Description
Technical field
The present invention relates to a kind of Anti-seismic casing bit and uses thereof.
Background technique
The end of GIS device that casing bit is in (H) upwards needs to be connected with the overhead conductor in power station, needs downwards to be connected with (H) GIS, the multiple action of its undertaker's High-Voltage Insulation load, mechanical load and insulating supporting.Therefore the operation stability of casing bit directly can affect the stability of (H) GIS device overall operation, once casing bit goes wrong will affect the operation of whole electrical network, thus brings huge loss to society and the people.Casing bit, when non-seismic region uses, there will not be problem, but casing bit is when the seismic region that the seismic activity such as Qinghai-Tibet, Tianshan Mountains is frequent and strong uses, and has higher requirement to its operation stability.The casing bit that existing seismic region uses is as shown in Figure 1: comprise support 4, metal cylinder and the vertical spaghetti 1 arranged, spaghetti is generally made up of porcelain or glass fibre reinforced plastics, itself fragility is large, frangible, easily fried, metal cylinder comprises sleeve pipe connector drum 5 and is fixedly arranged on the cylindrical shell 3 in sleeve pipe connector drum, prop up cylindrical shell for being connected with the connector drum in GIS device, existing design concept is: spaghetti will bear, air pressure inside, external wind pressure, outside terminal pulling force, the all directions power brought is accelerated in self gravitation and earthquake, add the thin of spaghetti itself, high, soft, the features such as heavy and cross section is non-linear, spaghetti becomes the weakest link in antidetonation process, the feature of support directly has influence on the dynamic effect coefficient of support to sleeve pipe in seismic experiment, support is higher, the more soft dynamic magnification factor to sleeve pipe is larger, sleeve pipe stressed just harsher.In order to reduce the impact of support on sleeve pipe, usually that the ratio of rigidity of support Design is comparatively large, be directly connected with sleeve bottom.But find through practice: in non-earthquake, this structure can ensure that spaghetti has good performance, but when earthquake, the active force of earthquake can be directly passed to spaghetti by support, because the rigidity difference between support and spaghetti is large, therefore stress just concentrates on the less position of rigidity and spaghetti root, even the vibrations that result is very little, the problem that spaghetti is broken, burst is caused in capital, can not meet antidetonation demand completely.Fig. 1 middle term 2 represents the adpting flange being arranged at spaghetti lower end.
Summary of the invention
The object of the present invention is to provide a kind of Anti-seismic casing bit, to solve in prior art comparatively large and easy broken, the problem that bursts of the spaghetti lower end stress when earthquake; The present invention also aims to the purposes that this Anti-seismic casing bit a kind of is provided.
In order to solve the problem, in the present invention, the technological scheme of Anti-seismic casing bit is:
Anti-seismic casing bit, comprise support, metal sleeve and spaghetti, the lower end of spaghetti is fixed on the upper end of described metal sleeve, the rigidity of metal sleeve is less than the rigidity of support, and the lower end of metal sleeve is fixedly connected with to carry out the vibration of buffering stand to spaghetti by the self-deformation of metal sleeve when earthquake with described support.
Metal sleeve is made up of aluminum alloy, and the wall thickness of metal sleeve is 8 ~ 12mm.
Described metal sleeve comprises the sleeve pipe connector drum be coaxially set with spaghetti and the cylindrical shell be fixedly arranged in sleeve pipe connector drum, and spaghetti coaxial line is fixedly arranged on the upper end of sleeve pipe connector drum, and the lower end of sleeve pipe connector drum is fixedly arranged on the upper end of support.
The lower end of sleeve pipe connector drum is provided with cylindrical shell lower flange, the lower end of cylindrical shell lower flange is provided with the cylindrical shell shrouding be sealed and matched with cylindrical shell lower flange, cylindrical shell lower flange is provided with lower flange bolt penetration hole, cylindrical shell shrouding is provided with the shrouding bolt penetration hole that arrange corresponding to lower flange bolt penetration hole, support is provided with the support bracket bolt that arrange corresponding to shrouding bolt penetration hole to bore a hole, in the perforation of lower flange bolt penetration hole, shrouding bolt penetration hole and support bracket bolt, is coated with lock bolt.
The axis propping up cylindrical shell extends along the longitudinal direction, and support comprises the vertical rack body arranged and the left support abutment and the right support abutment that are arranged at rack body upper end, and support bracket bolt perforation is arranged on left support abutment and right support abutment.
In the present invention, the technological scheme of the purposes of Anti-seismic casing bit is:
Above-mentioned Anti-seismic casing bit is applied in the Insulating A High-Voltage switching device in seismic region, when earthquake, carrys out the vibration of buffering stand to spaghetti by the self-deformation of metal sleeve.
Beneficial effect of the present invention is: in the present invention, metal sleeve is connected between support and spaghetti; the rigidity of metal sleeve is less than the rigidity of support; the rigidity of metal sleeve compares support closer to spaghetti; when earthquake; the effect that metal cylinder is played buffering by the deformation of self and released energy; earthquake stress is discharged by metal sleeve, reduces the Root Stress of spaghetti, the insulator of effective protection.The present invention and conventional design thinking run in the opposite direction, and have abandoned the idea that spaghetti is arranged at guarantee spaghetti intensity on support by tradition, have achieved unforeseeable technique effect.
