With the changes of the times and rapid social development, the use of low-voltage power distribution cabinets has become more and more extensive. Today, such products have become people's daily infrastructure. Since low-voltage power distribution cabinets have been used frequently in industries and other fields, it is the most basic equipment for power consumption in various factories. Nowadays, different groups pay close attention to the technical requirements of the low-voltage distribution cabinet and the precautions during operation. Let us briefly understand the technical requirements of the low-voltage distribution cabinet and the basic precautions during the operation.
Low voltage distribution cabinet model
There are many types of low-voltage distribution cabinets, and generally different manufacturers have their own models. Domestic models are MLS, GCS, GCK GGD, etc.; foreign manufacturers ABB are: MD190, MNS, ArTu, Blokset, 8PT and so on. The general standard model is GB7251.1
First place: P-open low-voltage switchgear, G-closed low-voltage switchgear
Second place: G-fixed, C-extracted, H-fixed, and mixed-loaded.
Third place: L (or D)-power, K-control, S-senyuan electrical system
GGD is cheaper, and GCS and GCK are economical.
Low-voltage distribution cabinet price
The specific price has not been determined, mainly based on several aspects to confirm, what are the components, what is the component brand, and the price of low-voltage distribution cabinets is about a few thousand. This is relatively cheap, we should find a good price, good quality manufacturers are right.
Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!

Low voltage distribution cabinet technical requirements
Secondly, the secondary windings of current transformers, which are usually related to voltage transformers and equipment, should be permanently protected and ensure safety and reliability.
Thirdly, when the low-voltage power distribution cabinet is in operation, the secondary circuit of the current transformer in the relevant equipment is in the process of being operated, and it is necessary to take effective safety measures.
Fourth, in addition to the need for safety measures when the current transformers are operated in the secondary loop, the related voltage transformers also need to take effective safety measures when the secondary loops work to further ensure the safety of the system.
Fifth, the relevant staff should carry out maintenance and nursing on a regular basis. The technical requirements for such low-voltage distribution cabinets are the most basic. It can prevent short circuit phenomenon in the facility and ensure safe and reliable grounding.
Sixth, when any staff member operates a low-voltage power distribution cabinet, he should wear professional insulated gloves according to the technical requirements of the relevant low-voltage distribution cabinet. And when necessary, be sure to stop the operation of the relevant relay protection device before proceeding.
Seventh, for the operation and use of the facility, it must be periodically tested whether the relevant current and voltage are in compliance with the prescribed standards.
Eighth, before testing for current and voltage, we must inform relevant staff to conduct on-site inspections and confirm that there are no problems before testing of the equipment can begin.
Development status
1: low-voltage switchgear and control equipment commonly known as low-voltage switchgear, also known as low-voltage power distribution cabinet, it refers to AC and DC voltage below 1000V complete sets of electrical devices.
2: China's low-voltage distribution cabinet market has maintained rapid growth with the implementation of smart grids, infrastructure construction, manufacturing investment, and new energy industry development.
3: Monitoring data show that in 2010, the total sales volume of China's low-voltage switchgear market was 10.633 billion yuan, an increase of 11.2% year-on-year; in 2011, the total sales volume of China's low-voltage power distribution cabinet reached 11.960 billion yuan, an increase of 12.5% ​​year-on-year.
4: Under the favorable market demand for low-voltage power distribution cabinets in China, the internal competition in the industry will inevitably intensify. Providers of the new generation of low-voltage complete sets of equipment and system solutions will gain the upper hand in the future market competition. With these characteristics, we can win certain advantages in the future competition and thus seize the commanding heights of the fourth-generation low-voltage electrical products.
Editor's summary: As more and more people in the field begin to widely use products such as low-voltage power distribution cabinets, information on the technical requirements of low-voltage power distribution cabinets has also received more attention from the group. Low-voltage power distribution cabinets belong to electrical equipment and must be manufactured, installed, and used in strict accordance with national standards or requirements. Only in this way can the dangers caused by quality problems or improper use be avoided.
