SuharDry type 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 we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
Montes Claros.Right, as & ldquo; Great Lars car & rdquo;,Montes ClarosParameters of 500 KVA oil immersed transformer, After replacing one 255kva small transformer the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table 1. Table 1 evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly, the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer, It actually consumes electromagnetic energy.
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.
.Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, 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.
Dry type transformer
Wiring mode of dry-type transformer:
The main reason is that the welding quality of electric welding is poor, there are empty welding, needle holes, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.
The insulation of the through core anchor bolt clamping the iron core is damaged,Montes ClarosOil immersed transformer oil storage tank, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;
Power transformer manufacturer
total cost.The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, 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.
Noise solution of dry-type transformer
What is the wavelength of oil immersed transformer?
Discount.The main reason is that the welding quality of electric welding is poor there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.
The person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors, the cost of energy-saving transformers is significantly higher than that of traditional transformers, and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers, the market has not yet fully operated.

For the installation of lightning rod,Montes ClarosPrinciple of power transformer, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.
When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).
