The transformation operation and maintenance room of the Longyan power supply company manages 45 transformer substations, and 21.2 times of alarm signals appear in one week on average, so that the economic cost of the company can be saved by 1000 yuan by 21.2 yuan by 54 weeks which is 114.48 ten thousand yuan. The operation cost of the invention is that the basic communication cost of a telephone card per month is 13 yuan, the cost is 73 yuan 13 yuan 12 yuan 1.1388 ten thousand yuan, the economic cost can be saved in 114.48-1.1388 to 113.34 ten thousand yuan each year, and the indirect profit of the company is 113.34 ten thousand yuan each year.
By combining the calculation, 113.34 ten thousand yuan can be saved by applying the automatic reset device in the transformation operation and maintenance room of the national grid Longyan power supply company.
The economic benefit directly generated by the transformation operation and maintenance room of the state net Longyan power supply company is more considerable if the method is further popularized and applied.
The social benefits of the implementation of the invention are as follows:

(2) the invention can enable the operation and maintenance personnel to reset the substation signals in the operation and maintenance station without taking a bus for traveling, thereby directly avoiding the driving safety risk of the operation and maintenance personnel.
(3) The invention can rapidly complete the alarm signal resetting action. When the monitoring telephone informs the operation and maintenance personnel that the alarm signal needs to be reset, the operation and maintenance personnel do not need to drive the vehicle to arrive at the site (the time consumption of one trip is 0.8-1.5 hours), and the SIM card number arranged on the corresponding alarm device can be immediately dialed to realize the reset action (the time consumption is 1 minute).
(4) For the alarm signal which cannot be automatically reset, the time for the operation and maintenance personnel to reset the signal back and forth is 50-90 minutes, the operation and maintenance personnel works for 8 hours per day, and the operation and maintenance personnel need to occupy one eighth or even more of working time for resetting the signal. The invention can remotely and automatically reset the alarm signals, and can complete the resetting operation in 1 minute, so that operation and maintenance personnel have more time to process other matters, and the operation and maintenance professional human resources are improved.
(5) The GSM technology is applied to power production, the automation level of power production is greatly improved, and the automation step of power production is further promoted.
(6) During rush hours and off duty peak hours, urban roads are very congested, if severe environments such as thunderstorm weather are met, the traffic is more unsmooth, and under the weather, various warning signals are more likely to appear in a power grid system.
(7) The implementation of the invention reduces the driving mileage of the vehicle, reduces the fuel consumption and saves social energy and non-renewable resources.
(8) The implementation of the invention reduces the driving times and mileage of the vehicle, reduces the exhaust gas discharged to the atmosphere, and contributes to the environmental protection construction of cities.
