GuaranPower transformer test report,

The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, the good model is the solid model of infinite transformer core column, but there are many calculation methods.Deterioration damage of transformer core insulationGuaran,It 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;, Therefore 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, 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.Barcelona,The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.(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.Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations,GuaranState Grid transformer, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.

The method and whole process of taking oil sample of power transformer are as follows:The step-up dry-type transformer refers to the instantaneous operation of voltage. At this stage, there are few manufacturers of dry-type transformer that can reasonably guarantee the instantaneous step-up in China. The step-up dry-type transformer has strong step-up capacity and good practical effect. The difference depends on that the transformer power switch without excitation regulator does not have the ability to change gear with load. Because this kind of tap power switch can cut off the whole process in a short time during the whole process of gear change, cutting off the load current will cause arc burning between circuit breakers, tap power on and off or short circuit fault, so the dry-type transformer shall be powered off during regulation. Therefore, it is generally used as a dry-type transformer that is not very strict in voltage regulation and does not need to be adjusted frequently.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.Which one is better,The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts with good strength and stiffness, and the distance shall not be less than m; At the angle with actual operation, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Before application, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration,GuaranProduction technology of oil immersed transformer, the bottle cap shall be tightly closed and cannot be opened before application.

The 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).High quality and low price,Different diversion methods, dry-type transformers mostly use silica gel waterproof casing while oil transformers mostly use porcelain waterproof casing;After the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.Guaran,Oil leakage at looper flangeOil leakage of bolt or pipe external threadBrief introduction of zero line of power transformer
