The circuit breaker is an outdoor small magnetic column structure. It is equipped with a C spring operating mechanism to connect and install with the body. It is simple to install, easy to debug, and reliable in action. It is suitable for frequent operation of the mechanism for more than a few times in its life. The compressed air arc extinguishing structure has extremely strong breaking capacity, with a cumulative number of breaks, creating the most reliable sealing performance in the country. Imported sealing gaskets are used, and the dynamic seal adopts a type sealing ring with a spring pressure compensation structure. The transformer secondary wiring board is matched by a cooperative enterprise to ensure an annual air leakage rate of &%. The included current transformer is made of microcrystalline alloy with high magnetic permeability. Materials, the accuracy can reach . or . grade, and only transformers can be included according to user needs. Suitable for no-load long-distance kilometers without re-ignition.
Product features:
The product has excellent breaking performance. It uses a compressed air type to extinguish the arc chamber. It has short arcing time and long electrical life. It can continuously break under the rated voltage. The short-circuit current reaches times without maintenance. The machine has high reliability without replacing hexasulfur gas. It has a mechanical life of more than 10 times and can be operated frequently. Each unit can be equipped with only one current transformer for users to choose. This product adopts a new type of pointer density meter. The pressure gauge reading is not affected by temperature changes and is easy to use. The circuit breaker complies with the requirements of National Standard B "AC High-Voltage Circuit Breaker" and International Electrical Standard Publication C "High-Voltage AC Circuit Breaker". This product is equipped with a C-shaped spring mechanism.
.., .. type outdoor high-voltage sulfur hexafluoride circuit breakers are suitable for use in urban power distribution stations and industrial electrical equipment powered by substations or terminals for protection control and short-circuit protection. Due to the protective effect of the outdoor high-voltage sulfur hexafluoride circuit breaker on electrical equipment such as transformers, it can control line breaks, overloads, and inrush currents, effectively protecting transformers, electrical equipment, and lines. More reliable and economical, it is especially suitable for ring networks, double radiation power supply units and box-type substations.

Structure and working principle:
The circuit breaker has two modes: parallel transmission and vertical transmission.
The circuit breaker has a porcelain column structure with three separate phases. Both have compressed gas arc extinguishing chambers. The three-phase gases are connected through copper tubes. The circuit breaker is composed of a pillar porcelain bottle, a current transformer, an arc extinguishing chamber, an absorber, a transmission box, a connecting rod, a chassis and a spring operating mechanism.
.Porcelain sleeve
The porcelain sleeve is a supporting and insulating component for connecting the main circuit of the circuit breaker to the power system. Since it is connected to the circuit breaker shell and is an integral part of the pressure vessel, it has high strength and air tightness. good.
The arc extinguishing chamber of the .&. type circuit breaker is mainly composed of static contacts, moving contacts, porcelain sleeves, cylinders and nozzles. The porcelain sleeves and insulating tie rods form the ground insulation of the moving and static contacts. .
.&Adsorber
The adsorber is an aluminum alloy container. Each type circuit breaker has six absorbers, but three of them are placed in the transmission box and three are installed in the cooling cap. The adsorber is equipped with a molecular sieve, which is used to adsorb the water in the sulfur hexafluoride gas and the low fluoride formed by the decomposition of the arc.
Ordering Notes:
When ordering, please indicate the operating voltage and current transformer model and wiring requirements of the energy storage motor and opening and closing coils in the mechanism (under normal circumstances, the special tools and Number of spare parts, whether transition brackets are required.
