The utility model relates to power domain, more particularly, relates to a kind of outdoor pole-mounted reactive power compensator.
Background technology
In modern power network, due to the diversity of load, be particularly that main nonlinear-load accesses electrical network in a large number with power electronic equipment, badly influence the power supply quality of electrical network, the harm brought to electrical network mainly contains grid voltage three-phase imbalance, reactive power impact, humorous wave interference etc., thus cause interference to the power consumption equipment of electrical network, can power consumption equipment be damaged when operating mode is severe.Current optimal scheme adopts reactive power compensating apparatus (SVG) exactly, in order to improve the stability of electrical network, strengthens ability to transmit electricity, eliminates reactive power impact, filtering harmonic wave, balance line voltage.
Outdoor pole-mounted SVG, as its name suggests, application scenario is main out of doors, the many outdoor transformers in electrical network in infield, and being on the post of 2 ~ 3 meters of positions apart from ground level, therefore certain requirement is proposed to the size of outdoor pole-mounted SVG, simultaneously, the outdoor transformer of different capabilities is also different to the capacity requirement of pole SVG, and capacity is larger, and the size of SVG also can correspondingly increase.
Outdoor pole-mounted SVG, comprises main power circuit unit, power supply circuit unit, control protection electric circuit unit and auxiliary circuit; Above-mentioned main power circuit unit comprises DC energy storage electric capacity, full control device Commutation device IGBT, canned power inductance, filter capacitor, inductance keyset, exchanges the components and parts such as plate and direct current plate; Above-mentioned power supply circuit unit comprises multi-circuit power supply conversion circuit etc.; Above-mentioned control protection electric circuit unit comprises control protection electric circuit plate, gate-drive control circuit board, capacitor switching control circuit board, DTU (Data Transfer Unit) circuit for remotely controlling module etc.; Above-mentioned auxiliary circuit comprises the components and parts such as radiator, blower fan, temperature and humidity controller.
The outdoor pole-mounted SVG be made up of above-mentioned 4 partial circuits, is limited to the requirement of size, so the connected mode between each several part circuit determines the size of SVG.Conventional SVG each several part circuit takes cable to connect more, due to SVG capacity requirement, output current as 75kVarSVG has 113A, the cable size adopted in SVG main power circuit reaches the specification of 50 square millimeters, consider that the radius bend of cable and the layout in SVG inside can take very large space, this increases the size of SVG undoubtedly, and SVG size increases the impact brought and is raising structural design difficulty, increases installation difficulty, and this is also the critical defect of conventional outdoor pole-mounted SVG.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of outdoor pole-mounted reactive power compensator, not only can effectively reduce SVG size, make the topology layout of SVG more reasonable, and enable SVG post be easier to install out of doors, thus solve this key issue of SVG size.
For achieving the above object, the utility model adopts following technical scheme:
A kind of outdoor pole-mounted reactive power compensator, comprise be arranged in order from top to bottom top layer, middle level and bottom three-decker, wherein, described top level structure comprises control protection electric circuit plate, power supply circuit plate, DTU circuit for remotely controlling module, temperature and humidity controller and heater;
Described media layer damage comprises upper strata and lower floor, be provided with in described upper strata and exchange plate, direct current plate and capacitor switching control circuit board, inductance keyset is provided with in described lower floor, described direct current plate is provided with DC energy storage electric capacity and gate-drive control circuit board, described interchange plate is provided with filter capacitor, also be provided with radiator between described upper strata and lower floor, described radiator set firmly IGBT, radiator is also provided with blower fan;
Described fabric comprises canned power inductance.
Described capacitor switching control circuit board is fixedly arranged on the top exchanging plate.

Described direct current plate is connected with described inductance keyset by copper stud.
Compared with prior art, a kind of outdoor pole-mounted reactive power compensator of the present utility model is adopted to have following Advantageous Effects:
1) in the stacked board structure of use, by each several part board hierarchical layout, and adopt copper stud to connect between main power circuit plate, copper stud had both served electrical connection effect, play support structure again, thus the cable that instead of inner 50 square millimeters of SVG connects, effectively by within SVG dimension reduction to designing requirement;
2) after adopting stacked board to design, in main power circuit unit, heating element is also corresponding to non-heating element separates, and concentrate by thermal source and dispel the heat, SVG can adopt the blower fan of smaller power, reduces SVG size further;
3) adopt the outdoor pole-mounted SVG structure of stacked board method for designing simple, and easy for installation, universal flexible, reliable and long service life.
In a word, the utility model has considered the impact of the factors such as the decomposition of each several part circuit function in prior art, the characteristic of single components and parts and size, by stack design method, adopt the hierarchical layout connected based on copper stud, 4 partial circuits of existing SVG have been re-started integration.It is simple that outdoor pole-mounted reactive power compensator of the present utility model has structure, the features such as easy for installation, universal flexible, reliable, long service life.
