Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas insulated switchgear that is easy to assemble.

[0002]

[Prior art]

 As shown in FIG. 3, the conventional gas-insulated switchgear has a busbar chamber opening 2, a disconnector chamber opening 3, a circuit breaker chamber opening 4, and a cable chamber opening in order from the top on the front surface of the main circuit housing gas container 1. 5 is formed. When assembling, a busbar is installed in the busbar room opening 2, a cable is installed in the cable room opening 5, a circuit breaker is installed in the circuit breaker room opening 4, and a disconnector is installed in the disconnector room opening 3. The main circuit of each part is connected from the hand hole.

[0003]

[Problems to be solved by the device]

 In the case of the conventional gas-insulated switchgear, all the main circuit parts are housed together in one container 1, so that each device is installed in a predetermined order from each opening 2, 3, 4, 5 into a container. It is difficult to carry out the work because it has to be attached to No. 1, and if some of the parts are not available, the work after that has to be interrupted, and the delivery time becomes long and delayed. The present invention has been made in view of the above points, and an object of the present invention is to provide a gas insulated switchgear that facilitates assembly work and shortens delivery time.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the gas insulated switchgear of the present invention comprises a plurality of divided containers such as a bus chamber container, a disconnector chamber container, a circuit breaker chamber container, and a cable chamber container. A flange is formed on the adjacent side of each container, and both of the adjacent flanges are airtightly joined to each other to form a hand hole in a part of the containers.

[0005]

[Action]

 In the gas-insulated switchgear of the present invention configured as described above, the main circuit housing gas container is divided into a plurality of units, and each unit is divided into a unit and a component. Can be installed, and the container with the equipment and parts attached can be completed by airtightly joining via the respective flanges, and the equipment and parts can be attached to each container in no order and the equipment and parts can be attached. Inventories can be stored for each selected container, inventory management is easy, and delivery times can be shortened.

【Example】

 An example will be described with reference to FIGS. 1 and 2. In these drawings, the same reference numerals as those in FIG. 3 indicate the same or corresponding ones, and the main circuit housing gas container 6 of the gas-insulated switchgear includes a busbar chamber container 7, a disconnector chamber container 8, a circuit breaker chamber container 9 and a cable. It is divided into a container chamber container 10, and each container 7, 8, 9, 10 is formed with a busbar chamber opening 2, a disconnector chamber opening 3, a circuit breaker chamber opening 4, and a cable chamber opening 5.

Then, a flange 11 is formed on the adjacent side of each container 7, a handhole is formed on the back surface of the disconnector chamber container 8 and the interrupter chamber container 9, and a lid 12 is provided for each of the adjacent containers. Flanges 11 are airtightly joined with the packing sandwiched therebetween.

Next, the assembly will be described. For each of the divided containers 7, 8, 9, and 10, the respective devices and parts are attached to the respective openings 2, 3, 4, and 5. That is, a busbar bushing 13 is provided in the opening 2 of the busbar chamber container 7, a disconnector 14 and an operating device 15 are provided in the opening 3 of the disconnector container 8, a gas circuit breaker 16 is provided in the opening 4 of the circuit breaker container 9, and a cable chamber container 10 is provided. The cable bushing 17 and the current transformer 18 are attached to the opening 5 of each.

Next, the containers 7, 8, 9 and 10 are airtightly joined to each other with the packing sandwiched between the respective flanges 11, and the equipments are joined from the handholes on the back of the containers 8 and 9 to the respective devices. After that, the handhole cover 12 is attached to complete the process.

[0010]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it has the following effects. In the gas-insulated switchgear of the present invention, the main circuit housing gas container 6 is divided into a plurality of units and is unitized, so that each of the divided containers 7, 8, 9, 10 is equipped with respective equipment and parts. It can be completed by airtightly joining the containers with the equipment and parts attached through the respective flanges 11, and there is no restriction on the order of attachment of the equipment and parts to each container 7, 8, 9, 10. It becomes possible to stock each container 7, 8, 9 and 10 in which the equipment and parts are mounted, the stock management is easy, and the delivery time can be shortened.
