Description
Technical field
The utility model relates to a kind of low-voltage reactive compensator capable SVG structure.
Background technology
A large amount of motor inductive loads that use in factory's distribution system, these loads will consume a large amount of reactive powers, and reactive power needs compensation, to improve power factor, increases the service efficiency of transformer.For compensation network reactive power, conventionally adopt power capacitor local compensation reactive power, its capacity of capacitor compensation is fixed, or there is level adjustable, when steady load, power factor compensation successful, but when load fluctuation is large, capacitor compensation does not just catch up with the variation of load, do not reach timely compensating power, so just bring the bad shortcoming of power factor compensation effect, therefore, in recent years, appearance as dynamic reactive compensation device looks like to emerge rapidly in large numbersBamboo shoots after a spring rain, as: static var compensator, adopt the TSC device of controllable silicon quick-switching capacitor, etc., the reactive power compensator (SVG) of the employing power device conversion particularly occurring is recently that a kind of speed is faster, the reactive power compensator that does not need AC capacitor, can send active power, also can send reactive power, beneficial to stablizing electrical network like this.This device can be widely used in electrical power trans mission/distribution system and improve power system operation stability, improve power factor, reduce line loss and improve the quality of power supply, and in grid-connected power generation system as the occasion of photovoltaic or wind power station, can maintain by the idle adjusting of this device the voltage stability of load side voltage and regulating system, a kind of low-voltage reactive compensator capable SVG structure is exactly custom-designed a kind of device in order to meet at present the requirement of dynamic compensation reactive power fast, power device IGBT, charging direct current capacitor, connect busbar, IGBT absorption capacitor group, blower fan, radiator, control board is by reasonably design, install and consider ergonomics principle and meet electric operation requirement and be integrated in a device type, at present in technology, SVG structure is mostly bulky, complex structure, poor anti jamming capability, be unfavorable for inspection and maintenance, in use because heat radiation is bad, easily break down, and then have influence on the normal operation of whole SVG device.
Utility model content
The utility model object is exactly in order to make up the defect of prior art, and a kind of low-voltage reactive compensator capable SVG structure is provided.
The utility model is achieved through the following technical solutions:
A kind of low-voltage reactive compensator capable SVG structure, include control cabinet, on described control cabinet base plate, radiator is installed, IGBT module is installed on described radiator, IGBT module Absorption Capacitance is directly installed on IGBT module pin, IGBT module DC side adopts stack bus bar to connect charging capacitor group, charging capacitor group is arranged on the iron plate of control cabinet both sides, control board is installed in IGBT module dead ahead, described control board is connected with IGBT module by control line, in described control cabinet, bottom is provided with cooling fan, cooling fan mouth is directly aimed at radiator, main outgoing line busbar is installed on described control cabinet top.
Described radiator fan is arranged on the bottom of control cabinet, adopts air draught radiating mode, and IGBT module is arranged on the place of the radiator air inlet 50mm of place, good heat dissipation effect, and assembling is easy to maintenance.
The utility model has the advantages that: the utility model is simple in structure, connection and reasonable arrangement, volume is little, the connection busbar of IGBT module and charging capacitor group adopts stack bus bar, reduced the impact of common busbar inductive sensor on convertor assembly SVG performance, adopt air draught radiating mode, IGBT module is arranged on air inlet place, cool breeze is beneficial to IGBT module heat dissipating, control board is installed nearby above IGBT module 1, control line is short, improved antijamming capability, the integral installation of charging capacitor group is in control cabinet both sides, be directly connected in stack bus bar, repair and replacement are convenient, taken into full account the operation characteristic of electric elements, connection and reasonable arrangement is attractive in appearance, can standardization, modularization is produced, improved product quality, also improved production efficiency.
