BitolaTransformer 2000 KVAPrecautions for purchase

Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

Bitola.The efficiency of transformer is closely related to the output power level of transformer. Generally, the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power, the lower the efficiency.

It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault,BitolaParameters of 1000 KVA oil immersed transformer, and short-circuit fault is more general.

.Dry type transformer manufacturer

What about oil immersed transformer fire?

Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.

In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, there must be a strong line breaking component,BitolaWhich is better for dry-type transformer, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.

After the test, connect the data signal contact of the automobile relay with the alarm circuit,BitolaPower transformer ranking, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.

When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,

Inspection basis.Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.

Transformer is

After no-load test run is normal for 24h, it can be transferred to on-load operation, 50% and 75% by grade.

Bitola.The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.

For 630kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
