YamPower station transformerThe improvement effect of the pattern

The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong so that the bolts are not tightened well, resulting in oil leakage.Yam,The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, deformation, loosening cracking, ignition smoke, oil leakage, broken strand disconnection,YamPower supply transformer, short-circuit fault marks, hanging of dirty things, etching and turbidity, which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.Dry type transformer factoryEwarton,For no-load impulse closing of transformer, pay attention to the following matters:The flange surface is uneven,YamThree phase dry AC transformer, the tightening bolts are loose, and the installation and processing process is wrong, resulting in oil leakage.When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.

& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.When the output power P of the transformer is equivalent to the input power P, the efficiency & ETA; Equivalent, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer, it is called copper loss.A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.device management,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.Common problems of tap changer of power transformerOn load commissioning:

There are many connection groups of dry-type transformers,YamOil immersed transformer 1600KVA, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.Information recommendation,What is the reason for the shutdown of power transformer?Maintenance contents of power transformerThe 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.Yam,When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.Noise pollution control and prevention measures of dry-type transformerOil leakage at electric welding position
