· Drawing on the advantages of Meichange, the transformer heat sink is installed in open mode to realize completely natural ventilation and heat dissipation performance, saving a lot of power loss caused by forced ventilation, and eliminating the defects of unreliable fan performance and easy overtemperature trip caused by forced ventilation; It also realizes that the electric-carrying body is completely sealed in the box, which solves the dust problem;
· The oil level meter, gas relay, pressure release and other devices of the transformer are all installed in open type, which can directly observe the operation of the transformer; · The protection function is exactly the same as the protection function of Oudian;
· Because there is no transformer room, the floor area of the whole machine is reduced compared with the European transformer, and the inlet and outlet mode of the transformer transformer structure saves a lot of copper, so the cost of the whole machine is lower than the European transformer, and the user's investment is reduced.
