Product structure characteristics
High pressure coil: a multi-segment cylindrical structure, 630kVA and above are designed with cooling air duct, which is a non-filler glass fiber reinforced pouring system.
Low pressure coil: 400kVA and above with foil coil structure, resin end seal, surface is covered by high temperature curing of solid epoxy resin.
Iron core: using "step by step" lamination, laminated structure.
(4) is: by the steel plate stamping bending forming, compared with common clamp, increase tensile edge, ventilation slot structure, so as to make the core clamping compact, deformation, transformer ventilation performance is good wait for an advantage, has won the national patent (patent number ZL98215306.6).
The outer shell: it is composed of anti-corrosion aluminum, anti-corrosion, aluminum and aluminum alloy mesh, and has good ventilation and protective properties.
The wind cooling system: the fan adopts the low noise, large air volume, low loss of the amplitude flow fan.
All landowners temperature control temperature display device: temperature control temperature display device has cycle display three-phase winding hot spot temperature, shows three phase, and the maximum phase temperature automatic control of air cooling system start-stop and overtemperature alarm, computer networking, remote display and fault memory, and other functions.
