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.

绝缘材料的工作性能在很大程度上也取决于它们的温度。为了研究高压技术中的绝缘材料及其工作特性，还在偏离室温的温度下进行了测试。在此应用中，需要支持更换移动的气候室（内部尺寸WxHxD：2300 x2500 x4000 mm）。它是一个可以在-70 ° C至120°C范围内设置温度的腔室。此外，聚集体被分配给可以加湿或除湿室空气的室，以评估该参数及其对所研究的绝缘材料的操作行为的影响。该室及其隔热外壳、制冷机、制冷回路的工艺冷却设备、除湿和除湿机组、相关的水处理和控制技术（控制柜）应安装在可起重和可移动的框架上，从而可以将腔室从FGHT的高压大厅的存储区域移动到测试大厅的高压区域，位于那里的电压发生器，用于通过套管将测试电压传导到腔室内部。然后，可以将位于测试室中的测试对象暴露于不同气候条件下的各种高压形式，并在此过程中研究其操作行为。温度和湿度特性的控制通过已经位于FGHT的可编程逻辑控制器网络进行，这些控制器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。
