Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a power distribution board, and more particularly to a fault indicator of a power distribution board.

[Background of the invention]

Conventionally, as shown in Fig. 1, a voltmeter,
Measuring instruments such as wattmeters and ammeters 2. Fault indicator 3 for displaying faulty items of electrical equipment and systems; operation switch 4 for operating bell/buzzer alarm stop, lamp blinking stop, lamp display return, etc. A relay 5 etc. is installed to detect system trouble. If a failure occurs, the operator will activate alarm stop 4B, flashing stop 4C, and display reset 4.
However, in the conventional failure recovery operation, the procedure was carried out by the operator's memory or by looking at the drawings. Therefore, there are drawbacks such as errors in the operating procedure due to reliance on memory, or the time it takes to study the drawings and understand the operating procedure after a failure occurs, and the time it takes to restore the system.

[Purpose of the invention]

An object of the present invention is to provide a recovery procedure indicator that allows smooth failure recovery operations.

[Summary of the invention]

The key point of the present invention is to provide a repeater procedure display that instructs the operator to take action to recover from the failure when a failure occurs.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

A new recovery procedure indicator 6 is installed near the failure indicator 3 to instruct the operator on failure recovery actions.

For example, when a serious failure occurs, the corresponding failure display item on the failure display 3 flashes, and at the same time, the lamps of the ``major failure'' item 6A and the ``bell stop'' item 6B of the recovery procedure display 6 light up. Then, when you operate ``Stop alarm'' 4B, ``
The lamp for the "stop bell" item 6B goes off, and the item 6c for "stop lamp blinking" lights up.

Next, when you operate [Lamp blinking stop J4C], the corresponding fault display item on the fault display 3 changes from blinking to lit, and "
The item 4c for ``stop lamp blinking'' goes out, and the item 6D for ``failure recovery'' lights up. Therefore.

Go to the site where the failure occurred and work to eliminate the cause of the failure.

When the cause of the failure is removed, the lamp of the "failure recovery" item 6D goes out, and the "rCB unlock" item 6E lights up.

In this way, one operation is performed for each item of the lamp lighting content on the recovery procedure display 6, and finally, [Lamp recovery J4
If you operate F, the corresponding failure display item on the failure indicator 3 will go out, and the "heavy" item 6A and the "lamp return 1st peak 6F" on the recovery procedure display 6 will go out, indicating that the recovery has been completed. show.

Further, the lamp on the recovery procedure display 6 is configured so that the circuit is configured such that the next item is lit under the condition that the operation and work of the previous item are completed, thereby preventing erroneous operation. If you operate and work according to the lighting of the lamp on the recovery procedure display 6, you may accidentally turn off the display and lose track of the failure details, or it may take time and effort to understand the operating procedures from the drawings. To minimize production failures in the event of an accident by eliminating the need for recovery time and facilitating recovery even by inexperienced operators.

〔Effect of the invention〕

According to the present invention, failure recovery operations can be performed smoothly.
