The L-type copper coin of case lid copper shield connection, it is to avoid fuel tank and case are along hot-spot.
Described folder magnetic shield is right against main empty path, and covers the folder web region in addition to drawstring seat, and wherein one
Bar side laminating folder web, another side laminating core-lamination stack.
Insulating part is provided between described folder magnetic shield and folder web, it is ensured that both are reliable to insulate.
Described folder magnetic shield is fixed on folder web by securing member, and magnetic shield thickness can be leaked according to device body end
The close selection of magnetic magnetic.
Described folder magnetic shield end is provided with round copper rod, it is to avoid shielding end wedge angle generation office puts.
Described bar shaped magnetic shield is fixed by the briquetting of upper and lower make-up, and briquetting is provided with notch, bar shaped magnetic shield card
It is connected in notch.
Described fuel tank shielding construction is fixed by the bent plate being arranged on fuel tank tank wall, including being arranged on inner wall of oil tank
Copper shield and be arranged at the magnetic shield on copper shield surface, the magnetic shield is connected with folder web by independent lead-out wire.
Described magnetic shield passes through paper groove from inside to outside and cardboard is wrapped up, and by without latitude glass tape colligation, it is ensured that can
By insulation.
Elastic glue stick is provided between described L-type copper coin, is ensured that two L-type copper coin contacts are good using glue stick elasticity, is kept away
Exempt from transformator connecting bolt and case is saved up and down along because the generation of leakage field concentration of local is overheated.
Described folder magnetic shield and bar shaped magnetic shield are connected with folder web by independent lead-out wire respectively, it is ensured that reliable
Ground connection.
The utility model proposes a kind of stray transformer flux controls shielding construction, leakage field can be controlled to greatest extent, reduce
Loss, it is to avoid hot-spot, it is ensured that transformer safety is run.
