Description
Technical field
The utility model relates to the iron tower that erects power transmission lines, and particularly relates to a kind of 220kV of being applied to common-tower double-return road and directly bores the new tower of getting on the 500kV transmission line of electricity.
Background technology
At present, newly-built 220kV circuit is mostly with common-tower double-return Lu Weizhu, this iron tower comprises body of the tower, be connected in the straight-arm of body of the tower, be symmetricly set in the cross-arm of four layers of supporting structure parallel to each other of the layout double loop lead of straight-arm both sides, the four layer cross-arm downward from the straight-arm top are followed successively by the ground wire cross-arm, the upper conductor cross-arm, middle lead cross-arm, the lower wire cross-arm, the both sides, front and back of the bottom surface of every layer of cross-arm end all hang the traction insulator string of traction lead, hang hanging of traction insulator string on the cross-arm and locate the also corresponding vertically insulated string that the lead of drawing from the traction insulator string is hung in two downward being used to that is provided with, lead is to arrange with the overhang of lead self below cross-arm, promptly with the arranged in form of flexible jumper, wherein straight-arm and cross-arm are called the tower head of iron tower, because the lead of this iron tower is a vertical arrangement, the tower head height of iron tower is higher, bore when getting over the 500kV circuit, bore and get over very difficulty of point selection, usually adopt the 220kV circuit to detour, rising 500kV circuit, two modes such as the part becomes single time, the above technical scheme complexity of returning of 220kV, may need power cut construction, difficulty of construction is big, investment is high, inconvenient operation maintenance.
Below when just boring more main mode illustrate respectively:
