Description
Technical field
Reactive power compensator (the SVG that the utility model relates to be applied in electric system；English Static Var
The abbreviation of Generater), more particularly, to power cabinet energy-saving radiating system.
Background technique
Reactive power compensator is widely used in remote distance power transmission, city secondary substation, electric arc furnaces, milling train and promotion
The engineering fields such as machine, regional power grid, photovoltaic power generation, wind power plant, electric locomotive power supply.China Middle Line Project For Transferring Water From South To North general main canal Henan
Section, Hebei Section set 35kV power supply system private network, transmission line length about 1100km, by 35kV route, center switch station, along the line bear
Lotus point step-down substation composition, power supply are total along route quoted from the 35kV bus in 110~220kV of local power network substation along the line
13 35kV center switch stations are set, and 1 to 2 circuit 35kV electricity is drawn at each center switch station from the electric system of location
2 circuit 35kV routes are drawn respectively to trunk canal upstream, downstream two sides radiation type electric supply, in trunk canal load point from center switch station in source
Place sets 35kV/0.4kV step-down substation and powers to load point, along the line load point step-down substation 309.To guarantee the south water to north
The power supply quality of middle line general main canal 35kV power supply system installs at 35kV center switch station and load point step-down substation equipotential
Reactive power compensator.
Currently, the power cabinet in commercially available reactive power compensator is complete machine cabinet gang configuration, complete machine box house includes
Several independent power component modules for realizing different function, each power component module are encapsulated by shell, power component
Inside modules include several electronic components and connecting wire.The heat dissipation of the reactive power compensator include cooling electronic component,
Modular unit heat dissipation, complete machine heat dissipation, environment temperature improve multiple links such as heat dissipation, each heat dissipation link requires air draft pair
Stream, forms eclipsed form air discharging and radiating structure as cost to consume the energy.The heat-removal modalities of above-mentioned reactive power compensator are carried out detailed
Known to subdivision analysis: electronic component considers that the heating temperature of itself increases, and the fever feature of Single Electron component is fever function
Rate is smaller, but fever can lead to electronic component temperature rise it is very high, the area in electronic component external envelope face is smaller, heat dissipation
Limited area needs to combine electronic component configuration heat dissipation base and fan；Small-sized fans are set and are directed at electronic component key
Heating position blowing convection current realizes electronic component cooling purpose, heat is drained into the module integral box where electronic component
In vivo；By multiple heating electronic component comprising modules units in module integrated cabinet, to guarantee the environment temperature in modular unit
Degree is met the requirements, and integrates box enclosure setting air draft heat loss through convection in module, the heat generated in module integral box is drained into complete machine
In cabinet；Complete machine cabinet setting exhaust blower drains into the heat that all modular units generate outside complete machine cabinet.Due to idle benefit
It repays device to be arranged in building, for the operating ambient temperature for guaranteeing reactive power compensator, needs to be arranged ventilation or air conditioner refrigerating
Equipment will be outside the heat dissipation to building in building.This eclipsed form air discharging and radiating structure is caused, to find out its cause, 1, electricity
Sub- device manufacturer only considers the radiating requirements of electronic device itself, small to meet the environment temperature setting that electronic device works
Type fan, using in ventilation and heat to module integral box；2, module Integrated manufacture quotient is also to consider that the heat dissipation in module range needs
It asks, meets operating ambient temperature in module integral box, fan is set, using in ventilation and heat to complete machine box body；3, idle benefit
The product of the complete producer's procurement module Integrated manufacture quotient of device is repaid, setting exhaust blower drains into the heat that all modular units generate
Outside reactive power compensator；4, engineering design enterprise only considers the heat dissipation of reactive power compensator complete set of equipments or in building
The heat of reactive power compensator complete set of equipments is drained into outside building or is by idle benefit by aperture setting ventilation blower on wall
The heat for repaying device complete set of equipments drains into Indoor environment, and air-conditioning equipment is in addition arranged again by Indoor environment heat and drains into building
Beyond the region of objective existence portion.Difference manufacture businessman only considers the environmental condition of oneself supplied equipment, and setting radiating mode meets working environment
Condition requirement, the unified reasonability for considering reactive power compensator complete set of equipments holonomic system radiating mode, existing for not
Foot place shows the following aspects:
1, there are energy wastes for the eclipsed form air discharging and radiating structure of reactive power compensator.The power cabinet of reactive power compensator
Traditional heat-dissipating mode be ventilation and heat, reactive power compensator cooling vent inlet and outlet Air Temperature Difference is small, rely primarily on by
Grade is reinforced, stronger ventilation amount realizes heat dissipation, and radiate process are as follows: all multiple electronic component fever → ventilation and heats are integrated to module
In case → module integrates box enclosure setting air draft heat loss through convection → heat and drains into complete machine box house → complete machine cabinet setting air draft
Machine heat dissipation → heat drains into outside complete machine cabinet → and building dress air-conditioning or building wall wall blower by air draft drain heat
It is outer that → heat drains into building.Eclipsed form air discharging and radiating is low to the utilization efficiency of the required energy.
2, the eclipsed form air discharging and radiating structure heat dissipation effect of reactive power compensator is poor.Ventilation is set by the heat in building
It is discharged into outside building, building side wall drives air holes into, and interior of building temperature differs not with building ambient temperature
Greatly, especially in summer high temperature season, equipment operating environment temperature is higher, and interior of building temperature is high, building external environment
Temperature is also high, is unfavorable for reactive power compensator heat dissipation.Meanwhile building side wall drives air holes, the extraneous tiny dust of building into
Interior of building is sucked with air-flow, the air inlet hole strainer of reactive power compensator is easy blocking, needs artificial frequently cleaning inlet side
Strainer, operation and maintenance amount are big.
If 3, building side wall not aperture, takes and hot-air is come room in the cabinet top installation exhaust blower of reactive power compensator
It is interior, indoor heat is drained into outdoor by way of indoor location air-conditioning；Which solves the air inlet hole of reactive power compensator
Filter net jam problem does not need artificial frequently cleaning air inlet side screen, but the energy of air conditioner refrigerating discharge interior of building heat
Utilization efficiency is lower by the efficiency of energy utilization outside heat dissipation to building than using exhaust blower.
