(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes that transformer body 1, transformer body 1 are arranged
In transformer body fuel tank 2, outside transformer body fuel tank 2, it is connected with loaded tap switch oil case 3.Transformer body oil
The first binding post 4, the first binding post 4 side and transformer body fuel tank it is provided with between case 2 and loaded tap switch oil case 3
The second binding post 5 in 2 is connected, the first binding post 4 opposite side and the 3rd terminals in loaded tap switch oil case 3
Son 6 is connected, and the 3rd binding post 6 is connected with the 4th binding post 7, the 4th binding post 7 and loaded tap switch oil case 3
Interior load ratio bridging switch is determined contact 8 and is connected.First binding post 4 is connected by the first securing member 9 with the second binding post 5
Connecing, the 3rd binding post 6 is connected with the first binding post 4 in inserting First Line connecting terminal 4, the 4th binding post 7 with have load
Tap switch fixed contact 8 is connected by the second securing member 10.3rd binding post 6 and the 4th binding post 7 are connected to paper bag
On copper stranded conductor 11, the second binding post 5 is connected with the tap lead in transformer body 1 by paper bag copper stranded conductor 11.First
Binding post 4 is cast in resin panel 12, and resin panel 12 is placed in transformer body fuel tank 2 and loaded tap switch oil case 3
Between.Transformer body fuel tank 2 is connected by the 3rd securing member 13 with loaded tap switch oil case 3.
Use a kind of ULTC Oiltank structure of the present invention, the switching of load ratio bridging switch is switched and oil
Room, tap selector etc. are separately positioned in loaded tap switch oil case 3, and transformer body is separately positioned at transformer body oil
In case 2, loaded tap switch oil case 3 is linked together by the 3rd securing member 13 with transformer body fuel tank 2.Transformer body
Tap lead in 1 is connect by first in the resin panel 12 between loaded tap switch oil case 3 and transformer body fuel tank 2
Line terminals 4 determines with load ratio bridging switch that contact 8 is corresponding to link together, and lead-in wire wherein used is paper bag copper stranded conductor 11.First
Binding post 4 casts directly in resin panel 12；The first binding post 4 in transformer body fuel tank 2 side is by first
Securing member 9 is corresponding with the second binding post 5 being welded on paper bag copper stranded conductor 11 to link together；At loaded tap switch oil case
First binding post 4 of 3 sides is to connect with the 3rd binding post 6 being soldered on paper bag copper stranded conductor 11 by the way of plug connects
It is connected together；Contact 8 determined by load ratio bridging switch and the 4th binding post 7 being crimped on paper bag copper stranded conductor 11 uses the second fastening
Part 10 links together.
Use a kind of ULTC Oiltank structure of the present invention, due to transformer body fuel tank 2 and loaded tap-off
There is no the contact of oil between switch tank 3, if so transformer body 1 breaks down, only transformer body 1 need to be put
Oil, suspended core and process etc.；If load ratio bridging switch breaks down, only loaded tap switch oil case 3 need to be drained the oil, check and
Maintenance etc.；Greatly reduce maintenance load.If running scene, load ratio bridging switch generation catastrophe failure and nothing at transformator
Method continues to run with, it is also possible to load ratio bridging switch is hung out maintenance, even returns factory's maintenance.Now, only operation tap will need to be in
, and be connected to load ratio bridging switch and determine the tap lead of contact 8 and be directly grounded, the tap lead of remaining non-operating state is dismantled i.e.
Can.The transformator of this kind of state is equivalent to off circuit tap changing transfor mer, but may insure that transformator recovers in the short period of time
Properly functioning, loss of outage is down to minimum, has won time enough for on-load tap switch maintenance or replacing simultaneously.
