With the help of some users' multi -level relay, the center station can communicate with each user int he system.
通过用户站的多级接力，中心站可以和每一个用户站进行通信。系统硬件简单，占用频率资源少，成本低。
Flammable gas found in the relay indicates some internal fault such as overheating or arcing, whereas air found in the relay may only indicate low oil level or a leak.
如果在继电器中发现可燃气体，这说明有内部故障，比如过热或者电弧作用；而继电器内的空气只说明油位低或者有漏油。
On a slow accumulation of gas, due perhaps to slight overload, gas produced by decomposition of insulating oil accumulates in the top of the relay and forces the oil level down.
在气体慢积累模式中，可能由于轻微过在，绝缘油分解产生的气体在继电器的顶部聚集，迫使油位下降。
