A kind of layer-by-layer isolated insulation compound cable support of drawer type
Technical field
The present invention relates to field of electrical equipment more particularly to a kind of layer-by-layer isolated insulation compound cable supports of drawer type.
Background technique
Existing cable bracket material is generally metal or composite, and structure is by vertical column and lateral trailing arm group
At.According to number of cables how much, column assembles 3-6 layer trailing arm, is highly 150-200mm, centre between trailing arm and trailing arm
Without any quarantine measures, distance is generally 800mm between two groups of columns.Fire prevention isolation only Lan Gou intersection or cell with
Cell is isolated using piecewise formula.
The shortcomings that this cable bearer and risk are clearly:1, cable is more in disorder, influences substation's entirety vision effect
Fruit;2, without fire prevention quarantine measures between power cable and control cable, optical cable;3, piecewise formula fire prevention isolation, no matter any one
Fire occurs for the cable of which layer of section, and fire behavior can all feed through to the cable of adjacent layer, so as to cause unrelated cable floor in the section
Cable is all damaged, and causes all electric power of whole station and signal interruption, while can also feed through to other association power stations.
Summary of the invention
In view of the above drawbacks of the prior art, the present invention provides a kind of layer-by-layer isolated insulation composite cable branch of drawer type
Frame, including vertical columns, several trailing arms and several fire prevention drawer type isolation boards are arranged at intervals with trailing arm installation on the column
Hole, the trailing arm are fixedly mounted on the column by the trailing arm mounting hole, and the trailing arm, which is equipped with, is used for the drawer type
The drawer guideway of isolation board installation.
Preferably, the trailing arm is equipped with the bundle cable hole for tying up cable.
Preferably, the location hole for limiting and fixing the drawer type isolation board is additionally provided on the inside of the trailing arm.
Preferably, the drawer type isolation board is L-type isolation board.
Preferably, grounding copper bar mounting hole is additionally provided on the column.
Preferably, the trailing arm two sides are equipped with the drawer guideway for drawer type isolation board installation.
The invention has the advantages that:
The layer-by-layer isolated insulation compound cable support of drawer type provided by the invention, using the totally-enclosed fire prevention of layer-by-layer formula, fire
Incidence minimizes, even if fire occurs, any one layer of generation fire will not all spread to other layer line cables, by fire damage
It minimizes.Modular support is set up, and disassembly freely, facilitates cable to lay, and reduces difficulty of construction, improves working efficiency and work
Cheng Zhiliang.Drawer type is set fire diaphragm structure simultaneously, conveniently opening and closing, is convenient for enlarging, increase-volume, maintenance, operation and maintenance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of a preferred embodiment of the invention;
Fig. 2 is the application schematic diagram of a preferred embodiment of the invention.
Specific embodiment
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
As shown in Figure 1, a kind of layer-by-layer isolated insulation compound cable support of drawer type, including vertical columns 1, several trailing arms 2
With several fire prevention drawer type isolation boards 3, using composite material, intensity height, good toughness, thermosetting property are good, will not generate metallic support
Because of deformation caused by overload or temperature change.It is arranged at intervals with multiple trailing arm mounting holes, grounding copper bar mounting hole 6 on column 1, holds in the palm
Arm 2 is fixedly mounted on column 1 by trailing arm mounting hole, and combined installs the trailing arm 2 of different spacing, trailing arm 2 according to demand
Material can be identical as column 1, corner rounding off, prevents from accidentally injuring construction personnel.Grounding copper bar mounting hole 6 is for installing grounding copper
Row.
2 one or both sides of trailing arm are equipped with the drawer guideway 4 installed for drawer type isolation board 3, and guide rail 4 can be slot type structure
Guide rail etc., guide rail 4 form a complete guide rail group convenient for the installation of drawer type isolation board 3, the trailing arm 2 of two same levels, every
Realize that installation is fixed by this group of trailing arm 2 from plate 3.It is additionally provided on the outside of trailing arm 2 for limiting and fixing determining for drawer type isolation board 3
Position hole completes locking, prevents from falling off after drawer type isolation board 3 is pushed into commitment positions, and when opening only needs isolation of acting rashly upwards
Plate 3 completes unlock, can extract isolation board 3 out, convenient and efficient.
Trailing arm 2 is equipped with the bundle cable hole 5 for tying up cable.
Drawer type isolation board 3 is L-type isolation board, is made of fireproof composite, fire protecting performance is splendid, can be in layer and layer
Effective fire prevention isolation is formed between cable, convenient for opening, being closed, while by cable closure, cable ditch is clean and tidy, beautiful and generous.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
