Auxiliary power supply connection structure of gasoline engine generator in diesel emergency generator car

Abstract

The invention discloses an auxiliary power supply connection structure of a gasoline engine generator in a diesel emergency generator car, which comprises a section of jumper wire, plugs matched with the inside of an auxiliary power supply bin are adopted on two sides of the jumper wire, and an output interface of the gasoline engine generator is connected with a mains supply input interface of a diesel generator set respectively on two sides of the jumper wire. The auxiliary power supply connection structure has the beneficial effects that the working capacity of the gasoline engine generator is fully utilized, cable take-up and pay-off operation can be achieved without starting the diesel generator set, the working life of the set is prolonged, environmental noise is reduced, and communication of workers is facilitated. Meanwhile, personnel are not influenced by air exhaust and heat dissipation during cable winding and unwinding.

Description

technical field [0001] The invention relates to the technical field of diesel emergency generator vehicles, in particular to a gasoline generator auxiliary power supply connection structure used in diesel emergency generator vehicles. Background technique [0002] When a normal emergency diesel generator vehicle is deployed on site, it needs to supply power to the cable winch in the vehicle to release the cable. In the original vehicle wiring mode, the power supply needs to be provided by the site with a three-phase AC power supply, or start the diesel generator set in the vehicle for self-power supply for lighting, wiring shafts, online fuel pumps and other auxiliary electrical equipment in the vehicle. When used in conjunction with the flywheel energy storage unit, it is also necessary to start the diesel unit, unwind, and connect the cables before supplying power to the flywheel energy storage unit and performing the unwinding operation of the energy storage unit. There ...

AI Technical Summary

Problems solved by technology

[0003] ①Due to site constraints, most of the work scenes cannot provide external AC power supply, and can only be self-powered by starting the diesel generator set for retracting and releasing cables and providing lighting

[0004] ②Due to the large capacity of the unit, its design working condition is on-load operation, and long-term no-load is not allowed

During on-site deployment, the power consumption of electrical equipment such as winches is negligible, resulting in extremely low unit load rate and affecting the life of the unit

And due to the lack of working pressure in the cylinder when it is empty, oil splashes on the exhaust cylinder head and pollutes the cabin

[0005] ③When working in winter, due to the low temperature, the water jacket needs to be preheated in advance before the diesel unit starts and realizes self-power supply. The heating time is about 2-3 hours. The cable retraction work can only be carried out after the unit has the starting conditions. , affecting work efficiency

[0006] ④ When the battery of the unit loses power due to multiple starts, low-temperature starts in winter, etc., it can only wait for rescue in place, without self-rescue ability, which affects the reliability of power supply guarantee work

[0007] ⑤ When deploying in cold and hot weather, because the cable warehouse is located behind the exhaust outlet of the unit, when the unit is started, the exhaust air will blow directly to the workers; and the unit is noisy, it is difficult to communicate during work, and the operating environment is relatively harsh, reducing work efficiency

[0008] ⑥When working with the flywheel energy storage unit, it is necessary to release and connect the cables of the generator set first, then connect the circuit breaker to supply power to the flywheel unit, and then start the cable winch of the flywheel unit for unloading work. The two units cannot realize simultaneous Retracting and unwinding cables increases the deployment time, and there is also the problem of unit no-load loss

[0009] ⑦The gasoline engine is only used for lighting and sockets, the capacity is wasteful, and it cannot supply power to other electrical equipment in the car, and cannot fully exert its auxiliary power supply function
