Cast Resin Type Transformer Nameplate Parameters

The factory nameplate of the cast resin type transformer is an important part of the safe and normal operation of the dry-type transformer. The content of the factory nameplate of the dry-type transformer is used to select the dry-type transformer as a basis to meet customer needs.

(1) Short-circuit capacity kVA: the maximum high power that the dry-type transformer can continuously output for a long time.

(2) (2) Rated current kV: the working standard voltage that the dry-type transformer can bear during long-term operation (the value of the positive and middle branch of the factory nameplate value).

(3) Rated voltage: The amount of current that the dry-type transformer allows for a long-term basis at the rated current.

(4) Volume ratio: the ratio of the short-circuit capacity of each side of the cast resin type transformer. (The short-circuit capacity of each side is not necessarily the same).

(5) Working voltage ratio: the ratio of the rated current of each side of the dry-type transformer.

(6) Characteristic impedance (or short-circuit fault) working voltage: When the secondary winding of the dry-type transformer is short-circuited, the voltage is slowly transformed on the primary winding until the short-circuit capacity of the secondary winding reaches the rated current. Released operating voltage value. indicated as a percentage of common rated current.

(7) Short-circuit fault loss (ie copper loss) kW: The output power consumed by the dry-type transformer when the secondary winding of the dry-type transformer is short-circuited and the primary winding enters the rated voltage.

(8) Full load loss (ie iron loss) kW: The loss caused by the dry-type transformer dry-type transformer core (excitation regulator and vortex) when the dry-type transformer is under the rated current and the secondary full-load (lead-out) of the dry-type transformer.

(9) Full-load current: The dry-type transformer is under the rated current, and the current of the primary winding (excitation regulator) is based on the secondary full load (lead-out). indicated as a percentage of common rated voltage.

(10) Wiring (or connection) level: a digital clock indicating method used to mark the connection order, winding direction and optical rotation of the three-phase windings on each side of the dry-type transformer and the internal connection of the working voltage of each side line.

The above is a detailed introduction to the content of the dry-type transformer factory nameplate. The main parameters of the dry-type transformer factory nameplate The maintenance and operation of dry-type transformers is very critical.
