External electric cabinet suitable for module unit

Abstract

The embodiment of the invention provides an external electric cabinet suitable for a module unit. The external electric cabinet comprises an external engineering junction box and a dual-system main-control box. The external engineering junction box comprises an input power terminal assembly XT and an output power terminal assembly XT6. The input power terminal assembly XT is used for connecting with external engineering power lines. The output power terminal assembly XT6 is used for connecting with the dual-system main-control box and external loads. The dual-system main-control box comprises an input control terminal assembly XT5 and a control terminal assembly CN. The input control terminal assembly XT5 is used for receiving a control signal sent by an external control circuit. The control terminal assembly CN is used for controlling an input power supply of the module unit. The external electric cabinet is utilized so as to be suitable for connection of engineering wires in multiple kinds. There is no need to connect each load. Therefore, the external electric cabinet suitable for the module unit has the following beneficial effects: production and wiring as well as after-sales, installation and wiring are convenient; and with the external electric cabinet, university of the wiring design can be improved.

Description

technical field [0001] The invention relates to the field of electric control boxes, in particular to an external electric control box suitable for a modular unit. Background technique [0002] When the air conditioning unit is installed, it is not only necessary to connect the air conditioning unit to the external engineering line, but also to separately design and connect the external engineering line for each external load, so that the air conditioning unit can operate normally. In order to make the unit operate normally and safely, it is necessary to add various electrical safety equipment and control equipment, which will form a large number of wiring during production and installation, and increase the burden during production and installation. Moreover, due to the large number of wirings, miswiring is easy to occur in the actual installation process, which makes the air conditioning unit or external load prone to failure.
