Technical field
The utility model relates to a kind of insulator, and especially a kind of 550KV solid core post insulator belongs to electric power transfer unit technical field.
Background technology
Insulator is commonly called as porcelain vase, is the insulator that is used for supporting lead.It can guarantee that lead and cross-arm, shaft tower have enough insulation, thereby is widely used in the overhead type transmission system.Because it is in operation and not only needs to bear the loading of lead vertical direction and the pulling force of horizontal direction, and need stand Exposure to Sunlight, drench with rain, the corrosion of climate change and chemical substance, therefore, insulator should have good electric property, and enough mechanical strengths and resistant to rust ability are arranged again.
Existing insulator adopts more piece porcelain insulating spare usually and goes up the fastening structure of lower flange, though can meet the demands substantially, but often has following defective: 1, consideration based on economy and mechanical strength, flange adopts usually and makes such as the cheap metal of prices such as iron, and its resistant to rust ability is relatively poor; 2, the structure that more piece porcelain insulating spare connects in turn, interface each other increases, and it is difficult more that sealing becomes, and causes the sealing property of insulator integral body relatively poor, influenced electric property; 3, because multi-section structure causes the insulator parts more, structure becomes complicated on the one hand, also can cause the increase of failure rate, maintenance workload on the other hand.
Therefore, can make it when possessing original support wire, insulating effect, overcome above-mentioned defective, for those skilled in the art have opened up brand-new thinking by to composition, the material of insulator and even the transformation of assembling.
The utility model content
In order to solve the problems of the technologies described above, the utility model aims to provide a kind of big load 550KV solid core post insulator, it can be under the prerequisite of keeping the insulator existing capability, by architecture advances, overcome that the load that exists in the prior art is little, resistant to rust and stain resistance is poor, electric property is bad, complex structure drawback such as easy care not.Its technical scheme that adopts is as follows:
Should mainly comprise by big load 550KV solid core post insulator: upper flange, three solid core post insulators porcelain spare, adpting flange and the lower flange that connect in turn, described three solid core post insulators are connected to form porcelain spare group in turn with porcelain spare by adpting flange, described upper flange is connected to an end of described porcelain spare group, the other end of described porcelain spare group is connected with described lower flange, and has the PRTV coating of resistance to soiling with the spraying of porcelain spare outer surface at three solid core post insulators.
Preferably, described upper flange, adpting flange and lower flange adopt spheroidal graphite cast-iron QT450-10.
Preferably, the outer surface at described upper flange, adpting flange and lower flange plates the strong zinc layer of resistant to rust ability.
Preferably, described solid core post insulator adopts C130 with porcelain spare.
Preferably, described adpting flange is provided with screw, realizes being connected and fixed by the screw rod and the nut that match with it.
Compared with prior art, the utlity model has following advantage:
1, load is bigger;
2, resistant to rust ability and stain resistance strengthen greatly;
2, sealing property and electric property improve;
3, simple in structure, easy to maintenance;
4, prolong useful life.

Description of drawings
Fig. 2: the dimensional drawing of big load 550KV solid core post insulator of the present utility model.
Among the figure: 1, upper flange; 2, solid core post insulator porcelain spare; 3, adpting flange; 4, nut; 5, lower flange.
The utility model is described in further detail below in conjunction with accompanying drawing and example:
Embodiment
An embodiment of the present utility model the figure shows the structural representation of a big load 550KV solid core post insulator as shown in Figure 1, below will explain detailedly.
This insulator is applicable to industrial frequency AC nominal voltage of a system 500kV power transformation, power distribution equipment and electric plant as the insulation and the support of current-carrying part, can adapt to-40 ℃～+ 40 ℃ ambient temperature, satisfies each regional transmission system of China's length and breadth of land.It mainly comprises: upper flange 1, three solid core post insulators porcelain spare 2, adpting flange 3 and the lower flange 5 that connect in turn, three solid core post insulators are connected to form porcelain spare group with porcelain spare 2 in turn by adpting flange 3, upper flange 1 is connected to an end of porcelain spare group, the other end of porcelain spare group is connected with lower flange 5, and has the PRTV coating of resistance to soiling with the spraying of porcelain spare outer surface at three solid core post insulators.
Screw also is set on the adpting flange 3, and solid core post insulators are with being connected and fixed between the porcelain spare 2 before and after realizing by the screw that matches with it and nut 4.
A little less than considering that metal resistant to rust abilities such as QT450-10, can plate the strong metal level of resistant to rust ability at the outer surface of upper flange 1, adpting flange 3 and lower flange 5, for example hot galvanizing, the zinc layer should be continuous, even, smooth, and securely attached on the flange outer surface, and should carry out zinc layer bonding strength test; Zinc coating thickness should meet the regulation of JB/T 8177-1999.
Three solid core post insulators can adopt C130 with porcelain spare 2.
For the whole sealing of reinforced insulation, improve its electric property, in the junction of each parts sealant and adhesive (not shown) can also be set, sealant for example adopts silicon rubber, and adhesive for example adopts the 525# portland cement as cement glue.
The size of this insulator each several part for example is:
| H | 4100mm | d1 | 300mm |
