Description

A durable rainproof and windproof distribution box

technical field

The invention relates to a durable rainproof and windproof distribution box, in particular to a reaction mechanism for detecting the weather environment outside the distribution box.

Background technique

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, constitutes low-voltage distribution equipment, can rely on manual or automatic switch during normal operation. Turn on or off the circuit, cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation, use the measuring instrument to display various parameters in operation, and adjust some electrical parameters to prompt or deviate from the normal working state Signaling, often used in various hair, distribution, and substations. Most of the existing distribution boxes need to be used outdoors. The box body of the distribution box is usually placed directly on the ground, and the ventilation and rainproof function is not good. In wet or rainy weather, rainwater easily seeps into the distribution box, causing the distribution box The electrical components inside are short-circuited and damaged, which affects the normal use of the distribution box. In strong winds, it is easy to blow impurities such as leaves and dust into the distribution box. Once these impurities increase, it is easy to cause the distribution box Short circuit or burning, at present, the top cover of most distribution boxes is still a flat structure, which is not conducive to the discharge of rainwater. With the use of the distribution box, the temperature will gradually increase, which will easily damage the equipment in the box. Ventilation holes have not taken into account the impact of rain and dust, which will damage the electrical appliances, and the existing distribution box is not easy to move and has poor flexibility. It is usually carried by people when moving, which is very inconvenient and cannot adapt to constant In the changing working environment, the box is opaque, and the conditions of the internal components cannot be observed;

Therefore, if the distribution box is made into a rainproof structure, the heat dissipation capacity of the distribution box will be greatly reduced, and the copper heat pipe of the heat pipe heat dissipation structure is easy to corrode due to long-term rainwater immersion, affecting the heat dissipation effect. And the cost of the heat pipe is relatively high;

If the distribution box is made into a good heat dissipation structure, its wind resistance and rain resistance performance will be greatly reduced, which will seriously affect the life of the distribution box and cause a short circuit.

In ZL201220683950.5, a power distribution box with both heat dissipation and waterproof performance is mentioned, which mainly includes a power distribution box body, a power distribution box cover and a power distribution box door. The door of the electric box is set on the side of the distribution box, and the bottom of the distribution box is provided with a cooling hole, and a heat dissipation pipe is arranged under the cooling hole; the structure is mainly to realize the heat dissipation inside the distribution box through the heat dissipation pipe, and the heat dissipation pipe generally adopts contact In order to dissipate heat, the original structure of the distribution box needs to be greatly modified, and the cost is high. Moreover, many electrical components in the distribution box are different from the heating parts in the computer, and they are not high heat flux heating objects. The electrical components in the box generally generate heat toward the surroundings. The efficiency of the contact heat exchange heat pipe heat dissipation and the heat dissipation capacity obtained by the unit price are very low, and because the equipment is a fully sealed structure, once the water vapor passes through the distribution box After the gaps and cooling holes penetrate into the distribution box, it is difficult to dissipate, and it will accumulate in the distribution box, causing a short circuit;

Another example is a rainproof and ventilated distribution box proposed in ZL201420149065.8, which mainly provides heat dissipation through a rainproof cover and some one-way heat dissipation components, but this structure can only prevent small precipitation. Big, the one-way cooling fan is difficult to block the entry of rainwater, and this structure needs to keep the fan working frequently, which brings great noise and waste of energy.
