Typical Wiring Diagram of 35kV Line Radial π Connection

When a 35kV line adopts a radial power grid structure, a single - side power supply or a double - side power supply radial type can be used according to the situation of the power supply points, and a loop - out interval is reserved at the end of the line.

Typical Wiring Diagram of 35kV Line Radial T - Connection

For double - radial lines, it is advisable to select a double - side power supply. When the power supply points do not meet the requirements, a same - side power supply can be adopted.

Typical Wiring Diagram of 35kV Line Loop - type π Connection

When the upper - level power supply points do not meet the requirements for constructing a chain - type structure, a loop - type can be used as a transition structure for the chain - type structure.

Typical Wiring Diagram of 35kV Line Chain - type π Connection

In areas with high load density such as downtown areas and urban districts, as well as areas with high requirements for power supply reliability, chain - type wiring can be adopted.

1.Causes of Damage to Agricultural H59/H61 Oil-Immersed Distribution Transformers1.1 Insulation DamageRural power supply commonly uses a 380/220V mixed system. Due to the high proportion of single-phase loads, H59/H61 oil-immersed distribution transformers often operate under significant three-phase load imbalance. In many cases, the degree of three-phase load imbalance far exceeds the limits permitted by operational regulations, causing premature aging, deterioration, and eventual failure of th

Five Common Defects of H61 Distribution Transformers1.Lead Wire DefectsInspection Method: The three-phase DC resistance imbalance rate significantly exceeds 4%, or one phase is essentially open-circuited.Remedial Measures: The core should be lifted for inspection to locate the defective area. For poor contacts, re-polish and tighten the connection. Poorly welded joints should be re-welded. If the welding surface area is insufficient, it should be enlarged. If the lead wire cross-section is inade

What Is an H61 Distribution Transformer? Uses & Setup
H61 distribution transformers refer to transformers used in power distribution systems. In a distribution system, high-voltage electricity must be converted into low-voltage electricity via transformers to supply electrical equipment in residential, commercial, and industrial facilities. The H61 distribution transformer is a type of infrastructure equipment primarily used in the following scenarios: Supplying power from high-voltage grids to low-voltage grids: During power delivery, high-voltage
