Summary
Zw32abg-12 intelligent outdoor high-voltage intelligent vacuum circuit breaker (" intelligent circuit breaker ") is an outdoor high-voltage switchgear with a three-phase ac 50Hz rated voltage of 12KV.It is suitable for load current, overload current and short circuit current of power distribution system in open and closed cities or rural areas.
The circuit breaker is a brand new miniaturization design.Fully enclosed structure, unique arc extinguishing chamber encapsulation technology, good sealing performance, moisture-proof, anti-condensation, suitable for hot and humid area.
Zw32abg-12g is a high-voltage switchgear which is composed of ZW32 circuit breaker and isolating switch.
Main advantages
1. Zw32abg-12 is equipped with intelligent measurement and control system (abbreviated control box). The control box is convenient in appearance and small in size.According to the requirement, it can be equipped with built-in control protection, self-provided operation power supply and long-term charging mode.Therefore, it can realize the functions of "three remote" and "three paragraphs" control.
2. Zw32abg-12 can also be equipped with a unique integrated runway type zero-sequence transformer, and the output of the second zero-sequence current value is more accurate.In the power system, the current imbalance of ABC three phase, line fault (such as single phase grounding) has accurate memory and recognition, and permanent automatic protection and isolation.Minimize the power outage and reduce the safety factor of personnel injury greatly.
Types of meaning
Example: zw32abg-12 means outdoor ac high voltage vacuum circuit breaker, with outdoor partition switch, electrophoresic stainless steel case, electric mechanism, rated switching current is 20kA.
