What's the difference between electric control cabinet, electric control cabinet, power distribution cabinet and distribution box?

Strictly speaking, there is still a difference.

From the appearance and structure, the electric control cabinet and the distribution cabinet (switchboard) belong to the same category, and the electric control cabinet and the distribution box belong to the same category.

The electric control box and distribution box are sealed on six sides and are generally installed on the wall. There are knock holes at the top and bottom of the box, which is convenient for wires and cables to enter and exit the electric control box and distribution box.

The electric control cabinet and power distribution cabinet are sealed on five sides and have no bottom. It is usually installed on the floor against the wall.

Usually, the switchboard is sealed on two sides, but it is also sealed on three, four and five sides. The switchboards are all installed on the floor, but the back of the switchboard cannot be against the wall. There must be room for operation and maintenance behind the switchboard.

How many sides of the switchboard are sealed? You need to ask for it when ordering. For example, five switchboards are installed side by side, only the first one needs a baffle on the left side, the fifth one needs a baffle on the right side, and the second, third and fourth ones are left and right open. If a switchboard is installed and used separately, there should be baffles on both sides.

In most cases, the back of the switchboard is open, and there can be a door on the back according to the needs of users, which can be dustproof and convenient for operation and maintenance.

From the functional point of view, the distribution board, distribution cabinet and distribution box belong to the same category, and the electric control cabinet and electric control cabinet belong to the same category.

Generally speaking, the switchboard distributes electric energy to lower-level distribution cabinets and distribution boxes, or directly to electrical equipment. Power distribution cabinets and distribution boxes directly distribute power to electrical equipment, and sometimes power distribution cabinets distribute power to lower-level distribution boxes.

The electric control cabinet and the electric control cabinet are mainly used to control the electric equipment, and also have the function of distributing electric energy to the electric equipment.

Power distribution cabinets, distribution boxes and distribution boards are mainly equipped with knife switches, knife switches, air switches, fuses, magnetic starters (contactors), thermal relays, and sometimes current transformers, voltage transformers, ammeters, voltmeters and watt-hour meters. In addition to the above electrical components, the electric control cabinet and cabinet are also equipped with intermediate relays, time relays, control buttons, indicator lights, changeover switches and other functional switches and controls. Some even installed frequency converter, PLC, single chip microcomputer, I/O converter and AC /DC voltage regulator. In the electric cabinet, some will also install temperature, pressure and flow display instruments on the electric cabinet.
