VardaninStructure introduction of oil immersed transformerShipments increased at the closing of the two sessions

The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.

The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).

How much is the power transformer

.It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.

The insulating layer in the middle of the silicon steel plate is aging,VardaninWhat qualifications are required to install power transformers, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, 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, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.

When oil samples are used,VardaninTemperature standard for oil immersed transformers, the safety and fire safety technical specifications on the spot shall be strictly implemented.

Difference between dry-type transformer and oil immersed transformer:

Power transformer is indispensable for power stations and substations, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.

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

Dry type transformer manufacturer

In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a warning sign shall be hung at a prominent position.

How is the quality level of dry-type transformer compared with foreign countries?

Operation of oil immersed transformer

Vardanin.When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate) and a guardrail of no less than 7m shall be installed around it, 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.

Manufacturing process and steps of dry-type transformer

The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
