Overview of high-voltage switchgear
Interlocking between the position of the high-voltage switchgear handcart and the circuit breaker
Countermeasures for discharge of high-voltage switchgear
Standardize selection and installation. When installing and processing the chamfer of the busbar and copper busbar, it should be strictly operated in accordance with relevant specifications. By increasing the curvature radius of the electrode to optimize its shape, the electric field is uniformly distributed, thereby increasing the gap breakdown voltage. To avoid excessive concentration of local electric fields, when overlapping the busbar, the exposed part of the fixing bolt should not exceed 3 teeth, and the overlapping part of the busbar should ensure a flat surface. For the selection of shielded contact boxes, select contact boxes with shielding design to achieve uniform distribution of electric field and prevent excessive concentration of electric field. In order to enhance the anti fouling ability, a dual screen casing design is selected.
Types and Common Fault Analysis of High Voltage Switchgear
High voltage switchgear is a very important electrical equipment in the power system. The deterioration of the operating status of the switchgear is one of the reasons for power system failures. So, what are the common faults of high-voltage switchgear?
Quality assurance of switchgear
By investigating and analyzing the processes and operations that affect product quality. Quality records. Investigate and analyze various reports and opinions of Party A (or its representatives), identify potential causes of product quality issues, and propose preventive measures.
