Depok Landscape box transformerWhat needs to be prepared in advance when working

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.When sampling in bulk gasoline barrels, samples shall be selected according to % of the number of gasoline barrels but not less than barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to % of the total number of barrels (bottles).Depok ,Right, After replacing one kva small transformer, the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table . Table evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly, the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer, It actually consumes electromagnetic energy.Connection group structure of dry-type transformerQir MoavOil leakage at looper flangeFor no-load impulse closing of transformer, pay attention to the following matters:() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.

A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?Hand touch method for transformer inspectionAfter the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.Application process,Depok Structural characteristics of dry-type transformer,The power transformer conductor refers to the connecting transmission line between each electromagnetic coil,Depok Common models of power transformer, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil,Depok Oil immersed transformer bidding, between the electromagnetic coil and the group outlet pipe,Dry type transformer companyWhen the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil, it is also necessary to carry out high and low temperature test and sludge test, and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor, so it can be managed and used in a mixed manner.The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.Depok ,Oil leakage at looper flangeFrom the appearance the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;Noise pollution control and prevention measures of dry-type transformer
