Two point grounding device of iron core caused by residual welding scar;

1It should be said that after the development trend of these years, the overall level of Chinas transformer industry at this stage is basically international and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.

kPaziciaWiring mode of dry-type transformer:

After the power transformer has been used for a long time, common faults of iron core will occur. Dont worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:

ELausanne Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.

VoThe step-up dry-type transformer refers to the instantaneous operation of voltage. At this stage,Products Show there are few manufacturers of dry-type transformer that can reasonably guarantee the instantaneous step-up in China. The step-up dry-type transformer has strong step-up capacity and good practical effect. The difference depends on that the transformer power switch without excitation regulator does not have the ability to change gear with load. Because this kind of tap power switch can cut off the whole process in a short time during the whole process of gear change,Alot NangoScb11 three-phase distribution dry-type transformerWhat is the price of cutting off the load current will cause arc burning between circuit breakers, tap power on and off or short circuit fault, so the dry-type transformer shall be powered off during regulation. Therefore, it is generally used as a dry-type transformer that is not very strict in voltage regulation and does not need to be adjusted frequently.

The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.

It can be seen from the above that from the perspective of power saving, in some cases transformers & ldquo; A small horse pulls a small car & rdquo; Cant compare with & ldquo; Middle car & rdquo;, Even less than & ldquo; Great Lars, little dragons & rdquo;,Products Show Therefore, the loss of transformer full load and load must be considered in the calculation, and the results can be properly made in terms of power saving or power consumption. According to the correlation between the load rate and the transformer capacity: . The transformer load rate and power saving will be brought into the formula: the load index of the transformer, that is, the operating load and rated capacity of the transformer . Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P, and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer, that is, the formula: Subtraction formula is used to calculate the detailed formula for saving transformer output power: when the transformer operation loss is small and the rate is large, the load index is the load index, and when the specific copper loss is equivalent to iron loss,Products Show the rate is large.

kTurn off the gate valves (butterfly valves) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank body, appropriate surface treatment shall be carried out,Alot NangoScb11 three-phase distribution dry-type transformerWhat is the price of and then Fushi blue raw materials shall be selected for sealing treatment.

ZThe iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer according to the magnetic induction line of the transformer ferrite core, its orientation and size change, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.

JInstallation conditionsOnce the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts with overtemperature until you find out the cause.

bHMany people probably dont know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period,Power transformer price: 1000KVA, 33kV, 25kV, power transformer, oil immersed transformer, dry-type transformer factory you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.

The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year;

The insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;

Application processpThe iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change, which promotes the internal molecular structure of the ferrite core to rub against each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.

WAfter no-load test run is normal for h, and the load shall be gradually increased from %, % and % by grade.

Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.

rBMaintenance contents of power transformer

There is a magnetic induction line crossing in the transformer core, which will cause induced electromotive force on the plan perpendicular to the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.
