Abstract:
PROBLEM TO BE SOLVED: To improve a cooling efficiency of an outgoing generator line etc. by arranging a contact pressure means. SOLUTION: The cooling device relates to an electrical operating means, which has a cooling-target surface 12. The cooling device has a coolant, an outer wall the inside of which defines a volume 20 for the coolant, attachments 38 to secure the cooling device to the electrical operating means, and a contact pressure means 40. The outer wall is provided with a thermally conductive contact wall 32 having a contact surface 33 which is designed for a regional contact with the cooling-target surface 12. The contact pressure means 40 mechanically applies a prestress to the contact wall 32 to create a regional-contact pressure of the contact surface on the cooling-target surface, when the cooling device is attached to the electrical operating means.

PROBLEM TO BE SOLVED: To provide a method of diffusing a heat loss from an internal conductor and to provide a circuit breaker. SOLUTION: The circuit breaker (20R, 20S, and 20T) having elongated internal conductors (21R, 21S, and 21T) and outer conductors (22R, 22S, and 22T) like a housing has at least one heat pipe (1), extending from this inner conductor (21R, 21S, and 21T) to outer conductors (22R, 22S, and 22T) and having an insulating hollow object (5) for forming an electric insulating gap. This heat pipe (1) has a flexible deformable part (9). This heat pipe (1) can pass along the inside of a support insulator (24), which supports the inner conductor (21R, 21S, and 21T). In addition to a working medium, the heat pipe (1) contains an auxiliary gas which produces dielectric strength, strengthened at a low temperature. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
The present invention is concerned with the operation of a battery energy storage system (BESS) connected to an electric power system. The upper and lower state-of-charge (SoC) set-points of the BESS are adapted based on the analysis of the historical frequency data of the power system. A time dependent modulation function is determined for the upper and lower SoC set-points which avoids unwanted charging and discharging events.
Abstract:
A heat pipe (1) carries off heat-loss in an inner conductor (21) and extends from the inner conductor as far as an outer conductor (22). It also has an insulating hollow body (5) to form an electric insulating section (7). The heat pipe can run in an insulator (24) to support the inner conductor. An independent claim is also included for a method for cooling a heavy-duty circuit breaker's inner conductor stretched as an oblong and surrounded by an outer conductor in the form of a casing.
