Title:
AUTOMATIC MEDIUM-VOLTAGE TRANSFER SWITCHING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2019/041545
Kind Code:
A1
Abstract:
Automatic medium-voltage transfer switching equipment, comprising a control system, wherein the control system is configured with three transfer modes: an automatic transfer mode, an on-site transfer mode and a remote control transfer mode. When the control system enters any of the transfer modes, the other two transfer modes are locked, thereby preventing the occurrence of a logic confusion phenomenon caused by multi-command operations. The automatic medium-voltage transfer switching equipment uses two vacuum circuit breakers having mechanical and electrical interlocking to carry out handover, can serve as an automatic incoming line transfer switching application having a selective line fault protection function, and can also be independently applied to a special purpose automatic dual-power supply handover switch application.
