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 consumption telescopic tubular bus for a transformer substation. The wave-shaped sliding friction energy consumption telescopic tubular bus comprises a large-diameter tubular bus, a small-diameter tubular bus, an energy consumption sheet and a compensation assembly, wherein the large-diameter tubular bus comprises a large-diameter end plate which is detachably connected in the large-diameter tubular bus; the small-diameter tube bus is internally provided with a wave-shaped sliding groove; the energy consumption sheet is arranged in the small-diameter tubular bus and is inserted into the wave-shaped sliding groove; and one end of the compensation assembly is connected with the energy consumption sheet, and the other end of the compensation assembly is connected with the large-diameter end plate so as to compensate small deformation of the large-diameter tubular bus and the small-diameter tubular bus. Under small earthquakes, the compensation assembly works, the energy consumption sheet and the wave-shaped sliding groove are protected against relative displacement, the energy consumption sheet does not generate plastic deformation, replacement is not needed, and the energy consumption sheet can be continuously used; under a large earthquake, the energy consumption sheet interact with the wave-shaped sliding groove, the energy consumption sheet is plastically deformed, large damping is provided, and the good anti-seismic capacity is achieved; and the expansion only occurs in the bus, so that the disturbance to the electrical equipment is small, the anti-seismic performance of the electrical equipment is improved, and the electrical stability of the electrical equipment is ensured.

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...
