Anti Eddy Current Treatment Of Prefabricated Cabin Type Substation Wall

Anti eddy current treatment of prefabricated cabin type substation wall

First of all, let me explain to you what eddy current phenomenon is. It is a physical phenomenon discovered by French physicist Leon Foucault, which is caused by the intersection of a moving magnetic field and a metal conductor. Simply put, it is caused by the electromagnetic induction effect, which generates current circulating inside the conductor.

The reason why we perform anti eddy current treatment on prefabricated modular substations is to effectively reduce eddy current intensity and thus reduce energy loss. Due to this induced current, which is like a vortex in water, this phenomenon is called eddy current

Prefabricated cabin manufacturers usually adopt anti eddy current measures such as:

When multiple devices are connected in parallel branches to a common busbar passing through a prefabricated box, the busbar duct for fixing the busbar should use metal plates, such as non magnetic materials such as steel plates or aluminum plates, as protective shells. Used to cut off the magnetic circuit.

2. The door panels and frames with metal clips installed on the prefabricated cabin box should also be made of non magnetic materials such as stainless steel or aluminum to ensure that the magnetic circuit around the busbar does not form a loop. This reduces energy loss and heat generation.

Based on the above introduction, it is still necessary to carry out anti eddy current treatment for prefabricated modular substations. Due to the presence of high current copper bars in the cabinets of high-power electronic and electrical equipment, eddy currents can cause the cabinets to heat up, not only causing additional power loss to the electronic and electrical equipment, but also affecting the overall temperature of the electronic and electrical equipment. This can exacerbate the temperature rise of the cabinets and cause local temperatures to be too high, which can have a very negative impact on the equipment
