Abstract
The utility model relates to an extra-high voltage alternating current circuit breaker, comprising a shell, arc extinguishing chambers, an insulating support, an insulating tension pole and an insulator. The extra-high voltage alternating current circuit breaker is characterized in that the arc extinguishing chambers inside the shell are connected in series, a fracture voltage-sharing capacitor and a voltage-sharing shielding cover are arranged in the shell, a pressure release device is arranged at one end of the shell, the arc extinguishing chambers and the shell are arranged coaxially, as four arc extinguishing chambers in the shell are connected in series, and the fracture voltage-sharing capacitor and the voltage-sharing shielding cover are arranged in the shell and the pressure release device is arranged at one end of the shell, the insulating level and breaking capacity of a product are improved, each fracture bears the same voltage at the tripping position, and the extra-high voltage alternating current circuit breaker is suitable for a 750kv-1000kv electric system.
Description
Technical field
The utility model relates to the AC circuit breaker technical field, particularly a kind of extra-high-voltage alternating current circuit breaker that is applicable to the 750kV-1000kV electric power system.
Background technology
The high-voltage alternating sulfur hexafluoride breaker is to be used for the visual plant of switching regular link or faulty line in the electric power system, insulation level and connecting-disconnecting function that two present fracture high-voltage alternating sulphur hexafluorides open circuit are difficult to satisfy the requirement of 750kV-1000kV electric power system to the high-voltage AC breaker respective capabilities, exist insulation level and connecting-disconnecting function is poor, the voltage difference that each fracture bears in the separating brake position is easy to generate the shortcoming that the housing middle part sinks and can't realize pressure release.
Summary of the invention
The purpose of this utility model provides a kind of insulation level height, and the strong and dependable performance of connecting-disconnecting function is applicable to the extra-high-voltage alternating current circuit breaker of 750kV-1000kV electric power system.
The utility model is to realize like this, it comprises housing, arc control device, insulation support, insulated tension pole and insulator, the arc control device series connection that it is characterized in that being installed in the housing is provided with, in housing, be provided with the fracture equalizing capacitance and all press radome, end at housing is provided with pressure relief device, arc control device and the coaxial setting of housing.
The utility model is owing to be installed in the interior arc control device series connection setting of housing, in housing, be provided with the fracture equalizing capacitance and all press radome, end at housing is provided with pressure relief device, the insulation level and the connecting-disconnecting function of product have been improved, the identical voltage that each fracture is born in the separating brake position is suitable for the 750kV-1000kV electric power system and uses.
