Field bus type intelligent low-voltage switchgear

Abstract

The embodiment of the invention provides field bus type intelligent low-voltage switch equipment. The field bus type intelligent low-voltage switch equipment comprises a low-voltage switch cabinet, a field bus module; the field bus module is connected with the communication bus, and the communication bus is used for transmitting information collected by the field bus module and feeding back a control instruction to the field bus module; and the communication bus is connected with the processor, and the processor is used for receiving the information acquired by the field bus module and transmitted by the processor, processing the information and feeding back the information to the field bus module for processing through the communication bus. According to the embodiment of the invention, remote and automatic control is realized through transmission of the communication bus and processing of the processor, and good economic benefits and remarkable social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of low-voltage switchgear, in particular to a fieldbus type intelligent low-voltage switchgear. Background technique [0002] As the name implies, low-voltage switchgear is a device that connects low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then sent to low-voltage cabinets. Assemble some protection devices such as switch circuit breakers into an integrated electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each sub-circuit is set according to its needs, such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., and some are also equipped with high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc., and some are also equipped with low-cycle load sh...

AI Technical Summary

Problems solved by technology

[0003] The use of low-voltage switchgear is very extensive. It plays a very important role in our life and work. The existing low-voltage switchgear is configured in the form of separation of distribution and control, and its functions are relatively single. Generally, it can only complete power receiving, distribution Combined functions such as output, motor power control and protection, etc., and the functions of contactor pull-in and breaking for motor power control need to be completed by a special control system

The low-voltage switchgear integrated with distribution, control and integration developed on this basis can complete the functions of control, detection, and fault status alarm for the control object, but it can only be completed under wired conditions and cannot meet the existing requirements. The requirements of the wireless working environment
