Problems solved by technology

In addition, there are clock synchronization screens, AC and DC power supply screens, etc. These screen cabinets occupy a large area and have a high vertical distance. They were originally designed to carry secondary equipment, and did not consider the convenience of maintenance personnel to carry out work.
For example, when opening the front door of the screen cabinet, the freely movable cabinet door will cause inconvenience to the operation of the staff; secondly, when disconnecting the wiring on the top of the screen, the maintenance personnel with a shorter height must stand on tiptoe to operate, if at the same time Performing the transformation task of the multi-faceted screen is a challenge to its physical strength and endurance; moreover, when the protection device is increased and debugged, there is no special space on the screen for threading. If there are many test voltage and current circuits, it is difficult to sex plugged in

Abstract

The invention discloses a relay protection device secondary screen cabinet and a method. The relay protection device secondary screen cabinet comprises a cabinet body which is of a box-type structure; a first cabinet door is arranged on one side of the box-shaped structure, and a second cabinet door is arranged on the other side of the box-shaped structure; a windproof rod is arranged at the bottom of the box-shaped structure; a plurality of clamping grooves are formed in the bottom of the first cabinet door; the windproof rod can be clamped in different clamping grooves; a plurality of holes are formed in the bottom, close to the second cabinet door, of the interior of the box-shaped structure, so that cables can penetrate through the holes;and a folding step is arranged at the bottom, close to the second cabinet door, of the interior of the box-shaped structure.

Description

technical field [0001] The invention belongs to the technical field of screen cabinets, and in particular relates to a secondary screen cabinet of a relay protection device and a method thereof. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The secondary screen cabinet of the relay protection device is installed in the protection room of the substation to realize the carrying, centralized induction and protection of the protection device in the substation. There are many types of secondary screen cabinets, such as the main transformer protection screen cabinet - to place protection devices such as main transformer differential, backup on each side, and non-electric power; line protection screen cabinet - to place line protection devices of different voltage levels; public measurement and control Screen cabinet—a comprehensive device for remote s...
