Title: Overhead electric line
Inventor: SHIMOKURA HISAYOSHI
IPC: H01B5/08
Filed: 1995-04-15
Abstract: PURPOSE:To provide an economical overhead electric wire with decreased wind pressure load. CONSTITUTION:Groove parts 3 having an arc-like cross section are formed in the surface sides of neighboring parts of segment element wires 1, which have a fan-like cross section and stranded in the outermost layer of an overhead electric line, to form spiral groove parts with an arc-like cross section in the outer circumference of the overhead electric line. As a result, when a wind strikes the overhead electric line and the boundary layer of an air current flowing the surface of the line passes the arc-like groove parts 3, the wind shifts the peeping point to the leeward side of the overhead electric line surface and thus wind pressure load is lowered.

Abstract: PURPOSE:To make a pressure in a perforated plate lower than an air core pressure by providing the perforated plate in a section between a cooling water inlet tube plate and a cooling tube support plate in the axial direction of a space on first and second cooling tube group side so as to surround the second cooling tube group. CONSTITUTION:In a section between a cooling water inlet tube plate 4 and a cooling tube support plate 10, a perforated plate 14 is provided in the axial direction of a space on first and second cooling tube group 9a and 9b side so as to surround the second cooling tube group 9b. Since the second cooling tube group 9b limited by the cooling water inlet tube plate 4 and the cooling tube support plate 10 is shielded by the perforated plate 14, an intermediate steam lane pressure around the second cooling tube group 9b performs again the function of an orifice by the perforated plate 14, that is, restricts a steam pressure in the inner surface of the second cooling tube group 9b, a pressure imbalance failure being able to be recovered. As a steam flow becomes smooth, the pressure of the perforated plate 14 is made lower than an air core pressure, an air trap generated mainly in the second cooling tube 9b group in the section between the cooling water inlet tube plate 4 and the cooling tube support plate 10 can be surely dissolved, heat transmission is accelerated and the capacity of a steam condenser is improved.
