Abstract

The present invention discloses a 10kV false switching-preventing disconnecting switch lock. The 10kV false switching-preventing disconnecting switch lock comprises a screwing screw rod, a fixed sleeve clamped at the middle portion of the screwing screw rod, an upper portion sleeve being in threaded connection with the upper portion of the screwing screw rod, a lower pile head being in threaded connection with the side portion of the fixed sleeve and an upper pile head being in threaded connection with the side portion of the upper portion sleeve; and the lower portion of the screwing screw rod is movably connected with the upper end of a pull rod. The 10kV false switching-preventing disconnecting switch lock restricts operation for a moving contact, adds a lock on the program of close ofthe disconnecting switch to ensure that the moving contact is perpendicular to the ground and ensure the maximum electrical safe distance for a static contact. The 10kV false switching-preventing disconnecting switch lock employs a common pull rod for operation, and is simple in structure, reliable in performance and convenient to dismount.

Description

technical field [0001] The invention relates to the technical field of distribution network power equipment, in particular to a 10kV anti-mis-close isolating switch lock. Background technique [0002] The isolating switch is a switching device that is mainly used to "isolate power supply, switch operation, connect and cut off small current circuits", and has no arc extinguishing function. When the isolating switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; current switching device. It is generally used as a high-voltage disconnector, that is, a disconnector with a rated voltage above 1kV. Its working principle and structure are relatively simple, but due to the large amount of use and high requirements for working reliability, it is very important for the design, establishment and maintenance of substations and power plants. The impact on safe operation is greater. T...
