20140035716 | Reflowable Circuit Protection Device - A circuit protection device includes a housing, which includes first and second electrodes. The device includes a conductive slider inside the housing. At a first location within the housing, the slider provides an electrical connection between the first and second electrodes. At a second location within the housing, the slider does not provide the electrical connection. A spring is secured to and stretched between the slider and an inner side of the housing such that the spring is held in tension in an expanded state. The slider is held at the first location by a solder between the slider and the first and second electrodes. After the device is armed, detection of an over-temperature condition causes the solder to begin to melt and the spring to compress and pull the slider to the second location within the housing, thus severing the electrical connection between the first and second electrodes. | 02-06-2014 |
20140091895 | DISCONNECTOR FOR ELECTRIC POWER EQUIPMENT FILLED WITH DIELECTRIC LIQUID - A disconnector for electric power equipment filled with dielectric liquid, especially transformers, applicable in protecting the operation of electric power equipment.

The disconnector is characterized in that the current-limiting fuses are placed in a common housing, in which a slide with a pilot is situated, and to the slide there are inseparably fixed moving contacts, which move together with the slide when the slide makes a to-and-fro motion. The to-and-fro motion takes place as a result of the operation of a tripping device situated in the current-limiting fuses and of the compression or stretching of springs fixed to the pilot and to a fixing disk. | 04-03-2014 |
