The quality problems in the installation of complete sets of power distribution cabinets are often ignored by many workers, and the improper handling of these problems has brought a lot of trouble to the actual work. So what should we pay attention to in actual operation?
First of all, let’s analyze some common quality problems, mainly as follows:
The welding slag at the welding place of foundation steel is not cleaned cleanly, the rust is not cleaned cleanly, the paint brush is uneven, and there is brush leakage.
Paint of electrical components and porcelain parts in the cabinet (panel) is damaged.
The control line in the cabinet (panel) is not tightly pressed, and the wiring is wrong.
The auxiliary switch of the secondary wire loop of handcart cabinet failed to switch, and its mechanical performance was poor.
According to the above problems, we should take corresponding measures:
Improve the quality awareness, strengthen the operator’s sense of responsibility, and do a good job in process overlapping and self-inspection and mutual inspection.
Strengthen the sense of responsibility and take specific protective measures.
Strengthen technical study and improve technical quality. Strengthen study and improve work responsibility.
After repeated trial and adjustment, the parts that fail to meet the requirements require replacement by the factory.
