Focus-adjustable light condensing heating deicing device for power transformation equipment and focus adjustment method thereof

Abstract

The invention discloses a focus-adjustable light condensing heating deicing device for power transformation equipment and a focus adjustment method. The device comprises a photon lamp mounting panel, wherein multiple photon lamps are mounted on the front of the photon lamp mounting panel; the photon lamp mounting panel comprises n same isosceles-trapezoid panels; the isosceles-trapezoid panel is formed by movably articulating more than or equal to three sections of sub-trapezoidal plates; n isosceles-trapezoid panels are independently arranged along the circumferential direction and form a regular n-polygon ring; a regular n-polygon plate center is embedded in an inner cavity of the regular n-polygon ring; the sub-trapezoidal plate on the innermost side of each isosceles-trapezoid panel is movably articulated with the plate center through a rotary connection shaft; and a focus adjustment mechanism is arranged on the back of the photon lamp mounting panel and used for automatically adjusting the sub-trapezoidal plates to rotate synchronously to focus the photon lamps. In the method, the curvature of the photon lamp mounting panel is changed by the focus adjustment mechanism, and the focus of the photon lamp changes along to adapt to the actual safe deicing distance. The light condensing focus can be automatically adjusted, and the power-on deicing need of equipment of different safe distances can be met.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and mitigation in electric power systems, in particular to an adjustable focal length concentrating heating and deicing device for power transformation equipment and a focal length adjustment method thereof. Background technique [0002] In southern my country, the winter is low temperature and rainy, and freezing disasters occur frequently. The damage caused by the ice disaster to the substation equipment is very serious. For example, in 2008, the ice disaster in the southern region caused a total of 3 bus failures of 220kV and above substations in Jiangxi Power Grid; six 500kV substations and 30 220kV substations in Hunan Power Grid lost voltage and shut down, and caused a large number of isolating switches, circuit breakers, transformers and other machinery. damage. [0003] At present, there are complete sets of ice-melting methods and devices for substation equipment at home and...

AI Technical Summary

Problems solved by technology

Devices using thermal deicing need to use long insulated hot air pipes to achieve long-distance deicing work. In order to ensure the safety of ice melting, it requires high insulation performance of insulating pipes, so such equipment is usually large in size, resulting in narrow The ability to adapt to space is not strong

Although steam melting ice can also achieve good results, but because the spray is water vapor, it will inevitably reduce the insulation performance of the air gap, so usually only power failure can be used to remove ice, which limits its economic performance

[0004] Patent ZL201320355815.2 proposes a device that installs several high-energy photon lamps on a concentrating panel for concentrating heat and melting ice, which can safely melt ice-covered substation equipment, but the disadvantages are: a single The high-energy photon lamp is a scattered point light source. When it is directly installed on the concentrating panel, there is still a large amount of light scattered, which cannot gather all the light, which will inevitably cause a large amount of energy loss and affect the ice-melting effect.

And its focal length is fixed, the deicing distance is fixed, it is difficult to meet the deicing requirements of substation equipment with different voltage levels and different safety distances
