The utility model discloses a diesel generator parallel machine steps up the succeeding crop by step up transformer and is high -pressure standby power system, has solved because of plan or proruption have a power failure to the influence of bacterium oxygen suppliment, has effectively solved stand -by power supply's problem.
Description
Technical field
This utility model relates to electric power system field, and a kind of diesel generating set is as standby height
The electric power system of voltage source.
Background technology
Biological oxidation gold extraction factory technological requirement uninterrupted power supply, it is impossible to power-off condition occurs.In some of China
An area only road high voltage power supply, it is achieved not one for one for dual power supply.Blower fan for antibacterial oxygen supply is
The GM35 high pressure positive blower that Shen Gu company produces, Rated motor voltage 10KV.That electromotor sends is 0.4KV
Low-voltage AC, it is impossible to start 10KV high pressure positive blower, electromotor therefore can not be used as stand-by power supply.
Utility model content
For above-mentioned weak point present in prior art, the technical problems to be solved in the utility model is to carry
Supply a kind of diesel generating set as the electric power system of standby high voltage power supply.
This utility model be the technical scheme is that a kind of diesel generating set conduct for achieving the above object
The electric power system of standby high voltage power supply, including:
Some diesel-driven generators, every diesel-driven generator sends low-voltage AC, and machine is arranged, and output is also
Low-voltage AC after machine；
Booster transformer, the low-voltage AC after the described also machine of input, by the low-voltage AC transformation after also machine
To required high pressure, export described High Level AC Voltage；
High-voltage switch gear, one end connects the outfan of booster transformer, and the other end connects chopper；
Chopper, one end connects high-voltage switch gear, and the other end is for connecting distribution bus to be powered.
The power of the output after described some diesel-driven generators machine and described booster transformer is mutually
Join.
This utility model has the following advantages and beneficial effect:
1. as high pressure stand-by power supply after this utility model uses diesel-driven generator machine to be boosted by booster transformer
System, solves the impact on antibacterial oxygen supply because of plan or burst power failure, efficiently solves asking of stand-by power supply
Topic.
The most simple, convenient, safety.
Accompanying drawing explanation
Fig. 1 is overall construction drawing of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment.
Three 640KW diesel-driven generators send 0.4KV alternating current, by 0.4KV electricity after the most also machine
Power delivers to 2000KVA/10KV/0.4KV booster transformer, booster transformer export 10KV high-tension electricity
Being switched by high-voltage switch gear, to electric substation of company, high-pressure system is powered, and constitutes 10KV CAPACITY IN ELECTRICITY power supply system
System (as shown in Figure 1), after starting high pressure positive blower, dump energy supply workshop low-voltage equipment maintains and normally produces.
The operation order that use this utility model carries out transmission or not disconnecting link is as follows:
1, when grid power blackout, first disconnect former electric power system 01D always by cabinet, by stop button, make to break
Road device QF disconnects, and then opens 01D high-voltage board face door, handcart type breaker is pulled open open position,
There is an obvious cut-off point, and hang up " someone operate, No switching on " nameplate.
2, close from the XGN1 high-tension switch cabinet 101# disconnecting link of booster transformer 10KV side, and determine
10KV voltage is normal, then presses XGN2 high-voltage board 102# breaker closing button, makes closing of power circuit breaker.
3, by former electric power system standby high-voltage cabinet panel switch knob, connect chopper and 10KV power supply is supplied to
On distribution bus, complete to power to electric substation's high-pressure system.
4, check 10KV high tension loop comprehensively, after confirming normally, 10KV electric power point loop in factory allotted,
Start high pressure positive blower to return to normal production.
When system recovery normal power supply needs to stop generator powered, grid switching operation is contrary with power transmission order,
I.e.: first by former electric power system reserve tank stop button, disconnect 10KV power supply, by XGN2 high-voltage board
102# vacuum switch cabinet opening button cut-off breaker, disconnects XGN1 high-voltage board 101# disconnecting link, takes and hang over
Always by cabinet 01D nameplate cashier's office in a shop, after pushing hands formula switch cubicle, close cabinet door and press always by cabinet switch knob, make
Circuit breaker Q F combined floodgate completion system normal power supply.
The technical essential of aforesaid operations is:
1, when original system 01D is always powered by cabinet, A mechanical electromagnetic control chain generator high_voltage isolation is opened
Closing cabinet XGN1 disconnecting link can not close a floodgate, B electromagnetic chain controls generator breaker XGN2 and can not close a floodgate.
2, when electric set electric supply, XGN1, XGN2 control 01D always can not be closed a floodgate by cabinet.
3, handcart must be pulled out at open position when original system 01D is always had a power failure by cabinet, have obvious cut-off point.
