Embodiment Construction

[0014] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0015] A compact and safe switching station, including a cement shell 1, a switchgear PT interval, a switchgear outgoing line interval and a manhole 8, and the above-mentioned switchgear PT interval, switchgear outgoing line interval and manhole are all set in the cement shell . A bracket 7 is installed in the cement shell above the manhole. The bracket is composed of a top plate and outriggers. The top plate is installed on the outriggers, and the outriggers are installed on the bottom plate of the cement shell. A cable channel is formed, and a load switch cabinet 6 is installed above the top plate. The upper port of the load switch cabinet is connected to the outlet interval through the cable through the cable...

Abstract

The invention relates to a compact safety switching station, which includes a cement shell, a switch cabinet PT interval, a switch cabinet outlet interval and a manhole, and a mounting frame is installed on the upper part of the cement shell, and the station PT is installed on the mounting frame Inside, a baffle is set on the outside of the station PT, the baffle is connected with the vertical beam of the installation frame through bolts, and one or more inspection windows are embedded on the baffle. The present invention is a compact and safe opening and closing station with ingenious and reasonable design, simple structural improvement, improved construction efficiency and reduced construction cost. The present invention adds a baffle at the front end of the PT, which improves the safety of equipment operation and ensures the user's safety.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a compact and safe switching station. Background technique [0002] The arrangement of ordinary switching stations is the PT interval of the switch cabinet, the outlet interval of the switch cabinet and the manhole. The combination of these three and installed in the cement shell becomes the switching station. The main busbar of the PT cabinet and the main busbar of the switch outlet interval are connected to each other to make it work. The existing equipment does not have a PT cabinet, and there is only one reserved manhole. In the project of automatic transformation of the opening and closing station, due to the site terrain, the foundation cannot be expanded, but at this time the user needs to retain the manhole, increase the PT, and for convenience For maintenance, it is also necessary to install a load switch at the front end of the PT, which increases the diffic...
