- 9 - Abstract A device for the determination of the quantitative composition of gases The device is used in the determination of the quan- titative composition of gases dissolved in the insulating oil of oil-insulated electrical apparatus. It consists of a device for removing insulating oil samples, a pump ar- rangement for the extraction of the gases from the insu- lating oil sample by means of reduced pressure and for con- veying it to an analytical section. This device is inten- ded to operate directly on the electrical apparatus to be investigated. This is achieved in that the device is con- structed in a transportable manner and incorporates a peri- staltically operating pump arrangement. This pump arrange- ment contains at least one peristaltic pump (13), whose inlet can be connected via an extraction vessel (8) with the removal device and whose outlet can be connected op- tionally with the outside air or with a gas collecting vessel (16). The gases from the gas collecting vessel (16 are analysed in the analytical section. (Figure 2)
