Modular high-voltage switching parts with swivel frame

The invention relates to a high-voltage switching parts, consisting of modular, interconnectable assemblies for switchgear and accessories, e.g. busbars, busbar disconnectors, Circuit breakers, converters, cable disconnectors, secondary wiring.

As in communications engineering, efforts are also underway in switchgear construction to increase the space required for such systems to decrease. To do this, different ways can be taken, e.g. by reducing the size of components or through sensible use of space through a more compact arrangement of the individual parts. There are limits to both possibilities,

which serve, among other things, for general safety. Of the already known possibilities, a switch cell for electrical switchgear should be mentioned, in which devices such as relays, measuring and control devices including their wiring are arranged in a niche that consists of profile tubes in the form of a frame (DBGM 1 936 975). Alcove and cell can be assembled on site. A disadvantage with this arrangement that the accessibility of the behind this niche arranged parts of the switch cell after expansion of the niche possible, or the cell must be accessible on two sides.

There is also a sheet metal encapsulated switchgear cabinet for high or low voltage systems known, which consists of independent cabinet parts for switching devices and their accessories (DBGM 1 681 782). The control and instrument cabinet can be swiveled out here will. The individual cabinet parts form a closed block, with the individual cabinet parts on top of each other and are arranged back to back. This means that maintenance and repair work can be walked on from both sides, which takes up additional space.

The invention is based on the object of creating a high-voltage cell in a space-saving and modular design, with the secondary wiring is designed as an easily accessible, easily replaceable and space-saving assembly that is in the essential operation and maintenance of the switchgear is only permitted from the front.

According to the invention, this object is achieved in that at least one assembly has a frame for receiving the secondary wiring is provided, which is connected on one side in a hinge-like manner to the cell front side in the vicinity of a side wall of the assembly and can be pivoted outwards.

The advantages achieved by the invention are in particular that the space behind it is opened by simply pivoting this assembly and is accessible for maintenance purposes. This means that there is no need for the operator or supervision aisle behind the switchgear cubicle in the case of double busbar systems. In the case of double busbar systems, it may be advisable. only a narrow assembly aisle about 50 cm wide. This gain in space means that the building for the switchgear can be reduced in size. This saves a considerable amount of costs. In addition, security is increased for the operator by all ^w-ended system.

It has now proven to be useful if the frame according to the invention in the assembly for the circuit breaker between the cell front and the circuit breakers is arranged, wherein the front of the assembly can be closed by a door is.

This has the advantage that the circuit breaker is particularly easily accessible after the frame has been pivoted out. Since this The current and voltage converters are also located in the assembly, so simple and safe maintenance is also guaranteed for these components.

About easy interchangeability and overhaul of the swing frame to enable, this is removably mounted according to a further embodiment of the invention.

This has the advantage that any repairs or wiring changes can be carried out on the frame regardless of the location of the switchgear. The complete swivel frame can even manufactured and tested completely independently of the switchgear will.

It should also be counted towards the invention that the secondary wiring is electrically connected within the frame with the cell via connectors.

This is advantageously quick and easy Separation of the electrical parts from each other not possible.

There are now several ways to connect the door and frame to the assembly in question. According to one embodiment of the invention, the door and the frame are on the same Arranged side of the cell.

According to a further embodiment of the invention, the Door on one side and the frame on the other side of the cell.

Finally, a further embodiment of the invention should be mentioned, the frame being pivotable on the inside of the door is arranged.

An embodiment of the invention is shown in the drawing and is described in more detail below. Ea show:

Fig. 1 shows a high-voltage switching parts in a modular design Side view in section and

Fig.? an assembly for circuit breakers with swiveling Frame in top view.

As FIG. 1 shows, the modular high-voltage cell is composed of several assemblies. The assembly 2 for the Circuit breaker 3, which also expediently includes a voltage converter 11 and a current transformer 12 are housed, has Immediately behind the cell front door 4 a pivotable one Frame 1. The pivoting frame 1 forms within the assembly 2 a closed assembly for the secondary wiring.

Fl 4190 - 5 - 18.9.74

It is also possible to accommodate the electrical lock and the selective protection in the frame 1. Below the assembly 2 is an assembly 13 for the cable disconnector 14 and the terminal compartment with the low-voltage terminals 15. Above module 2 are located depending on Requires one or two assemblies 5 and 6 with busbars 7 and 8 and busbar disconnectors 9 and 10.

As iie Fig. Ζ shows, the frame 1 can be pivoted outward when the cell front door 4 is open. The circuit breakers 3 and the current transformers 12 are thus easily accessible for maintenance and repair work. An assembly aisle behind the switchgear cubicle is indicated by 16, which is completely omitted in the version with one busbar and can be reduced to a width of about 50 cm for the version with two busbars.
