Protecting system.
Background technology
Air environmental pollution is on the rise in recent years, and national emphasis one, tier 2 cities are influenced to different extents, special
It is not that extensive haze weather frequently occurs, and has a strong impact on people's daily life, while right after northern China city enters winter
Body also results in unpredictable damage.In addition global environment temperature gradually rises, and South Pole iceberg storage gradually reduces, sea
Water front slowly rises, and for this, the United Nations repeatedly holds environmental protection meeting, confers countries in the world Combined Protection environment, wherein emphasis
Work is to reduce carbon emission amount, actively develops new energy.The call of Chinese active response the United Nations, progressively carry out new energy item
Mesh, stop the heavily contaminated power generation project construction such as thermoelectricity.Cut-off 2016, China's regenerative resource installed capacity accounts for global total amount
24%, have become world's energy-conservation and utilize new energy, the first big country of regenerative resource.
Photovoltaic generation adds up installed capacity 4318 as main new energy branch, 2015 end of the year whole nation photovoltaic generations of cut-off
Ten thousand kilowatt hours, turn into the maximum photovoltaic installed capacity country in the whole world.To improve photovoltaic panel generating efficiency, increase photovoltaic array receives
Solar radiation amount, it is necessary to adjust angle of photovoltaic panel, so that sunlight vertical irradiation photovoltaic solar panel at any time.Claw-pole permanent magnet is same
Step motor adjusts drive mechanism in real time as solar energy photovoltaic panel angle, and its continuous, reliability service is to photovoltaic plant to closing again
Will.NORTHWEST CHINA area, particularly desert area, grows by the annual sunshine-duration, and intensity is high, and luminous energy is rich main as China
Photovoltaic plant base.And sandstorm weather occurs for annual desert, Gobi Region, counted according to more photovoltaic plant staff,
The solid fine grains such as the sand that sandstorm weather is brought easily make photovoltaic panel transmission mechanism that jam occur, and easily cause claw-pole permanent magnet same
Step motor occurs stall and damages motor, while sandstorm weather at least causes 300-400 pawl of a photovoltaic plant every time

98mA, rotating speed 5r/min, power supply are single-phase 220V power supplys, artificially make claw-pole type permanent-magnetic synchronous stall, measure electricity
Machine locked rotor current is about 108mA.According to experimental result and market survey, existing claw-pole type permanent-magnetic synchronous rotation-clogging protection is deposited
In problems with：(1) at present on the market there is not yet ripe claw-pole type permanent-magnetic synchronous rotation-clogging protection device, Yi Jixiang
Pass technology report；(2) due to the specific physical structure of magneto, curent change during motor generation stall is made to compare other excitations
Type motor changes unobvious, test result indicates that motor rotation blockage is 10mA or so compared with normal operation amplification；(3) existing motor rotation blockage
Protection device is mostly directed to excitation type motor, because single-phase claw-pole type permanent-magnetic synchronous locked rotor current is smaller, can not accurately sentence
Do not go out whether claw-pole type permanent-magnetic synchronous occurs stall, existing motor rotation blockage protection is not particularly suited for single-phase claw-pole permanent magnet
Synchronous motor stall.
In summary, design a kind of claw-pole type permanent-magnetic synchronous rotation-clogging protection system can both reduce photovoltaic plant because
Economic loss caused by sandstorm, extend motor service life, and can maintains photovoltaic panel efficiency power generation, reduces photovoltaic panel driving machine
Structure manual maintenance cost, there is the important meaning in solar energy power generating field.
