Abstract

The utility model discloses a kind of compact 10kV combined type transformer for photovoltaic generation, including transformer, hyperbaric chamber, low-pressure chamber, it is characterised in that: the generally structure of falling triangle disposition, hyperbaric chamber is in left side, and for transformer on right side, front side is low-pressure chamber.Novel 10kV photovoltaic is changed to the structure of falling triangle disposition with Combined transformer structure, and hyperbaric chamber is in left side, and transformer is in right side, all low-pressure chambers in front side.The utility model make low-pressure chamber space increase, low-voltage electrical element can reasonable Arrangement, facilitate operation and maintenance, furthermore new structure overall volume reduces 20%;The arrangement of new construction, is conducive to the reduction of cost, and inner space can satisfy the demand of different user, new structure has the advantages such as volume is smaller, price is lower, structure arrangement is clear simultaneously, maintenance facilitates using upper more compact, reasonable.

Description

Compact 10kV combined type transformer for photovoltaic generation
Technical field
The utility model relates to a kind of compact 10kV combined type transformer for photovoltaic generation, are suitable for new energy photovoltaic and send out Electrical domain.
Background technique
In recent years, country was increasing to the project support dynamics of new energy, and the Sheng of roof photovoltaic rises, the liter of high pressure 10kV Pressure station demand is more and more, and conventional boost case becomes mainly based on the 35kV of high-pressure side, with prevailing, the high-pressure side of roof photovoltaic The case change demand of 10kV is increasing, and the combined type transformer for photovoltaic generation structure of 10kV is typically all 35kV's at present On the basis of develop, high and low pressure chamber, transformer are become in left side, transformer in centre with triangle disposition structure arrangement, hyperbaric chamber It is low-pressure chamber on front side of depressor, is fuse room on the right side of transformer.This arrangement volume is larger, and cabinet space arrangement does not conform to Reason, hyperbaric chamber wasting space, low-pressure side insufficient space cause current low-pressure chamber electrical component arrangement unreasonable, and finishing operations are not It is convenient.
Summary of the invention
The utility model patent provides a kind of compact 10kV combined type transformer for photovoltaic generation, the skill taken Art scheme are as follows:
A kind of compact 10kV combined type transformer for photovoltaic generation, including transformer, hyperbaric chamber, low-pressure chamber, feature Be: the generally structure of falling triangle disposition, hyperbaric chamber is in left side, and for transformer on right side, front side is low-pressure chamber, is equipped in hyperbaric chamber Sensor and arrester, transformer are provided with bushing, on-load switch, low-tension bushing and high-tension fuse, set in low-pressure chamber There are the dry change of low-voltage cabinet, auxiliary, UPS, hyperbaric chamber is assembled using cold-rolled steel sheet, and transformer case uses the opening plate of 4mm thickness It is welded, hyperbaric chamber and transformer case stitching portion rely on bolt fastening, and bushing is installed in stitching portion aperture placed in the middle, described Bushing a part be immersed in transformer oil, another part is exposed in air, plate is welded and fixed at the top of bushing, Arrester is mounted in the fixed plate of welding;On-load switch, low-tension bushing and high-voltage fuse are installed on transformer case fuel tank Disconnected device, on-load switch, low-tension bushing and high-tension fuse are serially connected by the copper lead of 16mm2, are placed in low-pressure chamber Low-voltage cabinet, auxiliary do tri- change, UPS band electric parts, pass through conducting wire connection between the dry change of low-voltage cabinet, auxiliary, UPS.
The utility model further includes power supply base channel steel, is used between the power supply base channel steel and combined transformer It is bolted.
The beneficial effects of the utility model are:
1, the utility model arrangement is changed to the structure of falling triangle disposition, and hyperbaric chamber is arranged in left side, and transformer arrangement exists Right side, low-pressure chamber are arranged in front side.Cabinet overall volume compared to conventional boxes become reduce 20%, sufficiently borrow transformer high-low-voltage every Plate does wallboard, reduces the dosage of steel plate, saves cost.High and low pressure chamber, transformer arrangement mode are more clear, are compact.
2, the utility model hyperbaric chamber reduced space, low-pressure chamber space increase, and electrical component arranges more adduction in low-pressure chamber Reason, facilitates installation, operation, maintenance.And sufficient extending space has been reserved, a variety of electrical components can be installed in low-pressure chamber additional.
3, it is connected by screw bolts between the utility model pedestal channel steel and combined transformer, it is not only easy to disassemble, but also Transformer need to be only hung when lifting can be realized the integral hoisting of case change, eliminate special hanger, convenient and practical.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure of the utility model.
Fig. 2 is the utility model partial structural diagram.
Specific embodiment
A kind of compact 10kV combined type transformer for photovoltaic generation, including transformer 11, hyperbaric chamber 1, low-pressure chamber 7, Be characterized in that: the generally structure of falling triangle disposition, hyperbaric chamber 1 is in left side, and for transformer 11 on right side, front side is low-pressure chamber 7, high pressure Sensor 2 and arrester 5 are equipped in room 1, transformer 11 is provided with bushing 6, on-load switch 8, low-tension bushing 9 and high-voltage fuse Break device 10, and the dry change of low-voltage cabinet, auxiliary, UPS are equipped in low-pressure chamber 7, high pressing sleeve is equipped between the hyperbaric chamber 7 and transformer 11 The top of bushing 6 is arranged again in pipe 6, the arrester 5, is electricity between the on-load switch 8 and high-tension fuse 10 Property connection.
The utility model case is become pedestal and is welded using channel steel, and spiral shell is used between the pedestal and combined transformer It tethers and connects.
1, the utility model arrangement is changed to the structure of falling triangle disposition, and hyperbaric chamber is arranged in left side, and transformer arrangement exists Right side, low-pressure chamber are arranged in front side.Cabinet overall volume compared to conventional boxes become reduce 20%, sufficiently borrow transformer high-low-voltage every Plate does wallboard, reduces the dosage of steel plate, saves cost.High and low pressure chamber, transformer arrangement mode are more clear, are compact.
2, the utility model hyperbaric chamber reduced space, low-pressure chamber space increase, and electrical component arranges more adduction in low-pressure chamber Reason, facilitates installation, operation, maintenance.And sufficient extending space has been reserved, a variety of electrical components can be installed in low-pressure chamber additional.
3, it is connected by screw bolts between the utility model pedestal channel steel and combined transformer, it is not only easy to disassemble, but also Transformer need to be only hung when lifting can be realized the integral hoisting of case change, eliminate special hanger, convenient and practical.
