Background technology
Miniature reclosing is widely used in unmanned base station, distribution terminal, rural power grids etc., automatic or long-range to solve
Control divide-shut brake.After circuit failure makes circuit breaker trip, auto recloser closes through the short time after disconnected again
Road device.In most cases, line fault (such as lightning stroke, windburn) is temporary, the insulation of circuit after circuit breaker trip
Performance (insulator and the air gap) can be restored, and overlap the reliability for improving power system power supply again.
Miniature autoreclose breaker gradually obtains the extensive use of people, and power supply management, power supply quality are improved
It is very helpful.Automatic reclosing brake structure has cylinder to push (including liquid, gas phase change etc.), motor operation, three kinds of electromagnet.
Phase transformation cylinder pushes the response time slow, and motor gear operating cost is high, complicated, and electromagnet volume is big, of high cost.This hair
Bright to solve to propose a kind of novel actuating mechanism constituted using memory alloy properties, occupancy is small, at low cost, reliability is high,
The defect that the miniature reclosing device of existing market is of high cost, reliability is low, mechanism is complicated can be overcome.
Marmem (shape memory alloys, abbreviation SMA) is a kind of New temperature phase-change material, this
Material have shape memory effect, superelastic effect and higher power to weight ratio, as the driving element of driver aviation,
The fields such as space flight, medical treatment are widely used.
Shape-memory alloy wire has following characteristic：After shape-memory alloy wire is elongated, mechanically to shape
Memory alloy wire applies constraint, is then heated to shape-memory alloy wire, and due to the phase change induction that inside occurs, shape memory closes
Spun gold is restored to original length, shows shape memory effect, will produce certain reply in the case that both ends are constrained
Power.
Invention content
