Kessley80 box type transformerThe detailed process of degreasing work

(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,KessleyPrice of 250kVA box type transformer, 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.

Difference between dry-type transformer and oil immersed transformer:

Kessley.Principle of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage, small current and large characteristic impedance. When there is an AC circuit in the original coil, the communication AC magnetic flux will be caused in the transformer core (or magnetic core), causing the magnetic induction voltage in the primary coil (or current).

For no-load impulse closing of transformer, pay attention to the following matters:

The hanging core of dry-type transformer is a vital part

Sound in case of phase failure

A kind of power engineering equipment that converts the working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering, it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss of electromagnetic energy in the whole process. Therefore the power consumption of the processing plant is all connected with 10kV switching power supply, which is converted into bottom voltage electromagnetic energy through transformer.

If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.

analysis.What is the wavelength of oil immersed transformer?

Power transformer manufacturer

If the power transformer stops running for more than 72h (if the allowable time should be reduced when the ambient humidity is & amp; gt; 95%) it should be insulated before putting into use, and accurately measured with a 2500V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ 300mfl, the insulation resistance from the secondary side to the ground should be ^ 100mh, and the insulation resistance from the iron core to the ground should be & amp; gt; 5mfl (note that the grounding device piece should be removed).

The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.

market.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.

Hand touch method for transformer inspection

The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.

Kessley.If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore,KessleySubstation transformer, which is not suitable for too large or too small.

When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
