Xinxiang Power Supply Company: Small Invention Brings Big Security

On November 14th, the author came to Xinzhuang Power Supply Company's 110 kV Wenzhuang transformer station and saw the maintenance personnel wearing a new type of gloves and was smart and convenient when carrying out various tasks. After learning, it was learned that this is a "new type of protective electrical protective gloves."

In the maintenance, inspection and testing of electrical equipment, the working gloves of inspection and testing personnel have always had various problems. The work gloves are cotton and canvas materials. Although they are comfortable to wear, they are precise and wear-resistant. However, due to the high risk of power overhaul and test work, it does not have high temperature resistance, Acid and alkali resistance, antistatic, electrical insulation, etc., and cannot guarantee the personal safety of workers. In particular, when one or two parts of the power outage equipment are disconnected and tested, the hand will inevitably touch the metal object, and will still suffer an inductive attack, resulting in falling from a height. The insulating gloves used for live working are made of natural rubber, which has the advantages of protection against electricity, water, acid and alkali, and oil, and plays a protective role to the human body. However, its volume, thickness, and hardness are large, and the finger cannot be flexibly bent when used, and the gripped object is inaccurate, resulting in low work efficiency.

In view of the above two situations, the induction electrical protection gloves developed by the Transformer Maintenance Department of Xinxiang Power Supply Company fully take into consideration the respective advantages of cotton spinning, canvas material work gloves and rubber insulating gloves, and fuse the two together. Using cotton, canvas - soft copper mesh - cotton, canvas three-tier structure, in the glove port with a copper box, 6 meters of copper wire, and the glove is connected to the copper wire mesh, copper wire will be pulled Grounded. In the event of an "inductive power," induced currents will flow through the copper wire mesh and will no longer pass through the human body and be protected from inductive power. The inductive electric protective gloves are applicable to the ground, ladders and engineering vehicles.

The seemingly safe substation outage maintenance and testing work actually has a high safety risk. The successful development of "new-type induction electric protective gloves" ensures the personal safety of on-site inspection and test personnel, while improving work efficiency, shortening the time of power outage, and achieving the safety, high-quality and high-efficiency of power production.

"The new type of induction electrical protection gloves" has obvious effect in practical work and has been officially reported to the State Patent Office.
