Description

Monitoring unit and cubical switchboard of bimodulus drawer

Technical Field

The application relates to the technical field of power distribution cabinets, in particular to a monitoring unit of a dual-mode drawer and a switch cabinet.

Background

A plurality of drawers are integrated in the low-voltage power distribution cabinet, and each drawer is internally provided with a monitoring unit for controlling the electricity consumption of a user; the monitoring unit generally comprises a circuit breaker, a current detector and a current protector, both of which are electromagnetic induction coils for detecting the current entering the circuit breaker; the incoming line end and the outgoing line end of the circuit breaker are connected to structures of different shapes, so if the current protector and the current detector of the circuit breaker are respectively arranged at the incoming line end and the outgoing line end of the circuit breaker, the structures of the incoming line end and the outgoing line end need to be adaptively adjusted, and therefore production cost is increased. And from the perspective of being convenient for assemble, the current protector and the current detector are integrated at the inlet wire end or the outlet wire end of the circuit breaker so as to achieve the purpose of being convenient for assemble.

The scheme is that only one set of detection units are integrated in the drawer, and the drawer belongs to a single-mode drawer. When two sets of detection units are integrated in the drawer, the double-mode drawer belongs to the double-mode drawer. When two sets of monitoring units are integrated in the drawer, two sets of monitoring units are required to be arranged in the drawer where one set of control equipment is originally arranged, so that the layout requirements on electrical components in the drawer are further improved. In the existing arrangement mode of the current detector and the current sensor, the current detector and the current sensor are arranged at the wire inlet end of the circuit breaker or the wire outlet end of the circuit breaker, so that one end of the circuit breaker is large in size and long in length, a large installation space is required to be reserved for the circuit breaker, and then the installation of other electrical components is extruded, so that the space between the other electrical components is too tight, and the overall layout in the drawer is affected.

In summary, there is a lack of a dual-mode drawer monitoring unit and a switch cabinet that can avoid the influence on the layout of the remaining electrical components in the drawer due to the too large size of the circuit breaker.

Further, a positioning hole is formed in the base. Penetrate the locating pin in the locating hole, can fix the base on the circuit breaker, increase the compactness that circuit breaker and terminal are connected.

Further, the binding post comprises a base body and a conductive piece, wherein a first connector is arranged on one side of the base body, a second connector is arranged on the other side of the base body, and the first connector and the second connector are detachably connected.

In this scheme, dispose first joint and the second joint that can dismantle the connection respectively in the both sides on the pedestal, and then when needs dispose the connecting seat on the circuit breaker, can let earlier connect together through first joint and second joint between the pedestal of three wire holder, and then realize needing to dispose three wire holder in inlet wire end or the play line end of circuit breaker and link together, then only need fix a position to a connecting seat and just can realize other wire holders synchronous positioning, the other connecting seats of configuration at this end no longer need fix a position alone promptly, so assembly efficiency can be higher.

Further, the current detector and the current protector are milliamp-level current induction coils. The current detector and the current protector are arranged to be milliamp-level current induction coils, so that the volumes of the current detector and the current protector can be effectively reduced, the volume of the circuit breaker is reduced, and the volume of the drawer can be made smaller.

As a second aspect of the present application, in order to solve the technical problem that the size of the circuit breaker is too large, some embodiments of the present application provide a switch cabinet, including the monitoring unit of the dual-mode drawer.

To sum up: the beneficial effects of the application lie in that, provide one kind and can avoid too big at the volume of circuit breaker, influence the monitoring unit and the cubical switchboard of the bimodulus drawer of other electrical assembly overall arrangement in the drawer.
