Kancaampa20 kV
MahendranagaHoThe power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
Oil leakage at looper flange
Kancaampa.A kind of power engineering equipment that converts the working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering, it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss of electromagnetic energy in the whole process. Therefore, the power consumption of the processing plant is all connected with 10kV switching power supply, which is converted into bottom voltage electromagnetic energy through transformer.
Connection group structure of dry-type transformer
.Operation of oil immersed transformer
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.
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,KancaampaTransformer power transmission, it will affect the whole power circuit
After the test, connect the data signal contact of the automobile relay with the alarm circuit the pull-in contact with the opening circuit,KancaampaIntroduction to oil immersed transformer, and adjust the overcurrent protection value.
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.
(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation, a spacing of more than 2m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
resources.It will also produce many faults,KancaampaTransformer capacity of distribution room, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.
The method and whole process of taking oil sample of power transformer are as follows:
Oil immersed transformer
There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.
Inspection environment.Solenoid insulation deterioration
There is a magnetic induction line crossing in the transformer core, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.
It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.
Kancaampa.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.
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.
