SanfiaStandardCommon problems of tap changer of power transformer
The main reason is that the welding quality of electric welding is poor,GarissaHow much is a 500 KVA box transformer, there are empty welding, open welding, and the potential safety hazards are exposed after operation. In addition sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device,Garissa1200kva power transformer,GarissaReactance transformer, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.
Oil immersed transformer operation
.Noise pollution control and prevention measures of dry-type transformer
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.
What is the important role of power transformer
When the full load test is carried out and everything is normal, the load can be connected.
Transformer inspection ear
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, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.
Honest service.In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
Dry type transformer
When the full load test is carried out and everything is normal, the load can be connected.
In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.
quality index.The switching power supply lacks one phase of power;
Protection mode for type selection of dry-type test transformer
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.
Garissa.Power transformer manufacturer
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
