KotokaLatest model of oil immersed transformerHow to solve product shortcomings

() 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, 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.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?Kotoka,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.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.Belfort,Noise pollution control and prevention measures of dry-type transformerThe 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.Due to poor sealing, 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.

Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).When the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil, it is also necessary to carry out high and low temperature test and sludge test, and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor, so it can be managed and used in a mixed manner.The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.safety requirements , the load can be connected.In specific daily life,KotokaThree phase transformer 100kW, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, the greater the output power is. On the contrary, it is very small.The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.

When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.Process inspection,When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage,Kotoka125 KVA dry type transformer, and the whole process of boosting voltage is very complex and there are many principles.Sound in case of phase failureKotoka,The method and whole process of taking oil sample of power transformer are as follows:If the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl, the insulation resistance from the secondary side to the ground should be ^ mh, and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.
