    摘要： An emergency stop system for a hybrid excavator is provided, which includes an emergency switch and an emergency stop unit. In a normal operation state, a power supply that is applied from a power supply unit is provided to a hybrid controller and an engine controller, while when the emergency switch is pressed, the input power supply is intercepted to effectively stop the operation of the hybrid system in the case where equipment abnormality or an emergency situation occurs. Also, when the emergency switch is pressed, the power supply is applied to an emergency alarm unit and an energy discharge unit to notify an operator and neighboring persons of the equipment abnormality and emergency situation occurrence, and a hybrid power source vanishes completely.

    摘要： A discharge system of a stored energy for a construction machine is provided, which includes the energy storage, an electric discharge device discharging energy stored in the energy storage, and an energy cooling portion increasing the heat dissipation capacity of the electric discharge device by cooling heat generated in the electric discharged device for a time when the energy stored in the energy storage is discharged to the electric discharge device. Since the heat generated in the electric discharge device is cooled by a cooling device while the energy stored in the energy storage is discharged to the electric discharge device, the heat dissipation capacity of the electric discharge device is increased to shorten the discharge time. Also, the operation period of the cooling device is controlled in proportion to the residual voltage of the energy storage, and thus the cooling efficiency is maximized.
