The picture shows the nameplate of a pad mounted transformer sold by Daelim to the United States.
What information content and key performance parameters of the transformer can be seen from the factory nameplate?
From the factory nameplate in the picture, you can see the product specifications, short-circuit capacity, rated current, rated frequency and number of phases, connection group model, cooling method, application standard, characteristic impedance working voltage, insulation level, etc. of the pad mounted transformer.
The basic parameters of the factory nameplate of the pad mounted transformer are introduced in detail below.
The product specification of the pad mounted transformer in the picture is Three phase loop pad mounted type.
This pad mounted transformer is a three-phase transformer.
Loop refers to Internal Loadbreak Switches as Loop-Feed Switches or Loop-Radial Switchese.
The volume of the transformer in the figure is 2500kVA, and the volume levels of the transformer are 630, 800, 1000, 1250, 1600, 2000, 2500, 3000, 3500kVA, etc.
The oil volume of the Pad mounted transformer is: 2100L
The rated frequency of the power supply system in my country is 60Hz.
The rated frequency in the figure is 60Hz, and the number of phases is three-phase.
Generally, a three-phase transformer is selected, unless the single-phase electrical load accounts for a very large proportion of the load.
In order to better reduce the three-phase unbalance, a three-phase transformer is independently set to supply the single-phase electrical load power supply system.
The rated current of the Pad mounted transformer in the figure is 24940DELTA X 12470 DELTA V on the high-voltage side, and the rated current on the low-voltage side is: 4160Y/2400V.
It shows that the tap switch on the high-voltage side of the transformer has three parts, and the rated current on the low-voltage side is 4160Y/2400V.
The current is 4160Y/2400V.
The purpose of setting the tap power switch on the high-voltage side of the transformer is to adjust the working voltage level of the power supply system of the transformer.
If the DC voltage of the machinery and equipment is high, change the tap power switch to 5% of the tap connector to reduce the DC voltage of the machinery and equipment;
If the DC voltage of the machinery and equipment is slightly lower, change the tap power switch to to -5% of the sub-connector to increase the DC voltage of the machine equipment.
The connection group model of the Pad mounted transformer in the picture is DELTA-Y-SWITCH. Dyn11 wiring and yyn0 wiring distribution transformer comparison.
The full load loss and load loss of the former one are slightly larger than the latter one.
The former has a slightly higher compressive strength for the primary side winding of the insulating layer than the latter.
At present, there are more and more electronic products in the load, which will cause environmental pollution of high-order harmonics to the power grid.
Compared with Dyn11 wiring and yyn0 wiring distribution transformer, when the primary winding is connected into a three-phase shape, it can make the third and non-negative integer high-order harmonics generate electric field, so the former one is beneficial to the protection of the superior power grid for the third and non-negative integers. higher harmonics;
The zero-sequence characteristic impedance of Dyn11 wiring is much smaller than that of yyn0 wiring, so the former one is beneficial to the removal of common faults of single-phase grounding;
yyn0 wiring transformer stipulates that the low-voltage neutral point current does not exceed 25% of the rated voltage of the low-voltage winding.
The low-voltage neutral point current of the Dyn11 wiring transformer is allowed to be more than 75% of the rated voltage of the low-voltage winding.
Therefore, Dyn11 wiring transformer is beneficial to improve the working ability of single-phase power imbalance.
The cooling method of the Pad mounted transformer in the picture is ONAN, which indicates the over-temperature protection method of the Pad mounted transformer.
There are also oil-to-air cooling (ONAF), oil immersion cooling (ODWF), and forced oil circulation system cooling (ODAF) for Pad mounted transformer cooling methods.
The picture shows the outdoor Pad transformer mounted.
Under normal circumstances, the outdoor is an oil-transformer transformer, and the indoor is an oil-immersed transformer.
Other information content also includes the net weight of the transformer, the information content of the manufacturer.
High-pressure side 2500/10/1.732=144A
Low-pressure side 2500/0.4/1.732=3608A
A 2500 kVA transformer can withstand up to 2700KW.
If the power factor is 0.9, it can be rated to carry an active load of 2250kW.
However, the transformer has the capability of short-circuit emergency overload.
Generally, it can carry a 20% emergency overload, and can withstand a maximum of 2700KW, but it does not exceed 2 hours. Two hours is the limit of the transformer.
If the temperature of the transformer is too high for more than two hours, the insulation will be damaged, and serious consequences such as insulation breakdown and short circuit will occur.
The method for determining the rated capacity of the high and low voltage sides of the transformer is as follows:
The transformer capacity should be selected according to the calculated load.
For a single transformer that supplies power with a stable load, the load rate is generally about 85%.
Namely: β=S/Se In the formula:
S——calculated load capacity (kVA);
Se——transformer capacity (kVA);
β——load rate (usually 80% to 90%).
Add the load power of each phase of A-phase, B-phase and C-phase independently.
For example, the total power of the A-phase load is 10kW, the total power of the B-phase load is 9kW, and the total power of the C-phase load is 11kW, and the maximum value is 11kW.
(Note: The power of each single-phase device is calculated according to the maximum value on the nameplate, and the three-phase device power is divided by 3, which is equal to the power of each phase of this device)
For example:
C-phase load total power = (computer 300W X10 units) + (air conditioner 2kW X4 units) = 11kW
11kW X 3-phase = 33KW (transformer three-phase total power)
The three-phase total power/0.8 is the most important step.
Currently, more than 90% of the transformers on the market have a power factor of 0.8, so it needs to be divided by the power factor of 0.8.
33KW / 0.8 = 41.25kW (total transformer power)
41.25KW / 0.85 = 48.529KW (transformer power that needs to be purchased), then you can choose a 50kVA transformer when purchasing.
Determine the total amount of oil that the transformer body should have according to the transformer nameplate.
Generally speaking, the amount of transformer oil is proportional to the rated capacity of the transformer.
The larger the rated capacity, the larger the transformer oil volume.
However, the specific oil volume of the transformer is related to the voltage, manufacturer, and external dimensions of the transformer.
Transformers with the same rated capacity have different oil volumes.
Oil-immersed transformer equipment uses oil as the main insulation method for transformers.
It is used for the connection between two-level power grids and between two regional power grids. The windings of oil-immersed transformer equipment are immersed in transformer oil, and the insulating medium is oil. Generally, it will be identified by the oil level indicator of the oil pillow. Generally, a large power transformer will have a pointer to display the oil level.
Of course, the oil level will also change with the oil temperature, as long as it conforms to the relevant curve.
A 2500 kVA transformer can withstand up to 2700KW.
If the power factor is 0.9, it can be rated to carry an active load of 2250kW.
However, the transformer has the capability of short-circuit emergency overload. Generally, it can carry a 20% emergency overload, and can withstand a maximum of 2700KW, but it does not exceed 2 hours.
Two hours is the limit of the transformer.
If the temperature of the transformer is too high for more than two hours, the insulation will be damaged, and serious consequences such as insulation breakdown and short circuit will occur.
The output power of the transformer is the apparent power, and the relationship with the active power (KW) is: apparent power = active power × power factor.
Calculated with an average power factor of 0.8, a 2500KVA transformer can provide (2500KVA×0.8) 2000KW of active power for the load.
The price of the transformer is mainly affected by four aspects, model, material, voltage level, capacity, of course, except for special requirements.
