Description
Technical field
This device relates to power product technical field, comprehensively adjusts in particular to a kind of distribution transformer voltage power-less
Engagement positions.
Background technology
Along with expanding economy and the extensive application of high technology equipment, the requirement to the quality of power supply is more and more higher, voltage
Fluctuation and the change of reactive power directly affect power supply quality, and the power supply being related to power distribution network is stable, economical operation.Reactive-load compensation
Reasonable disposition and the optimizing regulation of voltage be to ensure that power distribution network power supply quality and drop low-loss important means.
Distribution transformer voltage power-less structure adjusting device is that one can adjust distribution transformer in the case of on-load
Device output voltage, controls the switching of reactive power compensator capacitor, balance low-voltage circuit and Reactive Power in Distributing Transformer simultaneously
Voltage power-less structure adjusting device.At present, distribution transformer is all non-excitation pressure adjustment mode, it is impossible to along with distribution transformer supplies
The change of piezoelectric voltage realizes automatic loaded voltage regulation, more can not realize voltage, idle structure adjusting, causes the low pressure of power distribution network to supply
Piezoelectric voltage qualification rate is low, loss is serious.When distribution transformer supply voltage height, reactive power deficiency, due to distribution transformer
Can not automatic loaded voltage regulation, so reactive power compensator cannot put into capacitor and carry out reactive-load compensation, cause distribution transformer to supply
Piezoelectric voltage is constantly in the state that voltage is high, and reactive power is transmitted in supply line always, and loss increases.Work as distribution transformer
When supply voltage is low, reactive power is not enough, reactive power compensator puts into capacitor and carries out reactive-load compensation, joins after reactive power equilibrium
The supply voltage of piezoelectric transformer may be still below the lower limit of voltage acceptability limit, owing to distribution transformer can not have load to adjust automatically
Pressure, causes the supply voltage of distribution transformer to be constantly in the state that voltage is low, affects supply voltage quality.Therefore only has distribution
Transformator realizes automatic loaded voltage regulation, and realizes voltage, idle structure adjusting with reactive power compensator, and guarantee is powered electricity
Qualified and the reactive power equilibrium of pressure.
Summary of the invention
It is an object of the invention to provide a kind of distribution transformer voltage power-less structure adjusting device, to solve prior art
In, to distribution transformer can not the distribution transformer that causes of automatic loaded voltage regulation can not structure adjusting electricity with reactive power compensator
