ChangyangTransformer power three-phaseQuality Assurance

The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.

When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover,ChangyangTechnical parameters of power transformer, use the cleaned and dried rubber stopper to the oil. At the same time clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,

Changyang.Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region,ChangyangTemperature measurement of dry-type transformer, and then the oil mixing test should be carried out.

In terms of the place of use, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;

.Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.

In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

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,ChangyangSingle phase oil immersed transformer, so as to ensure the reliable and stable operation of machinery and equipment.

What is the important role of power transformer

The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by 100kW motor, so the usual load is 200 KW, CST = 0. One 750kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only 34%

(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.

Installation material list.In specific daily life 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, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is 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.

From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;

On the contrary, it is very small.

When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment but also make the transformer operate at full load or load for a long time, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.

plan.Noise solution of dry-type transformer

The efficiency of transformer is closely related to the output power level of transformer. Generally, the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power, the lower the efficiency.

What about oil immersed transformer fire?

Changyang.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.

For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, power failure, damage to machinery and equipment, etc.
