BOGOInternal structure diagram of oil immersed transformerDo you know what's the proportion of

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.

In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, and the oil sample for simplified experiment shall not be less than 1kg.

BOGO.How to make up oil for oil immersed transformer?

When the manufacturer of the power transformer samples from the automobile oil tank, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb and loosen your thumb to make the oil enter the pipe,

.The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?

There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.

The switching power supply lacks one phase of power;

Oil immersed transformer operation

Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.

When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover,BOGODistribution transformer structure, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb,

project.Noise dispersion of dry-type transformer

The zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; 0” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.

Causes of fire in power transformer

When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate),BOGODistribution transformer model, 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.

Welcome calls .Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

What is the important role of power transformer

BOGO.The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.

The flange surface is uneven, the tightening bolts are loose,BOGOPrice list of 315 KVA box type transformer, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.

The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.
