Abstract

The utility model discloses a wire arrangement mode converting rod comprising a top cross arm. The top cross arm is arranged on the top of a wire pole and is connected with the wire pole vertically. Using the wire pole as a center, the top cross arm is bilaterally symmetrical. The left end and the right end of the top cross arm are equipped with three insulators used for being connected with wires, respectively. A bottom cross arm vertically connected with the wire pole is arranged under the top cross arm and is arranged on the right side of the wire pole. Three insulators used for being connected with wires are disposed on the bottom cross arm. The wire arrangement mode converting rod has characteristics of simple structure, convenient and attractive line connection, and low production cost.

Description

A kind of arrangement of conductor selector bar
Technical field
The utility model relates to a kind of arrangement of conductor selector bar.
Background technology
The power supply in city is to realize with the form of supply network, the general 10kV electric pressure ,Mei Tiao street that adopts is all by a circuit, in order to save the electric power corridor, the general erection mode that adopts same tower (bar) double back of overhead transmission line, supply network is formed by connecting by the supply line of each block.If there is the user to connect general needs whole block power failure when drawing 10kV branch from basic routing line, interruption duration is generally 2-4 hour, power failure range is a block, between two block switches, State Grid Corporation of China is in order to improve power supply reliability, reduce interruption duration, serve better society, proposed the mode of live line working.The overhead transmission line of existing upper and lower double back, under can carry out smoothly when coming live line working, be subject to winding displacement road in the impact on lower winding displacement road can not implement live line working.The line live-line work of left and right double back can carry out, unaffected.In order to facilitate charged connecing to draw, newly-built overhead transmission line all adopts the left and right arrangement mode, and newly-built circuit also needs to be incorporated to supply network, with the connection in original electrical network.Tie point is all at crossing.Newly-built circuit from the contact of original circuit the time because arrangement mode different, the general cable that adopts connects, need to found two circuit terminations each base of cable termination shape steel tube bar, the cable of finally planning the trunk cable according to urban distribution network adopts 300mm or 400mm copper conductor cable, require and do not affect the principle of urban highway traffic according to urban planning, the non-excavation of the sure employing of passing by one's way top (trombone slide mode), according to general urban planning street corner width all more than 50m.Required main material: cable termination steel pipe pole 2 bases (double back), approximately 3.2 tons, every base, 300mm copper conductor cable 200m(is by the wide 60m in street corner), non-excavating construction 60m * 4 pipe (reserved by two), 2 of cable inspection wells.Approximately more than 25 ten thousand yuan of every place costs, connection charge is very high.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of arrangement of conductor selector bar, and it has simple in structure, connection and facilitates the characteristics such as attractive in appearance, that cost of manufacture is low.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Comprise the upper cross-arm that is positioned at line masthead section and perpendicular connection, upper cross-arm is left-right symmetric centered by the line bar, its two ends, left and right respectively are provided with three for connecting the insulator of wire, below upper cross-arm, be provided with and line bar lower cross-arm connected vertically, lower cross-arm is positioned at line bar right-hand member, is provided with three above it for connecting the insulator of wire.
The utility model further improves and is:
Three of upper cross-arm left ends are pin insulator for the insulator that connects wire, and three of its right-hand members are suspension insulator for the insulator that connects wire.
Three of lower cross-arms are pin insulator for the insulator that connects wire.
Upper cross-arm parallels with lower cross-arm.
The beneficial effect that adopts technique scheme to produce is: original circuit (arrangement of conductor is upper triangle, lower level) can be connected by this selector bar with newly-built circuit (arrangement of conductor left and right isosceles triangle).The wire that isosceles triangle on former wired bar is arranged is connected with cross-arm left end insulator on this selector bar; Wire horizontal under former wired bar is connected with cross arm insulator under this selector bar right-hand member, move afterwards with cross-arm right-hand member insulator on this selector bar and be connected, the double back wire connects and is connected with newly-built line bar more afterwards with this selector bar, can complete original circuit and be connected with the transition of newly-built line conductor.It has simple in structure, cost of manufacture is low, connection facilitates the characteristics such as attractive in appearance.The mode that adopts before the cable termination steel pipe pole to realize that transition connects is compared, but more than 250,000 yuan of each transition connection direct saving fee of materials.Carry out double back wire transition connection if promote the use of this selector bar, save the operating expenses considerable number.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view that Fig. 1 is used state.
In the accompanying drawings: 1, line bar; 2, upper cross-arm; 3, lower cross-arm; 4, pin insulator; 5, suspension insulator.
Embodiment
From the embodiment shown in Fig. 1-2, comprise the upper cross-arm 2 that is positioned at line bar 1 top and perpendicular connection, upper cross-arm 2 left-right symmetric centered by line bar 1, its two ends, left and right respectively are provided with three for connecting the insulator of wire, below upper cross-arm 2, be provided with and line bar 1 lower cross-arm 3 connected vertically, lower cross-arm 3 is positioned at line bar 1 right-hand member, is provided with three above it for connecting the insulator of wire.
Three of upper cross-arm 2 left ends are pin insulator 4 for the insulator that connects wire, and three of its right-hand members are suspension insulator 5 for the insulator that connects wire.
3 three of lower cross-arms are pin insulator 4 for the insulator that connects wire.
Upper cross-arm 2 parallels with lower cross-arm 3.
Using method:
The wire that isosceles triangle on former wired bar is arranged is connected with cross-arm left end insulator on this selector bar; Wire horizontal under former wired bar is connected with cross arm insulator under this selector bar right-hand member, move afterwards with cross-arm right-hand member insulator on this selector bar and be connected, the double back wire connects and is connected with newly-built line bar more afterwards with this selector bar, can complete original circuit and be connected with the transition of newly-built line conductor.
It has simple in structure, cost of manufacture is low, connection facilitates the characteristics such as attractive in appearance.
