Chai eryong, come upS11 dry type transformer manufacturerWhat is the impact of the development of

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

Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

Chai eryong,Chai eryong, come upDry type transformer 10 / 0.4kV, come up.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.

The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.

.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?

In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point,Chai eryong, come upS13-630 power transformer, it will affect the whole power circuit

After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.

The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.

The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, deformation, offset, cracking, loosening ignition smoke, oil leakage,Chai eryong, come upPrice of 800kVA distribution transformer, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity, which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.

Noise dispersion of dry-type transformer

Standard requirements.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.

The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.

Oil immersed transformer

What is the important role of power transformer

High value.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, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, 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.

Maintenance contents of power transformer

Method and process of taking oil sample of power transformer

Chai eryong, come up.(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a guardrail of no less than 7m shall be installed around it, and a warning sign shall be hung at a prominent position.

Brief introduction of zero line of power transformer

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.
