Abstract

The invention discloses a circuit allocation switching unit, comprising a circuit allocation adapter and a low-current unit drawer, wherein the circuit allocation adapter comprises a metal shell; the metal shell is internally provided with an incoming line bus and an outgoing line bus; an outgoing line end of the incoming line bus and an outgoing line end of the outgoing line bus pass through a jack of the drawer on a metal shell panel respectively to form a static bus socket; and the low-current unit drawer is provided with a movable plug which is electrically connected with the static bus socket of the circuit allocation adapter in an insertion mode. Only one movable contact exists between the circuit allocation adapter and the low-current unit drawer when the circuit allocation adapter is connected with the low-current unit drawer in an insertion mode, thus the temperature is low, the inserted connection reliability is high and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a circuit distribution switching unit, in particular to a circuit distribution switching unit with a current of 100A or below in a low-voltage withdrawable complete switchgear MCC cabinet, and belongs to the field of design and manufacture of special devices for low-voltage power distribution cabinets. Background technique [0002] At present, the connection method between the bus bar in the circuit distribution adapter and the cable in the drawer of the small current unit is as follows: Figure 14 As shown: the outlet end of the outgoing copper busbar is plugged with the drawer inlet and outlet insert 29', the outlet end of the copper busbar and the drawer inlet and outlet insert 29' are plugged and then set in the drawer inlet socket, and the drawer inlet and outlet insert is 29' It includes two independent plug-in piece wings 17', one end of the plug-in piece wing 17' is provided with a protrusion, and the other end is provid...
