Description

A distribution box with waterproof and moisture-proof function

technical field

The utility model belongs to the technical field of distribution boxes, in particular to a distribution box with waterproof and moisture-proof functions.

Background technique

The distribution box is a box that integrates electrical components for power distribution. The function of the distribution box is to distribute and control the electrical equipment. When the circuit is overloaded, short-circuited or leaked, the distribution box can also Provide power-off protection. The power distribution box mainly distributes and controls electrical equipment. It also provides power-off protection when the circuit is overloaded, short-circuited or leaked. When the line fails, it is convenient and quick to control the fault range. Find out the fault point and eliminate it in time without large-scale power outage. Various protective devices such as fuses to prevent short circuit and air switches to prevent overload can be placed in the distribution box, which can protect the lines and electrical equipment, which is convenient. Maintenance and inspection, in order to ensure the internal heat dissipation effect of the distribution box and maintain the normal operation of electrical components, there are generally louver ventilation windows with openings facing down on both sides of the distribution box body, which are used for ventilation and heat dissipation of the internal electrical components. And in rainy weather, the opening of the louver ventilation window is facing downward, although it can effectively prevent rainwater from entering the box, but in rainy weather accompanied by strong winds, some water vapor will also enter the distribution box with the wind, resulting in a short circuit of the equipment. Accelerate the aging of electrical components, affect the normal operation of equipment, and easily cause safety accidents.

Preferably, exhaust holes are equidistantly arranged on the outer side of the joint between the top cover and the box body.

Preferably, the air intake device includes at least an intake fan, a dust-proof net and an arc-shaped waterproof cover with an opening downward.

Preferably, at least a door lock and a display are arranged on the lock seat, and the moisture detector is electrically connected to the display.

The technical effects and advantages of the utility model: the power distribution box with waterproof and moisture-proof function is equipped with a humidity sensor inside the box body, which is convenient for reading the internal humidity data, and at the same time, it is supported by a mesh support plate and is composed of a silica gel desiccant and a heater. The silica gel drying heater and negative pressure fan drive the air flow inside the box to absorb the moisture inside the box, which is not only easy to install, but also can heat the silica gel desiccant through the heater to prevent the silica gel desiccant from being saturated Stop moisture absorption, the negative pressure fan on the top cover of the trapezoidal hollow structure and the air intake device form a circular exhaust, which greatly maintains the dryness inside the box and forms a waterproof structure. This device prevents rainwater from entering the box and circulates A heat dissipation channel is formed on the structural baffle, which has a good heat dissipation effect, is waterproof and moisture-proof, and is conducive to the stable operation of the internal components of the box. The load hole design is convenient for loading and unloading, and improves the safety of electrical appliances.
