Description

A kind of arrester ground fault monitoring device based on Internet of Things Network Communication
Technical field
The invention belongs to surge arrester failure monitoring device technical fields, and in particular to a kind of lightning-arrest based on Internet of Things Network Communication Device ground fault detection device.
Background technique
Arrester is the important protection equipment of distribution line, connects between distribution line and the earth, usually sets with by protection It is standby in parallel.When distribution line and equipment are run under normal working voltage, arrester will not generate effect, to being greatly considered as out Road;When high voltage occur and jeopardizing distribution line and protected device insulation, arrester starts immediately, presents compared with low resistance High-voltage impact conduct current the earth to limit voltage magnitude, is protected distribution line and protected device insulation by value;When After high voltage disappears, arrester restores to the original state rapidly, works normally distribution line and equipment.
If arrester because lightning stroke or self deterioration are broken down, leads to the reduction of its resistance value, under normal circumstances distribution wire Road generates low current, i.e. arrester ground failure to the earth by arrester, causes to equipment operation and personal safety huge hidden Suffer from, and the failure is difficult to be found.
Summary of the invention
Technical problem solved by the present invention is providing a kind of arrester ground malfunction monitoring dress based on Internet of Things Network Communication It sets, to solve above-mentioned problems of the prior art.
The technical scheme adopted by the invention is as follows: a kind of arrester ground fault monitoring device based on Internet of Things Network Communication, packet Current monitoring module, MCU module, failure indication module and remote communication module are included, current monitoring module is electrically connected to MCU module Signal receiving end, the control terminal of MCU module is electrically connected to failure indication module, and remote communication module is electrically connected to MCU module Communication ends.
Preferably, above-mentioned MCU module is electrically connected to working power module.
Preferably, above-mentioned current monitoring module built-in current mutual inductor, it is primary that arrester downlead passes through current transformer Side, Current Transformer Secondary side conducting wire access MCU module.
Preferably, above-mentioned working power module uses rechargeable battery, and rechargeable battery is connected to too by charging module It is positive can solar panel and, for giving MCU module to provide working power.
Preferably, above-mentioned fault detector module uses LED light emitting diode.
Preferably, above-mentioned remote communication module uses NB-IOT mould group.
Beneficial effects of the present invention: compared with prior art, the present invention by monitoring acquisition arrester downlead on whether There are electric current generation and current value size, to judge whether arrester has ground fault, to realize the real-time of arrester operation Monitoring, and the Internet of Things communication technology is utilized, fault message is sent to long-range main website system, in order to which operation maintenance personnel is timely Arrester ground failure is checked and excluded, the safety in utilization of arrester is greatly improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of fault monitoring device of the present invention;
Fig. 2 is the current monitoring structural schematic diagram of arrester downlead of the present invention.
Specific embodiment
With reference to the accompanying drawing and the present invention is described further in specific embodiment.
Embodiment 1: as Figure 1-Figure 2, a kind of arrester ground fault monitoring device based on Internet of Things Network Communication, including Current monitoring module, MCU module, failure indication module and remote communication module, current monitoring module are electrically connected to MCU module Signal receiving end, the control terminal of MCU module are electrically connected to failure indication module, and remote communication module is electrically connected to MCU module Communication ends.
Preferably, above-mentioned MCU module is electrically connected to working power module.
Preferably, above-mentioned current monitoring module built-in current mutual inductor, it is primary that arrester downlead passes through current transformer Side, Current Transformer Secondary side conducting wire access MCU module.
Preferably, above-mentioned working power module uses rechargeable battery, and rechargeable battery is connected to too by charging module It is positive can solar panel and, for giving MCU module to provide working power.
Preferably, above-mentioned fault detector module uses LED light emitting diode, is used to indicate malfunction.
Preferably, above-mentioned remote communication module uses NB-IOT mould group, which uses general low-power consumption Internet of Things Netcom Letter technology has telecommunication capabilities.
A/D conversion chip, microprocessor chip, LED drive chip built in MCU module, A/D conversion chip and microprocessor Chip bus connection, is converted to digital quantity for the analog quantity for the Current Transformer Secondary side electric current that current monitoring module accesses;It is micro- Processor chips handle the current digital quantity of bus access, judge whether there is arrester ground event by the current value limit value of setting Barrier, microprocessor chip are connected with LED drive chip bus, when differentiating result is arrester ground failure, microprocessor core Piece is lighted failure and is referred to LED drive chip output level variable signal, LED drive chip to failure indication module out-put supply Show the LED light of module.Meanwhile microprocessor chip issues signal of communication to remote communication module, passes through telecommunication mould Fault message is sent to long-range main website system by block.
Example that the above description is merely a specific embodiment, scope of protection of the present invention is not limited thereto.It is ripe It knows the those skilled in the art in the technical scope disclosed by the present invention, change or replacement mode can be easily found, these It should be covered by the protection scope of the present invention.For this purpose, protection scope of the present invention should be with the protection model of the claim Subject to enclosing.
