Abstract
The utility model relates to the technical field of high-voltage switch cabinets, and especially relates to a 10kV high-voltage switch cabinet grounding switch and cable chamber door interlocking mechanism. The 10kV high-voltage cabinet grounding switch and cable chamber door interlocking mechanism comprises a cabinet body and a cabinet door. Two symmetrical fixed supports are disposed on the inner wall of the cabinet body. A slide connecting rod penetrates through sliding holes of the two fixed supports. A knife disc rotation mechanism is mounted on a cabinet body control panel, and is connected with a grounding switch through a control lever to realize switching off and switching on. A main shaft of the grounding switch is sleeved by a connecting lever. The connecting lever is connected with one end of the slide connecting rod through a rotation connecting piece. The other end of the slide connecting rod is combined with a latch hook through a rotation connecting piece. An interlocking buckle is disposed on the cabinet door in a position corresponding to and near the position of the interlocking mechanism. The beneficial effects are that the 10kV high-voltage switch cabinet grounding switch and cable chamber door interlocking mechanism is simple in structure, easy to install and operate and high in reliability, and completely meets the five-prevention requirements of preventing on-load opening or closing a disconnector, mis-opening and mis-closing a circuit breaker, a load switch and a contactor, closing the circuit breaker and the load switch when the grounding switch is in a closed position, mis-closing the grounding switch in a live state, and mis-entering a live chamber.
Description
Technical field
The utility model relates to high-voltage transforming cabinet technical field, especially relates to a kind of 10kV high-voltage board earthed switch and cable chamber door interlocking device.
Background technology
National requirements 10kV high-voltage board need to meet five anti-requirements, and five anti-requirements comprise 1, prevent that on-load from dividing, closing isolating switch.(circuit breaker, on-load switch, contactor "on" position can not disconnecting switch operation) 2, prevent mistake point, close circuit breaker, on-load switch, contactor by mistake.(only have operational order corresponding with operating equipment could to being operated by operating equipment) 3, close circuit breaker, on-load switch while preventing that earthed switch is in the close position.(only have when earthed switch is in gate-dividing state, just can close isolating switch or handcart and just can proceed to service position, could operating breaker, on-load switch closure) 4, prevent from closing earthed switch in charged mistiming, (only at breaker open operation state, could disconnecting switch operation or handcart could retreat to from service position test position, earthed switch just can close) 5, prevent mistakenly entering into charged chamber.(while only having compartment not charged, just can open the door and enter compartment).For satisfied the 5th requirement, there are some problems in existing switch cubicle in power-off and interlocked operation, and for example interlocking is complicated, and the reaction that operates is slow, there will be stuck phenomenon.
The applicant has the inconvenience that sees above-mentioned known existing interlocking mechanism of switch cabinet, adheres to research and innovation, excelsior spirit, in conjunction with practical experience of life, utilizes the method for professional science, proposes an easy-operating solution of safety, therefore proposes this case application.
