System And Method For De-Icing Conductive Objects Utilizing At Least One Variable Resistance Conductor With High Frequency Excitation

Номер: US20130092678A1
Автор: Charles R. Sullivan, Victor F. Petrenko
Принадлежит: Dartmouth College

A conductor of a power transmission line has its effective resistance to flow of direct current or low-frequency current (such as, for example, 50 Hz or 60 Hz) varied in a wide range to pass current and/or to generate heat for melting ice. Increasing the initial resistance of a conductor is accomplished by modulating the current at a high frequency (HF), such as about 1 kHz to about 100 kHz. The current through the conductor then becomes a mixture of a DC (or low-frequency current) and a high-frequency current. Because the latter flows in a thin skin-layer region of the conductor of depth dependent on frequency, the conductor's resistance to the HF current is higher than its resistance value for low frequency or DC current. By varying the frequency of current modulation in accordance with the present invention, the conductor's resistance is adjusted to a desired value for ice removal.

A method of mitigating self-actuation of a switch may comprise generating a tracking signal, based on an input signal that the switch is configured to convey, and combining the tracking signal with an actuating signal to generate a modified actuating signal. The actuating signal may be configured to change a state of the switch from a first state (e.g., ON) to a second state (e.g., OFF). The method further comprises selectively applying the modified actuating signal to a gate of the switch. A switch self-actuation mitigation system may comprise a first coupling device for electrically couple an AC component of a first signal to a node, where the first signal is applied a switch input. The system may further comprise a second coupling device configured to electrically couple an actuating signal to the node, and a driving device configured to selectively couple the node to a gate of the switch.

A fault detection device has a pair of power supply lines connected to a high voltage battery via power supply relays. Capacitors and inverters for driving a motor are disposed between the power supply lines. A controller in the fault detection device controls the inverters to discharge the capacitors at different times after the power supply from the battery to motor is stopped by switching OFF the power relays. The controller then determines whether the capacitor voltage has dropped after each capacitor is discharged. Based on the determination result of the voltage drop in each of the capacitors, the controller can determine whether the power supply relays or the capacitors are malfunctioning.

This disclosure relates to monitoring the condition of electrical/electronic switches over time by monitoring the impedance of the switch. The condition of switches can degrade as they age, which can reduce their performance and may ultimately lead to failure. In many applications, particularly high-voltage applications, the reliable operation of switches may be very important and failures can present a safety risk and cause costly unscheduled system downtime for repairs. It has been realised that as the condition of switches change, their impedance changes, so monitoring the impedance can give a good indication of the condition of the switch, enabling potential faults/failures to be identified early and acted upon pre-emptively. 1.

A method for detecting a latent failure mode in an electronic selector having an interface switch and at least two underlying switches includes tracking and counting each of the underlying switch's close/open status change counts in the context of tracking and counting the interface switch selection status change counts. The method continues by calculating the ratio of each underlying switch's close or open status change counts against the interface switch selection status change counts. By comparing these ratios from each underlying switch in respect to the interface switch selection status change counts, a set of new algorithms are formulated to detect an interface switch latent failure mode due to either one of the at least two underlying switches stuck to open or one of the at least two underlying switches chattering between close and open states at a relatively high frequency compared to the interface switch selection event. 1.

A smart sensor network for power grid health monitoring includes a plurality of spaced sensors that are magnetically coupled to the power transmission line to be monitored. The sensors include a signal injection unit and a signal sensing unit. As such, one of the sensors acts to inject, via its signal injection unit, a high frequency signal through the magnetic coupling into the power transmission line, while sensors on either side of the signal injecting sensor act to block the injected signal, which is then detected by the signal sensing unit of the injecting sensor, and is used to measure the impedance of the power transmission line segment being analyzed. Based on the difference between a pre-measured impedance of the power transmission line being monitored and the actual impedance value of the power transmission line being measured by the sensor, the health of the power line can be obtained. 1. A power transmission line monitoring system comprising:a first sensor magnetically coupled to the power transmission line, and configured to inject a high frequency signal therein via the magnetic coupling;a second sensor magnetically coupled to the power transmission line at a predetermined distance from one end of said first sensor, wherein said second sensor blocks said injected signal back toward said first sensor; anda third sensor magnetically coupled to the power transmission line at a predetermined distance from another end of said first sensor, wherein said third sensor blocks said injected signal back toward said first sensor;wherein said first sensor detects said blocked signals from said second and third sensors to determine an impedance of a segment of the power transmission line that is between said second and third sensors.2. The power transmission line monitoring system of claim 1 , wherein the impedance is determined in real-time.3.

A fail-safe circuit enables a switch to turn on/off according to a signal from an external device if a microcomputer that controls the turning on/off of the switch falls into an abnormal state and is reset, and if the power supply for a circuit that backs up the control of the switch is lost. The fail-safe circuit includes a microcomputer that controls the turning on/off of a switch based on an instruction signal from an input terminal, a watchdog circuit that generates a reset signal based on a watchdog pulse from the microcomputer, and a transistor for masking a watchdog pulse for resetting a flip-flop circuit that is set by the reset signal. If a voltage supplied by a power supply circuit is lost, a transistor turns off, and therefore the switch turns on/off according to an instruction signal supplied to an output terminal via a resistor and a diode. 1. A fail-safe circuit comprising a controller that controls a turning on/off of a switch based on and external instruction signal instructing a turning on/off of the switch , and a watchdog circuit that generates a reset signal for resetting the controller based on a watchdog pulse generated by the controller , the fail-safe circuit performing a fail-safe operation based on the reset signal generated by the watchdog circuit , the fail-safe circuit comprising:a flip-flop circuit that is respectively set and reset upon receiving the reset signal and the watchdog pulse; anda mask that masks the watchdog pulse that is to be input to the flip-flop circuit,wherein in a case of being reset by the reset signal, the controller masks the watchdog pulse using the mask from when the reset is released until starting to control a turning on/off of the switch, andin a case where the flip-flop circuit has been set by the reset signal, and in a case where a power supply for supplying power to the flip-flop circuit been turned off, the switch is turned on/off according to the instruction signal.2. The fail-safe circuit according to ...
