AI Technical Summary

Technical Problem

The existing isolating switch insulation sheath has problems such as easy leakage at the joint gap, easy rust of bolts, and poor heat dissipation, which affects the service life and safety of the equipment.

Method used

An insulating sheath is designed, which includes a sheath body, an outer shell, an extension box and a vent tube. Gas exchange and heat dissipation are achieved through the vent tube. The sheath is equipped with a water collection device to automatically clean the vent tube to prevent blockage. The outer shell is detachable to block dust and rainwater, and the water collection device collects rainwater for cleaning the vent tube.

Benefits of technology

It effectively prevents dust and rain from entering, ensures insulation performance, improves equipment reliability and service life, maintains a suitable equipment temperature through a dual heat dissipation mechanism, reduces aging risks, and simplifies maintenance processes.

Abstract

The invention discloses a disconnecting switch insulating sheath, and relates to the technical field of insulating sheaths, the disconnecting switch insulating sheath comprises a sheath body, one side of the sheath body is provided with a through groove, the through groove is matched with a disconnecting switch, one side, close to the through groove, of the sheath body is detachably connected with a shell, and the shell is used for preventing dust and rainwater from entering the sheath body from the through groove. Extension boxes symmetrically communicate with the side, away from the shell, of the sheath body, a plurality of through holes are formed in the sides, away from the sheath body, of the extension boxes, vent pipes are fixedly installed at the through holes, and water collecting devices are arranged on the extension boxes and used for cleaning the vent pipes. According to the invention, the through groove is matched with the isolation switch, so that the protection sleeve body is tightly attached to equipment, and the reliability of insulation protection is improved; the extension box is combined with the vent pipe, internal hot air can be discharged through the vent pipe, the vent pipe can be cleaned through the water collecting device, blocking is prevented, and the ventilation function is kept effective for a long time.
