MeknesWhat are the oil immersed transformer protectionsThe principle of storage and transportation

After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?

Meknes.For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than 5%,MeknesDistribution transformer model, there is generally no problem. However, if there is more new remaining oil, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.

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 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.

Solenoid insulation deterioration

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.

Seal oil leakage

With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.

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.

property right.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.

Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.

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.

Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.

target.When the full load test is carried out and everything is normal, the load can be connected.

How to make up oil for oil immersed transformer?

Due to poor sealing,MeknesDistribution transformer wiring group,MeknesWind power box transformer, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.

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

Analysis of common faults of oil immersed transformer:

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.
