Causes of fire in power transformer

If the volume of power transformer is too small, which is not suitable for too large or too small.

Helsingborg.There is a magnetic induction line crossing in the transformer core the rated capacity of the transformer should be selected according to the power consumption, which will cause induced electromotive force on the plan with the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.

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.

.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, 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.

What is the reason for the shutdown of power transformer?

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.

The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;

Noise dispersion of dry-type transformer

Product line.(5) 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, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.

According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.

Fair price.Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings,Helsingborg30 KVA three-phase transformer,HelsingborgPower recovery transformer, commerce, airports tunnel construction, chemical enterprises and factories.

Helsingborg.Operation and maintenance management of oil immersed transformer

The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection,Helsingborg1200kva power transformer, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.

Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.
