Abstract
A kind of mould for sample needed for the experiment of casting epoxy resin composite corona, belong to high-voltage isulation research field.The utility model includes teeming stage, cast steel ring and fixed support.There are four toroidal cavities for being used for fixed cast steel ring on teeming stage, respectively have a sample preparation platform for being used to pour into a mould sample on the inside of each groove, and there are four screws for the support that is connected.It is identical with toroidal cavity inner and outer diameter to pour into a mould steel ring inner and outer diameter, is securable in groove, and can be according to the cast steel ring of the different choice proper height of required sample thickness.Fixed support is made up of four screws, and is fixed by nut.Bright spot of the present utility model is that the mould can pour into a mould the epoxy resin composite material disk sample tested for corona, can easily control the thickness of cast by selecting the cast steel ring of different height.And a platform can make four samples simultaneously, sample preparation rate is high.Further, the utility model teeming stage material is mould steel, and its resistance to elevated temperatures and wearability are good.
Description
Technical field
The mould of the cast sample of epoxy resin needle plate electrode is the utility model is related to, belongs to high-voltage isulation research field.
Background technology
Nowadays China's rapid economic development, many industry power consumptions improve year by year, and the voltage class of electrical equipment is also continuous
Improve, higher requirement is proposed to the dielectric properties of the epoxy resin insulation material used in high-tension power transmission and transformation equipment, in epoxy
Proper amount of nano filler is added in resin can improve its dielectric properties, and need to prepare the disc shaped test piece of small size in the experimental stage
Its dielectric properties of progress corona experiment test.
It is traditionally used for the problems of mould of casting epoxy resin composite corona experimental sample：
1) teeming stage of suitable dimension is lacked, obtained sample size can not meet corona experimental provision requirement.
2) traditional moulds sample preparation rate is low, need to repeatedly carry out sample making course, causes sample preparation short time consumption to be grown.
3) during cast, the thickness of uncontrollable sample, it is impossible to meet the requirement that becomes more meticulous of experiment.
4) mould can not adjust level, cause obtained sample thickness uneven, it is impossible to meet experimental facilities to sample
Size requirement.
As can be seen here, the casting mold sample preparation precision of sample needed for epoxy resin composite material corona traditional at present experiment
Not enough, qualification rate is not high, has a significant impact to the test of further dielectric properties.
The content of the invention
