Fukushima How much is a box transformerStatus of motion fault diagnosis

The zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit but only as a maintenance line. Use the affirmation of the earth & ldquo; 0” Voltage. When the machine and equipment casing is electrified,Fukushima Rated current of 400 KVA dry-type transformer, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.

Solenoid insulation deterioration

After tightening the loose bolts, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.

.Noise dispersion of dry-type transformer

The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?

Fault judgment of power transformer

For no-load impulse closing of transformer, pay attention to the following matters:

Transformer manufacturers generally adopt IP20 protective casing, which can avoid the entry of solid dirt with a diameter of more than 12mm, rats, snakes, cats, birds and other animals,Fukushima Construction procedure of oil immersed transformer, and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, IP23 protective casing can be adopted, which can avoid being equally divided with the above IP20 protective effects However, IP23 casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.

Dry type transformer factory

Sales Department.The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).

The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.

Power transformers are used in all walks of life

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?

Create brilliance.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.

Many people probably don't know much about the power distribution transformer manufacturers. In fact, 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,Fukushima Standard for transformation ratio of power transformer, 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.

Seal oil leakage

Fukushima .Causes of fire in power transformer

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).

When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.
