Summary of the invention
The purpose of this invention is to provide a kind ofly while changing and safeguarding various instrument transformer, operate comparatively easy combined vacuum breaker device.
The technical scheme that realizes the object of the invention is: a kind of combined vacuum breaker device comprises casing, the operating mechanism that is provided with three vacuum tubes in casing and carries out the divide-shut brake action; Casing is provided with three inlet wire joint sleeves and three outlet joint sleeves, and casing also is provided with the electric bushing that connects be electrically connected to each inlet wire joint sleeve or outlet joint sleeve outward; The current enter of each vacuum tube and a corresponding inlet wire joint sleeve are electrically connected to, and the leading-out terminal of each vacuum tube and a corresponding outlet casing tube are electrically connected to.
In such scheme, described each inlet wire joint sleeve or outlet joint sleeve stretch out on the outer outboard end of casing, are arranged with current transformer for this phase current monitor to sampling use or for this phase voltage being monitored to the voltage transformer of the use of sampling.
In such scheme, also comprise zero sequence current mutual inductor or the zero sequential potential transformer on the outer outboard end of casing that stretch out that simultaneously is set in three inlet wire joint sleeves or three outlet joint sleeves.
In such scheme, describedly respectively connect on electric bushing the current transformer that is arranged with for this phase current being monitored to sampling use or for this phase voltage monitor to the voltage transformer of the use of sampling.
In such scheme, also comprise the zero sequence current mutual inductor or the zero sequential potential transformer that are set on three inlet wire joint sleeves or three outlet joint sleeves simultaneously.
The present invention arranges inlet wire joint sleeve and outlet joint sleeve on casing, and each inlet wire joint sleeve or outlet joint sleeve be electrically connected to connect electric bushing, in producing or using, can be required current transformer, voltage transformer or zero sequence current mutual inductor, being set in inlet wire joint sleeve or outlet joint sleeve stretches out on the outer outboard end of casing, due to connect electric bushing and each inlet wire joint sleeve or outlet joint sleeve be connected and disassembling section comparatively easy, when so the present invention has replacing and safeguards various instrument transformer, operate also comparatively simple and efficient advantage.
