Abstract
The present disclosure relates to an automatic transportation system that moves along a rail and is powered by induction feeding, and more particularly, to a terminal block configured to facilitate installation and extension of a cable for a configuration of an induction power track and to prevent a fire accident due to overheating in advance by an overheat detection unit provided therein and an automatic transportation system using the same.
Claims15
An automatic transportation system moving along a rail and receiving electric power by inductive feeding, the automatic transportation system comprising:
- a induction power cable installed along the rail;
- a induction power track configured as a closed loop by connecting one or more induction power cables to each other;
- an inverter configured to apply an alternating current (AC) to the induction power track;
- a lead-in cable configured to connect an output from the inverter to the induction power track;
- a heat sensing wire installed inside or outside the induction power cable or the lead-in cable and configured to detect heating of the cable;
- a detection device installed inside the inverter and configured to detect an open/short of the heat sensing wire;
- and
- a terminal block configured to connect one or more induction power cables to each other or connect the induction power cable to the lead-in cable,
- wherein the terminal block includes a terminal for electrically connecting two cables;
- and
- an overheating detecting unit configured to detect overheating of the terminal,
- wherein the inverter recognizes an overheated state of the terminal block by shorting the heat sensing wire using an output from the overheat detection unit.
