The safety circuit (10) is disposed for discharging a capacitor arrangement comprising at least one capacitor (19) that is associated with an electrical operating means (11). The at least one capacitor (19) is discharged, in a defined manner, via the safety circuit (10) through an electrical discharge circuit (33) during a discharge time period (ET), after a supply voltage (UV) on a power supply input (13) is switched off. At the end of the discharge time duration (ET), the electrical charge or the electrical energy of the at least one capacitor (19) is sufficiently low, so that an ignition of the potentially explosive atmosphere in the environment of the explosion-proof casing (12) is precluded.

  • Patent number: 8810081
    Abstract: An interlock arrangement allows a floating neutral electrical generator having a receptacle, such as a duplex receptacle, absent GFCI protection to be used to provide electrical power to the electrical system of a home or other building during utility power interruption. The interlock arrangement includes structure to disable or prevent access to the duplex receptacle when the electrical generator is coupled to the power cord used to transfer electrical power from the generator to the electrical system of the building. Thus, the duplex receptacles cannot be used to power electrical devices when the generator is connected to supply power to the electrical system of the building. Conversely, when the generator is physically disconnected from the electrical system of the building, the interlock arrangement exposes or supplies power to the duplex receptacles, and may be configured to close access to the receptacle used for connecting to a building electrical system.

    Abstract: An electrical disconnect assembly with separate disconnecting device compartment, such that safety handle mechanism does not provide access to the disconnecting device or any energized parts or conductors consisting of multiple compartments arranged so as to allow service of the load compartment without exposure to line voltages. The assembly includes a plurality of compartments with the load compartment having a lockable handle operator that that is interlocked with its corresponding compartment door. The handle operators are mechanically connected to the disconnecting devices via flexible cables or mechanical linkage. A key feature/distinction of this invention is that the disconnecting devices is remote mounted from the overcurrent protective device, so that when the handle operator is switched to the OFF position there are no components (e.g. disconnecting device and/or its conductors) within the load compartment that remain energized by line voltage.

  • Patent number: 8330304
    Abstract: An information handling system component contained within an information handling system housing uses the information handling system housing as at least a portion of a safety enclosure for hazardous functions of the component. A lock out device disables the hazardous function if the information handling system housing is moved relative to the component. For example, an optical disc drive laser is disabled if a Hall effect sensor in the chassis of the optical disc drive no longer senses a magnet placed in a portion of the information handling system housing used to enclose the optical disc drive. Alternatively, the component couples to the information handling system housing to enclose the hazardous function within the interior of the information handling system housing so that the component is inaccessible from the exterior of the housing.

  • Publication number: 20120249014
    Abstract: An electric-shock protection circuit that incorporates a PWM start-up control circuit for controlling the start-up of the PWM controller IC. When an electric-shock current test is conducted, the PWM start-up control circuit prevents the starting up of this PWM controller IC. This circuit is realized by resistors, capacitors and switches. In order to achieve protection, the switches perform an operation that different electric paths are activated for a supply voltage condition of around 90-149Vac and another condition of around 150-264Vac. The circuit disclosed in this invention: can be used in the electric-shock current test with a wide range of supply voltage; can ensure that the peak value of the shock current is lower than the safety threshold for human bodies; and can solve the problem encountered in carrying out the test of Standard UL935 where one end of the LED light tube is connected to the electric grid.
