摘要： An electric-wire protection device includes a voltage adjustment unit that adjusts the voltage to a load, and a controller that includes a temperature calculation unit that calculates temperature information on an electric wire from a value of current, and makes the voltage adjustment unit into a shut-off state based on the temperature information. The temperature information is calculated from an amount of temperature changes based on the current value and a predetermined initial value. The controller shifts into a sleep state when a sleep condition is satisfied that includes a condition that the temperature information is lower than the initial value. The initial value when the controller returns from the sleep state is based on a convergence value of temperature in conducting energization on the electric wire at a maximum value of steady-state current.

摘要： A circuit breaker includes first and second terminals, separable contacts, conductors electrically connecting the contacts between the terminals, and an operating mechanism to open and close the contacts. A current sensor senses current flowing through the contacts and outputs a current value. A number of temperature sensors output a number of temperature values corresponding to a number of the conductors. An electronic trip circuit cooperates with the operating mechanism to trip open the contacts, and includes a processor having a first input inputting the current value, a first routine inputting the current value from the first input and causing the operating mechanism to trip open the contacts responsive to over-current, a number of second inputs inputting the number of temperature values, and a second routine comparing the number of temperature values to a number of limits and causing the operating mechanism to trip open the contacts responsive to over-temperature.

摘要： An automatic temperature compensation method that automatically adjusts trip point thresholds of a motor circuit protector in response to changes in temperature. The relationship between two curves is exploited to match temperature sensor readings from a temperature sensor circuit with burden resistor percentage values derived from a burden resistor circuit. A temperature inflection point is determined from the intersection of (1) the temperature sensor curve plotting the voltage output of the temperature sensor versus temperature and (2) the burden resistance curve plotting burden resistance versus temperature. A temperature value along the temperature sensor curve is transformed into the corresponding burden resistance on the burden resistance curve. The burden resistance is expressed as a percentage variance from a burden resistance at an ambient temperature. An adjusted trip point threshold is calculated from the computed burden resistor percentage, and the adjusted trip point threshold is stored in a memory.

摘要： An electronic trip unit having two microprocessors one of which monitors the load voltage and current within the normal operating range and performs the metering and delayed trip algorithms associated with that range. A second microprocessor monitors the load current for excursions outside the normal operating range and processes those algorithms and functions associated with the instantaneous and overcurrent trip protection modes of the trip unit. Each microprocessor receives inputs representative of the monitored current that are scaled to a different factor corresponding to the range the microprocessors are assigned to monitor. In one embodiment the electronic trip unit is controlled by a master controller and in turn controls a number of accessory devices, wherein one of the microprocessors is a slave to the master controller network and the other microprocessor is a master to the accessory slave network. The microprocessors communicate with each other and either one can trip the circuit on detection of a fault condition.
