TECHNICAL FIELD
[0001] The utility model relates to the technical field of static electricity prevention, specifically, relates to a static electricity prevention bracelet for relay protection equipment inspection. BACKGROUND
[0002] Relay protection devices play a crucial role in power systems. Their main purpose is to detect and isolate faulted sections in a timely manner when a fault occurs, thereby protecting the safe and stable operation of the power system. Regular annual inspection is essential to promptly identify and eliminate potential safety hazards. With the development of annual inspection of relay protection devices, the problem of static electricity has gradually become prominent. Static electricity is a static state of charge accumulation, which may come from the process of friction, contact separation, etc. in the environment. When static electricity accumulates to a certain extent, it will produce discharge phenomenon and release a large amount of energy. Static electricity may cause potential harm to relay protection devices, and static discharge may cause its contact to stick together, burn out or performance degradation, thereby affecting the normal on-off of the circuit. In addition, static electricity may also interfere with the internal circuit of the relay protection device, causing signal transmission errors or functional failure, affecting its normal work, and even causing the failure of the entire circuit system. Therefore, the static electricity protection of relay protection devices has become an important part of the safe and stable operation of the circuit.
[0003] 1. Increased cost: In order to prevent the influence of static electricity on relay protection devices, special wire clamp equipment may be required, which is an integral structure and needs to be replaced if damaged, which will increase the cost of the equipment;
[0004] 2. Easy to lose: Traditional grounding clamps usually need to be carried, and there is no special fixing point and hook, which is easy to be forgotten after being placed in a certain place, or to fall off or be damaged during movement, bringing great inconvenience to the user;
[0005] 3. Static electricity accumulation problem: The main function of the grounding clamp is to quickly guide static electricity to the ground through the grounding system to avoid static electricity accumulation on the equipment and cause damage. However, the grounding clamp is a clamp, which may cause poor grounding effect and may cause static electricity accumulation, thereby affecting the normal operation and safety of the equipment.
[0006] 4. Limited operation space: Grounding clamps are usually made of hard metal materials, which have high strength but fixed structure and cannot be adjusted flexibly. Moreover, the clamp needs to be clamped manually and is easy to fall off, which requires special attention during use, which may affect the flexibility and work efficiency of the operator, and may also fall off or move due to activity, affecting the static electricity protection effect.
[0007] 5. Uncomfortable to wear: the rubber band design is unreasonable, and it cannot be adjusted according to different wrist sizes, resulting in tight or loose wearing. Moreover, the material of the rubber band may not be soft or breathable enough, and long-term wearing can cause skin discomfort or allergy. Utility model content
[0008] The utility model discloses just based on above technical problem, propose a kind of for the anti-static bracelet of relay protection equipment inspection.
[0009] A kind of for the anti-static bracelet of relay protection equipment inspection, bracelet is by watchband, buckle the wearable equipment of loose and tight, watchband is woven from conductive material and ordinary material, inner layer is conductive yarn, can effectively contact with skin and conduct static electricity, outer layer is ordinary yarn, improve the comfort and durability of wearing.Buckle upper side is equipped with conductive interface, and conductive interface is electrically connected with wire yarn, ensure that the transmission passage of static electricity is unobstructed.
[0010] One end of connecting line is connected with conductive interface, and its other end is equipped with plug, and plug is inserted on the grounding plug of grounding equipment, realizes the release of static electricity.
[0011] As further improvement of the application, one end of watchband is connected and fixed with one end of buckle, the other end of watchband is inserted from the other end of buckle and is inserted from the opening on the upper side of buckle, and the hinge buckle is provided on the left side of the opening, and the buckle can be pressed tightly to facilitate the adjustment of the tightness of the watchband.
[0012] One end of connecting line is equipped with movable snap, and movable snap is detachably rotatably connected with conductive interface, to facilitate wearing and storage of bracelet.
[0013] Connecting line is PU spring wire, with good stretchability and flexibility, convenient for operator to move.
[0014] Grounding equipment is also provided with placing seat, and bracelet can be tightly placed on placing seat, to facilitate storage and management of bracelet.
[0015] Beneficial effects:
[0016] 1. More direct grounding: bracelet is usually directly worn on wrist, and is connected to grounding plug through a conductive connecting line and plug. This design not only is not easy to fall off, but also makes static electricity release more directly and quickly, reducing the risk of static electricity accumulation.
[0017] 2. More cost-saving: bracelet adopts modular design, and multiple components can be independently detached and replaced. This design not only improves the convenience of maintenance, but also enables individual replacement when a component is damaged, avoiding the abandonment of the entire device and saving costs.
[0018] 3. Better human adaptability: the anti-static bracelet is designed to fit the human wrist better, more in line with the ergonomic principle, and will not feel uncomfortable even after a long time of wearing, nor will it affect the normal work of the operator;
[0019] 4. Larger operating space: the anti-static bracelet jack has an anti-loose design to ensure that the bracelet is not easily detached after insertion, and the hole can be set up with multiple, so that the operator can move the bracelet grounding position as needed during operation, thereby expanding the operating space;
[0020] 5. More convenient to use: the anti-static bracelet has a dedicated placement seat, just like the grounding jack, the placement seat can be designed inside the switch cabinet to ensure that the bracelet has a clear placement point when not in use, avoiding clutter, making it easier to take and use the bracelet;
[0021] 6. Higher safety: the anti-static bracelet design takes into account human contact, even if accidentally touching the power supply during operation, its resistance value is within the safe range, which can protect the user from electric shock. The traditional wire clip does not have such a design, and if misused or improperly used, there may be safety hazards. In addition, the dedicated jack can also place the bracelet accidentally connected to the live body.
[0022] 7. More easily standardized: the anti-static bracelet is easy to achieve a unified standard, facilitating communication and cooperation between different enterprises and institutions, while the traditional wire clip has various forms and is difficult to standardize.
