联合厂房是大面积的多功能的综合体,一般设有不止一台变压器。与只需单台变压器的独立车间等建筑物相比,它的低压电气母线开关的安排较复杂一些。这里简要介绍我们的一般做法。一、分路开关在各分支母线与主干母线的连接处,我们一般都装设分路开关。这些分路开关,一般都采用自动开关。它主要起对分支母线短路、过载的保护作用,并附带起对检修拉闸或事故跳闸后限制停电面的隔离作用。
The joint factory building is a large-area multi-functional complex and generally has more than one transformer. Compared to buildings such as independent workshops that require only a single transformer, its low-voltage electrical bus switch arrangement is more complex. Here is a brief introduction to our general practice. First, the shunt switch At the connection of each branch bus and the trunk bus, we usually install the shunt switch. These shunt switches generally use automatic switches. It mainly acts as a protection against the short-circuit and overload of the branch bus, and it also acts as a barrier to restrict the blackout surface after maintenance or accidental tripping.
