GTDXF囗-12 AC metal solid insulated ring main switchgear
AC metal solid insulated ring main switchgear is a fully insulated, fully sealed, and maintenance free solid insulated vacuum switchgear. All high-voltage live parts are cast with epoxy resin material with excellent insulation performance, organically combining the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. into a whole, and the functional units are connected through fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, ensuring the reliability of equipment operation and the safety of operators. This ring main unit has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz, 12 kV power systems and widely used in industrial and civil cable ring networks and distribution network terminal projects. It is used for the reception and distribution of electrical energy, especially for urban residential distribution, small substations, switch stations, cable branch boxes, box type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, sports stadiums, railways, tunnels and other places. Due to its advantages of full insulation, full sealing, and full shielding, this product is particularly suitable for use in harsh environments such as high altitude, high temperature, humid heat, severe cold, and serious pollution.

Dry-Type Transformer Series
Category：
- Product Description
-
Note: 1. ZSCB series dry-type rectifier transformer
2. ZQSCB series dry-type traction rectifier transformer
3. Z--"Rectifier", Q--"Traction"
Performance Characteristics
- For the 12-pulse rectifier transformer, the high-voltage coils are connected in parallel, and the low-voltage coils adopt d/connection modes respectively to provide separate rectified power, forming a 12-pulse rectifier transformer.
- For the 24-pulse rectifier transformer bank, after phase shifting the high-voltage windings of two 12-pulse rectifier transformers to the left and right, the phase difference of 30° between their respective low-voltage double-split windings (d-connection) and low-voltage double-split windings (y-connection) ultimately forms phases of +22.5°, +7.5°, -7.5°, and -22.5°. Consequently, the low-voltage side outputs a 12-phase, 24-pulse voltage.
- The 12-pulse rectifier transformer can effectively suppress or eliminate high-order harmonics up to the 11th order; the 24-pulse rectifier transformer can effectively suppress or eliminate high-order harmonics up to the 23rd order, making it the mainstream rectification solution currently.
- The 24-pulse rectifier transformer is not only suitable for industrial equipment rectification but also applicable as a traction rectifier transformer for rail transit.
Application Range
The Z(Q)SCB口 series rectifier (traction) dry-type transformers are used in the electrochemical industry, steel mills, large-scale DC transmission power supplies, rail transit, power plants, and power distribution locations where AC voltage supply systems need to be changed.
