Switch cabinet is divided into high voltage switch cabinet equipment and low voltage. High voltage has ring network cabinet, middle cabinet, G G 1 A, etc. There are also many kinds of ring network cabinets. The so-called "ring network cabinet" of the ring network cabinet means that each distribution branch is equipped with a switch cabinet (outgoing switch cabinet), and the bus of this switch cabinet is also a part of the ring trunk line. That is to say, the ring trunk line is composed of the busbars of each outgoing cabinet connected together. Each outgoing cabinet is called "ring network cabinet". In fact, it is impossible to see the meaning of "ring network" by taking out a ring network cabinet alone. These ring network cabinets are not large, so the high-voltage switch of the ring network cabinet generally does not use a circuit breaker with a complex structure and adopts a high-voltage load switch with a high-voltage fuse with a simple structure. In other words, the high-voltage switch in the ring network cabinet is generally a load switch. The ring main cabinet uses the load switch to operate the normal current, and uses the fuse to cut off the short-circuit current, which combines to replace the circuit breaker. Of course, this can only be limited to a certain capacity. Such a switch cabinet can also be used in the distribution system of non-ring network structure, so with the wide application of this switch cabinet, "ring network cabinet" jumped out of the category of ring network power distribution and generally refers to the high-voltage switch cabinet with load switch as the main switch.

 

1. refers to different

 

1. Ring network cabinet: it is a group of electrical equipment for power transmission and distribution (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit.

 

2, high voltage switchgear equipment: used in power system power generation, transmission, distribution, power conversion and consumption in the on-off, control or protection of equipment.

 

2. characteristics are different

 

1. Ring network cabinet: the core part adopts load switch and fuse, which has the advantages of simple structure, small size, low cost, can improve power supply parameters and performance, and power supply.

 

2. High-voltage switch cabinet: it has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines, bus connection, etc.

 

3. uses differently

 

1. Ring network cabinet: It is widely used in urban residential quarters, high-rise buildings, large public buildings, factories and enterprises and other load distribution power stations and box-type substations.

 

2. High-voltage switchgear: It should be suitable for various places such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mining enterprises, residential communities, and high-rise buildings.
