The invention provides a transformer replacing device and method. The device comprises a supporting frame, a bearing tray and a bearing tray movable platform, wherein the supporting frame comprises aframe body, a first cross beam and a second cross beam, the first cross beam and the second cross beam are horizontally fixed at the top end of the frame body in parallel, and groove holes are formedin the two ends of the first cross beam and the two ends of the second cross beam; the positions of the groove holes correspond to the positions of transformer hoisting bolt holes; the bearing tray comprises a tray body and bearing balls, and the bearing balls are arranged on the surface of the tray body; the bearing tray is placed on the bearing tray movable platform, and the supporting frame isplaced on the bearing tray; and the supporting frame moves on the bearing tray movable platform through rolling of the bearing balls. According to the transformer replacing device, independent disassembling or installing of a transformer can be carried out on an auxiliary converter box body by a user, so that unnecessary disassembly and installation processes are omitted, and replacement efficiency of the transformer is improved.
Description
Technical field [0001] The invention relates to mechanical manufacturing technology, in particular to a transformer replacement device and method. Background technique [0002] The auxiliary converter is one of the important components of the high-speed EMU. The auxiliary converter includes the main controller, coupling circuit breaker, filter choke, pulse width modulation inverter and transformer, etc. The auxiliary converter is used for the auxiliary The input power and output power of the converter are isolated. In the actual operation process, the transformer will inevitably fail, and efficient replacement of the faulty transformer is currently an urgent problem. [0003] In the prior art, when disassembling a faulty transformer, the auxiliary converter box is usually removed as a whole, and then the faulty transformer is removed from the auxiliary converter box; the new transformer is installed At the same time, first install the new transformer in the box of the auxiliary co...
