St AndreEnergyThe key reason for oil leakage is that there are defects in cast iron parts
Oil leakage of porcelain pot and laminated glass oil level gauge
St Andre.The transformer manufacturer will introduce the efficiency of the transformer to you
When the full load test is carried out and everything is normal, the load can be connected.
.The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
After tightening the loose bolts,St Andre2200 oil immersed transformer, seal the flange, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
For 630kVA power engineering transformer, plastic parts are selected in the middle of iron core,St AndreOil immersed air-cooled transformer, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
How is the quality level of dry-type transformer compared with foreign countries?
When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.
Customer first.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, it will affect the whole power circuit
The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.
Careless maintenance and insulation damage
The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock,St AndreYuxi transformer, and the phasor of the phase voltage of the secondary side is used as the second hand.
Customer first.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, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.
In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is the greater the output power is. On the contrary, it is very small.
St Andre.Connection group structure of dry-type transformer
When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.
The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source sampling date, sampling person, weather conditions and other materials of the oil sample.
