Problems solved by technology

However, during the installation process, the gas in the taper sleeve cavity of the electrical equipment cannot be discharged, and the sealing plug is difficult to install in place; in addition, during the normal operation of the equipment, when the internal electric field changes, the sealing plug and the inner Intermittent discharge will occur between the conductors of the tapered sleeve. If the arc gas generated cannot be effectively discharged, it will accumulate for a long time. When a certain pressure limit is reached, the sealing plug will pop out under the pressure, posing a threat to the safety of equipment operation.
The above problems have existed for a long time, posing a serious threat to equipment and personal safety, and have not been resolved until now

Abstract

The invention relates to an insulation sealing plug which comprises a main insulator (1) and a top sealing flange (2), wherein the top sealing flange (2) is arranged at one end of the main insulator (1), wherein a bottom sealing flange (3) is arranged at the other end of the main insulator (1); an air discharge device is arranged inside the main insulator (1); and the air discharge device is embedded inside the main insulator (1). Therefore, the insulation sealing plug has the advantages that an air discharge pipeline is wound inside an insulation material, under the condition that normal insulation condition is ensured, the air generated inside electric equipment is discharged at any time so as to ensure the stable pressure inside the equipment; the plug sealing flange and the insulation material are integrally made; the mechanical structure is reliable in strength; the electric field intensity is uniform; and meanwhile, external inserted type electric equipment can be configured, so that the insulation sealing plug is convenient to install and maintain.

Description

technical field [0001] The invention relates to an insulating and sealing plug, in particular to an insulating and sealing plug. Background technique [0002] Usually, when the inner cone bushing of electrical equipment is not connected temporarily, it is necessary to install a sealing plug to ensure the insulation of the product. However, during the installation process, the gas in the taper sleeve cavity of the electrical equipment cannot be discharged, and the sealing plug is difficult to install in place; in addition, during the normal operation of the equipment, when the internal electric field changes, the sealing plug and the inner Intermittent discharge will occur between the conductors of the tapered sleeve. If the generated arc gas is not effectively discharged, it will accumulate for a long time. When a certain pressure limit is reached, the sealing plug will pop out under pressure, posing a threat to the safety of equipment operation. The above problems have exi...
