Description
Technical Field
The utility model relates to a live working shielding clothes.
Background
When a human body enters a strong electric field and approaches a charged body, the charged body discharges electricity to the human body, and potential differences and the like are generated at all parts of the human body in the strong electric field. Although a human body has resistance, the resistance value is small and is negligible compared with the insulation resistance of an insulation ladder or air used for live working, and the resistance value can be regarded as a conductor. When the operator climbs the insulating ladder to contact the charged body for equipotential operation, the human body gradually increases the earth potential and the potential between the human body and the charged body gradually decreases as the human body and the charged body gradually approach each other. According to the principle of electrostatic induction, the charges on the human body are redistributed, i.e. one end close to the high-voltage charged body presents charges with different polarities. When the high-voltage charged body is close to the high-voltage charged body, the induction field intensity is large enough to make the air be ionized and broken down, and then the charged body starts to discharge to the human body. When the operator holds the charged body with hand, the charge neutralization discharge is finished and the induced charge disappears completely. At this time, the human body is at the same potential as the charged body, and the human body potential is in a stable state. However, capacitance exists between the human body and the ground and between the human body and the adjacent phase conductor, so that capacitance current still flows through the human body, but the current is very small, and the human body generally has no feeling;
in addition, when the human body is in a high-voltage electric field, although the human body is insulated from the ground, due to the equivalent capacitance effect of the human body, all parts of the human body are not completely in an equipotential state, and the potential difference between all parts is different. When a human body excessively enters a strong electric field along an insulation ladder (or an insulator string) from the ground potential, large potential variation and potential difference 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.
The washing and maintenance of the electromagnetic shielding clothes are divided into the following aspects:
1. the electromagnetic shielding clothing should be stored in a ventilated and dry place as much as possible.
2. The electromagnetic shielding clothes are hung as much as possible when not worn so as to prevent the functional fibers from being broken.
3. The electromagnetic shielding clothing should not be placed with other chemicals.
4. Electromagnetic shielding garments of metal and silver fibers are washable (metallized fabrics do not recommend laundering).
5. The electromagnetic shielding clothes can not be bleached when being washed, or washing products containing bleaching components are used; to follow the second of these, live-working shields are now hung when not worn (to avoid folding the clothing to break the wires within the shield), but even then there may be functional fiber breakage (especially functional fibers in the shoulders of the shield are more likely to break due to the hanging load of the clothes hanger and hanging) or stretching.
The live working shielding clothes are used and noted as follows:
(1) the appearance quality must be carefully checked before use and cannot be used if damaged.
(2) When the shielding clothes are worn, the multi-strand metal connecting wires of various parts such as clothes, caps, gloves, socks, shoes and the like are connected according to a specified sequence and cannot be in direct contact with skin, and the shielding clothes are internally worn with underwear.
(3) When the equipotential operation is carried out, the short circuit of grounding current, the capacitance current of a no-load circuit and a coupling capacitor through a shielding clothes is strictly forbidden according to the regulations of electric industry safety work regulations.
(4) After the shielding clothes are used, the shielding clothes must be kept properly and do not contact with moisture and pollutants so as to avoid damage and influence on electrical performance.
In order to comply with item (2), an operator who carries out live overhaul work on a power transmission line or a converter station often needs to wear a live working shielding garment after matching a piece of comfortable underwear in advance, which is very inconvenient.
