That beadWhat 
ArmstrongThreeand then take the oil sample.
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
That bead.Accurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference 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, it is a common fault of the winding. Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.
Equipped with a temperature controller platinum thermistor (pt10) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.
.Sound in case of phase failure
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,That beadRecycling of old box transformer, in the installation and use process of lightning rod, 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 heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.
Careless maintenance and insulation damage
The person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors,That beadProtection of oil immersed transformer, the cost of energy-saving transformers is significantly higher than that of traditional transformers, and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers, the market has not yet fully operated.
Noise pollution control and prevention measures of dry-type transformer
Discount.The voltage regulating tap changer is not in place or poor
During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.

Oil immersed transformer
Where can I find it?.When leaving the factory, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than 0.2m.
That bead.Operation of oil immersed transformer
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.
For example, in the 1970s,That beadOil immersed regulator manufacturer, 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.
