1、 锅炉房供电系统高压电源的选择供热锅炉房工程直接关系到普通百姓的正常生活，它的重要性是显而易见的；另外，由于在系统正常运行时，如果系统停电，直接威胁外网供水管路的安全，所以根据当地的实际情况，该系统采用双回 10kv 电源，一回运行，一回备用。Heating boiler room project is directly related to the normal life of the common people, its importance is obvious; In addition, due to the system during normal operation, if the
2、 system outage, direct threat to the safety of water supply pipes network, so according to local actual situation, the system USES double 10 kv power supply, one run, one standby. 3 低压供电系统方案的确定http:/ http:/ http:/ http:/ 3 the scheme determination of low voltage power supply system. 3.1 负荷初步统计3.1 lo
3、ad preliminary statistics 补偿前各设备组的计算负荷Before the compensation calculation load of each equipment set 一号锅炉的计算负荷为 773.2 kw；二号锅炉的计算负荷为 773.2 kw；公共部分的计算负荷为 330.65 kw。Computational load of boiler no. 1 to 773.2 kw; No. 2 boiler in the computational load of 773.2 kw; The public http:/ http:/ http:/ http:/
4、 part of the calculation load is 330.65 kw. 3.2 初步确定低压供电系统方案3.2 preliminary determine low-voltage power supply system 由于锅炉房系统运行本身的高可靠性，要求系统在一台炉故障或供电系统部分故障等严重的情况下，应保证不造成大的经济损失，并能维持系统最基本的运行。如在全部或部分锅炉故障的情况下，最基本的要求是要保证水循环系统的正常运行，否则有冻坏管路的危险，造成的损失可能是无法弥补的。反应在供电系统方面，就需要选用两台变压器分列运行的系统，并设置联络开关，这样，在一台变压器故障的情况
5、下，另一台变压器可保证供暖系统最基本的运行。另外考虑到每台锅炉系统运行的可靠性，每台锅炉的负荷应由一台变压器供电。Due to the high reliability of the boiler system operation for system failure or a power supply system in a furnace parts under severe conditions such as fault, shall ensure that do http:/ http:/ http:/ http:/ not cause large economic loss, an
6、d can maintain the basic operation system. As in the case of all or part of the boiler failure, the most basic requirement is to guarantee the normal operation of the water cycle system, or are in danger of freezing pipes, the cause of the loss may be irreparable. Response in terms of power supply s
7、ystem, you need to choose two transformers were operating system, and set up the contact switch, so, in the case of a transformer fault, the other a transformer can guarantee the operation of heating system is the most basic. Also considering the per boiler system running reliability, per boiler loa
8、d should be powered by a transformer. 3.3 负荷统计及变压器的选择并确定低压供电系统3.3 the load statistics and the choice of transformer and low voltage power supply system were determined. 根据以上的思想及负荷的初步统计结果，按两台变压器进行负荷计算，一台变压器（一号变压器）负责一号锅炉的供电，另一台变压器（二号变压器）负责二号锅炉http:/ http:/ http:/ http:/ 的供电。公共部分的负荷由原有的一台变压供电。无功补偿采用自动补
9、偿屏。According to the above thoughts and the preliminary results of load, load calculation according to two transformer, a transformer transformer (1) is responsible for boiler no. 1 power supply, another transformer (transformer 2) is responsible for no. 2 boiler of the power supply. The public part
10、of the load from the original a variable pressure power supply. Reactive power compensation using automatic compensation. 由此可见，选用两台变压器分列同时运行，并互为备用的方案，满足生产过程中对供电系统可靠性的要求。具体见下图“锅炉房供 电系统图” 。So, choose two transformers were running at the same time, as spare and solutions, to meet the requirements of th
