一、自动合闸装置的意义备用电源或备用设备自动合闸(以下简称 ABP),系指在工作中的电源线路、变压器或其他设备因故障而被切断后,借某些自动装置(继电器等)将备用电源、线路、变压器或设备自动投入运行,以代替被切断了的电源、线路、变压器或设备。由于石油工厂中绝大部分车间均属第Ⅰ类用户,如果停电将招致设备爆炸或生产废品,因此 ABP 在石油工厂的应用上具有很重大的意义。二、负荷开关的用途及建议应用负荷开关作为 ABP 装置负荷开关是一种轻便型的高压配电设备,优点是比油断路器便宜(与 BMΓ-133价格相差2倍),可以装置的地点如表1所示:
First, the meaning of automatic closing device Backup power supply or backup equipment automatic closing (hereinafter referred to as ABP), refers to the work of the power lines, transformers or other equipment is cut off due to faults, by some automatic devices (relays, etc. ) Standby power, wiring, transformers or equipment are automatically put into operation to replace the cut off power supply, wiring, transformers or equipment. As most workshops in the petroleum plant are Class I users, ABP is of great significance in the application of petroleum plants if the power outage will lead to equipment explosion or production waste. Second, the use of load switches and recommendations Load Switch as ABP load switch device is a portable high-voltage power distribution equipment, the advantage of cheaper than the oil circuit breakers (with BMΓ-133 price difference of 2 times), the device can be installed at locations such as Table 1 shows:
