Description
Technical Field
The invention relates to the technical field of diesel emergency power generation vehicles, in particular to an auxiliary power supply connection structure for a gasoline engine generator in a diesel emergency power generation vehicle.
Background
When the normal emergency diesel generator car is used for field deployment operation, a cable winch in the car needs to be powered to discharge a cable. In the original vehicle wiring mode, the power supply needs to provide a three-phase alternating current power supply from a field or start a diesel generating set in the vehicle to carry out self-power supply so as to be used for auxiliary electric equipment in the vehicle, such as lighting, a wire connecting shaft, an online oil filling pump and the like. When the flywheel energy storage unit is used in a combined mode, the flywheel energy storage unit can be powered up and the paying-off operation of the flywheel energy storage unit can be executed after the diesel engine unit is started, paid-off and connected with a cable. A5 kW small gasoline generator is additionally arranged in the vehicle, and the original vehicle design is only used for illumination and a single-phase socket in a carriage.
Firstly, due to the limitation of places, most working scenes cannot provide an external alternating current power supply, and the self-power supply can be realized only by starting a diesel generator set so as to receive and release cables and provide illumination.
Secondly, because the unit has larger capacity, the unit is designed to operate under the load condition, and no load is allowed for a long time. In the field deployment work, the power consumption of electric equipment such as a winch is extremely small and negligible, so that the load rate of a unit is extremely low, and the service life of the unit is influenced. And the working pressure in the cylinder is insufficient during no-load, so that oil splashing at the cylinder cover is caused, and the cabin is polluted.
When the diesel engine set works in winter, due to low temperature, the water jacket needs to be preheated in advance before the diesel engine set is started and self-powered, the heating time is about 2-3 hours, and the cable winding and unwinding work can only be carried out after the diesel engine set has the starting condition, so that the working efficiency is influenced.
And fourthly, when the storage battery of the unit is insufficient due to multiple starting, low-temperature starting in winter and the like, the unit can only wait for rescue in situ, does not have self-rescue capability, and influences the reliability of power supply guarantee work.
When the cable bin is deployed in cold and hot days, after the cable bin is positioned at an air outlet of the unit and the unit is started, the cable bin causes direct blowing of air exhaust; and the unit work is noisy, the communication is difficult during the work, the working environment is relatively bad, and the working efficiency is reduced.
When the flywheel energy storage unit is matched with the flywheel energy storage unit to work, a cable of the generator set needs to be firstly released and connected, then the breaker is closed to supply power to the flywheel unit, the cable winch of the flywheel unit can be started to release the cable, the two units cannot simultaneously release and release the cable, the deployment time is prolonged, and the problem of no-load loss of the units is also solved.
And the gasoline engine is only used for lighting and a socket, so that the capacity is wasted, other electric equipment in the vehicle cannot be supplied with power, and the auxiliary power supply function of the gasoline engine cannot be fully exerted.
An input circuit of a dual power supply (mains supply and a diesel engine) in the existing power generation car is shown in fig. 1.
1L1 ~ 1N is the commercial power input end, 2L1 ~ 2N is the diesel engine input end. QF6 and QF7 are air switches, and KM1 and KM2 are relays. H300-H303 lead to auxiliary electric equipment in the vehicle.
The output circuit of the gasoline engine generator is shown in figure 2.
QF8 and QF9 are air switches, XS10 is an output port located in the auxiliary power wiring compartment, and QF10 is a rotary switch. H300-H303 are derived from dual power outputs, H340-H342 output to lighting and sockets. After the small oil engine is connected, the lighting and socket power supply can be selected to be output from the small oil engine or the diesel engine set by rotating the QF 10.
The load circuit supplied by the gasoline engine generator is shown in figure 3. The EL 1-EL 4 are indoor illuminating lamps, the QF17 is a residual current protector, and the XS13 and the XS14 are seats in a carriage. Fig. 4 shows a circuit of an auxiliary electric device in a vehicle.
Disclosure of Invention
Based on the purpose, the invention provides an auxiliary power supply connection structure of a gasoline engine generator in a diesel emergency power generation vehicle.
In order to achieve the purpose of the invention, the invention provides an auxiliary power supply connection structure of a gasoline generator in a diesel emergency power generation car, which comprises a section of jumper wire, wherein plugs matched with the auxiliary power supply bin are adopted at two sides of the jumper wire, and the output interface of the gasoline generator is respectively connected with the commercial power input interface of a diesel generator set at two sides of the jumper wire.
When the energy storage device is used with a flywheel energy storage unit, the output of the gasoline generator is divided into two parts by utilizing the platform with the wiring spool, wherein one part realizes self power supply of the diesel unit through the jumper wire, and the other part extends to the commercial power receiving end of the flywheel unit outside the automobile to provide alternating current auxiliary power supply for the flywheel energy storage unit.
Compared with the prior art, the invention has the advantages that,
the working capacity of the gasoline engine generator is fully utilized, the cable winding and unwinding operation can be realized without starting the diesel generator set, the working life of the unit is prolonged, the environmental noise is reduced, and the communication of workers is facilitated. Meanwhile, personnel do not need to be affected by air exhaust and heat dissipation when the cable is wound and unwound.
And secondly, during operation in winter, the influence of the preheating time of the diesel engine unit is avoided. The small oil engine can be started at any temperature to realize power supply, and can heat the water jacket of the unit while cable laying, so that the deployment time is shortened, and the working efficiency is improved.
And thirdly, when the storage battery of the unit is in power shortage, the gasoline generator is started to supply power, and then the storage battery can be supplemented with power through the charging motor in the vehicle to realize self rescue. The electricity supplementing process can be synchronously performed with the cable winding and unwinding operation, but because the capacity of a storage battery of the unit is large, the power supply capacity of the gasoline generator is limited, the single starting requirement can be met only by charging for 2 hours, and the electricity is required to be recharged if the starting fails. The other self-rescue mode is that a storage battery of the unit is connected with a storage battery of the chassis in parallel through a storage battery jumper wire, and the mode of taking power is the same as that of taking power when a common civil vehicle is rescued. This method requires the fabrication of additional high current (over 1000A short time) wires and clamps, and will not be discussed herein.
When the gasoline engine is used with the flywheel energy storage unit, the output of the gasoline engine generator is prolonged to the commercial power input end of the flywheel energy storage unit through the wire shaft, so that the two units can simultaneously perform cable winding and unwinding operation, the working efficiency is improved, and the deployment time is shortened. Meanwhile, when the storage battery of the flywheel energy storage unit is in power shortage, the flywheel energy storage unit can be rapidly charged in the mode, and rapid car rescue is achieved.
