Background
In China, transmission and transformation projects enter the mature development stage of ultrahigh voltage and ultrahigh voltage alternating current and direct current projects, and a large number of key main transformer devices, namely a series compensation platform, a smoothing reactor, a lightning arrester, an isolating switch, a replacement switch and the like, are arranged in an alternating current transformer substation and a direct current converter station. These large devices are large in size and mass, high in cost, and have a large number of post insulators installed. As the post insulator of the transformer substation is mostly made of ceramic materials, equipment such as an isolating circuit breaker, a lightning arrester and the like of an off-switch and a transformer substation related to the post insulator are damaged and serious in the reciprocating earthquake.
The post insulator mainly exists in two forms in a transformer substation and a converter station, one form is a supporting system for a smoothing reactor and a series compensation platform, the insulator is generally directly connected with a ground foundation and bears generally eccentric load, and the ceramic material is extremely unfavorable. The main reason why the ceramic post insulator is damaged in earthquake is that the adopted material is a brittle material which has a high elastic modulus but poor impact resistance and ductility, and once a micro crack is formed inside, the ceramic post insulator is easy to cause brittle fracture damage in earthquake; the other is a post insulator for a lightning arrester, a disconnecting switch and a support tube bus, which is generally installed on a bracket, and the bracket amplifies the earthquake so that the earthquake intensity received by the bracket is greater than the actual earthquake intensity, and the amplification factor depends on the rigidity of the bracket and the mass of the upper insulator and the tube bus.
For the damage condition of the strut equipment in the earthquake, some researchers carry out vibration isolation and damping researches on the strut equipment. Some researchers at home and abroad apply the one-way limited displacement slidable hardware tool to the connection between the pillar equipment and the tubular bus, and the response of the pillar equipment in the earthquake is reduced by using sliding friction energy consumption; other scholars apply the unidirectional displacement limitless hardware to the connection between the support equipment and the tubular bus, so that the coupling effect between the equipment is reduced, the interaction between the equipment is reduced, and the seismic response is reduced. The utility model discloses the female connecting piece of shock attenuation energy dissipation pipe that relates to relies on the deformation of flexible strap, can provide certain relative displacement redundancy between tub generating line and the equipment on the one hand, on the other hand is because self shape and the length restriction of connecting piece, increase along with axial length under the condition of being drawn at both ends, axial deformation rate can reduce, consequently, relative displacement to the equipment has certain restraint, but because the deformation diminishes gradually, consequently sudden restraint can not appear, the damage to equipment self also can reduce when deforming the energy consumption like this.
