Common sense of reactor Why does the reactor always make a loud noise when it is working?

There are the following reasons:

1. Power harmonics.

Aspect: Reactors.

There is a large surge in the current at the input terminal, or the current changes drastically.

2. Silicon steel sheet.

Aspect: The silicon steel sheet of the reactor should be stacked neatly, and the silicon steel sheet is not tightly stacked, which has caused noise problems;

3. In terms of coils: the gaps caused by the loosening of the wire package have generated noise.

4. Impregnation: incomplete impregnation or too short time will lead to omission of impregnation or insufficient thickness;

5. Fasteners: If the screws on the reactor are loose, they are prone to noise.

6. Power: the reactor capacity is small (unlikely).

To sum up, if the reactor is of reliable quality (the harmonic mutation of the power supply is small, the silicon steel sheet is neatly stacked, the dipping paint is thorough, the thickness is appropriate, etc.), and the output power.

The parameters are consistent with the load, and there should be no noise problems.

Summary. A clicking sound is often heard during operation or just after being charged, which is a normal sound made by the reactor due to thermal expansion and contraction. If there is any other abnormal noise, which may be caused by loosening of fasteners, screws, etc., or internal discharge, it should be reported to the dispatch and checked and dealt with in time.

Hello, I'm sorting out the answer to your question, so please wait a minute

In fact, there are many reasons for the sound of the reactor, the most important reason is that the group letter has a large harmonic component of the system and cutting corners in the design, resulting in the pure magnetic density of the product working plexus, and it is best to check it to see if there is any loose screws.

I hope this can help you, if you are satisfied with me, please give me a thumbs up, I wish you a happy life

How to deal with it? A clicking sound is often heard during operation or just after being charged, which is the normal sound emitted by the reactor due to thermal expansion and cold contraction. If there is any other abnormal noise, it may be the loosening of fasteners, screws, etc., or the aftermath caused by internal discharge, it should be reported and dispatched by the erection rock and checked and dealt with in time.

When the system voltage is allowed, the operation of the dry limb early hollow core reactor installed with outdoor tandem should be avoided during and after the rain, and the operation of the shunt reactor should be generally carried out 2 days after the rain.

The reasons for this can be manifold.

1. Reactor design problems.

2. Switching frequency issues related to BM selection, core material selection, reactor assembly process, fastening method, impregnation method, etc.

High-frequency harmonics will cause the magnetostriction of the core to increase, thus causing noise, which is difficult to avoid, and can be started from the switching frequency, the inductance of the reactor or the matching capacitance.

It is usually solved from the reactor itself.

The device selection is unreasonable, the magnetic saturation is saturated, let the manufacturer deal with the noise reduction!

Reactor. There are two main reasons for the high noise:

1. The harmonics of the power grid are serious.

2. The core insert of the reactor is loose.

Three-phase imbalance.

Not the main reason.

You can find the manufacturer to solve it.

But I'm going to tell you that it's impossible for a reactor to have no sound at all.

There will always be a bit of a buzzing noise, some big and some small! Circle family.

Summary. What should I do if the sound of the 10kV line reactor is abnormal during operation?

Hello, I am helping you inquire about the Xiangzhu Qi Guan Zi Yu Ling Mausoleum, and I will reply to you immediately after finishing it, please wait patiently for a while

What should I do?

Check what kind of problem it belongs to, and there are solutions after each category subdivision on **.

In the above four cases.

OK uh-huh, if it helps you, thank you for giving a thumbs up, and I wish you a happy life
