Description
Technical field
The present invention relates to wind-power electricity generation frequency conversion device, more particularly to a kind of wind-power electricity generation frequency conversion device power model Absorption Capacitance dissipates
Thermal.
Background technology
Frequency converter is important component essential in wind power generating set.Frequency converter passes through to double-fed asynchronous wind-power electricity generation
The rotor of machine carries out excitation so that and the amplitude of the stator side output voltage of double-fed generator, frequency and phase are identical with power network, and
And active and idle independent uneoupled control can be carried out as needed.Frequency Converter Control dual-feed asynchronous wind power generator realize it is soft simultaneously
Net, reduce grid-connected dash current and adversely affected to caused by motor and power network.
Existing frequency converter is made up of main circuit system, distribution system and control system.Including stator it is grid-connected switch, it is whole
It is flow module, inversion module, input/output wave filter, IGBT, PLC, JCE1000-AXS current sensor, blower fan, active
The parts such as Crowbar circuits, controller, monitoring interface.Main circuit of converter system includes rotor side inverter, dc bus list
Member, power network side rectifier.Distribution system is made up of grid-connected contactor, main circuit breaker, relay, transformer etc., and itself is integrated with
Grid-connection control system, user need not be reconfigured at grid-connection cabinet, improve level of integrated system, saved cabin space, can also have been carried in cabinet
For the 220V power supplys of field adjustable.Control system is by high speed digital signal processor (DSP), man machine operation interface and programmable patrols
Controller (PLC) is collected to collectively form.Whole control system is equipped with uninterrupted power source (UPS), is easy to system during Voltage Drop to have
Uninterrupted operation ability.
Above-mentioned each function distribution is into switch board, power cabinet, grid-connection cabinet.
Switch board：Switch board is mainly analyzed the various analog and digital signals gathered back, sends control instruction, control
The running status of current transformer.Switch board is mainly made up of Main Control Tank, PLC, wave filter, power module etc..
Power cabinet：The transmission of main responsible rotor slip energy.Power cabinet mainly by power model, IGBT, PLC,
JCE1005-FS current sensors, blower fan, active C rowbar etc. are formed.
Grid-connection cabinet：Be mainly used in current transformer be connected with generator system and power network control, the collection of number control signal with
And the configuration of secondary circuit.Grid-connection cabinet is mainly by breaker, contactor, signal collecting element, UPS, heater, signaling interface portion
Grade composition.
Power model in power cabinet is usually one group side by side, and four are provided with each power model equalizing resistance side wall
Individual Absorption Capacitance.In power model running, Absorption Capacitance produces high temperature, it is necessary to be aerated radiating because of discharge and recharge.Mesh
Before, the rear portion that above-mentioned row power model is corresponded in power cabinet is provided with horizontal heat dissipation wind channel, and blower unit passes through radiating
Air channel carries out air inducing, and radiating is aerated to power model.At present, because power model volume is larger, blower unit need compared with
High power could realize the air inducing to power model surrounding high temperature air, and heat caused by Absorption Capacitance is difficult to disperse in time,
Blower unit air inducing specific aim is not strong, not only high energy consumption, and result of ventilating heat dissipation is not good enough.
The content of the invention
Collected it is an object of the invention to overcome the deficiencies of the prior art and provide one kind for power model Absorption Capacitance
Middle ventilation and heat, radiating effect is improved, reduce the wind-power electricity generation frequency conversion device power model Absorption Capacitance heat abstractor of energy consumption.
The present invention solves its technical problem and is achieved through the following technical solutions：
A kind of wind-power electricity generation frequency conversion device power model Absorption Capacitance heat abstractor, including one group of power mould being arranged side by side
Block, power model include equalizing resistance and Absorption Capacitance, and the side of each power model equalizing resistance is mounted on one group of absorption
Electric capacity, the rear portion of power model are provided with heat dissipation wind channel, it is characterised in that：It is respectively mounted in the bottom of described each power model
One group of radiator, the position that the heat dissipation wind channel corresponds to each Absorption Capacitance are formed with air vent.
The advantages of the present invention are：
1st, this wind-power electricity generation frequency conversion device power model Absorption Capacitance heat abstractor, the bottom of each power model are respectively mounted one
Group radiator, the position that the front of heat dissipation wind channel correspond to each power model Absorption Capacitance are formed with air vent, realize to absorption
The timely forced heat radiation at electric capacity position, effectively improves the radiating effect of power model, and the smaller blower unit of use can meet to dissipate
Heat needs.
2nd, scientific structure design of the present invention is reasonable, install convenient, can effectively improve radiating effect, reduces blower unit energy
Consumption, improve power model service life.
