12kv Medium Voltage Switchgear,Intelligent Electrical Solid Insulated switchgear Cabinet,RMU
Panonood
Ang solid insulated switchgear ay isang ganap na napinsala at naseal na device para sa pangangalaga ng kapaligiran. Ang mga live parts ay naseal sa isang epoxy resin insulation cylinder, ang ibabaw ay may coating na grounding shielding layer, at ang silicon rubber ang nagseal sa bus. Ginagamit ang plug-in solid insulation busbar upang kumonekta sa dalawang magkatabing switchgears. Ang buong switchgear ay hindi naapektuhan ng panlabas na kapaligiran.
Ang solid insulation switch cabinet ay binubuo ng vacuum load switch cabinet, vacuum load switch fuse combination equipment cabinet at vacuum circuit breaker cabinet. Ito ay angkop para sa three-phase AC 10kV, 50Hz single bus system, ginagamit para sa pagtanggap at pagdistribute ng energy equipment. Mayroon itong mga function ng circuit control, protection, supervision at communication. Ito ay angkop para sa mga paliparan, subway, malalaking gusali, secondary substations at industriya at mining enterprises, atbp. Ito ay lalo na angkop para sa mga lugar na may maliit na espasyo, mahirap na kapaligiran, mataas na altitude at walang maintenance.
Karakteristik
Intelligent monitoring at remote operation and maintenance: Nakakamit ng built-in IoT sensors at intelligent terminals, ito ay nakakalikom ng real-time operating data tulad ng current, voltage, temperature, at insulation status. Inaasahan ang remote monitoring, fault early warning, at data analysis sa pamamagitan ng cloud platform, na sumusuporta sa remote operation via mobile APP o PC terminal, bawasan ang cost ng manual inspection at pataasin ang efficiency ng operation and maintenance.
Adaptive protection at linkage control: Mayroon itong intelligent logic judgment functions, na maaaring automatikal na i-adjust ang protection parameters batay sa mga pagbabago sa load ng power distribution system, inaasahan ang mabilis na pag-identify at isolation ng mga fault tulad ng overcurrent, short circuit, at grounding. Sumusuporta ito sa linkage sa substation automation systems at energy management platforms upang makabuo ng intelligent power distribution network at tiyakin ang patuloy na supply ng kuryente.
Solid insulation at environmental safety: Gumagamit ng epoxy resin integrated solid insulation technology upang palitan ang traditional gas insulation, ito ay nagwawala ng panganib ng pag-leak ng SF₆ greenhouse gas. Kombinado sa all-metal enclosed structure, ito ay epektibong nagbibigay ng shield sa electromagnetic interference, adapts sa complex indoor environments tulad ng humidity at dust, at sumasapat sa requirements ng green power grids at safety specifications.
Modular design at flexible expansion: Ang cabinet ay gumagamit ng modular assembly, at ang mga switch units, intelligent modules, communication interfaces, atbp., ay maaaring palitan o i-upgrade nang independent. Sumusuporta ito sa multiple wiring methods tulad ng ring network at radial type, at may reserved expansion interfaces para sa 5G, edge computing, atbp., na nagpapadali sa later access ng new energy at energy storage equipment, at adapts sa needs ng smart parks, Industry 4.0 atbp.
Buong-buhay na data traceability: May built-in storage chip na narecord ang buong-buhay na data tulad ng factory parameters, operation history, at maintenance records. Kombinado sa blockchain technology, ito ay nagtiyak na hindi maaaring ma-alter ang data, nagbibigay ng reliable basis para sa equipment maintenance, life evaluation, at fault traceability, at bawasan ang buong-buhay na management cost.
Human-computer interaction at safety protection: Nakakamit ng high-definition touch screen at sound-light alarm system, ito ay diretso at intuitive na nagpapakita ng equipment status at operation guidelines. Ito ay nagintegrate ng mga function tulad ng fingerprint recognition at anti-misoperation interlocking upang mahigpit na i-restrict ang unauthorized operations, at sumusuporta sa fault self-diagnosis at nagpoprovide ng maintenance suggestions, pataasin ang operational safety at convenience.
