Abstract

PROBLEM TO BE SOLVED: To increase packaging density and working efficiency, by fixing a partition rack for separating the inside of a panel into front and rear or right and left parts on both inner side faces of the panel, and installing an opening and closing doors on a front face and a rear face for allowing equipments to be mounted from the front and rear sides using the partition rack. SOLUTION: A box type control panel has doors 2-1, 2-2 on a front and a rear faces of a box 1. These doors make it possible to work from both front and rear sides. Furthermore, a partition rack 7 installed at the center inside the panel is used for mounting equipments such as control units and electric components on both sides of it. Wires 5 from the control units 3 and the like are put in order at wire receivers 6 and then are led out to a cable duct 9. Since the front and the rear face of the case 1 can be opened at least while at work and the partition rack 7 for separating the inside of the case into two sections is installed and its front and the rear face are used for mounting, the mounting density can be remarkably increased and the working efficiency can be also increased as the work can be done from the front and rear sides.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box-type control panel of a control device, and more particularly to a panel structure that can improve the storage density of equipment and work efficiency.

[0002]

2. Description of the Related Art FIG. 2 shows a configuration example of a conventional box-type control panel. The housing 1 of the box-type control panel is used for mounting electric components and the control unit 3 with the three sides of both sides and the back as fixed walls,
A movable door 2 is provided on the front surface for mounting and maintenance. When the mounting area in the panel is insufficient, the back surface of the door 2 may be used. In the panel, a space enough for one worker to enter is secured, and mounting and maintenance of the equipment including the rear surface are enabled. The control unit 3 has individual functions, and is a unit formed by combining several control modules of about A5 size and attaching them to one board (substrate). Wiring 4 is external cable, panel cable,
It is classified as inter-panel cable, and there are about 200 wires per panel.

FIG. 3 schematically shows a turbine control apparatus having a four-panel configuration. (A) is AA sectional drawing, (b) is a front view. From left: Generator control panel (mainly protection relay 1
8, auxiliary PT / CT20), generator auxiliary panel (same as the left), turbine control panel (mainly control unit 3
), And a turbine auxiliary panel (mainly mounted with a relay 19 and a terminal block 21 for wiring relay). The external dimensions of each panel vary, and are determined by the equipment to be mounted and the working space, and require different sizes of housing for each application. By the way, when a typical example of the dimensions of this row board is shown in millimeters, the width is 700, 900, 914 and 700 from the left, the height is 2286, and the depth is 914.

[0004]

As described above, since the conventional box-type control panel has the rear and both sides fixed and the equipment is mounted, the operator enters the panel during mounting and maintenance and works. I had to. For this reason, it is necessary to secure a work space inside the board after mounting, which is wasted space, lowering the mounting density, increasing the board size and the number of boards, and causing a problem in securing the installation area. There were many. In addition, work efficiency is low because work in the panel is limited to one person,
There was a problem that the work schedule was lengthened.

An object of the present invention is to provide a box-type control panel having a structure which can overcome the problems of the prior art and can improve the mounting density and work efficiency.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a box-type control panel in which devices such as units having electric parts and control functions are arranged.

The apparatus is configured such that the front positions of the devices to be mounted on the second surface in a plurality of stages can be aligned. According to this, the display at the front of the device is easy to see, and adjustment and wiring between the devices are also easy.

As another embodiment, in a case where the first surface of the aligned L-shaped member is fixed to a side surface in a board and the device is mounted on a second surface, the L-shaped member in the front row is provided. A wiring space is provided at a position facing the rear row so that units requiring back work can be arranged on the second surface of the character-shaped member. According to this, wiring of a TB and a connector provided at the rear of the device can be performed from behind.

Also, a plurality of mounting plates for mounting the units are provided in the height direction between the second surfaces of the L-shaped member, and a wiring receiver for collecting the wiring of the units of each stage is provided between the stages. Is provided. Further, at the lower end of the mounting plate, or at the lower end integrally configured with the mounting plate and the wiring receiver,
An air passage plate that engages with the row internal space formed by the tying structure, and is configured such that cooling air flowing from the lower part of the panel into the internal space can be introduced into the lower part of the unit by the air path plate of each stage. I do. This facilitates wiring in the panel and improves the cooling efficiency of the unit in the panel.

Further, a part or the whole of the mounting plate is installed on the partition so as to be openable and closable. As a result, not only the wiring work of the backside wiring type device is facilitated, but also the wiring can be arranged using the internal space of the tying structure, so that the mounting density can be improved.

Is opened, and the back-side wiring type electrical components 4-1 and 4-2 whose mounting sides serve as wiring ports are mounted, and then closed, and the other end is fixed to the partition frame 7 by the knurls 26.

According to this, the wires 5 from the electric components 4-1 and 4-2 are drawn into the internal space 10, and can be collectively drawn out in the hinge direction toward the upper / lower direction of the partition frame 7, so that the internal space is effectively used. Wiring is easy, and the mounting efficiency can be improved. Note that there are modifications such as providing a movable mounting plate on the entire surface of the partitioning frame 7 to form an integrally open configuration.

While a plurality of embodiments of the box-type control panel characterized by the tying structure have been described above, various modifications such as combinations and exchanges between these embodiments, and exchange of the front / rear sides are possible. Further, the partition frame can be fixed to the upper and lower surfaces of the housing instead of the side surfaces. In this case, the partitioning frame may be provided so as to partition the inside of the panel not right and left but left and right. Further, the installation of the door on the front / back side is an optimal embodiment, but only one may be provided. In short, it is only necessary that the front / rear can be opened at the time of work, and it is not limited to the door.
