参照图1和图2,本发明的实施例,提供了一种新型干式变压器。1 and 2, an embodiment of the present invention provides a novel dry-type transformer.
新型干式变压器包括变压器器体300和壳体100。The novel dry-type transformer includes a
其中,变压器器体300包括线圈310和铁心320。壳体100设有纵向的通风道210,变压器器体300位于通风道210中,线圈310设有纵向的线圈风道330,壳体100设有进风口201和出风口202,进风口201和出风口202均与通风道210连通,进风口201位于变压器器体300的下方,出风口202位于变压器器体300的上方。The
需要说明的是,图2中的箭头为空气流的方向指示。It should be noted that the arrows in FIG. 2 indicate the direction of the air flow.
在该实施例中,将变压器器体300设置于纵向的通风道210中,进风口201设置在变压器器体300的下方,出风口202设置在变压器器体300的上方;当变压器器体300工作,产生热量,对周围空气加热;利用烟囱效应,使通风道210中的热空气往上升,在通风道210形成空气流,使冷空气从下方的进风口201进入通风道210中,并从上方的出风口202离开通风道210;另外空气流通过线圈310中的纵向的线圈风道330,能更好地带走线圈310产生的热量,快速对线圈310降温;烟囱效应形成的空气流将变压器器体300工作产生的热量带走,对变压器器体300降温散热,使变压器器体300能持续保持在正常的工作温度范围,提升了变压器散热能力;通过使线圈310的下部的工作温度比线圈310的上部的工作温度高,以增强烟囱效应,提升了变压器散热能力。In this embodiment, the
在变压器器体300工作的过程中,主要产热部分为线圈310部分,在线圈310中设置线圈风道330,能使通风道210中的空气流通过线圈310内部,将线圈310的热量快速带走;另外,线圈风道330的方向为纵向,与通风道210的方向相同,与空气流的流动方向相同,使得空气流能自然通过线圈风道330,不会受到阻拦而降低流速,顺利带走线圈310热量,有利于对线圈310降温散热。During the operation of the
需要说明的是,纵向并非限定与水平面成90度垂直,只要通风道210、线圈风道330的延伸方向为向上并存在垂直坡度,即使通风道210、线圈风道330的延伸方向与垂直线存在一定的倾斜角度,也属于纵向的范畴内。It should be noted that the longitudinal direction is not limited to be perpendicular to the horizontal plane at 90 degrees, as long as the extension direction of the
烟囱效应,属于热交换形式的一种表现;烟囱效应是指空气沿着有垂直坡度的空间向上升或下降,造成空气加强对流的现象。在有共享中庭、竖向通风风道、楼梯间等具有类似烟囱特征——即从底部到顶部具有通畅的流通空间的建筑物、构筑物中,空气靠密度差的作用,沿着通道很快进行扩散或排出建筑物的现象,即为烟囱效应。The chimney effect is a manifestation of the form of heat exchange; the chimney effect refers to the phenomenon that the air rises or falls along a space with a vertical slope, resulting in enhanced air convection. In buildings and structures with shared atriums, vertical ventilation ducts, stairwells, etc. with chimney-like features—that is, with unobstructed circulation space from the bottom to the top, the air moves quickly along the passage due to the difference in density. The phenomenon of diffusion or discharge from a building is known as the chimney effect.
烟囱效应为由热压而引起的自然通风。热压作用下的自然通风,由于物体内外空气的温度差产生了空气密度的差别,于是形成压力差,趋使室内外空气的流动。室内温度高的空气,因比重小而上升,并从物体上部风口排出,这时会在低密度空气原来的地方形成负压区,于是室外温度比较低而比重大的新鲜空气从建筑物的底部被吸入,室内外的空气源源不断的进行流动。The chimney effect is the natural ventilation caused by thermal pressure. In the natural ventilation under the action of hot pressure, the difference in air density is generated due to the temperature difference between the air inside and outside the object, so a pressure difference is formed, which tends to flow indoor and outdoor air. The air with high indoor temperature rises due to its small specific gravity and is discharged from the upper air outlet of the object. At this time, a negative pressure area will be formed in the original place of the low-density air, so the fresh air with a relatively low outdoor temperature and a large specific gravity will be discharged from the bottom of the building. Inhaled, the indoor and outdoor air flows continuously.
烟囱效应的强度与进出风口的高差、进出风口的温差、室内外的温差以及户内外空气流通的程度有关。室内外温差和进出风口的高差越大,则热压作用越明显。The strength of the chimney effect is related to the height difference between the air inlet and outlet, the temperature difference between the air inlet and outlet, the temperature difference between indoor and outdoor, and the degree of indoor and outdoor air circulation. The greater the temperature difference between indoor and outdoor and the height difference between the air inlet and outlet, the more obvious the effect of thermal pressure.
本发明的某些实施例,壳体100包括主容纳部120和出气部110,主容纳部120为容纳变压器器体300的部分。主容纳部120为六棱柱体,接近变压器器体300的形状,这能有利于减少生产材料成本和运输空间成本。In some embodiments of the present invention, the
另外,壳体100可以起到防风、防雨、防尘和防外部撞击的作用,对内部的变压器器体300具有良好的保护作用。In addition, the
本发明的某些实施例,通风道210包括设置于出气部110中的出气管道212;出气管道212的末端为出风口202,出气管道212往出风口202逐渐缩窄。由于出气管道212纵向设置,从出风口202离开的热空气被冷却,密度增大,如果从出风口202离开的热空气的流速过小,存在倒流回出风口202的问题。采用往出风口202逐渐缩窄的出气管道212,能逐渐增强沿出气管道212流动的空气流的速度,增大热空气离开出风口202时的流速,避免冷空气倒流入出风口202,增强散热效果。In some embodiments of the present invention, the
出气部110为棱台状,出气部110的横截面从下往上逐渐减小。这能使得变压器整体的重心降低,结构稳定性更佳,站立更加稳定。The
通过设置出气部110,使得位于出气部110末端的出风口202处于整个变压器的最高位置,这样有利于提升出风口202的高度,增大出风口202与进风口201的高度差。增大出风口202与进风口201的高度差能增大烟囱效应的强度,热压作用更明显,空气流更强,有利于提高变压器的散热效果。By arranging the
本发明的某些实施例,壳体100与变压器器体300之间设置有隔板400,隔板400与变压器器体300之间形成纵向的第一通风间隙213。通过隔板400充斥壳体100与变压器器体300之间的空间,使得从进风口201进来的冷空气能集中到变压器器体300位置;同时使得隔板400与变压器器体300之间形成纵向的第一通风间隙213。第一通风间隙213的宽度通常设计得较为狭窄,有利于提高通风管中的空气流的流速,提高散热效果。第一通风间隙213位于变压器器体300的外侧,第一通风间隙213中流通的空气流能带走变压器器体300的外侧的热量。当然,第一通风间隙213的宽度可以根据变压器的实际生产需求和具体结构参数确定。In some embodiments of the present invention, a
另外,隔板400采用绝缘材料制成,具有绝缘作用。In addition, the
本发明的某些实施例,通风道210包括进风管道211,进风管道211位于壳体100的下部;进风管道211的首端为进风口201。进风口201设置在外壳的外侧,则进风管道211向壳体100的内部延伸。进风管道211为圆管道式结构,使从进风口201进入的冷空气更加集中,能有效提高进风流速,提高冷空气的散热效率。In some embodiments of the present invention, the
本发明的某些实施例,进风管道211有多个;多个进风管道211围绕变压器器体300设置,且多个进风管道211的出风方向均朝向变压器器体300,使得冷空气能集中到变压器器体300的位置,有利于变压器器体300散热。In some embodiments of the present invention, there are multiple
具体地,壳体100的主容纳部120为六棱柱状,下部为六棱台状。六棱台状的下部的六个面所设置的进风口201的数量分别为2、3、1、3、1、3。对应地,每个进风口201与一条进风管道211连接,共设置有13个进风口201和13条进风管道211。Specifically, the main
本发明的某些实施例,隔板400设有与进风管道211适配的穿孔410,进风管道211插设于穿孔410中;即进风管道211的外管壁与穿孔410的内孔壁相贴,这能更好地固定进风管道211。In some embodiments of the present invention, the
本发明的某些实施例,变压器器体300为干式器体,区别于油浸式器体。变压器器体300包括铁心320和线圈310,铁心320采用立体卷铁心320结构,由电工钢带或非晶带材卷绕加工而成,得到心柱截面为近似半圆形、几何尺寸完全相同的三个矩形铁心框。三个矩形铁心框竖直放置,两两拼接,相邻的两个矩形铁心框的竖直心柱相靠;进而得到俯视方向为等边三角形的立体结构。线圈310包括a相线圈310、b相线圈310和c相线圈310共三相线圈310,该三相线圈310分别绕制在铁心320的三个竖直的心柱上,呈三角形布局。In some embodiments of the present invention, the
壳体100设有四个低压接线端子160,四个低压接线端子160呈水平排列在同一个面上,四个低压接线端子160间隔设置;四个低压接线端子160设置在同一个面上,方便接线。壳体100还设有三个高压接线端子150,三个高压接线端子150呈水平排列在另一个面上,三个高压接线端子150间隔设置;三个高压接线端子150设置在同一个面上,方便接线。高压接线端子150和低压接线端子160分别设置在不同面上,便于区别,减少接线误接率。当然在其他实施例中,低压接线端子160和高压接线端子150的数量也可以根据具体实际需求设置。通过低压接线端子160和高压接线端子150连接电缆,将变压器并入配电网中。The
基于烟囱效应的原理,变压器的烟囱效应的强度与进风口201和出风口202之间的热压差相关。增大进风口201和出风口202之间的热压差,能提高变压器的烟囱效应的强度,有利于散热。通过增大靠近进风口201的部分的温度与靠近出风口202的部分的温度之间的差值,能增大进风口201和出风口202之间的热压差。Based on the principle of the chimney effect, the intensity of the chimney effect of the transformer is related to the thermal pressure difference between the
本发明的某些实施例,线圈310的外表面设有横向的环型气道340。线圈310包括高压线圈312和低压线圈311,高压线圈312围绕在低压线圈311的外侧;即具体地,高压线圈312的外表面设有横向的环型气道340。环型气道340能增大空气接触面积,用于辅助散热。In some embodiments of the present invention, the outer surface of the
本发明的某些实施例,环型气道340有多圈,多圈环型气道340沿线圈310从下往上间隔设置,多圈环型气道340的宽度从下往上逐渐增大。则对于线圈310,其越远离出风口202的环型气道340的宽度越小,其越靠近进风口201的环型气道340的宽度越大,宽度越大的环型气道340越有利于散热。这样能使得线圈310的下部的温度比线圈310的上部的温度要高,能增大靠近进风口201的部分的温度与靠近出风口202的部分的温度之间的差值,有利于增强变压器的烟囱效应的强度。In some embodiments of the present invention, the
本发明的某些实施例,线圈310的匝数从下往上逐渐减少,线圈310的导体截面从下往上逐渐增大。In some embodiments of the present invention, the number of turns of the
则对于线圈310,越远离出风口202的线圈310部分的匝数多,越靠进风口201的线圈310部分的匝数少,匝数多的线圈310部分在工作时发热更多,导致温度更高。这样能使得线圈310的下部的温度比线圈310的上部的温度要高,能增大靠近进风口201的部分的温度与靠近出风口202的部分的温度之间的差值,有利于增强变压器的烟囱效应的强度。Then for the
另外,越远离出风口202的线圈310部分的导体截面越小,越靠进风口201的线圈310部分的导体截面越大,导体截面小的线圈310部分在工作时发热更多,导致温度更高。这样能使得线圈310的下部的温度比线圈310的上部的温度要高,能增大靠近进风口201的部分的温度与靠近出风口202的部分的温度之间的差值,有利于增强变压器的烟囱效应的强度。In addition, the conductor cross section of the
参照图3和图4,本发明的某些实施例,线圈风道330包括第一线圈风道301;高压线圈312和低压线圈311之间形成第一线圈风道301。能使通风道210中的空气流通过高压线圈312和低压线圈311的表面,将高压线圈312和低压线圈311的热量快速带走;另外,第一线圈风道301的方向为纵向,与通风道210的方向相同,与空气流的流动方向相同,使得空气流能自然通过线圈风道330,顺利带走线圈310热量,有利于对线圈310降温散热。3 and 4 , in some embodiments of the present invention, the
本发明的某些实施例,线圈风道330包括第二线圈风道302和第三线圈风道303;高压线圈312的内部形成有纵向的第三线圈风道303;低压线圈311的内部形成有纵向的第二线圈风道302。第三线圈风道303能使通风道210中的空气流通过高压线圈312内部,第二线圈风道302能使通风道210中的空气流通过低压线圈311内部,将高压线圈312和低压线圈311的热量快速带走。另外,第三线圈风道303和第二线圈风道302的方向均为纵向,与通风道210的方向相同,与空气流的流动方向相同,使得空气流能自然通过第三线圈风道303和第二线圈风道302,顺利带走线圈310热量,有利于对线圈310降温散热。In some embodiments of the present invention, the
本发明的某些实施例,壳体100的外侧边设有吊板130,通过吊板130便于起吊变压器。具体地,吊板130包括横条、纵条和钩条;横条和纵条垂直设置形成的形状为倒L型;钩条位于横条的末端,且在横条的上下方向上均凸出。纵条与壳体100的外壁面连接。In some embodiments of the present invention, a
本发明的某些实施例,壳体100的下方设有垫高底座140,垫高底座140起到承重的作用,另外垫高底座140使得壳体100远离地面,减少地面的水汽进入到壳体100中,避免水汽对壳体100内的变压器器体300造成损坏。In some embodiments of the present invention, a raised
另外,垫高底座140能使壳体100下部和位于壳体100下部中变压器器体300下部远离地面。由于地面温度通常较低,使变压器器体300下部远离地面能减少地面对变压器器体300下部的温度的影响。In addition, the raised
具体地,垫高底座140包括平行设置的两条脚条,在两条脚条之间连接有多条加固条,具体地,加固条的数量为六条。多条加固条平行设置,且加固条与脚条垂直设置。Specifically, the elevating
参照图5,本发明的某些实施例,线圈310通过压块350压紧和支撑,无需通过夹件固定和支撑。当通过夹件对线圈310进行支撑的时候,夹件体积大且会对线圈风道330造成较大面积的遮挡。当通过压块350对线圈350进行支撑的时候,对每个线圈310,只需通过3个压块350进行支撑即可,每个压块350单独与线圈连接,另外压块350的体积比夹件更小。相对于通过夹件支撑的方案,通过压块350支撑能减少对线圈310的遮挡面积,提高散热能力。Referring to FIG. 5 , in some embodiments of the present invention, the
以上所述,只是本发明的较佳实施例而已,本发明并不局限于上述实施方式,只要其以相同的手段达到本发明的技术效果,都应属于本发明的保护范围。The above descriptions are only preferred embodiments of the present invention, and the present invention is not limited to the above-mentioned embodiments, as long as the technical effects of the present invention are achieved by the same means, they should all belong to the protection scope of the present invention.
