Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a liquid resistor which is designed to facilitate maintenance and inspection by identifying an insulating cylinder inside the tank and to minimize the amount of damage caused by maintenance and inspection. This is about the improvement of.

[Technical background of the invention]

FIG. 1 shows a schematic configuration of a liquid resistor of medium capacity or higher.

That is, in a tank 2 containing an electrolytic solution `rIL1, a ta3, a cylindrical tank 4, and a cylindrical tank 4 are arranged facing each other, and are insulated from each other by an insulating tube 5. The fixed electrode 3 is fixed to the main circuit terminal 8 via a fixed electrode rod 7 formed by an insulated vibro. ! The insulating tube 5 is fixed to the partition 10 via a mounting rod 9, and the insulating tube 5 is stored inside the tank 2 in a suspended state from above.
The movable electrode 4 is supported by a common frame 12 by a movable electrode rod 11 passing through the partition plate 10, and is star-connected with the common frame 12. And common frame 12 is chain 1
3, which is connected to the drive unit 14 via the insulating cylinder 5. Since such a liquid resistor with a content of less than (% in height direction) is small and light f
I can do it. Therefore, even with a structure in which the insulating tube 5 is suspended from above, it is not necessary to take out the insulating tube 5 together with the electrode part to the outside of the tank 2 during maintenance and inspection. This will not cause any hindrance to the work of removing the insulation cylinders for scrap inspection.

However, in a liquid resistor of this size, it is necessary to have a long electrode stroke, a large electrode shape, and furthermore, it is necessary to make the liquid resistor simple. For this reason, the shape of the insulating cylinder is thicker, and the power of the cylinder is also increased. Therefore, if there are restrictions on lifting capacity due to the structure of the building during maintenance and inspection, it will not only be extremely difficult to take out the insulating tube to the outside of the tank, but it will also be extremely difficult! When inspecting the poles, it takes a long time to attach and detach the insulating cylinder. In addition, there is a risk that the insulating tube may be shaken due to vibrations during transportation, causing damage to the insulation. Similarly, in order to discharge the heat energy generated between the current-carrying center poles to the outside of the upper layer, forced convection is performed by a pump.The insulating cylinder is shaken by the influence of water pressure and comes into contact with the electrodes, which completely restrains the movement of the magnetic poles. Oh (-regameta.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid resistor that improves the method of supporting an insulating tube, facilitates maintenance and inspection, and improves the reliability of the electrode section.

[Overview of the Invention] The present invention has a structure in which a support member for an insulating cylinder is fixed in a tank, and the insulating cylinder is fixedly supported mainly by this support portion.

[Embodiments of the invention]

FIG. 2 shows the main structure of the first embodiment of the present invention.

Note that the same parts as in FIG. 1 are denoted by the same reference numerals, and the parts not shown are the same as in FIG. 1.

The liquid resistor of this example has an electrolyte 1 as shown in FIG.
A support member 2 that supports an insulating cylinder 5 in a tank 2 containing a
1 is constructed and fixed parallel to the bottom plate of the tank 2 and along the arrangement direction of the grade 1 strips 5, corresponding to the top, bottom, left and right 41 fixed points of each insulating tube 5. Note that the supporting members 21 disposed on the left and right sides, particularly on the upper left and right sides, are disposed at intervals of at least the outer diameter in the insulation direction 5. - In case of force failure I#, simple 5, the support member 21 is placed on the support member 2 and rotated in a predetermined manner.
A removable mounting seat 22 is provided at the top end, which can be removed by avoiding the process. These mounting seats 22 are each fixed to the support member 2J by a fixed rod 23. Furthermore, a pipe 24 for discharging the electrolyte 1 cooled inside the insulating cylinder 5 to the outside is provided in the paper part of the tank 2. It is being

With such a configuration, the II electrode section insulating cylinder 5tX can be extracted f1. In order to maintain and inspect the electrode part inside the tank, the height of the building where the liquid resistor is installed must be lowered, and a special construction is required to temporarily suspend the electrode part outside the tank. No work is required for assembling the pedestal and installing the electrode section. In addition, it is possible to completely prevent the lozenge rim tube 5 from shaking due to vibrations during transportation and the influence of water pressure due to forced convection, thereby improving the reliability of the electrode section. In addition, support thin profit 21 and tank 2
It also has the advantage of being able to mechanically overpower.

In addition, in the above embodiment, the force required to place the insulation m5 on the upper and lower support members 21 is as small as possible as long as the above-mentioned effects can be obtained, and it is better to place the support member 21 in one place. . A second embodiment of the present invention that takes these points into consideration is shown in FIG. 3, where the same parts as in FIG.

In FIG. 3, the mounting seat 2 of the support member 2 and the insulating cylinder 5 is shown.

Such deviations can be avoided at the initial assembly stage to facilitate centering adjustment between the insulating cylinder 58b and the electrode part outside the tank 2, and to avoid damage to the electrode part during maintenance and inspection. 5) When removing or inserting the
, '(When J is used as a guide, the electrode part and the insulating tube 5 do not come into contact with each other, so there is only one force. Therefore, the centering accuracy can be improved during insertion, so there is no need to re-align the center.)

A third embodiment of the present invention, as shown in FIG.
The arrangement of the supporting members 2 fixed therein is substantially the same as in the first and second embodiments, and corresponds to one location on both sides of the substantially central portion of the insulating cylinder 5. The mounting seat 41 provided on the insulating cylinder 5 is fixed to the support member 21 at the bottom surface.
The insulating cylinder 5 is vertically supported by the support part 21VCPe.

In addition, in the fourth embodiment of the present invention, as shown in FIG. The structure is such that a mounting seat 52 is provided which is placed on the support member 5.

According to this fourth embodiment, since the mounting of the support member 5'1 can determine the shape of the mounting seat 52 without being restricted by interlocking, the installation of the absolute F# tube 5 is stable. You can improve. Further, since the mounting pitch can be made the same both in the front and rear directions and in the left and right directions as shown in the figure, the mounting direction of the insulating tube 5 is not restricted.

This ice investigation can be modified as much as desired without changing its gist.

〔Effect of the invention〕

According to the present invention, the supporting member of the cylinder is firmly attached to the V-break inside the tank, and this supporting member fixes and supports the insulating cylinder by itself, so that the height of lifting the liquid resistor during maintenance and inspection can be reduced. By lowering the value, the workability and f'LM efficiency are improved. In addition, the reliability of the insulating glass against various vibrations is also improved.

In addition, the inside of the tank can be reinforced, making it lighter overall.
