Abstract
The invention discloses a reactive compensation device for a power distribution transformer. The device comprises a capacitor assembly, a controller, a current transformer and a voltage detection point. According to the device, the problem that in the prior art, the power distribution transformer is insufficient in reactive power and high in loss is solved, the reactive balance of the power distribution transformer is realized, and the reactive loss of the power distribution transformer is reduced.
Description
Technical field
This device is related to power product technical field, in particular to a kind of distribution transformer reactive power compensator.
Background technology
Distribution transformer is afterbody transformer in electrical network, and electric energy is supplied directly to user, and user can provide for oneself simultaneously certainly
Row maintenance, is widely used in industry-by-industry, but it is also a big power consumption controller switching equipment.Loss to distribution transformer, people
Be usually merely observed that its active power loss, but have ignored the reactive power loss bigger than active power loss.Distribution becomes
Depressor is inductive load, and bigger its own reactive power loss of capacity is bigger.At present, the idle work(of distribution transformer is not still balanced
The reactive power compensator of rate.
The content of the invention
It is an object of the invention to provide a kind of distribution transformer reactive power compensator, to solve prior art in distribution transformer
Device reactive power is not enough, big problem is lost.
To reach above-mentioned purpose, the present invention can be adopted the following technical scheme that：
A kind of distribution transformer reactive power compensator, including controller, current transformer, voltage detecting point, it is characterised in that：Also
Including capacitor assembly；
The current transformer and the voltage detecting point are connected with the controller, and electric current, voltage signal are transmitted to institute
Controller is stated, the controller carries out calculating analysis and sends switching control signal according to the electric current, voltage signal that gather；
The capacitor assembly is connected with the controller, receives the switching control signal that the controller sends；
Wherein, the voltage detecting point is on distribution transformer low-pressure side lead or high-side lead.
The capacitor assembly includes three-phase separate-supplement capacitor assembly and three-phase total compensation capacitor assembly.
The current transformer includes high voltage side current transformer and low-pressure side current transformer.The high voltage side current is mutual
Sensor is arranged on distribution transformer high-pressure side lead, and the low-pressure side current transformer draws installed in distribution transformer low-pressure side
On line.
The controller is calculated according to low-pressure side current transformer and the electric current of voltage detecting point transmission, voltage signal
Analysis, to three-phase separate-supplement capacitor assembly switching control signal is sent, and makes distribution transformer low-pressure side three-phase reactive balance.
The controller is calculated according to high voltage side current transformer and the electric current of voltage detecting point transmission, voltage signal
Analysis, to three-phase total compensation capacitor assembly switching control signal is sent, and balances the reactive power of distribution transformer and low-pressure side.
Relative to prior art, the invention has the beneficial effects as follows balancing the reactive power of distribution transformer, reduce and match somebody with somebody
The reactive loss of piezoelectric transformer.
Description of the drawings
Fig. 1 is distribution transformer reactive power compensator principle schematic of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described.Embodiments described below is only used for more clearly from saying
Bright technical scheme, is the selected embodiment of the present invention, rather than the embodiment of whole, it is impossible to limit this with this
Bright protection domain.The every other enforcement that those skilled in the art are obtained on the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
As shown in Figure 1：The present invention discloses a kind of distribution transformer reactive power compensator, including：Controller 1, three-phase separate-supplement
Capacitor assembly 2, three-phase total compensation capacitor assembly 3, high voltage side current transformer 4, low-pressure side current transformer 5, voltage detecting
Point 6, controller 1 and three-phase separate-supplement capacitor assembly 2, three-phase total compensation capacitor assembly 3, high voltage side current transformer 4, low-pressure side
Current transformer 5, voltage detecting point 6 is all connected with.
When controller 1 receives the current signal of low-pressure side current transformer 5,6 voltage signal of voltage detecting point, work(is carried out
Rate factor is calculated, and when result of calculation display low-pressure side three-phase is idle uneven, controller 1 is to three-phase separate-supplement capacitor assembly 2
Switching control signal is sent, three-phase separate-supplement capacitor assembly 2 carries out phase-splitting reactive compensation according to control signal to low-pressure side.Work as control
Device processed 1 is detected after low-pressure side three-phase reactive balance, receives the current signal of high voltage side current transformer 4, the voltage of voltage detecting point 6
During signal, power factor calculating is carried out, when result of calculation display distribution transformer needs reactive-load compensation, controller 1 is to three-phase
Capacitor assembly 3 being mended altogether and sending switching control signal, three-phase total compensation capacitor assembly 3 carries out the throwing of capacitor according to control signal
Cut, balance the reactive power of distribution transformer and low-pressure side.
The above is only the preferred embodiments of the present invention, it is noted that to those of ordinary skill in the art,
On the premise of without departing from the technology of the present invention principle, some changes and improvements can also be made, these changes and improvements also should be regarded
For protection scope of the present invention.
