When locomotive was in the full diesel traction working condition, locomotive was in running state, by diesel engine power was provided separately, and battery pack is not devoted oneself to work.At this moment, the locomotive control switch is in closure state, battery pack drops into switch and is in off-state, and the handle level is in non-0 grade, and promptly the handle level is in the 1-16 shelves.
When locomotive was in double dynamical traction working condition, locomotive was in running state, by diesel engine power was provided preferentially.At this moment, the locomotive control switch be in closure state, battery pack drop into switch be in mix a position state, the energy recovery switch is in off-state, the handle level is in non-0 grade, promptly the handle level is in the 1-16 shelves.
Locomotive can also provide the traction required drive by battery pack separately.The pattern of power is provided by battery pack separately, mainly is applicable to the fast situation that finishes of short distance, underload or locomotive work.Owing to receive the restriction of battery pack residual capacity, can select whether to launch the pattern that independent battery pack provides power by the operation driver.When adopting pure storage battery to draw, locomotive does not almost have noise and non-exhaust emission, can reach the effect of environmental protection.When locomotive is in pure battery pack traction working condition; Diesel engine is in stopped status; By battery pack the locomotive operation required drive is provided; At this moment; The locomotive control switch is in closure state, battery pack drops into switch and is in pure battery position state; The handle level is in non-0 grade, and promptly the handle level is in the 1-16 position.
From the above, in embodiment provided by the invention, dual powered locomotive can provide the traction required drive separately by diesel engine or battery pack, also can the traction required drive be provided jointly by diesel engine and battery pack.And the energy of said battery pack can obtain by external source is additional, also can be obtained to its charging by diesel engine.
In the dual powered locomotive control method that the embodiment of the invention provides, can also control diesel engine to battery charging.At this moment, locomotive is in pure battery charging operating mode.Concrete, by diesel engine power being provided, the locomotive control switch is in off-state, battery pack drops into switch and is in pure battery position state, and the handle level is in 0 grade, and diesel engine is to battery charging.
Certainly, for dual powered locomotive, except that above-mentioned three kinds of traction working conditions and battery charging operating mode, damped condition also is one of important operating mode of locomotive operation.In embodiment provided by the invention, can also comprise control to damped condition.When locomotive is in damped condition, by diesel engine power is provided, at this moment, the locomotive control switch be in closure state, battery pack drop into switch be in mix a position state, the energy recovery switch is in closure state, the handle level is in non-0 grade (being the 1-16 position).Because the dual powered locomotive control method that the embodiment of the invention provides can realize the recovery of braking energy, therefore when locomotive was in braking mode, the energy recovery switch was closed.
When locomotive was in idle conditions, diesel engine, battery pack were not devoted oneself to work, and at this moment, the locomotive control switch breaks off, and battery pack drops into switch and breaks off, and the energy recovery switch breaks off.
Corresponding relation between the various operating modes of above-mentioned locomotive and the switching value of said locomotive, the handle level information can be as shown in table 1.Information such as locomotive switching value that thus, can be through collecting, handle level are carried out the locomotive operating mode and are judged.
