Pluggable rapid installation high-voltage bushing

Abstract

The invention discloses a pluggable rapid installation high-voltage bushing, which comprises a high-voltage bushing and a base glass fiber reinforced plastic cylinder, wherein the high-voltage bushing comprises an upper sealing head, a hollow composite sleeve, a bushing flange and a capacitor core, the upper sealing head is arranged at the top part of the capacitor core, the bushing flange sleeves the middle section of a core body of the capacitor core, the hollow composite sleeve sleeves the capacitor core positioned between the upper sealing head and the sleeve flange, the capacitor core positioned below the sleeve flange is arranged inside the base glass fiber reinforced plastic cylinder, the top part of the base glass fiber reinforced plastic cylinder is connected with the bottom part of the sleeve flange through a base flange plate, a base bearing part is arranged at the bottom part of the base glass fiber reinforced plastic cylinder, and an oil compensator is further arranged on the middle flange body of the sleeve flange; and the oil compensator comprises a sleeve and an oil level display meter arranged at the tail end of the sleeve, and an oil pressure balance assembly is further arranged in the sleeve. The pluggable rapid installation high-voltage bushing is stable in structure, convenient to mount and dismount and capable of buffering the oil level and the oil pressure.

Description

technical field [0001] The invention relates to a pluggable and quickly installed high-voltage bushing, which belongs to the field of high-voltage bushings. Background technique [0002] With the development of society, electricity consumption is increasing rapidly, and the load of each substation is increasing. The stability of transformer high-voltage bushings has become the key to the stable operation of substations. The rod and the connecting rod of the base are usually connected by bolts alone, and there are phenomena that the bushing current-carrying guide rod and the base connecting rod are not concentric, the current-carrying guide rod is eccentric, the position is not correct, and it is easy to loosen; the thread between the base connecting rod and the base current-carrying plate connection, low current-carrying reliability, and poor connection stability. In addition, during assembly and disassembly, the above two methods are inconvenient to assemble and disassemble...

[0002] With the development of society, electricity consumption is increasing rapidly, and the load of each substation is increasing. The stability of transformer high-voltage bushings has become the key to the stable operation of substations. The rod and the connecting rod of the base are usually connected by bolts alone, and there are phenomena that the bushing current-carrying guide rod and the base connecting rod are not concentric, the current-carrying guide rod is eccentric, the position is not correct, and it is easy to loosen; the thread between the base connecting rod and the base current-carrying plate connection, low current-carrying reliability, and poor connection stability. In addition, during assembly and disassembly, the above two methods are inconvenient to assemble and disassemble; in addition, the existing transformer high-voltage bushing cannot protect the oil between the transformer bushing and the base. It is not possible to buffer the oil pressure between the transformer bushing and the base when the oil pressure changes due to weather changes
