Abstract
The invention discloses the glue sealing method in a kind of superhigh pressure polymeric housed metal oxide arrester end, comprise the following steps: first lightning arrester core body is loaded in insulating cylinder; Again lightning arrester end upper flange is connected with insulating cylinder upper end, mucilage binding, lightning arrester end lower flange to be connected with insulating cylinder lower end, mucilage binding; And then at the outer surface molding silicone rubber overcoat of lightning arrester end upper flange, lower flange and insulating cylinder.The present invention adopts a glue sealing method, it effectively can improve the sealing property at lightning arrester end flange and silicon rubber interface, can stand the erosion of external environment condition for a long time, and the encapsulating of end flange can reduce local field strength, reduce the impact that galvanic corrosion is damaged, improve the reliability of product.
Description
Technical field
The present invention relates to lightning arrester and manufacture field, the particularly glue sealing method in a kind of superhigh pressure polymeric housed metal oxide arrester end.
Background technology
Polymeric housed metal oxide arrester is made up of lightning arrester core body, silastic material, insulating cylinder and upper lower flange.Domestic existing superhigh pressure polymeric housed metal oxide arrester forming technique is first at the shaping external insulation umbrella cover of insulating cylinder outer surface, and then load lightning arrester core body, connect lower flange respectively at the upper and lower side of composite sheath insulating cylinder again, secondary sealing is carried out to the faying face of upper lower flange and overcoat.Because this method first carries out connecting and sealing after shaping umbrella cover again, so always have gap between the external insulation umbrella cover of polymeric housed metal oxide arrester and flange, secondary sealing is needed to fill up this gap.Prior art exists that flange seal performance is bad, and local field is powerful, weatherability and anti creepage trace poor, and presentation quality is bad, affects reliability and the useful life of polymeric housed metal oxide arrester.
Summary of the invention
The object of the present invention is to provide the glue sealing method in a kind of superhigh pressure polymeric housed metal oxide arrester end, it effectively can improve the sealing property at lightning arrester end flange and silicon rubber interface, the erosion of external environment condition can be stood for a long time, and the encapsulating of end flange can reduce local field strength, reduce the impact that galvanic corrosion is damaged, improve the reliability of product.
For reaching above object, the present invention takes following technical scheme to be achieved:
One time, superhigh pressure polymeric housed metal oxide arrester end glue sealing method, comprises the following steps: first load in insulating cylinder by lightning arrester core body; Again lightning arrester end upper flange is connected with insulating cylinder upper end, mucilage binding, lightning arrester end lower flange to be connected with insulating cylinder lower end, mucilage binding; And then at the outer surface molding silicone rubber overcoat of lightning arrester end upper flange, lower flange and insulating cylinder.
The present invention further improves and is: molding silicone rubber overcoat adopts general injection technique, sulfidization molding makes the silicon rubber of injection form an entirety simultaneously, forming temperature is 110 DEG C ~ 115 DEG C, and briquetting pressure is 15MPa ~ 20MPa, and molding time is 55 minutes ~ 60 minutes.
The present invention further improves and is: the seam crossing of the coated upper flange of silastic material, lower flange and insulating cylinder.
The present invention further improves and is: the periphery of upper flange and lower flange is provided with a circle and caves in, and this caves in and to be filled and led up by silastic material.
The present invention further improves and is: insulating cylinder adopts epoxy fibreglass to make.
The present invention further improves and is: upper flange and lower flange adopt carbon steel or aluminium alloy to make.
The present invention further improves and is: periphery, upper flange coated insulation cylinder upper end, lower flange wrap insulate cylinder lower end periphery.
Relative to prior art, the present invention has following beneficial effect: the present invention adopts a glue sealing method, it effectively can improve the sealing property at lightning arrester end flange and silicon rubber interface, the erosion of external environment condition can be stood for a long time, and the encapsulating of end flange can reduce local field strength, reduce the impact that galvanic corrosion is damaged, improve the reliability of product.
Accompanying drawing explanation
The structural representation of the superhigh pressure polymeric housed metal oxide arrester of Fig. 1 prepared by the inventive method;
In figure: 1, upper flange; 2, silastic material; 3, insulating cylinder; 4, lightning arrester core body; 5, lower flange.
Embodiment
With reference to shown in Fig. 1, the superhigh pressure polymeric housed metal oxide arrester prepared by the inventive method, is made up of lightning arrester core body 4, silastic material 2, insulating cylinder 3, upper flange 1 and lower flange 5.Silicon rubber, when silastic material 2 is shaping, is expelled to the outer surface of insulating cylinder 3 and end flange part (upper flange 1 and lower flange 5) by the end of polymeric housed metal oxide arrester, and sulfidization molding, makes the silastic material of injection form an entirety simultaneously.Insulating cylinder 3 adopts epoxy fibreglass to make; Upper flange 1 and lower flange 5 adopt carbon steel or aluminium alloy to make;
A kind of one time, superhigh pressure polymeric housed metal oxide arrester end of the present invention glue sealing method, specifically comprise the following steps: first lightning arrester core body 4 is loaded in insulating cylinder 3, again lightning arrester end upper flange 1 is connected with insulating cylinder 3 upper end, mucilage binding, lightning arrester end lower flange 5 is connected with insulating cylinder 3 lower end, mucilage binding, and then at lightning arrester end upper flange 1, the outer surface molding silicone rubber overcoat 2 of lower flange 5 and insulating cylinder 3, molding silicone rubber overcoat 2 adopts general injection technique, sulfidization molding makes the silicon rubber of injection form an entirety simultaneously, forming temperature is 110 DEG C ~ 115 DEG C, briquetting pressure is 15MPa ~ 20MPa, molding time is 55 minutes ~ 60 minutes.The periphery of upper flange 1 and lower flange 5 is provided with a circle and caves in, and this is interior when being trapped in sulfidization molding, and by silicon rubber filling, shaping rear silicon rubber fills up and caves in, and the flush with outer surface with upper flange 1 and lower flange 5, can stand the erosion of external environment condition for a long time and should not come off.The present invention adopts a glue sealing method, it effectively can improve the sealing property at lightning arrester end flange and silicon rubber interface, can stand the erosion of external environment condition for a long time, and the encapsulating of end flange can reduce local field strength, reduce the impact that galvanic corrosion is damaged, improve the reliability of product.
