Summary of the invention
In view of this, being necessary provides the coil manufacturing process of a kind of transformer inside easy, enhances productivity, and the high low-voltage coil wire winding of quality.
The present invention is achieved in that the low-voltage coil wire winding, mainly comprises the following steps:
Step 1: cleaning location;
Use clean towel that winding former is wiped clean, then on winding former, wrap one deck network for location, network for location uses glass fibre belt to fix;
Step 2: wound the line;
A, in accordance with regulations around to lift one's head the curved instrument of length ， Yong Wei Dao Xian Wei become to 90 °;
B, will wrap in the notch that lifting one's head of insulation be put into winding former, and start around the first circle, limit arranges along even circumferential the glass fibre belt that a plurality of thickness is 0.2mm around limit below wire turn;
When the second circle, glass fibre belt is turned over to wire turn, and at the second circle and between lifting one's head, the DMD that two layers of thickness is 0.2mm is set, and notch is downward;
When the 3rd circle, then glass fibre belt is turned over to wire turn and goes, then push down with other wire turn;
C, in the coiling process, the turn-to-turn space that wire transposition causes is used network for location to be filled and led up, all networks for location will be with the glass fibre belt colligation on adjacent wire turn, cut the knife-edge part DMD that to add every two layers of thickness be 0.2mm in transposition, when coil around when the ground floor final stage, a plurality of glass fibre belts are set and place along circumference below wire turn equably, and around complete final stage;
D, in the coiling process, the lead-out wire position needs reinforced insulation end to end, at 1kV(, does not comprise 1kV) and following electric pressure, start to wrap 2 layers of polyimide film two-fold half laps from root, with 2 layers of glass fibre belt half lap wrappings, wrapping length is higher than the rear coil end face 15mm of cast again;
Comprise 1kV at 1kV() and above, start to wrap at least 4 layers of polyimide film two-fold half laps from root, then, with at least 3 layers of glass fibre belt half lap wrappings, wrap up length higher than the rear coil end face 30mm of cast, first and last is lifted one's head to stagger and is drawn, and spacing is greater than 60mm;
E, coil rise layer place and need the DMD that 2 thickness of cushioning are 0.2mm, use glass fibre belt half lap one deck to carry out insulating wrapping, wrapping length 100mm, and the DMD that layer insulation is 0.2mm by thickness forms;
F, at coil around when the last circle, reserve length and cut off wire by the pattern requirement, carry out insulating wrapping;
G, after coil winds, bread one deck network for location outside, rare around fixing with glass fibre belt;
Step 3: the air channel rod is installed;
Just putting, straightening when the air channel rod is installed, and root is stuck in the winding former notch.
The advantage of low-voltage coil wire winding provided by the invention is: the present invention includes cleaning location, wound the line and three steps such as air channel rod installations, technological process is simple, easy to operate, enhance productivity, and the mass of coil of making is high.
