Abstract
The invention discloses a silicon rubber outlet sleeve applied on a high-voltage capacitor. The silicon rubber outlet sleeve applied on the high-voltage capacitor is obtained through connecting a ceramic core body and metal connectors at two ends of the ceramic core body. The ceramic core body is composed of a hollow ceramic core rod and a silicon rubber skirt sheath which seamlessly coats the hollow ceramic core rod. According to the silicon rubber outlet sleeve applied on the high-voltage capacitor, only the rod of the ceramic core body is made of ceramic and furthermore the rod is hollow, thereby greatly reducing consumption of rare earth and furthermore keeping an oil filling characteristic in the capacitor. According to the silicon rubber outlet sleeve, the silicon rubber skirt sheath is used so that the sleeve has excellent hydrophobicity and long service life. In summary, the sleeve of the invention has advantages of improving pollution resistance, greatly reducing product weight, realizing no requirement for room temperature vulcanized silicone rubber (RTV) spraying in a traditional pure ceramic sleeve, reducing use cost and maintenance cost of a power line, reducing loss of national rare earth, and furthermore realizing convenient mounting and no requirement for maintenance.
Description
Technical field
The present invention relates to the outlet casing tube being applied to high-voltage capacitor, particularly a kind of silicon rubber outlet casing tube being applied to high-voltage capacitor.
Background technology
At present, the porcelain condenser that porcelain core and full skirt are formed in one appears that sleeve pipe is pure porcelain casing tube, in the capacitor that the whole world uses.Its shortcoming is that dust dirt is easily piled up in porcelain surface, reduces electrical property.For improving the hydrophobicity of porcelain full skirt, most of producer needs at porcelain full skirt surface spraying RTV glue-line, greatly increases the cost of distribution system.Traditional porcelain condenser uses a large amount of rare soil, does not also have benefit like this to territory soil protection.In addition, external a few large capacitor producer in China's buying, is exactly all the loss of the rare soil in order to avoid itself.Traditional porcelain condenser sleeve pipe RTV layer will be dismantled from new spraying in 3 ~ 5 years service time, which increased the maintenance cost of electric power system.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency existing in prior art, a kind of silicon rubber outlet casing tube being applied to high-voltage capacitor is provided.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of silicon rubber outlet casing tube being applied to high-voltage capacitor, be formed by connecting by the metal connecting piece at porcelain core body and described porcelain core body two ends, described porcelain core body is made up of hollow porcelain core barred body and the seamless coated silicon rubber umbrella skirt sheath of described hollow porcelain core rod external body.
As preferably, hollow porcelain core rod external use silicon rubber umbrella skirt sheath.
As preferably, above-mentioned hollow porcelain core barred body and silicon rubber umbrella skirt sheath adopt adhesive to carry out bonding connection.
As preferably, above-mentioned metal connecting piece is preferably flange.
Compared with prior art, beneficial effect of the present invention: the present invention is applied to the silicon rubber outlet casing tube of high-voltage capacitor, porcelain core body only barred body uses porcelain, and barred body is hollow, substantially reduce the number the use of rare soil, the characteristic of retention capacitor inside punching oil use simultaneously: the present invention adopts silicon rubber umbrella skirt sheath, makes sleeve pipe of the present invention have good hydrophobicity, long service life; Generally speaking, sleeve pipe of the present invention can improve stain resistance, greatly reduces product weight, without the need to spraying RTV glue as traditional pure porcelain casing tube, reduces power line use cost and maintenance cost, reduces state-owned rare soil losses, and installs light, release maintenance.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the embodiment of the present invention 1.
Embodiment
Below in conjunction with test example and embodiment, the present invention is described in further detail.But this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following embodiment, all technology realized based on content of the present invention all belong to scope of the present invention.
Embodiment 1 is with reference to Fig. 1, a kind of silicon rubber outlet casing tube being applied to high-voltage capacitor, be formed by connecting by the metal connecting piece 2 at porcelain core body 1 and porcelain core body 1 two ends, porcelain core body 1 is made up of hollow porcelain core barred body 11 and the outside seamless coated silicon rubber umbrella skirt sheath 12 of hollow porcelain core barred body 11; Hollow porcelain core barred body 11 and silicon rubber umbrella skirt sheath 12 adopt adhesive to carry out bonding connection; Metal connecting piece 2 is flange.
Between this routine hollow porcelain core barred body 11 and silicon rubber umbrella skirt sheath 12 be connected to production time, first silicon rubber umbrella skirt jacket mould sulfidization molding silicon rubber umbrella skirt sheath 12 is adopted, again by adhesive uniform treatment on hollow porcelain core porcelain rod 11, then silicon rubber umbrella skirt sheath 12 is enclosed within hollow porcelain core rod 11, carries out cold curing.
Claims (3)
1. one kind is applied to the silicon rubber outlet casing tube of high-voltage capacitor, it is characterized in that, be formed by connecting by the metal connecting piece at porcelain core body and described porcelain core body two ends, described porcelain core body is made up of hollow porcelain core barred body and the seamless coated silicon rubber umbrella skirt sheath of described hollow porcelain core rod external body.
