Definitions

• the invention relates to an arrangement for connecting a circuit breaker in a control panel, in particular in a switchgear assembly, with conductors which are formed in the form of busbars and supported against each other for receiving forces that result from the normal performance and short circuit situations.
• circuit breakers are usually installed in cubicles in a switchgear assembly and connected to busbars with rails or cables.
• these rails but also cables are mechanically supported against each other to absorb the operating and short-circuit forces.
• the electrical conductors whether they be massive rails, flexible rails or cables, are electrically insulated with shrink tubing or with adhesive tape.
• CONFIRMATION COPY Based on this prior art, it is an object of the invention to provide an arrangement for connecting a circuit breaker in a control panel of the type mentioned, which is improved in terms of stationary stability of the conductor in a simple manner and with little effort.
• the conductors are arranged in at least two-part encapsulations, which enclose the relevant conductor in each case in full circumference and serve as electrical insulation.
• the conductor insulation formed from at least two encapsulations is provided or connected with holding devices which ensure that forces of the rail conductors resulting from the normal operating behavior and from short-circuit situations are reliably removed.
• the arrangement, support and isolation of the rails by means of encapsulations which are preferably formed as plastic trays.
• encapsulations which are preferably formed as plastic trays.
• a lower and an upper half are provided for all outer conductors or per outer conductor or a right or left half per outer conductor.
• the trough-shaped enclosures completely surround the rails and thus provide the insulation of the rails as well as the support and the arrangement of the rails available.
• the system according to the invention is of modular design and provides in a simple and secure way the connection to the busbars but also the connection to external cables or busbar systems.
• the system offers the possibility of being able to be adapted at any time to the respective needs by the modular insulating trays with the bus bars arranged therein, by stacking the modules is provided at higher currents.
• the at least two-part encapsulation is formed from a material based on plastic, wherein the encapsulation is provided in particular with tight-fitting joints, so that, for example, the inadvertent penetration of moisture into the interior of the encapsulation is prevented.
• the arrangement according to the invention is characterized in that each at least two-part encapsulation receives only a single conductor. As a consequence, this results in several conductors being arranged separately in individually assigned encapsulations.
• conductors which are assigned to different phases are arranged in adjoining adjacent encapsulations.
• each encapsulation is manufactured as an injection molded part.
• these moldings may also be reinforced with fibers. It is also possible to produce the encapsulation of plastic plates which are provided with edgings.
• FIG. 1 shows a cross-sectional view of an arrangement of three individual conductors, each in a single encapsulation.
• Fig. 2 is a cross-sectional view of an arrangement of three-phase
• Fig. 3 is a cross-sectional view of an arrangement of three-phase
• FIG. 1 shows a cross-sectional view of three arrangements 10 with three individual conductors 14 each arranged in a single encapsulation 12, which encapsulation 12 is formed from a lower shell 16 and an upper shell 18.
• the encapsulation 12 in each case has a parting line 17, which is designed to be fluid-tight, so that no fluid, in particular no liquid, can penetrate into the interior of the encapsulation.
• FIG. 2 shows a cross-sectional view of an arrangement 22 of conductors 14, which are designed in three-phase fashion and are each arranged in individual encapsulations 12 and are largely identical in design to the arrangement 10 shown in FIG.
• the three-phase system associated conductor 14 are each arranged separately in closely juxtaposed encapsulants 12, between which no mounting aid 20 is provided and therefore virtually without spacing form an assembly 22 formed from a one-piece block.
• Each conductor 14 carries the current of the phase associated with the conductor 14, wherein, as well as in the arrangement 10 according to FIG. 1, the encapsulation serves as an electrical insulator.
• Fig. 3 is a cross-sectional view of a three-phase arrangement 24 is shown in which each phase a plurality of conductors 14 are provided, which are phase-stacked in each case stacked.
• the modular design of the insulation carried out as encapsulation 12 allows, on the one hand, its simple production and, on the other hand, a space-saving housing in the respective switching field or in the respective switching device arrangement or combination, which are not shown in more detail here.
