[0017] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0018] A power output device capable of coping with various emergencies, comprising a container generator set, a high-voltage series output device, a low-voltage parallel output device, an optional second starting device and a master controller CM1, wherein a silent housing 1 is provided on the container generator set; The container generator set, high-voltage series output device, low-voltage parallel output device, and optional second starting device are all connected to the main controller CM1 through a communication line, and the voltage is monitored by the main controller CM1. The main controller CM1 is provided with a control switch that controls the operation of the container generator set, high-voltage series output device, low-voltage parallel output device, and optional second starting device.

[0019] The container generator set, high-voltage series output device, low-voltage parallel output device and optional second starting device are fully monitored through the main controller CM1. When encountering various emergencies, the power output device can adapt to the needs of low-temperature cold areas, areas with high voltage supply requirements at the user end, areas with expanded power supply requirements at the user end, and the need to start the container generator set after the electric starter motor of the diesel engine fails. There is no need to replace the generator set or wait for maintenance according to the requirements of the electrical equipment, thereby ensuring the normal operation of the container generator set, and the power output device can provide stable and reliable power output.

[0020] As a possible implementation manner of the present scheme, preferably, the interior of the container generator set is respectively provided with an internal air temperature sensor 2, a drainage ventilation duct 3, an air inlet electric shutter 4, an air outlet electric shutter 5, a first drainage electric shutter 6, a second drainage electric shutter 7 and a mounting base 9, the first drainage electric shutter 6 and the second drainage electric shutter 7 are respectively located on both sides of the container generator set, the mounting base 9 is respectively installed with a generator 10, an engine 11 and a cooling fan 12, and the outside of the container generator set is provided with an external air temperature sensor 8.

[0021] The air inlet electric shutter 4 and the air outlet electric shutter 5 are both controlled by stepper motors, and the opening angles of the first drainage electric shutter 6 and the second drainage electric shutter 7 are adjusted by the main controller CM1 according to the temperature values ​​detected by the external air temperature sensor 8 and the internal air temperature sensor 2.

[0022] The power output device is placed in a cold area for use. When the external air temperature sensor 8 detects that the ambient temperature is lower than the set value T1, the air inlet electric shutters 4 are fully opened, the air outlet electric shutters 5 are opened at a certain angle, the first drainage electric shutters 6 and the second drainage electric shutters 7 are fully opened, and the airflow comes in from the air inlet electric shutters 4 and passes through the generator 10-engine 11-cooling fan 12-air outlet electric shutters 5-outside the container generator set. Since the air outlet electric shutters 5 are not fully opened, there is a certain resistance, so the airflow flows along the first drainage electric shutters 6 through the drainage ventilation pipe 3 from the second drainage electric shutters 7 to the generator 10, and a new round of circulation is carried out. The heat emitted by the diesel engine inside the container generator set can quickly increase the air temperature inside the container generator set to reach the optimal temperature required for the operation of the container generator set; When the internal air temperature sensor 2 detects that the internal temperature of the container generator set is higher than the set value T2, the air outlet electric shutters 5 are fully opened, the first drainage electric shutters 6 and the second drainage electric shutters 7 are closed, and the air flow comes in from the air inlet electric shutters 4 and passes through the generator 10-engine 11-cooling fan 12-air outlet electric shutters 5-the outside of the container generator set, and the container generator set enters a normal operating state.

[0023] As a possible implementation mode of the present scheme, preferably, the high-voltage series output device comprises a plurality of low-voltage container generator sets arranged in series, and the high-voltage series output device adjusts and maintains the output phase sequence, output voltage value and output frequency value of the plurality of low-voltage container generator sets to be consistent, and issues instructions through the main controller CM1 to realize automatic closing of the circuit breaker, thereby providing an output of a higher voltage value to the outside.

[0024] When the required voltage of the electrical equipment is greater than the output voltage of the container generator set or reaches a multiple of the output voltage of the container generator set, the voltage is increased by connecting multiple low-voltage container generator sets G1, G2, ... in series, that is, by adjusting the output phase sequence of the multiple low-voltage container generator sets G1, G2, ... to be consistent, the output voltage value is consistent (a certain deviation value is allowed), the output frequency value is consistent (a certain deviation value is allowed), and the voltage phase angle is consistent (a certain deviation value is allowed). Under the control of the main controller CM1, the G2-CB... circuit breaker is automatically closed, thereby providing an output of a higher voltage value of G=G1+G2+... to the outside, so that the output voltage of the container generator set meets the voltage demand of the electrical equipment.

[0025] As a possible implementation mode of the present scheme, preferably, the low-voltage parallel output device includes a plurality of low-power container generator sets arranged in parallel. When the load current of the electrical equipment is greater than the output current of the container generator set, the output current power is increased by connecting a plurality of low-power container generator sets in parallel, thereby achieving the purpose of meeting the needs of the electrical equipment.

[0026] The low-voltage parallel output device maintains the consistency of output phase sequence, output voltage value, output frequency value and voltage phase angle of multiple low-voltage container generator sets, and issues instructions through the main controller CM1 to achieve automatic closing of the circuit breaker, thereby providing a higher current output to the outside.

[0027] When the load current of the electrical equipment is greater than the output current of the container generator 10, the output current is increased by connecting multiple low-power container generator sets G1, G2, ... in parallel, that is, by maintaining the output phase sequence of the multiple low-capacity voltage container generator sets G1, G2, ... consistent, the output voltage value is consistent (a certain deviation value is allowed), the output frequency value is consistent (a certain deviation value is allowed), and the voltage phase angle is consistent (a certain deviation value is allowed). Under the control of the main controller CM1, automatic closing of the G2-CB... circuit breaker is achieved, thereby providing an output of a higher current value of IG=IG1+IG2+... to the outside, so that the output current power of the container generator set meets the needs of the electrical equipment.

[0028] As a possible implementation mode of the present scheme, preferably, the alternative second starting device includes a controller submodule CM5, a switch SW1, a switch SW2, a voltage stabilizing filter capacitor C1, a rectifier inverter subunit S and a smoothing current stabilizing reactor L, and the controller submodule CM5 is monitored by the main controller CM1.

[0029] The controller submodule CM5 controls the closing or opening of the switch SW1 and the switch SW2 so that when the electric motor of the diesel engine of the container generator set fails, the container generator set can maintain normal operation.

[0030] When the electric starter motor of the diesel engine of a normal container generator set fails and the diesel engine cannot be started, the alternative second starting device will take effect, and the controller submodule CM5 will invert the DC power of the starting battery pack carried by the diesel engine into three-phase AC power by controlling the switches SW1 and SW2 to be closed. The output three-phase AC power is supplied to the stator winding output terminal S of the generator 10. At this time, the generator 10 changes from the generator 10 state to the motor state, and the rotating rotor R drives the coaxially connected engine 11 flywheel SP to rotate. When the speed of the engine 11 flywheel SP reaches a certain value (the controller submodule CM5 detects the flywheel speed to determine that the diesel engine is successfully started), the controller submodule CM5 sends a command to control the switches SW1 and SW2 to be disconnected, and the container generator set enters a normal operating state.

[0031] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
