Causes and solutions for the spot on the transformer housing

source：未知 time：2024-12-12 10:28nbsp; click：

The transformer housing is charged mainly because there is a voltage difference between the housing and the ground, which causes a high potential on the housing. This voltage difference may be caused by insulation damage between the housing and the ground, or it may be caused by a fault in the electrical components inside the housing. The following are the specific reasons:

1. Insulation damage between the housing and the ground

When the insulation between the housing and the ground is damaged, a high potential will appear on the housing, causing the housing to be charged. This insulation damage may be due to aging of the insulation material of the housing, or damage to the housing caused by external force.

2. Failure of electrical components in the housing

When the electrical components inside the transformer fail, it may cause a high potential on the housing, causing the housing to be charged. For example, winding short circuits and grounding faults inside the transformer may cause high potential on the housing.

2. Solutions to transformer housing charges

For the problem of transformer housing charges, we can take the following solutions:

1. Check the insulation between the housing and the ground

First, you need to check whether the insulation between the housing and the ground is damaged. If insulation damage is found, it is necessary to repair or replace the insulation material in time to ensure that the insulation between the casing and the ground is intact.

2. Check whether the electrical components inside the transformer are faulty

If the insulation between the casing and the ground is intact, but the casing still has spots, it is necessary to check whether the electrical components inside the transformer are faulty. If the electrical components are found to be faulty, it is necessary to repair or replace the faulty components in time to ensure that the transformer can work normally.

3. Increase the insulation distance between the casing and the ground

Increasing the insulation distance between the casing and the ground can also effectively reduce the occurrence of the casing spot phenomenon. This can be achieved by increasing the thickness of the insulating material or increasing the interval between the casing and the ground.

4. Install protective devices

Installing protective devices on the transformer can also effectively reduce the occurrence of the casing spot phenomenon. For example, overvoltage protection, overcurrent protection and other devices can be installed to protect the electrical components inside the transformer.

The transformer casing spot is a common problem, which may be caused by insulation damage between the casing and the ground, or by electrical component failure inside the transformer. For this problem, we can take the following solutions: check the insulation between the casing and the ground, check whether the electrical components inside the transformer are faulty, increase the insulation distance between the casing and the ground, install protective devices, etc. Through the application of these methods, we can effectively solve the problem of transformer casing with points and ensure the normal operation of the transformer.
