Description
The JLSW3-35KV Oil-Immersed combined transformer (also known as a metering tank) , is a type of outdoor power measuring device. It consists of three sets of single-phase wholly insulated voltage transformers configured in a three-phase Y/Y wiring scheme, with three current transformers separately connected to A, B, and C phases.
This Combined Transformer is an advanced product based on earlier designs. The addition of a moisture-proof device to the oil tank cover effectively prevents external humidity from entering, significantly extending its service life. Compared to previous designs, it features increased capacity, reduced size and weight, and enhanced ease of installation.
Designed for outdoor circuits operating at AC50-60Hz and rated voltages of 35kV or lower, this transformer is suitable for current, voltage, and energy metering applications. It is widely used in rural outdoor substations, compact transformer stations, and industrial substations. The addition of active and reactive energy meters further enhances its functionality, making it a versatile high-voltage metering solution.
