Embodiment 1
[0028] Such as figure 1 , figure 2 , image 3 As shown, the rainproof power distribution box includes a square box body 1 and a plugboard. The static contacts and chutes 2 of several electrical connectors are fixed in the box body 1. The moving contacts of the electrical connectors are installed on the plugboard. , the two sides of the board are coated with guide bars 3, the chute 2 is adapted to the guide bar 3 and fixed on the inner wall of the box body 1, the board includes an upper board 4, a middle board 5, a lower board On the board 6, the upper board 4 is equipped with a single-turn through-the-center transformer and an all-electronic multifunctional electric energy meter, the middle board 5 is equipped with a leakage circuit breaker and a modular surge protector, and the lower board 6 is equipped with a capacitor , miniature circuit breaker, capacitive switching contactor and reactive power compensation controller, in which the guide bar 3 not only makes the upper b...
Embodiment 2
[0034] This embodiment is substantially the same as the first embodiment, except that the material of the floating plate 13 is a PVC hollow plate. The material of the above-mentioned concentrated floating plate 13 is relatively light in weight. When the water level at the bottom of the distribution box rises, the floating plate 13 can be floated, so that the floating plate 13 can block the through holes on the ventilation partition 9 to prevent rainwater from entering the ventilation system. The upper layer of the partition 9.
Embodiment 3
[0036] This embodiment is substantially the same as the first embodiment, except that the material of the floating board 13 is EPS foam board. Foam boards are relatively inexpensive. And the buoyancy it receives under the same state will be relatively large.
