The design of the gas-filled cabinet provides two options for the protection of the transformer: load switch-fuse combination and circuit breaker with relay protection. As the preferred ring network unit, the gas-filled cabinet can provide a complete set of integrated remote control and monitoring units. The ring network cabinet adopts standardized components such as load switches, SF6 or vacuum circuit breakers, earthing switches, transformers and secondary components. Through the combination of these standardized components, the ring main unit can be widely used in different occasions.

(1) The shell of the inflatable cabinet is welded into a completely airtight structure, which excludes the influence of environmental factors. The insulating strength of SF6 gas is 2. times that of air, thus obtaining the advantage of saving space, reducing the building area, and achieving good economic benefits. (2) Using laser welding technology to prevent SF6 insulating gas from escaping and moisture intrusion. This laser welded gas-filled cabinet meets the requirements of IEC60698 and VDE0670 part 1000 for airtight pressure systems.

Wanshang Power introduces you to the basic knowledge of complete sets of equipment
1. What is a complete set of equipment? A complete set of equipment refers to an industrial combination device that produces finished or semi-finished products. It can be a workshop, a production line, a workshop or a factory. It can be a single item of equipment of a profession, or it can be a comprehensive equipment of several professions. Since the inspection procedures and specific practices of imported complete sets of equipment and export complete sets of equipment are different, they are introduced separately. 2. Wanshang Power tells you what is a complete set of power equipment? The complete power distribution unit is made of

Temperature rise and structural characteristics of box transformers
A box-type substation is a prefabricated, compact electrical equipment that assembles high-voltage switchgear, distribution transformers and low-voltage electrical devices according to a certain wiring method. With the development of economy and the acceleration of urbanization, box-type substations like this one have the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, less investment, quick effect, and short power transmission cycle. It is widely used in urban and rural power grids. Especially due to urban planning, land

What should be paid attention to in the installation of box-type substations
The correct installation of the box-type transformer is the key to the correct use of the equipment in the subsequent process. Following the operation instructions can avoid vague failures due to improper installation during use, and reduce the frequency of downtime for maintenance. 1. The box transformer is mainly composed of natural wind and circulating cooling. Therefore, there should be no illegal stacking around it, especially the transformer room door should not be blocked, and the shutters should be regularly removed for ventilation and the attachments on the sub-holes to ensure that all electrical equipment does not exceed the allowable temperature. 2. Box type changer
