Description

A kind of wind-power electricity generation frequency conversion device external cable copper bar connecting structure
Technical field
This utility model relates to copper bar connecting structure, connects particularly to a kind of wind-power electricity generation frequency conversion device external cable copper bar Structure.
Background technology
Converter is requisite vitals in wind power generating set.Converter is by double-fed asynchronous wind-power electricity generation The rotor of machine carries out excitation so that the amplitude of stator side output voltage of double-fed generator, frequency are identical with electrical network with phase place, and And meritorious and idle independent uneoupled control can be carried out as required.Frequency Converter Control dual-feed asynchronous wind power generator realize soft also Net, reduces the adverse effect that motor and electrical network are caused by grid-connected dash current.
Existing converter is made up of main circuit system, distribution system and control system.Including the grid-connected switch of stator, whole Flow module, inversion module, input/output wave filter, IGBT, PLC, JCE1000-AXS current sensor, blower fan, active The parts such as Crowbar circuit, controller, monitoring interface.Main circuit of converter system comprises rotor side inverter, dc bus list Unit, grid side commutator.Distribution system is made up of grid-connected catalyst, main circuit breaker, relay, transformator etc., and self is integrated with Grid-connection control system, user need not be reconfigured at grid-connection cabinet, improve level of integrated system, has saved cabin space, also can carry in cabinet 220V power supply for field adjustable.Control system is by high speed digital signal processor (DSP), man machine operation interface and able to programme patrols Collect controller (PLC) to collectively form.Whole control system is equipped with uninterrupted power source (UPS), it is simple to during Voltage Drop, system has Uninterrupted operation ability.
Above-mentioned each function is assigned in switch board, power cabinet, grid-connection cabinet.
Switch board: the various analog and digital signals gathered back are mainly analyzed by switch board, send control instruction, controls 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 main transmission being responsible for rotor slip energy.Power cabinet mainly by power model, IGBT, PLC, JCE1005-FS current sensor, blower fan, active C rowbar etc. are constituted.
Grid-connection cabinet: be mainly used in current transformer be connected with generator system and electrical network control, number control signal collection with And the configuration of secondary circuit.Grid-connection cabinet is mainly by chopper, catalyst, signal collecting element, UPS, heater, signaling interface portion Grade composition.
Need to be attached by copper bar between the internal reactor of converter and converter external cable, and reactor There are three horizontally arranged terminals rear end, it is therefore desirable to be attached by three groups of copper bars.Owing to external cable is relatively thicker, copper bar Length is longer, and simple can cause the deformation of copper bar in work process by copper bar connection, affect converter normal, stablize work Make.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one can guarantee that reactor and external cable Between connection reliability, strengthen copper bar connective stability wind-power electricity generation frequency conversion device external cable copper bar connecting structure.
This utility model solves its technical problem and is achieved through the following technical solutions:
A kind of wind-power electricity generation frequency conversion device external cable copper bar connecting structure, including reactor, reactor rear end has level to set Three terminals put, it is characterised in that: three described terminals connect horizontal copper bar respectively, and described horizontal copper bar connects perpendicular respectively Straight copper bar, the lateral symmetry at reactor is installed with connecting plate, and between these two connecting plates, level fixed installation one is solid Determining beam, on this fixing beam, corresponding described three vertical copper bars are installed with gripper shoe, this gripper shoe and described vertical copper bar Between use double insulating bolt to be fixed support.
And, described horizontal copper bar is flexible connection copper bar.
And, it is fixed by bolt between described horizontal copper bar and vertically copper bar.
Advantage of the present utility model and having the beneficial effect that
1, this wind-power electricity generation frequency conversion device external cable copper bar connecting structure, three terminals connect horizontal copper bar, level respectively Copper bar connects vertical copper bar respectively, and the lateral symmetry at reactor is installed with connecting plate, water between these two connecting plates Beam is fixed in flat fixed installation one, and on this fixing beam, the corresponding vertical copper bar of above three is installed with gripper shoe, this gripper shoe And using double insulating bolt to be fixed support between vertical copper bar, reactor obtains reliable guarantee with the connection of external cable, And strengthen copper bar stability, deformation will not be caused because of the vibration in work process.
2, this wind-power electricity generation frequency conversion device external cable copper bar connecting structure, horizontal copper bar is flexible connection copper bar, it is to avoid electricity Anti-device terminal deforms because copper bar is really up to the mark when being connected with copper bar, strengthens the reliability and stability connected.
3, this wind-power electricity generation frequency conversion device external cable copper bar connecting structure, passes through bolt between horizontal copper bar and vertically copper bar It is fixed, it is ensured that connective stability and reliability, it is to avoid connect and loosen the normal work of impact.
4, this utility model scientific structure design is reasonable, it is ensured that the connection reliability between reactor and external cable, increases The connective stability of strong copper bar.
