Abstract
Railway transportation is national economy important support, railway signal is the main measures to ensure safety and increase transport capacity. 6502 relay interlocking is a rail safety control system which is composed of relay circuit. It is a high efficient and safe station interlocking equipment. The design is based on the assigned railway yard scale drawing and based on the foundation under the general theory, methods, construction of 6502 electrical interlocking engineering design to finish the electrical interlocking design of the down throat Leshang station. The main content includes the following sections:
(1) To design the signal layout diagram which includes signal arrangement and the calculation of the coordinate of the signal, switch and fouling post, as well as the calculation of effective length of the fields.
(2) To complete the interlocking table and design the console panel diagram based on the station signal layout.
(3) To finish the design for double-track circuit diagram through the polarity cross, track circuit sends and accepts electricity, and the reasonable arrangement of impedance transformer.
(4) Cable network diagram must be based on the correct selection of cable types and connection. Drawing connection devices into tree diagram according to calculation of cable network cores. Completing cable pathway diagram and length calculation.
(5) To choose the right combination type to complete combination connection diagram according to yard diagram. According to \shape arrangement method to complete table arrangement.
(6) To complete indoor layout of equipment according to the signal equipment arrangement in signal tower.
The design is composed by the diagrams and paper. The diagrams reflect the configuration of indoor and outdoor equipments which is the basis of the design. The paper is the detailed explanation of the diagrams and explains the design method and theory.
