Technical field
The utility model belongs to the transmission line of electricity design field, is specifically related to the OPGW optical cable insulation drop wire clip in a kind of 500kV of can be applicable to circuit.
Background technology
At present; China's high pressure, most of OPGW optical cable (the OPGW optical cable that adopts of extra high voltage network; Optical Fiber Composite Overhead Ground Wire, full name " Optical Fiber composite overhead Ground Wire ") and the method that is used of common ground wire transmission line of electricity is protected.Common ground wire adopts the method for operation of graded insulation single-point grounding usually, and OPGW is owing to its communication function, so adopt the method for operation of pursuing tower ground connection all the time.
Under the normal operation, can generate an electromagnetic field around the transmission line wire, and then on ground wire, produce electromagnetic induction voltage and electrostatic induction voltage.Common ground wire is because adopt the mode of graded insulation, avoided between itself and the OPGW optical cable and and the earth between form the loop, and then can not produce induction current, so the energy loss on the common ground wire is very little.The OPGW optical cable forms the loop like this because its singularity adopts the mode by tower ground connection always between OPGW optical cable and the earth, have energy loss in the OPGW optical cable midium or long term, and in cycle transmission line of electricity life-cycle, this loss is very big.
The utility model content
The utility model is a kind of novel 500kV circuit OPGW optical cable insulation drop wire clip, make OPGW optical cable downlead and body of the tower insulate, cooperate OPGW common uses the such as surplus cable frame and OPGW optical cable insulation splice tray of insulating, and then realized the method for operation of OPGW graded insulation, reduce the electric energy loss that causes on the OPGW optical cable significantly, play the effect of ground wire lightning protection simultaneously.
For achieving the above object, the utility model is by the following technical solutions:
A kind of 500kV circuit OPGW optical cable insulation drop wire clip, this insulation drop wire clip is fixed on the body of the tower master material of iron tower, its improvements are: this insulation drop wire clip comprises insulator, OPGW optical cable, wiring and iron tower fixed mount, one end of described iron tower fixed mount is connected with body of the tower master material, its other end is connected with insulator, and described OPGW optical cable is fixed on the insulator by wiring.
Wherein, the creepage ratio distance 〉=170mm of described insulator, the structure height 〉=200mm of described insulator.
Wherein, described iron tower fixed mount is selected S sections tower fixed mount for use.
Wherein, described iron tower fixed mount is connected by bolt respectively with insulator with body of the tower master material.
Because the beneficial effect that has adopted technique scheme, the utility model to obtain is:
The utility model optical cable insulation drop wire clip provides the reliable technique support for the OPGW graded insulation single-point grounding method of operation, it makes OPGW optical cable downlead and body of the tower insulation, thereby realize the method for operation of graded insulation single-point grounding, greatly reduced the induction current loss, for electric system brings huge economic benefit, and then has positive effect to building " energy-saving, environment-friendly type " transmission line of electricity.
Description of drawings
Fig. 1 is the structural representation of 500kV circuit OPGW optical cable insulation drop wire clip;
Wherein, 1-insulator, 2-OPGW optical cable, 3-wiring, 4-iron tower fixed mount, 5-body of the tower master material.
Embodiment
Below in conjunction with accompanying drawing the described insulation drop wire clip of utility model is described in further detail.
As shown in Figure 1, this routine described OPGW optical cable insulation drop wire clip comprises insulator 1, OPGW optical cable 2, wiring 3 and iron tower fixed mount 4, and this insulation drop wire clip is installed on the body of the tower master material 5 of iron tower by iron tower fixed mount 4.Iron tower fixed mount 4 is selected S sections tower fixed mount for use, one end of this S sections tower fixed mount is connected with body of the tower master material 5 by bolt, the end of body of the tower master material 5 holds out against the middle bending part at S sections tower fixed mount, and the other end of S sections tower fixed mount 4 is connected by the lower end of bolt with insulator 1.The effect that insulator 1 plays insulation and supports can be insulated the downlead and the body of the tower master material 5 of OPGW optical cable 2 by insulator 1, thereby is convenient to realize the method for operation of OPGW cable segment insulation single-point grounding.Insulator 1 can be selected porcelain or composite insulator for use, and insulator is creepage than distance 〉=170mm, structure height 〉=200mm.OPGW optical cable 2 is fixed on the upper end of insulator 1 by wiring 3, owing to be surrounded by optical fiber in the OPGW optical cable 2, so the OPGW optical cable should not use the nonflexible line clamping fixed, so the utility model adopts wiring 3 that OPGW optical cable 2 is fixed on the insulator 1, be that optical cable has obtained fixing like this, avoided optical cable to sustain damage again simultaneously.
This 500kV circuit OPGW optical cable insulation drop wire clip makes optical cable and body of the tower insulation, has realized that the insulation of optical cable is drawn down, can cooperate common use such as surplus cable frame and splice tray in actual applications, further realizes the method for operation of OPGW graded insulation single-point grounding.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of this claim scope.
