For switch, use into and out of for line hollow porcelain insulator, the equal mucilage binding of its upper and lower end has metal-ware, and the internal pressure of this series products (hydraulic pressure) test method is very ripe.The method utilizes the metal-ware of insulator upper and lower end mucilage binding to be directly connected with hydraulic pressure frock, forms confined space, by water pressure engine, makes this space internal pressure arrive trial value.Along with the continuous upgrading of hollow porcelain insulator product, the production difficulty of ultra-large type electroceramics is large, and the factor that affects product quality is many, so ultra-large type electrotechnical porcelain product carries out hydraulic pressure resistance test in routine, to guarantee the quality of voltage levels insulator product.There are a lot of difficult problems in process of the test, wherein the hydraulic testing of ultra-large type hollow porcelain insulator is because product height is high, the upper end of product does not have mucilage binding metal-ware, there is certain difficulty in its sealing, difficulty is mainly manifested in the connected mode of closed cover and product ontology, cannot directly be connected with flange and realize sealing by hydraulic pressure frock, make the sealed at both ends difficulty of insulator, cause the hydraulic testing to be difficult to realize.
Utility model content
The purpose of this utility model is to provide a kind of ultra-large type hollow porcelain insulator water test unit, and solving upper end does not have the ultra-large type hollow porcelain insulator hydraulic testing of mucilage binding metal-ware to be difficult to the problem realizing.
To achieve these goals, the utility model adopts following technical scheme:
A kind of ultra-large type hollow porcelain insulator water test unit, comprise for sealing the top cover labyrinth plate of porcelain insulator upper port, for connecting the lower seal cover plate of porcelain insulator lower end metal-ware, top cover labyrinth plate and lower seal cover plate are fixed by many cylinder lever connecting rod tractives, make upper and lower seal cover board that porcelain insulator is sealed at both ends.
Also comprise transition connecting plate, upper and lower seal cover board is fixed by many cylinder lever connecting rods and transition connecting plate respectively, by transition connecting plate, upper and lower seal cover board is linked together.
Described top cover labyrinth plate bottom is provided with the depression adapting with porcelain insulator upper port shape.
Between described top cover labyrinth plate and porcelain insulator upper port, be provided with O-ring seal, between lower seal cover plate and porcelain insulator lower end metal-ware, be provided with O-ring seal.
Described lower seal cover plate is connected with porcelain insulator lower end metal-ware by bolt
The utility model is sealed at both ends by porcelain insulator by upper and lower seal cover board, upper and lower seal cover board is fixed by many cylinder lever connecting rod tractives, the lower ending opening of product adopts traditional sealing method to seal with the mode that porcelain insulator lower end metal-ware is connected with lower seal cover plate, upper and lower seal cover board is pressed on porcelain insulator upper port realization sealing by many cylinder lever connecting rod tractives are fixing by top cover labyrinth plate, make ultra-large type hollow porcelain insulator uniform stressed in test, hydraulic testing process is completed smoothly.
