Product Introduction
Main features:
1. The GTXGN-12 solid insulation fully enclosed medium-voltage switchgear has various schemes including circuit breaker line protection, transformer protection, load control, fuse combined electrical apparatus PT power supply, bus tie boosting, distribution transformer, etc. It provides a series of solutions for the upgrading and transformation of the power grid and the distribution users. The intelligent terminal base combination is configured to meet the requirements of the smart grid. This product can be used as a ring network distribution equipment for the power system, or as a distribution equipment for industrial and mining enterprises and urban construction, featuring multi-functionality and versatility.
2. The solid insulation fully enclosed switchgear uses solid insulation materials as the main insulation medium. The vacuum interrupter chamber and conductive connection, disconnect switch, grounding switch, main busbar, branch busbar and other main conductive circuits are combined into a single or combined form and encapsulated with solid insulation materials to form one or several modules with certain functions, which can be recombined or expanded, and have full insulation and full sealing performance. The surface of the accessible module is coated with conductive or semiconductive shielding layer and directly grounded for ring network cabinets.
3. All are contact-type single-person accessible main circuit modules. The surface of the module can be equipped with grounding grids and coated with conductive shielding layer and directly grounded to eliminate risks during invalid maintenance, ensuring absolute safety for users during operation and maintenance.
4. Busbar connection - All adopt rectangular copper busbar solid insulation technology. After being installed in the cabinet, it is directly installed at the upper end of the main circuit on the cabinet top, which is simple and convenient.
5. New insulation material - It adopts the alloy synthesis process of Shanghai Xiongrun's new insulation material flame-retardant ring hydrogen rubber + rubber particles + silica spherical particles + silica strip-shaped particles + silica micro powder + shielding mesh.
6. Medium-voltage system is fully protected - It is protected from adverse environmental influences (pollution, corrosive gases, condensation, humidity, dust, etc.). It significantly reduces the possibility of arc occurrence.
7. Solid insulation technology - No SF6 gas insulation, no greenhouse gases, absolutely environmentally friendly.
8. Modular design - Circuit breakers, three-position grounding isolating switches with grounding devices, cable side grounding switch outgoing line are integrated with small volume, compact structure, convenient operation and maintenance.
9. Expansion and renovation - It can implement various changes and combinations for expansion on-site.
