Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a circuit breaker, and more particularly to a circuit breaker that enables energization display of load equipment connected to the secondary side and identification display of energized equipment. .

(Prior art and its problems) In a conventional circuit breaker, even if a load device connected to the secondary side is energized, the circuit breaker itself cannot confirm.

Well, this circuit breaker is simply the O switch.
By displaying N or OFF, it only indicates that power can be supplied to the secondary side, and does not indicate whether or not the load equipment actually connected to the secondary side is energized. Since there is no display, there is a problem that the operator may accidentally turn off the switch and destroy data on the computer, etc.

In order to prevent such accidents, it is necessary to check the operating status of each connected load device, but since the circuit breaker and load device are often installed at a distance from each other, it is necessary to check the operating status of each connected load device. Checking whether each load device is in the same state is extremely complicated work.

(Means for Solving the Problems) The circuit breaker of the present invention supplies current received from a power source to a plurality of load devices, automatically interrupts the circuit when the current exceeds a predetermined value, and In a circuit breaker having a switch means for stopping the supply of current, a plurality of load connection means are provided between an output terminal of the switch portion and an output terminal for the load device, respectively corresponding to the load device. , detection means for detecting which load connection means actually supplies current among the load connection means;
and display means for displaying information regarding the load connection means detected by the detection means.

(Example) Next, a circuit breaker of the present invention will be explained with reference to the drawings.

FIG. 1 is a block configuration diagram of an embodiment of the present invention, which includes a switch section 1 and an energization/pulse code detection section 2.
It consists of a display section 3 and load connection sections 48 to 4E.

The switch unit 1 supplies current from the input power source to the loads and devices 5A to 5E connected to the secondary side, and when the current reaches a predetermined value or higher, it automatically cuts off the circuit and stops supplying the current. stop. Moreover, this switch section 1 can be turned on or off.
The F display indicates whether or not it is possible to supply power to the secondary side.

The load connection parts 4A to 4E connect the connected loads 1 and 5A to 4E.
5E respectively. Each load connection part 48-4
Different pulse codes P1 to P are assigned to E in advance, and when the power is turned on, the pulse codes are sent to the power supply line.

The energization/pulse code detection unit 2 receives various pulse codes P1 to P sent through the power supply line L1.

The load equipment 5A to 5E is identified and detected according to the detection result.
Information indicating which of them is in the energized state is sent to the display section 3.

Upon receiving this information, the display section 3 turns on a lamp corresponding to the specific load machine 64A or 4B, which is in the energized state.

According to the above embodiment, the load device 5 connected to the secondary side
You can tell which device from A to 5E is powered on by the blinking lamp on the display 3, so you can avoid accidentally turning off the circuit breaker switch while using a computer, for example.
It is possible to prevent harmful effects such as data destruction. Further, even if the circuit breaker and the load devices 5A to 5E are located far apart, it is possible to specify which device is energized, so there is no need to check each device individually.

(Effects of the Invention) As explained above, the present invention provides an energization display for the load equipment connected to the secondary side and an identification display for the energized equipment, thereby preventing users from accidentally activating the circuit breaker while using the load equipment such as a personal computer. In addition to preventing the harm caused by switching off the switch, you can immediately identify which devices are energized by looking at the display, so you can easily identify the location where each device is placed to understand the operating status. This greatly simplifies the work by eliminating the need to go to the office and checking only the operating status of devices that display energized status.

Claims (1)

[Claims] The current received from the power supply is supplied to multiple load devices, and when the current exceeds a predetermined value, the circuit is automatically cut off.
In a circuit breaker having a switch means for stopping the supply of current, a plurality of load connection means are provided between the output terminal of the switch section and the output terminal for the load equipment, respectively corresponding to the load equipment; It is characterized by comprising a detection means for detecting the load connection means actually supplying current among the load connection means, and a display means for displaying information regarding the load connection means detected by the detection means. circuit breaker.
