What are the requirements for the switchgear distribution device setting
Guiyang switchgear that under normal circumstances, connecting device of switch cabinet body and the external cable is completed in cable compartment, this cable can up and down and out; and when the zero sequence current transformer in the cable compartment, can be more convenient for the installation and maintenance。
In the switch cabinet, if it is the same power distribution system, you can limit the short-circuit current through the current limiting reactor, bus voltage stability in a certain value; also could reduce the components of short circuit strength requirements, making the switch cabinet stability condition。
As a power distribution device for switch cabinet, two plug-in the drawer unit should have an adequate number, so as to satisfy the computer interface and control circuit of the contact number of the ball; and as far as possible to improve the heat capacity of the adapter, helps to reduce greatly due to the temperature rise to the attached adapter connector, temperature cable head, bring up the partition.
In the internal switch cabinet power distribution device, function unit, isolation between compartments between must be clear and reliable, not because of the failure of one unit and affect the work of other units, the fault limits in the minimum range; require the use of flat type busbar arrangement, the device of the dynamic and thermal stability, can withstand short circuit current impact. Guiyang switch cabinet small editor to share here.
