Description
Technical field
What the present invention relates to is a kind of strain insulator iron tower drainage system of transmission line, especially a kind of strain insulator iron tower drainage system that adopts the transmission line of low noise corona free aluminium-alloy pipe cage rigid jumper.
Background technology
The development of China's electric utility is at present advanced by leaps and bounds, and building extra-high voltage grid has become the inexorable trend that electric power is carried.In the transmission line; The drainage wire jumper of strain insulator corner pole is the important component that is related to the transmission line reliability service; The strain insulator string of ultra high voltage power transmission sequence; Wire jumper is all longer, and lead all adopts the 6-8 splitted construction, and reducing wire jumper sag and windage yaw deviant thereof is the effective ways that dwindle strain tower tower head size, reduce project cost.For this reason, UHV transmission line all adopts rigid jumper at present.
Conventional rigid jumper can adopt aluminum pipe formula wire jumper or squirrel-cage wire jumper, and both all can satisfy practical applications.Non junction in the middle of the drainage lead of squirrel-cage rigid jumper, rigid element adopt steel pipe as support, with the fixing drainage thread of rack-mount conductor spacer.Its support adopts plurality of sections of steel pipes flange connection type, and installation and transportation are more convenient, compares aluminum pipe formula rigid jumper and has reduced the tie point in the middle of the drainage thread, and drainage is more reliable, but lead is difficult to keep straight on support, has hemstitching.The drainage of aluminum pipe formula rigid jumper is made up of two parts: drainage sub-conductor+diameter is thick, the good aluminum pipe of rigidity, has the problem of the electric conductor connection of different structure for this reason; At the changeable wire clamp place of drainage sub-conductor to the aluminum pipe transition, owing to adopt the crimping mode, rough, the corona situation is undesirable, and advantage is the rigid element appearance looks elegant.
Aluminum pipe and squirrel-cage wire jumper respectively have pluses and minuses, on the basis of comprehensive both advantages, design a kind of low noise corona free aluminium-alloy pipe cage wire jumper.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing rigid jumper pattern on technology and economy; And a kind of characteristics that both kept aluminum pipe formula wire jumper good looking appearance are provided; Keep the squirrel-cage wire jumper again and do not had the electric field centrostigma; Be difficult for corona, convenient processing and installation take place, technical characteristic is good, the strain insulator iron tower drainage system of the transmission line of economy and beautiful appearance.
The objective of the invention is to accomplish through following technical scheme; A kind of strain insulator iron tower drainage system of transmission line; This system is made up of the soft sub-conductor of drainage, jumper wire spacing rod, aluminum pipe cage rigid jumper and wire jumper insulator string; Described aluminum pipe cage rigid jumper is suspended on the iron tower cross-arm through the wire jumper insulator string, and the two ends of said aluminum pipe cage rigid jumper link with the strain insulator-string drainage wire clamp at iron tower cross-arm two ends respectively, and adds jumper wire spacing rod and install the weight group on demand additional.
Described aluminum pipe cage rigid jumper is a low noise corona free aluminum pipe cage wire jumper; It mainly is made up of drainage sub-conductor, Aluminum Hollow compo pipe, aluminum pipe conductor spacer, joint and anti-dizziness ball; Described joint and joint dock two aluminium-alloy pipes with the aluminum pipe conductor spacer; And with the conductor spacer support, formation one is the aluminum pipe basket structure of regular polygon section.
Pass corresponding drainage sub-conductor in the described aluminium-alloy pipe, fixedly add anti-dizziness ball at the aluminium-alloy pipe two ends of said drainage sub-conductor turnover.
The single length of described aluminium-alloy pipe is controlled at 6-8 rice, and its internal diameter is bigger than drainage sub-conductor external diameter; Aluminium-alloy pipe length after said two butt joints is at 12-16 rice, through drainage sub-conductor non junction wherein.
The present invention is as a kind of improvement; It is with the cancellation of squirrel-cage rigid jumper bracing frame, uses with the sub-conductor radical to equate that aluminium-alloy pipe replaces, through the conductor spacer fixed support; Forming section is the cage construction of regular polygon; Flexible jumper is passed in aluminium-alloy pipe, be equivalent to utilize the rigidity of aluminium alloy sleeve barrel to substitute the supporting role of steel pipe bracing frame like this, still carry out drainage with flexible conductor.
Compared with prior art, the beneficial effect of the utility model is:
A) need not to carry out the drainage conductor compression jointing, effectively guaranteed the drainage performance, save operating expenses simultaneously;
B) a whole set of rigid jumper does not have electric field centrostigma and crimping point, and external diameter eliminated the possibility of corona fully all greater than lead, effectively reduces strain tower place audible noise;
C) avoided the hemstitching of mouse cage lead, appearance looks elegant is coordinated;
D) in light weight, accessory is few, and processing is simple, easy transportation and installation;
E) economy is suitable with conventional squirrel-cage wire jumper, practices thrift cost about 15% than aluminum pipe formula wire jumper.
