SheriInternal structure diagram of oil immersed transformerHow was it replaced

The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, 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.

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.

Sheri.Transformer inspection nose sniffing method

Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow,Sheri1600KVA dry type transformer size, wind and sand.

.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?

During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side,SheriHow much is a 200 KVA box transformer, and then make the working voltage impulse closing.

35kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.

Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision 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, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.

Several detection methods for installing transformer

The method and whole process of taking oil sample of power transformer are as follows:

analysis.Naturally, if the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

Oil leakage of cast iron parts

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 from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.

Design brand.Some are tied with plastic tape, and some immediately press the two edges together,SheriPower electronic equipment, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.

It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.

In the case of dry-type transformer operation there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.

Sheri.The switching power supply lacks one phase of power;

The project cost is different. Compared with the purchase price of capacity transformer
