Description
Technical field
The utility model relates to technical field of wind power generator, relates in particular to safety automatic braking device of wind driven generator.
Background technique
Wind generating unit is in the physical environment, wind speed change frequent and excursion greatly, variation of ambient temperature is big, thereby bad working environment usually can cause generator hypervelocity, overheated, overload and the fault that causes.For guaranteeing that the wind-power electricity generation function runs well for a long time, must be provided with hypervelocity, overheated, overload safety device on wind-driven generator.
In notice of authorization day is that November 3, notification number in 2010 are that the utility model patent that CN201623261U, name are called " safety automatic braking device of wind driven generator " has disclosed a kind of safety automatic braking device of wind driven generator, and its magnetic clutch is made up of the external friction dish of armature, electromagnetic coil, clutch land, clamping clutch land and internal friction disc, and the dc low-voltage electricity that the magnetic clutch in its safety catch is provided by electric controller immediately is with the magnetic clutch coil electricity; And in normal operation; Electromagnetic coil is switched on always, holds external friction dish and the internal friction disc that ring armature reaches the clamping clutch disk that links together with ring armature and drag, and the clutch land is separated with generator amature; Though this model utility has realized braking and has resetted; But down, always switch on, therefore in working order by electromagnetic coil for this technological scheme; Wind-driven generator is when running is initial; Produce the electromagnetic wave mutual interference mutually of electromagnetic wave that the magnetic clutch coil sends and generator operation, strengthened the starting torque of wind-driven generator, and because in working order time; Electromagnetic coil is switched on always, and power consumption is quite big.
The model utility content
The utility model to magnetic clutch coil in the existing technology in working order down; Electromagnetic coil switches on always, make the electromagnetic wave mutual interference mutually of the electromagnetic wave that sends and generator operation; Thereby the starting torque of the generator that breezes up, the defective that power consumption is big; When a kind of off-position is provided with the safety automatic braking device of wind speed running; Thereby wind-driven generator does not have the electromagnetic influence of magnetic clutch coil when running is initial, has reduced the starting torque of wind-driven generator, has saved electric energy.
In order to solve the problems of the technologies described above, the utility model is realized through following technological scheme:
A kind of safety automatic braking device of wind driven generator; Comprise stator, stator axis and rotor; On one end of said stator axis the magnetic clutch parts are installed; Described magnetic clutch parts comprise armature, electromagnetic coil and brake assemblies, and described brake assemblies comprises clutch stop disk, external friction dish, internal friction disc, spring, the backing plate that the union with rotor connects, and described armature is provided with the connection push rod; Described armature is connected with brake assemblies through connecting push rod, and described electromagnetic coil is connected with electric controller.
Above-mentioned described a kind of safety automatic braking device of wind driven generator, described external friction dish, internal friction disc and spring are through being bolted on the backing plate, and described armature is connected with the backing plate of brake assemblies through connecting push rod.
The setting that faces down of above-mentioned described a kind of safety automatic braking device of wind driven generator, the adhesive of described electromagnetic coil, described armature is arranged at the below of electromagnetic coil adhesive face.
It is that November 3, notification number in 2010 are that CN201623261U, name are called the utility model patent of " safety automatic braking device of wind driven generator " that the utility model is compared notice of authorization day in the existing technology; The armature of existing technology is arranged at the top of electromagnetic coil adhesive face; And the utility model armature is arranged at the below of electromagnetic coil adhesive face; And in the magnetic clutch parts, be provided with the connection push rod, safety automatic braking device of wind driven generator is anti-dress formula, after wind-driven generator is installed; The electromagnetic coil generating signal of need not electric controller giving the magnetic clutch parts in the safety automatic braking device; Make its energising, the magnetic clutch parts are at uncharged state in the safety automatic braking device, therefore with brake assemblies that generator is connected in clutch stop disk also just with generator in disengaged position.Wind-driven generator through wind speed drive fan blade, wind wheel starts rotary electrification with wind speed; And when wind-driven generator exceeds the speed limit, during overheated, overload situations, electric controller sends the electromagnetic coil energising that electric signal is given the magnetic clutch parts in the safety automatic braking device.This moment, the magnetic clutch parts sucked the armature in the native system; Being connected push rod by four that are connected with the armature assembling then is connected on the brake assemblies; Brake assemblies promotes clutch stop disk and is cut into the union on the generator amature; Cause wind-driven generator to carry out emergency braking, play the safety protection effect.
The utility model has following beneficial effect:
1, wind-driven generator need not to give for a long time the power supply of the magnetic clutch parts in the safety automatic braking device in normal working.Have only when wind-driven generator exceeds the speed limit, overload, when overheated; Electric controller is collected signal; Just give the energising of magnetic clutch parts sender; Need not to give the power supply of magnetic clutch parts for a long time, thereby make the electric controller of wind-driven generator itself will consume the electric energy of storage, make wind powered generator system save electric energy greatly.
2, safety automatic braking device of wind driven generator is to be connected on the stator axis with rotor, stator.Therefore very near from stator, rotor, also generate electromagnetic waves after the energising of magnetic clutch parts, just the magnetic wave with generator produces mutual cross interference; When wind-driven generator in when work; Adopt two kinds of methods respectively, the one, the energising of magnetic clutch parts sucks brake disc, the 2nd, magnetic clutch parts no electric circuit; When equal rated speed, the utility model can increase greater power generation power.
3, owing to exist during the safety automatic braking device of wind driven generator adhesive of existing technology and produce mutual cross interference between magnetic wave and the magnetic field, therefore increased starting torque.Through the energising of magnetic clutch parts, two kinds of method testing wind power generations of no electric circuit machine starting torque, the utility model has reduced the starting wind velocity of wind-driven generator, and effect is obvious.
