Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
The vibration detection device of GIS under a kind of dry run operating condition, including " returning " shell body 1, and be placed in shell 1
GIS guide rod 2;The both ends of GIS guide rod 2 are connected by connecting rod 5.GIS guide rod 2 is fixed by disc insulator 4 and shell 1, and absolutely
Edge 4 is fixed by insulated bolt and shell 1;Shell 1 is externally provided with the vibrating sensor 8 being connected with oscillograph 9.
The current lifting device 3 outside shell 1 is socketed on as the power supply of GIS guide rod 2, carries out the application of current signal.
SF6Gas-insulated power frequency testing transformer and GIS guide rod 2 share a metal shell, High voltage output directly with height
Guide rod is pressed to be connected.
Connecting rod replaces one section of guide rod, the variation to the conductor size at Simulated GlS contact.
In actual GIS, the positions such as disconnecting switch, contact of breaker can have the discontinuous of conductor size, this to lead
The position that body size mutates can generate vibration due to current constriction.It can be true with one section of thickness and the adjustable connecting rod of length
It is real to simulate such situation, the simulation of different degrees of current constriction is realized by the thickness and length that adjust connecting rod.
