Safe ring main unit

Abstract

The invention discloses a safe ring main unit which comprises a cabinet body and a cabinet door, wherein a hollow cavity is formed in the top of the cabinet body and is open on the front side surface and closed on the other surfaces, and a chute is formed in the bottom surface of an inner cavity of the hollow cavity; the top end of the cabinet door is connected with a pulley through a shaft, the pulley is glidingly connected with the chute in the bottom surface of the inner cavity, and an opening in the front side surface of the hollow cavity adopts a rectangular through hole; a protective cover is arranged at the top end of the front side surface of the hollow cavity; a handle is arranged on the outer side of the lower part of the cabinet door, and a bulge is arranged on the inner side and is movably clamped with a clamping hole in the cabinet body; a mounting plate is arranged in the cabinet body, and radiating holes are uniformly distributed in the upper end and the lower end of the mounting plate. The cabinet door adopts a folding pull type door, the cabinet door can be concealed in the hollow cavity in the upper part of the cabinet body after opened, space outside the cabinet body is saved, maintenance and operation of a worker are facilitated, the safe ring main unit is safe and convenient to use, and the cost is saved.

Description

technical field [0001] The invention relates to a ring network cabinet, in particular to a safety ring network cabinet. Background technique [0002] The ring network power distribution method is a safe and reliable urban power distribution method, which has been widely used in urban and rural power transmission networks, such as switch stations, unattended box-type substations, residential quarters, buildings and large and medium-sized enterprises. Under normal circumstances, for the construction unit, the power distribution planning and design work should be completed at one time. In actual construction, the improvement of power distribution cabinets is done in stages, and the method of gradually adding power distribution unit cabinets is used to complete. Therefore, the power distribution unit cabinets currently produced are generally reserved with expansion interfaces, so that users can easily expand the power supply capacity according to plans or actual development...

Problems solved by technology

With the development of the distribution network and the use of a large number of ring network cabinets, the workload of maintenance inspections and operations is increasing. It is necessary to open the cabinet door of the ring network cabinet. The traditional cabinet door adopts double-leaf split and multi-leaf horizontal push-pull In the actual work on site, the cabinet door of the ring network cabinet is affected by the operating time and the outdoor operating environment. Some cabinet doors are deformed or due to the influence of the basic factors of the cabinet, resulting in many cabinet doors that are difficult to open and close. The problem is becoming more and more prominent, and it also brings hidden dangers to safe production
