12kv Medium Voltage Switchgear,Intelligent Electrical Solid Insulated switchgear Cabinet,RMU
 
Overview
 
Ang solid insulated switchgear ay isang ganap na naka-insulate at sealed na environmental protection device. Ang mga live parts ay naka-seal sa epoxy resin insulation cylinder, ang outer surface ay may coating ng grounding shielding layer, at ang silicon rubber ay nagseal sa bus. Ginagamit ang plug-in solid insulation busbar upang mag-ugnay ng dalawang adjacent na switchgears. Ang buong switchgear ay hindi naapektuhan ng external environment.
 
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 suitable para sa three-phase AC 10kV, 50Hz single bus system, ginagamit para sa pagtanggap at distribution ng energy equipment. Mayroon itong mga function tulad ng circuit control, protection, supervision, at communication. Ito ay suitable para sa airports, subways, malalaking buildings, secondary substations, at industrial and mining enterprises, etc. Ito ay lalo na suitable para sa mga lugar na may narrow space, harsh environment, mataas na altitude, at maintenance-free.
 
Feature
 
 
 - Intelligent monitoring and remote operation and maintenance: Nakakamit ng built-in IoT sensors at intelligent terminals, kung saan ito ay nagsasama 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, na binabawasan ang cost ng manual inspection at pinapataas ang operational efficiency. 
- Adaptive protection and linkage control: Ito ay may intelligent logic judgment functions, na maaaring automatikong i-adjust ang protection parameters batay sa mga pagbabago sa load ng power distribution system, na nagbibigay ng mabilis na pag-identify at isolation ng mga fault tulad ng overcurrent, short circuit, at grounding. Ito ay sumusuporta sa linkage sa substation automation systems at energy management platforms upang makabuo ng intelligent power distribution network at matiyak ang continuity ng power supply. 
- Solid insulation and environmental safety: Gumagamit ng epoxy resin integrated solid insulation technology upang palitan ang traditional gas insulation, na inalis ang risk ng pag-leak ng SF₆ greenhouse gas. Kombinado ng all-metal enclosed structure, ito ay epektibong nagsh-shield ng electromagnetic interference, adapts sa complex indoor environments tulad ng humidity at dust, at sumasang-ayon sa mga requirement ng green power grids at safety specifications. 
- Modular design and flexible expansion: Ang cabinet ay gumagamit ng modular assembly, at ang mga switch units, intelligent modules, communication interfaces, etc., ay maaaring palitan o i-upgrade nang independent. Ito ay sumusuporta sa multiple wiring methods tulad ng ring network at radial type, at nag-reserve ng expansion interfaces para sa 5G, edge computing, etc., na nagpapahusay sa later access ng new energy at energy storage equipment, at adapts sa mga pangangailangan ng smart parks, Industry 4.0, at iba pang scenarios. 
- Whole-life-cycle data traceability: Ang built-in storage chip ay nagrerecord ng whole-life-cycle data tulad ng factory parameters, operation history, at maintenance records. Kombinado ng blockchain technology, ito ay matitiyak na ang data ay hindi maaaring ma-tamper, na nagbibigay ng reliable basis para sa equipment maintenance, life evaluation, at fault traceability, at binabawasan ang whole-life-cycle management cost. 
- Human-computer interaction and safety protection: Nakakamit ng high-definition touch screen at sound-light alarm system, na intuitively nagdisplay 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 nag-push ng maintenance suggestions, na nagpapataas ng operational safety at convenience.
