Abstract
The invention discloses an intelligent control and protection switch, which comprises a casing, a control main board and a relay bottom board. The casing includes connection terminals, indicator lights, digital tube displays and keys; the control main board includes an ARM 32-bit high-speed single-chip microcomputer, a power supply module , signal conditioning module, protection module, drive module, 2-way dry contact output, storage module, human-computer interaction module and communication module; the relay base plate includes a magnetic latching relay and a sampling circuit; the mechanical structure is replaced by an electronic structure, and the switch is closed at the same time The voltage synchronization technology is adopted when the switch is turned off, and the current synchronization technology is adopted when the switch is turned off, which completely eliminates the phenomenon of arcing, thus saving the arc extinguishing device, simplifying the switch structure, greatly reducing the complexity of the equipment, higher integration, and smaller volume. Small and compact, the cost is minimized; using integrated circuit, electronic PCB board technology, SMT automatic placement technology, moisture-proof, high temperature resistance, high reliability, compact space, simple structure.
Description
technical field [0001] The invention relates to the technical field of switches, in particular to an intelligent control and protection switch. Background technique [0002] The traditional CPS (Control and Protection Switch) is a new type of integrated electrical appliance used in the market for the safe and reliable operation of power distribution networks, control systems and motors. It integrates circuit breakers, contactors, starters, and fuses. Control and protection functions. It is mainly composed of base, electromagnetic mechanism, main circuit contact group, auxiliary contact, MCU intelligent control detection system and electronic release system. A considerable part is mechanical structure, which is complex and heavy. Big and expensive. [0003] Therefore, in order to better solve the above problems, it is necessary to develop a device that can integrate most of the functions on the circuit board, and only the contact opening and closing is a mechanical structur...
