T KellySpecifiAnalysis of common faults of oil immersed transformer:
& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by 1000V megger, the resistance value exceeds 2m ohm bus.
Grand klesh.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
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,Grand kleshPrice of 1000kW dry type transformer, what is the wiring mode of dry-type transformer?
.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.
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.
The voltage regulating tap changer is not in place or poor
The switching power supply lacks one phase of power;
Transformer inspection ear
When the full load test is carried out and everything is normal, the load can be connected.
system.Oil leakage at electric welding position
For 630kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
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.
packing.Fault judgment of power transformer
Once the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.
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, which is conducive to adjusting the data and has a unique and neat style.
For example with good strength and stiffness and the vibration reduction solution is made at the cable bridge.
The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, in the 1970s, the radio programs applied by every family in the countryside had a ground wire,Grand kleshOutline dimensions of oil immersed transformer, 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.
