Abstract

PROBLEM TO BE SOLVED: To provide an electroconductive helmet cover, capable of effectively shading the face in the work in a strong electric field region. SOLUTION: This electroconductive helmet cover 1 having an electroconductive main body 2 has an electroconductive mesh 3 at least covering the face of a worker, installed in the main body 2. The exposed position of a human body is decreased as much as possible by covering the face with the electroconductive mesh 3 to increase the cover rate, and to prevent the unpleasant feeling caused by the induced current.

(Test Example) The shielding ratio was measured using the helmet cover and the conductive work clothes. Diagram of test method
Explanation will be made based on 2. Workers wear conductive work clothes consisting of outerwear and pants and wear a helmet. The conductive work clothes 6 are made of the same material as the main body 2. In that state, stand on the insulating plate, and install a high-voltage conductor at a distance of about 3 m from the head. A voltage of 400 kV is applied to this conductor, and the current flowing through the human body and conductive work clothes is measured. "100x
Current value of work clothes / (current value of human body + current value of work clothes) "
Is the shielding ratio. Then, a comparison was made between the case where the helmet cover of the present invention was worn and the case where the helmet cover without the mesh portion (that is, only the main body) was worn. In addition, the electric field strength of the face was measured.

As a result, in the case of a helmet cover having only the main body, the current value of the work clothes is 485 μA, and the current value of the human body is 41 μA.
A, the shielding rate was 92%, whereas in the helmet cover using the mesh part, the current value of the work clothes was 520 μA, the current value of the human body was 13 μA, and the shielding rate was 98%. Therefore,
It was confirmed that a high shielding rate can be obtained by providing a mesh portion. Regarding the electric field strength on the face, the measured value was 37 V / cm in the case of the helmet cover having only the main body, and was 4 V / cm in the case of using the mesh portion.

As described above, according to the helmet cover of the present invention, by providing the mesh portion for covering the face, the portion where the human body is directly exposed is almost eliminated, and a high shielding ratio of 95% or more can be obtained. At the same time, a strong electric field to the face can be shielded. Therefore, in live-line work of high-voltage wires,
Eliminating discomfort such as tingling of the face can be performed with peace of mind.
