Abstract
The utility model discloses a waterproof ventilation outdoor multifunctional low voltage comprehensive distribution box. The waterproof ventilation outdoor multifunctional low voltage comprehensive distribution box is characterized in that the waterproof ventilation outdoor multifunctional low voltage comprehensive distribution box comprises a box body; a box door is arranged on the front side of the box body; a small ridge propeller strut box cover is arranged at the top of the box body; verge plates are arranged on both sides of the box cover; groove type ventilation holes are arranged between both sides of the box body and the verge plates; a wire inlet and a wire outlet are arranged at the lower part of the box body; a knife switch and a circuit breaker are arranged in the box body; and a power supply inlet wire is connected with the knife switch and the circuit breaker in sequence. According to the utility model, small ridge bidirectional ventilation is adopted on the top cover of the distribution box; ventilation is carried out on both sides; the verge plates prevent rain from coming into the distribution box; the safety of an electrical control device can be effectively protected; and by improving the circuit breaker and based on the functions of electric leakage and short circuit protection, overvoltage, undervoltage, zero curve breaking protection are increased, thus power supply reliability and stability are increased.
Description
Technical field
The utility model relates to the outdoor Multifunctional low-tension integrated distribution box of a kind of water-proof ventilation.
Background technology
Existing distribution box top is flat cover; impeded drainage has the water storage phenomenon, the venetian blind type louvre; can not stop entering of various wind direction rainwater; the distribution box inner air flow is not smooth, causes the control panel heat in time not discharge, and burns easily control panel; and the protective switchgear in the low-tension distribution box; only possess electric leakage, two kinds of functions of short-circuit protection, " disconnected zero failure " in actual motion, occur, or overvoltage occurs, can not play a protective role when under-voltage.
Summary of the invention
For solving above-mentioned existing shortcoming; main purpose of the present utility model is to provide a kind of outdoor Multifunctional low-tension integrated distribution box of water-proof ventilation of practicality; the distribution box top cover adopts little backing bi-directional discharging; both sides ventilate, and the fascia rainwater-proof enters, and can effectively protect the safety of control panel; and by improving circuit breaker; on the basis of electric leakage, short-circuit protection function, increase overvoltage, under-voltage, disconnected zero protection, increased power supply reliability and stability.
For reaching above-described purpose, the outdoor Multifunctional low-tension integrated distribution box of water-proof ventilation of the present utility model is taked following technical scheme:
The outdoor Multifunctional low-tension integrated distribution box of a kind of water-proof ventilation, it is characterized in that, it comprises casing, described casing front side arranges chamber door, and the casing top arranges little backing man-like shelf case lid, and the case lid both sides arrange fascia, the casing both sides and and fascia between the grooved ventilation hole is set, lower box arranges entrance hole and wire hole, and disconnecting link, circuit breaker are installed in the casing, and electric power incoming line is connected successively with disconnecting link, circuit breaker.
Described breaker control circuit is; be provided with photoelectric isolating circuit between the electric power incoming line of access and the testing circuit of circuit breaker; between the output of testing circuit and the leakage protection circuit of circuit breaker the relay buffer circuit is set, earth leakage protective circuit output end is connected with the breaking coil of circuit breaker.
Adopt as above the utility model of technical scheme, have following beneficial effect:
The distribution box top cover adopts little backing bi-directional discharging; both sides ventilate; the fascia rainwater-proof enters; can effectively protect the safety of control panel; and by improving circuit breaker; on the basis of electric leakage, short-circuit protection function, increase overvoltage, under-voltage, disconnected zero protection, increased power supply reliability and stability.
