Description
Technical field
The utility model relates to a kind of intelligent network distribution energy-saving control system.
Background technology
Intelligent network distribution is one of key link of intelligent grid.
Intelligent network distribution by making power distribution network dominate from traditional supplier, unidirectional power supply, the basic operation mode relying on labor management is to user's participations, trend two-way flow, the transformation of supermatic direction.Along with the progress that China DG builds, more and more significantly economic benefit and social benefit will be produced.
TT mode electric power system refers to directly grounded for the metal shell of electric equipment protection system, is called protective earthing system, also claims TT system.First symbol T represents the direct ground connection of neutral point in electric power system; Second symbol T represents that the metal conduction portions that load equipment exposes not connect with electrified body directly connects with the earth, and how ground connection has nothing to do with system.
Summary of the invention
The purpose of this utility model is to provide a kind of intelligent network distribution energy-saving control system.
The utility model realizes by the following technical solutions: a kind of intelligent network distribution energy-saving control system, is characterized in that: comprise the first circuit breaker, the second circuit breaker, the 3rd circuit breaker, the first residual current operated protective device, the second residual current operated protective device, the first earthing isolator, the second earthing isolator, surge protector, mend capacitor and point benefit capacitor altogether; Described first circuit breaker one end is connected on bus, and the other end is connected on the neutral line; Described first residual current operated protective device is connected with the first circuit breaker; The described first earthing isolator one termination first circuit breaker other end, described another terminating load of first earthing isolator; Described second circuit breaker one end is connected on bus, and the other end is connected on the neutral line; Described second residual current operated protective device is connected with the second circuit breaker; The described second earthing isolator one termination second circuit breaker other end, described another terminating load of second earthing isolator; Described surge protector first end connects bus through a fuse, the second termination neutral line, the 3rd end ground connection; The described capacitor one of benefit altogether termination bus, another termination divides benefit capacitor.
In the utility model one embodiment, also comprise the first current transformer be connected with the first earthing isolator other end and the second current transformer be connected with the second earthing isolator other end.
Preferably, the described first to the 3rd circuit breaker is autoreclose breaker.
Compared with prior art, the utility model adopts TT mode electric power system to draw up high-voltage line and low-voltage line connects or between distribution transforming high-low pressure winding, during insulation breakdown, low voltage electric network occurs overvoltage; Certain leakage ability is had to the Lightning Over-voltage of low voltage electric network; Compared with earth-free with low-voltage electrical apparatus shell, when electrical equipment touches shell accident, the voltage to earth of shell can be reduced, thus can alleviate the personal electric shock extent of injury; Because earth current during single-phase earthing is larger, protective device (earth leakage protective device) action message can be made, excise fault in time; Increase residual current operated protective device, when residual current meets or exceeds set-point, the earthing isolator of energy automatic shutoff circuit, ensures Electrical Safety; Reactive power compensation part comprises common benefit capacitor and point benefit capacitor, mends the first switching of capacitor altogether, thus reaches more reasonable, more economical.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the utility model one embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
See Fig. 1, the utility model provides a kind of intelligent network distribution energy-saving control system.This system comprises the first circuit breaker 1QF, the second circuit breaker 2QF, the 3rd circuit breaker 3QF, the first residual current operated protective device, the second residual current operated protective device, the first earthing isolator 1QS, the second earthing isolator 2QS, surge protector, mends capacitor and point benefit capacitor altogether; Described first circuit breaker 1QF mono-end is connected on bus, and the other end is connected on neutral line N; Described first residual current operated protective device is connected with the first circuit breaker 1QF; The described first earthing isolator 1QS mono-termination first circuit breaker 1QF other end, described first another terminating load of earthing isolator 1QS; Described second circuit breaker 2QF mono-end is connected on bus, and the other end is connected on neutral line N; Described second residual current operated protective device is connected with the second circuit breaker 2QF; The described second earthing isolator one termination second circuit breaker 2QF other end, described second another terminating load of earthing isolator 2QS; Described surge protector F first end connects bus through a fuse FU, the second termination neutral line N, the 3rd end ground connection; The described capacitor one of benefit altogether termination bus, another termination divides benefit capacitor.
When residual current meets or exceeds set-point, the earthing isolator of energy automatic shutoff circuit, ensures Electrical Safety.Mend capacitor altogether with point benefit capacitor for this system provides reactive power compensation.When capacitor switching, be first putting into operation of common benefit, put into operation after point benefit, because accomplish three-phase load balance as far as possible during sharing of load, concerning a transformer, can not only with the load of a certain phase, therefore, major part should be common benefit, fraction is a point benefit, such Scheme of Reactive Power Compensation is more reasonable, more economical (point benefit is more expensive than mending altogether), thus reaches energy-conservation effect.
In the utility model one embodiment, also comprise the first current transformer LH1 be connected with the first earthing isolator other end and the second current transformer LH2 be connected with the second earthing isolator other end.Current transformer detects the output current of earthing isolator.
Circuit breaker in the utility model embodiment is electric operating and can automatic reclosing, and when circuit breaks down, after relaying protection makes circuit breaker trip, auto recloser makes circuit breaker again close after short time interval.In most cases, line fault (as thunderbolt, windburn etc.) is temporary, after circuit breaker trip, the insulation property (insulator and air gap) of circuit can be restored, and again overlapping can be successful, this provides for improved the reliability of power system power supply.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
