Abstract
The invention discloses an outdoor power distribution box with waterproof and ventilation functions. The outdoor power distribution box is characterized by comprising a box body, wherein a box door is arranged at the front side of the box body; a small ridge A-bracket box cover is arranged at the top of the box body; weather boards are arranged on two sides of the box cover; trough type air holes are formed between two sides of the box body and the weather boards; a wire inlet hole and a wire outlet hole are formed in the lower part of the box body; a disconnecting link and a breaker are arranged in the box body; a power inlet wire is sequentially connected with the disconnecting link and the breaker. The top cover of the power distribution box adopts a small ridge to exhaust in two ways and to ventilate from two sides; the weather boards are used for preventing rainwater from entering; the safety of electric control equipment can be effectively protected; over-voltage, under-voltage and faulted neutral line protection can be added on the basis of electric leakage and short circuit protection functions through improvement of the breaker; the power supply reliability and stability are increased.
Description
Technical field
The present invention relates to a kind of outdoor distributing box with water-proof ventilation function.
Background technology
Existing distribution box top is flat cover; impeded drainage, has water storage phenomenon, venetian blind type louvre; entering of various wind direction rainwater can not be stoped; distribution box inner air flow is not smooth, causes control panel heat not discharge in time, easily burns control panel; and the protective switchgear in low-tension distribution box; only possess electric leakage, short-circuit protection two kinds of functions, in actual motion occur " fault off zero ", or there is overvoltage, under-voltage time can not play a protective role.
Summary of the invention
For solving above-mentioned existing shortcoming; main purpose of the present invention is the outdoor distributing box with water-proof ventilation function providing a kind of practicality; distribution box top cover adopts little backing bi-directional discharging; both sides ventilate, and fascia rainwater-proof enters, the safety of energy available protecting control panel; and by improving the carrying out of circuit breaker; on the basis of electric leakage, short-circuit protection function, increase overvoltage, protection under-voltage, off zero, add power supply reliability and stability.
For reaching above-described object, following technical scheme taked by a kind of outdoor distributing box with water-proof ventilation function of the present invention:
A kind of outdoor distributing box with water-proof ventilation function, it is characterized in that, it comprises casing, described cabinet front arranges chamber door, casing top arranges little backing man-like shelf case lid, case lid both sides arrange fascia, casing both sides and and fascia between grooved ventilation hole is set, lower box arranges entrance hole and wire hole, in casing, disconnecting link is installed, circuit breaker, electric power incoming line and disconnecting link, circuit breaker connects successively, described circuit breaker control circuit is, photoelectric isolating circuit is provided with between the electric power incoming line of access and the testing circuit of circuit breaker, relay buffer circuit is set between the output of testing circuit and the leakage protection circuit of circuit breaker, earth leakage protective circuit output end is connected with the breaking coil of circuit breaker.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Distribution box top cover adopts little backing bi-directional discharging; both sides ventilate; fascia rainwater-proof enters; the safety of energy available protecting control panel; and by improving the carrying out of circuit breaker; on the basis of electric leakage, short-circuit protection function, increase overvoltage, protection under-voltage, off zero, add power supply reliability and stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is circuit breaker control circuit theory diagram of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of outdoor distributing box with water-proof ventilation function of the present invention, it comprises casing 1, arrange chamber door 2 on front side of described casing 1, casing 1 top arranges little backing man-like shelf case lid 3, and case lid 3 both sides arrange fascia 4, casing 1 both sides and and fascia 4 between grooved ventilation hole 5 is set, casing 1 bottom arranges entrance hole 6 and wire hole 7, and be provided with disconnecting link 8, circuit breaker 9 in casing 1, electric power incoming line 10 is connected successively with disconnecting link 8, circuit breaker 9.Circuit breaker control circuit is; photoelectric isolating circuit is provided with between the electric power incoming line of access and the testing circuit of circuit breaker; arrange relay buffer circuit between the output of testing circuit and the leakage protection circuit of circuit breaker, earth leakage protective circuit output end is connected with the breaking coil of circuit breaker.
