Power distribution and automation control for the power transformer cooling system are the major duties of the control cabinet. Internally, it could concentrate all power transformer measurement and signal terminals (including temperature controllers, oil flow relay, pressure relief valves, gas relay, bushing current transformer, oil level indication, whether all concentrated in the control cabinet is determined by the user, also could make another terminal box). Control cabinets can be categorised into floor-standing and wall-mounted types depending on how the transformer is installed on-site. The cabinet housing is built of high-quality steel (surface spray treatment) or high-grade stainless steel plate utilising a bent and welded structure. Users are allowed to select the type of control cabinet material based on their specific requirements, the climate at the installation site, the working environment, etc. The cabinet door is sealed with a professional sealing strip, and the vent window connects the interior to the outside air. It is water-proof, dust-proof, and has an IP54 protection class. Schneider, Siemens, ABB, and other imported or joint venture goods are chosen for cabinet components because of their low cost and dependable functioning.
