Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
Along with more and more electric equipment of each line of industry, the increase of electric equipment has brought the increase of power consumption, and then more and uncertain power consumption potential safety hazard have improved the requirement to power consumption potential safety hazard monitoring.
The inventor finds that the device which can realize the monitoring function of the working data of the circuit breaker on the market at present is provided with a multi-loop monitoring (energy-saving) system and a novel intelligent air switch (the air switch is additionally provided with an electric parameter, a temperature detection controller and a sensor on the basis of the traditional air switch).
The first kind of multi-loop monitoring (energy saving) system monitors the power consumption data of each power consumption sub-loop, such as sub-loop current, total loop voltage, sub-loop power consumption, etc., and is suitable for the reconstruction of the existing (old/new) switchboard. The system lacks monitoring the voltage of each sub-loop, and the function cannot accurately judge the open-close and open-close states when the loops do not have equipment to run; when the branch loop node is in virtual connection to cause the line temperature to be too high, the system cannot monitor the state, cannot realize the alarm reminding function, and puts down potential safety hazards for the life of production.

When the loop installation is more, the system has the problems of long field installation time, high installation difficulty, complex installation, high construction cost and the like.
The second intelligent air switch can monitor the voltage, current and other electricity utilization data of each sub-loop and the temperature of an air switch internal node, and the system is suitable for newly-built (new-type) switchboards. The intelligent air switch is provided with a corresponding sensor on the basis of the traditional air switch, so that the volume of the intelligent air switch is larger than that of the traditional air switch, the intelligent air switch can be directly used in a newly-built switchboard, but the intelligent air switch has the problem that the traditional (old) switchboard cannot be modified (installed); if adopt independent configuration intelligence air-break case, through corresponding sub-circuit cable of extension and the air-break case of intelligence, though can solve the installation problem, but the sub-circuit adopts the extension line mode, can bring node connection potential safety hazard and multiple cable matching problem, and this mode installation degree of difficulty is big, and on-the-spot installation time overlength, and it is complicated to communicate with the first side, and construction cost is high, later stage (after the maintenance) maintenance difficulty (nonprofessional person maintains the degree of difficulty and increases) scheduling problem.

After the acquisition part is finished, the acquisition controller 2 stores the voltage, current and temperature values into the first row and the first circuit breaker data unit; after the storage is finished, the acquisition controller 2 compares the acquired voltage, current and temperature values with the alarm threshold values of the built-in first row and first circuit breaker, when the acquired values exceed the alarm threshold values of the first row and the first circuit breaker, the sound and light alarm part 23 immediately alarms by sound and light, the alarm position (the first row and the first circuit breaker) is marked, and after the alarm is eliminated, the sound and light alarm part 23 stops alarming.
The Z-direction telescopic mechanism returns to the original position, the acquisition controller 2 extracts position coordinate values (X2/Y1/Z) of the first row of circuit breakers and the second circuit breaker, the acquisition controller 2 sends instructions to the X-direction walking mechanism and the Y-direction walking mechanism, and the X-direction walking mechanism and the Y-direction walking mechanism run in place; the acquisition controller 2 sends an instruction to the Z-direction telescopic adjusting mechanism, after the Z-direction telescopic adjusting mechanism runs in place, the electricity utilization data monitoring device 1 (the current acquisition part 6, the voltage acquisition part 7 and the line temperature acquisition part 12) acquires electricity utilization data information, and the subsequent steps are also like the working process of the first row and the first circuit breaker. And the monitoring on the nth row and nth breaker is completed.
After the first period of the monitoring and early warning device is completed, the Z-direction telescopic adjusting mechanism, the X-direction walking mechanism and the Y-direction walking mechanism return to the initial positions, and the monitoring and operation in the second period is started at the subsequent time.
