Description

Technical Field

[0001] The utility model relates to the technical field of residual voltage busbars, in particular to a low residual voltage busbar protection cabinet. Background Art

[0002] Low residual voltage busbar is a commonly used method in power systems. At present, the protection cabinet used for low residual voltage busbar has a low bottom thickness. When used for a long time, the low residual voltage busbar inside the cabinet will be damp due to erosion by ground liquid and moisture, which will affect its service life.

[0003] After searching, a low residual voltage busbar protection cabinet disclosed in the prior art (application number: CN202223267023.8) records in the text that "a pad is fixedly installed on the bottom of the cabinet, and a partition is arranged at intervals in the inner cavity of the cabinet, and the partition is a perforated plate, and the inner cavity of the cabinet is symmetrically provided with triangular plates, and the triangular plates are located at the bottom of the cabinet, and the internal array of the triangular plates is provided with a fan, and the fan passes through the side wall of the triangular plate and extends to the outside thereof."; The protection cabinet can raise the cabinet by means of the pad and the drain port, and can divert the liquid accumulated on the outside of the pad to prevent it from accumulating on the outside of the device for a long time; and the triangular plate and the fan arranged in its internal array can play a role in the inside of the cabinet. The cabinet has a cooling effect to avoid a large amount of heat accumulation inside the cabinet, and the air groove, air holes and dustproof plates can connect the inside of the cabinet with the outside world, thereby maintaining the effect of internal air circulation of the cabinet. However, the dustproof plates and arc plates set in the protection cabinet can only prevent naturally falling dust and debris. For those dust and debris that can float synchronously with the airflow, the dustproof effect of the dustproof plates and arc plates is poor. At the same time, the exhaust holes of the protection cabinet are set on the upper surface of the cabinet, and then the external airflow will flow into the cabinet from both sides of the cabinet, and then the gas with increased humidity near the ground will also flow into the cabinet, thereby increasing the humidity inside the cabinet, making the low residual voltage bus prone to moisture problems, affecting the service life of the low residual voltage bus.
