Dry transformer is characterized by safety, fire prevention, pollution, can be directly installed in the load center; Maintenance-free, easy installation and low comprehensive operation cost; Good moisture-proof property, can operate normally under 100% humidity, can be put into operation without pre-drying after shutdown. Dry type transformer model is more, the meaning of the representative is not the same, the following billion electric explained dry type transformer each model meaning for you to represent the meaning.

Example: scb10-1000kva / 10KV / 0.4kv. S means that the transformer is a three-phase transformer, and if S is replaced by D, it means that the transformer is a single-phase transformer. C means that the windings of this transformer are solid formed by resin casting. B means foil winding, if R means winding, if L means aluminum winding, if Z means load regulating voltage (copper is not marked). 10 is the design number, also known as the technical number. 1000 kva represents the rated capacity of this transformer (1000 kva). 10KV means primary rated voltage, 0. 4KV means secondary rated voltage.

Power transformers are described as follows:

D S J L Z SC SG JMB YD BK(C) ddgd-single-phase s-three-phase j-oil-immersed self-cooling l-winding is aluminum wire Z- and load regulating sc-three-phase epoxy resin pouring sg-3-coherent self-cooling JMB- local lighting transformer yd-test single-phase transformer BF(C) - control transformer (C for C type iron core structure) ddg-single-phase dry low-voltage high-current transformer

Note: the digital part behind the power transformer: the rated capacity (kva) is indicated on the left side of the diagonal line; The right side of the slash indicates the primary side rated voltage (kilovolts).

For example, sjl-1000/10 is a three-phase oil-immersed self-cooling aluminum wire and two-coil power transformer with rated capacity of 1000 KVA and rated voltage of 10 KVA on the high voltage side: basic model + design serial number -- rated capacity (KVA)/ high voltage side voltage

For example, 2: s7-315/10 transformer

That is, three-phase (S) copper core 10KV transformer, capacity 315KVA, design number 7 is energy saving.

For example: 3: scr9-500/10, s11-m-100/10S - three phase C - casting (dry type transformer) r winding type 9 (11), design the serial number (100) 500 - capacity (KVA) 10 - rated voltage (KV) m - closed type: SCZ SC (B) 9 - XXXX / * * - three-phase solid molding (epoxy pouring) load B - Z - low voltage foil coil 9 - performance level code XXXX - rated capacity (KVA) * * -- high pressure rated voltage (according to the rating of fill in)

Model of transformer:

Transformer winding number + phase number + cooling mode + whether forced oil circulation + load or no load voltage regulation + design serial number + "-" + capacity + high voltage side rated voltage composition.

For example 4: sfpz9-120,000/110

It refers to the three-phase transformer (the double-winding transformer omits the winding number, and there is an S in the front if it is a three-winding transformer). The double-winding forced oil circulation air-cooled on-load voltage adjustment is designed for a transformer with the design serial number of 9, capacity of 120000KVA and rated voltage of 110KV on the high-voltage side.

For example 5: scb9-2000/10SC-- three-phase solid forming (epoxy pouring)

B---- -- low voltage foil coil

9---- -- performance level code

2000-- rated capacity

10-- rated high voltage

For example, 6: scb9-2000/0.4 ~0.23 Dyn11

This is the model of dry transformer, where S stands for three phases; C stands for epoxy resin castable insulation; B distribution transformer; 2000 is capacity KVA; 0.4-0.23kv rated line voltage and rated phase voltage on the low voltage side; Dyn11 connection means three-phase triangle connection on the primary side and star connection on the low-voltage side. The low-voltage side voltage is 11 points, that is, the low-voltage side voltage is 30 degrees ahead of the high-voltage side voltage.
