SW-TBZD oil-immersed grounding transformer and small resistance grounding complete set of equipment Baoding national high-tech industrial development zone, China, is the 1. product overview of electric technology co., ltd. neutral point grounding methods are generally divided into three methods: grounding transformer and resistance grounding, grounding through arc suppression coil, grounding through arc suppression cabinet. Selection of neutral point grounding mode: grounding current is greater than 120A, which is suitable for grounding via grounding transformer and resistance; Grounding current is less than 120A, which is suitable for grounding via arc suppression coil or arc suppression cabinet. This product is grounded by resistor, with low loss, low noise, low PD, low temperature rise, maintenance free and safe and reliable, its performance can reach the advanced level of similar products in China, and has been widely applied in various fields or systems. 2. product model description SW-T BZD- -on the electrical oil-immersed grounding transformer neutral point grounding resistance voltage level KV grounding current a 3. product scope of use this product is suitable for 6 ~ 66KV medium voltage distribution network. 4. environmental conditions for use Ambient temperature: upper limit 10 40 C, lower limit -30 C (indoor); Altitude: not more than 3000m; Relative humidity: daily average value is not more than 95%, monthly average value is not more than 90%, and no conductive dust exists; Earthquake intensity: not more than 8 degrees; No fire, explosives, chemical corrosive products and places with severe vibration. The 5. products constitute oil-immersed grounding transformer and small resistance cabinet grounding protection complete sets of equipment. The main components are: oil-immersed grounding transformer, resistor, current transformer, isolating switch, dry variable temperature controller, resistance cabinet intelligent controller, cabinet body and installation accessories. 6. Ordering Instructions Our company can design resistance cabinet according to customer's requirements: Is it equipped with grounding transformer? If yes, provide detailed technical parameters of grounding transformer; cabinet material, IP protection grade, outdoor/indoor type, incoming and outgoing line mode and color, etc. Whether the indoor type is a split cabinet (I. e. the grounding transformer is separated from the resistor cabinet), if it is a split cabinet, please confirm whether it is a parallel cabinet. Resistor material, rated voltage, ground current, current time.

The surface of rare earth alloy grounding material is treated by special process, and the surface corrosion product is nanometer level. The corrosion product is small and dense, which prevents harmful ions in the soil from entering the substrate through the corrosion product film to cause further corrosion, and improves the corrosion resistance of the product. The corrosion resistance of rare earth alloy is 6 times that of galvanized steel.
