Abstract
The utility model relates to a paper insulation transformer winding wire turn insulation structure and belongs to the field of transformer technology. The paper insulation transformer winding wire turn insulation structure comprises a wire body (3), reinforced insulation wires (1), and ordinary insulation wires (2). The reinforced insulation wires are disposed at two ends of the wire body, and the ordinary insulation wires are disposed on the other parts of the wire body. A manufacture method of the paper insulation transformer winding wire turn insulation structure comprises the steps of making a wire with a fixed length required by a coil from a piece of wire, calculating a length of a reinforcing pie and an extension required by each end, and making the wire in the range of the length into reinforced insulation and making the other parts of the wire into ordinary insulation. The paper insulation transformer winding wire turn insulation structure improves production efficiency greatly, requires no separate production of the reinforced insulation wires and the ordinary insulation wires during production, requires no independent winding process during the manufacture of a winding, and avoids vulnerable insulation points caused by welding on wire changing positions of different insulation wires in a conventional structure, thereby improving insulation property of the winding greatly.
Description
Technical field
The utility model relates to a kind of paper insulation Transformer Winding conductor turns insulation system, belongs to the transformer technology field.
Background technology
H level NOMEX paper insulation distribution becomes the general pie winding structure that adopts, because winding is in the barred window, the winding upper and lower end parts can be closer apart from last lower yoke distance, therefore, be to guarantee the dielectric voltage withstand experimental performance, the some line cakes in end adopt the reinforcement of insulating of the mode of strengthening turn insulation.The reinforcement turn insulation mode of background technology is that lead is made two kinds, it is a kind of common insulation, a kind of reinforced insulation, the line cake that the end need be strengthened when coil winding uses the reinforced insulation lead, middle part line cake adopts common insulated conductor, this fewer owing to the end employed lead of line cake in production reality, be unfavorable for the large-scale production of lead manufacturer.
The utility model content
The purpose of this utility model provides a kind of paper insulation Transformer Winding conductor turns insulation system, reinforced insulation part lead can be with whole winding lead large-scale production together when lead is produced, when the Transformer Winding coiling, can avoid solder joint occurring at end line feeder cake and common insulated wire cake junction, the reinforced insulation performance solves the problems referred to above that background technology exists.
The technical solution of the utility model is:
A kind of paper insulation Transformer Winding conductor turns insulation system comprises wire body, lead reinforced insulation, the common insulation of lead, in two ends of wire body the lead reinforced insulation is set, and remainder is provided with the common insulation of lead.
When making the utility model, a required lead fixed length of coil is made on the lead, calculates the end and need strengthen cake and end and lift one's head length, the lead of this length range is made reinforced insulation, remainder is made conventional insulation.
After finishing the calculating of transformer electromagnetism, further calculate required lead length overall of each line cake and coil and lift one's head length from beginning to end, calculate the length that needs reinforced insulation on the whole lead thus, when producing, lead, carries out in strict accordance with the figure paper size during coil winding in strict accordance with the wrapping of insulating of this length.
Good effect of the present utility model is: this conductor turns insulation system has improved production efficiency greatly, in the lead production process, do not need again reinforced insulation lead and common insulated conductor to be produced respectively, in the winding technique process, do not need independent coiling yet, before having avoided simultaneously in the structure thread-changing place of different insulative lead improved the insulation property of winding greatly because of the insulation weak spot that welding causes.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram;
Among the figure: lead reinforced insulation 1, the common insulation 2 of lead, wire body 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further by embodiment.
A kind of paper insulation Transformer Winding conductor turns insulation system comprises wire body 3, lead reinforced insulation 1, the common insulation 2 of lead, in two ends of wire body the lead reinforced insulation is set, and remainder is provided with the common insulation of lead.
According to result of calculation, by result of calculation required thickness is made in the insulation of the conductor turns in the different length scope respectively when turn insulation is wrapped up in the lead production process, guarantee the required insulation property of winding.
