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.

Abstract

The invention provides a rain-proof distribution box, and belongs to the technical field of power distribution equipment. The rain-proof distribution box comprises a square box body and a plugboard, wherein static contacts and slide chutes of a plurality of electric connectors are fixed in the box body; movable contacts of the electric connectors are arranged on the plugboard; guide sliding strips coats two sides of the plugboard; the slide chutes are matched with the guide sliding strips and are fixed on the inner side wall of the box body; the plugboard comprises an upper plugboard, a middle plugboard and a lower plugboard; two portable handles are fixed on the upper end surface of each plugboard; a hand push handle is arranged at the outer end of each plugboard; a ventilating partition plate is also horizontally arranged in the box body and is located below the lower plugboard; a plurality of air holes are formed in the middle of the ventilating partition plate; a lifting rod is vertically arranged at the center of the ventilating partition plate in a penetrating manner; the upper end of the lifting rod is connected with a support block; the lower end of the lifting rod is connected with a floating plate; and the lifting rod ascends and then the air holes are completely plugged by the floating plate. According to the rain-proof distribution box, the distribution box and the outside are kept in good ventilation; and the rain-proof distribution box has good waterproofness and high safety.

Description

technical field [0001] The invention belongs to the technical field of power distribution equipment and relates to a rainproof power distribution box. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. The distribution box is one of the most basic power supply facilities in urban construction. At present, the distribution box is mainly composed of a box body and internal components. However, the current distribution box is prone to overheating and short-circuit accidents after long-term use, and the current distribution box...
