Embodiment 1

[0042] Such as figure 1 As shown, the shielding suit for ±1100kV live work is made of wire cloth with electric field shielding effect as the main material, including shielding coverall 1, conductive gloves 3, conductive shoes 4 and conductive socks, and shielding mask 2.

[0043] The above metal wire cloth with electric field shielding effect is a cloth made of stainless steel fiber + tussah silk cotton + metal microfilaments spun and twisted into yarns in a certain proportion. For coveralls, conductive gloves, conductive shoes and conductive socks, the metal content in the metal wire cloth is greater than or equal to 25% (mass percentage). The stainless steel fiber refers to 304, 304L or 316, 316L stainless steel as the base material, which is processed into microfilaments with a diameter of less than 10 μm through the cluster drawing method, and then cut into short stainless steel fibers through the stretch cutting process, and then processed into stainless steel fibers.

Embodiment 2

[0047] Shielding clothing for ±1100kV live work is made of wire cloth with electric field shielding effect as the main material, including shielding coverall 1, conductive gloves 3, conductive shoes 4 and conductive socks, and shielding mask 2.

[0048] The waist of the shielding one-piece suit 1 is provided with an arc suppressing line 5, and the shielding one-piece suit 1 has a cap, and the cap wraps all parts of the human head except the face, and the shielding one-piece suit 1 A conductive tape is provided at the cuff and a trouser leg, a conductive tape is provided at the mouth of the conductive glove, a conductive tape is provided at the mouth of the conductive shoe, and a perspective mirror 6 and a breathing hole are provided on the shielding mask 2 7. The shielding mask 2 is connected to the hat part of the shielding jumpsuit 1 by snap buttons. The shielding jumpsuit 1 has two layers, the outer layer is metal wire cloth, and the inner layer is tussah silk cloth. The c...

Embodiment 3

[0051] Shielding clothing for ±1100kV live work is made of wire cloth with electric field shielding effect as the main material, including shielding coverall 1, conductive gloves 3, conductive shoes 4 and conductive socks, and shielding mask 2.

Abstract

The invention discloses a shielding garment for + / -1100 kV hot-line work. Metal wire cloth with an electric field shielding effect is used as a main material for manufacturing, shielding conjoined clothes, conductive gloves, conductive shoes, conductive socks and shielding masks are included, multiple key tests are conducted in an extra-high voltage direct current test base of the State Grid Corporation of China, and all indexes of test results are higher than those of the national standard GB / T25726-. 2012 'Shielding Garment for 1000 kV alternating-current live-line work' regulations completely meet the safety requirements of live-line work of operators under the normal power transmission condition of + / -1100 kV power transmission circuits, and guarantee the requirement of on-time power transmission of an East China (southern Anhui) + / -1100kV extra-high voltage direct current power transmission project is met.

Description

technical field [0001] The invention belongs to the technical field of ±1100kV ultra-high voltage direct current transmission, and in particular relates to a shielding suit for ±1100kV live work. Background technique [0002] Zhundong-East China (South Anhui) ±1100kV UHV DC transmission project is the world's first ±1100 kV UHV DC transmission line with the highest voltage level, largest capacity, longest distance and most advanced technology. Interconnection, intercontinental interconnection, and the construction of a global energy Internet have opened a new era in the development of UHV power transmission technology. The starting point of the Zhundong-Wannan project is located in Changji Autonomous Prefecture, Xinjiang, and the end point is located in Xuancheng City, Anhui. It passes through 6 provinces (districts) of Xinjiang, Gansu, Ningxia, Shaanxi, Henan, and Anhui. Two converter stations in Zhundong and Anhui will be newly built with a conversion capacity of 2400 10,...
