Power distribution cabinet with fault alarm function

Abstract

The invention discloses a power distribution cabinet with a fault alarm function, relates to the field of electrical equipment, and provides the following scheme for solving the problems that most of existing power distribution cabinets are lack of alarm devices, have more lines, do not have a moisture-proof function and are easy to cause dangerous accidents. The power distribution cabinet comprises a case shell, wherein a ventilation layer is arranged on the inner side wall of the case shell, the bottom end of the inner side of the ventilation layer is fixedly provided with three branch circuit breaker sets of the same structure, the branch circuit breaker sets are transversely connected with first fault lamps and vertically connected with second fault lamps, and the upper end, close to the branch circuit breaker sets, of the case shell is fixedly provided with a main circuit fuse set. According to the invention, the power distribution cabinet is additionally provided with an alarm function and an exhaust heat dissipation function, saves energy consumption, and is provided with multiple fault prompting devices, and an alarm system performs detection in a segmented mode, so that the positions where faults are located are effectively judged; and the power distribution cabinet not only has safety and multifunctionality, but also is more practical and suitable for popularization.

Description

technical field

[0001] The invention relates to the field of electrical equipment, in particular to a power distribution cabinet with a fault alarm function. Background technique

[0002] At present, in the field of electrical equipment, power distribution cabinets are necessary basic equipment. 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 ...
