Abstract

The invention relates to a transmission structure-based grounding switch comprising a disconnecting switch mounting support. A guide rail and a disconnecting switch pedestal are fixedly installed at the disconnecting switch mounting support. A transmission rod is movably connected with the disconnecting switch pedestal; and a grounding switch moving contact rod is sleeved at the transmission rod. A fixed hoop fixed at the grounding switch moving contact rod is movably connected with the disconnecting switch pedestal by a connecting plate and a support. A roller installed outside the grounding switch moving contact rod cooperates with the guide rail. A grounding switch static contact is fixed at a contact seat of a disconnecting switch. According to the invention, the pure rotation motion of the existing grounding switch is changed from one-step closing for being in place to two-step closing for being in place, thereby ensuring the contact reliability and the whole installation quality of the grounding switch. The capability of bearing of the dynamic stable current and the thermal stable current of the grounding switch can be improved; and a problem that the capacity of the existing grounding switch can not meet the requirement can be solved.

Description

technical field [0001] The invention relates to an outdoor high-voltage grounding switch, in particular to a transmission-structure grounding switch used in an outdoor high-voltage isolating switch. Background technique [0002] The outdoor high-voltage isolating switch is the most widely used high-voltage electrical appliance in the power system. It forms the main peripheral primary equipment of the substation with the outdoor high-voltage circuit breaker and the outdoor high-voltage grounding switch. The outdoor high-voltage grounding switch is used in conjunction with the outdoor high-voltage isolating switch. In most cases, it forms a combined electrical appliance with the outdoor high-voltage isolating switch. The support, porcelain bottle, and base of the high-voltage isolating switch are used. The outdoor high-voltage grounding switch is used when the power system is grounded, and it is used for reliable grounding of high-voltage busbars, circuit breakers and other el...
