摘要： The invention relates to a safety detection system comprising a detection chain formed by a number of interconnected safety detectors (D1, . . . D5). The detectors (D1, . . . D5) in the chain are also interconnected in order to form a diagnostic line in parallel with the safety chain. The first detector thus comprises means for generating diagnostic information comprising its surveillance state, and means for sending this diagnostic information, on the diagnostic line, to the second detector in the chain, which in turn enriches the diagnostic information. At the end of the chain, the last detector is connected to a diagnostic module (MD) intended to receive the diagnostic information, to interpret it, and to control the start-up of the application to be secured.

摘要： A safety circuit for disconnecting the power feed to an EV (electrical vehicle) charging enclosure or gasoline station fuel pump enclosure in the event that the enclosure is partially or totally dislodged from the foundation and dangerously high voltage has been exposed due to underground conduits being torn apart and electrical cables being exposed and in contact with sheet metal cabinets and other metal parts, thus creating the possibility of an explosion or the electrocution of a user or bystanders. The safety circuit comprises at least two proximity sensors, each of which transmits a signal into a control circuit which causes the power feed to the enclosure to be disconnected at the source when either or both of the proximity sensors inform the control circuit that the station has moved either vertically or horizontally more than a few thousandths of an inch.

摘要： A leakage current detection interrupter (LCDI) having open neutral detection. In one embodiment, the LCDI is formed in a plug and includes a circuit interrupter means for breaking a conductive path between line side phase and neutral conductors and load side phase and neutral conductors. A tripping means is coupled to operate the circuit interrupter means to break the conductive path upon the detection of the opening of the line side neutral conductor referred to as open neutral condition. The tripping means, which uses the neutral path as a return path if leakage current is detected, will, with this invention, use a line side ground conductor as a return path if the neutral path is broken anywhere between a service panel entrance and the plug. In response to the opening of the line side neutral conductor or leakage current, the LCDI interrupts the flow of current to a load such as a window air conditioner.

摘要： A power supply apparatus with a safety disconnect and a method of operating the power supply apparatus. A grounding sensor detects whether a frame ground of the power supply is connected to an external grounding point and shuts down output power if the frame ground terminal is not connected to the external grounding point. A neutral rectifier rectifies an output voltage of a voltage stabilizer and a voltage comparator outputs a non-grounding signal of a predetermined level if an output voltage of the neutral rectifier is lower than a predetermined criterion voltage. A switching part shuts down output power in response to the non-grounding signal.

摘要： A loss of neutral detector is disclosed. The detector includes a closed loop circuit which has a charge storage device, an output device and a switch in a normally-open position. The switch is controlled by a switch control circuit operatively connected to a loss of neutral detection circuit. The loss of neutral detection circuit detects an electro-magnetic field generated around the neutral lead on increase of the neutral potential via a pull-up resistor on loss of neutral. On detection of loss of neutral, the switch is closed so that the charge storage device energizes the closed loop circuit to activate the output device.
