Here comes, many electrical novices don’t know how to supply power to the solid insulated ring main unit. The editor has compiled some today to share with you. Look good, I hope it will be helpful to you.

    1. The solid insulated ring main unit is generally not used by terminal equipment power engineering users. Because the key function of the solid insulated ring main unit depends on the acceptance and distribution of electromagnetic energy, the function is the "open" and "close" of the route of human factors. , There are very few automatic breaking; the machinery and equipment of the solid insulation ring main unit are mostly ring main units. The general ring main unit is not set for maintenance. In order to reduce the volume of the high-voltage switchgear, it is installed more internally. It is a high-voltage load switch, not an isolating switch.

    In other words, most of the machinery and equipment inside the switching site can break the load current, but not the short-circuit capacity; it is the fundamental difference between the switching station and the power distribution station, and it is not possible to bring the maintained equipment without maintenance, such as Therefore, switching stations are often used in power supply companies, not in user terminal equipment stations. Therefore, it is unlikely that there will be regulations for users in my country to build switching stations;

    2. From the above indication, it can also be seen that the solid insulated ring network cabinet can be a single switching power supply, or it may be a dual (multiple) switching power supply to develop dual circuits. This must be based on actual requirements. If the user's load is very critical, It is necessary to have dual power switches, and the economic development can afford to pay, you can introduce dual power switches, otherwise there is no need to introduce dual power switches; for power supply companies, in order to better improve the credibility of power supply, often implement more Switching power supply dual-loop power supply method, it is common to introduce several switching power supplies into one power supply point, so users do not have to compare with the power supply company;

    3. There are many ways to improve the credibility of power supply. In the past, the credibility of power supply was low, mostly due to large vacancies in power projects and power cuts. Now the credibility of the power supply system has improved, and the level of operation and maintenance has been improved. It has also been improved. The biggest problem is the safety of the user’s internal machinery and equipment. For many years, the practice is that when users have problems, most of them are not available for electricity, and how many switching power supplies are useless. Therefore, I suggest that users, no It is necessary to build so many switching power supplies and spend so much money. Switching power all the way is reliable and sufficient. Spend the money on the necessary machinery and equipment. In addition, prepare non-electrical security personnel countermeasures.
