CPU in residual current action breaker sets up RS485 and USB communication data interface; can realize long-range, local communication; can carry out data interaction in real time, can realize that also remote operation in time adjusts overcurrent protection value, residual current acting value, operate time of protection.Unite use with low voltage electric network complex automatic system software, can realize remote loads management, save and patrol and examine manpower, reduce operation expense, shorten fault handling time, improve the electricity consumption reliability, improve the good service level.
Description of drawings
Accompanying drawing is the structural representation of the utility model remote monitoring circuit breaker.
Among the figure: 1. watch-dog, 2. communication data interface, 3.CPU, 4. leakage tripping device, 5. moving contact, 6. current transformer loop, 7. zero sequence current mutual inductor loop, 8. electronic on/off switch mechanism, 9. remote system platform.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model remote monitoring circuit breaker is further described.
The local monitor procedure of implementing
The communication data interface 2 that is connected with watch-dog 1 data available line is set on the CPU 3 in the accompanying drawings, its communication data interface shape is that RS485 and USB are provided with respectively, the floor data in current transformer loop 6, zero sequence current mutual inductor loop 7 is when storing local cpu 3 into, can transfer on the watch-dog 1 by communication data interface 2, also can floor data be transferred to remote system platform 9, realize the circuit breaker operating mode is implemented remote monitoring by watch-dog 1.When current transformer loop 6 or zero sequence current mutual inductor loop 7 operating modes occur when unusual, CPU 3 can send the circuit protection instruction to electronic on/off switch mechanism 8, leakage tripping device 4 according to preset program, moving contact 5 is disconnected realize circuit protections.
The remote monitoring implementation process
The floor data of the CPU 3 that reads when watch-dog 1 in the accompanying drawing is transferred to remote system platform 9 by communication data interface 2, can realize remote monitoring.Remote system platform 9 can connect multi-path monitoring device 1; unite use with low voltage electric network complex automatic system software; according to needing of circuit operation; overcurrent protection operating current value in institute's supervisory control system, overcurrent protection action sensitivity value, overcurrent protection value operate time are adjusted in real time; and by remote system platform 9 will adjust the instruction be transferred on the corresponding C PU 3; the management of realization remote loads, and can save and patrol and examine manpower, reduction operation expense, shortening fault handling time, raising electricity consumption reliability.
