JP cabinets are that a kind of electric energy that integrates is distributed, measures, protects, controlled, the comprehensive distribution box of reactive-load compensation.It is existing
JP cabinets are compensated in terms of reactive-load compensation or using common capacitance or intelligent capacitor, are improved by capacitive reactive power
System voltage, and general load be all it is perceptual, can there are following defects：
1st, because the capacitance of capacitor is non-adjustable, once input is exactly whole reactive powers, it is impossible to according to the variation of load
Idle output is automatically adjusted, in light load, was likely to result in benefit, it is also possible to cause system parallel resonance；
2nd, compatilizing mechanism or transformation when, can only realize the adjusting of compensation rate by changing capacitors count, workload is numerous
Weight；
3rd, capacitor service life is short, and usual 3-5 must be replaced；
4th, switching speed is slow, need to generally take more than 2s, it is impossible to action in time；
5th, distribution transformer three-phase load unbalance causes neutral-point displacement, causes phase voltage unbalanced；
In addition, the busbar used in existing JP cabinets is arranged for copper bar or aluminium, the former cost is high, and the latter easily aoxidizes, causes
Electric conductivity declines.

Reactive-load compensation indoor location SVG device, the breaker, SVG device are connected to the busbar, and the SVG device is by leading
Line is connected with low-voltage current mutual inductor, and the low-voltage current mutual inductor is arranged on the busbar of the low pressure basement, for electric current
Sampling.
In a kind of preferred embodiment of comprehensive compensation JP cabinets provided by the utility model, the busbar of the low pressure basement
On be additionally provided with metering units.
In a kind of preferred embodiment of comprehensive compensation JP cabinets provided by the utility model, the metering units use band to take
Three prime minister's net intelligent meters of control.
In a kind of preferred embodiment of comprehensive compensation JP cabinets provided by the utility model, the busbar uses copper aluminium volume
Than the cuprum-cladding-aluminium bus array for 15% or 20%.
Compared with prior art, the advantageous effect of comprehensive compensation JP cabinets provided by the utility model is：
First, the utility model is maintained using real-time tracking of the SVG device realization to voltage fluctuation and flicker and inhibition
Receiving end voltage, strengthening system voltage stability have the function of to balance three phases active power and flexible supplement reactive power, make
Output reactive power is from capacitive to perceptual consecutive variations, it can be achieved that dynamic, continuous, synchroballistic, solve overload, cross and mend and owe
The problem of benefit, improves power factor, reduces line loss, is energy-saving, reducing production cost；
2nd, use the busbar have good electric conductivity and mechanical property, save copper material, reduce production it is mating
Cost.
