Modular components for building power factor correction, filtering and snubbing circuitry

Abstract

The present invention relates to modular assemblies for building power factor correction, filtering and snubbing circuitry. The first modular unit includes a first section that houses the busbar, standard fuse holders, fuses and the busbar as protection from accidental contact with the busbar and / or fuse and a slot-shaped second section The cover and the second section accommodate the switching assembly or switching device so that it can be mechanically secured and electrically contacted. The second modular unit is designed to accommodate one or more, in particular switchable, capacitor winding blocks, surrounding and insulating the blocks. The first and second modular units each have a base region in which the mechanical and / or electrical connections are guided through apertures or openings such that back-to-back assembly of the first and second modular units by direct abutment, or belt connection, is possible The compact choke set of elements can be mechanically accommodated and electrically connected between the first and second units in an electrically insulated manner with apertures or openings in corresponding base regions of the first or second units.

Description

technical field [0001] The invention relates to a modular assembly for the purpose-built construction of power factor correction filters and snubber circuit systems with selectively unchoked, choked, protective or thyristor-connected design, comprising a busbar system , a plurality of fuse clips, a plurality of switching devices, at least one choke coil, and a plurality of power capacitors. Background technique [0002] Power factor correction systems of unchoked or choked design form part of the prior art. Such systems are generally used for central power factor correction in a connection-ready manner in low-voltage three-phase power systems with low or elevated harmonic loads. These systems generally include: a busbar system with multiple busbar supports and multiple low-voltage high-breaking capacity fuse elements for installing the busbars, multiple switchgears, multiple choke coils and multiple low-loss anti-overvoltage self-healing capacitors. [0003] These individ...

AI Technical Summary

Problems solved by technology

[0004] Since busbar supports, busbars, fuse elements, discrete switching devices, filter circuit chokes, and a relatively large number of capacitors require assembly and require a chassis, the overall cost of such a correction module and a system built from it is Considerable weight and size

In addition, the required separate components and discrete windings result in a high level of expenditure on components
