摘要
小型变配电所在选择通风方式时,常会因成本考虑及对设备通风散热需求的低估,而单纯选用自然通风方式进行散热,由此导致设备耗损增加、效率降低、寿命缩短,甚至造成设备停机事故。以Z矿变电所通风设计改造为例,对小型变电所通风方式选择进行了针对性系统分析,并在方案比选的基础之上,对该类通风设计工作提出了相应的优化建议。
When selecting the ventilation mode of small distribution, usually because of the cost considerations and underestimate of the demand of ventilation and heat dissipation, simply natural ventilation to dissipate heat is adopted. Thus, the wastage of the equipments is increased, the eglciency is reduced, the life span is shortened, and even the equipments are forced to stop. Taking Z mine substation ventilation reform design as an example, the choice of the ventilation mode of small substation was analyzed in details and pertinence, and on the basis of scheme comparison, some corresponding optimized suggestions were proposed on the ventilation design works.
