Description

technical field

[0001] The invention relates to a switch device for intelligently controlling the on and off of a low-voltage power supply, in particular to a low-voltage switch device with digital protection, automatic control and communication functions, belonging to the field of low-voltage electrical equipment. Background technique

[0002] At present, our country has proposed the concept of developing an intelligent grid, which also includes the intelligence of the low-voltage grid, and the most important part of the intelligence of the low-voltage grid is the intelligence of the low-voltage circuit breaker. The intelligent low-voltage circuit breaker must have digital protection, automatic control and communication functions. At present, our country is moving in this direction. Major professional low-voltage electrical appliance manufacturers and scientific research institutes have done a lot of innovative work, such as Chint's NB7 series electrical appliances, Shangdi...
