Busbar copper row switchgear - chest tray estimation method for drawer
1. A circuit breaker inlet cabinet is the same as GGD. Single row up and down 15 meters double row = 15*2=30 meters
Single row down and out 8 meters double row = 8*2=16 meters
2, fixed separation: Large circuit breaker combination: the first 5 meters; the second is 7 meters, the third is 9 meters (Note: large circuit breakers are 800H or more)
Molded case circuit breakers up to 800H: The copper bar gauge of all breaker current sums is *2 meters; the circuit breakers of 400H to 800H are reported for 3 meters each.
3, drawer type: GCK, GCS: 400H and above need to report copper row 3 meters; several circuit breaker current sum of copper row specifications * 2 meters. MNS: The circuit breakers of 630H and above are counted as 1 meter each; the sum of the copper bars of several circuit breakers is *2 meters.
4. The communication cabinet and capacitor cabinet are connected to the GGD, and the capacitor cabinet-like algorithm.
Capacitor cabinet: If it is 800MM cabinet width, it is generally calculated as 8 meters. If the cabinet width is increased, it will be increased appropriately (the knife switch is estimated to be 2 meters from the top to the horizontal and 1.5 meters from the bottom to the horizontal)
Contact cabinet: - only the circuit breaker contact cabinet and a circuit breaker incoming line cabinet are up and down 15 meters, two circuit breakers contact cabinet = - only circuit breaker contact cabinet * 2 = 15 * 2 = 30 meters
5, fixed split type is plug-in type, board rear wiring, air switch is molded case circuit breaker, economical camera cabinet is horizontally placed on the top of the cabinet, standard horizontal row is located behind the cabinet.
6, the price of the chest of the chest of drawers = the price of the channel and vertical row (vertical row is equal to the total current of several circuit breakers corresponding to the copper bar specifications) + the price of the chest of drawers (fixed cabinet +100 yuan)
The specifications of the three copper bars that are supplied by the shell manufacturer behind the drawer cabinet are determined according to the sum of the currents of several circuit breakers.
7. The vertical row in the channel of the low-pressure drawer cabinet is generally 40*6, 50*6, 60*6, 80*6, 100*6, 120*6.
