A linkage control device and control method thereof

Abstract

A linkage control device comprises a pole-mounted vacuum circuit breaker body, a remote controller and a monitoring center. A manual opening and closing handle is arranged on the pole-mounted vacuum circuit breaker body. A rotating mechanism is arranged under the manual opening and closing handle. The rotating mechanism comprises a rotating shaft and rotating discs arranged at the ends of the rotating shaft. The two ends of the manual opening and closing handle are symmetrically connected to the rotating discs through extension springs respectively. The rotating mechanism is internally provided with a detection controller interlocked with a pole-mounted vacuum circuit breaker closing coil and the remote controller. The detection controller is arranged on the side of the rotating shaft. According to the linkage control device of the structure, after the outdoor on-site manual opening operation is performed, the pole-mounted vacuum circuit breaker closing coil and the remote controller are automatically powered off, false switching of the pole-mounted vacuum circuit breaker is effectively and completely eradicated, and the life safety of outdoor workers is ensured; after outdoor on-site manual closing operation is performed, the pole-mounted vacuum circuit breaker closing coil and the remote controller can be automatically powered on, and normal remote operation is ensured.

Description

technical field [0001] The invention relates to the technical field of electrical control equipment, and more specifically refers to a linkage control device and a control method for an outdoor pole-mounted vacuum circuit breaker. Background technique [0002] Outdoor pole-mounted vacuum circuit breakers are often used in rural power grids and urban power grid systems for switching and closing load currents, overload currents and short-circuit currents. At present, the Chinese invention patent with the publication number CN 203910663 U discloses a pole-mounted vacuum circuit breaker, which includes a pole-mounted vacuum circuit breaker body. Connected with the main box, the main box is equipped with a manual opening and closing handle, an energy storage handle and an opening and closing indicating box, and also includes an operating mechanism and a control mechanism. The operating mechanism is located in the main box and is connected with the manual opening and closing handl...
