Voltage in DC latus solaris industria ratio augetur 1500V et promotionem et applicationem 210 cellulis posuit deinceps superioris ad electrica salus totius photovoltaic ratio. Post systemate voltage augetur, opposuit challenges ad insulationem et salus system, auget periculo velit naufragii components, inverter wiring et internum culpam in opportunitate praesidio mensuras superiores segregare vitium opportune et efficaciter correspondentes vitiis fieri.
Ut sit compatible cum components cum auctus current, inverter manufacturers auget initus current de filum ex 15a ad 20a.when solvendo quaestio de 20a input current, in inverter manufacturer et aditus capability of MPPT et extenditur filum aditus facultatem MPPT ad tres vel more.in casu de culpa, in filum potest habere problema de current backfeeding. Ut solve hoc problema, a DC switch cum munus "intelligentes DC shutdown" emerged ut tempora requirere.
01 Differentia inter traditional isolatur Switch et intelligentes DC SWITCH
Primum omnium, in traditional DC isolatur SWITCH potest conteram intra rated current, ut a nominis 15a, tunc potest conteram in current sub rated voltage of 15a et wither.altho fabrica SWITCH PB , Quod plerumque non potest conteram brevi circuitu current.
Maximus differentia inter an isolatur Switch et circuitus est quod circa ruptor est facultatem ad conteram brevi circuitus current, et brevi-circuitu current in eventu de culpa est multo maior quam rated current in castris ANTOLIUM; Cum brevi circuitu Current photovoltaic DC latus plerumque circa 1.2 temporibus rated current, quidam isolaturs virgas aut onus virgas potest etiam conteram brevi circuitus current de DC latus.
At present, the smart DC switch used by the inverter, in addition to meeting the IEC60947-3 certification, also meets the overcurrent breaking capacity of a certain capacity, which can break the overcurrent fault within the nominal short-circuit current range, effectively It solvit quaestionem de filum current backfeeding. Simul dolor DC switch combined cum DSP de inverri, ut trinus unitas switch potest verius et celeriter animadverto munera ut oercurrent praesidio et brevi circuitu praesidio.

II Solaris ratio consilio vexillum postulat quod cum numerus initus canales de chordis per se MPPT est ≥3, fuse tutela debet configurari in DC Side.The commodum applicare filum inverters est usus non-fuse ad redigendum Operatio et sustentacionem opus crebris replacement fuses in DC latus. Inverters uti intelligentes DC switches pro fuses. MPPT potest input III coetibus cordis. Sub ultima culpa conditionibus, illic erit periculum quod current ex II coetibus a chordis et influunt ad I coetus a chordis. In hoc tempore, quod intelligentes DC SWITCH erit POP aperire DC switch per shunt release et disconnect in tempore. Circuit ut celeri remotionem culpae.

The shunt release is essentially a tripping coil plus a tripping device, which applies a specified voltage to the shunt tripping coil, and through actions such as electromagnetic pull-in, the DC switch actuator is tripped to open the brake, and the shunt tripping It Saepe usus est in remotis automatic potentia-off control.when in captiosus DC switch sit configuratur in Goodwe inverter, in DC SWITCH potest esse retentus et aperuit per inverter DSP ad DEJUGO et aperuit per inverter DSP ad DEJUGO DC SWITCH.
Nam inverters usura shunt iter praesidio munus, quod est prima necessarium ut imperium circuitu de shunte coil obtinet imperium potentia ante trinam praesidio munus de principalis circuitus potest praestati.
03 Application Prospectus intelligentes DC SWITCH
Ut salus photovoltaic DC latus paulatim questus magis attentio salutem munera ut AFCI et RSD sunt aeque momenti magis et recenter.smart Cum enim culpa occurs, in captiosus DC SWITCH potest efficaciter uti remote control et altiore imperium logica de dolor switch. Post AFCI vel RSD actio, DSP mittam a trinus signum ad automatice trinus DC DC Switch. Forma clarum confractus punctum ut salus sustentationem curatores. Cum a DC switch frangit magna current, quod erit afficit electrica vitae switch. Cum per quod intelligentes DC switch, in fractionis solum consumit mechanica vita de DC switch, quod efficaciter protegit electrica vitae et arcus extinguunt facultatem ad DC switch.
Et applicationem intelligentes DC Switches etiam planto fieri potest ad certo "unum-key shutdown" in inverter apparatu in domum missionibus; secundo per subitis, in DC SWITCH PB, cum emergency et DC switch potest esse celeriter Concurately clausa per DSP signum, formans certa sustentacionem Disiunctio punctum.
IV Summary
The application of intelligent DC switches mainly solves the protection problem of current backfeeding, but whether the function of remote tripping can be applied to other distributed and household scenarios to form a more reliable operation and maintenance guarantee and improve user safety in emergency situations. Et facultatem ad agam cum vitiis usque postulat applicationem et verificationem de Smart DC switches in industria.
