Optionally, the process of monitoring the pressure of the vacuum arc-extinguishing chamber includes: the pressure of the vacuum arc chamber is monitored by a gas density pressure gauge with auxiliary contacts. Specifically, when the common box type ring main unit is welded with the stainless steel shell, a small hole is reserved for the pressure gauge and is used for facilitating the access of the gas pressure gauge.
Optionally, the process of monitoring the mechanical vibration signal includes: the vibration waveform of the operating mechanism is monitored when the vacuum circuit breaker and the load switch are operated.
Specifically, the vibration waveform can be monitored by using an electric acceleration sensor according to the amplitude of a vibration signal generated in the switching-on and switching-off operation process of the vacuum circuit breaker.

Specifically, the real-time clock chip can be utilized to start timing from the initial operation of the ring main unit, and then the service years of the ring main unit can be monitored.
Specifically, the operation times of the secondary control loop or the auxiliary contact on the operating mechanism can be monitored when the ring main unit is switched on or switched off, and then the use times are monitored.

Optionally, the process of obtaining the current operation state of the ring main unit according to the analysis of the monitoring data includes: and judging whether the opening and closing coil and the switch main loop have line faults according to the opening and closing coil and the switch main loop monitoring data.
Specifically, the current waveform collected during normal operation of the opening and closing coil can be used as a standard for judging whether the current waveform of the opening and closing coil obtained through monitoring is normal or not.
Specifically, the current value and the voltage value collected during normal operation of the opening and closing coil can be used as criteria for judging whether the current and the voltage of the opening and closing coil obtained through monitoring are normal or not.
Specifically, the current value collected during normal operation of the switch main circuit may be used as a criterion for judging whether the current of the switch main circuit obtained by monitoring is normal.
Optionally, the process of obtaining the current operation state of the ring main unit according to the analysis of the monitoring data includes: and judging whether the ring main unit has partial discharge according to the partial discharge monitoring data.

Specifically, whether the current temperature and humidity can increase the line fault risk can be judged according to whether the current temperature and humidity belongs to a preset temperature and humidity range, if so, the line fault risk can be increased, otherwise, the line fault risk cannot be increased.
Optionally, the process of judging whether the ring main unit has the line fault risk increase factor according to the monitoring data of the non-electric quantity factor cabinet includes: and judging whether the current vacuum arc-extinguishing chamber pressure of the ring main unit increases the line fault risk according to the vacuum arc-extinguishing chamber pressure monitoring data obtained by monitoring the vacuum arc-extinguishing chamber pressure.
Specifically, whether the current vacuum arc-extinguishing chamber pressure can increase the line fault risk can be judged according to whether the current vacuum arc-extinguishing chamber pressure belongs to a preset pressure range, if so, the line fault risk can be increased, otherwise, the line fault risk cannot be increased.
Optionally, the process of judging whether the ring main unit has the line fault risk increase factor according to the monitoring data of the non-electric quantity factor cabinet includes: and judging whether the current mechanical vibration condition of the ring main unit increases the line fault risk according to the mechanical vibration signal monitoring data obtained by monitoring the mechanical vibration signal.

Specifically, if the waveforms have a small difference, it is possible to determine that the operation is abnormal, and if the waveforms have a large difference, the operation is in a fault state. Both abnormal actions and fault states increase the risk of line faults, and related personnel need to be prompted.
Optionally, the process of judging whether the ring main unit has the line fault risk increase factor according to the monitoring data of the non-electric quantity factor cabinet includes: and judging whether the current switching contact opening and closing speed of the ring main unit increases the line fault risk according to the switch contact travel-time characteristic monitoring data obtained by monitoring the switch contact travel-time characteristic.
Specifically, the switching contact just-split/just-combined speed, the average speed and the maximum speed can be obtained through calculation according to the switch contact travel-time characteristic monitoring data, namely the travel-time curve of the switch contact, and then whether the current switch contact opening and closing speed of the ring main unit increases the line fault risk can be judged according to whether the just-split/just-combined speed, the average speed and the maximum speed fall into corresponding preset speed ranges or not, if so, the line fault risk cannot be increased, otherwise, the line fault risk cannot be increased.
Specifically, the switching-on and switching-off speed of the switch contact needs to be kept in a reasonable range, impact is easily formed on mechanism components due to too high speed, the arc extinguishing time is too long due to too low speed, and reliable switching-on and switching-off can not be achieved. In addition, the switching machine may experience failures such as partial wear, fatigue, deformation, rust, and slow action of the valve, which may increase the risk of line failure.
