摘要
The invention relates to a high-voltage switching device comprising a vacuum chamber and to a switching system comprising a high-voltage switching device. The invention further relates to a method for manufacturing a high-voltage switching device comprising a vacuum chamber. The high-voltage switching device has a cast housing 1 consisting of a casting resin, which encloses the housing body 3 of the vacuum chamber 2, which has a fixed contact 4A and a movable contact 5A, an intermediate layer 3A being provided between the inner wall of the cast housing 1 and the outer wall of the housing body 3 of the vacuum chamber 2. The high-voltage switching device is distinguished in that this intermediate layer is a casting resin layer 3A, the glass transition temperature of the casting resin layer being between 10 and 40° C. In a construction of this type, no tears in the coating or casing of the housing body of the vacuum chamber and no external flashovers on the housing body have been found in tests.
