Description
Technical field
The utility model relates to electrical facility technical field, is specifically related to a kind of suspended compound insulator hardware end composite seal structure.
Background technology
Composite insulator is as line insulator of new generation with the performance of its excellence, and the use amount in China's electrical network grows with each passing day, and brings very large benefit to the safe operation of electric power system.Although end part of composite insulator sealing problem, adopt combined high-temperature glue sealing structure, substantially solved, because manufacture craft is complicated, need to carry out two pressures, be unfavorable for the lower and streamlined effect of composite insulator production cost.Therefore, the hermetically-sealed construction of further improvement suspended compound insulator hardware end, improve sealing property, composite insulator is reduced costs, realize streamlined operation, improve composite insulator sealing property, ensure that insulator long-term safety is run all tools and had very important significance.
Summary of the invention
The utility model has made improvement on the basis of existing insulator sealing structure, its object is to the reduction production cost of suspended compound insulator, is convenient to streamlined operation and improves sealing property, ensures the safe operation of insulator.
The above-mentioned purpose of the utility model insulator is achieved through the following technical solutions.
A kind of suspended compound insulator hardware end composite seal structure, comprises with the plug of sheath, sulphurated siliastic fluid sealant, concave shape sealing ring, concave-convex seal interface and gold utensil.
A kind of suspended compound insulator hardware end composite seal structure, its mandrel outer is coated with sheath, and the end of insulator hardware is the space that an internal diameter expands, and plug is plugged in insulator hardware,
A concave shape sealing ring is placed with in insulator hardware end; Insulator hardware end inner ring is concave-convex seal interface, and the side of concave shape sealing ring is closely sealed on the inner ring of insulator hardware end; Sulphurated siliastic fluid sealant is filled with outside insulator hardware end and between the sheath of plug; Like this, described composite seal structure is by concave shape sealing ring, concave-convex interfacial seal interface and sulphurated siliastic fluid sealant triple seal Structure composing.
Sheath on described plug withstands on concave shape sealing ring.
The material of described concave shape sealing ring adopts the silicon rubber of high temperature resistant sulfuration to make.
The advantage of this structure is:
The connection of composite insulator hardware end and plug adopts press-contacting connection structure, and the connection of hardware end and core bar jacket is permanent seal.Seal combination inside and outside this silicon rubber, physics and chemistry sealing mechanism simultaneously and the composite seal structure of depositing, can stop entering of aqueous vapor and impurity long-term effectively, ensure the safe operation of suspended compound insulator.
The utility model suspended compound insulator hardware end composite seal structure, the features such as its fluid sealant has obvious high-low temperature resistant, solar irradiation, ozone and anti-soil and to wet aging of electrical corrosion performance, and sealing life is long.The utility model product structure is reasonable, and feasible process is economical and practical, has both reduced production cost, has been convenient to streamlined operation, and which in turn improved the sealing property of product.

Embodiment
The utility model hermetically-sealed construction specific embodiments is introduced in detail below in conjunction with accompanying drawing:
As shown in the embodiment of Fig. 1 and Fig. 2, a kind of suspended compound insulator hardware end composite seal structure, its insulator hardware 6 and plug 1 same as the prior art, plug 1 is coated with sheath 2.The end of insulator hardware 6 is the space that an internal diameter expands, and plug 1 is plugged in insulator hardware 6.Be placed with a concave shape sealing ring 4 in insulator hardware 6 end, the material of concave shape sealing ring 4 adopts the silicon rubber of high temperature resistant sulfuration to make.Sheath 2 on plug 1 withstands on concave shape sealing ring 4.The concave shape sealing ring 4 of composite seal structure, be utilize the strain of concave shape sealing ring 4 and sheath 2, the close contact of insulator hardware 6 realizes.After insulator hardware 6 crimps, concave shape sealing ring 4 produces certain strain, the internal structure power that strain occurs, impels close contact surface spacing to reduce, substantially increases the sealing property at interface.Insulator hardware 6 end inner ring is processed as concave-convex seal interface 5, and the side of concave shape sealing ring 4 is closely sealed on the inner ring of insulator hardware 6 end due to the effect of concave-convex seal interface 5.Thoroughly seal for making insulator hardware 6, plug 1 and the external world; sulphurated siliastic fluid sealant 3 is filled with outside insulator hardware 6 end and between the sheath 2 of plug 1; sulphurated siliastic sealing can protect internal layer hermetically-sealed construction effectively; directly shine from sunlight; ozone, dirty wet creepage erosion and external force clashing and breaking, make it maintain comparatively high sealing performance.Like this, the concave shape sealing ring 4 placed by insulator hardware 6 inside, concave-convex interfacial seal interface 5 and the triple seal structure of the outside sulphurated siliastic fluid sealant 3 of insulator hardware 6, make equipment seal completely.
Insulator hardware 6 end adopts press-contacting connection structure with the connection with the plug 1 of sheath.Before crimping, concave shape sealing ring 4 is enclosed within plug 1 termination of coated good sheath 2, concave shape sealing ring 4 and plug 1 termination and sheath 2, insulator hardware 6 are in interference fit.After having crimped, withhold at ad-hoc location again, make concave shape sealing ring 4 produce suitable strain, the elasticity by sheath 2 makes to form multiple miniature concave-convex sealing surface between itself and insulator hardware 6.Finally carry out outside sulphurated siliastic fluid sealant 3 to seal.
This novel sealing structure is except utilizing room temperature vulcanized silicone rubber sealing and elasticity concave shape sealing ring and gold utensil to overlap close contact and sealing, because of the interference fit of concave shape sealing ring and gold utensil, sheath, form multiple miniature concave-convex seal interface, make sealing more reliable.
