How is the design of power supply systemsMarch 23, 2018
In the complex of engineering communications design for buildings and individual structures, one of the most crucial and challenging stages is the design of power supply systems for them. The fact is that the whole system of their life-support largely depends on the efficient supply of energy to modern settlements. In addition, the power supply poses a considerable danger to ordinary people, therefore, their organization should take into account electrical safety points.
The design of the power supply system, as well as other utilities necessary for the building, begins with the receipt of permits for connecting to the existing segments of the networks, in particular to the power grids. It will also require the implementation of that stage of technical measures that will ensure such a connection.In this case, in order to get a positive decision on connecting to the system with a certain capacity, the developer will be required to calculate the required electric power capacities. The total permitted power is not allowed to exceed.
Only construction and design organizations with appropriate tolerances can engage in the design, as well as the subsequent implementation of installation work for power supply. When designing, specialists are based primarily on such characteristics as the type of electrical wiring and its design section. Also calculated and the normative reserve for the section, which will act as insurance for a situation in which the rated power or voltage will be exceeded. Various types of switching devices are selected: distribution box with terminal block, sockets, switches, starters, wires and cables.
At the next stage, you can begin to define the scheme for future electrical wiring, as well as the selection of appropriate wiring accessories and electrical equipment. Modern wiring schemes are increasingly hidden,therefore, their installation can be combined with the laying of an additional cable, in particular, for such an element as fiber-optic networks, for them specialists use not only wires, but also a splitter, as well as a refractometer, etc.
In any case, after the completion of electrical work, representatives of the project organization are obliged to provide a scheme of all electrical wiring, which later will be required by a specialist for its effective maintenance.
In the end, it remains only to agree on the project system of power supply with the electrical company, for which you will need to provide a special package of documents and go through the acceptance procedure for maintenance.
