Problems solved by technology

[0003] General power cabinets are installed outdoors, most of which are installed on the ground. During heavy rain, rainwater easily enters the inside of the power cabinet. It is inconvenient to detect and maintain the power cabinet at a high place, which not only affects the detection and maintenance of the power cabinet. Efficiency, and the staff are prone to invisible accidents when climbing. In the power cabinet on the ground, the rain on the ground is easy to erode or submerge the bottom of the power cabinet, and the power cabinet is easy to get wet and affect the power equipment inside the power cabinet. It will affect the use of residential electricity
In the cold winter, there will be a large amount of ice and snow gathered on the top of the cabinet, which will cause great pressure on the cabinet. When the pressure reaches a certain level, the cabinet will be deformed or collapsed directly, resulting in power failure. System breakdown and massive losses
In addition, outdoors, due to climate and weather, especially the impact of sandstorms and smog in the north, dust is easy to accumulate in the enclosure of the power distribution cabinet. risks of

Abstract

The invention discloses a high-voltage power distribution cabinet with a multi-protection device and belongs to the field of power equipment. The high-voltage power distribution cabinet with the multi-protection device of the invention discloses a cabinet body; a supporting plate is fixed to the upper side of the cabinet body through supporting columns; a waterproof curtain is arranged around thelower side of the cabinet body; a motor is fixed on the upper side wall of the cabinet body; a first winding wheel and a second winding wheel are respectively arranged on the output shaft of the motor; fixed pulleys are mounted at left and right ends of the lower side wall of the supporting plate; the lifting rope of the first winding wheel penetrates through the left fixed pulley and is connectedwith a lifting ring on the left side of the waterproof curtain; and the lifting rope of the second winding wheel penetrates through the right fixed pulley and is connected with a lifting ring on theright side of the waterproof curtain. Rainproof and waterproof protection can be realized for the power distribution cabinet, so that the influence of rainwater on the interior of the power distribution cabinet is avoided; dust in air can be effectively filtered out, so that the influence of the dust on the power distribution cabinet can be avoided while ventilation and heat dissipation are carried out; and a good ice and snow removing function is achieved, and therefore, the storm and snow resisting capacity of the outdoor power distribution cabinet is greatly improved.

Description

Technical field [0001] The invention relates to the field of power equipment, and more specifically, to a high-voltage power distribution cabinet with multiple protection devices. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The power distribution cabinet is the general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively dispersed and there are few circuits; the motor control center is used in the occasion where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control of the load. [0003] General power cabinets are installed ...
