The utility model discloses the special-purpose cross-arm of a kind of composite type, it comprises the reinforced glass fibre plastic cross-arm main body being connected and composed by split cross-arm, in the described reinforced glass fibre plastic cross-arm main body of its main points, be provided with two ends and connect silk braid pipe in exposing, leading screw is inserted respectively at the two ends that connect silk braid pipe in described, the outer end of described leading screw is connected with the fixedly anchor ear with fixing hole by flange, and described leading screw is provided with regulating handle.When the utility model conducting transmission line promotes lead wire and earth wire transformation; by Combined cross arm, shaft tower is reinforced temporarily; can reach firm shaft tower; remove former cross-arm or after cutting former cross-arm; the object of direct lifting lead wire; the utility model is simple to operate, on-the-spot easy to use, flexible, has reduced workload and artificial.Through scene application, from safety, technology, operating aspect, all meet the requirement of electric power operation rules, in the work of having solved, there is the dangerous and loaded down with trivial details technical problem of operation.
Description
technical fieldthe utility model belongs to power line construction technical field of tools, is specifically related to the special-purpose cross-arm of a kind of composite type.
background technologymore outstanding in transmission line passage contradiction, line is got down the highway, expressway, railway and local development zone, the very fast construction in market, caused the ground of ultra-high-tension power transmission line to below, road surface and other cross over thing safe distances deficiency, caused transmission line safe operation hidden danger, therefore cause " increase shaft tower and promote lead wire and earth wire " transformation project increasing year by year, when promoting lead wire and earth wire, wire can directly rise on the both sides phase cross-arm of new tower, but middle phase conductor hinders because there is cross-arm top, only having break line to break end to extract out after H-frame pole could reclosing, promote, cause reclosing 1 time that at least needs to break of middle phase conductor, increase at least 1 joint, reduced the reliability of wire safe operation after transformation.
summary of the inventionthe purpose of this utility model is by Combined cross arm, shaft tower to be reinforced temporarily, can reach firm shaft tower, removes former cross-arm or after cutting former cross-arm, directly the object of lifting lead wire, provides a kind of composite type special-purpose cross-arm, to overcome the deficiencies in the prior art.
To achieve these goals, the special-purpose cross-arm of the utility model composite type, it comprises the reinforced glass fibre plastic cross-arm main body being connected and composed by split cross-arm, in the described reinforced glass fibre plastic cross-arm main body of its main points, be provided with two ends and connect silk braid pipe in exposing, leading screw is inserted respectively at the two ends that connect silk braid pipe in described, the outer end of described leading screw is connected with the fixedly anchor ear with fixing hole by flange, and described leading screw is provided with regulating handle.
For improve reinforced glass fibre plastic cross-arm main body with in connect the fastness that is connected of silk braid pipe, the described reinforced glass fibre plastic cross-arm main body mouth of pipe with in connect silk braid pipe corresponding site be provided with flange.
The two ends that fixedly anchor ear is arranged on cross-arm are mainly used in and being connected of the body of rod, and leading screw is mainly used for regulating because shaft tower is with opening the range error causing.
When the utility model conducting transmission line promotes lead wire and earth wire transformation; by Combined cross arm, shaft tower is reinforced temporarily; can reach firm shaft tower; remove former cross-arm or after cutting former cross-arm; the object of direct lifting lead wire; the utility model is simple to operate, on-the-spot easy to use, flexible, has reduced workload and artificial.Through scene application, from safety, technology, operating aspect, all meet the requirement of electric power operation rules, in the work of having solved, there is the dangerous and loaded down with trivial details technical problem of operation.
accompanying drawing explanationaccompanying drawing is the structural representation of the local one end of the utility model.
In figure 1, reinforced glass fibre plastic cross-arm main body 2, in connect silk braid pipe 3, leading screw 4, flange 5, fixedly anchor ear 6, regulating handle 7, flange
embodimentwith reference to accompanying drawing, it comprises the reinforced glass fibre plastic cross-arm main body 1 being connected and composed by split cross-arm the utility model, in being provided with in described reinforced glass fibre plastic cross-arm main body 1 that two ends expose, connect silk braid pipe 2, leading screw 3 is inserted respectively at the two ends that connect silk braid pipe 2 in described, the outer end of described leading screw 3 is connected with the fixedly anchor ear 5 with fixing hole by flange 4, and described leading screw 3 is provided with regulating handle 6.
For improve reinforced glass fibre plastic cross-arm main body 1 with in connect the fastness that is connected of silk braid pipe 2, described reinforced glass fibre plastic cross-arm main body 1 mouth of pipe with in connect silk braid pipe 2 corresponding site be provided with flange 7.
The utility model it be according to the different roots of overhead line structures open, the normal data in different bars footpath in conjunction with work on the spot demand, the reinforced glass fibre plastic cross-arm main body that the applicable least root of processing is opened, the fixedly anchor ear of reinforced glass fibre plastic cross-arm main body two ends design can directly be fixed on respectively on two corresponding overhead line structures, convenient fixing, time saving and energy saving.
Benefit of the present utility model:
1, economic benefit;
Single operation is saved time 57 minutes, can reduce interruption duration 57 minutes, and the circuit average load 1699.75kVA while transforming according to having a power failure calculates, and can increase power transmission amount 161500 degree.
Reduce operating personnel 7 people, according to the minimum wage of employing, calculate, 80 yuan per capita, save 7 people and can save 560 yuan of labour costs.
Reduce on average at least 1 cover at every turn of lead splicing sleeve, 200 yuan.
Civil compensation expense reduces 5100 yuan.
This movable common property life is moved and is taken 370 yuan.
According to above benefit calculation, 560+200+5100-370=5490 unit, only at 220kV, covering positive II line can cost saving 5490 yuan in once transforming, and increases power transmission amount 161500 degree.
Since 2011 come into operation, in 27 transmission lines transformations, use altogether in 3 years, obtained larger economic benefit; Amount to 148230 yuan
2, safety benefit;
Because wire no longer disconnects reclosing, reduced terminal, improved the reliability that wire is in operation, reduced the workload that terminal detects, reduced operating cost.
3, social benefit;
The direct lifting of wire, below low pressure is handed over across no longer needing to coordinate to have a power failure, improved client's electricity consumption satisfaction rate, also increased accordingly company's electricity sales amount, under line, young crops infringement significantly reduces, greatly reduce civil disputation, obtained and in guard plot along the line, related to villager's understanding of young crops infringement and support, improved corporate image.
Conclusion: " the special-purpose cross-arm of composite type ", the on-the-spot proof of using, its intensity not only can reach the intensity of former cross-arm, and reached the target that broken string reclosing number of times eases down to at least 1 time for 0 time, reduce greatly the activity duration, paid for blue or green expense and on-the-spot recruitment, reduced the consumption of material, obtained will be good than re-set target many effects.
