Problems solved by technology

With reference to this solution where these two electronic devices are located in the same functional unit, in the switchboard of the invention, the increased complexity and cost due to double intelligence is avoided, since the same functions are concentrated in a single IED, thus Coordination and communication problems are avoided

Embodiment Construction

[0029] figure 1 as well as Figures 3 to 6 The block diagram shown shows the switching board according to the invention in detail. With reference to said figures, a switchboard 1 comprises: at least one functional unit (mounting board) 2 , a switchgear compartment 3 and intelligent electronics 4 . Box 10 represents the auxiliary power supply unit. Another possible alternative is represented by a self-contained power supply unit, which can be centralized at the switching board level 11 or distributed at the switching component level 12 . The communication lines 100 and 101 enable communication with other intelligent electronic devices 15 , between the intelligent device 4 and the substation operating computer 13 , and / or with the human machine interface 14 at switchboard level. Other inputs 50 are also possible. At the functional unit level, box 21 represents the lock actuator function, while 22 is the mounting board / switch board terminal block. At switchgear component le...

Abstract

An electric power distribution switchboard (1) in which one or more functional units are equipped with a switching device compartment (3) that integrates primary and secondary functions. Within the switching device compartment (3) are included, together with the switching device (37), the current and voltage sensors(36), the position sensors for interlocking, a human machine interface (HMI) and an Intelligent Electronic Device (IED) (4) and the related local configuration point (32) to configure the IED (4). The IED (4) realizes functional unit supervision, control, protection, communication and monitoring and acts as a concentrating point of functional unit information and decisions. The switchboard (1) of the invention further comprises power supply section, an I / O section and a communication system.

Description

technical field [0001] The present invention relates to a medium voltage distribution switchboard with advanced integrated functional blocks. Background technique [0002] In current electrical energy distribution system architectures, switchboards function as nodes, while cables and overhead lines represent the connections between the nodes. [0003] According to this solution, all required system management functions that have to be handled for power distribution are centralized in the switchboard. These functions have historically been divided into two distinct types: primary functions and quadratic functions. [0004] All functions related to main voltage distribution, main current distribution and main power distribution are called primary functions, while all functions related to auxiliary and control features are called secondary functions. [0005] Some examples of one-time functions are: [0006] Make, break, conduct nominal current, withstand short-circuit curre...
