Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
206 words
A low voltage electrical switchboard comprising: a housing having a front panel and a rear panel; a plurality of superposed compartments accessible via said front panel of the switchboard; electrical power devices housed in said superposed compartments; a busbar compartment located in close proximity to said rear panel of the switchboard for supplying power to said electrical power devices; outgoing cables connecting said electrical power devices to a plurality of superposed rear compartments; conduit means generally forming a column and having a modular construction, said conduit means being located in close proximity to said front panel such that a vertical portion of said conduit means is accessible via said front panel; a plurality of enclosures arranged in superposition in said conduit means; printed circuit board means fixed in said enclosures for providing an indication and/or control interface to the corresponding electrical power devices, each said printed circuit board means being located at approximately a same vertical position as the corresponding electrical power device within the housing; and indicator panels containing indication and/or control devices for providing a customer interface to said printed circuit board means and thereby an interface to said electrical power devices, said indicator panels being arranged on a front portion of said enclosures.
Claim 2
Dependent Claim
206 words
A low voltage electrical switchboard comprising: a housing having a front panel and a rear panel; a plurality of superposed compartments accessible via said front panel of the switchboard; electrical power devices housed in said superposed compartments; a busbar compartment located in close proximity to said rear panel of the switchboard for supplying power to said electrical power devices; outgoing cables connecting said electrical power devices to a plurality of superposed rear compartments; conduit means generally forming a column and having a modular construction, said conduit means being located in close proximity to said front panel such that a vertical portion of said conduit means is accessible via said front panel; a plurality of enclosures arranged in superposition in said conduit means; printed circuit board means fixed in said enclosures for providing an indication and/or control interface to the corresponding electrical power devices, each said printed circuit board means being located at approximately a same vertical position as the corresponding electrical power device within the housing; and indicator panels containing indication and/or control devices for providing a customer interface to said printed circuit board means and thereby an interface to said electrical power devices, said indicator panels being arranged on a front portion of said enclosures.
Claim 3
Dependent Claim
41 words
The switchboard according to claim 1, wherein said conduit means comprises two uprights, each comprising a plurality of perforations arranged vertically along said uprights, said enclosures being arranged vertically along said two uprights and spaced according to locations of said perforations.
Claim 4
Dependent Claim
32 words
The switchboard according to claim 2, wherein said printed circuit board means bear a standard printed circuit and are customized by mounting suitable components thereon and by using a corresponding indicator panel.
Claim 5
Dependent Claim
64 words
The switchboard according to claim 3, wherein each enclosure comprises a backplane connector having, on one side thereof, a plug-in terminal block for connection to said circuit board means housed in a corresponding said enclosure, and, on the opposite side thereof, a terminal block for connection of wiring connections to a corresponding said electrical device and/or to an external device via an external connector.
Claim 6
Dependent Claim
36 words
The switchboard according to claim 1, wherein a modular label identifying the characteristics of a particular electrical power device is fixed to said conduit means above said indicator panel corresponding to said particular electrical power device.
Claim 7
Dependent Claim
36 words
The switchboard according to claim 5, wherein a difference between a combined height of said plurality of superposed compartments and a combined height of said plurality of said enclosures is compensated by labels of suitable height.
Claim 8
Dependent Claim
30 words
The switchboard according to claim 2, wherein one of said uprights has a groove formed therein, and arranged in said groove is at least one component supporting a marking arrow.
Claim 9
Dependent Claim
26 words
The switchboard according to claim 1, wherein said conduit means housing said enclosures is fitted between said superposed compartments and a compartment housing an external connector.
