AdineType of dry-type transformerHow to define the future development direction

Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.

What is the important role of power transformer

Adine.At that time only a few companies in China could produce 500kV high-voltage transformers, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire when the oil immersed transformer fails and the market share of high-voltage transformers was basically monopolized by overseas leaders.

If the oil immersed transformer is burned by the cover of the transformer, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.

.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, etc. with flexible connection, 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.

Power transformer

The switching power supply lacks one phase of power;

The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.

Power transformer

Highly recommended.In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, and the oil sample for simplified experiment shall not be less than 1kg.

Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.

When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:

If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear 4 round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for 100mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal,AdineTransformer three-phase transformer, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.

Fair price.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than 150kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds 150kV, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
