ZhongshanDifference between power transformer and dry-type transformerFeatures of the product

Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.Zhongshan,Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.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.Galway, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Operation and maintenance management of oil immersed transformerThe long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils,ZhongshanStructure introduction of oil immersed transformer, 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.

Noise dispersion of dry-type transformerAccording to statistics, to occupy the main global technical position, the transformer industry depends on two key data, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production manufacturing and application of dry-type transformers all over the world, but it is not a big country.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.How much does it cost?Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, resulting in a lot of steam bodies which dissolve and ignite,ZhongshanDistribution transformer manufacturer, greatly increasing the internal working pressure of the power transformer,ZhongshanTransformer electrical test, causing the ignition of the casing, causing large-scale power failure, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.Oil immersed transformer company(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.

Protective measures for damping of dry-type transformerStatistics,It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, so as to achieve the pressure management of oil leakage.Maintenance contents of power transformerThe power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.Zhongshan,Noise solution of dry-type transformerNoise dispersion of dry-type transformerThe representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring
