JPH0728670Y2 - Sliding plate for handle operation of multiple circuit breakers - Google Patents

Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is intended to prevent the operation of a circuit breaker other than the circuit breaker to be operated by a plate which slides the handle operation of two or more circuit breakers left and right. In the mechanical interlock device, the sliding plate is a transparent plate.

[0002]

2. Description of the Related Art In a mechanical interlock device for a circuit breaker, an opaque plate is conventionally used as a sliding plate. Therefore, a nameplate indicating the type, rating, etc. of the cover surface of the circuit breaker is displayed. However, it was hidden by this sliding plate and the display could not be read. The mechanical interlock device of the circuit breaker is one that has been used for a long time.In the event of a power outage, such as switching from a power generator that is always working to an emergency generator, when both are not working at the same time, It is a device that locks.

[0003]

For this reason, it is inconvenient to read by using various means such as lifting or warping the sliding plate by one hand.

[0004]

Means for Solving the Problems In consideration of this point, the present inventor has conducted various trial manufactures and experiments, and has found that a good result can be obtained by using a plate such as a transparent synthetic resin. In other words, by using a transparent plate, the display on the cover surface can be read through this plate, and the model and rating of the circuit breaker can be easily discriminated.

[0005]

Thus, in the present invention, by using the transparent plate as the plate that slides the handle of two or more circuit breakers to the left and right, the model and rating of the cover surface can be easily read as it is. The effect of being easy to handle is great.

1 is a front view of a circuit breaker using a sliding plate of the present invention, and FIG. 2 is a side view of the same. In the figure, 1a and 1b are separate circuit breakers, but they are operated by one sliding plate 2. Also, 3a and 3b are the respective circuit breakers 1
It is a nameplate displayed on the cover surface of a and 1b, and shows the model, rating, and other indications. The other 4 is an interlock device for preventing the operation of circuit breakers other than the circuit breaker to be operated, but since it is well known and is not directly related to the present invention, its structure will not be described. Omit it. Here, in the present invention, the sliding plate 2 is a transparent plate.

[0007]

As described above, in the present invention, by using the transparent plate as the sliding plate 2 as described above, it is possible to easily and easily display the nameplates indicating the model and rating of the surface of the cover of the circuit breaker. It can be read.
