Problems solved by technology

[0007] It should also be noted that the presence of grounding switches within the cable compartment, in addition to requiring some dedicated internal space, requires a dedicated manual or motor actuation system and a series of mechanical interlocks, resulting in increased switchboard complexity and its manufacturing and installation costs

Embodiment Construction

[0028] see figure 2 Referring to Fig. 6, the medium voltage switchboard 1 according to the invention comprises in a more general concept a housing 2 having an inner wall dividing the inner space of the housing 2 into several compartments. In particular, in the housing of the invention, said inner wall defines at least three compartments, namely a first compartment 10 , a second compartment 20 and a third compartment 30 .

[0029] The first compartment 10 is generally a circuit breaker compartment housing the circuit breaker unit 11 , the second compartment 20 is generally a bus bar compartment housing a bus bar system 21 , and the third compartment 30 is a compartment generally housing a cable system 31 Cable compartment. Additional components such as current transformers, transformers, fuses and the like can also be accommodated within the compartment.

[0030] One of the features of the switchboard according to the invention is that at least a part 12 of the wall between ...

Abstract

A Medium Voltage panel that comprises: a casing having internal walls that define at least a first (10), a second (20) and a third (20) compartment, respectively housing a circuit breaker unit (11), a bus-bar system (21) and a cable system (30), and in which at least a portion of the walls between the circuit breaker compartment and the bus-bar compartment, and between the circuit breaker compartment and the cable compartment are made of insulating material. In the panel, for each phase: the circuit breaker unit (11) comprises a first (111) and a second (112) connection contacts; a third connection contact (213) is positioned in the second compartment (20) and is connected to a corresponding bus-bar; a fourth (314) and a fifth (315) connection contacts are positioned in the third compartment (30) and are respectively connected to a corresponding cable and to ground. Also, the circuit breaker unit is movable between three positions so as to realize three different operating states of the panel.

Description

technical field [0001] The invention relates to a medium voltage switchboard, in particular to a medium voltage switchboard with a particularly compact construction and structure. For the purposes of this application, the term "medium voltage" refers to applications in the range between 1 kV and 50 kV. Background technique [0002] Medium voltage switchboards are well known in the art and are in figure 1 An example of a medium voltage switchboard is schematically shown in . A medium voltage switchboard generally consists of a housing 90 internally divided into a circuit breaker compartment 92 , a bus-bar compartment 93 , a cable compartment 94 , and a control cabinet 95 . [0003] A circuit breaker 91 is generally located within a circuit breaker compartment 92 capable of several locations for connection to bus bars and cable systems and test / disconnect locations (such as figure 1 ), in the test / disconnect position, the circuit breaker is isolated from the bus bar and cab...
