Problems solved by technology

[0002] At present, the cable holes at the bottom of the substation trolley cabinets are generally blocked with fireproof mud or lime. Since there is no support at the bottom of the holes, the fireproof mud in the holes has the defects of high temperature depression and sinking in summer, low temperature hardening, dry cracking and falling off in winter. Animals entering, combination switchgear moisture-proof, fire prevention and other aspects bring safety hazards. In recent years, line tripping and discharge phenomena caused by hole sealing defects in various substations have occurred from time to time
Moreover, a large amount of manpower and material resources are spent every year to seal the holes in the substation, resulting in a waste of resources and bringing dirt and inconvenience to the work site.

Abstract

The invention discloses a moveable cable cavern stopper, comprising a cable fireproof insulation sleeve (3), the periphery of the cable fireproof insulation sleeve is provided with a neck (12), the cable fireproof insulation sleeve (3) is connected with a fireproof insulation plate (2) opened with circular holes by the neck (12), and the two ends of the fireproof insulation plate (2) are respectively connected with a slideway (1). The invention is safe and reliable, is rapid to assembly, is firm and durable, does not deform or drop and has favourable fireproof and moistureproof functions.

Description

Technical field: [0001] The invention relates to a movable cable hole plugging device, which belongs to the technical field of power system substation operation and is applied to primary equipment areas such as cable interlayers and high-voltage chambers of power system substations. Background technique: [0002] At present, the cable holes at the bottom of the substation trolley cabinets are generally blocked with fireproof mud or lime. Since there is no support at the bottom of the holes, the fireproof mud in the holes has the defects of high temperature depression and sinking in summer, low temperature hardening, dry cracking and falling off in winter. Animals entering, combination switchgear moisture-proof, fire prevention and other aspects have brought safety hazards. In recent years, line tripping and discharge phenomena caused by hole sealing defects in various substations have occurred from time to time. Moreover, a large amount of manpower and material resources are...
