Product introduction Overview: 3-Series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker< br/>) It is used in three-phase power systems with AC and rated voltage to divide and combine load current, overload current and short-circuit current. The circuit breaker can be configured with a reclosing controller that can identify current characteristics and realize multiple automatic reclosing or isolation of permanent faults. It is self-contained as a power supply and becomes an intelligent circuit breaker with voltage and current signal output and controllable. It is powered by electronics and can complete the process. Three-stage composite protection of current delay, inrush delay and short-circuit quick-break. 3. Functional features 3/type outdoor high-voltage vacuum circuit breaker
3-/type outdoor high-voltage vacuum circuit breaker is equipped with a spring operating mechanism, which has the functions of breaking and closing load current
, overload current and short-circuit current, etc. The basic function is the basic model of the 3-series. The combination of circuit breaker and isolation switch can form a combination circuit breaker with obvious break (hereinafter referred to as combination circuit breaker). Users can choose to use a silicone rubber insulating sheath on the isolating switch. This sheath is resistant to rain, snow, wind, sand, and dirt and corrosion, and can effectively prevent freezing and oxidation of the isolating switch. The circuit breaker can be equipped with a lightning arrester, which can be installed on either side of the incoming and outgoing lines according to user requirements. The circuit breaker can be equipped with an inrush current controller, so that it has the function of avoiding inrush currents and overcurrent rapid breaking. The circuit breaker can be installed ~3 A measuring or metering transformer
. Type 3/ outdoor high-voltage vacuum circuit breaker 3-/ type outdoor high-voltage vacuum circuit breaker has all the functions of a basic circuit breaker, and is equipped with a reclosing controller to form a recloser-type intelligent circuit breaker. The basic type is suitable for occasions with easy access to power supply when combined with a reclosing controller. The basic type is suitable for occasions when there is no power supply when combined with a reclosing controller. The intelligent circuit breaker is suitable for radial power supply and ring network power supply systems to help the system eliminate instantaneous faults and automatically recover. Power supply can also isolate permanent faults and realize distribution network automation. The smart circuit breaker has ~3 times of reclosing function, and the recloser parameters can be adjusted. The smart circuit breaker has the functions of closing inrush current control, overcurrent protection and short-circuit quick-break three-stage composite protection, and the parameters can be continuously adjusted. The smart circuit breaker has small current
Ground protection function, and the parameters can be continuously adjusted. The intelligent circuit breaker can realize both wired remote control and wireless remote control under the pole. 3.3/type outdoor high-voltage vacuum circuit breaker
3-/type outdoor high-voltage vacuum circuit breaker has all the functions of the basic circuit breaker. This type of circuit breaker is equipped with a voltage transformer
. The voltage transformer switches from the line high voltage to The circuit breaker (small hydropower type) can be used to monitor the line voltage. When overvoltage or undervoltage occurs, the circuit breaker controls The circuit breaker automatically disconnects the circuit breaker and can be widely used at the grid-connected branches of small hydropower branches and the main power grid to realize network monitoring and automatic fault isolation. The circuit breaker (metering type) can output voltage and current with . signal, it is an ideal choice for rural power grid substations, off-site scattered switches and simple metering switches. 3/Electronic outdoor high-voltage vacuum circuit breaker 3-/Electronic outdoor high-voltage vacuum circuit breaker has all the functions of a basic circuit breaker. This type of circuit breaker is equipped with electronics, which can draw power from the battery to charge the battery, and can operate under a voltage loss state. Multiple energy storage and opening and closing operations, and can provide the working voltage of external equipment. It has the functions of closing inrush current control, overcurrent protection and short-circuit quick-break three-stage composite protection. The protection parameters can be continuously adjusted by the user, and wired remote control can be realized. , it can also be controlled wirelessly under the pole.
