The whole process of hanging the core of dry-type transformer is more critical, and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore,ZabinkaConstruction power transformer, the hanging core of dry-type transformer should be carried out according to the above matters, so as to promote the safety of dry-type transformer!The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.Zabinka,At that time, only a few companies in China could produce kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.Due to poor sealing generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.Dzhalagash,Dry type transformer companyNoise pollution control and prevention measures of dry-type transformerThe 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, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.

Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.The dry-type transformer is composed of two winding resistances, resulting in four wiring groups: & ldquo; y, & ldquo; D, & ldquo; y, D & rdquo; and & ldquo; D D & rdquo;. In China, only & ldquo; y, Y & rdquo; and & ldquo; y, D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line, it will not be upgraded. All marks show that with neutral line, it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn wiring group, when UAB and UAB overlap, the minute hand points to . & ldquo; & rdquo; in the new wiring group, it is indicated by & ldquo; & rdquo.Affordable price,If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, which is not suitable for too large or too small.Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.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, 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.

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.Quality improvement,Noise pollution control and prevention measures of dry-type transformerIt can be seen from the above that from the perspective of power saving, in some cases, transformers & ldquo; A small horse pulls a small car & rdquo; Can't compare with & ldquo; Middle car & rdquo;, Even less than & ldquo; Great Lars little dragons & rdquo;,ZabinkaOutdoor dry-type transformer structure, the loss of transformer full load and load must be considered in the calculation, and the results can be properly made in terms of power saving or power consumption. According to the correlation between the load rate and the transformer capacity: . The transformer load rate and power saving will be brought into the formula: the load index of the transformer, that is, the operating load and rated capacity of the transformer . Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P, and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer: that is, the formula is reduced The load index is the load index when the transformer operation loss is small and the rate is large and the rate is large when the specific copper loss is equivalent to iron loss.& 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.Zabinka,Zabinka2000 KVA dry type transformer,Dry type transformer companyIn the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.
