A kind of magnet controlled fast chopper
Technical field
The utility model is related to a kind of magnet controlled fast chopper.
Background technology
Continuous development and environmental protection characteristic that is perfect and having with vacuum interrupter, vacuum Breaker is used widely.Operating mechanism is always the short slab of breaker development, to action Reliability improvement is little.At present main operating mechanisms have spring operating mechanism and permanent magnet mechanism two big Type.The more commonly used spring operating mechanism has been continued to use more than 30 years, and technology falls behind relatively, knot Structure is complicated, and machine components are more, are easier the phenomena of the failure such as mechanism's screens occur usually.At present According to the statistics of domestic external switch operation troubles rate, the failure for having more than 70% is all from operating mechanism Mechanical part;The breaker electrical control driving part fault rate of permanent magnet mechanism is also very high.
Recent years, although the optimization design and permanent-magnet operating mechanism of spring operating mechanism is not It is disconnected perfect, to improving breaker total quality, serve larger effect.Because comparison is traditional Spring operating mechanism and permanent-magnet operating mechanism improve breaker closing speed in terms of receive To considerable restraint, its combined floodgate power is high to power requirement, it is desirable to improve capacity again all than larger, It is limited by various factors.
The manually or electrically behaviour that now most of spring operating mechanisms and permanent magnetic mechanism switch are adopted Make, do not affected by supply voltage substantially, higher closing speed can be obtained and realized automatically Reclosing, reduces to a certain extent fault rate.But for the structure of spring mechanism itself, Amount of parts is relatively more, about more than 180.Have high demands in machining accuracy, manufacture work Skill is also more complicated.
The main devices that permanent magnet mechanism is kept using permanent magnet as closing a floodgate, control is using the electricity that charges Discharge capacitor excitation mode, operation power is than larger, and drive circuit fault rate is higher, and close a floodgate behaviour Make startup needs and overcome intrinsic permanent magnet magnetic, so receiving very much in terms of on/off switch speed is lifted Limit, wants higher lifting breaker overall performance aspect difficulty still than larger.
Conventional spring mechanism parts are more, and failure rate of machinery is high, and data consistency is poor, phase For grid cyclic wave data 20ms, it is impossible to breaker is reached and is precisely controlled.Life of product Comparison is short, while increased the working service amount and practical application difficulty of this equipment.Permanent magnetism is grasped Make mechanism's breaker electrical control fault rate higher, need to overcome permanent magnet itself during action Weight and magnetic force is used, operation needs power big, breaker is reached and is precisely controlled.
