目前,机台照明广泛使用直流发电机.众所周知,直流发电机的电枢由原动机带动,电枢的导线切割发电机的主磁极磁场而产生交变感应电势,通过整流子换向,输出直流电.由于整流子维修困难,常影响钻机夜班生产.我们用滑环代替整流子,对直流发电机进行了两种方案的改制,具有结构简单,重量减轻,维修方便等优点.一将复激直流发电机改成硅整流发电机从充分利用原机的励磁绕组出发,保留原机串激电流与负载同时增减、自动维持发 At present, DC lighting is widely used in machine lighting.It is well-known that the armature of DC generator is driven by a prime mover and the armature wire cuts the main magnetic field of a generator to produce alternating induction potential, commutating commutator, DC output Due to the difficulty of commutator maintenance, it often affects the nighttime production of the drilling rig.We use the slip ring instead of the commutator to make two schemes to the DC generator.It has the advantages of simple structure, weight, easy maintenance, Generator into a silicon rectifier generator from the full use of the original excitation winding set aside to retain the original series current and load current increase or decrease, automatically maintain the hair
