Abstract
The utility model provides a kind of seal of dry high voltage casing.Insulation for existing dry sleeve has mould complexity, and the process-cycle is long, the problem general, versatility is extremely low.The seal of dry high voltage casing of the present utility model, it is characterized in that: comprise the hollow combined insulator or porcelain insulator that are arranged on sleeving core external body, the flange of described hollow combined insulator or one end of porcelain insulator is connected with the connection seat be arranged on sleeve pipe core body, the flange of described hollow combined insulator or the other end of porcelain insulator is connected with the ring flange being arranged on sleeving core external body, described hollow combined insulator or be filled with insulating medium layer between porcelain insulator and described sleeve pipe core body.The utility model is lightweight, without revealing, can monitor, multipurpose.
Description
technical field:
The utility model relates to a kind of seal of dry high voltage casing, belongs to electric sleeve technology field.
background technology:
Current sleeve pipe insulation system is single, oilpaper cover pipe insulation mainly oilpaper electroceramics formula structure, dry sleeve is composite silicone rubber and electroceramics formula structure mainly, these traditional insulation systems also exist some shortcomings part, as: oilpaper electric capacity electroceramics formula complex structure is heavy, and also exist easily occur reveal, need periodic maintenance, the deficiencies such as the single shortage monitoring port of service condition; The conventional composite insulation mould of dry sleeve is complicated, and the process-cycle is long, must a size full skirt correspondence core diameter, general, versatility is extremely low.
summary of the invention:
The purpose of this utility model is the seal providing a kind of dry high voltage casing for above-mentioned Problems existing, not only simply light, and solve easily occur reveal, the scope of application is little, cannot monitor, the problems such as being common to property is low.
Above-mentioned object is realized by following technical scheme:
The seal of dry high voltage casing, comprise the hollow combined insulator or porcelain insulator that are arranged on sleeving core external body, the flange of described hollow combined insulator or one end of porcelain insulator is connected with the connection seat be arranged on sleeve pipe core body, the flange of described hollow combined insulator or the other end of porcelain insulator is connected with the ring flange being arranged on sleeving core external body, described hollow combined insulator or be filled with insulating medium layer between porcelain insulator and described sleeve pipe core body.
The seal of described dry high voltage casing, described hollow combined insulator or be provided with O RunddichtringO and flat seal between the flange of porcelain insulator and described connection seat.
The seal of described dry high voltage casing, is also provided with O RunddichtringO and flat seal between the ring flange of described hollow combined insulator or the flange of porcelain insulator and described sleeving core external body.
The seal of described dry high voltage casing, the ring flange of described sleeving core external body is provided with for filling the screwed hole changing dielectric.
The seal of described dry high voltage casing, the flange of described hollow combined insulator or porcelain insulator both sides is connected respectively by bolt with between described connection seat and the ring flange of described sleeving core external body.
Beneficial effect:
This practical insulating dielectric materials can not be revealed, and the core diameter of the inside can have certain adjustment within the scope of insulating bore outside, can realize multiplex, thus reach sleeve pipe insulation system lightweight, without revealing, can monitor, multiduty object.And this structure has dropped into actual mass production, to produce, quick and easy for installation, safe and reliable to operation, insulation property are good.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, sleeve pipe core body; 2, hollow combined insulator or porcelain insulator; 3, connection seat; 4, ring flange; 5, insulating medium layer; 6, O RunddichtringO; 7, flat seal; 8, screwed hole; 9, bolt.
embodiment:
As shown in Figure 1: the seal of the dry high voltage casing of the present embodiment, comprise the hollow combined insulator or porcelain insulator 2 that are arranged on sleeve pipe core body 1 outside, the flange of described hollow combined insulator or one end of porcelain insulator is connected with the connection seat 3 be arranged on sleeve pipe core body, the flange of described hollow combined insulator or the other end of porcelain insulator is connected with the ring flange 4 being arranged on sleeving core external body, described hollow combined insulator or be filled with insulating medium layer 5 between porcelain insulator and described sleeve pipe core body.Described hollow combined insulator or be provided with O RunddichtringO 6 and flat seal 7 between the flange of porcelain insulator and described connection seat.Also O RunddichtringO and flat seal is provided with between the ring flange of described hollow combined insulator or the flange of porcelain insulator and described sleeving core external body.The ring flange of described sleeving core external body is provided with for filling the screwed hole 8 changing dielectric.The flange of described hollow combined insulator or porcelain insulator both sides is connected respectively by bolt 9 with between described connection seat and the ring flange of described sleeving core external body.First rely on high-strength bolt by firm for the Flange joint of connection seat and hollow combined insulator or porcelain insulator in the process of installing, and sealing ring is compressed, easy for installation and connect reliable, the flange of hollow combined insulator or the porcelain insulator other end and the ring flange that is arranged on sleeving core external body are fixed and by O RunddichtringO and flat seal sealing by same employing bolt, the interchangeability and the processing that improve metalwork are convenient, O-ring seals, flat seal together constitutes the hermetically-sealed construction of hollow combined insulator or porcelain insulator and sleeve pipe core body, bolt is relied on to provide thrust, ensure that sealing is reliable, ring flange arranges screwed hole, dielectric can be filled by screwed hole.And dielectric can be changed easily.Screwed hole can also use as the reserved mouth that detects, and total has the features such as excellent insulating property, quality are light, easy to process, multipurpose.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises and is equal to by above technical characteristic the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to the common practise of those skilled in the art.
