Description
Technical Field
The invention relates to the technical field of lighting implementation of a substation area, in particular to a novel adjustable projection lamp support for a substation, which is used for daily operation and maintenance work, power-off operation or scheduled inspection site of the substation.
Background
The transformer substation needs the illumination of the station spot light when performing daily operation and maintenance, power-off and switching operation, accident handling, equipment regular switching, equipment regular inspection and the like. The projecting lamp holder, pole setting and the basis that present transformer substation used all are fixed connection, and the lamp holder direction can't be adjusted. Under special working conditions, for example, during night accident handling, operation and maintenance personnel may not clearly check the actual conditions of all parts of equipment due to the fact that a blind area exists in light irradiation, the fault reporting time is delayed, and a person in charge on duty judges the fault condition of the equipment on site, so that the work of power dispatching and accident handling after accident research and judgment analysis and fault occurrence of a power dispatching department is delayed; for example, when a large-scale power failure scheduled inspection site is used, maintenance personnel perform high-altitude operation or replace electrical equipment, the equipment can be collided and scratched or the personnel collide with the equipment and are injured due to poor lighting, and the equipment installed at high altitude is collided and collapsed to cause casualties and equipment damage in severe cases. The poor illumination condition of station district has brought the hidden danger for safety in production, has also reduced the factor of safety of work efficiency and site operation.
According to the survey, most of the transformer substations in the power system are widely used at present and cannot be adjusted, the structure is simple and reliable, the ground area of a total station plant area can be basically covered in the initial station building stage, the investment cost performance is high, and the daily general production needs can be met. However, in an actual production work site, the direction of the fixed projection lamp is usually adjusted by temporarily adding the movable charging projection lamp due to poor illumination, so that the labor carrying cost, the production material input cost and the production preparation work time are greatly increased in use, the production work time is also prolonged, the field use flexibility is not high, and the actual requirements of field work cannot be met by the fixed projection lamp in specific situations.
