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.
JSZV12-10R type voltage transformer is a 10KV indoor three-phase built-in fuse high-voltage voltage transformer, the following are its main features and technical parameters:
Performance Overview:
JSZV12-10R voltage transformer is a three-phase indoor product, suitable for rated frequency 50Hz, rated voltage 10kV and the following power system, for voltage, electrical energy and relay protection.
The product is equipped with fusing protection.
The product with fusing protection, "V" type wiring to become three-phase, can also be used as two single-phase alone.
It can also be used as two single-phase individually.
In addition to the secondary output voltage of 100V for measurement, it can also be supplied with 220V operating voltage for the power supply of the operating organization.
The secondary output voltage is 100V for measurement.
Conditions of use:
Surrounding air temperature change does not exceed -5ºC to +40ºC.
Altitude not exceeding 1000 meters.
Relative humidity not more than 80%.
Where there are no corrosive gases, vapors or deposits.
Where there is no conductive dust (carbon dust, metal dust, etc.).
Where there is no strong vibration or impact
.
Execution standard:
GB/T20840.3-2013 Electromagnetic Voltage Transformer
GB/T20840.4-2015 Combined Transformer
GB311.1-2012 "Insulation fit for high-voltage power transmission and transformation equipment".
JJG314-2010 "Measurement Voltage Transformer Testing Regulations".
.
Main technical parameters:
Rated voltage ratio: 10/0.1kV.
Accuracy level or combination of accuracy level: 0.2/0.5/3P.
Rated output (VA): 30VA/0.2 level, 80VA/0.5 level.
Limit output (VA): 800VA.
Rated insulation level: 12/42/75kV
.
Structural features:
Epoxy resin cast insulation, fully enclosed structure.
The iron core is made of high quality cold rolled silicon steel sheet, together with the primary and secondary windings cast into a whole, with excellent insulation properties and moisture-proof, anti-fouling ability.
The primary winding A, B and C phases are equipped with a circuit breaker that matches the short-circuit capacity of the transformer, effectively protecting the transformer from being burned out in the event of a grid fault. The fuse is installed inside the terminal of the primary winding, which is easy to replace.
The fuse is mounted inside the terminal of the primary winding outlet, which is easy to replace.
