When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.
Hulgada.The common dry-type transformer is an important electrical equipment,HulgadaFunction of main transformer in power plant, and the voltage is constantly regulated. However because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation,HulgadaRanking of box transformer manufacturers, and overload is not allowed in the whole process of operation.
Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil,HulgadaPeriodic voltage regulator for maintenance of oil immersed transformer, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.
Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.
Dry type transformer
Once 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 until you find out the cause.

Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, if the second phase is blocked it shall be handled properly.

Hulgada.When the transformer is out of phase, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:
High voltage fuse of transformer breaks one phase;
A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
