Under normal conditions, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.
Coimbra.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.
When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules,CoimbraDistribution transformer maintenance, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings They also have mutual inductors between the inductors of each module, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.
Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.
On load commissioning:
What is the wiring mode of dry-type transformer?
At that time, only a few companies in China could produce 500kV high-voltage transformers,CoimbraHow much is a box transformer, and the market share of high-voltage transformers was basically monopolized by overseas leaders.
After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
Honesty is the foundation.Oil leakage of bolt or pipe external thread
Some are tied with plastic tape, and some immediately press the two edges together because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.
Oil leakage of heat pipe radiator
The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.
wholesaler.Connection group structure of dry-type transformer
The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;
The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side),CoimbraPower transformer price, and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.
Coimbra.Manufacturing process and steps of dry-type transformer
Loose core screw
The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.
