摘要: A circuit breaker is configured to be remotely caused to enter ON and OFF states. A lever arm is pivotably coupled to a main contact spring. A contact is supported at the distal end portion of the lever arm. Pivoting of the lever arm to bring the contact into contact with another contact on the housing causes the circuit breaker to enter the ON state. Pivoting of the lever arm to separate the contacts causes the circuit breaker to enter the OFF state. A latching solenoid includes a plunger coupled to the lever arm. The latching solenoid moves the plunger between a retracted configuration and an extended configuration. When in the extended position, the lever arm is pivoted to separate the contacts to cause the circuit breaker to enter the OFF state.

摘要: Position sensing modules associated with a device are provided. The position sensing modules are configured to receive electrical characteristics associated with one or more switches of a device over a predetermined period of time, the one or more switches being configured to connect service to or disconnect service from a customer; calculate a match indicator for each phase of the device including the one or more switches, the match indicator indicating whether an electrical characteristic on a load-side of the device matches a same electrical characteristic on a line-side of the device for each phase of the device; and determine a position of the one or more switches based on the received electrical characteristics and the calculated match indicator for each phase of the device.

摘要: Disclosed is a switch device that includes or is formed by a switchgear. Two sensors of the switchgear monitor two measured values and a switch of the switchgear is switched depending on these measured values. The adjustable thresholds for the measured values are displayed on a digital display integrated in the switchgear or arranged on an external input device. Both thresholds are adjusted digitally via the input device. The input device can be a commercially available smartphone with an app or a laptop.

摘要: A system for monitoring electric current in a network comprising at least one electrical fuse including a protective body, and at least one interrogating device arranged to interrogate at least one current sensing unit. The invention also concerns a method to monitor electric current in a network, including the steps of: determining a current in the electrical fuse, for example, via a voltage drop measurement across a fusible resistor in the electrical fuse; transmitting current determinations from the current sensing unit, for example, to a central management device; and processing received data from the at least one current sensing unit.

摘要: A rotary switch state detection device includes a magnetic field generating unit, a gravity sensing unit, a magnetic force sensing unit and a processing unit. The magnetic field generating unit generates a magnetic field. The magnetic force sensing unit and the gravity sensing unit are disposed at a rotary switch to detect a gravity value and a magnetic force value of the magnetic field and generate a gravity strength signal and magnetic field strength signal, respectively. The processing unit is connected to the gravity sensing unit and the magnetic force sensing unit to calculate a gravity value variation and a magnetic force value variation and thereby precisely locate a rotation head of the rotary switch upon completion of rotation thereof.

摘要: In a system for monitoring the operation of a current loop, which is fed by a current source and has a switching element, an evaluation unit is arranged at the output of the current loop, which evaluation unit is designed to identify a state of the switching element on the basis of the current flowing in the current loop. Furthermore, a signal generation device is arranged in the current loop, which signal generation device is connected to the switching element and is designed to generate a dynamic signal characterizing the state of the switching element in the current loop.

摘要: A communicating circuit breaker architecture with automatic load center position identification links circuit breakers having electronics for reporting a self-status signal including operating data and a position identifier. Each breaker has light pipes with optical ports at its sides for communicating with its neighbors and preferably a mechanically operated optical shunt providing an optical path through the breaker in the event of a trip. Each breaker has optical data transceivers for the light pipes which transmit self-status information through the light pipes and receive and repeat neighboring breaker status signals to its neighbors. The breakers form a network via their aligned optical ports reporting to an aggregator device in a known position of the Load Center which transmits breaker status reports outside the load center. Each breaker has a logic unit for determining its position in the load center based on the received position of a neighboring device.

摘要: An interface is disclosed for a self powered protection relay that uses mechanical switches for its configuration. The protection relay can include a base relay for measurement of line current and for generation of a trip signal, and a Human Machine Interface (HMI) unit for specifying, by a user, a base setting of an operating parameter of the protection relay. The base relay can be self-powered from the line and the HMI unit can include an auxiliary power supply. The protection relay is configured with mechanical switches provided in the protection relay. The HMI unit in the protection relay is designed to detect and alert the user of the relay of any change in the base setting carried out with one or more mechanical switches provided in the relay in powered and unpowered conditions of the base relay.
