Abstract
A 10kV power distribution circuit insulation tower head is disclosed, which is characterized by adopting hydrophobic high-strength insulation bar to be assembled with needle-typed insulator by a gold tool and form an insulation tower head integer, or adopting hydrophobic high-strength insulation bar to be assembled with gold tool directly and form an insulation tower head. By using the invention, the insulation level of the power distribution circuit can be greatly improved, the thunder discharge air gap can be obviously enlarged, the lightning stroke and line break accidents can be effectively prevented and the climbing distance can be expanded, further, the structure type is easy in improving self-cleaning ability and the occurrence of pollution flashover can be basically and completely precluded, which is beneficial in charged operation, simple in an operation process and improves the operation security.
Description
Technical field
The invention belongs to the ultra-high-tension power transmission line field, relate to a kind of 10kV distribution line insulation tower head (supporter of aerial condutor).
Background technology
Compare with the insulation level of 110kV and above transmission line, 10kV distribution line insulator creep distance is less, the air clearance L between electrified body (lead) and the earth electrode (iron cross arm)
1(creep distance) is less, is generally 20cm, in case direct lightning strike takes place, flashover takes place very easily then.In addition, it is relatively poor that regional atmospheric environment of living in is netted in the part city, and contamination is serious on the insulator.During big or dense fog weather, be easy to take place pollution flashover in humidity.In addition, during foreign material short circuit pin insulators such as branch, ribbon, kite, food bag, also be easy to cause relative ground circuit, perfect developing into alternate flashover again after the phase current potential raises.
" insulator crossarm " of contrast application number 98229706.8, its purpose of design also is the mechanical strength that guarantees shaft tower when improving the shaft tower insulation level, but its long-time back stamen rod that uses is different with the coefficient that the insulation full skirt expands with heat and contract with cold, the two can not keep fitted seal the slit to occur, the contamination situation will appear in stamen rod and the insulation full skirt, the insulation level of this insulator crossarm will reduce greatly when weather is moistening, when serious even relative ground circuit can occur.And the present invention is an integral body, and dust etc. is filthy to be assembled even have, but filth can be blown away or washes away when the weather of wind or rain is arranged, thereby has kept higher insulation level.
Summary of the invention
The present invention is that purpose provides a kind of 10kV distribution line insulation tower head, solve the problems such as lightning stroke flashover, pollution flashover, phase ground short circuit and alternate flashover that existing 10kV distribution line is prone to, can significantly improve the insulation level of distribution line, substantially can stop the generation of pollution flashover accident fully, and help carrying out live line working.
Technical scheme of the present invention is: a kind of 10kV distribution line insulation tower head is characterized in that: adopt hydrophobic type high strength insulating rod, assemble with connecting gold utensil and pin insulator, form an insulation tower head integral body; Or adopt hydrophobic type high strength insulating rod directly to assemble with being connected gold utensil, form an insulation tower head integral body.Thereby increased greatly tower head relatively with the phase insulation spacing, increase substantially the insulation level of distribution line.
Aforesaid 10kV distribution line insulation tower head, it is characterized in that: by pin insulator 1,2,3, connect gold utensil 4,5,6,7,8,9,10 and hydrophobic type high strength insulating rod 11,12 compositions, connecting gold utensil 4,5,6 is contained in respectively on the pin insulator 1,2,3, respectively there is the groove of 1 insertion wire the upper end, connecting gold utensil 7,8 is fixed on pin insulator 1,3 on insulating rod 11 two ends respectively, connect gold utensil 9,10 and be used for insulating rod 11 is fixedly mounted on insulating rod 12, insulating rod 11 and insulating rod 12 across.
Aforesaid 10kV distribution line insulation tower head, it is characterized in that: form by connecting gold utensil 4,5,6,9,10 and hydrophobic type high strength insulating rod 11,12, connecting gold utensil 4,5,6 upper ends respectively has the groove of 1 insertion wire, connecting gold utensil 4,6 is fixed on insulating rod 11 two ends, connecting gold utensil 5 is fixed on insulating rod 12 terminations, connect gold utensil 9,10 and be used for insulating rod 11 is fixedly mounted on insulating rod 12, insulating rod 11 and insulating rod 12 across.
Useful effect
1. the present invention has strengthened the spacing L that relatively insulate
1With phase insulation spacing (about 2L
1), (spacing L promptly relatively insulate to make the air clearance of thunder discharge
1) (as shown in Figure 1) enlarge markedly, and is increased to about 90cm～110cm from original to 20cm is minimum, (lead is to body of the tower, L for discharge path
1+ L
2) having increased 3～4 times, insulation level is increased to 110kV circuit level, makes insulation level be higher than the overvoltage that is formed by the induction thunder, thereby prevents the lightning-caused breaking accident of lightning stroke trip and insulated conductor.
2. the present invention enlarges markedly creep distance, makes the creepage distance under the filthy state enlarge markedly the minimum 90cm of being increased to of 20cm, and its structural shape is easy to improve the automatically cleaning ability, can prevent the generation of pollution flashover accident substantially fully.In addition, when on cross-arm and electric pole, articulating foreign material or twig, can not influence its normal operation substantially yet.
3. help live line working.At present; the live line working of urban distribution network is carried out comparatively general; at the charged for replacement insulator, change cross-arm, when moving bar; need insulate to iron cross arm or body of the tower and cover and adopt insulator crossarm to carry out electrified body and shift; make the operation sequence relative complex; and adopt insulation tower head not only to help simplifying operation procedure, and improved operational security.
The present invention is in light weight, mechanical strength is high, has extremely strong hydrophobicity, adapts to long-term outdoor climatic environment, and has high insulation level, satisfies the requirement of distribution line insulation level fully.
