即不是直接从22kV变电站引来，而是多座变电站串接在两座22kV变电站中间，简称为手拉手式闭环连线开环运行结构。正常时，两端电源供电，中间的两座变电站间联络断路器断开。如下图1结构。K1~K4，K6~K1闭合，K5断开，假设左侧22kV变电站停电，变电站1内的备自投无法控制K5，导致变电站1，左侧22kV变电站全站停电。如何解决这一问题，即检测、判断故障，通过何种方式传递、变换站间信息，以便隔离故障，提高供电可靠性，一直是一个难题。

pH计上有两个电极，甘汞参比电极和玻璃电极。甘汞电极用作参比电极，内装饱和KCl溶液，其中应有少量KCl晶体，并保持液面覆盖甘汞柱(充至玻管弯转处)。使用时必须取下侧支上的小胶塞，否则不能起到盐桥的离子交换作用。不用时应将小胶塞和末端胶冒套好。玻璃电极用作pH指示电极，应在有效期内使用。新电极或久置不用时，应在纯水中浸泡至少24小时才能使用。若需经常使用，用后冲洗干净泡在纯水中，长期不用时，应在浸泡后，取出，用滤纸擦干、装盒保存。

【排除方法】按操作程序，须停机几分钟后在高压截止阀处放出多余的制冷剂，此时也能将系统中的残余空气一并放出。制冷系统内有空气【故障分析】空气在制冷系统中会使制冷效率减低，突出的现象是吸、排气压力升高（但排气压力还未超过额定值），压缩机出口至冷凝器进口处温度明显，由于系统内有空气，排气压力、排气温度都升高。【排除方法】可以在停机后几分钟后，连续几次从高压截止阀放出空气，还可以根据实际情况适当充灌一些制冷剂。

业内人士都知道一般仪器仪表产品，在运用前或者运用一段时间后，都需要进行校验，而在校验时，那我们在校验时应该注意哪些问题？下面为您一一阐述。规范量具的精密度要等于被校验量具精密度的1/3~1/4。如校验.5级的量具，宜选用.2级或者.1级的规范表。校验量具是审查量具的示值误差、变差，锐敏度、全路程工夫等能否相符规则的请求。校验时的任务环境应力图相符规则的任务环境，如室温、湿度，电源电压和频次，气源压力、空气压力，电子量具的升压工夫以及装置形式等。
