Embodiment 1

[0048] Such as Figure 1-2 As shown, the embodiment of the present invention provides an LTE-based power distribution cabinet safety monitoring method, which includes the following steps:

[0049]S10, divide all the switchgears into grades, including one master switchgear, several intermediate switchgears and several terminal switchgears; one master switchgear is correspondingly connected with two intermediate Connect two intermediate switch cabinets or two terminal switch cabinets to form a parent-child level, and each terminal switch cabinet is connected to a user equipment;

[0050] S20, collect the branch current and branch electric energy of each branch of each switch cabinet in real time;

[0051] S30, edit the data packet according to the branch current and the branch electric energy, send it to the controller through the LTE network server for data analysis, and send the power analysis result to the remote monitoring platform for display.

[0052] Specifically, step ...

Embodiment 2

[0063] On the basis of Embodiment 1, the embodiment of the present invention is used to provide a preferred implementation manner of electric leakage detection. The LTE-based power distribution cabinet safety monitoring method further includes the steps of:

[0064] S41, obtaining a trigger signal of a trigger connected to the zero-sequence current transformer on the switch cabinet, and judging whether there is an electric leakage;

[0065] S42, obtaining the current value of the leakage protector of the main control switch on the switch cabinet;

[0066] S43. Perform leakage analysis by combining the trigger signal and the current value of the leakage protector: if the trigger signal shows leakage and the current value of the leakage protector is 0, it is determined to be leakage, and a leakage warning is output.

[0067] In this embodiment, leakage analysis is performed by setting a trigger connected to the switch cabinet and a zero-sequence current transformer, and at the ...

Embodiment 3

[0069] On the basis of Embodiment 1-2, the embodiment of the present invention is used to provide a preferred implementation manner of data update. The LTE-based power distribution cabinet safety monitoring method further includes the step of: updating data packets and power consumption analysis every second cycle. Set regular update data packet data sending and receiving and power consumption analysis results to ensure the timeliness of monitoring. As a further optimization, the second cycle can be set to 300 seconds, so that the power consumption of the power distribution cabinet can be monitored all-weather and without omission. Improve the safety factor of electricity use and the efficiency of inspection work.

Abstract

The invention discloses a power distribution cabinet safety monitoring method based on LTE. The method comprises the following steps: grading and dividing all switch cabinets into a main switch cabinet, a plurality of intermediate switch cabinets and a plurality of terminal switch cabinets; wherein one main switch cabinet is correspondingly connected with two intermediate switch cabinets to form a parent-child level, and one intermediate switch cabinet is correspondingly connected with two intermediate switch cabinets or two terminal switch cabinets to form a parent-child level; collecting branch current and branch electric energy of each switch cabinet in real time; editing a data packet, sending the edited data packet to a controller through an LTE network server for data analysis, obtaining a power utilization analysis result, and sending the power utilization analysis result to a remote monitoring platform for display; wherein if the in-phase current difference value of the parent and the child exceeds a current threshold value, the power consumption attribute is private random connection, and if the in-phase current difference value of the parent and the child does not exceed the current threshold value, the increment difference value of the electric energy is the line loss value. According to the invention, the power utilization of the power distribution cabinet can be monitored in an all-weather and no-omission manner, and the power utilization safety coefficient and the inspection work efficiency are improved.

Description

technical field [0001] The present invention relates to the technical field of switch cabinets, and more specifically, the present invention relates to an LTE-based power distribution cabinet safety monitoring method and system. Background technique [0002] Switchgear is a kind of electrical equipment and an indispensable part of the power supply and distribution system. It is widely used in the power supply and distribution systems of the national grid, construction sites and communities, and has a huge potential user market. With the modernization of cities and the urbanization of rural areas, people are paying more and more attention to the safety of electricity use. However, phenomena such as unauthorized connection and cable leakage still occur frequently, and there are potential safety hazards. In order to be able to prevent accidents in advance, it is impossible to meet the market demand and the cost will increase by relying on safety personnel inspection alone. Ther...
