1 Rêbazên Amûrkarî yên Şema
1.1 Dabikin Baxbûna û Taniyê

Pêşnîyar derketina kabinên taybetkirî yên şexsî yên prefabricated, dibe ku xwe baxbûne û taniyê tevahî ye. Divê li ser mafeyên kêrkariya herêmî, mezîn û wekheviya çêrkirina nîşan bikin, sîsteman derdorên hêzîn degerandînin, projeyên plan bikin, kevankirina îmkanên bingehîn bigihînin û ritma çêrkiriyê biceribin. Her du di dema wê de, divê biha cost kontrol bikebin da ku proje nekocike.

1.2 Pêşkeftina Zeviya Structurî

Li dema pêşkeftina, hewce ye ku optimizasyon ên dimensional dibike. Design û çêrkirina divê li ser amûrkarî û karûbariyan taraz bike û berfikirina innovatif bike. Kabinetan ya substationên pre-installed destûrên welded integrated bikin. Underframe, framework, vekirina anti-corrosion dikarin da ku bi dirêjêyî daye; struktura double-layer + heat insulation temperature kontrol bike, û polyurethane insulation û six-degree anti-corrosion process ji bo zêdetkirina performansê yar bike. Wêneka anti-corrosion li Figure 1 nîşan dida.

Kabinet li ser shell ên steel ên cold-rolled steel bikar hatî, ku mezinahiya mekanîkî dest be. Berî top load 2500N/m² e; divê li ser energy ên mechanical impact ên external 20J daye, û protection level ya taybet hatî ya IK10 li GB/T 20138 nîşan dida. Li dema wê de, divê li ser requirements ên seismic ên acceleration ên horizontal 0.3 (g) û acceleration ên vertical 0.15 (g) daye, û report ên seismic hatî ji Institute of Engineering Mechanics, China Earthquake Administration hate werin.

1.3 Optimizasyon ên Environment ên Control ên Navendî

Modular intelligent prefabricated cabin substations, lê girêdayî pir zelalî heye, hewce ye ku environment ên control ên navendî bikin. Navenda model ên control ên sahantîn bikin: performansa control functions zêde bike, risks predikt bike û riske hilase bike, û li ser habits ên operators adapt bike da ku feedback ên system piştî.

Mînak, structure "double-layer metal plates + single-layer metal decorative panels" bikar hatî, refrigerator-style insulation technology bikar hatî da ku polyurethane foam filling hate werin, û thermal-break insulation li doors/windows (li Figure 2 nîşan dida) bikin, environment di physical level de optimizasî.

Li dema wê de, li ser climate û environment, di areas ên harsh de (heavy wind-sand, extreme cold, high pollution), kabinên prefabricated micro-positive pressure dust-prevention tech bikin. Pressure ên kabin li 1.05×external pressure re were, da ku dust, moisture, û condensation prevent bike, stability ên equipment garant bike.

Micro-positive pressure AC micro-positive pressure û air-conditioning systems integre bike. Clean air li cabins ên sealed hatî, da ku pressure ên navendî li pressuren external werger be; air li gaps ên door/window re tiştî, û dust block bike û environment ên dust-free yar bike. AC temperature û humidity li constancy re kontrol bike. Di low temperatures ên winter de, as industrial AC, -30 °C re start bike, û electric auxiliary heating û good thermal insulation ên kabin, environment ên navendî operating suitable maintain bike.

1.4 Improving Design Details

Modular intelligent prefabricated cabin substations functions optimize via detail design, use materials complying with regulations, and deliver remarkable benefits.

(1) Sisteman Lighting
Explosion-proof LED corridor lights are installed in the inspection corridor, with self-starting emergency lights at both ends for power-off scenarios. Inspection lights are set in unit cabinets, with switches on the operation panel.

(2) Busbars & Cables
For busbars penetrating the cabin top, non-magnetic materials (stainless steel/aluminum) are used for clamps, door panels/frames to avoid eddy currents. Primary and secondary cables are laid independently in sealed channels: The primary channel uses double-layered galvanized sheets + aluminum silicate insulation (Class A fire resistance), matching cable layout. The secondary uses metal trunking, considering anti-interference and shielding.

(3) Settlement Response
Settlement easily damages high-current hard busbars. Thus, fully insulated segmented solid busbars are adopted. Wiring reserves soft-connection nodes and stress-relief bends to compensate for tension and maintain insulation.

1.5 Innovating Maintenance Mechanisms

The operation and maintenance mode should match modular features and cabin functions, ensuring safety, stability, and quick fault removal for upgrades.

1.5.1 Guardrails and Cabin Access Ladders

For multi-level substation construction, protective guardrails are installed around the second-floor cabin. Specifications of the cabin access ladder: The steps are flush with the base of the guardrails; the steps are grid-type （slope > 55°, width < 250mm, height difference between steps > 300mm ）, and handrails are equipped on both sides (see Figure 3).

1.5.2 Reserved Test Openings for Cabinet Equipment

Cabinet-type equipment reserves test openings for test tooling installation and voltage-withstand tests. Daily inspection/maintenance uses the internal corridor (width ≥ 1200mm); during repairs, open the opposite inspection door. An emergency escape platform is installed – personnel evacuate to it and slide down in emergencies.

With reserved intervals, cabinet design leaves space for GIS expansion (considering reliability/ease). The top cover splits into 4 modules. For expansion, remove relevant covers, hoist expanded GIS into the cabinet, and assemble.

2 Development Trends

Modular intelligent prefabricated cabin substations need innovative development: The control system integrates intelligent, automation, and big-data technologies to break through the limitations of traditional control, accurately locate and resolve faults; strengthen safety protection, identify external impacts (e.g., lightning protection), and improve drills for extreme disasters.

3 Conclusion

Modular intelligent prefabricated cabin substations can solve problems of traditional construction and support long-term optimization. In the future, the technical system needs to be improved, integrating construction technologies, equipment, and management; during promotion, connect with existing power projects and systems to achieve sustainable development.
