Field power distribution cabinet suitable for emergency maintenance in rain and snow weather

Abstract

The invention discloses a field power distribution cabinet suitable for emergency maintenance in rain and snow weather, which comprises a cabinet body and supporting legs, and is characterized in that the bottom end of the cabinet body is uniformly provided with a plurality of supporting legs, an inner cavity of the cabinet body is provided with a partition board, the partition board separates the inner cavity of the cabinet body into a maintenance chamber and an operation chamber, the top wall of the operation chamber is provided with an exhaust fan, the middle part of the front end face of the maintenance chamber is hinged with a first cabinet door, the first cabinet door is provided with a first handle and a first mechanical door lock, the bottom part of the maintenance chamber is provided with a pedal plate corresponding to the bottom end face of the first cabinet door, the inner side of the top end of the pedal plate is provided with a shoe box, the rear side wall of the maintenance chamber is provided with a shutter, the middle part of the partition board is hinged with a second cabinet door, and the second cabinet door is provided with a second handle and a second mechanical door lock. According to the invention, the field power distribution cabinet is provided with two chambers such as the maintenance chamber and the operation chamber, and the second cabinet door of the operation chamber is arranged in the maintenance chamber, so that external dust, rain and snow can be effectively prevented from getting into the operation chamber. The setting of the maintenance chamber can ensure the emergency maintenance personnel to perform emergency maintenance in the rain and snow weather, thereby ensuring the maintenance work to be performed smoothly.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a field distribution cabinet suitable for emergency repairs in rainy and snowy weather. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions 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 nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] The door of the existing power distribution ca...

AI Technical Summary

Problems solved by technology

[0003] The door of the existing power distribution cabinet cannot completely seal the entire power distribution cabinet body, and a certain amount of floating dust will enter after long-term storage, especially some power distribution cabinets with a clear gap between the cabinet door and the cabinet body. When the temperature is high, it is easy to accumulate a large amount of floating dust in the cabinet cavity, which will cause the components to be wrapped by the floating dust and cannot dissipate heat, which will affect the normal operation of the components. If the gap enters the cabinet cavity, the internal components will be short-circuited and burned out, which will affect the normal operation of the equipment; once the power distribution cabinet installed in the field is damaged in the rain and snow, the repair personnel cannot directly open the cabinet door for repair, otherwise the rain and snow will directly Enter the electrical cabinet through the door hole of the cabinet, and then burn out the entire power distribution cabinet, which greatly hinders the normal maintenance of the power distribution cabinet and affects the normal operation of the entire power grid
