PatanOld box tOil leakage at looper flange
Before application,CampelMain parameters of oil immersed transformer, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a 105 ℃ drying oven. After refrigeration the bottle cap shall be tightly closed and cannot be opened before application.
Campel.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
Power transformer factory
.The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.
There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.
What is the reason for the shutdown of power transformer?
Seal oil leakage
How is the quality level of dry-type transformer compared with foreign countries?
The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω,CampelDistribution transformer ranking, According to Ohm's law when the insulating layer is damaged, the current is only 1 / 500 of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.
quality.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.
The hanging core of dry-type transformer is a vital part
In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?
How much is the power transformer
Test results.Solenoid insulation deterioration
During the operation of the transformer, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.
Campel.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,CampelStructure of 35 kV oil immersed transformer, please cut off the input switching power supply.
Falling foreign matters and piercing
Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
