Description
Technical field
The present invention relates to electrical network field, particularly a kind of line insulator.
Background technology
In mesohigh or low-voltage circuit erection engineering, each root straight line pole all need make between wire and wire with line insulator or wire and electric pole, to insulate between cross-arm, preventing the effect that wire leaks electricity.
In prior art, long pillar insulator or the pin insulator adopting ceramic material, when pillar insulator or pin insulator are installed, needs to use binding colligation.Pillar insulator or pin insulator easy fracture under harsh weather (thunder and lightning, severe cold, storm) condition damages, and binding easily loosens, and causes wire to depart from from insulator, causes the accident such as phase fault and single-phase earthing or fault.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of structure simple, be convenient to install, install firmly, the line insulator of good insulation preformance.
Technical scheme of the present invention is:
A kind of line insulator, comprising:
Insulating case 2, which is provided with cable clamping interface 4;
Maxilla steel disc 3, is close to the upper surface of described insulating case 2, which is provided with bolt hole;
Lower jaw steel disc 5, is close to the lower surface of described insulating case 2, which is provided with bolt hole;
Bolt 1, is each passed through lower jaw steel disc 5 and maxilla steel disc 3;
Nut, is connected with described bolt 1 threaded engagement.
Preferably, the described central shaft of cable clamping interface 4 and the central axis of bolt hole.Certainly, bolt hole also tiltable is arranged, but this kind of set-up mode, steadiness is installed high.
Preferably, lower jaw steel disc 5 setting corresponding with the bolt hole on maxilla steel disc 3 and equal diameters.
Preferably, multiple bolt 1 is set.In order to maxilla steel disc and lower jaw steel disc can more firmly fixed insulation covers, multiple bolt can be set.Certainly, now lower jaw steel disc 5 and maxilla steel disc 3 to arrange multiple bolt hole accordingly.
Beneficial effect of the present invention is:
Line insulator of the present invention, structure is simple, be convenient to make, cost is low, be convenient to install, install firmly, good insulation preformance.And transport is convenient in the present invention, damage of product rate is almost nil.
Use the present invention can improve the reliability of line security electricity consumption, greatly reduce the failure rate that circuit runs; The present invention compares with pillar insulator with pin insulator, and its advantage in construction is: the present invention without colligation, just can firmly install in line construction, greatly reduces the labour intensity of workmen, improves efficiency of construction.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of line insulator of the present invention;
Fig. 2 is the A-A cross-sectional view of line insulator of the present invention.
Embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, line insulator of the present invention comprises insulating case 2.Insulating case 2 is provided with cable clamping interface 4, cable clamping interface 4 for placing electric wire, the coating electric wire that insulating case 2 will be stuck in cable clamping interface 4.Insulating case 2 is prepared from by the insulating material such as rubber or plastics.As shown in Figure 1, dash area then represents insulating case 2, insulating case 2 also can be arranged protection full skirt (vertical dash area, protect full skirt to be annular in material object, Fig. 1 is sectional view).
The upper surface of insulating case 2 is close to by maxilla steel disc 3, and maxilla steel disc 3 is wider than insulating case 3, and maxilla steel disc 3 and the discontiguous position of insulating case 2 are provided with bolt hole.
The lower surface of insulating case 2 is close to by lower jaw steel disc 5, and lower jaw steel disc 5 is wider than insulating case 3, and lower jaw steel disc 5 and the discontiguous position of insulating case 2 are also provided with bolt hole; Bolt hole on lower jaw steel disc 5 is corresponding with the bolt hole on maxilla steel disc 3 to be arranged.
In order to more firmly install, the diameter of bolt hole on lower jaw steel disc 5 and maxilla steel disc 3 is equal, and the central axis of the central shaft of bolt hole and cable clamping interface 4.
Bolt 1 is each passed through the bolt hole of lower jaw steel disc 5 and maxilla steel disc 3, is finally fixed by nut.
In order to maxilla steel disc and lower jaw steel disc can more firmly fixed insulation covers, multiple bolt can be set.Certainly, now, lower jaw steel disc 5 and maxilla steel disc 3 will arrange multiple bolt hole accordingly.
Use the line insulation period of the day from 11 p.m. to 1 a.m of the present invention, by electrical wire fastener in the cable clamping interface 4 of insulating case 2, then maxilla steel disc 3 and lower jaw steel disc 5 are placed (bolt hole aligning), by bolt 1 successively through lower jaw steel disc 5 and maxilla steel disc 3, be finally fixed by nut.
