Detailed Description
The following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
As described in the background art, when a human body transits from ground potential along an insulation ladder (or an insulator string) into a strong electric field, large potential changes and potential differences exist. When the field intensity exceeds a certain value, dangerous potential difference occurs among all parts of the human body, and the cuticle of the epidermis of the human body can not bear the action of the strong electric field. In order to eliminate the phenomenon of capacitance charge and discharge in the process of potential transfer and weaken the influence of a high-voltage electric field on a human body, when live-line work is carried out on a high-voltage electrified body, the human body needs to wear a shielding clothes.
The shielding clothes are made according to the principle that metal balls are placed in a strong electric field, the electric field inside the shielding clothes is zero (Faraday cage), the shielding clothes are made of tussah silk which is woven uniformly by warps and wefts, and the tussah silk is wrapped with metal wires (stainless steel or copper wires), the shielding clothes are like a special metal net cover, the electric field intensity on the surface of a human body can be uniform and reduced to the minimum by means of the shielding clothes, the electric field shielding efficiency of the good shielding clothes can reach 99.9%, the current flowing through the human body during operation almost completely flows through the shielding clothes, and the current protection of the human body is realized. Under the condition of an accident, the shielding clothes are worn to protect the personal safety, and the shielding clothes also have a certain effect on reducing the area of electric arc burn; the live-wire work can be classified into equipotential work, ground potential work and intermediate potential work according to the position of a human body. When in equipotential operation, the human body directly contacts the high-voltage electrified part. The human body in the high-voltage electric field can have dangerous current flowing through, thus endangering personal safety, therefore all workers entering the high-voltage electric field should wear the whole set of shielding clothes. The live-line work shielding clothes are also called equipotential uniform pressure clothes, and are made of uniform conductor materials and fiber materials. The function of the protective clothing is to form an equipotential shielding surface at each part of the outer surface of the human body in a high-voltage electric field after the protective clothing is worn, thereby protecting the human body from the harm of the high-voltage electric field and electromagnetic waves.
Example 1:
as shown in fig. 1, a charged shield garment capable of carrying a precise positioning device is woven from a plurality of fabric layers and includes a conductive fabric layer. Including shielding clothes body, shielding gloves, shielding face guard and shielding shoes, be equipped with the sack in head, both shoulders, elbow, both hands, buttock both sides, both knees and the thirteen positions of both feet altogether, the sack is directly or through the magic subsides dress establish on the shielding clothes body, sets up the signal antenna that the hole is used for installing positioner on the sack.
The positioning device comprises a positioning module and two groups of signal antennas, wherein the first signal antenna is used for receiving satellite positioning signals, and the second signal antenna is used for sending position information of a positioning device mounting point.
The positioning device of the head is positioned at the top of the head, the positioning devices of the shoulders are positioned at the top of the shoulders, the positioning devices of the elbows are positioned at the outer sides of the elbow joints of the two arms, the positioning devices of the two hands are positioned at the wrists, the positioning devices of the buttocks are positioned at the two sides of the buttocks, the positioning devices of the two knees are positioned at the outer sides of the knee joints, and the positioning devices of the two feet are positioned at the feet.
The power is located the back of shielding clothes body, and the power passes through the power cord and supplies power for positioner, and the power outside has vest type shielding cover.
For example: the dotted line in figure 1 is the power supply line of the positioning device, the material of the shielding sleeve outside the power supply is the same as that of the shielding clothes body, the vest-shaped structure can be worn on the body of an operator, the power supply is positioned on the back of the human body, and the power supply line is led out to be connected to the positioning device at each position after being worn.
The cloth bag is made of the same material as the shielding clothes body, an outer coating layer is arranged outside the power supply line of the positioning device, and the outer coating layer is made of the same material as the shielding clothes body.
The signal antenna of the positioning device sends the position information of the mounting point to the guardian, and the guardian judges the safety distance between the operator wearing the shielding clothes and the electrified body by utilizing the position information.
The positioning principle of the positioning device can adopt an RTK positioning principle, and the RTK positioning device can provide a three-dimensional positioning result of the measuring station in a specified coordinate system in real time and achieve centimeter-level precision. The processor is utilized to receive the position information sent by the positioning device, the real-time position information of the live working personnel is displayed on the three-dimensional model of the power transmission line in cooperation with the three-dimensional model of the power transmission line, the guardian can remotely monitor the real-time safety distance between the working personnel and the live body on the ground or a command center, and when the safety distance is smaller than or equal to the preset safety distance, alarm information is output. The following were used:
and during ground potential operation, calculating the distance between the live working personnel and the live body in real time, and outputting alarm information if the distance is less than or equal to a preset first safety distance.
And during equipotential operation, calculating the distance between the live working personnel and the adjacent phase conductor in real time, and outputting alarm information if the distance is less than or equal to a preset second safety distance.
During equipotential operation, calculating the distance between the live working personnel and the grounding body in real time, and accumulating the distance between the live working personnel and the grounding body to obtain a combined gap; and if the combined gap is smaller than or equal to the third safety distance, outputting alarm information.
The positioning device for sending the position information is installed at the protruding points (head, shoulders, elbows, hands, two sides of buttocks, knees and feet) of the selected shielding clothes in the live working process, the geographical position information of the working personnel can be obtained in real time, the safety distance is monitored in real time, and the safety of the live working personnel is ensured.
The shielding clothes are to carry the positioner of high accuracy, and positioner's precision is centimetre level, in the live working process, will accurately control live working personnel and the distance of charged body and grounding body all around, guarantee that the distance is sufficient, just can guarantee live working personnel's safety. The positions of the head, the elbows, the hands and the feet are the prominent points of the operating personnel in the live working process, the accurate position information of the positions is received through a software system, the points are judged in real time to generate the minimum safety distance, the minimum safety distance is compared with the preset safety distance, and therefore the safety range is always ensured, and warning is given out when the minimum safety distance is smaller than or equal to the preset safety distance.
