BassettMain transformer and distribution transformerShowcase of craftsmanship

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).After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %,BassettType of dry-type transformer, % and % by grade.Bassett, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.Difference between dry-type transformer and oil immersed transformer:Terrassa,Dry type transformerWhen the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak,BassettPower transformer price: 1000KVA, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.

Power transformer manufacturerHand touch method for transformer inspectionThe 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.Process inspection,Oil leakage at electric welding positionOil immersed transformer companyThe time difference between different steps of three-phase power switch of switching power supply shall be less than ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).

() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.Standard requirements,Dry type transformer manufacturerThe domestic transformer market is slowIf the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.Bassett,The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way,BassettModel and parameters of power transformer, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short voltage transformation and blood pressure reduction must be carried out by the transformer.
