防爆電機電壓選擇

近年來, 節省能源並減少線路功率損耗, 3KV井下防爆電動機喺石油化工和煤礦開採等行業越嚟越多地用於主軸通風. There’s a growing trend towards choosing LOKV explosion-proof electrical equipment with decreasing power ratings. Some manufacturers have even received orders for LOKV units ranging from 110 to 160KW. 然而, producing LOKV with such lower power ratings increases both the manufacturing costs and difficulties.

When IIA low-voltage explosion-proof motors operate at a frequency of 60Hz, their rated voltage is adjusted to 460V. This transition is easily achieved by domestic 防爆電機 manufacturers from their existing 50Hz products.
