What is the electrical clearance in the small power distribution unit?

In power systems, electrical clearance refers to the distance between two conductors insulated from each other in electrical equipment. In the small power distribution unit, the electrical clearance usually refers to the distance between the breaking contacts in electrical equipment such as disconnectors and circuit breakers. The size of the electrical gap usually determines the insulation strength and performance of the equipment.

Under normal circumstances, the distance of the electrical clearance needs to meet the requirements of relevant standards and specifications to ensure the safety and reliability of the equipment. If the electrical gap is too small, it will easily lead to excessive arc discharge during breaking, which will damage the equipment and cause safety accidents such as fire; if the electrical gap is too large, it will easily lead to burning loss and discharge energy loss during breaking, reducing equipment service life and efficiency.

Therefore, in the design and maintenance of the small power distribution unit, it is necessary to reasonably select and control the size of the electrical gap to ensure the normal operation and safety of the equipment. At the same time, it is necessary to carry out regular inspection and maintenance on the small power distribution unit to ensure the effective insulation and connection of the electrical gap.
