Abstract

The invention discloses a method for measuring the opening and closing speed of an extra-high voltage vacuum circuit breaker. The method is completed by a device for measuring the opening and closingspeed of the extra-high voltage vacuum circuit breaker. The method comprises the steps that the device is directly placed beside an extra-high voltage vacuum circuit breaker opening and closing side,the outer wall of the extra-high voltage vacuum circuit breaker opening and closing side is sucked through a suction cup, an air pump works to evacuate air in the suction cup to achieve the purpose ofprimary fixing, and a rubber block is fixed and drives a small gear to rotate through a second motor; a sliding block is in sliding connection with a fixing rod in a matched mode, so that a protection plate moves towards the top and the bottom of the shell, a measuring opening is opened, a first motor is started to drive a gear to rotate, a rack moves leftwards, the rack stably slides on a positioning rod in a matched mode through a fixing frame, and a speed sensor can be pushed out of the fixing shell during measurement to achieve measurement; meanwhile, the purpose of protection is furtherachieved through the glass cover during measurement.

Description

technical field [0001] The invention relates to the technical field of UHV vacuum circuit breakers, in particular to a method for measuring opening and closing speeds of UHV vacuum circuit breakers. Background technique [0002] "Vacuum circuit breaker" is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. It is widely used in power grid. Vacuum circuit breaker is an indoor power distribution device in 3-10kV, 50Hz three-phase AC system, which can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations, especially suitable for oil-free, less In places where maintenance and frequent operations are used, circuit breakers can be configured in central cabinets, double-layer cabinets and fixed cabinets to con...
