Abstract: Safety production is an eternal theme for electric power enterprises. The management of safety equipment is an important part of daily operation and maintenance management of substations. The quality of safety equipment will directly affect electric power enterprises. Personal and equipment safety during production. In the past few years, personal casualties and equipment accidents have occurred in various units due to safety equipment problems. Since safety equipment contains a wide variety of equipment and a large quantity, its management involves type, quantity, inspection and testing, scrapping and updating. In many aspects, this article aims at problems in management and proposes measures to solve the management of safety tools, in order to provide theoretical support and reference for the management of safety tools.

1. Major problems in the management of safety equipment

1.1 The awareness of regular testing of safety equipment is relatively weak

"Safety Work Regulations in the Electrical Industry" The test cycle for various safety equipment is clearly stipulated in it. Some workers on the production line believe that the testing of safety equipment is not good and will cause mechanical damage. Some grassroots leaders believe that the testing of safety equipment has little impact on safe production and believe that it will increase production costs and increase the time required for testing. The work brings a lot of inconvenience, so the testing of safety equipment is not regarded as a safety work, resulting in the phenomenon that untested or over-cycled safety equipment is still in use.

1.2 The monthly appearance inspection is just a formality

The "Electrical Industry Safety Work Regulations" also stipulates that climbing and lifting equipment should be inspected once a month. At present, most units have not done this work well. For example, the safety belt buckle has fallen off and is still being used. Some lifting equipment, such as pulleys and cable clamps that have been deformed due to external damage or have screws missing, are still in use on site, which brings unsafe factors to production.

1.3 There are problems in the selection and procurement of safety tools

During the selection and procurement, on the one hand, the purchasing personnel lack knowledge of the performance and usage of the tools. Understand that there will be some unreasonableness in the specifications and forms of the selected safety tools, which will cause inconvenience to the workers on the front line of production. The ordering personnel of some units regard ordinary rain boots and miner boots as insulating boots. If they are used, the consequences will be disastrous. On the other hand, due to the existence of human relations, some "three no's" products and fake and shoddy products continue to flow into some production units of the power system.

1.4 Irregular use of safety tools and lack of care and maintenance

According to national inspection data statistics, it is found that about 40% of unqualified tools are caused by human damage or mechanical damage. of. In particular, it is common for line safety equipment to be thrown directly downwards from the pole (tower) without using a transfer rope. Some production units have little awareness of the care and maintenance of safety equipment.

1.5 - The configuration of safety equipment in some units is unreasonable

The configuration of safety equipment should not be generalized and should be reported to each power supply station (substation) and power supply business office ( Agricultural power stations) equipment jurisdiction, the number of staff and other specific circumstances should be comprehensively considered, and the specifications and quantities of working tools should be reasonably allocated. Excessive quantities will cause economic waste, and insufficient quantities or uneven specifications will directly affect safety. Production.

2 Strengthen the management measures of safety equipment 2.1 Classification of safety equipment

Basic insulating safety equipment includes capacitive electroscopes, insulating rods, insulating partitions, and insulating covers. , portable short-circuit grounding wire, personal security wire, phase nuclear device, etc. Auxiliary insulation safety equipment includes insulating gloves, insulating boots (shoes), insulating rubber pads, etc.

General protective safety equipment includes safety equipment. Hat, safety belt, ladder, safety rope, foot buckle, anti-static clothing (static induction protective clothing), anti-arc clothing, conductive shoes (anti-static shoes), safety self-locking device, speed difference automatic controller, protective glasses, filter-type anti-virus Masks, positive pressure fire respirators, SF6 gas leak detectors, oxygen testers, acid and alkali resistant gloves, acid resistant clothing and acid resistant boots, etc. Safety signs include various safety warning signs, equipment signs, etc. The equipment is equipped with various related safety tools.

2. 2 Standardized configurations

At present, there are different manufacturers and models of safety tools, such as electroscopes and insulating rods. There are two sections, some have three sections, and the manufacturers and models of the safety tool cabinets are also different, so some safety tools cannot be placed in the tool cabinets. Through standardization, the size, testing and numbering of the safety tools can be unified. The position of the labels is consistent, which greatly facilitates the management and use of safety equipment. Secondly, new stations should be built according to standards, and safety equipment that fails the annual test and is damaged should be replaced according to standards. The surrounding environment should be clean and dry, and safety equipment should be easily accessible. Floors, walls, and ceilings should be made of fireproof and dust-free materials. Safety equipment cabinets should have automatic temperature and humidity control functions and meet the requirements of beautiful appearance. .

The safety equipment room should be kept ventilated and dry, the relative humidity in the room should not be higher than 70%, and the indoor temperature should be maintained in the range of 15-35 degrees Celsius. When ventilating indoors, it must be done in dry weather, and the relative humidity outside should not be higher than 75%. After ventilation, the relative humidity in the room should be checked immediately and controlled.

2.3 Standardized management

In the management of substation safety tools, vigorously promote standardized management. Standardize the different standards of various safety equipment in substations, so that the equipment numbers are obvious and clear. The voltage level and test date signs of electroscopes, insulating rods, and insulated safety equipment should be intact and qualified. Carry out standardized management of safety equipment and standardize the placement of safety equipment so that safety equipment has a fixed storage place and should be stored in a clean and dry place to prevent moisture and condensation. Standardize the management of various signboards to ensure that the specifications of various signboards comply with the requirements of safety regulations, and ensure that the types are complete and stored in an orderly manner. At the same time, human resources carry out standardized inspections of substation safety tools and equipment, and formulate operation books and inspection cards to achieve There are standards for inspections and basis for inspection and maintenance to ensure the quality of inspections and maintenance. For tools and equipment that are found to be damaged or have safety hazards, stop using them and purchase replacements as soon as possible. Ensure that various safety equipment are tested according to the prescribed cycle and used after passing the test. They cannot be used beyond the specified period to ensure personal safety.

24 Improving Management Concept

Nowadays, the number of substations, especially unmanned stations, is increasing. Although more and more safety tools are equipped, the test process of tools and tools is complicated, and the operation and maintenance personnel But the quantity is limited. The original management model is difficult to adapt to new changes, and the intensification of substation safety equipment management has become a development trend. Nowadays, there are more and more smart substations and digital substations, and there are more and more trolley switches and closed combination electrical appliances. The number of safety instruments configured in the substation will be appropriately reduced if the requirements are met. New standards and specifications must constantly adapt to technological developments. In order to continuously adapt to the development of technology, electric power companies have developed new tools and tools based on continuous accumulation and summary of experience. For example, in terms of safety tool management, they have developed vehicle-mounted safety tools, which has greatly reduced the number of tools and tools in substations. , reduces costs, improves efficiency, and also lays a solid foundation for safe production.

3 Conclusion

In short, substation safety tools are important tools to ensure personal safety. Through the standardization and standardized management of safety equipment and the continuous application of new technologies and new models, production costs should be continuously reduced, the workload of staff should be reduced, work efficiency should be improved, and the foundation for safe production should be laid.
