Description

Technical Field

[0001] The utility model relates to the technical field of three-level distribution box equipment, in particular to a three-level distribution box with an emergency power-off button. Background Art

[0002] In order to facilitate the transmission and safe control of electricity, it is often necessary to use distribution box equipment, among which the three-level distribution box is a commonly used one. The utility model patent with patent application number CN202123239591.2 discloses a power distribution box with dustproof function, which can prevent dust from floating in and has certain waterproof performance, providing a better protection structure for internal equipment. The rubber pad and the rubber strip have a greater extrusion force through spring 1. Through this extrusion effect, the sealing of the two is improved, and the internal dustproof and waterproof performance is further improved. The force required to open the door can be controlled by adjusting the elastic force of spring 1. According to the technical solution disclosed by it, the existing three-level distribution box equipment cannot effectively control the working temperature in the distribution box when in use. It is easy to cause the internal temperature to be too high due to the heating of internal electrical appliances and exposure to the sun, which is not conducive to ensuring the working safety of the circuit. On the other hand, when performing ventilation and heat dissipation work, rainwater is easy to enter the inner side of the distribution box through the heat dissipation channel, which is not conducive to ensuring the working safety of the distribution box.
