Embodiment Construction

[0009] The specific implementation of the present invention will be described in detail below in conjunction with accompanying drawing and technical scheme, appended figure 1 It is a structural and functional schematic diagram of the present invention. The operating mechanism of the observation device adopts a permanent magnet operating mechanism. The top of the permanent magnet operating mechanism is connected with an insulating pull rod, and the top of the insulating pull rod is connected with a moving contact, so that the movement of the permanent magnet operating mechanism can drive the moving contact to move up and down. tube to prevent leaks. The displacement sensor installed on the side of the permanent magnet operating mechanism is used to track the operating part, measure the change of displacement in real time, and then collect the signal change of the displacement sensor through the control module, so as to obtain the real-time displacement and speed, which realizes...

Abstract

The invention, which belongs to an electrical engineering and mechanical technology field, discloses a vacuum arc observation apparatus capable of being operated with an adjustable speed and relates to a switching device which is used to observe vacuum arc and detect an influence degree of an on-off speed curve to arcing. In an observation apparatus, an upper surface of a permanent magnetic actuator which is taken as an actuator part is connected with an insulating bar. A displacement sensor is installed on a side surface of the permanent magnetic actuator. The permanent magnetic actuator and the displacement sensor are connected with a control module through a control wire respectively. The control module is connected with a high-speed digital camera through the control wire. An upper end of the insulating bar is connected with a moving contact. A static contact, which is vertically and fixedly installed above the moving contact, has a certain gap with the moving contact. According to the invention, a structure is simple, motion dispersibility is small and speed regulation operation is convenient to be realized. The apparatus is economic, reliable and is easy to be maintained. The apparatus is not interfered by an external environment. The apparatus can be used in a production unit of a vacuum interrupter and a test platform of a research institution.

Description

technical field [0001] The invention belongs to the field of electrical engineering and mechanical technology, and relates to a switch device used for observing vacuum arcs and detecting the degree of influence of breaking speed curves on arcing in electric power systems. Background technique [0002] The traditional arc observation device generally observes the arcing of the contacts mainly for the structure of the contacts in the arc extinguishing chamber and the magnetic blow effect. The energy generally comes from the capacitor bank. This kind of arc is of DC pulse type, which cannot fully explain the arcing situation in the power frequency circuit. In addition, the gap trigger system with a fixed opening distance cannot express the influence of the contact speed on the arc extinction, let alone reflect the diffusion response state of the instantaneous speed to the arc. The successful breaking of the vacuum arc needs to go through the process of the arc from the aggrega...
