LINEAR MOTOR VARIABLE-FREQUENCY DRIVE-BASED SWITCH SYSTEM AND WORKING METHOD THEREFOR

摘要

A switch system and a working method therefor of a linear motor variable-frequency drive technology. The system comprises a switch (3), a controller (1), a sensing module, and a variable-frequency power supply (2). The switch (3) comprises a housing (4). The housing (4) is provided with a linear motor (5), an acting mechanism (6), a locking module (7), and a detecting mechanism (8). The acting mechanism (6) and the detecting mechanism (8) respectively are connected to a turnout via external rod elements. The locking module (7) can be respectively connected to or separated from the acting mechanism (6) and the detecting mechanism (8). The sensing module is connected to the controller (1) and senses position information of the linear motor (5), of the acting mechanism (6), and of the detecting mechanism (8). The controller (1) is connected to the variable-frequency power supply (2). The variable-frequency power supply (2) is connected respectively to the linear motor (5) and to the locking module (7). The system is structurally simple and the transmission efficiency is high.
