Abstract

A system uses power frequency carrier to control no-fuse breaker. In the system, a controller has a power frequency carrier device. And an other power frequency carrier device is connected with the no-fuse breaker. The two power frequency carrier devices are connected through an indoor power line. The power frequency carrier is sent along the indoor power line so that the controller can remotely control the no-fuse breaker.

Claims

1. A control system of no-fuse breaker using power frequency carrier, comprising:

at least one no-fuse breaker (NFB), said NFB comprising a handling device and a first power frequency carrier device; and

a remote control device, said remote control device having a monitoring-and -controlling device, said monitoring-and-controlling device being connected with a display device and a second power frequency carrier device, said second power frequency carrier device connecting to said first power frequency carrier device through an indoor power line.

2. The control system according to claim 1,

wherein said handling device comprises a switching unit, a trip-switch unit, an over-voltage hand ling unit, a short-circuit handling unit, a over-current handling unit and are set handling unit, said trip-switch unit connecting to said switching unit, said trip-switch unit connecting to said over-voltage handling unit, said short-circuit handling unit, said over-current handling unit and said reset handling unit.

3. The control system according to claim 1,

wherein said monitoring-and-controlling device comprises a manual control unit and an automatic control unit.

4. The control system according to claim 1,

wherein said display device comprises a normal-status light, a trip-switch light, an over-voltage light, a short-circuit light, a over-current light, a reset button and a switch-off button.

5. The control system according to claim 1,

wherein each of said first power frequency carrier device and said second power frequency carrier device comprises a single-chip control module, a power carrier module, a power module, an output controller and an input receiver.

6. The control system according to claim 5,

wherein said single-chip control module comprises an input unit, an output unit, a control unit, a communication interface and a relay.

7. The control system according to claim 6,

wherein said control unit is a 8051 single chip.

8. The control system according to claim 6,

wherein said control unit has a working frequency of 16 megahertz.

9. The control system according to claim 6,

wherein said communication interface is an RS232 interface.

10. The control system according to claim 5,

wherein said power carrier module has a transferring rate of 1200 bits per second.
