1. Application and characteristics< br/>
The outdoor vacuum circuit breaker adopts a spring energy storage operating mechanism, which can realize electric energy storage, electric opening and closing, and can also realize manual energy storage and manual opening and closing. It is suitable for use as protection and control appliances in three-phase power systems with rated voltage and frequency. Due to the special advantages of vacuum circuit breakers, it is especially suitable for places that require frequent operations at rated current or multiple short-circuit currents.

The outdoor high-voltage vacuum circuit breaker isolation switch combination appliance is composed of a high-voltage vacuum circuit breaker and a high-voltage isolation knife. It is called a combination circuit breaker. Xi'an Naidian Electric Power Equipment Co., Ltd. can be used as a segmented circuit breaker. switch is used. The isolating switch does not have an arc extinguishing device. Although the regulations stipulate that it can be operated in situations where the load current is less than Open to ensure the safety of construction workers and line operations. The circuit breaker is referred to as a switch in use, and the isolating switch is referred to as a knife switch in use. The two are often used together.

3. Structure of vacuum circuit breaker

) The overall structure is three-phase common box type

) Vacuum arc extinguishing chamber

) Spring operating mechanism

) Insulation system

) Conductive circuit

) Box cover, box body
< br/> ) Seals

4. Vacuum circuit breaking characteristics

) Current transformers can be installed according to user needs. The outer insulation is a high-voltage silicone rubber sleeve and the inner insulation is composite insulation.

) Built-in multi-tap current transformer can be used for over-current protection

) Double-winding current transformer can be used for protection and measurement

) If voltage transformers, automatic reclosing controllers, and automatic segmenting controllers are installed, distribution protection automation and four remote (telemetry, remote signaling, remote control, and remote adjustment) functions can be realized. A composite controller (elimination of the gate inrush current).

) An isolation switch can be installed

5. Instructions for ordering vacuum circuit breakers

Users need to provide the following technical information when ordering

) Circuit breaker model, name, quantity.

) Rated current, rated short-circuit operating current.

) Operating mode, operating voltage.

) Equipped with current transformer current ratio.
