摘要： A state grasp device that needs no optical adjustment, and can be downsized. An exciting current waveform of an opening electromagnetic coil of an electromagnetic operating set functioning to drive a moving contact of a switching device includes an inflection point appearing subsequently to a maximum value, the inflection point taking place at the time of the contact being parted. Accordingly, a wear amount of contact from the change over time can be obtained. A position of the inflection point is obtained, for example, by focusing the rate of change in current; and a wear amount of a switching contact is obtained from the change over time of a time when the inflection point takes place. With the device, the use of a mechanical detection device, such as an optical detector, can be eliminated.

摘要： An electronic trip unit having a two-wire, asynchronous, serial communication accessory network that is connected to a number of unique digital and analog remote slave devices. The address for each slave device is set by its function so that the trip unit does not have to be programmed in the field each time an accessory is added to the system. The network is capable of two-way communication when requested by the electronic trip unit. Accessory network communication is controlled by a first microprocessor within the electronic trip unit or alternatively by a network interface gateway. The first microprocessor controls voltage based and metering functions while a second microprocessor controls overcurrent and instantaneous protection functions of the trip unit. The second microprocessor also has the capability of communicating with a central control network.

摘要： An electric wire protection device includes a voltage adjuster that adjusts voltage on a power source side to be supplied to a load and a controller that includes a temperature calculation part which calculates temperature information of an electric wire based on a current value flowing through the voltage adjuster. The controller sets a first time constant as a time constant used to calculate the temperature information while the voltage adjuster is in the interrupted state, and sets a second time constant as a time constant used to calculate the temperature information while the voltage adjuster supplies power to the load. The first time constant is a value larger than the second time constant and equal to or larger than an actual time constant of the electric wire, and the second time constant is a value smaller than the actual time constant of the electric wire.
