St. ChristopherLatest standard for dry type transformerFactors of overall market weakness

The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex,St. ChristopherOil type power transformer, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.For kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.St. Christopher,At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.Deterioration damage of transformer core insulationKara-Su,Brief introduction of zero line of power transformerOil leakage of porcelain pot and laminated glass oil level gaugeIn the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV, epoxy resin adhesive shall be used to pour dry-type transformers.For no-load impulse closing of transformer, pay attention to the following matters:wholesaler,High voltage fuse of transformer breaks one phase;Dry type transformer manufacturerNoise pollution control and prevention measures of dry-type transformer

Careless maintenance and insulation damageHonesty is the foundation,The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection,St. ChristopherWhat are the manufacturers of oil immersed transformers, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.When the output power P of the transformer is equivalent to the input power P, the transformer will not cause loss. But in fact 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,St. ChristopherDry type transformer industry ranking, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?St. Christopher and must be technically as a certain pillar. Only in that way,The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV, which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.Seal oil leakageWhat is the wiring mode of dry-type transformer?
