The sensor of the high voltage live display device of the standard structure electrical cabinet cannot be installed above the current transformer, because the output cabinet must be equipped with an on switch To the earth. The sensor and ground switch are integrated. installed above the current transformer, the earth switch was unusable, and the distance between the earth blade and the live body did not meet the standard. The transformer was installed too low and the distance between the cable terminal block and the bottom of the cabinet. the plate did not meet the requirements of the standard. The actual installation must conform to the primary system drawings. I have yet to see the system drawings from this design institute that designed the earth knife above the current transformer.
Standard KYN28 cabinet type: outlet cabinets with floor slats do not require insulators, cabinetsPT insulated segmented incoming feeders without floor strips require 3 sensors/unit, overhead incoming cabinets require 3 insulators/Connection row between sections and insulation requires 3 insulators, 3 bushings are required between adjacent cabinets /3 bushings/slot are required to connect bus bridges on adjacent surfaces. Non-standard cabinet types are determined based on actual conditions.
