SuyaniPicture of oil immersed transformer disassemblyDoes it have any effect on practicality?

In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, what is the wiring mode of dry-type transformer?

Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.

Suyani.Transformer inspection nose sniffing method

Due to poor sealing, generally, it will lead to common faults of oil leakage.

.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.

Method and process of taking oil sample of power transformer

The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.

At that time, only a few companies in China could produce 500kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.

Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition,SuyaniIntroduction to dry type transformer,SuyaniTransformer box, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.

quality.Dry type transformer

When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.

During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.

Protective measures for damping of dry-type transformer

production costs.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value,SuyaniPower transformer, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.

Once the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.

There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.

Suyani.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, the rated capacity of the transformer should be selected according to the power consumption which is not suitable for too large or too small.

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.

Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.
