Operation of oil immersed transformer
Cabinda.The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT100 temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as 420mA analog quantity. If it is to be far away (the distance can reach 1200m, the electronic computer can be equipped with an electronic computer socket,Cabinda125 KVA dry type transformer, an intelligent transmitter, and 31 transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt100 thermistor sensor, so as to further improve the stability of the temperature maintenance system software.
If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
The manufacturing process of dry-type transformer is very process,CabindaIntroduction to dry type transformer, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.
In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ 4Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.
The switching power supply lacks one phase of power;
What is the wavelength of oil immersed transformer?
High voltage fuse of transformer breaks one phase;

Step up process of dry-type transformer?
The key reason for oil leakage is that there are defects in cast iron parts
Cabinda.Common problems of tap changer of power transformer
If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.
