The invention discloses an electronic power soft
starter, and relates to the technical field of
power equipment soft start, the electronic power soft
starter comprises a
silicon controlled
rectifier heat dissipation
system, a
silicon controlled
rectifier trigger
system and a soft start
control system, the
silicon controlled
rectifier heat dissipation
system adopts a double heat dissipation mode of
oil immersion and
water cooling, and three-phase six
silicon controlled rectifier elements are immersed in insulating oil; the bottom of the oil box is placed in the water box; according to the
silicon controlled rectifier trigger system, two silicon controlled rectifiers in each phase are connected in anti-parallel and are connected with
relay coils through buttons, and contacts of relays are connected with control electrodes of the silicon controlled rectifiers. According to the electronic type
electric power soft
starter, a contactless spark design is adopted, sparks generated by a traditional mechanical
contact type starter are effectively avoided, and the safety production level is improved; and meanwhile, the short-circuit instantaneous breaking protection
circuit breaker is adopted, so that the safety protection performance of the equipment is further enhanced. The heat dissipation mode is innovative,
oil immersion and
water cooling are combined, the heat dissipation cost is reduced, and hot water can be recycled.
