Abstract
The utility model relates to a combined high-temperature adhesive sealing structure for a hardware end of an extra-high-voltage suspension type composite insulator. The combined high-temperature adhesive sealing structure consists of O-shaped sealing rings, a core rod with a jacket, an end hardware accessory and high-temperature vulcanizing silicone rubber, wherein the end hardware accessory is in pressing connection with the core rod with the jacket; two O-shaped sealing rings are arranged in an annular groove of the end hardware accessory and are in interference fit with each other; the core rod with the jacket is inserted, and first seal is formed by secondary pressing; and the end hardware accessory and the core rod with the jacket are sealed by using the high-temperature vulcanizing silicone rubber, and second seal is formed. By adoption of the combined high-temperature adhesive sealing structure, steam and impurities can be effectively prevented from entering the extra-high-voltage suspension type composite insulator for a long time, and the extra-high-voltage suspension type composite insulator can safely operate.
Description
Technical field
The utility model relates to a kind of ultra high voltage suspended compound insulator gold utensil end combined high-temperature glue sealing structure, belongs to International Classification of Patents H01B technical field.
Background technology
Composite insulator is as the line insulator of a new generation, and with its excellent performance, the use amount in China's electrical network grows with each passing day, and has brought very big benefit for the safe operation of electric power system.But, many problems also appearred in running, and especially the sealing problem of composite insulator end does not cause enough attentions as yet.It possibly be the cause that core brittle fracture and interface puncture, and is a weak spot of the present quality of insulator.Especially in the ultra high voltage field, because the working voltage of insulator is high, Electric Field Distribution is very inhomogeneous, and the field intensity of gold utensil end is higher, and therefore, the quality of insulator hardware end seal performance has very important meaning for the safe operation of insulator.
Summary of the invention
The purpose of the utility model is to provide a kind of suspended compound insulator gold utensil end combined high-temperature glue sealing structure that improves the extra-high voltage combined insulator serviceability, guarantees the safe operation of ultra high voltage insulator.
The purpose of the utility model realizes through following technical scheme.
A kind of ultra high voltage suspended compound insulator gold utensil end combined high-temperature glue sealing structure comprises O-ring seals, has the part such as plug, gold utensil annex, high-temperature silicon disulfide rubber of sheath.End gold utensil annex is connected through crimping with the plug that has sheath; The O-ring seals of two interference fit is housed in the cannelure of end gold utensil annex, and the plug that has sheath inserts wherein; Gold utensil annex and having between the plug of sheath seals with high-temperature silicon disulfide rubber.
This elevated-temperature seal structure of the utility model can stop the entering of aqueous vapor and impurity long-term effectively, guarantees the safe operation of ultra high voltage suspended compound insulator.
Description of drawings
Accompanying drawing is the sketch map of the utility model ultra high voltage suspended compound insulator gold utensil end combined high-temperature glue sealing structure.
Among the figure: 1, O-ring seals, 2, have a plug of sheath, 3, the gold utensil annex, 4, high-temperature silicon disulfide rubber.
Embodiment
Referring to accompanying drawing, ultra high voltage suspended compound insulator gold utensil end combined high-temperature glue sealing structure comprises O-ring seals 1, has plug 2, gold utensil annex 3, high-temperature silicon disulfide rubber 4 of sheath etc.; End gold utensil annex 3 is connected with the plug that has sheath 2 crimping; Two O-ring seals 1 are housed in the cannelure of end gold utensil annex 3, and the plug 2 that be interference fit, has a sheath inserts wherein; Gold utensil annex 3 and having between the plug 2 of sheath with high-temperature silicon disulfide rubber 4 sealings.
End gold utensil annex 3 is connected with the plug that has sheath 2, is to adopt the crimping syndeton, and end gold utensil annex 3 is a permanent seal with being connected of plug 2 sheaths, the carrying out between its connecting portion and atmosphere encapsulation process.End seal adopts high temperature silicon rubber inner and outer sealing combining structure.Before crimping; Two O-ring seals made from the high high-temperature silicon disulfide rubber 4 of gel content 1 between the sheath of, end metal-ware 3 and plug 2, have been placed; Be interference fit, make O-ring seals 1 produce suitable strain, insert the plug 2 that has sheath then; Through twice crimping, form the sealing of first road.At last, at gold utensil annex 3 and have between the plug 2 of sheath, form the sealing of second road with the high-temperature silicon disulfide rubber sealing.Carry out outside high-temp glue sealing at last.This with the knockdown hermetically-sealed construction of high-temp glue inner and outer sealing, can stop the entering of aqueous vapor and impurity long-term effectively, guarantee the safe operation of ultra high voltage suspended compound insulator.The utility model product structure is reasonable, and feasible process is economical and practical.
