SRM16-12 box type gas filled cabinet, fully insulated ring network cabinet
SRM16-12 fully insulated, totally enclosed, co box type gas filled cabinet, armored metal enclosed structure, shell steel, CNC Machine tool Processing, and double folding technology, the outer surface is coated by the process, the whole cabinet is characterized by high precision and corrosion resistance.
Assembly type. The upper part is an isolation chamber equipped with electric meters, and the middle part is equipped with a circuit breaker to isolate switch , earthing switch and Wire and cable System. If the installed arrester changes Box Thickness of lightning rod Cable System. The main buses and voltage transformers are installed at the lower part of the box, and the above insulated bushing current transformers are installed in the imported and cable TV systems. The box unit shall arrange the combination according to law.
Switch the use of solid insulating materials for live parts of all elements, do not touch live parts, shield grounding, and use safely.
It mainly includes incoming cabinet, export cabinet, cabinet contact and measurement cabinet. According to the arrangement of user needs, the combination can form a variety of distribution systems.
A rectangular insulation pipe is provided in the middle of the cabinet, and the insulation pipe provides vacuum switch, disconnector, grounding switch and bus base.
All live parts are contained in an insulated oil cylinder. Men are not moved. Therefore, the safety of operators. Insulating oil cylinder provides spring energy storage operation mechanism (permanent magnet mechanism) and manual operation mechanism of disconnector. The cable entry and exit system is located in the middle of the center.
The cable is installed in the front of the box, which is convenient for users to install and use.
The next line of the system and the contact bus at the box cable outlet are closed for the safety of the operator.
The insulated square cylinder at each stage is provided with a transparent observation window through which the switching position of the individual grounding switch can be seen. Let the operator observe the operation status of the switch cabinet.
Since the structures of different gas filled cabinets are different, the power supply network is also different The application programs are different because of the different reliability of the structural changes of the American inflatable cabinet and the European box. When the box transformer capacity in the United States is small and the residential building area is large, the application of box variables will increase a lot, so the overhead line connection load will increase; When reducing overhead lines connected to load points, the serial number must be increased so that the network structure is weak. The network structure to overcome this problem is a small box of this capability, which can better solve this problem. 1. American inflatable cabinet changed its application The structural features and advantages and disadvantages of the American box are that the American box is applied to multi-storey residential buildings and other important buildings with relatively low power requirements. According to our actual use, the United States and a small ring network switch box are completely suitable for the power supply required by multi-storey residential buildings. Because in the case of failure, the impact is small, but it is not suitable for small high-level and high-level. |
