Indoor high-voltage vacuum circuit breaker
Outdoor high-voltage vacuum circuit breakers:
ZW32-12 type outdoor high voltage vacuum circuit breaker(also named as vacuum switch) is rated voltage 12kV, three-phase AC 50Hz outdoor distribution equipment, which is mainly used for breaking, closing power system load current, overload current, short-circuit current. For substation and industrial and mining enterprises distribution system for the protection and control of the role and place of rural power grids frequent operation.
The circuit breaker has small size, light weight, anti-condensation, maintenance-free characteristics, can adapt to poor weather conditions and dirty environments.
The models with permanent magnet operation mechanism operates: since the permanent action energy operating mechanism provided by a permanent magnet, the switch quickly to keep the points off position, a small number of mechanical parts, mechanical transmission chain is short, thus greatly improving the switch reliability and mechanical life.
Vacuum circuit breakers are named for their high vacuum arc extinguishing medium and the insulation medium between the contacts after arc extinguishing. They are widely used in power distribution networks due to their advantages of small size, light weight, suitability for frequent operations, and no need for maintenance after arc extinguishing. Vacuum circuit breakers are indoor distribution devices in 3-10 kV, 50 Hz three-phase AC systems. They are used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. They are particularly suitable for places that require oil-free operation, minimal maintenance, and frequent operations. The circuit breakers can be installed in switchgear, double-layer cabinets, and fixed cabinets for controlling and protecting high-voltage electrical equipment.
Power Safeguarded: Indoor and Outdoor High-Voltage Vacuum Circuit Breakers
Indoor and outdoor high-voltage vacuum circuit breakers are two commonly used types of circuit breakers in power systems, each serving a distinct purpose in different environments. Here is a brief introduction to them:
Indoor high-voltage vacuum circuit breaker
s:
Installation location: Indoor high-voltage vacuum circuit breakers are typically installed in indoor distribution equipment rooms, switchyards, or control cabinets.
Key features: They are used to protect and control high-voltage power lines, substations, and distribution systems. Indoor high-voltage vacuum circuit breakers utilize vacuum as the arc extinguishing medium and swiftly interrupt circuits in the event of overcurrent, short circuit, or other faults to safeguard equipment and personnel.
Application scope: Indoor high-voltage vacuum circuit breakers are suitable for medium to small-sized substations, industrial complexes, commercial buildings, and other indoor environments. They are compact, lightweight, and designed for frequent operations and compact spaces.

Outdoor high-voltage vacuum circuit breakers:
Installation location: Outdoor high-voltage vacuum circuit breakers are specifically designed for outdoor environments and are typically installed in power transmission lines, substations, or outdoor switchgear.
Key features: Outdoor high-voltage vacuum circuit breakers provide protection and control functionalities in power systems and can operate reliably under harsh outdoor conditions. They possess features such as dust-proof, waterproof, and weather-resistant capabilities, enabling them to interrupt circuits effectively and prevent further fault propagation and equipment damage.
Application scope: Outdoor high-voltage vacuum circuit breakers are applied in power transmission lines, substations, and locations where power distribution and control take place outdoors. They are designed to meet the unique requirements of outdoor environments, ensuring high reliability and adaptability.
