Abstract
The invented method and equipment is used to convert three phases power supply into single-phase power supply. The combined V/I connection mode is adopted in the transformer that utilizes both features of V type and I type connection mode. The three phases power supply is converted into single-phase power supply directly, it has changed unbalanced status effectively. The iron core structure is three phases core type. There is not any winding surrounding the middle column. One high voltage winding and two low voltage winding with equal number of turns are placed on each side column. A corrugation oil tank used in this invention provides good thermal diffusivity.
Description
One, technical field
The present invention relates to a kind of method of power conversion and the device that method constituted thus, be mainly used in three phase mains is converted to single phase poaer supply.
Two, background technology
Because the power supply formula of China all adopts the three-phase and four-line supply power mode, when the user needs single phase poaer supply, then take up an official post and get one and constitute single phase poaer supply mutually, and this supply power mode needs single phase poaer supply the user from three phase mains, and when load is big, very easily cause the unbalanced phenomenon of three phase mains.The trip phenomenon of present transformer station nearly all is because central a certain the overload operation of three phase mains causes.In addition, during domestic employing Y/ delta connection mode transformer single phasing, the capacity utilance has only 66.7%, and the loss of transformer itself is big, and this is a very big waste for electric energy, therefore necessary the improvement.
Three, summary of the invention
The objective of the invention is to, at the deficiency of existing transformer, propose a kind of method and device of novel changing three-phase transformer to single-phase one, this kind transformer directly is converted to single phase poaer supply by three phase mains, and it is good to have balance, the characteristics that the capacity utilance is high.
The objective of the invention is to be achieved by following technical proposals, the V/I connected mode of V-arrangement and the combination of the I shape mode of connection is adopted in the wiring of transformer, and directly directly be converted to single phase poaer supply by three phase mains, its core structure is the three-phase core type, center pillar is any coil of suit not, and two side columns are respectively placed the low pressure winding of a high pressure winding and two sections equal turn numbers, simultaneously for solving the problem of heat radiation, the present invention has adopted corrugated tank, has good thermal diffusivity.The present invention utilizes the characteristics of the mode of connection of V-arrangement and I shape, and its applied in any combination in transformer, directly is converted to single phase poaer supply with three phase mains, has changed the unbalanced situation of three phase mains effectively, has also improved the capacity utilance of transformer simultaneously.Make 66.7% capacity utilance of former Y/ △ type transformer bring up to existing 86.6% capacity utilance.Can satisfy bigger equipment of single-phase load and user's power demands preferably, be a kind of desirable single-phase converting equipment, and employing is worthy to be popularized.

Five, specific embodiments
The invention will be further described below in conjunction with accompanying drawing. The present invention utilizes V-arrangement and I The characteristic of the mode of connection of shape, with V-arrangement and I shape mode of connection applied in any combination in transformer The high-low pressure winding consists of the V/I connected mode. From accompanying drawing, can find out, the present invention includes shell Body 1, radiator 2, fuel tank 3 and transformer core more than 4 parts is characterized in that transformer core 4 iron core 5 is three-phase core formula, and its center pillar 6 is not set with any coil, and two side columns 7,8 are respectively put Put the low- voltage coil 11,12 of a high pressure winding 9,10 and two sections equal turn numbers. The while transformation The radiator 2 of device is corrugated radiator, and is combined into corrugated tank with transformer case 1. And the wiring connected mode of the high-low pressure winding of transformer core is V/I type connected mode.
