SanGao's 12kv Indoor Vacuum Circuit Breaker made in China is an indoor distribution device in three phase AC systems, which can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is particularly suitable for use in places that require oil-free, low maintenance, and frequent operation. Circuit breakers can be configured in central cabinets, double layer cabinets, and fixed cabinets for the control and protection of high voltage electrical equipment.
The number of components for fixing the sealed pole is greatly reduced, the structure is simple, the installation is convenient, the manufacturing process of the circuit breaker is simplified, and the reliability and stability of the circuit breaker are greatly improved.
Has good moisture proof and anti condensation properties. It is suitable for high temperature and humid areas.
1. Due to the embedded epoxy resin insulation material in the vacuum arc extinguishing chamber, the original surface insulation becomes volume insulation without further treatment. The fixed sealing pole can achieve higher insulation strength, which is more conducive to the miniaturization design of circuit breakers and switchgear.
2. The vacuum arc extinguishing chamber and related conductive components are simultaneously embedded in epoxy resin solid insulation material, shielding the influence of external environment and completely maintenance free during product use, making it highly adaptable and strong in strength. It can be widely used in chemical, metallurgical, mining and other fields.
Although the production cost is high, the low resistance vacuum arc extinguishing chamber and outlet socket are sealed in the epoxy resin main circuit, which improves the insulation level and anti pollution ability, and eliminates the influence of condensation.
4. According to the usage environment of the switchgear, adopting a fixed sealing rod can better meet the needs of more users, improve the reliability of the switchgear, and enhance the reliability of the power grid supply.
Fixed type is fixed to the rack inside the cabinet with screws, easy to install, and cheaper than the handcart type. It is a maintenance and safety handcart type.
The handcart type allows the switch to be pulled out of the cabinet, making it easy to maintain. Installation is more complicated and expensive than the fixed type.
