DAHU electrical specializes in the production of 0.5-40.5kv transformers. It has cooperated with many national power bureaus for 10 years and exported to foreign markets. If there is any quality problem within the warranty period, it can be replaced free of charge.
Product Overview:
JSZW12-10FR voltage transformer is a three-phase five column, indoor type product suitable for voltage, electrical energy, and relay protection in power systems with a rated frequency of 50Hz and a rated voltage of 10kV and below
.
Technical parameters:
This transformer is equipped with fuse protection and can provide a measurement voltage of 100V, as well as a 220V operating power supply for relay use
.
The rated voltage ratio of product model JSZW-6 is 3000/√ 3/100/√ 3/100/3, accuracy level and rated output (VA) COS φ=0.8, ultimate output (VA) is 100/600, and rated insulation level (kV) is 7.2/32/60
.
The rated voltage ratio of product model JSZW-10 is 10000/√ 3/100/√ 3/100/3, the accuracy level and rated output (VA) COS φ=0.8, the ultimate output (VA) is 100/1000, and the rated insulation level (kV) is 12/42/75
.
Structural features:
When using the JSZW12-10FR voltage transformer in the system, each group requires three castings to be placed on a three-phase five column iron core. The separation of measuring winding and protective winding effectively ensures the accuracy of measurement and the reliable function of protection
.
Application scenarios:
This transformer is suitable for installation in 12kV primary and secondary fusion ring main unit (box), used to provide voltage measurement and protection signals for 10kV distribution system, and can effectively suppress resonance overvoltage after different degrees of grounding of the distribution system
