Description

Fixing support for three-phase five-wire

Technical Field

The utility model belongs to the technical field of the electric power facility installation, specifically indicate a fixed bolster for three-phase five-wire.

Background

Currently, along with the increasing pace of the development of Chinese electric power, the Chinese power grid is also rapidly developed. The utilization rate of cables is higher and higher in urban power grid construction and infrastructure construction. Three-phase five-wire cables are particularly popular for use. The three-phase five-wire cable is characterized by that it has five mutually-insulated core wires, its exterior is equipped with plastic sheath or steel armour and plastic sheath for covering said five core wires, and the five core wires are respectively correspondent to A, B, C, zero line and PE wire.

The Chinese patent authorization publication number is: CN205646720U, the utility model discloses a single three-phase cable mounting fixture is 2016 month 10 12 days in the grant announcement day, including the locating plate, and set up respectively at the locating plate both ends and with the locating plate cooperate the first locating piece that uses, the second locating piece, and set up respectively on locating plate upper portion and with the locating plate cooperation third locating piece that uses, the fourth locating piece, and the third locating piece is connected respectively at both ends, the supplementary bar locating plate of fourth locating piece, and set up the through wires hole between supplementary bar locating plate and locating plate, this design is whole at the fixed three-phase cable that can be fine, but also only be limited to the monolithic stationary to the cable, the heat dissipation is poor, the problem of inconvenient maintenance still exists.

Disclosure of Invention

The utility model aims at overcoming the above-mentioned shortcoming and the not enough that exist among the prior art, provide a simple structure, can realize fixed alone, the radiating effect is good, be convenient for the maintenance be used for the fixed bolster of three-phase five-wire to the five-wire.

For the purpose of realizing above, the utility model discloses a technical solution is a fixed bolster for five lines of three-phase, which comprises a bracket, be provided with the metallic channel on the support, the metallic channel is the U type, its characterized in that: the wire casing has five, arranges around support edge, and wire casing one side is provided with directional chucking screw in it, and the support links to each other with the inflation screw pole is perpendicular through embedding its interior screw, and in the wall body was squeezed into to the inflation screw pole, be provided with the fastening screw cap on the inflation screw pole and compress tightly the screw cap, and the fastening screw cap is close to support one side, compresses tightly the screw cap and is close to wall body one side.

The support is tree-shaped or round or polygonal.

The clamping screw extends into the wire groove from the outside, and an arc-shaped clamping plate is arranged at one end of the clamping screw, which is positioned in the groove.

The bracket is made of a silica gel insulator.

The utility model has the advantages that:

1. when this design was used, squeeze into the wall body with the inflation screw pole in, utilize to compress tightly the nut and make it and wall body in close contact with and fixed, the fastening nut then fixes the support on the inflation screw pole, go into five wire guide inslots with five lines card respectively, and the one-to-one is fixed for separately laying between the electric wire, the radiating effect is good, and the maintenance of being convenient for.

2. The support is dendriform or circular or polygon shape in this design to adapt to different topography, application range is wide.

3. In the wire casing was stretched into by outer in this design chucking screw, the one end that the chucking screw is located the inslot was provided with the arc cardboard, after the wire was put into the wire casing, the chucking screw of screwing utilized the arc cardboard to fix the electric wire to avoid the electric wire to drop, the design of arc cardboard can not harm the electric wire exocuticle again in the chucking electric wire.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of an assembly structure between the clamping screw and the wire groove of the present invention.

In the figure: a bracket 1, a wire guide groove 2, a clamping screw 3, an internal screw 4, an expansion screw rod 5, a fastening screw cap 6,

a pressing screw cap 7 and an arc clamping plate 8.

Detailed Description

The present invention will be described in further detail with reference to the following description and embodiments in conjunction with the accompanying drawings.

Referring to fig. 1 to 2, a fixed bolster for five lines of three-phase, including support 1, be provided with metallic channel 2 on support 1, metallic channel 2 is the U type, metallic channel 2 has five, arranges around support 1 edge, and metallic channel 2 one side is provided with directional chucking screw 3 in it, and support 1 links to each other with expansion screw rod 5 is perpendicular through embedding its interior screw 4 in, and in expansion screw rod 5 squeezed into the wall body, be provided with fastening screw cap 6 and compression screw cap 7 on the expansion screw rod 5, and fastening screw cap 6 is close to support 1 one side, and compression screw cap 7 is close to wall body one side.
