Description
Technical field
The present invention relates to the structure of transformer, specifically is a kind of tangible waterproof full-shield transformer.
Background technology
Transformer is present quite common electric power, electronic building brick, can change the size of voltage, be mainly used in the electrical equipment such as power transmission and transformation, illumination, Switching Power Supply, the transformer that occurs now on the market is when being subjected to than big bang, magnetic core and skeleton will be clashed into, cause the circuit of magnetic core to occur damaging, and then influence the performance of transformer.Influence the performance of transformer when shaking in order to reduce, people fill fixing glue and epoxy resin in the place, slit between magnetic core and skeleton, add stiff stability and insulation function.Specifically can participate in publication number CN 101651018A, a kind of improved transformer structure discloses a kind of one deck that is provided with exactly and has played sealing and the fixing glue of buffering effect as filler between magnetic core and skeleton, increase stability.Because the insulation property of fixing glue are bad, often do not have the effect that insulation is isolated.Though the insulating properties of epoxy resin is relatively good, epoxy resin can follow a lot of bubbles to produce, and bubble can be present in the epoxy resin always, causes sealing not strong when filling.Therefore well address this problem and just seem particularly important.
Further also can find out from the structure of transformer inside, at outside high-tension coil and the low-voltage coil of twining of the magnetic core of transformer, each high-tension coil and low-voltage coil join with high-tension electricity outlet, low tension outlet respectively, when between coil lead and transformer outlet, connecting, adopt forms such as crimping, welding, riveted joint to be connected with the mode of connection according to the quantity of transformer interior loop, lead-in wire is set directly in the insulating barrier.Isolating seal by insulating barrier reaches the insulation purpose, but in actual use, complicated lead-in wire can produce strange change and most advanced and sophisticated high voltage electric field, the phenomenon that partial discharge produces spark can take place, insulating barrier is burnt in serious meeting, causes whole transformer not use, inconvenience very.
Summary of the invention
Technical problem solved by the invention is to provide a kind of Stability Analysis of Structures, and the life-span is long, the tangible widely type waterproof of use face full-shield transformer.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of tangible type waterproof full-shield transformer, the center is a transformer core, being arranged on based on ethylene-propylene diene copolymer is in the semiconductor exterior shield layer shell made of the macromolecule modified renewable reusable environment-friendly materials of main body, twine high-tension coil and low-voltage coil in the outside of transformer core, with described high-tension coil and low-voltage coil by lead-in wire and high potential cable termination being set and the low-voltage cable plug joins, described high-tension coil, after low-voltage coil is wrapped in the outside of transformer core, and to fill ethylene-propylene diene copolymer in the space between the screen shell be that the macromolecule modified renewable reusable environment-friendly materials of main body are made the insulating barrier with all insulation, described insulating barrier wraps high-tension coil lead-in wire and low-voltage coil lead-in wire fully, outside described lead-in wire stube cable plug and coil, and one deck also is set between the insulating barrier is the semiconductor leads screen that the macromolecule modified renewable reusable environment-friendly materials of main body are made based on ethylene-propylene diene copolymer.
Described exterior shield layer can touch at any position of transformer outside, and the phenomenon of getting an electric shock can not occur at transformer external overall bonding.
The present invention in use, being provided for of lead-in wire screen avoids the strange change that produces on the high-voltage connection partial discharge phenomenon generation spark to occur with most advanced and sophisticated high voltage electric field, influences the use of transformer.
In the present invention, lead-in wire is outer, and one deck is set is that the semiconductor leads screen that the macromolecule modified renewable reusable environment-friendly materials of main body are made is not only applicable to transformer industry based on ethylene-propylene diene copolymer, and in other high-voltage assembly, all can use when connecting as long as relate to cable joint or go between.The various instrument transformers, the high-tension coil that further are applied in the same operation principle of transformer can reach same effect.
The invention has the beneficial effects as follows because after the transformer integral sealing insulation processing, it is outside that to adopt based on ethylene-propylene diene copolymer be the semiconductor exterior shield layer that the macromolecule modified renewable reusable environment-friendly materials of main body are made, fill ethylene-propylene diene copolymer in inside and be the macromolecule modified renewable reusable environment-friendly materials of main body and make insulating barrier with all insulation, with being provided with based on ethylene-propylene diene copolymer outside inner lead is the semiconductor leads screen that the macromolecule modified renewable reusable environment-friendly materials of main body are made, make not only integral sealing of transformer, insulation, and stable performance in use, can use for a long time out of doors, in the underground and water, applicable surface is very wide.
