Protection Switch Product Introduction
For the ultimate safety of train operations, protection switches play a pivotal role at key station intersections. These switches work by integrating with specific condition-activated systems to assure unmatched safety. Unlike ordinary switches, these have to be manually or belt-operated and locked in place. The circuit system verifies the turnout's position, ensuring it's correctly locked and signaling readiness. Based on different utilization and protection requirements, turnouts are meticulously categorized as follows:
For downhills with a 6 ‰ gradient (or where braking might pose challenges), the initial group of turnouts is precisely engineered for protection. These can seamlessly transition to safety lines, special tracks, or refuge lines, ensuring smooth and secure train transitions.
At the continuation of a 6 ‰ down gradient approach terminal, protective turnouts prevent trains from overshooting exit signals due to inadequate braking. These specialized turnouts can also direct trains to safety lines, dedicated tracks, or refuge lines, and are expertly circuit-driven.
The approach terminal with a 6 ‰ gradient can feature a manually-operated leveling protection fork. Even though it's not circuit-driven, it undergoes rigorous positional checks. Positioned strategically outside, this fork ensures only the necessary light belts and signals are visible, perfect for road continuation and vehicle entry.
In areas with busy shunting operations, protective turnouts are indispensable. They are strategically placed to prevent shunting trains from inadvertently entering station lines, ensuring they remain on dedicated safety lines or shunting pull-out routes, hence optimizing operation safety.
Cross-ferry lines benefit from dual-action turnout groups designed for mutual inspection protection. If one group is in reverse, the other is safeguarded in position to prevent 'cross' collisions. This system also buffers sidestroke impacts, minimizing potential damage and ensuring seamless operations.
