Sichuan sales of intelligent dehumidification safety tool cabinet

In the domestic power industry, insulated tools are widely used for live work or operations, and for maintenance and repair of power equipment. The insulation performance of insulated tools decreases after being affected by moisture, strictly endangering the life and safety of maintenance personnel. It is necessary to ensure that insulated tools are clean and dry, and store them reasonably. The existing measure is to use wooden or iron cabinets or insulated tool storage rooms to store or keep insulated tools. Wooden and iron tool cabinets do not have long-term and constant moisture-proof effects and are extremely susceptible to moisture. However, this kind of warehouse investment Large, high energy consumption, slow drying process, especially for units with few insulated tools, there is no need to build an insulated tool warehouse. Therefore, the design of intelligent safety tool cabinets can effectively solve the above problems, help electric workers store insulated tools well, ensure that insulated tools will not get damp, and no dangerous problems will occur when electric workers use them, ensuring the safety of workers. Safety tool cabinets can be widely used in power units and departments such as substations, centralized control stations, line work areas, and power company customer service centers with voltage levels, and can be used in environments with different conditions and temperatures.
The safety tool cabinet is a mechanical switch device used to ground the circuit. Under abnormal conditions (such as short circuit), it can carry short-circuit current for a specified time, but under normal circuit conditions, it is not required to carry current. Safety tool cabinets need to adopt certain principles and methods for actual use, be well implemented in certain methods and principles, and be able to be used according to the information and principles in the market. This is the main difference between grounding switches and safety tool cabinets. In actual operation, the following procedures must be strictly followed: when the safety tool cabinet is closed, the grounding switch must be opened. After the safety tool cabinet is opened, the grounding switch can be closed. This means that the grounding switch has no possibility of passing operating current for a long time, so the grounding switch does not have parameters for rated current and loop resistance.
Safety tool cabinets are usually selected based on the rated short-time withstand current rather than the rated current, so the maximum long-term current passing through the safety tool cabinet is much smaller than the rated current, and considering long-term development, generally select The rated current also has a large margin. Therefore, the reason for the heating of the conductive circuit of the safety tool cabinet during operation is not that the passing current is too large and exceeds the rated current, but is caused by problems with the structure, material, surface treatment and assembly process of the contacts and contact parts, as well as the harsh operating environment. The contact resistance of the contact parts increases, causing overheating and a vicious cycle. To solve the overheating of the conductive circuit of the outdoor isolating switch, the key is to prevent the occurrence of poor contact. This requires comprehensive consideration from improving the structural design, selecting high-quality materials and improving the manufacturing process level, including improving the quality of installation and adjustment, improving operating conditions and maintenance Maintenance work to improve the product's ability to withstand environmental impacts. according to. After a temperature rise test with twice the rated current, the conductive circuit still overheated, indicating that increasing the temperature rise test current does not mean that the isolating switch has overload capability. This should be paid attention to when selecting an isolating switch.
When the height of the safety tool cabinet is increased, its creepage distance will naturally increase accordingly. However, this increase in creepage distance is an indirect result of the increase in dry arc distance and is not corrected by the altitude coefficient. Theoretically, the creepage distance of a safety tool cabinet is not directly related to the altitude. However, the dry arc distance of the safety tool cabinet is related to the altitude. The dry arc distance of isolating switches used in areas above altitude should be corrected according to the altitude correction coefficient. Since the dry arc distance of insulators in high altitude areas is corrected according to altitude, in order to meet the requirements, the height of the insulator must be increased.
The safety tool cabinet is equipped with four universal wheels and positioning screws at the bottom. Four hanging cups are installed on the top of the cabinet to facilitate transportation. The safety tool cabinet can be used in different places, and can also be used conveniently for transportation, making it convenient for users to use.
