LDZB6-10 indoor, single, fully enclosed, through-wall current transformer
1. Overview of LDZB6-10 indoor, single, fully enclosed, through-wall current transformer:
This type of current transformer is epoxy resin cast, single-turn, fully enclosed, wall-through structure, suitable for current, electrical energy measurement and relay protection in power systems with a rated frequency of 50HZ or 60HZ and a rated voltage of 10kv and below .
2. Use conditions of LDZB6-10 indoor, single-phase, fully enclosed, through-wall current transformer:1. The altitude does not exceed 2500 meters;2. The ambient temperature is not higher than +40℃ and not lower than -5℃;3. The relative humidity of the surrounding air is not more than 85% (20℃);4. The surface creepage distance of the product: meet the pollution level II;5. There is no gas, steam, chemical deposition, pollution and other explosive and corrosive media that seriously affect the insulation of the transformer in the installation site.3. Introduction to the structure of LDZB6-10 indoor, single-phase, fully enclosed, through-wall current transformer: This type of current transformer is a fully enclosed, wall-through structure. Divide the copper rod structure at a time. The product adopts superconducting magnetic material, so that the product can reach 0.2S high precision, and can have the characteristics of large dynamic, thermally stable current carrying capacity and small partial discharge.4. Main technical parameters:1. Rated primary current: 400-1500A;2. Rated secondary current: 5A or 1A;3. Rated voltage: 10KV;4. Measurement accuracy level: 0.2, 0.5;5. Protection accuracy level: 10P15;6. The power factor of the load: COSφ=0.8 (lagging);7. Product standard: GB1208-2006 "Current Transformer";8. At rated load, the 10% multiple is 15; Rated primary current (A) | Accuracy level combination | Rated output (VA) | Rated short-time thermal current (Ith) (kA) | Rated dynamic stability current (Idyn) (kA) |
