Description
Technical field
The utility model relates to power domain, is specifically related to a kind of transformer with electrical insulation sheet for power domain.
Background technology
Transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, and be the important force device changing electric pressure in electric power system, the safe and stable operation of transformer, has self-evident importance to electric power system.
Transformer, when producing installation, can be subject to very large active force between all parts, so usually arrange elasticity electrical insulation sheet between iron core and coil, between each layer conductor of coil, prevents insulation impaired.But based on the consideration of thermodynamic property and cost, electrical insulation sheet is all thinner and two sides is smooth flat, and such electrical insulation sheet just cannot play a very good protection.
Utility model content
For the problems referred to above, the utility model provides a kind of transformer with electrical insulation sheet for power domain.
The purpose of this utility model realizes by the following technical solutions:
A kind of transformer with electrical insulation sheet for power domain, comprise iron core, exterior loop, interior loop, the secondary insulation joint end being positioned at the main insulation terminals above described transformer and being positioned at below described transformer, the described interior loop be made up of multi-layer conductor leads and described exterior loop are wrapped in outside described iron core, described interior loop is between described iron core and described exterior loop, described main insulation terminals are connected with described interior loop, described secondary insulation joint end is connected with described exterior loop, it is characterized in that, between described iron core and described interior loop, between the described wire of each layer of described interior loop, between described exterior loop and described interior loop, the electrical insulation sheet be made up of electrical insulating material for the protection of isolation is provided with between the described wire of each layer of described exterior loop, described electrical insulation sheet is provided with the rib be made up of elastomeric material.Preferably, the one side of described electrical insulation sheet arranges rib, and another side is smooth flat.
Preferably, described electrical insulation sheet is square laminated structure.
Preferably, the cross section of described rib is square.
Preferably, the base vertical of described rib and described electrical insulation sheet.
The beneficial effects of the utility model are: owing to being provided with rib in electrical insulation sheet; interval during installation between iron core and coil, between each layer conductor of coil is strengthened; when not increasing electrical insulation sheet basal plane thickness, greatly strengthen the ability of electrical insulation sheet protection insulation.
