东风型内燃机车上使用的NHZ-110型电阻制动转换器(HK),在运用中经常发生主触头烧损的故障。造成机车临修多、碎修多,HK落修率高。这一惯性故障在我段的机车上更为突出,有的HK装车后使用1～2个定修期就因主触头烧损而落修,有的机车在一个架修期内落修几次制动转换器。这一惯性故障给机车的检修工作增加了许多工作量,影响了机车的正常运用。这一惯性故障是我段多年来的攻关项目之一。
The NHZ-110 type resistance brake converter (HK) used on the Dongfeng diesel locomotive often has the trouble of burning the main contact in use. Locomotive repair more than caused more broken broken repair, HK fell out rate is high. This inertia failure in my paragraph more prominent locomotives, and some HK loading after the use of 1 to 2 repair on the main contact due to burning down and repair, and some locomotive repair fell within a framework Several brake converter. This inertia failure to the locomotive maintenance work increased a lot of workload, affecting the normal operation of the locomotive. This inertia failure is one of my key projects over the years.
