Title:
SECTIONING POST UNINTERRUPTIBLE FLEXIBLE ELECTRICAL PHASE SEPARATION DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/093859
Kind Code:
A1
Abstract:
Disclosed are a sectioning post uninterruptible flexible electrical phase separation device and a control method therefor, the device comprising: a single-phase isolation transformer (T T), a main circuit breaker (S), a first voltage sensor (PT 0) to a fourth voltage sensor (PT 3), a two-phase back-to-back converter (BLQ) sharing a direct-current side capacitor, a converter current sensor (CT 0), and pantograph position and current sensing mechanisms (CLT 1, CLT 2). By means of the device, by adjusting voltage and current amplitudes and the phase of a neutral section, the problems of transition area arcing and inaccurate pantograph position detection of a flexible automatic passing phase separation apparatus can be solved, thereby ensuring that an electric train passes through a phase separation area stably and uninterruptedly, and fully meeting the requirements of a high-speed heavy-haul train for a traction power supply system.
