Main structure of dry type 5kVA AC hipot test set
Core: Made of high-quality cold-rolled silicon steel sheets to reduce iron loss.
High voltage coil: It is the core part of the transformer, which is wound with high-strength enameled wire and poured with epoxy resin in a vacuum environment as a whole. This makes it a sturdy, sealed whole with good electrical performance and mechanical strength, effectively preventing moisture and pollution.
Low voltage coil: also cast with epoxy resin.
Shell and accessories: usually equipped with metal or insulating materials, high-voltage output terminals, low-voltage input terminals, grounding terminals, and wheels that are easy to move.
Core Characteristics and Advantages
1.Safe, Environmentally Friendly, and Fire Risk Free:
This is the most significant advantage. As no insulating oil is used, dry type 5kVA AC hipot test set completely eliminates the risks of oil leakage and flammable oil fires, making it particularly suitable for indoor use, tunnels, subways, and other locations with strict fire safety requirements.
2.Maintenance-Free:
Unlike oil-immersed transformers which require regular checks of oil level and quality, as well as filtering and replenishment, the dry type 5kVA AC hipot test set is a solid-cast unit. This design requires no internal maintenance, significantly reducing maintenance costs and labor.
3.Lightweight, Compact, and Highly Portable:
The high insulation strength of epoxy resin allows for reduced insulation distances, leading to a more compact structure. Combined with the absence of heavy insulating oil, the overall weight and volume are much smaller than equivalent oil-immersed transformers, making them easy to move and set up on-site.
4.Excellent Resistance to Pollution and Moisture:
The epoxy resin casting effectively seals the core and windings, protecting them from moisture, dust, and chemical contaminants in the air. This ensures stable operation in relatively harsh environments.
5.Simple Operation and Clear Connections:
The simple structure and clearly exposed terminals make it easy for operators to connect quickly and efficiently.
