The invention provides a conveying device. The conveying device comprises: a bottom platform, the bottom platform comprising a horizontal guide rail; a hoisting device, the hoisting device being arranged on the bottom platform and capable of moving along the horizontal guide rail of the bottom platform, the hoisting device comprising a base, a hoisting beam and a hoisting mechanism between the base and the hoisting beam, and the hoisting mechanism enabling the hoisting beam to ascend or descend relative to the base, wherein both the base and the hoisting beam extend in a direction parallel to the horizontal guide rail of the bottom platform; and a driving device, the driving device being capable of driving the hoisting device to move along the horizontal guide rail.

Conveying device and battery swap station

Battery swapping platform

A trip apparatus for a circuit interruption device that comprises a coil operatively connectable to a circuit interruption device. The coil is configured to selectively operate the circuit interruption device to interrupt when a current flowing through the circuit interruption device exceeds a threshold. The trip apparatus also includes a current measuring device configured to selectively measure a coil current flowing through the coil to determine a measured coil current signal. In addition, the trip apparatus includes a monitoring device configured to determine the derivative of the measured coil current signal and to perform a correlation of the derivative of the measured coil current signal and a reference derivative of a reference coil current signal to determine a correlation output. The monitoring device is further configured to compare the correlation output with a reference correlation threshold to determine whether an operating condition of the coil is normal or abnormal.
