (2) or switched off via a movable contactor. In order to determine the switching state of the contact (2), any drop in the contact voltage between the input (2a) and the output (2b) is detected. By means of the detected contact voltage, it can at least be determined whether the input voltage (UL) has been through-connected to the output (2b) or switched off.

摘要： Circuits and methods are disclosed for suppressing arcing occurring in switch contacts that includes a triggerable electronic switch in parallel with a series connection of relay switches. The trigger electrode of the triggerable electronic switch is connected to a node between the series connected relay switches, which allows the electronic switch to be turned on to a conducting state when a voltage difference occurs between the node and either of the opposite ends of the switches. The voltage difference arises because of arcing that occurs when the relay switches bounce, typically during opening and closing of the relay switches. The opposite ends of the switches are connected to conduction terminals of the electronic switch, where the electronic switch carries substantially all of the current supplied to a load for a half-cycle or less of an AC current cycle when arcing occurs in the relay switches, thereby bypassing the relay switches and suppressing arcing therein.

摘要翻译：公开了用于抑制开关触点中发生的电弧和方法，其包括与中继开关的串联连接并联的可触发电子开关。可触发电子开关的触发电极连接到串联连接的继电器开关之间的节点，当节点与开关的相对端中的任一端之间出现电压差时，允许电子开关导通到导通状态。由于在继电器开关反弹时发生的电弧，通常在继电器开关的打开和关闭期间产生电压差。开关的相对端连接到电子开关的导电端子，其中当在继电器开关中发生电弧时，电子开关基本上承受提供给负载的半周或更短的交流电周期的电流，从而绕过继电器开关并抑制其中的电弧。
