Abstract

PROBLEM TO BE SOLVED: To facilitate the installation work of a gas breaker body, by installing the foot of the gas breaker body and the existing foundation through an adaptor base by a holein anchor bolt. SOLUTION: A hole-in anchor bolt 5 is laid in an existing foundation 2, and an adaptor base 3 is fixed by a nut 6. This adaptor base 3 is made in the dimension corresponding to the required area of the foot 4 of a gas breaker body 1. Then, the foot 4 of the gas breaker body 1 and the existing foundation 2 are installed through the adaptor base 3 by a hole-in anchor bolt 5. Hereby, the work using a track crane and the assembly work on the existing foundation 2 can be omitted, and the replacement work on the site of the gas breaker 1 in shortened period becomes possible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas circuit breaker installation apparatus for installing a gas circuit breaker body on site.

[0002]

2. Description of the Related Art Generally, a gas circuit breaker body is installed on a foundation via an adapter base, and when replacing an existing gas circuit breaker body with a new gas circuit breaker body,
It is installed on its existing foundation via an adapter. At the time of the replacement work of the gas circuit breaker body, the line of the system to which the gas circuit breaker body is connected is stopped. In this case, it is necessary to perform the operation in the shortest period so that the stoppage of the line does not greatly affect the power transmission supply.

FIG. 2 is an explanatory view of the installation of the gas circuit breaker main body 1. The gas circuit breaker main body 1 is mounted on the existing foundation 2 via the adapter base 3, but conventionally, the existing gas circuit breaker main body 1 is first removed, and after the removal, the adapter base 3 is assembled on the existing foundation 2. , And the gas circuit breaker main body 1 is installed and fixed thereon. in this case,
The adapter base 3 is assembled using a crane truck. As described above, the gas circuit breaker main body 1 is fixedly installed after the adapter base 3 is assembled on the existing foundation 2 by the crane truck.

[0004]

However, the adapter base 3 is divided and carried in due to transportation restrictions, and it is necessary to assemble it on the existing foundation 2 by a crane truck. It takes. If it takes time for installation work, the line will be stopped during the work period, which may hinder transmission power.

An object of the present invention is to provide a gas circuit breaker installation apparatus which can easily perform a work of installing a gas circuit breaker main body and can shorten a construction period.

[0006]

A gas circuit breaker installation apparatus according to the present invention is a gas circuit breaker installation apparatus in which a gas circuit breaker main body is installed on an existing foundation via an adapter base. The installation area of the legs of the gas circuit breaker main body is set to be large, and the legs and the existing foundation of the gas circuit breaker main body are installed with hole-in anchor bolts via the adapter base.

In the installation apparatus for a gas circuit breaker according to the present invention, an adapter base having the same size as the leg of the gas circuit breaker main body is attached to the existing foundation with a hole-in anchor bolt, and the gas circuit breaker main body is mounted above the adapter base. Install the legs.

[0008]

Embodiments of the present invention will be described below. FIG. 1 is an explanatory diagram of an embodiment of the present invention. In the first embodiment, the adapter base 3 has the size of the installation area of the leg 4 of the gas circuit breaker main body 1, and the leg 4 of the gas circuit breaker main body 1 and the existing foundation 2 are connected via the adapter base 3. Are installed by hole-in anchor bolts 5.

In FIG. 1, a hole-in anchor bolt 5 is cast on an existing foundation 2, and an adapter base 3 is fixed with a nut 6. The adapter base 3 has a size corresponding to the required area of the leg 4 of the gas circuit breaker main body 1. Therefore, the adapter base 3 has a weight that can be carried by human power and is carried in an assembled state. Thereby, the work using the crane truck and the existing foundation 2
Can be omitted. Due to the structure of the adapter base 3, the on-site replacement work of the gas circuit breaker main body 1 can be performed in a shorter period than in the conventional technique without using a crane truck.

[0010]

As described above, according to the present invention, when replacing the gas circuit breaker body using the existing foundation, the adapter base can be installed without requiring a crane truck. That is, it is possible to reduce the carrying-in installation work related to the adapter base used at the time of the installation work of the gas circuit breaker main body, so that the installation work of the gas circuit breaker can be shortened.
