Compressed air supply system, in particular for high-voltage switchgear

The invention relates to a compressed air supply system, in particular for high-voltage switchgear with at least one generator, at least one storage pressure vessel, a control unit and with additional equipment such as a safety valve, pressure gauge, switching valves, water separator and water receiving vessel.

A compressed air supply system is already from DE-GM 80 05 438 known, in which a compressor housing has a bottom part which carries a compressor unit, wherein the bottom part with the compressor unit is arranged pull-out in the housing. The one for a compressed air supply system further required pressure vessel and distribution facilities are apparently known in this compressor arranged next to or behind the compressor housing. The known arrangement has various disadvantages, which in particular consist in that a large installation area and considerable expenditure for (individual) foundations of the units and their piping (connection) are necessary. The assembly effort is also very high and the units are relatively difficult to replace in the event of maintenance or malfunction because they are permanently piped.

The invention is therefore based on the object of a compressed air supply system to create, in which the generator and storage units, including the piping, are built on a small area and have uniform structural elements (profiles, sheet metal covers) and can be easily replaced in the event of maintenance or malfunction let or enable access to compact arrangements.

This object is achieved according to the invention in that the or the Generator units and the control unit are arranged in a stationary frame and the storage pressure tank or tanks are arranged in a mobile frame and that the devices arranged in the racks are connected to one another by means of flexible lines.

The solution according to the invention provides a compressed air supply system built with uniform components in the smallest of spaces, which can be seen as a ready-to-connect and tested unit. The different Units are arranged in a functional and maintenance-friendly manner. A universal extension in case of need is guaranteed in the simplest way. The arrangement is also suitable for transport. I.

One embodiment of the invention provides that in the stationary frame |

two generator sets are arranged one above the other. This refinement |

make, according to a further embodiment of the invention, they are on | pull-out slide arranged.

The control unit is very conveniently arranged in a 19 "rack, the is attached in the stationary frame above the generator unit (s).

In a space-saving way, the additional facilities such as Switching valve, pressure gauge, switching valves, water separator and water

receiving vessel in the stationary frame next to the generator unit (s) and the control unit.

For quick and easy connection of several storage pressure vessels on different mobile racks, the racks or the Storage pressure vessel on corresponding coupling elements.

Further embodiments of the invention provide that four storage pressure vessels in the mobile frame on a square plate are arranged upright and that the storage pressure vessel are tightly piped.

In a very advantageous manner, contactless sensors are used to detect the pressure Measured value transmitter provided with an inductive remote transmitter that is not subject to wear.

Another stationary frame can be used for a central reduction from Storage pressure should be provided for the operating pressure if no local pressure reduction is to take place on the circuit breakers.

The compressed air supply system shown in the drawing has a stationary frame 2, which can also be designed as a cabinet with corresponding panels, not shown, and in the two generator units 4, 6 on top of each other in the right part of the pull-out Carriages 8, 10 are arranged over the generator units 4, 6 is an electrical control unit with a program for the various operating conditions, operating hours counter in at least one 19 "rack and command devices arranged. In the right part of the stationary frame 2, a condensate collecting container 12 is housed below. Above this, mounted on a cross strut 14, there is a damper 16 for the pressure reduction. Above the damper are different Arranged valves with which connections from the generator units 4, 6 via flexible hoses 18, 20 to storage pressure vessels 22 can be closed or to be opened, over the valves is in the stationary frame 2 a pressure measuring device 24 with an inductive remote transmitter 24 and a safety and pressure holding valve 26 are arranged.

The compressed air supply system also includes a mobile frame 28, in which the storage pressure vessel consisting of four compressed air cylinders 30 22 is arranged. The compressed air bottles 30 are arranged and fastened in a vertical position on a square holding plate 32. In the upper part they are held together by a band 34. At a front longitudinal spar 36 of the frame 28 are as a conclusion of the flexible Hoses 18, 20 valves 38, 40 for "ON" and "OFF" attached. In addition, a drain valve 42 is provided in the lower area. the Compressed air bottles 30 of the storage pressure vessel 22 are permanently piped. At the valves 38, 40 and the corresponding valves in the stationary Gesteli 2 are useful quick-release couplings for the flexible hoses 18, 20 provided.

Due to the modular structure of the compressed air supply system with mobile Units and the flexible hoses a problem-free and quick exchange of the storage pressure vessel is guaranteed in any case. It is also possible to continue operating the system during tests.
