Abstract
The utility model discloses an intelligent all-insulation totally-enclosed plenum type ring main unit, which mainly comprises a main loop and an intelligent control loop. An inlet cable head (1) is connected with the static contact of an earth switch (2) and the movable contact of the earth switch (2) is connected with the static contact of a vacuum circuit breaker (4). The movable contact of the vacuum circuit breaker (4) is connected with the static contact of an isolating switch (5). The movable contact of the isolating switch (5) is connected with the incoming line seat of a fuse (6). The leading-out terminal of the fuse (6) is connected with an outlet cable head (7). Then the outlet cable head (7) is connected with a main bus (9) to form the main loop. All the elements of the main loop are fixedly arranged in a plenum box (10) filled with gas SF6. A voltage transformer (3) is connected in parallel with the main loop. A current transformer (8) is sleeved on the main bus (9). The secondary lines of both the voltage transformer (3) and the current transformer (8) are respectively connected with the data input terminal of a microcomputer comprehensive protector (11). The control output terminal of the microcomputer comprehensive protector (11) is connected with the electric control terminal of the vacuum circuit breaker (4). In this way, the intelligent control loop is formed.
