1, box-type substation placed on the ground floor should be selected at a high place, not on the lower-lying areas to avoid the rai n poured inside the equipment operation. Pouring a concrete platform in the high and low pressure side of the left gap, to facilitate the laying of the cable into the outlet. Excavation of foundation in case of the litter or mulch piled on the ground must be dug when the real soil, then backfill and consolidate the good soil, then fill with concrete or ballast to ensure a stable foundation.
2, box-type substation grounding and neutral sharing a ground network. Grounding grid is generally the basis of the four corners of the playing ground piles, and then fused. Box-type substation grounding grid must have two reliable connection. Box-type substation operation, you should always check the grounding connections not loose, no rust. Periodic measurement of earth resistance value, the grounding resistance should be less than 4Ω.
3, the box-type substation natural air circulation cooling dominated. Therefore, around it is not illegal heap objects, especially in the transformer room door should not be blocked, but also often to remove the attachments on the shutters ventilation holes to ensure that all electrical equipment does not exceed the maximum allowable temperature.
4, low-voltage circuit breaker trip should check the cause of the trip before try to send. Sent to unsuccessful must be thoroughly to find the cause of the malfunction, rule out the transmission to prevent the accident.
5, box-type transformer high-voltage power distribution room shall be equipped with zinc oxide arrester, installed the way it must be easy to test and disassembly to replace.
6, the ring network switchgear, transformers, surge arresters and other equipment in high voltage electrical installations should be regular visits to maintenance, defects in a timely manner renovation, insulation preventive test on a regular basis. Box-type substation to disable more than three months, and then put into operation should be carried out before the full preventive tests.
7, the replacement of high-voltage fuse breaking capacity, the transformer must be power outages, the operation is necessary to correctly terminate the mechanical linkage, and use insulated operating rod.
8, box-type substation into the cable outlet hole should be blocking to prevent small animals causing the accident.
9, must have a number of high-voltage warning signs of dangerous and electrical equipment nameplate.
