Abstract

The utility model relates to a transformer winding, including the wire, the conductor cross section shape be the I shape, there is the notch in the cross -section both sides, the inseparable coiling of wire forms the winding on the iron core surface, the notch of adjacent wire combines to form the water route, between winding and the iron core, all be provided with the water barrier between every layer of winding, the water route be provided with the delivery port, the delivery port runs through outside to the winding. The utility model discloses a transformer winding is with low costs, and the water route is blockked up the back and is easily handled.

Description

A kind of Transformer Winding
Technical field
The utility model relates to a kind of Transformer Winding, belongs to field of electrical equipment.
Background technology
Transformer Winding can produce heat owing to being in operation, and needs to consider heat radiation, especially high-power transformer during design, and the heat of generation is comparatively large, if it is bad to dispel the heat, during operation, temperature raises, and causes transformer damage most probably, even causes fire.Transformer Winding of the prior art all adopts the coiling of rectangle copper pipe to form, and be water route in the copper pipe of hollow, pass into cooling water and cool Transformer Winding, Problems existing is that rectangle copper pipe cost is higher, and extremely difficulty eliminating after the problems such as blocking appears in water route.
Summary of the invention
For solving the problem, the utility model provides a kind of Transformer Winding, and concrete scheme is:
A kind of Transformer Winding, comprise wire, described conductor cross-section shape is I shape, and both sides, cross section exist notch, and wire is closely wound on iron core surface and forms winding, and the notch of adjacent wires combines and forms water route; Between winding and iron core, every layer of winding surface be provided with water barrier; Described water route is provided with delivery port, and delivery port is through to winding outside.
Further, described water barrier is resin-cast layer or marine glue belt.
Further, the notch shape of described I shape wire is rectangle or arc.
Further, described iron core is the superposition of multilayer silicon steel sheet.
The I shape wire coiling of winding in the utility model, relative to traditional copper pipe winding, cost is lower, and combines by the notch of adjacent wires the water route formed, and also conveniently dredges after there is blocking.
Accompanying drawing explanation
Fig. 1 is profile of the present utility model;
Fig. 2 is sectional view of the present utility model.
Embodiment
A kind of Transformer Winding as shown in Figure 1, 2, comprises wire 1, and described wire 1 cross sectional shape is I shape, and both sides, cross section exist notch, and wire 1 is closely wound on iron core 5 surface and forms winding, and the notch of adjacent wires combines and forms water route 2; Between winding and iron core 5, the surface of every layer of winding is provided with water barrier 4; Described water route 2 is provided with delivery port 3, and delivery port 3 is through to winding outside.
Water barrier 4 described in the present embodiment is resin-cast layer or marine glue belt, and the notch shape of described I shape wire 1 is rectangle or arc, and described iron core 5 is the superposition of multilayer silicon steel sheet.
The I shape wire coiling of winding in the utility model, relative to traditional copper pipe winding, cost is lower, and combines by the notch of adjacent wires the water route formed, and also conveniently dredges after there is blocking.
