Protection Switch Product Introduction
To ensure the utmost safety of trains, protection switches are crucial at various station points. These switches engage under specific conditions to provide comprehensive safety. When not arranged in specific approaches, they require belt or manual manipulation and must be locked. The circuit checks the turnout's position to verify accuracy and locks it in the protective stance, enabling complete approach locking and signal activation. Distinct usage and protection requirements categorize these turnouts.
In scenarios with a 6 ‰ downhill entry—or even lesser gradients posing braking challenges—the first group of turnouts are specially designed for safety. These protection turnouts can direct trains to a designated safety line, a special line, or a refuge path, ensuring safe operations.
With a 6 ‰ down ramp continuing at the approach's end, protective turnouts prevent trains from overrunning outbound signal machines into other paths. These turnouts can be directed to safety lines, dedicated lines, or refuge lines, and are circuit-driven to guarantee precise positioning.
At the terminal of a 6 ‰ down ramp continuation, a leveling protection fork might be installed, operated manually rather than by circuit. Despite manual operation, the fork still ensures position checking, mostly featuring outer display for road continuation, aligning with road signals.
In areas with dedicated lines and bustling shunting operations, protection turnouts are essential to prevent incidental transfer to main station lines during shunting. These safety-designed turnouts generally lead to dedicated safety lines or shunting train pull-out paths, ensuring controlled operations.
Double-acting turnout pairs over cross-ferry lines are designed for mutual inspection protection. When one group is in reverse, the other must be secured, preventing conflict by ensuring one group remains in positioning. This arrangement safeguards against collisions across ferry lines, buffering sidestroke impacts.
