Description

一种大功率充电桩专用液冷电缆DC+与DC-并冷液冷电极
技术领域
本发明涉及大功率充电桩专用液冷电缆领域，尤其涉及一种大功率充电桩专用液冷电缆DC+与DC-并冷液冷电极。它是大功率充电桩专用液冷电缆上的一个集成组合件,用于制造大功率充电桩专用液冷电缆。
背景技术
公知的，中功率充电桩的技术参数:直流电压是750伏,标称电流250安培。中功率充电桩的电源与中功率充电枪的连接,用的是干式电缆。干式电缆的结构,它的外圆直径40毫米,内部集成有:红色、黑色两根动力线,每根动力线导体的截面70平方毫米。PE地线导体的截面25平方毫米，还有14根信号线。这种中功率充电桩干式电缆，它的两根直流充电动力线DC+和DC-，当充电电流达到250安培时,因为散热条件不好,干式电缆导线的温度、充电枪接线端子的温度、干式电缆的接头铜鼻子的温度过高，而不能使用。
大功率充电桩技术参数:直流充电电压1000～1500伏，输出电流500～600安培。大功率充电桩输出的最大电流是600安培。它的两根直流充电动力线DC+和DC-要承载电流600安培;电缆接头和充电枪的端子DC+和DC-也都要承载600安培的电流。这两根直流充电动力线DC+和DC-，若使用上述的干式电缆,每根动力线导体的截面,由原来的70平方毫米至少要增大到200平方毫米。与这两根直流充电动力线DC+和DC-两端连接的接头，一端是铜鼻子，它连接电源；另一端是充电枪端子，是装到充电枪里面用的。大功率充电桩若使用中功率干式集成电缆,它的外径由原来的40毫米就要增大到100毫米。充电枪的接线端子外径由12毫米就要增大到28毫米，充电枪的体积也会增大2到3倍。直径这么大的电缆,直径这么大的接线端子,体积这么大的充电抢；操作工人是拿不动的，无法使用毫无价值。由此看来干式电缆是不能用于大功率充电桩的。
实用新型内容
本发明的目的是为了解决现有技术中存在的缺点，而提出的大功率充电桩专用液冷电缆DC+与DC-并冷液冷电极。
为了实现上述目的，本发明采用了如下技术方案：
一种大功率充电桩专用液冷电缆DC+与DC-并冷液冷电极，包括电极管道、电缆电极进液口和导线连接口，所述电缆电极进液口和导线连接口分别设置在电极管道两端，所述电极管道的管壁上还设置有联通管道内外侧的出液口和安装座；所述电缆电极通过导线连接口与导线连接。
为了进一步改进技术方案，本发明所述进液口与出液口的端部内表面上均设置有内螺纹，所述电缆电极的电缆电极进液口上连接有进液口快接接头，电缆电极出液口上连接有出液口快接接头。
与现有技术相比，本发明的有益效果是：本发明大功率充电桩专用液冷电缆DC+与DC-并冷液冷电极有以下的特点:1大功率充电桩专用水冷电缆电极上设置进水口和出水口,而大功率充电枪专用水冷端子上不设置进水口和出水口。这样做可以使大功率充电枪专用水冷端子的体积比中功率充电枪端子的体积更小。这样可使充电枪的体积减小,可以减低生产成本。充电枪的体积减小操作工人使用会更加方便。2大功率充电桩专用的两根水冷电缆DC+和DC-,各自的冷却水路独立,而不串接,与两根电缆冷却水路串接的结构相比耗能要少。这种结构在公知的水冷电缆领域没有类似的，没有可比性。
