Problems solved by technology

[0002] At present, due to the complexity of the power grid structure, the number and types of equipment are constantly expanding, and the corresponding inspection items and test methods are also increasing, which greatly strengthens the work intensity of inspection and maintenance personnel. Due to the influence of human factors, the workload Under the influence, there will be obvious defects in the safety awareness of the staff, and they will often be negligent and even violate the rules. The most prominent is the occurrence of various electric shock accidents, which have brought great harm to the life safety of the staff.

Embodiment 1

[0034] The device can be applied to large-scale construction machinery and equipment. For example, in substations, converter stations and other power transmission and transformation units, spring inspections, autumn inspections, and annual inspections are carried out every year, and vehicles such as cranes and aerial work vehicles are often used around live equipment. , once the boom operator is negligent or misjudged, it is easy to cause the boom to touch the live equipment, causing personal injury and death, accidents and power outages. Alarm, when the boom head of the crane with the alarm probe installed is close to a certain range of high-voltage wires, the alarm will send out an audible and visual alarm to remind the crane operator to operate carefully and reduce the probability of accidents caused by careless operation to a certain extent. The application method of the device is:

[0035] 1) Before the first use, charge the detection probe and the receiver for 12 hours, ...

Embodiment 2

[0043] This device can be applied to some portable equipment for electric inspection, such as ground rod, electric inspection rod, and high-voltage shaker. The staff need to deal with live equipment frequently in the work of power maintenance or power distribution operation, and over time, the charged body and Safety requirements lead to contempt, and accidents still cannot be avoided. At this time, these portable electric testing devices can remind the staff to pay attention to the safe working distance anytime and anywhere. Taking the electric testing stick as an example, the application method of the device is as follows:

[0044] 1) Before the first use, charge the detection probe and the receiver for 12 hours, and then charge it every 24 hours for 10 to 12 hours or the charging indicator goes out if continuous work is required;

[0045] 2) Take out the detection probe and receiver, and turn on the power of the receiver, see if the switch buzzer emits a "beep" sound, and ob...

Abstract

The invention provides a wireless electricity-approaching alarm device through induction of an electric field and a working method. The alarm device depends on an electric field intensity sensor; in the operation process of the electric field around high voltage power lines, the sensor detects electric field intensity signals around in real time, and induces current signals; after filtering and magnification treatment, the signals enter a processor after A/D conversion; if the signals are greater than alarming threshold values, the processor can send out alarming mark signals through a wireless module; the alarm device can send out acousto-optic hints when receiving the alarm instructions. According to the device and the used technical scheme related to the invention, the quick and accurate identification of the electric field can be realized, the device can be used for reminding working personnel of the improvement of self safety consciousness, and the device can be extensively applied to the construction operation nearby high-voltage alive circuits with 100 KV or above, the loss of the personnel and equipment can be reduced effectively, and the safety protective ability of electricity enterprises can be improved.

Description

technical field [0001] The invention relates to the technical field of proximity alarms, in particular to an electric field induction wireless proximity alarm device and a working method. Background technique [0002] At present, due to the complexity of the power grid structure, the number and types of equipment are constantly expanding, and the corresponding inspection items and test methods are also increasing, which greatly strengthens the work intensity of inspection and maintenance personnel. Due to the influence of human factors, the workload In a big way, the staff's safety awareness will have obvious defects, and they will often be negligent, and even operate in violation of regulations. The most prominent is the occurrence of various electric shock accidents, which have brought great harm to the safety of personnel. [0003] According to the national GBT12720 power frequency electric field measurement standard, when a single-phase voltage source is connecte...
