For those of ordinary skill in the art, concrete meaning of the above-mentioned term in the present invention can be understood as the case may be.
EMU is in actual moving process, and the transformer in AuCT may break down, due to transformer
Installation site in AuCT is more special so that the replacement process of current transformer is extremely complex, in the prior art, usually logical
Following steps are crossed to replace the transformer to break down：
Step 1 disassembles the AuCT babinet entirety where the transformer to break down, this mistake from car body
Journey needs 10 tons of lifting platform trucks to carry out bracketing to AuCT babinet, and AuCT babinet and all wiring of car body are torn open
After removing, lifting platform truck is reduced to certain altitude, AuCT babinet is slowly removed into underbody.
Step 2 after AuCT babinet is removed underbody, is carried out the AuCT babinet using special equipment
Overturning；After removing bottom plate, the transformer to break down is disassembled and removed with other devices in AuCT babinet
Four lifting bolts.
Step 3 does not have the situation of any connection in the transformer to break down and other devices in AuCT babinet
Under, the transformer to break down is hung out into the babinet with overhead traveling crane and is put in designated position.
Step 4 hangs in new transformer to the installation site in AuCT babinet with overhead traveling crane, and with lifting bolt
New transformer is fixed in AuCT babinet.
Step 5, all wiring for restoring transformer and other devices in AuCT babinet after replacing, install bottom
AuCT babinet is overturn and AuCT babinet is hung on lifting platform truck with overhead traveling crane, by AuCT by plate
Babinet moves to car body installation site, then restores all wiring of AuCT babinet and car body.
But above-mentioned replacing options of the prior art are related to many unnecessary disassembly and installation processes, replace transformation
Device it is inefficient.The present invention provides a kind of transformer and replaces device and method, can improve the replacement efficiency of transformer.
