Abstract

(57) [Summary] [Purpose] The installation area can be reduced even if several drawer type circuit breakers are installed. [Structure] Draw-out circuit breakers 5a, 5b, 5c are built in the box body 6 in the up-down direction and the left-right direction respectively, and the cable heads 7a, 7b, 7c and the branch main bus 2 are arranged on the back side of the box body 6. , The draw-out circuit breakers 5a, 5b, 5c and the upper disconnector 3
a, 3b, 3c, and lower disconnecting sections 4a, 4b, 4c, and the main busbar 1 is arranged on the side surface of the box body 6 in a direction perpendicular to the moving direction of the draw-out circuit breakers 5a, 5b, 5c, Connect to the branch main bus 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a solid insulation switchgear in which a high voltage charging section is covered with a solid insulation.

[0002]

[Prior art]

 FIG. 2 shows an example of a conventional solid insulated switchgear, in which a box body 6 has one drawer type circuit breaker 5 built in, and a cable head 7 and a main bus bar 1 are provided on the back side of the box body 6. Each of them is arranged and connected to the draw-out circuit breaker 5 by an upper disconnecting section 3 and a lower disconnecting section 4.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional method, when a large number of draw-out circuit breakers are required, the main bus bar is connected in the horizontal direction, so that the installation area increases by the number of draw-out circuit breakers. Therefore, the present invention can arrange a large number of drawer type circuit breakers in a small installation area.

[0004]

[Means for Solving the Problems]

 In the present invention, several drawer type circuit breakers are housed vertically and horizontally, and a branch main busbar is formed in the box body in a direction perpendicular to the moving direction of the drawer type circuit breaker. A disconnecting portion, which is disposed on the rear surface and is connected to the branch main bus and is connected to and separated from the draw-out circuit breaker, is provided between the branch main bus and the draw-out circuit breaker, and a cable head is further provided at the draw-out circuit. A disconnection section, which is disposed on the back surface of the box in the moving direction of the breaker and is connected to the cable head and separates from the draw-out breaker, is provided between the cable head and the draw-out breaker. On the other hand, a main busbar is arranged on a side surface inside the box body in a direction perpendicular to the moving direction of the draw-out circuit breaker, and is connected in a direction perpendicular to the branch main busbar.

[0005]

[Action]

 By configuring as described above, the conventional draw-out type circuit breaker can be installed in a small number of installation areas, and a large number of draw-out type circuit breakers can be mounted, and the installation area can be reduced.

[0006]

【Example】

 FIG. 1 shows an example of the solid insulated switchgear of the present invention. The box body 6 has pull-out circuit breakers 5a, 5b, 5c built in vertically and horizontally, respectively. Cable heads 7a, 7b, 7c and a branch main bus 2 are respectively arranged. With respect to the draw-out circuit breakers 5a, 5b, 5c, upper disconnecting portions 3a, 3b, 3c, lower disconnecting portions 4a, 4b, 4c are arranged. Further, on the side surface of the box body 6, there is a main bus bar 1 arranged at a right angle to the branch main bus bar 2 in the vertical direction of the box body 6 and connected to the branch main bus bar 2. By arranging as described above, several drawer type circuit breakers can be arranged vertically and horizontally.

[0007]

[Effect of device]

 According to the present invention, since several drawer type circuit breakers can be connected vertically and horizontally, the installation area can be reduced and the solid insulated switchgear can be applied to a place with a smaller installation space. Become.

Claims (1)

[Scope of utility model registration request] 1. A plurality of drawer type circuit breakers are housed vertically and horizontally in a box body, and a branch main busbar is formed on the back surface of the box body in a direction perpendicular to the moving direction of the drawer type circuit breaker. A disconnecting portion is provided between the branch main bus and the draw-out circuit breaker, which is connected to the branch main bus and comes in contact with and separates from the draw-out breaker, and a cable head is further provided at the draw-out breaker. A disconnecting portion which is disposed on the back surface of the box in the moving direction of the container and which is connected to the cable head and contacts and separates the draw-out type circuit breaker is arranged between the cable head and the draw-out type circuit breaker. On the other hand, a solid insulated switchgear in which a main busbar is arranged on a side surface inside the box in a direction perpendicular to a moving direction of the draw-out circuit breaker and is connected in a direction perpendicular to the branch main busbar.
