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 IGBT startup
Heating arrangement.
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 Absorption Capacitances are provided with each power model.
In power model running, Absorption Capacitance produces high temperature, it is necessary to be aerated radiating because of discharge and recharge.By products application institute
It is universal to locate regional high humidity weather, extremely regional relative air humidity 95%-100%, therefore power model internal operation and storage
Environment very severe.In the prior art, it is essentially all to be prevented by the degree of protection of cabinet where strengthening power model
Tide, can be due to the ventilation and heat needs of air-cooled power model, it is impossible to make the cabinet being fully sealed, outside highly humid air must
So by fresh air inlet ingoing power inside modules power model Primary Component can be caused to make moist.
Power model makes moist, and when equipment starts, electric leakage and the danger burst is not so easily produced, even if this case has small electricity
Flow-thru electrode, there is also danger.At present, common dehumanization method is to power model by dry heater and force ventilation method
The devices such as IGBT are dehumidified, but without heat input, effect on moisture extraction is bad, and dehumidify optimum level namely maintain with it is wet
The same humidity of air, it is impossible to thoroughly solve problem of making moist.Applicant have developed a kind of installation PTC adding thermal resistances on a heat sink
Mode, to radiators heat, IGBT is heated indirectly, while be aided with blowing, heating and dehumidification efficiency can be improved.But
This structure adds man-hour requirement to pass through multiprogramming, gluing sealing, screw fixation etc. in new equipment；For the old equipment installed
Transformation, exist it is not easy to install, the problem of wasting time and energy.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide it is a kind of efficiently, it is reliable, thoroughly possess protection against the tide and remove

Paste and silica gel heating sheet is installed, a binding post of silica gel heating sheet is connected to temperature detect switch (TDS) by binding post, and silica gel adds
Another binding post of backing is connected to power line by binding post.
Moreover, described binding post is fixedly installed in the mounting bracket in the power cabinet cabinet on horizonal base plate.
Moreover, the temperature detect switch (TDS) selects closed type temperature detect switch (TDS).
Moreover, described silica gel heating sheet is by two layers of silicon rubber high-temperature insulation cloth and internal nichrome heating wire group
Into being formed with mucigel in the outer surface of one layer of silica gel high-temperature insulation cloth.
The advantages of the present invention are：
1st, this wind-power electricity generation frequency conversion device power model IGBT startup heating arrangement, can be realized by silica gel heating sheet to dissipating
The heating of hot device, realize indirectly to IGBT heating and dehumidification, before power cabinet startup optimization, first by silica gel heating sheet to IGBT
And its driving plate is dehumidified, Moistureproof dehumidification function when equipment starts is realized, power model is solved and is deposited in high humidity environment
There is the problem of moisture damage in storage and operation；Have the advantages that protection against the tide is reliable, dehumidifying is thorough, can efficient process condensation problem.
2nd, this wind-power electricity generation frequency conversion device power model IGBT startup heating arrangement, can be realized by silica gel heating sheet to dissipating
