Technical field

The utility model relates to mesohigh general convertor field, relates in particular to a kind of intensive SVG of 35kV direct screening based on multiple unit combination drawer type power model.

Background technology

In the prior art, 35kV direct hanging type SVG has become the main developing direction of SVG field 35kV electric pressure because of advantages such as it can cancel step-down transformer, rated current is little and then the IGBT on-state loss is little, caloric value is little.Generally, the live part of high-pressure reactive compensation device SVG, control cubicle, a plurality of power cabinet are independently cabinet, and its spatial placement form is to be arranged in order; Because of the electric pressure of 35kV direct screening SVG is high, dielectric voltage withstand requires high, and power unit cascade progression is many, is connected through cable, control line respectively between live part, control cubicle and each power cabinet.Because the layout of existing structure, cause each other line many and grow, staggered complicated, be not easy to assembling keep in repair; Power cell in power cabinet vertical row is respectively put, and for making things convenient for installation and connection, needs between power cell to guarantee certain interval, makes the power cabinet volume bigger; And the layout of a plurality of big volume cabinet spaced apart makes that high-pressure reactive compensation device overall structure volume is big, and floor space is big, and cost is high, and power density is low.

Summary of the invention

The purpose of the utility model provides line between a kind of compact in design, the cabinet unit easily based on the 35kV direct screening integrated form SVG of multiple unit combination drawer type power model; Every phase power cabinet cabinet is the integrated structure of three row power cell left and right sides structural configuration; Every row power cabinet is made up of the vertical arranged stacked of a plurality of drawer type power models; And each power cell internal components employing compact integrated morphology, be convenient to production, deposit, installation, expansion, maintenance and the transportation of power cell.

For realizing above-mentioned purpose, the utility model is realized through following technical scheme:

A kind of intensive SVG of 35kV direct screening based on multiple unit combination drawer type power model; Comprise power cabinet, control cubicle and live part; The every of described power cabinet cabinet is made up of three row power cells; Every row power cell is made up of the vertical arranged stacked of a plurality of power cell drawers, whenever is connected in series between each drawer power cell in mutually.

Described every phase power cabinet is the integrated structure of the left and right sides structural configuration of three row power cells composition.

Described power cabinet cabinet rear portion is provided with supports the electric capacity mounting portion, is the structure of split according to the capacitive part and the power cell of the requirements extend of place capacity.

The power cell of a plurality of same structures is set in described each power cell drawer, separates through insulating barrier between each power cell; Each power cell is made up of drive controlling plate, full-control type device, radiator, thin-film capacitor, the integrated integrated morphology of each device of power cell.

Described each power cell internal components is stacked cramped construction, and the drive controlling plate is positioned at the superiors, and the full-control type device is positioned at drive controlling plate bottom, and the full-control type device connects radiator, and the full-control type device is installed on the composite bus bar; The sidepiece of full-control type device is provided with thin-film capacitor.

Compared with prior art, the beneficial effect of the utility model is:

1) each phase power cabinet is the version of the integrated intensive style of three row power cells, compact conformation, and can reducing at least of the more split type layout of volume adopts busbar directly to connect between 1/2, three column unit, and reliability is high, and cost is low.

2) power cell adopts the vertical range upon range of mounting means of drawer structure, vertically is connected in series between power cell, and the corresponding phase of per three row reduces floor space.

3) power cell of a plurality of same structures is arranged in the drawer, and novel structure has reduced occupation space greatly, and volume greatly reduces with respect to the march-past power cell, is convenient to install, debugs, safeguards, transports.Power cell is installed and is adopted free fast insert-pull connected mode, is convenient to production reserve, installation, expansion, maintenance and the transportation of power cell, highly versatile.

4) the support electric capacity of power cabinet domestic demand expansion and power cell split are provided with, and can conveniently expand, and be very convenient by the supporting electric capacity of place capacity demand.
