Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for mounting monitoring and control equipment on a monitoring surface of a switchboard.

Traditionally, display elements such as meters and lamps were placed on the monitoring surface of the switchboard.
There is a method shown in FIG. 1 for installing monitoring and control equipment consisting of control elements such as operating elements such as switches and protective relays. In Figure 1, (1) is the main body of the switchboard, (2) is the door that is the monitoring surface of the main body, (3) to (9) are the monitoring and control equipment attached to this door, and (3) is the ammeter, (4) are protective relays such as overcurrent relays and ground fault relays, each of which has an operating status display section. (5) is a power meter, (6) is an ammeter phase changeover switch, (7) is a test terminal, (8) is a breaker control switch, and (9) is an alarm indicator lamp.

In this way, the conventional switchboard has an ammeter (3) and a wattmeter (5).
), display devices such as lamps (9), control devices such as protection relays (4), and operating devices such as changeover switches (6) and control switches (8), each with a door (2).
and when attaching the above appliance to the door (1),
The placement dimensions were determined, and holes were made in the door (1) according to the size of each device to install it. Therefore, when the type, size, number, etc. of display devices and operating devices change depending on the function, it is not only necessary to replace those devices, but also to review the placement of each device, change the hole opening (panel cut) in the door, and make major changes to the wiring. It became necessary to manufacture many types of doors. Another disadvantage is that a space is required on the back side of the door to accommodate the embedding of the instrument.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and by integrating the monitoring and control equipment into an assembly panel, it is easy to make holes in the monitoring surface, and the door, that is, the back surface of the monitoring surface, can be easily punched. It is an object of the present invention to provide a mounting device that can eliminate the space required for the.

An embodiment of the present invention will now be described with reference to the drawings. Second
In the figure, (1) is the switchboard main body, (2) is its door, α
Q is a collection panel attached to the front surface of the door (2), which is the monitoring surface, with screws or the like, and a specific example of its configuration is shown in FIG. 8, in which monitoring and control equipment is integrated.

In Fig. 8, the voice is a collective panel, which is composed of a single panel-shaped box. (b) is the indication display section of the ammeter;
@ is the power needle instruction display section, (to) is the power amount needle instruction display section, (14 is the status display section that displays the operation of the circuit breaker on, off, trip, etc. and the operation of the protective relay, (
2) is an alarm display section, and the display sections α9 to α9 constitute display elements necessary for monitoring. Qle is an operation switch of a control circuit that controls closing and tripping of the breaker, and (B) is a phase changeover switch of an ammeter, which together with the above-mentioned operation switch (To) constitutes an operation element. The display elements (lυ~ (to)) and the operation elements (2) and (2) are housed in a single panel-like box, that is, as a unit. (to) is inside the switchboard. (2) is the device side plug that electrically or optically connects the equipment and the internal circuit of the assembly panel H. (2) is the equipment side plug, and both constitute a connection plug. (E) is the panel side plug that electrically or optically connects the equipment and the internal circuit of the assembly panel H.
The holes (2) provided at the four corners of are bolts that are inserted into the holes (E) to secure the assembly panel 01 to the door (2), which is the monitoring surface.

Here, each of the display sections (b) to (g) is composed of a non-mechanical element such as a light emitting diode, a liquid crystal, an electroluminescent display, a plasma display, a fluorescent display tube, and a CRT. In addition, instruction display sections (b) to (2)
may be an analog display or a digital display. Note that the measuring section of the measuring meter in the instruction display section α~(to) is computerized to make it smaller and thinner. Furthermore, the main body of the protective relay may be separated from its status display section (b) and attached to the breaker side, but if it is to be miniaturized, it may be housed in this collective panel aQ.

In such a configuration, several types of assembly panels (A) are prepared so that they can be applied to any pattern, and their external dimensions, mounting dimensions, and connection plug positions are the same. Figure 4 shows the assembly panel (to). This figure shows the front of the switchboard to which the front door (2) is installed, and the front door (2), that is, the monitoring surface, has mounting holes on four sides corresponding to the holes of the collective panel QΦ, and connection plugs (to). A plug extraction hole (2) is provided at a position corresponding to (6). Therefore, the number of holes on the monitoring surface is much smaller than that of the conventional method.If the mounting dimensions of the collective panel and the connection plug position are the same, the mounting holes (2
), the position of the plug draw-out hole (to) may be the same, and the position of the plug draw-out hole (to) may be the same, and
There is only one type of ``, and there is no need for multiple types.

Figure 5 is a side view of the assembly panel (6) shown in Figure 8 attached to the door (2) shown in Figure 4;
Insert the bolt (2) into the hole (E) and the mounting hole (2) of the door (2).
The assembly panel QQ is fixed to the door (2) by passing a nut through the bolt and screwing a nut onto the bolt from the back side of the door (2). In this case, the panel side plug (
(g) is penetrated and connected to the device side plug (2) connected to the devices inside the switchboard.

In addition, although the above-mentioned embodiment shows a case in which there are four mounting holes and - number of holes in the plug extraction hole, it is also possible to have a plurality of mounting holes and a plurality of holes in the plug extraction hole. Also, the mounting position may be the front panel of the breaker instead of the door if the collective panel containing the monitoring and control equipment is mounted on the monitoring surface. The connection line from the connection plug may be an optical fiber.

In addition, although Fig. 4 and Fig. 6 are explained using an example of the mounting method using bolt tightening, the mounting method may be a hook type, a metal type, a presser foot type, a hinge type, an adhesive type, etc. in the above embodiments. It has the same effect as.

As described above, according to the present invention, the monitoring and control equipment can be assembled and mounted on an integrated panel, and the monitoring surface corresponding to the plug position can be machined, for example, holes in the door, making it easy to process the door. This makes it easier to replace monitoring and control equipment. Further, there is an effect that the space on the back side of the door due to the embedded part of conventional monitoring and control equipment is no longer required.
