Detailed Description

Referring to the drawings, as shown in the figures, a wire inlet chamber 1, a main receiving chamber 2, a metering chamber 3, a reactive compensation chamber 4 and a feed-out chamber 5 are respectively formed in a distribution box body through partition plates, a temperature sensor 8 of the main receiving chamber is installed in the main receiving chamber 2, a temperature sensor 7 of the feed-out chamber is installed in the feed-out chamber 5, and a temperature controller 6 is installed on an installation beam of a feed-out switch in the feed-out chamber 5. A main receiving chamber fan 9 is arranged at the bottom of the main receiving chamber 2, and a feeding-out chamber fan 10 is arranged at the bottom of the feeding-out chamber 5; the

terminals

5 and 6 of the temperature controller are control power supplies which are led out of the busbar in the cabinet. The

terminals

1, 2, 7 and 8 of the temperature controller are respectively connected with the blue line and the gray line of the temperature sensors 7 and 8 in the main receiving chamber 2 and the feeding-out chamber 5, and the

terminals

3 and 4 of the temperature controller are respectively connected with the terminals L, N of the fan 9 at the bottom in the main receiving chamber 2.
