Description

一种新型复合热管载流体 技术领域  A novel composite heat pipe carrier fluid technology field
本发明涉及电力设备， 尤其涉及电力设备中用来传导电流的载流体。 例如， 高压套管、 电流互感器、 大电流母线以及断路器中的导体。  The present invention relates to electrical equipment, and more particularly to a carrier fluid for conducting current in an electrical equipment. For example, high voltage bushings, current transformers, high current busses, and conductors in circuit breakers.
说  Say
背景技术 Background technique
载流体是电力设备中用来传导电流的主要部件。 载流体的例子包括电 器设备中套管的载流体， 电流互感器一次绕组的载流体， 大电流母线以及 其他电器中用于传导电流的载流体。 书  The carrier fluid is the main component used to conduct current in electrical equipment. Examples of carrier fluids include the carrier fluid of the casing in the electrical equipment, the carrier fluid of the primary winding of the current transformer, the high current busbar, and the carrier fluid used to conduct the current in other electrical appliances. Book
电力设备中的载流体一般都是用铜、 铝或其他金属材料的导体制成， 当电流流过载流体时， 由于电流的热效应使导体发热。 如果热量超过导体 或导体外绝缘材料的限度， 则势必会引起导体或绝缘的损坏， 长期运行后 势必造成电力设备的损坏， 从而引起电网的停电， 造成很大损失。 由于发 热量与电流的平方成正比， 所以， 当设备的额定电流很大时， 发热量大大 增加。 对于电压很高的设备， 由于绝缘体的厚度增加， 散热不利， 导体和 绝缘体发热的问题就更加严重。  The carrier fluid in power equipment is generally made of a conductor of copper, aluminum or other metallic materials. When the current flows through the fluid, the conductor heats up due to the thermal effect of the current. If the heat exceeds the limit of the insulating material outside the conductor or conductor, it will inevitably cause damage to the conductor or insulation. After long-term operation, it will inevitably cause damage to the power equipment, causing power outage of the power grid and causing great loss. Since the heat is proportional to the square of the current, when the rated current of the device is large, the amount of heat is greatly increased. For devices with high voltages, the heat dissipation is unfavorable due to the increased thickness of the insulator, and the problem of heat generation of the conductors and insulators is more serious.
从理论上讲可以通过增大载流体的横截面积来控制温升， 但如果仅仅 依靠增大载流体的横截面积来控制温升， 一方面会造成极大的原材料及能 源浪费， 另一方面也增加了制造过程中难度， 甚至无法实现。 例如， 对于 220kV等级的电流互感器， 当额定电流为 2000A时， 导体直径大约为 54mm; 当额定电流为 3000A时， 导体直径将接近 90mm。 这样不仅多用 了导体材料， 加工更困难 （例如， 导体截面越大， 弯曲越困难） ， 需要用 的绝缘材料也更多。 如果电压等级更高， 则绝缘材料的厚度还需要进一步 增加， 散热更为困难， 为此需要进一步增加导体截面， 问题就变得更为突 出。 In theory, it is possible to control the temperature rise by increasing the cross-sectional area of the carrier fluid, but if only relying on increasing the cross-sectional area of the carrier fluid to control the temperature rise, on the one hand, it will cause great waste of raw materials and energy, and another Aspects also increase the difficulty of the manufacturing process, and even impossible to achieve. For example, for a 220kV class current transformer, when the rated current is 2000A, the conductor diameter is about 54mm ; when the rated current is 3000A, the conductor diameter will be close to 90mm. In this way, not only the conductor material is used more, but also the processing is more difficult (for example, the larger the conductor cross section, the more difficult the bending is), and the more insulating material is required. If the voltage level is higher, the thickness of the insulating material needs to be further increased, and heat dissipation is more difficult. Therefore, the conductor cross section needs to be further increased, and the problem becomes more prominent.
因此在这一领域中， 众人一直在试图制造出截面积相对较小， 承载电 流相对较大， 内部温升不会过高的新型载流体。 发明内容 Therefore, in this field, everyone has been trying to create a relatively small cross-sectional area, carrying electricity A new type of carrier fluid with a relatively large flow and an internal temperature rise that is not too high. Summary of the invention
本发明目的在于克服现有技术不足， 开发出具有较小截面、 散热良 好、 温升很低的载流体， 解决高电压、 大电流电气设备载流体过热的难 题。  The object of the present invention is to overcome the deficiencies of the prior art and to develop a carrier fluid having a small cross section, good heat dissipation and low temperature rise, and solving the problem of overheating of a high voltage, high current electrical equipment carrier fluid.

与现有技术比较， 本发明的新型复合热管载流体具有以下优点- 第一， 由于通过复合热管载流体降低了载流体的温度， 解决了大电 流、 髙电压产品的载流体过热这一制造难题。 不仅可以减小载流体的截 面， 节约有色金属资源， 降低产品的成本， 并且有利于电力设备的安全运 行。 例如， 应用本发明的技术， 对于 220kV等级的电流互感器， 当额定电 流为 3000A时， 导体横截面积可由约 68.6cm2降低到约 9.4cm2。 对于一根 长度为 5m的导体， 重量可由约 283kg降低到约 41.9kg， 可以节约 241 kg 铜。 Compared with the prior art, the novel composite heat pipe carrier fluid of the present invention has the following advantages - first, because the temperature of the carrier fluid is lowered by the composite heat pipe carrier fluid, the manufacturing problem of the carrier fluid overheating of the high current and the krypton voltage product is solved. . Not only can the cross section of the carrier fluid be reduced, the non-ferrous metal resources are saved, the cost of the product is reduced, and the safe operation of the power equipment is facilitated. For example, application of the techniques of this invention, the current transformer for 220kV level, when the rated current of 3000A, the conductor cross-sectional area can be reduced to about 68.6cm 2 to about 9.4cm 2.

本发明将重力热管技术应用于载流体中， 从而构成了一种新型复合热 管载流体， 其包括热管导芯和设备线夹两部分。 热管导芯包括金属导电 管、 密封件、 散热器、 热管工作流体、 隔热层和导电层等， 还可以包括温 度传感器、 温度显示器等， 这些具体组成部分将在下文中更详细地描述。 设备线夹用于将热管导芯与外部高压引线相连接， 以将电流导入载流体及 从载流体中导出。 根据本发明， 向管状金属导体内灌注一定量低沸点， 无毒、 无腐蚀性 的液体作为热管工作流体后， 将该管状金属导体密封或通过抽出空气而使 管内气压低于 1个标准大气压后密封。 由于通过电流后使金属导体发热， 致使金属导体底部的液体迅速蒸发， 所产生的蒸汽上升并经与金属导体上 端相连的散热器向周围环境放热， 蒸汽放热后重新凝结成液体并在重力作 用下回流到金属导体的底部， 循环往复， 使金属导体迅速降温。 The invention applies the gravity heat pipe technology to the carrier fluid, thereby constituting a novel composite heat pipe carrier fluid, which comprises a heat pipe guide core and a device clamp. The heat pipe lead includes a metal conductive tube, a seal, a heat sink, a heat pipe working fluid, a heat insulating layer, a conductive layer, and the like, and may also include a temperature sensor, a temperature display, etc., which are described in more detail below. The device clamp is used to connect the heat pipe lead to the external high voltage lead to direct current into and out of the carrier fluid. According to the present invention, after injecting a certain amount of a low-boiling, non-toxic, non-corrosive liquid into the tubular metal conductor as a heat pipe working fluid, the tubular metal conductor is sealed or the air pressure in the tube is lower than 1 standard atmosphere after the air is extracted. seal. Since the metal conductor heats up after passing the current, the liquid at the bottom of the metal conductor evaporates rapidly, and the generated steam rises and radiates heat to the surrounding environment through the heat sink connected to the upper end of the metal conductor, and the steam reheats and then recondenses into a liquid and is in gravity. Under the action, it flows back to the bottom of the metal conductor, and reciprocates to cool the metal conductor quickly.
如上所述， 根据本发明， 热管工作流体在放热凝结后是依靠自身的重 力作用流回金属导电管底部的。 热管导芯可以呈 " 1 "字形或 "U"形， 或 任何其他合适的形状。 为了有利于液体回流， 在工作状态下， 优选地 " 1 "字形的热管导芯与地面之间所夹锐角在 15 ° 〜90 ° 之间或垂直地 面， "U" 形的热管导芯两臂之间的夹角在 0 ° 〜90° 之间。 但是， 以上 的角度仅仅是例子， 只要热管工作流体在放热凝结后能依靠自身的重力作 用流回金属导电管底部， 任何其他角度都是可以的。  As described above, according to the present invention, the heat pipe working fluid flows back to the bottom of the metal conductive pipe by its own gravity after the heat condensation. The heat pipe lead can be "1" or "U" shaped, or any other suitable shape. In order to facilitate the liquid recirculation, in the working state, preferably the "1"-shaped heat pipe guide core and the ground are separated by an acute angle between 15 ° and 90 ° or vertical ground, and the "U"-shaped heat pipe guide core has two arms. The angle between the two is between 0 ° and 90 °. However, the above angle is only an example, as long as the heat pipe working fluid can flow back to the bottom of the metal conductive tube by its own gravity after the heat condensation, any other angle is possible.
优选的在金属导电管的外表面固定一层隔热体， 在该隔热层的表面设 置导体或半导体材料的导电层， 并与金属导电管电连接。 所述隔热层用于 降低包绕在热管导芯'外的绝缘体的温度， 同时增加热管导芯的机械强度。 所述导电层由导体或半导体薄膜构成， 其与金属导电管具有相同的电位。  Preferably, a heat insulator is fixed on the outer surface of the metal conductive tube, and a conductive layer of a conductor or a semiconductor material is disposed on the surface of the heat insulating layer and electrically connected to the metal conductive tube. The insulating layer serves to reduce the temperature of the insulator surrounding the heat pipe lead, while increasing the mechanical strength of the heat pipe lead. The conductive layer is composed of a conductor or a semiconductor film having the same potential as the metal conductive tube.
