Problems solved by technology

Traditional substations are often designed with anti-seismic structures or ignoring the impact of earthquakes. Under actual earthquakes, substations are damaged to varying degrees according to the size of the earthquake. Large-scale substations often cause large losses due to earthquakes, which does not conform to the current design concept

Abstract

The invention discloses a transformer substation shock isolation monitoring device which comprises high-damping rubber supports evenly arranged between a transformer and a foundation, and a non-contact sensor is arranged between every two high-damping rubber supports; each high-damping rubber support comprises embedded steel plates symmetrically arranged at the bottom of the transformer and on a foundation and support steel plates arranged on the embedded steel plates, and a plurality of high-damping rubber pads and layered steel plates are alternately arranged between the upper support steelplate and the lower support steel plate. The non-contact sensors accurately and quickly record the displacement condition of a transformer substation under the vibration condition, integrate a power equipment transformer substation, a vibration isolation structure and a monitoring system, are good in vibration isolation effect, accurate and flexible in displacement condition monitoring and convenient to use, and can be widely applied.

Description

technical field [0001] The invention belongs to the field of shock isolation technology, and in particular relates to a shock isolation monitoring device for a substation. Background technique [0002] Substation plays an important role in transforming, concentrating and distributing voltage and current in the power system. In order to ensure the quality of power and the safety of equipment, it is necessary to carry out seismic isolation protection for the substation to ensure the normal operation of the substation. Traditional substations are often designed with anti-seismic structures or ignoring the impact of earthquakes. Under actual earthquakes, substations are damaged to varying degrees according to the size of the earthquake. Large-scale substations often cause large losses due to earthquakes, which does not conform to the current design concept. Therefore, objectively, it is necessary to develop a seismic isolation substation system to overcome the above deficiencies...
