Description
Technical field
The present invention relates to a kind of branch mailbox combined transformers.
Background technique
High-tension fuse, high voltage load switch and transformer body are usually placed on together by existing case combined transformer altogether
In one fuel tank, because high-tension fuse is easier the impact and short-circuit conditions that happen suddenly, dimension during practical application is run
When repairing replacement, transformer oil whole in fuel tank need to be frequently replaced, maintenance cost is larger.
Summary of the invention
The purpose of the present invention is to provide a kind of branch mailbox combined transformers, are total to case combined type in the prior art for solving
The larger problem of transformer maintenance cost.
To achieve the above object, the technical solution of branch mailbox combined transformer of the present invention is:Branch mailbox combined transformer packet
Include main fuel tank, high-tension fuse, high voltage load switch and transformer body, the transformer body and the high voltage load switch
In the main fuel tank, which further includes and the main fuel tank mutually disconnected secondary fuel tank, and this time
Fuel tank is located at outside the main fuel tank, and the high-tension fuse is fixed in the secondary fuel tank by fixing support component, and passes through height
Pressure fuse lead is connect with the high voltage load switch.
The beneficial effects of the invention are as follows：This main fuel tank is not connected to mutually with time fuel tank, and the high-tension fuse is located at institute
The branch mailbox combined transformer for stating time fuel tank, when the high-tension fuse pollutes oil liquid, catastrophic failure or short circuit, Ke Yidan
The oil liquid in time fuel tank is solely discharged, high-tension fuse is replaced or is repaired, while facilitating maintenance, reduces maintenance cost.
Above-mentioned secondary fuel tank and the main fuel tank can be by spaced aparts, this scheme can reduce the material of time fuel tank and main fuel tank
Expect cost.
The height of above-mentioned secondary fuel tank is lower than the height of the main fuel tank, and this set makes the sealing in main fuel tank and time fuel tank
Sealing structure is bad and when lead to the oil liquid permeability in main fuel tank and time fuel tank, since the oil liquid pressure in main fuel tank is not small
Oil liquid pressure in secondary fuel tank so that contaminated oil liquid in time fuel tank be prevented to enter main fuel tank, and then pollutes main fuel tank
Interior oil liquid.
The side wall of above-mentioned secondary fuel tank is connect with the side wall of the main fuel tank by sealed connecting component, this secondary fuel tank directly with
The mode of main fuel tank connection, reduces the volume of entire transformer, device structure is compact, space occupied is small.
Above-mentioned high-tension fuse lead is connect by wall bushing with the high voltage load switch, the line side of this scheme
Formula makes have better seal effect between the partition or side wall among high-tension fuse lead and main fuel tank and secondary fuel tank.
Above-mentioned fixed support component includes the fixed standing screw for supporting the high-tension fuse, and the standing screw is fixed
On the secondary fuel tank, and the insulating supporting board ends are supported by the branch iron being fixed on the secondary fuel tank, this support high pressure
The mode of fuse keeps the position of the high-tension fuse more firm.
Above-mentioned sealed connecting component includes rectangular flange, rectangular seal pad and sealed insulation plate, the secondary fuel tank fastener
Across the rectangular flange, the rectangular seal pad and the sealed insulation plate, and it is connect with the side wall of the main fuel tank, it is this
In such a way that rectangular seal pad and sealed insulation plate are connect with the rectangular flange by fastener, make main fuel tank and time fuel tank
Between reach good sealing effect, keep the structure for the secondary fuel tank being mounted on main fuel tank side wall more firm.

Fig. 2 is branch mailbox Combined transformer structure left view of the present invention；
Fig. 3 is branch mailbox Combined transformer structure top view of the present invention.
Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment of branch mailbox combined transformer of the invention, as shown in Figure 1 to Figure 3, the branch mailbox combined type variable-pressure
Device includes main fuel tank 2.1 and time fuel tank 1.1, is equipped with high voltage load switch 5 and transformer body 7, secondary fuel tank in main fuel tank 2.1
High-tension fuse 1.4 is equipped in 1.1, and the secondary fuel tank 1.1 is located at the side of main fuel tank 2.1, and passes through by screw or bolt
The sealed connecting component being made of rectangular seal pad 1.6, rectangular flange 2.2 and sealed insulation plate 2.3, the side wall with main fuel tank 2.1
Connection makes time fuel tank 1.1 and the isolation of main fuel tank 2.1, sealing, avoids the high-tension fuse 1.4 in time fuel tank 1.1 to main fuel tank
Oil liquid in 2.1 generates pollution.High-tension fuse 1.4 passes through the wall bushing 2.4 on sealed insulation plate 2.3 for high-tension fuse
Lead 4 is connected on the high voltage load switch 5 and transformer body 7 in main fuel tank 2.1.
The height of the secondary fuel tank 1.1 is lower than the height of main fuel tank 2.1, avoids sealing because of main fuel tank 2.1 and time fuel tank 1.1
It is bad and cause the oil liquid polluted in time fuel tank 1.1 by the free carbon that the folding of high-tension fuse 1.4 generates due to main fuel tank 2.1 with
Oil liquid pressure between secondary fuel tank 1.1 is poor and enters in main fuel tank 2.1, and then pollutes the oil liquid in main fuel tank 2.1, is also convenient for simultaneously
Operator replaces the maintenance of high-tension fuse 1.4 in secondary fuel tank 1.1.
Main fuel tank 2.1 is connected separately with gilled radiator 8 in the adjacent two sides without containing time fuel tank 1.1, in addition two sides point
It is not connected with low-tension bushing 6 and bushing 3, wherein bushing 3 is located at the top of time fuel tank 1.1.
The inner wall upper and lower side of secondary fuel tank 1.1 is respectively welded branch iron 1.2, the insulation support plate inside secondary fuel tank 1.1
1.3 connect with branch iron 1.2, together with the high-tension fuse standing screw 1.5 positioned at 1.1 front of time fuel tank, constitute fixed support
The high-tension fuse 1.4 is fixed, seals, limits its movement by the fixation support component of high-tension fuse 1.4.
It is additionally provided on secondary fuel tank 1.1 and pulls pressure relief valve 1.8, for secondary when being convenient for when oiling into secondary fuel tank 1.1
Air discharge in fuel tank 1.1；In the equipment course of work, high-tension fuse 1.4 can generate gas, at this time interruption maintenance, hand
Dynamic manipulator's pressure relief valve 1.8, convenient for the gas discharge inside secondary fuel tank 1.1.
As the embodiment of the present invention 2, it is with the difference of embodiment 1：Separate between the main fuel tank and secondary fuel tank
Arrangement is separated the main fuel tank and the secondary fuel tank by the partition of sealing, the branch mailbox combined transformer of this scheme,
Can solve the larger problem of transformer maintenance cost, and in the program transformer-cabinet materials it is less, cost is lower.
As the embodiment of the present invention 3, it is with the difference of embodiment 1：The securing supports are that other can consolidate
The structure for determining high-tension fuse position, its object is to limit movement of the high-tension fuse in secondary fuel tank.
As the embodiment of the present invention 4, it is with the difference of embodiment 1：The sealed connecting component be rectangle or other
