JSZW8-10FR type 10KV four-bucket voltage transformer is a three-phase cast insulation with fuse protection of high-voltage voltage transformer, the following are its main features and technical parameters:
Product Overview:
JSZW8-10FR type voltage transformer is suitable for 12kV and AC 50/60Hz within the outdoor column switchgear, for measuring instruments, meters, relays or other similar appliances for power measurement or relay protection use
The voltage transformer is suitable for outdoor pole-mounted switchgear within 12kV and AC 50/60Hz for measuring instruments, meters, relays or other similar appliances for power measurement or relay protection.
Technical Parameters:
Rated insulation level: 12/42/75kV.
Power factor cosΦ=0.8 (lagging).
The rated voltage ratio of model JSZW-10FR is 10/√3/0.1/√3/0.1/√3/0.1/√3/0.1, the accuracy level is 0.2/0.5/3P, the rated secondary output is 15/15/50VA, and the limit output is 300VA.
.
Structural features:
This product is a three-phase five-column anti-resonance voltage transformer, which can effectively prevent ferromagnetic resonance from burning the transformer. In the event of a 100% ground fault in the system, it can still operate normally for a long time, while the protection winding (da.dn) generates 100V to actuate the relay.
.
Conditions of use:
Ambient temperature between -5ºC and 45ºC, average daily temperature not exceeding 35ºC; Relative humidity: average daily value not exceeding 95%, average monthly value not exceeding 90%; Altitude not exceeding 1000 meters (please provide the altitude when using in high altitude areas); Installation type: indoor installation
.
Execution standard:
GB20840.3-2013 "Transformer Part 3: Supplementary Technical Requirements for Electromagnetic Voltage Transformer", JJG314-2010 "Measurement Voltage Transformer Inspection Regulations", GB311.1-2012 "Insulation Fit for High Voltage Transmission and Transformation Equipment".
.
Wiring schematic diagram:
The primary N point is directly grounded, the secondary winding (da,dn) for the relay or microcomputer monitoring and control use, this product is not allowed to repeat access to the primary deharmonization device and the secondary microcomputer deharmonization device, otherwise it will burn the PT. primary and secondary in addition to the grounding point is strictly prohibited other than the labeled grounding point, otherwise it will burn the PT.
Otherwise, it will burn PT.
JSZW8-10FR type voltage transformer with its excellent performance and reliable protection function, suitable for 10KV power distribution system, provide voltage measurement and protection signal, and can effectively inhibit the resonance overvoltage of the distribution system after different degrees of grounding.
