Abstract

The electrical distribution switchboard can be controlled remotely via an operating switch. A remote that can realize and control the operation, turn on and off the power supply to the device. Electrical appliances In which the switchboard consists of a main circuit breaker Number breaker One to supply electricity to the relay When the relay operates, there is an electric current through its contacts. Of relays to supply to electrical appliances But the relay will work depending on the command from Remote switch This sends a command signal to the control board in the control unit to receive commands and supply power to the relay coils. To make the relay work and have a direct switch to supply electricity Direct relay coil When the control board is faulty, it cannot be operated from the remote switch.

Claims (5)

1.Electrical distribution switch panel can be controlled remotely via a remote switch. It is characterized by a main circuit breaker (5) for connecting the external mains to the distribution switchboard (1) and power through a copper plate (6) to a number of circuit breakers (4) to supply current through the line. Electricity (9) comes to a number of relays (3) to act on and off the power supply through wires (10) to electrical appliances (11), relays (3) to enable or disable the distribution of electricity. When power is supplied to the relay coil (3) from the control module (2) through the signal wire (16), the control module (2) consists of a control board (13) that receives commands from the remote switch. (19) which is an external device of this invention Through the signal wire (18) and performs the data processing function to instruct the relay (3) to open or close the power supply. The control board (13) receives power from the transformer (12) and has a switch (17) as an on-off switch. Current into the transformer (12) In the event that the control board (13) does not work, it can be operated at the direct-connected switch (14) through the signal line (15) to the signal line (16) to run the relay (3). 2.Electrical distribution switch panel remotely controls the power Through the remote operation switch according to claim 1, where the control unit (2) is located within the power distribution switchboard (1). 3.Electrical distribution switchboard remotely switches on and off electricity via a remote switch in accordance with claim 1, where the relay (3) is located inside the distribution switchboard (1). 4. Power distribution switchboard remotely control power on and off via a remote switch. According to claim 1, where the control board (13) consists of a power supply (20) for powering various devices. On the control board, the link unit (21) receives the signal. Operate from remote actuators outside the power distribution switchboard (1) to convert and broadcast signals. Data to the processor (22) calculates and directs the relay drive unit (24) to supply power. Enter the relay coils (3) with the storage unit (23) remembering the last action from the processor (22). 5. The power distribution switch panel can be controlled remotely via the remote switch. According to any one of the 1 to 5 claims Can be used with a power distribution switchboard (1) that is a pressure system. AC power 220 volts or 380 volts.
