Description

Container-type photovoltaic transformer oil conservater

Technical field

The utility model relates to photovoltaic transformer oil storages in a kind of container.

Background technique

Photovoltaic power generation is the power generation process using Volta effect principle, and power generation process only has the conversion of optical-electronic, do not occur The conversion of other energy, therefore have the characteristics that efficient, environmental protection.In the present that global environmental pollution and energy crisis are got worse It, photovoltaic power generation has become the important force of generation of electricity by new energy industry.

Photovoltaic power generation New Energy Industry is fast-developing, and major Utilities Electric Co.'s photovoltaic power generation scale constantly expands, mating Photovoltaic power generation transformer demand expand therewith.

But widely applied photovoltaic power generation transformer largely all has the disadvantage in that currently on the market

1. conventional Europe, which becomes oil conservater, does not have capsule, transformer oil is contacted with air for a long time to be easy to aoxidize；Conventional oil storage Cabinet is connected in transformer top by cabinet feet, and occupied space is excessive, is unfavorable for being placed in inside twenty equivalent unit；It is conventional Oil conservater uses cylindrical structure, and one timing swelling volume of height is small, leads to oil conservater easily oil spout.

2. conventional beauty, which becomes, can not detect the methane gas that transformer is generated by abnormal operation；Because conventional beauty becomes in transformer Top is gas, and part QJ2-40 type gas relay is placed in transformer top, can only pass through the extraction catheter in the middle part of fuel tank Collect methane gas, the methane gas of generation is gathered on fuel tank top, therefore gas relay cannot accurately detect light watt This, QJ12-40 type gas relay does not have the function of detection grave gas.

Summary of the invention

In order to solve the above problem existing for existing products in markets, the utility model patent provides light in a kind of container Volt transformer oil storage, it is reasonable in design, and it is provided with the generation that light and heavy gas can be effectively detected in gas relay, pacify Full performance is high, occupies little space.

For achieving the above object, technical solution adopted in the utility model are as follows:

A kind of container-type photovoltaic transformer oil conservater is arranged right above fuel tank, it is no longer arranged between fuel tank Cabinet feet, it includes oil conservater, and oil conservater is polygon columnar structures, uses capsule inner cavity, lower end and fuel tank upper box lid in oil conservater It being fixedly connected, oil conservater lower part is connect by union with fuel tank, toward stringing out of shape on the outside of fuel tank after union connection fuel tank upper box lid, Case lid outer is stretched out, is mounted on the outside of oil tank of transformer upper box lid by butterfly valve, bellows, gas relay, is arranged in union There are gas relay, butterfly valve；The union horizontal direction arrangement, gradient are less than or equal to 3 °.

Draw dehydrating breather in the oil conservater upper end；Oil conservator oil level indicator is placed in oil conservater short-axis direction, convenient for direct Read the accurate calibration of oil level.

The oil conservater lower part side is provided with Oil-filling and drainage valve door.

The union depression angle direction, is in " Kan " shape, and gas relay, butterfly valve are arranged at the outer of fuel tank upper box lid Along outside, as shown in Figure 2.

The gas relay is QJ13-50 or QJ13-80 type, and butterfly valve is DN50 butterfly valve, is mounted on gas relay Both ends；The dehydrating breather is 1kg silica gel filter.

The utility model has the following beneficial effects: with conventional photovoltaic transformer ratio compared with the oil conservater uses four side columns Type, oil conservater and case lid integrally connected, can greatly promote the volume of oil conservater in one timing of height dimension, ensure that transformer The expansion space of oil, while reduction transformer overall dimensions are reduced, practicability enhancing；Oil conservater uses capsule oil conservator, makes Transformer oil completely cuts off completely with air, prevents transformer oil ageing, effectively extends the service life of transformer；Gas relay It is arranged in and is sidled in the union of arrangement horizontally outward, reduces transformer outer dimension；Fuel tank generates a small amount of device in Gas simultaneously It can be collected into gas relay when body, when transformer generates bulk gas suddenly causes oily speed too fast, gas relay Device can accurately detect fuel-displaced speed variation, provide grave gas trip signal, and security performance is high.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is Fig. 1 overlooking structure diagram.

1. oil conservater, 2. upper box lids, 3. unions, 4. gas relays, 5. oil level indicators, 6. dehydrating breathers, 7. butterfly valves.

Specific embodiment

A kind of container-type photovoltaic transformer oil conservater as shown in drawings is arranged right above fuel tank, it and fuel tank Between cabinet feet is no longer set, it includes oil conservater 1, and oil conservater 1 is polygon columnar structures, use capsule inner cavity in oil conservater 1, under End is fixedly connected with fuel tank upper box lid 2, and 1 lower part of oil conservater is connect by union 3 with fuel tank, after union 3 connects fuel tank upper box lid 2 Stringing out of shape on the outside of toward fuel tank stretches out case lid outer, is mounted on oil tank of transformer by butterfly valve 7, bellows, gas relay 4 On the outside of upper box lid, gas relay 4, butterfly valve 7 are provided in union 3；3 horizontal direction of the union arrangement, gradient are less than Equal to 3 °.

Draw dehydrating breather 6 in 1 upper end of oil conservater；Oil conservator oil level indicator 5 is placed in oil conservater short-axis direction, convenient for straight Connect the accurate calibration for reading oil level.

The 1 lower part side of oil conservater is provided with Oil-filling and drainage valve door.

The 3 depression angle direction of union is in " Kan " shape, and gas relay, butterfly valve 7 are arranged at fuel tank upper box lid 2 Outer on the outside of, as shown in Figure 2.

The gas relay 4 is QJ13-50 or QJ13-80 type, and butterfly valve 7 is DN50 butterfly valve, is mounted on gas relay 4 both ends of device；The dehydrating breather 6 is 1kg silica gel filter.

Four side column types, oil conservater and case lid integrally connected are used compared with, the oil conservater with conventional photovoltaic transformer ratio, The volume of oil conservater can be greatly promoted in one timing of height dimension, the expansion space of transformer oil is ensure that, reduces simultaneously Reduce transformer overall dimensions, practicability enhancing；Oil conservater uses capsule oil conservator, completely cuts off transformer oil completely with air, prevents Only transformer oil ageing effectively extends the service life of transformer；Gas relay setting is being sidled horizontally outward to cloth In the union set, transformer outer dimension is reduced；Simultaneously fuel tank generate a small amount of methane gas when can be collected into gas after In electric appliance, when transformer generates bulk gas suddenly causes oily speed too fast, gas relay can accurately detect fuel-displaced speed and become Change, provide grave gas trip signal, security performance is high.

The above is only the preferred embodiment of the utility model, it is noted that for the ordinary skill of technical field For personnel, without departing from the principle of this utility model, several improvement can also be made, wound is not being paid in these improvement It also should be regarded as the protection scope of the utility model under the premise of the property made labour.
