To achieve these goals, the utility model adopts following technical scheme:
A kind of self-starting power supply device, comprise two road three phase mains respectively behind the first via switch cubicle and the second way switch cabinet again through the middle first contact cabinet, connect busbar by incoming line cabinet, by being connected to cooling blower behind blower fan isolating switch and the blower fan on-load switch, generator is connected to cooling blower by generator isolating switch and generator load switch through the second contact cabinet after connecting busbar more again;
Described electric supply installation also comprises relay, B, the C two-phase of two ports of relay in cable connection incoming line cabinet, two contacts of relay are connected on number one and No. second terminal of generator terminals, by the switching of alternate two contacts of voltage control relay of the B in the incoming line cabinet, C two, thereby starter-generator is outwards exported electric energy.
Be connected to a signal lamp in the described generator load switch, between the B of signal lamp access generator output, C two-phase power supply.
Described relay is a under-voltage replay.
The utility model is gone into two ports of under-voltage replay indirectly by the two-phase power supply in the incoming line cabinet of three phase mains commonly used, two contacts of relay are connected on number one and No. second terminal of generator terminals, by the switching of two alternate two contacts of supply voltage control relay in the incoming line cabinet, outwards export electric energy thereby start diesel engine generator.After two road power interruptions commonly used, device of the present utility model can make diesel engine generator rise to rated speed from the zero-speed self-starting immediately and externally power; If recovering to send electricity, this device can make diesel engine reduce to zero-speed automatically, external power stops power supply during diesel generator self-starting power supply.
The utility model is simple in structure, and is safe in utilization, cheap reaching under the same Switching power purpose, saved a large amount of expenses.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 3, a kind of self-starting power supply device, comprise two road three phase mains respectively behind the first via switch cubicle 1 and the second way switch cabinet 2 again through the centre first the contact cabinet 3, connect busbar 7 by incoming line cabinet 4, by being connected to cooling blower 8 behind blower fan isolating switch 5 and the blower fan on-load switch 6, diesel engine generator 9 is connected to cooling blower 8 by generator isolating switch 10 and generator load switch 11 through the second contact cabinet 12 after connecting busbar 13 more again;
Described electric supply installation also comprises under-voltage replay 14, B, the C two-phase of two ports of relay 14 in cable connection incoming line cabinet 4, two contacts of relay 14 are connected on number one and No. second terminal of generator 9 terminals, by the switching of alternate 14 2 contacts of voltage control relay of the B in the incoming line cabinet 4, C two, thereby start outwards output electric energy of diesel engine generator 9.
Be connected to a signal lamp in the described generator load switch 11, between the B of these signal lamp access generator 9 outputs, C two-phase power supply, in order to the operating state of expression generator 9.
The model of described under-voltage replay is DJ-152A, rated voltage 380V-400V, and its coil motion voltage is divided into 80,100,120,140,160 5 grades.Selected one grade of 80V in the present embodiment.
When two tunnel external three phase mains can not be powered simultaneously, self-starting power supply device of the present utility model can outwards be exported electric energy by timely starter-generator, thereby guaranteed the cooling blower normal power supply.
The operation logic of the utility model self-starting power supply device is:
Referring to Fig. 3, Fig. 4, if incoming line cabinet 4 normal power supplies of three phase mains commonly used, its B, C two-phase are 380V, this moment, under-voltage replay 14 coils were failure to actuate, it carries normally opened contact and is in often to open and remains unchanged, and No. the 1st, generator 9 and No. 2 terminal disconnect, and generator is not worked.Reduce to 80V as B, C two-phase in the incoming line cabinet 4 of three phase mains commonly used by 380V, this moment under-voltage replay 14 coil motion, its carry normally opened contact often open become normally closed.
When running into commonly used three phase mains normal power supply fault, be that incoming line cabinet 4 is jumped, the B of incoming line cabinet 4, C two-phase no-voltage, this moment under-voltage replay 14 coil motion, it carries normally opened contact and becomes normally off by normally open, No. the 1st, generator and No. 2 terminal become conducting by disconnection, and this moment, generator 9 startups dropped into power supply.The B, C two-phase voltage that take from the on-load switch 11 of diesel engine generator 9 current supply circuits be not by having to having, and is installed in B, C two alternate signal lamps are lighted, and show that generator 9 has been in generating state.
Recover as three phase mains commonly used; be that incoming line cabinet 4 recovers normal; under-voltage replay 14 was also followed and was recovered initial shape this moment; its from contact-carrying by the normally closed normally open that transfers to; No. the 1st, generator and No. 2 terminal are also opened by normally closed often transferring to, and generator 9 is shut down, the out-put supply excision of generator; signal lamp extinguishes, and the incoming line cabinet 4 of power supply commonly used drops into power supply.
Self-starting power supply device of the present utility model be based on power supply commonly used in power supply process for a certain reason supply voltage reduce too much or temporary transient the power failure, voltage reaches predetermined value in this moment power circuit commonly used, then the self-starting generator; When supply voltage commonly used recovers just often, automatic stop generator then.
It below only is preferred embodiment of the present utility model; be not to be used to limit protection range of the present utility model; therefore, all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
