Klimatkabinett : Komponenter och konstruktion

This report describes the construction of a climate-cabinet for testing of HV-cards (High Voltage) produced at VG Scienta. The main part of the report describes all the different components of the cabinet. The most important parts are a PID regulator from Eurotherm model 2408, a solid state contactor (SSC), a thermocouple, a finned resistor from DBK and different fans. The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods. As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB. The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010. The construction of an additional climate-cabinet was necessary because during the last year Scientas productivity increased, and it was important for the company to be able to manage the testing of an increased number of electronics. Which solution is best for the heating of a cabinet? How does the communication work between a PC and a Eurotherm 2408 regulator? How to detect the temperature inside of the cabinet? These are some of the topics which are discussed. The finished cabinet resembled the old cabinet in many ways. The difference between them is that the later one allows the testing of twice as many HV-cards, in an even more flexible way by the communication between the regulator and the computer. It means that the regulator parameters can be set continually and by programming it is possible to save the settings, the parameters and the curves.
