Non-contact switch low-voltage distribution apparatus with monolithic apparatus

Abstract

The present invention relates to a non-contact switch low-voltage distribution apparatus with monolithic apparatus which is composed of a host machine, a switching control device, a system power supply, an input, output and communication interface, a system power supply, a display screen as well as a minitype manual control dot printer. The host machine is composed of a single chip microcomputer and the switching control device comprises a gate circuit transistor electronic contactless switch. By adopting the low-voltage distribution device of the utility model as the technical innovation of the 0.4KV-grade distributed system and the commodity after the replacement of the older generation by new ones, the non-contact switch low-voltage distribution apparatus with monolithic apparatus applies the modern advanced microcomputer technology and the digital information technology to deal with the overtop data acquisition and arithmetic for each item of the power utilization parameter of the power utilization system and to carry out general surveillance, control, protection, etc. The non-contact switch low-voltage distribution apparatus with monolithic apparatus has the functions of continuous displaying, automatic metering, automatic protecting, automatic controlling, etc.

Description

technical field [0001] The invention relates to a low-voltage power distribution device of a power system, in particular to a low-voltage power distribution device with functions of digital information management, microcomputer real-time monitoring and thyristor electronic non-contact switch. Background technique [0002] The power industry is an important technical industry and public utility that is related to the national economy and the people's livelihood. It is the means of production of all walks of life and the means of living that are closely related to people's lives. The safety of power supply is closely related to social stability and people's lives. Objectively speaking, modern power supply requires safety and reliability. On the basis of reasonable grid structure and advanced technology, through strengthening management, improving the management level of the grid, increasing the ability to control the large grid, ensuring the safe and stable operation of the gri...

AI Technical Summary

Problems solved by technology

The current power supply and distribution system of my country's power system uses current relays for overcurrent protection, thermal relays and contactors for protection and operation, pointer mechanical meters for metering instructions, and mechanical meters for power metering, etc. , technical facilities are backward, seriously restricting the development of electric power

For example, my country has experienced power shortages since last year. There are 19 provinces and cities across the country that have limited power, and the management of power loads can only be done once an overload occurs. It has had a serious impact on industrial and agricultural production and people's lives.

At present, the power distribution technology in the world is also lagging behind. For example, the 8.14 blackout in North America in 2003 was caused by outdated power supply lines and backward power supply equipment technology.

After the blackout accident, it was out of control, causing 50 million people without power, and the economic loss was immeasurable
