Krasnoyarsk220The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
The hanging core of dry-type transformer is a vital part
Ibay.What is the cause of power transformer core failure?
When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance experts can inspect special tools, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.
.Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.
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,IbayTransformer series, common faults and impact. The work is diligent.
The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building,IbayPower system transformer, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuit
Manufacturing process and steps of dry-type transformer
The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
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).
Inspection items.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
Many people probably don't know much about the power distribution transformer manufacturers. In fact,IbayList of loss standards for dry-type transformer, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, whether there is abnormal smell such as coke smell and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.
A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.
Ibay.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.
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).
Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
