Abstract
The invention belongs to electricity power field power plant diesel-driven generator backup power supply automatic starting device.Technical solution：It ensures public security B sections including A sections of accident security personnel and accident, by A sections of busbares of 380V through A sections of operating switches power supplies of accident security personnel when A sections of accident security personnel work normally, B sections of busbares of 380V ensure public security A sections of backup circuit breakers as accident A sections of backup power supplies of security personnel through accident；By B sections of busbares of 380V through B sections of operating switches power supplies of accident security personnel when accident B sections of normal works of security personnel, A sections of busbares of 380V ensure public security B sections of backup circuit breakers as accident B sections of backup power supplies of security personnel through accident；Advantageous effect：By applying this diesel-driven generator self-starting device, it can effectively realize under power cut of whole factory accident, diesel-driven generator is reliably the power supply of engine health stoppage in transit capital equipment normal operation, and after having accident security personnel's section busbar dead electricity, diesel-driven generator will not start automatically.
Description
Technical field
The invention belongs to electricity power field, is related to power plant's field accident and full factory is caused to have a power failure suddenly, and diesel-driven generator is made
Timely automated it can start and with physical burden for backup power supply, it is ensured that engine health is stopped transport, and ensures power plant capital equipment not
The power plant's diesel-driven generator backup power supply automatic starting device damaged.
Background technology
Backup power equipment of the diesel-driven generator as accident security personnel section in factory, diesel oil are configured in the factory of electric system at present
Generator control system monitors accident security personnel's section work or spare a certain switch closes position and this section of busbar under-voltage replay contact
After acting feedback signal, start diesel-driven generator automatically, and controls diesel-driven generator gate out switch, accident security personnel's section bavin energy source
It closes a floodgate to switch, the security personnel's section work of control accident and backup circuit breaker separating brake are selectively sent to accident security personnel section in factory, are this Duan Chong
Load is wanted to provide reliable source of power, emphasis is guarantor's accident security personnel's section load normal operation, is ignored in power cut of whole factory,
The safety for being unable to ensure generator is stopped transport, and main equipment easily causes the possibility of damage.
Invention content
To solve the problems, such as this, the purpose that power cut of whole factory power plant capital equipment does not damage is reduced, design has developed diesel oil hair
A kind of power plant's diesel-driven generator backup power supply that motor just starts automatically in two accidents security personnel's equal dead electricity of section busbar from
Dynamic starter can effectively realize under power cut of whole factory accident that diesel-driven generator is reliably that generator is pacified by the application of the device
Full cut-off transports the power supply of capital equipment normal operation.
Technical solution：It ensures public security A sections including accident and ensures public security B sections with accident, reliable electricity is provided for Important Auxiliary equipment equipment in power plant
Source, accident are ensured public security A sections when working normally by A sections of busbares of 380V through A sections of operating switches power supplies of accident security personnel, B sections of busbares of 380V
A sections of backup circuit breakers are ensured public security as accident A sections of backup power supplies of security personnel through accident；Accident is ensured public security B section when working normally by B sections of 380V
Busbar ensures public security B sections of backup circuit breakers as accident security personnel B through B sections of operating switches power supplies of accident security personnel, A sections of busbares of 380V through accident
Section backup power supply；Diesel-driven generator outlet power cable connection bavin hair gate out switch is suitable for reading, and bavin sends out mouth under gate out switch and connects bavin
It is suitable for reading to be sent to security personnel's section switch, bavin be sent to security personnel's lower mouth of section switch and A section bavins send switch, B a section bavin send switch it is suitable for reading arranged side by side
Connection, A section bavins, which send switch, B a section bavin and send the lower mouth of switch, is separately connected reconnection accident security personnel A sections, B after A sections of PT, B sections of PT
Section, A sections of PT, B sections of PT are respectively accident security personnel A sections, B sections of voltage transformers, for monitoring busbar voltage.
Advantageous effect：By applying this diesel-driven generator self-starting device, can effectively realize under power cut of whole factory accident, diesel oil
Generator is reliably that engine health stoppage in transit capital equipment normal operation is powered, and working as has accident security personnel's section busbar dead electricity
Afterwards, diesel-driven generator will not start automatically.
Description of the drawings：
Attached drawing 1 is the connection relationship diagram of the present embodiment.
Specific implementation mode：
Referring to Fig.1, this implementation column includes mainly accident security personnel A sections 8 and accident security personnel B sections 13, is Important Auxiliary equipment in power plant
Equipment provides reliable source of power, and accident is ensured public security A sections and supplied through accident A sections of operating switches 7 of security personnel by A sections of busbares of 380V when working normally
Electricity, B sections of busbares of 380V ensure public security A sections of backup circuit breakers 6 as accident A sections of backup power supplies of security personnel through accident；Accident ensures public security B sections normally
It is powered through accident B sections of operating switches 11 of security personnel by B sections of busbares of 380V when work, A sections of busbares of 380V are standby through B sections of accident security personnel
Use switch 12 as accident B sections of backup power supplies of security personnel；The outlet of diesel-driven generator 1 power cable connection bavin hair gate out switch 2 is suitable for reading,
Bavin hair gate out switch 2 time mouths connection bavins are sent to that security personnel's section switch 3 is suitable for reading, and bavin is sent to 3 times mouths of section switch of ensuring public security and is sent out with A sections of bavins
It closes 4, B sections of bavins and sends the connection arranged side by side suitable for reading of switch 5, A sections of bavins, which send switch 4, B a section bavin and send 5 times mouths of switch, is separately connected A sections of PT
9, accident security personnel A sections 8, B sections 13 are reconnected after B sections of PT 10, A sections of PT 9, B section PT 10 are respectively accident security personnel A sections 8, B sections 13
Voltage transformer, for monitoring busbar voltage.
Diesel-driven generator control system monitors the work of accident security personnel's two busbares of section or a spare only switch is closing position
It is automatic to start diesel-driven generator 1 and after two busbar under-voltage replay contacts have action feedback signal, and close diesel oil hair
Motor gate out switch and security personnel's section diesel-driven generator are switched and are switched respectively to two busbar diesel-driven generators, separate two
The work of busbar and backup circuit breaker.
