Dry type transformer
Novitravnik.Transformer
The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials,NovitravnikBox type transformer, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, that is, the disconnection component of the electric field is small.
Operation and maintenance management of oil immersed transformer
Automatic system of centrifugal fan: measure the temperature data signal according to the PT100 thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches 110 ℃, the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as 90 ℃ the system software will automatically terminate the centrifugal fan.
Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction,NovitravnikPrice of 400KVA dry type transformer, chemical enterprises and factories.
Quality documents.According to the condition of cracks,Novitravnik1000 KVA power dry-type transformer, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.
On load commissioning:
(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
What is the wiring mode of dry-type transformer?
Service first.When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
Right, 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.
Deterioration damage of transformer core insulation
Novitravnik.The switching power supply lacks one phase of power;
Operation of oil immersed transformer
Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.
