Raskanod110kV 
ValevoPrice ofall anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack
After the oil is drained, the human resources traction belt shall be used as a guide.
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, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.
Raskanod.At that time, only a few companies in China could produce 500kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.
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?
.The switching power supply lacks one phase of power;
Different diversion methods dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.
Loose core screw
Several detection methods for installing transformer
Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).
total cost.The key reason for oil leakage is that there are defects in cast iron parts
Power transformer manufacturer
When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective,RaskanodCommercial power transformer, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases,RaskanodAC step-up transformer,RaskanodBox type transformer room, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.
The switching power supply lacks one phase of power;
Latest consultation.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.
Hand touch method for transformer inspection
Protective measures for damping of dry-type transformer
Raskanod.After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.
Protective measures for damping of dry-type transformer
The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.
