Background technology
The fast transient overvoltage (VFTO) producing due to isolator operation likely reaches very high amplitude and rising steepness, has special harmfulness. The main arrester that adopts in extra-high voltage GIS, can limit the amplitude of VFTO, but can not effectively limit its steepness at present; The isolating switch of employing with opening and closing resistor suppresses VFTO, and it exists the shortcoming of the easy fault of complex structure. Even repeatedly occur because of main contact in time short circuit switching-on resistance cause switching-on resistance guarantee, and then damage other equipment, its security is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of fast transient overvoltage of producing due to disconnecting switch operation of can suppressing, ferrite bead is installed on the conductor at isolating switch two ends and can be effectively reduced the amplitude of VFTO and the steepness of rising, ensure that the inhibition isolator operation of the safe operation of high-tension switch gear produces the device of VFTO
When the utility model, realize like this, it includes disc insulator, housing, shielding construction, ferrite bead, pad, contact connecting device and high-voltage conductive rod, it is characterized in that: on high-voltage conductive rod, be provided with ferrite bead string, between ferrite bead, be separated by with pad, shielding construction, ferrite bead, pad and contact apparatus are placed in the housing that is filled with sulfur hexafluoride gas.
The utility model provides a kind of high-tension switch gear ferrite magnetic loop device with the VFTO ability that suppresses isolator operation generation, on conductor, placing ferrite bead is equivalent to and in conductor, accesses an inductance in parallel and resistance, can the wave propagation of damping row, suppress fast transient process, can reduce the number of times repeatedly puncturing, reduce the probability of occurrence of serious VFTO, open up a new way for suppressing VFTO. There is simple in structure, dependable performance, good economy performance, be applicable to each electric pressure, be particularly useful for the advantage of the switchgear of super-pressure or extra-high voltage electric power system.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation that suppresses the device of isolator operation generation VFTO.
Detailed description of the invention
As shown in Figure 1, the device that this inhibition isolator operation produces VFTO includes disc insulator 1, housing 2, shielding construction 3, ferrite bead 4, pad 5, contact connecting device 6 and high-voltage conductive rod 7, it is characterized in that on high-voltage conductive rod 7 are provided with ferrite bead string 4, between ferrite bead 4, be separated by with pad 5, shielding construction 3, ferrite bead 4, pad 5 and contact apparatus 6 are placed in the housing 2 that is filled with sulfur hexafluoride gas; In order to ensure insulating properties, the end of shielding construction 3 is multi-section circular arc rounding off; Have the hole of improving its heat dispersion at shielding construction place. Shielding construction 3 can improve Electric Field Distribution situation, and shielding construction 3 perforates are to improve its heat dispersion.
