Description

Prefabricated Distribution Box {ASSEMBLING SWITCH BOX}

The present invention relates to a distribution box for wiring of electrical and communication lines, and more particularly, to a prefabricated distribution box that can be easily assembled and manufactured.

In general, a distribution board refers to a regular arrangement of electrical equipment such as a transformer, a switch device, and other safety devices for operation or control of a power plant or substation, or operation of an electric motor.

These switchboards are mainly installed in group power demands such as schools, buildings, apartment complexes, factories, etc. to receive special high voltages of 6,600V and 22900V supplied from substations, and convert them to commercial voltages of 380V or 220V low voltage to control power supply. Play a role.

In particular, the distribution box serving as a cabinet of the switchboard cuts a plurality of steel sheets to a predetermined size, forms the cut steel sheets by pressing, and the production of the finished steel sheets is performed by painting after welding. .

However, such a distribution box is a method in which a plurality of steel sheets are joined to each other by welding to produce a considerable amount of time due to the characteristics of the welding work, and requires a skilled welding technique, resulting in a decrease in productivity and an increase in manufacturing cost. .

Furthermore, after welding is performed, a process for smoothly processing the welded part is required for painting. As a result, dust is generated due to the machining process, and the finished part has a problem of inferior adhesion to other parts of the steel sheet. .

Therefore, the conventional distribution box has a limitation in improving the quality of the distribution box because there is no difference in quality depending on the welding technician due to the characteristics produced through the welding operation, there is a problem that standardization is difficult, and practically impossible to mass-produce.
