Description
Technical Field
The invention belongs to the technical field of damping and shock absorption, and particularly relates to a damper shock absorption system based on planar pillar equipment of a transformer substation.
Background
China is located between two earthquake zones in the world, namely the Pacific earthquake zone and the Eurasia earthquake zone, and earthquakes are very active. As a country with frequent earthquakes, the earthquake disasters have great threat to substation equipment. A large number of cantilever support column type devices exist in a transformer substation, in order to meet the requirement of electrical insulation safety distance, a certain distance is needed between the support column type electrical devices and the ground, steel supports are generally adopted for connection and installation, and the supports have obvious amplification effect on input earthquakes. Due to the limitation of material characteristics and structural characteristics, the existing structural form of the pillar type electrical equipment is difficult to change, and conventionally, the structural parts of the equipment are generally reinforced to resist strong earthquake action and improve the earthquake resistance of the electrical equipment.
The existing transformer substations at home and abroad adopt a damping technology to reduce earthquake input and earthquake energy dissipation of equipment, so that the structural integrity of pillar type electrical equipment under strong earthquake can be ensured, the basic functions of the electrical equipment in normal operation are not influenced, and the effectiveness of the electrical equipment is verified. But at present, the damping technology is mainly applied to single-body strut equipment. In the case of a planar device having a plurality of legs, such as a disconnecting switch and a circuit breaker, since there is a possibility that the actual seismic excitation may occur in any horizontal direction, it is necessary to simultaneously damp the vibration in both the plane of the device and the direction orthogonal thereto. However, the existing damping technical scheme has obvious defects:
1. if each strut of the equipment is only subjected to shock absorption, the economic cost is high;
2. the damping scheme which does not take the whole equipment as an object may cause that the relative displacement between different struts is larger than that before damping, so that the lead between the equipment is pulled and damaged under the action of an earthquake;
3. if an additional damping device is installed on the whole equipment, the existing damping arrangement scheme only can effectively damp in the plane direction aiming at the structural form of the plane type equipment;
4. in the out-of-plane direction, there is no significant relative motion between the parts of the apparatus, so it is difficult to produce a good damping effect by the damping device.
Therefore, the orthogonal bidirectional damping technical scheme designed for the planar strut equipment is of great significance.
