Protection Switch Product Introduction
In the dynamic world of railway systems, ensuring both the safety and efficiency of train operations is paramount. This is where the pivotal role of the protection switch comes into play. Strategically positioned at key stations, these switches act as guardians of safety, working seamlessly in specific conditions to deliver ultimate protection. When not set in an automatic mode, the protection switch requires manual intervention, ensuring it remains securely locked in the correct and designated protective position. The rigorous circuit verification further guarantees the turnout's position, facilitating the flawless execution of approach locking and signal opening. Protection switches, tailored to meet diverse needs and protective criteria, are classified as follows:
When dealing with a 6‰ downhill entry—or even less, yet with braking challenges—the first group of turnouts is meticulously designed for protective purposes. These protection turnouts can be strategically opened to connect with the safety line, special line, or refuge line, ensuring an impeccable safety net for train operations.
Extending from a 6‰ down ramp at an approach terminal, protection turnouts stand as sentinels to prevent trains from overrunning the outbound signal machine when braking is insufficient upon station entry. These protection turnouts can be skillfully positioned to integrate with the safety line, dedicated line, refuge line, and other crucial routes. Notably, these forks are circuit-driven, ensuring precision and reliability.
At a 6‰ down ramp, continuing to an approach terminal, a manual maneuvering leveling protection fork can be fitted. While not circuit-driven, manual checks maintain its position, playing a crucial role when trains approach. Positioned outside the display zone of the continuation road, its opening alignment mirrors that of the display, ensuring consistency. This fork reflects external circuit signals, providing clarity on track positioning, crucial for safe navigation.
In areas with dedicated lines and busy shunting operations, protection turnouts are ingeniously designed to prevent shunting trains from inadvertently entering the main station line. These turnouts are astutely positioned towards safety lines or shunting pull-out lines, offering maximum protection during complex maneuvering activities.
Designed for absolute safety, two groups of double-acting turnouts are adeptly crafted for cross-ferry lines. They ensure that when one group is in reverse, the other remains in position, thus eliminating the risk of collisions at the crossing point. This design ensures that during sidestroke maneuvers, the buffer strength is optimized, minimizing potential losses and enhancing operational safety.
