Problems solved by technology

Due to the size limitation of electrical equipment and its equalizing ring, the slip range of damping fittings is usually small, resulting in limited shock absorption capacity
In addition, the shape of damping fittings is complex, which has a great impact on the electromagnetic field of the substation, and its installation and use range is greatly limited.
Since the busbar is completely nested in the damping fittings, it is necessary to completely pull out the busbar to replace the fitting during the power outage maintenance after the earthquake, and a busbar is often connected to multiple electrical devices. When it is completely pulled out and reinstalled , the large amount of maintenance and commissioning work prolongs the power outage time after the earthquake

Abstract

The invention discloses a wave-shaped sliding friction energy-dissipating telescopic pipe busbar for a substation, which includes a large-diameter pipe busbar, a small-diameter pipe busbar, an energy dissipation sheet and a compensation assembly; the large-diameter pipe busbar includes a large-diameter end plate and a large-diameter end plate It can be detachably connected to the busbar of large-diameter pipes; the busbar of small-diameter pipes is provided with a wave-shaped chute; The large-diameter end plate is connected to compensate the small deformation of the large-diameter pipe busbar and the small-diameter pipe busbar. Under small earthquakes, the compensation components work, and there is no relative displacement between the energy-dissipating sheet and the wave-shaped chute. The grooves interact with each other, the plastic deformation of the energy dissipation sheet provides greater damping, and has better shock resistance; and the expansion and contraction only occurs in the busbar, which has little disturbance to electrical equipment, improves the seismic performance of electrical equipment, and ensures the electrical stability of electrical equipment.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic technology for substation equipment, in particular to a wave-shaped sliding friction energy-dissipating telescopic pipe busbar for a substation. Background technique [0002] High-voltage substations are very important in the power grid. The electrical equipment of substations is usually made of brittle materials such as ceramics or composite materials. The brittleness of materials makes them easy to damage during earthquakes, which can easily cause large-scale power outages in regional and even backbone power grids, causing huge economic losses. loss. [0003] The damage to the power grid will have serious adverse effects on earthquake relief and post-disaster reconstruction work, and even delay the golden 72-hour rescue time after the earthquake. [0004] At present, seismic isolation measures are taken for electrical equipment to protect electrical equipment and improve the safety of powe...
