It shall be used in accordance with the requirements of "Electric Power Safety Work Regulations" and "Regulations on the Administration of Safety Instruments of State Grid Corporation", that is to say, "correctly use electric power safety instruments".
Power safety instruments are divided into four categories: personal protective equipment, insulation safety instruments, climbing instruments, safety fences (nets) and signs.
Personal protective equipment refers to the safety appliances used to protect the human body from acute injury, including safety helmet, protective glasses, self-priming filter gas mask, positive pressure fire air respirator, safety belt, safety rope, connector, speed difference automatic controller, self-locking device of guide rail, buffer, safety net, electrostatic protective clothing, anti-arc clothing, acid-proof clothing, SF6 protective clothing, acid-proof gloves, acid-proof boots and conductive shoes (anti-static shoes).
1. Safety helmet can protect the head from falling objects and other specific factors. It consists of a cap shell, a cap liner, a chin strap and accessories.
2. Protective glasses are protective appliances to protect workers from arc burns and prevent foreign objects from falling into their eyes when carrying out maintenance work and maintaining electrical equipment.
3. Self-priming filter gas mask is a respirator used in aerobic environment.
4. Positive pressure fire fighting air respirator is a kind of respirator used in anaerobic environment.
5. Seat belts are personal protective equipment to prevent workers from falling or hanging safely after falling. Generally, it is divided into safety belts for climbing operation, safety belts for area restriction and safety belts for falling suspension.
(1) The working safety belt around the pole is a safety belt that binds the human body near the fixed structure with a rope or a belt, so that the operator can perform other operations with both hands.
(2) Area restraint seat belts are used to limit the range of activities of workers and prevent them from reaching the area where falling may occur.
(3) Falling suspension seat belt refers to the seat belt used to safely suspend the operators when working at high altitude or climbers fall.
6. Safety ropes are ropes (belts, steel ropes, etc.). ) Connect the safety belt tie and suspension point, which are generally divided into safety rope for fence operation, safety rope for area restriction and safety rope for falling suspension.
7. The connector can connect two or more parts together, and it is an annular part with a normally closed valve.
8. The automatic speed difference controller is a device installed on the hanging point, equipped with a retractable rope (belt, wire rope), which is connected in series between the seat belt and the hanging point, and has a braking effect due to speed change when falling.
9. The guide rail self-locking device is attached to the rigid or flexible guide rail, which can slide along the guide rail with the user's movement and cause braking due to falling action.
10. The bumper is a device connected in series between the seat belt and the hanging point to absorb part of the impact energy and reduce the impact force when falling.
1 1. Safety nets are used to prevent people and things from falling, or to avoid or reduce injuries caused by falling and object impact. Safety net generally consists of net body, side rope and tether. Safety net can be divided into flat net, vertical net and dense mesh safety vertical net.
12. Electrostatic protective clothing is a kind of clothing made of conductive materials and textile fibers, which is used to protect the patrol of lines and substations and the ground potential workers from the influence of AC high-voltage electric fields.
13. Anti-arc suit is a kind of protective suit made of insulation and protective interlayer to protect the wearer's body, which is used to reduce or avoid the damage caused by a large amount of thermal energy radiation and splashing melt when arc occurs.
14. Acid-proof clothing is a kind of work clothes with acid-proof performance, which is suitable for workers engaged in contact and preparation of acid substances. Made of acid-resistant fabric or rubber, plastic and other acid-resistant fabrics. Acid-proof clothing can be divided into breathable acid-proof clothing and airtight acid-proof clothing according to the properties of materials.
15.SF6 protective clothing is to protect the personal safety of personnel engaged in the installation, commissioning, operation and maintenance, testing and overhaul of SF6 electrical equipment at the site, and to prevent operators from being hurt by toxic and harmful substances such as hydrofluoric acid, sulfur dioxide and low fluorine. SF6 protective clothing includes one-piece protective clothing, SF6 special gas mask, SF6 special gas cylinder, work gloves and work shoes.
16. Acid-resistant gloves are protective gloves to prevent acid and alkali from hurting hands.
17. Acid-resistant boots are shoes made of waterproof leather, plastic and rubber. , with molded, vulcanized or injection molded acid-resistant soles, with acid-resistant performance, suitable for protecting feet from injury when they are splashed with acidic solutions.
18. Conductive shoes (anti-static shoes) are made of rubber with special properties, and wear in the area of (220 ~ 500) kV pole towers and (330 ~ 500) kV live equipment to prevent electrostatic induction voltage.
