Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved anti-corrosion control panel that facilitates installation work and prevents corrosion of control equipment from the adverse environment at the installation site.

Conventional building construction methods take a relatively long construction period and avoid duplication of construction.

For this reason, even when electrical equipment is installed on-site, it is done at a time when dust, moisture from concrete springs, and other incidental construction work have subsided to a certain extent, allowing the user to concentrate on electrical work. there were.

For example, work on control cables that connect electrical devices requires work to connect core wires and extend control cables, which generally ranges from several hundred to tens of thousands of core wires, and can reach up to tens of thousands if the work becomes huge. When the work is completed at a rate of several tens of minutes per day, due to the workability of the work, the work may be carried out with the entrance/exit of the control panel or the front door open for several days to several weeks. Ta. In this case, in the past, it was possible to protect the device from the environment by simply hanging a sheet, since there was relatively little falling dust.

However, the wave of modernization has changed building construction methods, and the construction period has been dramatically shortened.In the basement floors of buildings, only the loading entrance is open, and packing equipment and equipment can be moved. Bring it in! The site has been closed down and moved to a concrete-cast Tamagushi site on the ground floor.

In this construction method, the filling equipment and equipment installed in the basement are brought in at the same time, and the installation and construction work is done almost simultaneously. For this reason, the installation of electrical equipment must be carried out at the same time as construction work, control cable laying, and tethering work, and construction work must be carried out at the same time as hanging work, indoor air conditioning work, and machinery installation, as well as construction work. In Tonanashi, control cable installation and connection work will be carried out under conditions incomparably worse than in the past. The control panel also has the drawback of having to be protected from shortening of its lifespan due to the intrusion of dust and moisture.

Figures 1 and 2 show cross sections of conventional control panels, which include 19 control panels 1, a control panel 2, and a relay panel 3.
is attached, and a ceiling plate 5 is stretched thereon, which is then installed on the base 4. Control cable pit 9
Raise it up and pull it into the control panel, and connect the control wiring terminal 7.
Connect to. The wiring 8 in the control panel has already been wired at the manufacturing factory. After the control panel was brought in, the control cable installation, lead-in, and terminal processing and connection work continued for a long time.

The present invention allows large electrical items to be brought in first in accordance with the local construction environment and construction plan, and preliminary construction work is carried out, divided into smaller pieces at the required time, and the main parts that can be brought in are brought in in an extremely short time. The installation is a construction work, and the purpose is to provide a corrosion protection control panel that is suitable for the construction environment and is easy to install.

The present invention will be described below based on an embodiment shown in the drawings. FIG. 3 shows a cross-sectional configuration in which the control cable is led in from the bottom, and the control panel housing 1 with the ceiling plate 56 attached and the control wiring terminals 7 attached is installed on the base 4. In this case, the base 12 is also fixed to the floor at the same time.

In this state, the installation and connection work of the control cable 6 from the control cable pit 9 is completed. We will observe the situation for a while, and when the surrounding construction environment has calmed down, we will clean the surrounding area and remove the control panel 2 and the rim frame 17a attached to it, and the relay panel 3 and the rim frame attached to it. Prepare for the delivery of 17b. When the preparations are complete, the main parts of the control panel 2 - the body frame 17a and the relay nozzle 3 - the body frame 17b are carried in, installed on the bases 4 and 12, and then the control panel casing 1 is installed. All you have to do is connect the connection wiring 13, which was wired at the factory, and then reconnect the connection wiring 13, which was removed on one side, to the original connection.

In addition, in Fig. 3, 10 is a boss for preventing damage during transportation, l.
la is a terminal block 11 that relays internal wiring in the control panel 2;
b is a terminal block that relays the internal wiring of the relay panel.

In modern building construction methods, when transporting large equipment and equipment to the basement or ground floor, a large-diameter transport tool is used to transport a large amount of necessary items at once. In order to accommodate the construction process, a large, elegantly constructed electrical appliance was to be housed in an extremely poor construction environment that had not yet been completed. The reason given by the architect was that it would be difficult to bring in large items after No-Tsuchi had closed.

The present invention divides the main parts that cannot withstand the construction environment into smaller pieces and staggers the delivery, so that the installation environment can be stabilized, or at least after the installation and connection of control cables, which require a long construction period, have been completed. The idea was to focus on the fact that once the equipment is delivered, the installation and subsequent curing are not only sufficient, but also (5) there is no need to expose it to the harsh construction environment.

This construction method will be further explained with reference to FIGS. 4 to 6.

Figure 4 shows the postponed base 4 and base 12.

The figure shows the state in which the control panel casing 1 is carried in to a place where it is installed on the floor, and the control cable 6 is connected to the control wiring terminal 7.Then the control panel 2 is simply hung on a sheet.
- Arming frame 17a and relay panel 3 - Waiting for the arming frame 17b to be delivered.

In the past, the concept was that the control panel housing 1 and the control panel 2 and the relay panel 3 were inseparable during transportation, delivery, and installation, but this did not mean that electrical components, which are becoming more and more electronic components, would have a limited lifespan. Since we cannot save by shortening the time, we will delay bringing in the control panel 2 and the relay panel 3 until we have a prospect of achieving an acceptable condition through curing, although this will improve the environment.

In order to make this possible from a construction standpoint, the present invention attaches the control panel 2 and the relay panel 3 to the control panel 2 and the relay panel 3 with the frame frames 17a and 17b, respectively, so that all the control supplies are inside the control panel 2, the relay panel 3, and the frame frames 17a1 and 17b. 6 (6).

FIGS. 5 and 6 show a method of transporting and carrying in the control panel 2--flank frame 17a and the relay panel 3--flank frame 17b. In short, the control panel 2 - body frame 17a and the relay panel 3 - body frame 17b are loaded on the transport frame 15, sealed with the transport lid 14, fixed with the boss 10 while remaining stable, and transported all at once. transport. When unloading, all that is needed is to move it to the nearest location using the casters 16, and then manually load the respective control panel-frame frame 17a and relay panel 3-frame frame 17b, and remove the lid 14. and assemble as shown in Figure 3.

The relay panel 3 may remain in the conventional structure, and the body rim 17
By combining with b, the objective can be achieved. This allows the installation work to be completed as a control panel in an environment where quality can be guaranteed.

In the above embodiment, a case has been described in which the control cable 6 is drawn in from the bottom of the housing, but the same applies to a case in which the control cable 6 is drawn in from above.

As described above, according to the present invention, it is possible to provide an effective anti-corrosion control panel that facilitates installation work and prevents corrosion of control equipment from the presence of a poor atmosphere.
