Description
Technical field
The invention belongs to the power transmission and transforming equipment technical field, particularly a kind of operation machine for cylinder permanent magnetic line motor of high-voltage breaker is applicable to the intellectualized operation of circuit breaker.
Background technology
For primary cut-out, require operating mechanism can obtain higher divide-shut brake speed, can realize the automatic reclosing operation again fast.Operating mechanism occupies critical role in circuit breaker.It not only will guarantee the reliable in action that circuit breaker is long-term, and will satisfy the requirement of arc quenching characteristic to operating mechanism.The divide-shut brake required time of circuit breaker and speed must satisfy it cut-offs and requirement is closed in the pass, and fault is enlarged, and keeps the stable of electric power system, and the damage that can alleviate equipment, circuit.Require circuit breaker to have good operating characteristics, to satisfy above-mentioned requirements for this reason.Mainly contain hydraulic actuating mechanism, spring operating mechanism or pneumatics etc. for existing operating mechanism, mostly be made of a whole set of mechanical device, parts are many, the transmission mechanism complexity, and the manufacture process requirement height, and motion process is uncontrollable.
Summary of the invention
For solving the deficiency of existing breaker operation mechanism, the invention provides a kind of operation machine for cylinder permanent magnetic line motor that is used for primary cut-out, operation machine for cylinder permanent magnetic line motor of high-voltage breaker of the present invention is made up of cylinder permanent magnetic line motor and transmission mechanism.
Cylinder permanent magnetic line motor comprises elementary iron core, permanent magnet, secondary iron core, electric machine main shaft, armature winding, radially be distributed as successively from inside to outside: electric machine main shaft, secondary iron core, permanent magnet, armature winding, elementary iron core, elementary iron core is cylinder type, elementary iron core forms several flute profile structures by silicon steel plate stacking, at the middle part of elementary iron core fluting, and in groove, place armature winding, secondary iron core is cylindrical, post permanent magnet on the secondary iron core, permanent magnet constitutes the magnetic pole of cylinder permanent magnetic line motor, armature winding is arranged apart from the mode of winding by concentrated the putting in order of individual layer in groove, and armature winding feeds monophase current.The main shaft of cylinder permanent magnetic line motor is connected by transmission mechanism with the moving contact of primary cut-out, cylinder permanent magnetic line motor has been installed permanent magnet on secondary iron core, set up main field by permanent magnet, in the armature winding of cylinder permanent magnetic line motor, feed direct current, the electrical conductor effect that is subjected to power in magnetic field just drives secondary motion unshakable in one's determination like this, and secondary iron core then drives the moving contact of breaker motion by linkage.
Advantage of the present invention: shortcomings such as the volume that operation machine for cylinder permanent magnetic line motor of high-voltage breaker has overcome traditional operating mechanism is big, transmission mechanism is complicated, the response time is long and motion process is uncontrollable, broken through the principle of mechanism kinematic on the traditional sense, thereby the electromagnetic push that utilizes motor self to produce drives the branch/combined floodgate of contact of breaker.For cylinder permanent magnetic line motor it to have the quality of mechanism little, movement inertia is little, kinetic energy reduces greatly, makes energy loss little, has improved efficient; Its reliability is better, and it is controlled to have high response and high-precision characteristics and a motion process.
