Embodiment Construction

[0022] The present invention will be described in further detail below, but the embodiments of the present invention are not limited thereto.

[0023] Such as image 3 , 4 As shown, the wiring structure includes a line frame 400 and three line groups. The line frame 400 is located between the main unit 100 and the booster station 200, and is located between two cooling water towers 300. The three line groups are respectively connected to the main unit. 100 and the lead wire interface of the step-up station 200, each line group has three lead wires.

[0024] Such as figure 1 As shown, the line frame 400 includes a base frame, and the base frame includes two horizontal beams 420 arranged side by side and three pillars 410 arranged horizontally. In the middle part, a first wire channel 401 and a second wire channel 402 are sequentially formed between the pillars 410, and the width of the first wire channel 401 is greater than the width of the second wire channel 402. The top ...

Abstract

The invention relates to a line framework and a wire stringing structure. The line framework comprises a base frame, a first wire stringing channel and a second wire stringing channel which are arranged horizontally side by side are arranged on the base frame, a first wire stringing portion and a second wire stringing portion which are arranged vertically side by side are arranged in the first wire stringing channel, and the first wire stringing portion and the second wire stringing portion are each provided with three wire stringing points; a third wire stringing portion and a fourth wire stringing portion which are arranged vertically side by side are arranged in the second wire stringing channel, one of the third wire stringing portion and the fourth wire stringing portion is provided with two wire stringing points, and the other is provided with a wire stringing point. Two wire sets are installed on the wire stringing points of the first wire stringing portion and the second wire stringing portion respectively; one lead wire of another wire set is installed on the wire stringing point of the third wire stringing portion, and the other two lead wires of the wire set are installed on the wire stringing points of the fourth wire stringing portion. The floor area is small, wiring is convenient, and investment is little.

Description

technical field [0001] The invention belongs to the field of power transmission and distribution, and in particular relates to a line frame and a wire frame. Background technique [0002] Two outlets of two units in a power plant plus a backup power lead usually require a three-circuit overhead line to connect the main unit and the booster station. In order to save water, inland power plants mostly adopt the cooling method of circulating cooling water towers, and arrange the cooling water towers near row A of the main powerhouse to shorten the length of circulating water pipes. At this time, the three-circuit overhead line connecting the main plant building and the booster station is located between the cooling water towers. If the three-circuit line groups are arranged sequentially from top to bottom in the form of towers, the height difference of the conductors is too large, which will cause inconvenient connection and high cost. Therefore, a conventional three-circuit o...
