摘要:
The invention relates to a terminal unit of a bus system (10), comprising a microprocessor (40) for generating an actuator command signal, a switching member (19) which is controlled by the actuator command signal and is used for switching a supply line (15) that contains a load (13), and a magnetically sensitive current sensor (35, 36) for detecting or measuring the current in the supply line (15). In order to create a terminal unit of a bus system (10), which features feedback for executing a switching command, is compact, and is not susceptible to interference, the supply line (15) is provided with a line section that is disposed on a circuit board (22) and has a forward line and return line (17, 18) to the switching member (19). Furthermore, the forward line (17) and the return line (18) are each fitted with a main strip conductor (30), at least one (30) of which encompasses a measuring section (31) that extends perpendicular to the main strip conductor. In addition, the current sensor (35, 36) is directed towards the measuring section (31, 31a) of the circuit board (22).
摘要:
An arc fault detector system (10) detects arcing faults in an electrical distribution system by monitoring one or more conductors (14) and producing an input signal representing one or more electrical signal conditions in the circuit (12) to be monitored. This input signal is processed to develop signals representing the electrical current flow through the monitored circuit (12) and broadband noise signal components. The system (10) analyzes these signals to determine whether an arcing fault is present, and if so, outputs a trip signal which may be used directly or indirectly to trip a circuit breaker or other circuit interruption device (44).

A remote operated relay is mountable in the panelboard in an adjacent pair of the load circuit positions comprising a multipole switching device, and a switch control for controlling the switching device, the switch control comprising a control circuit for operating the switching device responsive to control commands and a communication circuit for receiving control commands. An input/output (I/O) controller is mounted in the panelboard for controlling operation of the remote operated relay, the I/O controller comprising a programmed controller for generating the control commands for commanding operation of the remote operated relay, the control system including a communication circuit for communication with the remote operated relay communication circuit.
摘要:
The invention relates to a connecting system comprising an electromagnetic switchgear, especially contactor, and a connector. The aim of the invention is to provide a system which makes it easier to connect auxiliary and control lines. For this purpose, the connecting system comprises at least one electromagnetic switchgear (15), especially a contactor. Said switchgear (15) comprises a plurality of auxiliary contact connections (11) and a coil connection terminal block (2). Said coil connection terminal block (2) is configured in such a manner that the coil connections (11) lie in a plane (33) with at least one auxiliary contact connection (11). The connecting system also comprises a connector for simultaneously contacting the coil and auxiliary contact connections of one or more switchgears which connections lie in one plane. Said connector has an internal wiring for electrically interconnecting the coil and/or auxiliary contact connections.
