1、Digest the drawings:
According to the drawings provided by the user, first check the catalog of drawings, and then assign and classify them. Understand the design intent of the project in accordance with the design instructions and technical requirements of the drawings (if there are bidding documents, the technical requirements of the bidding documents), consider the price required for the calculation of the variable scheme, and pay attention to the floor plan (floor plan The above reflects whether there is a busbar bridge and the length of the busbar bridge between the cabinets).
2、Related Notes:
①、As far as high-voltage cabinets are concerned, in order to meet the five-proof requirements, the incoming cabinet needs to be equipped with a live display (mandatory type: DXN-10, 24/35Q) and an electromagnetic lock, and the outgoing cabinet needs to be equipped with a live display (prompt type: DXN-10/35T ) and grounding switch interlocking device.
②、When the two-way power supply is in, consider the self-switching device, and consider the electrical and mechanical interlocking device (three-in-two) between the two-way power supply and the bus tie.
③、Sulfur hexafluoride ring main unit and KYN28-12 central cabinet generally need to be equipped with temperature and humidity controller and heater.
④、If the interphase and interphase-to-ground distances cannot meet the electrification requirements, busbar vulcanization treatment or special-shaped busbars or heat-shrinkable sleeves for busbar sleeves should be used, and the joints should also be covered with an insulating cover.
