Report thus shut down, it is heavy then cause control error, so as to damage electrical equipment, cause great device damage.It is in addition, existing automatically controlled
Cabinet internal space design is not reasonable, causes many electrical equipments to be so close together at work, and during electrical equipment work
Caused magnetic field, which will also result in, to be interfered.
Utility model content
（One）The technical problem of solution
For the disadvantages mentioned above present in prior art, the utility model provides what a kind of anti-electromagnetism of layering interfered
Electrical control cubicles, the electrical equipment inside the electrical control cubicles present in prior art can be effectively overcome to produce mutual electromagnetic at work
The defects of interference.
（Two）Technical scheme
To realize object above, the utility model is achieved by the following technical programs：
A kind of electrical control cubicles for being layered anti-electromagnetism and interfering, including hollow cabinet, the hollow cabinet is interior to be provided with metal screen
Layer is covered, the hollow cabinet inwall is provided with reactor and grounding copper bar, first partition is provided with inside the hollow cabinet,
Bearing block is fixed with the first partition, second partition, the first partition and second partition are fixed with the bearing block
Inside it is equipped with metal screen layer.
Preferably, the reactor is oppositely arranged with grounding copper bar.
Preferably, the first partition is provided with two.
Preferably, the second partition is oppositely arranged with first partition.
Preferably, each first partition is provided with three bearing blocks.
（Three）Beneficial effect
Compared with prior art, it is provided by the utility model a kind of to be layered electrical control cubicles that anti-electromagnetism interferes and utilize the
One dividing plate and second partition will be separated into each separate space inside electrical control cubicles, and are all provided with first partition and second partition
There is metal screen layer, so as to form double layer screen layer, coordinate filtering demagnetization and ground connection demagnetization, can effectively block positioned at each only
The mutual electromagnetic interference of electrical equipment in vertical space so that the electrical equipment in electrical control cubicles can normal work；It is meanwhile empty
Metal screen layer in heart cabinet can also block the electrical equipment inside electrical control cubicles to electromagnetism caused by extraneous electrical equipment
Influence.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
