Structural Features
1.Protection System
Pt100 thermal resistors temperature control system is generally applied in the transformer body, pressure relief valve with contacts is equipped on the top of tank, oil indicator with contact and vacuum relays are equipped on the conservator, and as well, the oil pressure indicator with contacts is equipped in the tank. All this equipments can be applied for signal conversion and transfer. Both HV and LV bushings are pollution retardant porcelain oil type, which can lengthen the insulation space and be applied in high pollution condition. Padding plates and terminal case are made of stainless steel to make elegant appearance.
2. Tank
Wide-width steel plate is adopted to reduce welding seams on the flat roof, folded plate type tank, it has concise and dedicate appearance and also high mechanical strength which passed the standard positive pressure and vacuum test. In addition, special welding technology and groove type flange ensure the tank and the pipes are able of long time use without leakage. Wide plate radiation system equipped with heavy duty and low noise blowers rises up the heat dissipating center, improve the efficiency, reduce radiating plates and prevent leakage. It can be directly mounted on the transformer. And capsule type conservator can effectively delay the aging of the oil what is implanted in under vacuum condition to reinforce the electric strength.
