The utility model discloses an insulating case for a power electronic transformer, which comprises a case made of glass fiber reinforced plastics and embedded parts arranged on the case for installing other equipment. Each surface of the case is The package has an interlayer made of NOMEX cardboard. The insulating shell of the utility model is made of NOMEX cardboard sandwiched in glass fiber reinforced plastics. The unique material and structure make the insulating shell have better high voltage resistance performance than the existing insulating shell. The embedded parts are made of non-metallic parts, which improves the insulation performance on the one hand; on the other hand, greatly reduces the overall weight of the insulating shell.
Description
Technical field
The utility model belongs to field of track traffic, and in particular to a kind of electric power electric transformer for EMU it is exhausted
Edge shell.
Background technology
The insulation shell for being presently used for EMU electric power electric transformer is generally made of glass-reinforced plastic material, and glass is being pasted
Pre-embedding metal part ultimately forms the insulation shell with built-in fitting for installing other equipment during glass steel.It is actually using
In the process, there are following defects：
1. although glass-reinforced plastic material has insulation performance, 30,000 volts of pressure resistances are generally can only achieve, if there is requirements at the higher level
Insulating properties, this kind of insulation shell are difficult to reach requirement.For example, need to produce the insulation shell that disclosure satisfy that 60,000 volts of requirements above at present,
The prior art is difficult to accomplish.
2. built-in fitting is metal, on the one hand since metal is conductor, cause product insulation performance poor, proof voltage can be compared with
It is low；On the other hand, metal quality weight considerably increases the overall weight of insulation shell.
NOMEX cardboards involved in this case are a kind of aromatic polyester amine polymers of synthesis, are that E.I.Du Pont Company is practical new
Type is created and can when it is processed into various paper kenels in a kind of nineteen sixty-five commercialized scientific and technological heat resistanceheat resistant insulating materials
Fabulous motor, chemistry and mechanical integrity are provided.
Gel coat（English name gel coat）, it is unsaturated polyester (UP)（UP）Made of the dispersions such as middle addition pigment and thixotropic agent
Fiberglass（FRP）And the coloring thixotropy product that table top finishing coat is used for developing.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide a kind of becoming for power electronics with better insulation performance
The insulation shell of depressor.
The technical solution that the utility model solves the problems, such as is：A kind of insulation shell for electric power electric transformer, including glass
Shell made of glass steel and the built-in fitting for installing other equipment on shell, each face Jun Bao of the shell
It is wrapped with interlayer made of NOMEX cardboards.
Interlayer made of NOMEX cardboards is set in said program in shell, since NOMEX cardboards have excellent insulation
Performance, it is more preferable than the insulation performance of glass-reinforced plastic material so as to can only achieve the shell of 30,000 volts of voltage endurance capabilities originally, it now is possible to
60,000 volts of voltage endurance capability are reached
Preferably, the built-in fitting is made of nylon material.The built-in fitting of this kind of material is first very light, is second insulation
Body, insulation performance are better than metal.
Preferably, the shell length is 2.9~3.5m, and the thickness of interlayer is 0.5~1mm.
The remarkable result of the utility model is：
1. insulation shell is made of fiberglass inner clip NOMEX cardboards, unique material and structure make insulation shell relative to existing
Insulation shell for there is better high pressure resistant electrical property.
2. built-in fitting is made of nonmetal parts, insulation performance is on the one hand improved；On the other hand, insulation is greatly reduced
The overall weight of shell.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the utility model insulation shell structural schematic diagram.
In figure：1- shells, 2- built-in fittings, 3- interlayers.
Specific implementation mode
As shown in Figure 1, a kind of insulation shell for electric power electric transformer, including shell 1, Yi Jishe made of fiberglass
In the nylon material built-in fitting 2 for installing other equipment on shell 1.Each face of the shell 1, which is wrapped up, to be equipped with
Interlayer 3 made of NOMEX cardboards.
1 length of the shell is 2.9~3.5m, and 3 thickness of the interlayer is 0.5~1mm.
Processing method includes the following steps：
（a）Die surface is cleaned out, coating release agent, later in the uniform glue spraying clothing of die surface.
（b）On gel coat, glass cloth is pasted layer by layer, is bonded NOMEX cardboards and built-in fitting before reaching preset thickness
On glass cloth.
（c）Continuation pastes glass cloth again until design thickness so that NOMEX cardboards are wrapped in interior, built-in fitting 2 by glass cloth
It is partially submerged into glass cloth, partial denudation is outside.
（d）Product is vacuum-treated immediately after pasting.
（e）Demoulding can be obtained insulation shell product.
