Description

[Detailed Description of the Invention] This invention relates to an improvement of a capacitor facility in which various devices such as a capacitor are installed on a concrete base.

In the case of capacitor equipment that consists of a reactor and switchgear equipment installed on a concrete base along with the capacitor, each equipment needs to be installed on the same horizontal plane. That is, each device is connected by a conduit (oil duct) containing a conducting wire, and for this conduit connection, it is necessary to maintain the flange positions of the mutual devices at the same height with high precision. In the past, work was done to ensure that the concrete base surface was a uniform horizontal surface when pouring concrete;
Currently, it is difficult to create a uniform horizontal surface over a distance of 12 m.

In addition, in the case of the conventional structure in which the bottom of the device is placed directly on the concrete base, there is a risk that if rainwater enters the small gap and remains, rust will form on the bottom of the device.

This idea was devised in view of the above points, and allows for easy horizontal management during the installation of each device.
It also aims to provide capacitor equipment that is free from rust at the bottom of the equipment.

This idea is based on a concrete base with a mounting table for the equipment buried within it.The more detailed structure is that various equipment such as capacitors, reactors, and switchgears are installed on the concrete base and connected through conduits. In the capacitor equipment to be used, a mounting stand for each device made of molded rust is buried in the concrete base so that its top surface slightly protrudes from the surface of the concrete base and is positioned horizontally at the same height. This is a capacitor facility with various equipment installed.

Examples of this invention will be described in detail below with reference to the drawings, but this invention is not limited to the following examples.

FIG. 1 shows a planar configuration of a capacitor equipment 1 of this invention, and FIG. 2 similarly shows a side configuration. 2 is a concrete base, and six capacitors 3, one reactor 4, and a switchgear 5 are installed on the concrete base 2. A device mounting table 6 made of I-shaped steel is buried in the concrete base 2, and various devices are installed on this mounting table 6. The concrete base 2 is formed by positioning and fixing the above-mentioned mounting table 6 on the base or the like so that its upper surface is at the same height and horizontal, and pouring concrete in this state. The concrete is poured so that the surface of the concrete base 2 is slightly lower than the top surface of the mounting table 6, as shown in FIG. 3, that is, the top surface of the mounting table 6 slightly protrudes from the surface of the concrete base 2. The protrusion height h of the upper surface of the mounting table 6 from the two surfaces of the concrete base is 5 to 10 mm, and two mounting tables 6 are used parallel to the bottom surface of one device. Since a total of 8 devices are installed, a total of 16 mounting tables 6 are buried. When various devices are installed on the mounting table 6, the concrete base 2 on the top surface of the mounting table 6
A space 7 having a protruding height h from the surface is formed between the bottom surface 8 of the device and the two concrete bases. Various devices are installed on the mounting table 6 and the conduit 9
The connecting flanges of the pipes 9 and 9 face each other at exactly the same height and are attached to the respective pipes 9. To actually install the equipment, after placing the equipment in a predetermined position, anchor bolts 10 protruding from the two surfaces of the concrete base are inserted into fixing holes in the flange 11 of the equipment, and nuts 12 are tightened.

This idea is structured as described above, so
As long as the mounting table is buried at a predetermined height, equipment can be installed at a predetermined height regardless of the unevenness of the concrete base surface, and pipe connections can be made without any problems. Burying the mounting table at a predetermined height is technically much easier than keeping the entire surface of the conventional concrete base horizontal.

In addition, by providing a mounting table, a space of a certain width is created between the bottom of the device and the concrete base surface, which improves ventilation in that area and keeps it dry, which prevents rust from forming on the bottom of the device. You no longer have to worry about it.
