Low-voltage control electric appliance for building electrical design and fault detection method

Abstract

The invention discloses a low-voltage control electric appliance for building electrical design and a fault detection method. The low-voltage control electric appliance comprises a low-voltage electric appliance cabinet shell, wherein a cabinet door is hinged to the front end of the low-voltage electric appliance cabinet shell; an air switch which is installed at the front end of the cabinet door, wherein a warning board is arranged below the air switch; an electric appliance installation bin which is installed in the low-voltage electric appliance cabinet shell, wherein clamping grooves which are evenly distributed at equal intervals are formed in the left wall and the right wall of the electric appliance installation bin, and an installation plate is arranged in the electric appliance installation bin. Compared with an existing device, the low-voltage control electric appliance for building electrical design and the fault detection method have the advantages that the low-voltage electric appliance elements can be mounted and placed in a classified manner through the arranged electric appliance mounting bin, the position of the mounting plate in the electric appliance mounting bin can be changed according to needs, a user can freely match the mounting plate, and meanwhile, the internal space of the electric appliance mounting bin is saved; and through holes are formed in the mounting plate, so that air can freely circulate, and the heat dissipation performance in the low-voltage electric appliance cabinet shell is improved.

Description

technical field [0001] The invention relates to the technical field of low-voltage control appliances, in particular to a low-voltage control appliance for building electrical design and a fault detection method. Background technique [0002] A low-voltage electrical appliance is a component or device that can switch, control, protect, detect, transform and adjust circuits or non-electrical objects by manually or automatically switching on and off circuits according to external signals and requirements. Control electrical appliances can be divided into high-voltage control electrical appliances and low-voltage control electrical appliances according to their working voltage, with AC 1200V and DC 1500V as the boundary. Generally speaking, low-voltage electrical appliances can be divided into two categories: power distribution appliances and control appliances, which are the basic components of complete sets of electrical equipment. In industry, agriculture, transportation, n...
