1.我们先来说一点，电磁开关质量不符合要求。首先是一个开关的质量问题，如果本身开关的质量就不行的吧，那就更容易损坏啦。

Let's start by saying that the quality of the electromagnetic switch does not meet the requirements. Firstly, there is a quality issue with the switch. If the quality of the switch itself is not good, it is more likely to be damaged.

2.冬季启动燃气发电机组比较困难，启动时间较长且启动次数较多，易使电磁开关内部的活动触片与两个接线柱的静触头接触不良或烧结在一起。你可以理解为燃气发电机组也需要冬眠。

2. It is difficult to start a gas generator set in winter, with a long start time and a large number of starts, which can easily cause poor contact or sintering between the movable contacts inside the electromagnetic switch and the static contacts of the two terminals. You can understand that gas generators also need to hibernate.

3.用一块蓄电池启动的燃气发电机组，若在冬季启动很困难，可采有两块蓄电池并联启动，其目的是在电压不变的情况下，用增加蓄电池容量的方法对机进行启动，但问题的关键是个别燃气发电机组操作人员将两块蓄电池串联在一起，用增加电压的方法启动沼气发电机组。若电磁开关要求用12V直流电启动，而用24V的蓄电池启动燃气发电机组，就更易使电磁开关内部的活动触片与两个接线柱的静触头接触不良或烧结在一起。

3. If it is difficult to start a gas generator set with a single battery in winter, two batteries can be used in parallel for starting. The purpose is to increase the battery capacity to start the machine while the voltage remains unchanged. However, the key problem is that some gas generator set operators connect the two batteries in series and start the biogas generator set by increasing the voltage. If the electromagnetic switch requires starting with 12V DC power and starting the gas generator set with a 24V battery, it is more likely to cause poor contact or sintering between the movable contacts inside the electromagnetic switch and the static contacts of the two terminals.
