    摘要: A mobile generator for generating a direct voltage for a tool supplied with direct current includes an alternating-voltage generator (1), an electronic control unit (3), a rectifier unit (2), which has a direct-voltage output (6) with live conductors (9, 10) for connecting the tool (11), and a protective device (14). The protective device is between the live conductors (9, 10) and a protective potential (18), especially ground or a protective wire. The protective device (14) has an insulating spark gap (15) responding in the case of an error with a defined response voltage (UT) for grounding the live conductors (9, 10).

    摘要: An electrical circuit protective arrangement in which a reed spring relay has provided a back contact probe element associated with one of the springs and makes contact therewith when the normally closed springs are open and presents a gap with the associated spring when the springs are closed. The springs are serially connected in the electrical circuit and are of a magnetically responsive material so that the springs are forced open when an undesirably high current is present in the circuit which in turn completes a detection and alarm circuit when the probe element makes contact with the spring. The relay envelope contains a gas which ionizes in the gap to complete the same detection and alarm circuit when a dangerously high voltage appears across the gap although the springs remain closed.

    摘要: Suitable for retail sales or contractor installation, this low-cost, multi-configurable five-part modular system protects sensitive equipment from lightning damage more completely than the limited ability of surge protectors, in homes, boats, offices and industrial applications. A wall outlet connected module can function by itself as a very capable lightning arrestor for 120 VAC power connected equipment. It also can provide protection to surge protectors as well as other modules, if employed. In the other system modules, an AC connected detector control module and three singularly optional accessory modules, permit advance warning, timed interrupt of AC power as well as coaxial or phone line connection control. Reacting to electromagnetic energy bursts up to approximately two miles away, only very local lightning causes system timer operation, avoiding unnecessary shutdown and resetting of equipment. The calibrated trigger range is adjustable down to approximately 1/2 mile and a manual reset feature allows restoring all equipment operation should a threat quickly pass.
