客车电热采暖装置的优点如下: ①便于开关控制; ②采暖效果均匀; ③可取消机车采暖用的蒸汽锅炉(SG),减轻重量,简化维修及保养。因此,电热采暖装置得到了大力推广。但是,由于客车须在非电气化区段及直流电气化区段运用,所以,目前在采用电热采暖的同时应保留原蒸汽采暖装置。一、电热采暖系统电热采暖的电源可以按电源方式和电热采暖装置电源来区分。 1.电源方式 (1)单相1500V电源来自电力机车的电源,通过连接器,再由变压器(装设在车辆地板下,10或30kVA)
The advantages of bus electric heating device are as follows: ① easy to switch control; ② uniform heating effect; ③ cancel the steam boiler (SG) for locomotive heating, reduce weight and simplify maintenance and repair. Therefore, the electric heating device has been vigorously promoted. However, since passenger cars are required to be used in the non-electrified zone and the DC electrified zone, the original steam heating system should be kept at the same time using electric heating. First, the electric heating system Electric heating heating power supply and electric heating devices can be distinguished by the way. 1. Power supply (1) Single-phase 1500V power from the electric locomotive power supply, through the connector, and then by the transformer (installed in the vehicle floor, 10 or 30kVA)
