Description

Transfer box and electric distribution facility

Technical Field

The utility model relates to an electrical equipment field particularly, relates to junction box and electric distribution facility.

Background

In the field of large industrial machines, mobile or semi-mobile crushing stations, in particular, are widely used in mineral exploitation. As the mining process progresses, the crushing station needs to move the installation site. During the movement, in addition to the work of transporting and relocating the mechanical equipment, the work of connecting the electrical cables, i.e. disconnecting the cables and reconnecting them, needs to be performed. However, this is very time and labor consuming. For system-level cabling designs, most of the work is spent on the design of the system control logic and architecture, where each subsystem is equipped with an electrical box, which results in a lot of wiring work. For a specific connection job, the connection of the cables is usually made directly using only the terminal block, which is very time-consuming. For the crushing plant there are many functional units (such as power distribution systems, system control of motors, lubrication, heating, lighting, etc. and instruments, communication equipment such as HMIs, PLCs, etc.) in it, all of which require multiple levels of power supply and signal I/O interfaces, so there are a large number of various kinds of control cables in it, which in turn require a large amount of wiring work. In addition, according to the conventional design of cable connections, it would also take a significant amount of effort to recover and verify all connections. All of these efforts result in problems of excessive labor costs, as well as increased downtime of the crushing station, thereby delaying the mining process and ultimately resulting in substantial waste of costs.
