high voltage climate test chamber

绝缘材料的工作性能在很大程度上也取决于它们的温度。为了研究高压技术下绝缘材料及其工作性能，还在偏离室温的温度下进行了试验。在这个应用中，要求支持更换一个移动气候室（内部尺寸：WxHxD: 2300x2500x4000 mm）。它是一个温度范围为-70°C至120°C的房间。此外，还将集料分配到可对室内空气进行加湿或除湿的室中，以评估该参数及其对所研究的绝缘材料的工作性能的影响。箱室及其保温壳、制冷机、制冷回路的工艺冷却设备、加湿和除湿集料、相关的水处理和控制技术（控制柜）安装在可升降的活动框架上；使该腔室可以从FGHT高压大厅的存储区域移动到测试大厅的高压区域，以便使用位于那里的高压发电机将测试电压通过套管传导到腔室内部。然后，放置在试验室内的测试对象可以暴露在不同气候条件下的各种高压形式中，并可以在此过程中研究其操作行为。温度和湿度特性的控制是通过位于FGHT的可编程逻辑控制器网络进行的，这些控制器将通过光纤总线连接到腔室控制系统，以便能够联合控制高压源和腔室，进行无人值守的连续实验。

The operating behavior of insulating materials also depends to a large extent on their temperature. In order to investigate insulating materials in high-voltage technology and their operating behavior, tests are also carried out at temperatures deviating from room temperature. In this application, support is requested for the replacement of a mobile climatic chamber (interior dimensions WxHxD: 2300x2500x4000 mm). It is a chamber in which temperatures in the range of -70°C to 120°C can be set. Moreover, aggregates are assigned to the chamber which can humidify or dehumidify the chamber air in order to evaluate also this parameter and its effects on the operating behavior of the insulating materials under investigation. The chamber and its thermally insulating shell, the refrigerating machines, the process cooling equipment for the refrigeration circuit, the humidifying and dehumidifying aggregates, the associated water treatment and the control technology (control cabinet) are to be set up on a craneable and movable frame, so that the chamber can be moved from a storage area of the high-voltage hall of the FGHT into the high-voltage area of the test hall in order to use the high-voltage generators located there to conduct the test voltages into the interior of the chamber via a bushing. The test object positioned in the chamber can then be exposed to the various high-voltage forms under different climatic conditions and its operating behavior can be investigated in the process. The control of the temperature and humidity characteristics is carried out via the network of programmable logic controllers already located at the FGHT, which are to be connected to the chamber control system via a fiber optic bus in order to enable joint control of the high voltage sources and the chamber for unattended continuous experiments.
