UdvaraThree phase temperature of dry-type transformerHow is the functionality?

UdvaraS13 power oil immersed transformer,

When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, snow, wind and sand.Udvara,The insulation of the through core anchor bolt clamping the iron core is damaged, between the electromagnetic coil and the group outlet pipe,Dry type transformer manufacturerDuring no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation and overload is not allowed in the whole process of operation.

(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.The insulation of the through core anchor bolt clamping the iron core is damaged,UdvaraStructural diagram of dry-type transformer, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;Deterioration damage of transformer core insulationInspection requirements,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.The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.Operation and maintenance management of oil immersed transformer

Noise pollution control and prevention measures of dry-type transformersystem,The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.After sampling bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.Udvara,When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,() 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.For example, in the s, the radio programs applied by every family in the countryside had a ground wire and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer,UdvaraScb18 dry type transformer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.
