摘要： A box-shaped inner case (3) is accommodated in a box-shaped outer case (2), and refrigerant flow passages (27) are formed at five surfaces except an opening surface (24) by gaps between the inner and outer cases. A Gap of an opening edge of the outer case (2) and an opening edge of the inner case (3) is covered with a frame-shaped cover (6). A coil (4) is placed in the inner case (3), and the inner case (3) is filled with magnetic powder mixture resin so that the coil (4) except the terminals (4a, 4b) is embedded. A core (5) is made of the magnetic powder mixture resin. Cooling water flows along a longitudinal direction of the outer case (2) with one of refrigerant pipe connecters (15) being a refrigerant inlet and the other of the refrigerant pipe connecters (15) being a refrigerant outlet.

摘要： According to some embodiments, subsea fault tolerant transformer includes an arrangement of two tanks mounted one above the other. A lower tank houses the transformer windings and core and is below and abutting an upper tank. Both tanks are filled with respective dielectric oil. The electrical terminals for the primary and secondary power connections are on the second/instrument tank and the conductors pass through the instrument tank and then through the shared wall to the transformer tank. The design allows for enhanced cooling of the transformer through a single wall portion of the lower tank as well as fault tolerance associated with double barriers.

摘要： An electrical device for connecting to a high-voltage power grid has a boiler, which is filled with an insulating fluid and in which a magnetizable core and at least one winding, which surrounds a section of the core, are arranged, and a cooling system which includes at least one radiator which is arranged outside the boiler and is connected thereto via the radiator in order to circulate the insulating fluid, wherein the radiator has at least two heat exchange elements which are connected in parallel with one another. In order to enable a cold start to be accelerated and to be carried out even at relatively low temperatures only one of the heat exchange elements has a heat-conducting connection, as a heated heat exchange element, to a heat source which generates heat when the operation of the electrical device is started.

摘要： Systems and methods for liquid heat exchange for transformers are described. One embodiment of a fluid heat exchanger includes a transformer inlet port that is coupled to a transformer chamber and receives a dielectric fluid from the transformer chamber. Also included are a cooling fluid inlet for receiving a cooling fluid and a finned heat sink that includes a fluid communicator. The fluid communicator may receive, at a first chamber, the dielectric fluid from the transformer inlet port and directs the dielectric fluid across a first plurality of cooling fins. The fluid communicator may receive, at a second chamber, the cooling fluid from the cooling fluid inlet and may direct the cooling fluid across a second plurality of fins, where the fluid communicator separates the first chamber from the second chamber with a solid divider.

摘要： A device for detecting the level of the molten metal surface within a continuous casting mold. A detector element consisting of a body of a thermosensitive magnetic material, the magnetic properties of which vary in response to a temperature variation, is mounted at an appropriate position on a side wall of the continuous casting mold, and an electromagnetic coil for detecting the magnetic flux in the detector element is contained within a detector box mounted in a water jacket surrounding the mold at a position opposed to the detector element. The molten metal surface level within the mold is detected by detecting a change in the magnetic properties of the detector element by means of the electromagnetic coil. The detector box is detachably mounted in the water jacket, and water supply inlet and outlet means in the detector box guide cooling water through the detector box for cooling the electromagnetic coil within the detector box. A protective casing containing the electromagnetic coil is slidably mounted in a side wall of the detector box toward the mold for movement toward and away from the mold. The casing has an extension thereon projecting toward the mold and is spring-biased towards the mold, whereby a predetermined distance is maintained between the outer side wall of the mold and the protective casing.
