SISMODCOMPROT - A modern system of commutation and protection of the electrical power lines in the railway transport in view of alignment to the requirements of the European system
Overview
Background & policy context:
Presently, the electrical power lines of the railway transport system are equipped with interrupters and separators outrun both morally and physically, actioned by old systems with low reliability and durability.
Also, the isolation level of the existing equipment is of 80 kV, compared to the 200 kV required by the European norms.
In order to align the electrical system within the Romanian Railways National Company (SNCFR), modern equipment was needed to be designed and implemented, using the best commutation method, i.e. in vacuum commutation, which presents technical characteristics compliant at European level.
Objectives:
The project is financed by the AMTRANS programme, contract 6C10/2003, with the amount of 4.927 billion ROL, with a cofinancing from the project co-ordinator S.C. ICPE S.A. of 3.033 billion ROL, the total amount raising to 7.960 billion ROL.
The project aims to design, achieve and homologate in zero series phase of:
- a system for separating the electrical power lines of the rail transport, at a voltage of 27,5 kV, 630 A using in vacuum commutation, with technical parameters of European level;
- a system of provisioning and protection of the electrical power lines of the rail transport, at a voltage of 27,5 kV - 1250 A using in vacuum commutation, with technical parameters of European level.
Both systems are activated by the most modern system, consisting of an electromagnet equipped with high power permanent magnets, which have a mechanical endurance at least double compared to the classical systems with reinforcing engine and springs.
Methodology:
The project co-ordinator, S.C. ICPE S.A. Bucharest will draft the execution design, execute both systems in its own manufacturing plant and make the type testings.
The Polytechnical University of Bucharest (UPB), will provide technical assistance for establishing solutions, perform the mechanical-cynematical calculations and participate in the type testings.
