Transformer coil device body and on-load switch are placed in common fuel tank, and when divide-shut brake, on-load switch will produce arcing electric discharge phenomena,
Divide-shut brake often, can have an impact the quality of transformer oil.
3, there are potential risks for transformer：Coil device body and high pressure full range fuse are placed in same fuel tank by common box type
It is interior, apparent fracture cannot be looked at straight when transformer fault, and when high pressure full range fuse burns fuse or even bursts, it can be serious
Pollute transformer oil, and then pollute the coil device body in the same fuel tank, in addition caused by burning metal particle powder etc. it is whole
Platform transformer is burnt.
4, repair is inconvenient, and time-consuming：When failure, even if only fuse is burnt, transformer coil device body part is no different
Often, when repair, it is also desirable to whole transformer oil all be bled off and could be repaired, waste transformer oil, also waste repair
Time, working hour etc..
Invention content
In order to solve the above problem existing for existing product, the utility model patent provides a kind of separate-box type photovoltaic generation

Auxiliary fuel tank upper end is provided with auxiliary fuel tank oil level indicator, auxiliary fuel tank oil filler point, pressure gauge, pressure relief valve, and lower end is provided with auxiliary fuel tank
Oil discharging valve, main fuel tank upper end are provided with Main Tank Injection hole, main fuel tank oil level indicator, and lower end is provided with main fuel tank oil discharging valve,
The auxiliary fuel tank upper end is provided with temperature probe.
The characteristics of the utility model：
1, fuel tank of the common box type equipped with transformer coil device body and all kinds of protection components is made into two parts：It is named respectively
For main fuel tank and auxiliary fuel tank, transformer oil is divided into two parts by main fuel tank and auxiliary fuel tank by branch mailbox partition board, a portion,
In main fuel tank, as the dielectric of transformer coil device body, another part, in auxiliary fuel tank, as the exhausted of protection component
Edge medium, two parts transformer oil, and be not communicated with, so the case where there is no cross contaminations；Electric part passes through one point
Separator for container is separated, wherein trepanning on demarcation strip, installs high-voltage wall bushing, for connecting the component between two fuel tanks,
Reach electrical communication.
2, transformer coil device body in main fuel tank is housed, low-voltage lead is drawn by the low-pressure side of coil device body, is connected to
Low-tension bushing completes the coupling part of low-voltage line.High-voltage tap lead and high pressure phase line are drawn in high-pressure side, and wherein high-voltage connection connects
It is connected to tap switch, high pressure phase line is connected to the electrical connection of waiting auxiliary fuel tank after high-voltage wall bushing.
3, include in auxiliary fuel tank, high-voltage wall bushing, on-load switch, high pressure full range fuse, bushing and its
He protects component.The high pressure phase line taken over by high-voltage wall bushing by main fuel tank is first connected to on-load switch, then connects again
To high pressure full range fuse, it is finally connected to bushing, completes the coupling part of high-voltage line.
It thereby realizes, main fuel tank and the cooling medium, that is, transformer oil of auxiliary fuel tank insulation separate, while by transformer
Coil device body and all kinds of protection components separate.Transformer breaks down, if the core component coil device body of transformer, does not have
There is exception, only between on high-tension side wall bushing and combination switch, between on-load switch and high pressure full range fuse, fusing
High pressure phase line between device and bushing burn or above-mentioned auxiliary fuel tank in component burn extremely, auxiliary fuel tank at this time
Interior transformer oil can be contaminated, and the transformer oil in main fuel tank will not be affected, and be avoided because of transformer oil
Pollution, metal powder granulates when also avoiding burning enter transformer coil and stand up that short circuit, whole transformer is caused to burn
The case where.
4, in repair, if the component in auxiliary fuel tank is burnt, and is needed replacing, the total case transformer of tradition
Depot repair is needed, the transformer oil in whole fuel tank is all removed, it, be to this transformer while replacing component
Coil device body, is rinsed with transformer oil, or to be done kerosene oil-gas and mutually be dried, and ensures the cleaning of coil device body part, and this new
Type separate-box type combined type transformer for photovoltaic generation, it is only necessary to replace the damage component in auxiliary fuel tank, shorten repair
Period.
The beneficial effects of the utility model are：On the basis of ensureing traditional transformer function, it is effectively guaranteed main oil
Transformer part, transformer oil in case and auxiliary fuel tank will not be influenced each other, mutually be polluted；The failure rate of transformer is reduced,
