Rusendal30 KVAWhen 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.
Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.
Izki.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.
In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
.Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.

The method and whole process of taking oil sample of power transformer are as follows:
How much is the power transformer
The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by 100kW motor, so the usual load is 200 KW, CST = 0. One 750kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only 34%
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut),IzkiDistribution transformer capacity,IzkiWind power box transformer, wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.

Free consultation.Analysis of common faults of oil immersed transformer:
Right, as & ldquo; Great Lars car & rdquo;, After replacing one 255kva small transformer, the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table 1. Table 1 evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly, the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer,IzkiOil immersed transformer 1600KVA, It actually consumes electromagnetic energy.
After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, if the oil immersed transformer catches fire, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.
The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
