Abstract

PURPOSE:To reduce current to be induced in iron braces and frame thus suppressing heating or to suppress heating due to the current itself by connecting tanks and bases, which are not connected electrically on the ground, through good conductor members. CONSTITUTION:A large current is induced in iron rods at such positions on the ground where there is no tank nor bases 7a-7d for feeding induced current through the bases 8a-8d. For example, a large current flows through the lower section of a current transformer tank 3 where current flow between circuit breaker tanks 2a, 2b and other tanks is blocked. Good conductor members, i.e. copper bars 12a, 12b, are connected such positions between the bases 7b, 7c or 8b, 8c in the proximity of the ground face. By such arrangement, induced current can be prevented from flowing into the frame and braces, and excessive heat generation due to the flowing of the current thereinto can be also prevented.

These are arranged in a π-shape as shown in Figure 7 or Figure 8. Furthermore, as shown in Figures 8 and 9, these tanks are provided with frames (7a), (7b), (7c), and (7d) that are integrally installed with the tank and support the tank. , the base supporting and fixing the frames (7a) to (7d)
bases (8a) to (8d) are provided, and this base (8a) to (8d) is provided.

A) to (7d) are grounded by a grounding wire (11). In the configuration of such a conventional device, the magnetic coupling between the bus bar and the tank is strong, and a large leakage magnetic flux due to the bus bar current causes induced currents, iu, iv, i, as shown in FIG.
wt flows. This induced current is when the bus current flows from the bushing (5a) to the bushing (5b), and the dotted line shows the induced current flowing through the reinforcement (9) installed on the ground. When an induced current flows in the tank, the cross-sectional area of the tank is large, so as the temperature of the tank rises, no loss occurs, but it is necessary to connect the disconnector and the circuit breaker between the disconnector tank (2). There is no tank for the induced current to flow between the current transformer tank (3) section or between the bushing tank (1) and the other phase, so this induced current flows through the base (8a
) to (8d) and flows to reinforcement (9).

[Problems to be Solved by the Invention] As described above, in the conventional device, an induced current flows, but especially in the disconnector tank (2) where the tanks are close to each other.
In between, more induced current flows through the reinforcement (9) nearer than the grounding wire (11), and therefore the induced current per each reinforcement (9) increases, causing the temperature of the reinforcement to rise. However, this temperature rise caused the problem that cracks were generated in the concrete (10).In addition, the induced current was caused by the pedestal (7b) on the way to the reinforcement (9).
) (7c), since a large amount of induced current flows through the pedestals (7b) (7c), the temperature of the pedestals (7b) (7c) rises, which poses a safety problem. The conventional device is
The objective was to solve these problems of crack occurrence and safety. This invention was made to solve the above-mentioned problems, and its purpose is to reduce heat generation by reducing the induced current flowing through the reinforcing bars or the frame, or to reduce the heat generation itself due to the flowing current. This is what we mean. [Means for Solving the Problems] The first aspect of the gas-insulated electrical device according to the present invention is to connect tanks or bases that are not electrically connected on the ground using a highly conductive material member. In the second invention, a mount cylinder of a disconnector tank,
Or, the bases of adjacent disconnector tanks in the same phase are connected by a highly conductive material member in an elliptical manner,
In the third invention, there is provided a pedestal made of shaped steel between the tank and the base, and when the pedestal is not electrically connected on the ground, a highly conductive material member is provided on the vertical part of the pedestal. are provided in parallel in close proximity to each other to shunt the induced current, and the fourth invention is directed to at least the vertical portion of the pedestal that is not electrically connected on the ground, or the reinforcement between the bases of a similar heath. It is made of stainless steel, which is a highly conductive material.

[Function] Since the present invention is ovalized as described above, in the first and second inventions, the tanks, the bases, or the pedestal cylinders are connected by a highly conductive material member. The induced current almost never flows into the reinforcing bars, but instead flows into the highly conductive material members, and does not cause large heat generation in the reinforcing bars. Since the electrically conductive material members are provided in parallel in close proximity, the induced current is shunted to the electrically conductive material members and the temperature of the pedestal does not rise. Since stainless steel is used in certain parts of the striations, the electrical resistance is low and therefore heat generation is kept low. [Example] The present invention will be described below based on the illustrated example. 1st rI! 1 shows an embodiment of the first invention. Reinforcement (9
) where a large amount of induced current flows is on the ground and where there are no tanks or mounts <7a> to (7d) that can cause induced current to flow between the bases (8a) to (8d). For example,
In Figure 1, this is between the disconnector tank (2aH2b) and the lower part of the current transformer tank (3) that prevents current from flowing between it and other tanks. A certain copper bar (12aH12b) is mounted on a stand (7b) (7e)
It is connected near the ground between the bases (8b) and (8c). By connecting the copper bars (12a) and (12b) in this way, the impedance is smaller compared to iron reinforcement (9), and the copper bar (12aH) has a larger current capacity.
Most of the induced current flows through 12b), and the induced current flowing through reinforcement (9) can be reduced. Also, copper bar (I
Za) (12b) is installed within 30en+ above the ground to ensure that it does not become an obstacle during equipment inspection. Next, FIG. 2 shows another embodiment of this first invention.

This is an example in which the connection is made using a copper bar (1.2&) (12b) made of paulownia, a highly conductive material provided in concrete 1 (10). By doing this, the copper bars (12a.) (1.2b) will move from the air to the concrete.
(10) Heat dissipation is greater when it is installed inside.
Therefore, temperature rise can be reduced and the copper bar (12a
) The fee for (12b) is also less. Next, an embodiment of the second invention is shown in FIG.

The disconnector tank (2aHZb) may be close to each other, and therefore a large amount of induced current may flow through the reinforcement (9). In such a case, the adjacent disconnector tank (2a
) (2b), the induced current concentrates on the opposing pedestals (7b) and (7c). Therefore, the frame (7b) (7c)
A copper bar (13), which is a highly conductive material member, is used to connect the pedestal tubes. When the pedestal tubes are connected by the copper cover (13) in this way, for the same reason as the first invention, the pedestal tubes (7bH7c
) flows through the copper cover (13) and the induced current decreases. Next, FIG. 4 shows another embodiment of this second invention. In this example, instead of the copper cover (13) in Fig. 3, the stand (7b) (7c) of the disconnector tank (2a) (2b) is used.
The bases on which the mounts (7b) and (7c) are installed are set as a common base (15) as a common unit, and the common base (15) is made of a highly conductive material and is provided to connect the frames (7b) and (7c).

In this case, the common base (15) is made of iron or the pedestal tube is made of stainless steel, and the common base (15) is made of iron with a large cross-sectional area.
Since the structure is constructed as follows, the induced current is at a common pace (15)
Therefore, the flow into the reinforcement is reduced.

In addition, it is not necessarily necessary to install the steel bars (16) in four parts as described above, but
H7c) should be installed close to the vertical part of the disconnector tank (2a) (2b), but if the space between the disconnector tanks (2a) and (2b) is narrow,
By installing the copper bar (16) in the recess of bH7c), the passage space for equipment inspection, etc. remains the same as before the installation of the copper bar (16), so inspections and other work remain unchanged. It's easy. Next, the fourth aspect of the present invention will be explained based on one embodiment thereof.
