Abstract
The utility model relates to an interface transformer arrangement structure for a flexible direct current converter station. A closed interface transformer chamber is arranged in the converter station. The interface transformer arrangement structure comprises a transformer body and a radiator which is connected with the transformer body by an oil guide pipe, wherein the transformer body is arranged in the closed interface transformer chamber; and an open interface transformer chamber which is used for arranging the radiator is arranged in the converter station. By the interface transformer arrangement structure for the flexible direct current converter station, the transformer body with a low-frequency noise and the radiator without a mechanical noise are horizontally arranged in different spaces, namely the closed interface transformer chamber and the open interface transformer chamber in the converter station, in a split mode, so that a noise-reduction requirement of the converter station and a radiation requirement of the transformer are simultaneously met, and the operation failure of the converter station caused by poor radiation is further effectively avoided.
Description
Technical field
The utility model relates to a kind of interface transformer arrangement that is used for flexible DC converter station.
Background technology
Flexible DC power transmission (VSC-HVDC) technology is a kind of Novel DC technology of transmission of electricity based on voltage source converter (VSC), controlled shutoff device and pulse-width modulation (PWM) technology.Compare with traditional direct current transportation, have and control flexible, the raising stability of a system, increase the system dynamic reactive-load deposit, improve the quality of power supply, save technical advantage such as construction land, be applicable to that regenerative resource is incorporated into the power networks, many-sides such as isolated island power supply, asynchronous interconnected, urban distribution network power supply.
Flexible DC power transmission is as the important means that Future New Energy Source inserts and the down town powers, and the then corresponding construction of flexible DC converter station is in load center area, city, and this noise control and environmental suitability to current conversion station has proposed very high requirement.
Equipment in the current conversion station mainly contains interface transformer, converter valve, reactor etc., wherein, interface transformer itself has certain low-frequency vibration, secondly, because direct current transportation certainly will cause the part direct current to flow into the interface transformer primary side, cause that interface transformer iron core electromagnetism is saturated, and then interface transformer produces higher noise pollution inevitably, therefore, based on environmental requirement, integral type interface transformer of the prior art is placed in usually in the interior enclosure space of current conversion station and leaks to the influence of current conversion station neighboring buildings to reduce noise; Yet this has just caused the heat radiation of interface transformer bad, thereby causes the operation troubles of interface transformer easily, and then influences the operate as normal of current conversion station.
The utility model content
In order to solve the problem that above-mentioned prior art exists; the utility model aims to provide a kind of interface transformer arrangement that is used for flexible DC converter station; when satisfying the requirement of current conversion station noise reduction to be implemented in; improve the purpose of interface transformer self-radiating performance, thereby guarantee the operate as normal of current conversion station.
A kind of interface transformer arrangement that is used for flexible DC converter station described in the utility model, be provided with a closed interface transformer chamber in the described current conversion station, described interface transformer arrangement comprises a transformer body and a radiator that is connected with this transformer body by oil guide pipe, and it is indoor that described transformer body is arranged on described closed interface transformer, also is provided with an open type interface that is used to be provided with described radiator in the described current conversion station and becomes the radiator chamber.
At the above-mentioned interface transformer arrangement that is used for flexible DC converter station, described transformer body and radiator are horizontal separate form and are separately positioned on described closed interface transformer chamber and open type interface to become radiator indoor.
At the above-mentioned interface transformer arrangement that is used for flexible DC converter station, described transformer body comprises that one is provided with the fuel tank of flowline and oil inlet pipe, described radiator comprises a first line of a couplet pipe and a second line of a couplet pipe, and the flowline of described fuel tank is connected with the first line of a couplet pipe of described radiator by described oil guide pipe, and the oil inlet pipe of described fuel tank is connected with the second line of a couplet pipe of described radiator by described oil guide pipe.
Owing to adopted above-mentioned technical solution, transformer body and the radiator of no mechanical noise of the utility model by will having low-frequency noise is horizontal split and is arranged in different spaces, be closed interface transformer chamber and the open type interface change radiator chamber in the current conversion station, thereby satisfied the noise reduction requirement of current conversion station simultaneously, promptly reduced the influence of other equipment in the current conversion station and current conversion station neighboring buildings and satisfied the heat radiation requirement of transformer self, and then effectively avoided interface transformer because of the bad situation that causes the current conversion station job failure of dispelling the heat; Simultaneously, because radiator of the present utility model is arranged in the environment of open type, therefore can makes full use of natural draft and dispel the heat, thereby save the energy to a certain extent.
Description of drawings
Fig. 1 is a kind of schematic diagram that is used for the interface transformer arrangement of flexible DC converter station of the utility model.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, be provided with closed interface transformer chamber 4 and open type interface in the current conversion station in the utility model and become radiator chamber 5.
The utility model, it is a kind of interface transformer arrangement that is used for flexible DC converter station, comprise a transformer body 1 and a radiator 2, and transformer body 1 and radiator 2 are, and horizontal separate form is separately positioned on closed interface transformer chamber 4 and the open type interface becomes in the radiator chamber 5, wherein
Interface transformer arrangement of the present utility model adopts split-type structural, and transformer body 1 and radiator 2 are arranged in the rooms different in the current conversion station, being about to transformer body 1 is arranged in the independently closed interface transformer chamber 4, thereby can effectively shield its noise and vibration, in addition, because becoming the foundation of civil work structure of radiator chamber 5, closed interface transformer chamber 4 and open type interface is provided with into independent, break away from setting fully with other building foundations in the station, can guarantee like this when vibration takes place interface transformer, can not make interior other buildings in station vibration also take place and experience noise; Simultaneously, in the utility model natural cooling and the radiator 2 that do not have a mechanical noise are arranged in open-air open type interface and become in the radiator chamber 5, thereby improve radiating effect and its service behaviour of interface transformer greatly, and then guarantee the operate as normal of current conversion station.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
