Helmet with electrical field intensity alarming device

Abstract

The invention relates to a helmet, in particular to a helmet with an electrical field intensity alarming device, specifically a safe distance alarming helmet capable of detecting the distance of an electric field, and belongs to the technical field of electric power detecting equipment. According to the technical scheme provided by the invention, the helmet comprises a helmet body, wherein an electrical field intensity detecting device is arranged on the helmet body and electrically connected with a control circuit on the helmet body; the output end of the control circuit is connected with an acoustooptical alarm circuit; and when the electrical field intensity detected by the electrical field intensity detecting device is matched with an alarming electrical field intensity preset in the control circuit, the control circuit makes an acoustooptical alarm through the acoustooptical alarm circuit. The helmet is compact in structure, can prevent an operator from mistakenly entering a charged region, can analyze the intensity of the electrostatic field, and is more convenient to put on and replace, wide in application range, safe and reliable.

Description

technical field [0001] The invention relates to a safety helmet, in particular to a safety helmet with an electric field strength alarm device, specifically a safety helmet with an electric field distance detection safety distance alarm, and belongs to the technical field of electric power detection equipment. Background technique [0002] With the development of the economy, the construction scale of the power grid has developed by leaps and bounds, but it is also facing various security problems. What is particularly prominent is the personal safety and equipment safety of front-line operation and maintenance personnel. How to effectively avoid casualties caused by human errors caused by approaching high-voltage electrified bodies has become an important direction of electric power safety production research. [0003] The closer to the high-voltage charged body, the higher the electric field intensity generated. The proximity detection technology is a safe distance detect...

AI Technical Summary

Problems solved by technology

[0004] Existing products use near-electrical alarm devices, such as wrist alarms, which are similar to watches and can be worn on the wrists of maintenance personnel, but can only perform qualitative alarms, and at the same time the alarm is accurate. The reliability is not high, and false alarms often occur; in the power distribution room of the substation, due to the small space, the alarm often occurs at the entrance, and it can only be judged whether there is electricity in the surrounding tens of meters, and whether the operation and maintenance personnel are really close to the charged body It has almost no effect, cannot effectively avoid the occurrence of accidents, let alone accurately judge the magnitude of the electric field intensity and the distribution trend of the electric field in a specific direction

At the same time, because the equipment is not a must for the operation and maintenance personnel, there are cases where the operation and maintenance personnel do not wear it.

However, the relevant national standards do not make mandatory requirements for the wearing of the equipment, and the operation and maintenance personnel often ignore the wearing of the equipment.
