Difference between aviation plug and power plug

The structure of the power plug is similar to that of the round aviation plug. The only difference is that the round aviation plug is more suitable for industrial electricity use because it can bear a higher voltage. Some of them are converted from high voltage electricity, which can only be met by the round aviation plug. The general power plug cannot meet the voltage requirements.

1. Types of round aviation plugs: single-phase plug and three-phase plug.

2. Single-phase round aviation plugs are divided into: single-phase two-pole plugs, single-phase grounding plugs (single-phase three-pole plugs).

3. Three-phase round aviation plug power plug: three-phase four-level plug.

4. The structure of the plug: copper sheet (moving contact), wiring terminal, plastic shell, screws, etc.

5. Plug symbol: XP single-phase single-pole plug symbol.

6. How to identify the contacts of a single-phase plug: The method for identifying the contacts of a plug is exactly the opposite of that of a socket.

That is, "left live and right neutral". The left contact is connected to the live wire, the right contact is connected to the neutral wire N, and the middle contact is connected to the ground wire.

7. Rated voltage of the plug: The rated voltage of the single-phase plug is 220V. The rated voltage of the three-phase plug is 380V.

Structural characteristics of circular aviation plug:

- According to the installation method: mobile, surface-mounted, concealed;

- According to whether the socket has a protective device: without protective device, with fuse, with miniature circuit breaker;

- According to whether the socket has an interlocking device: without interlocking, with mechanical interlocking, with electrical interlocking;

- According to whether the socket is equipped with a stable transformer: without transformer, with transformer;
