Abstract
The invention provides a photovoltaic power generation inversion and boosting smart box-type transformer substation which comprises a box-type transformer substation transformer. The box-type transformer substation transformer comprises a transformer body, a high-voltage bushing and a low-voltage bushing. The high-voltage bushing is installed on one side edge of the transformer body. The low-voltage bushing is installed on the other side edge of the transformer body. The front edge and the rear edge of the transformer body are each provided with radiating fins. The photovoltaic power generation inversion and boosting smart box-type transformer substation further comprises a high-voltage chamber and a low-voltage chamber. A high-voltage cabinet is installed inside the high-voltage chamber. The high-voltage bushing is connected with the high-voltage cabinet. A low-voltage cabinet is installed inside the low-voltage chamber. An alternating-current low-voltage cabinet is installed inside the low-voltage cabinet. The low-voltage bushing is connected with the alternating-current low-voltage cabinet. Inverters are arranged inside the low-voltage chamber. By the adoption of the photovoltaic power generation inversion and boosting smart box-type transformer substation, a traditional line outgoing mode is changed, no voltage transformation chamber is needed, the radiating effect is good, and the low-voltage cabinet is reasonably designed, so that the box-type transformer substation meets the requirements for the two power transmission processes of inversion and boosting at the same time, and is high in practicability.
Description
Technical field
The present invention relates to a kind of photovoltaic inversion boosting intelligent box to become.
Background technology
Box-type substation (case change) is a kind of by high voltage switchgear, distribution transformer and low-voltage distribution equipment, lines up indoor, the outdoor close-coupled controller switching equipment be integrally prefabricated in the factory by certain connection plan.Organically combine by functions such as high powered, transformer pressure-reducing, low-voltage distributions, be arranged in a protection against the tide, antirust, dust-proof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, moveable steel construction casing, electromechanical integration, totally-enclosed operation, be specially adapted to urban network construction and upgradation, a kind of brand-new transformer station emerged after Shi Ji civil engineering transformer station.Box-type substation is applicable to mine, factory and enterprise, oil gas field, wind power photovoltaic power station, urban and rural housing community, city public transformer, bustling downtown area and construction power supply etc.It instead of original civil engineering power distribution room and power distribution station, becomes novel complete change power distribution equipment.
Box-type substation is since appearance, and development is very rapid, and accounted for 70% of distribution transformer at countries in Europe, the U.S. accounts for 90%.The advantage of American Unit Substation is that floor space is little, is convenient to install and can go deep into load center, low cost, and shortcoming is that power supply reliability is low, and defencive function is few; The advantage that European-type box becomes is that power supply reliability is high, and defencive function is complete, and shortcoming is that the large floor space of volume is large, and cost is high, and hyperbaric chamber, low-pressure chamber and transformer room are relatively closed, and the heat radiation of transformer is more difficult.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of without the need to using transformation room, and radiating effect is good, and can meet the photovoltaic inversion boosting intelligent box change of inversion, boosting two kinds of needs simultaneously.
The invention provides a kind of photovoltaic inversion boosting intelligent box to become, comprise case and become transformer, described case becomes transformer and comprises transformer body, bushing and low-tension bushing, described bushing is installed on a side of described transformer body, described low-tension bushing is installed on another side of described transformer body, is all provided with fin in the front of described transformer body and back; Also comprise hyperbaric chamber and low-pressure chamber, be provided with high-voltage board in described hyperbaric chamber, described bushing is connected with described high-voltage board; Be provided with low-voltage cabinet in described low-pressure chamber, be provided with AC low-tension cabinet in described low-voltage cabinet, described low-tension bushing is connected with described AC low-tension cabinet, in described low-pressure chamber, be also provided with inverter.
Further, described inverter is two and is symmetricly set in the forward and backward side of described low-voltage cabinet.
Further, be provided with interchange entrance hole at a side of each described inverter, be provided with direct current entrance hole at another side of each described inverter, two described interchange entrance holes are positioned at the dual-side of described AC low-tension cabinet.
Photovoltaic inversion provided by the invention boosting intelligent box is adopted to become, change traditional line mode, because adopt bushing to be installed on a side of transformer body, low-tension bushing is installed on another side of transformer body, transformer body and fin are completely in atmosphere exposed, thus reach without the need to using transformation room, the technique effect that radiating effect is good; Because adopt, low-pressure chamber is reasonably designed again, adopt and be provided with inverter in low-pressure chamber, make box-type substation can meet the needs of inversion, boosting two kinds transmission of electricity process simultaneously, practical, be applicable to large-scale promotion and use.
