An intelligent motor control cabinet

Abstract

The invention relates to an intelligent motor control cabinet, which is composed of a top level room, a grounding aisle, a drawer unit, a wire and cable room, and a cabinet body. The top level room is equipped with a network control fixing plate, and the network control fixing plate is equipped with a network connection module; There is a grounding bar installed in the grounding aisle; each motor control circuit is installed in the drawer unit; the rear of the drawer unit is respectively equipped with a network plug-in, a control plug-in, a grounding plug-in, a wire plug-in and a load plug-in; the rear of the cabinet corresponds to the drawer unit The position device has the corresponding network plug-in, control plug-in, and grounding bar; the load plug-in is installed on one side of the partition board, and the user load terminal is installed on the other side of the partition board; the wire and cable indoor device has a zero row; the rear of the cabinet is installed There are horizontal busbar copper bars; the top of the cabinet is equipped with hoisting angle steel. The invention is an intelligent motor control cabinet which is safe in use, convenient in installation, compact in structure, good in shock resistance and impact resistance, highly flexible in assembly, and convenient in disassembly.

Description

Technical field: [0001] The invention relates to a control cabinet, in particular to an intelligent motor control cabinet. Background technique: [0002] At present, in the power control of factories, mining enterprises and institutions (focus on motor operation control), most of our country adopts traditional relay contact control methods and discrete logic controller control methods with some intelligent control functions. All connections of the relay contact control method must be realized by hard wiring. This method is restricted by design ideas, cabinet structure and other reasons. It is very troublesome to change the control logic. Moreover, the main bus is set on the top of the cabinet. It is not easy to install and maintain; although similar control methods such as Programmable Logic Controller (PLC) have some intelligent control functions, the equipment status and other signals are still transmitted to the control module and other components in a one-to-one hard-wired ma...

AI Technical Summary

Problems solved by technology

All connections of the relay contact control method must be realized through hard wiring. This method is limited by design ideas, cabinet structure and other reasons. It is very troublesome to change the control logic. Moreover, the main busbar is set above the cabinet. It is not convenient for installation and maintenance; although the logic controller (Programmable Logic Controller, referred to as PLC) and other similar control methods have some intelligent control functions, the signals such as equipment status are still transmitted to the control module and other components in a one-to-one hard-wired way, and the control The module has a fairly strong intelligent control function, and the transmission from the control module to the control layer and the management layer adopts intelligent communication transmission, but the design idea of ​​this method is to treat the logic controller as an independent whole rather than as many organically connected One unit of the control method is considered, so the cabinet structure of this method is single, and the reliability, expansion and flexibility of the main line-branch line or daisy chain connection structure are not enough, whether it is to add a new unit or from the upstream chain. If the link is disconnected, it will affect the operation of the downstream networking equipment, and even cause the shutdown of the equipment, and the equipment layer signal such as the equipment status is still transmitted to the control module and other components in a one-to-one hard-wired way. complex, difficult to change
