Product model and name
-Series outdoor high-voltage vacuum circuit breakers
Main uses
-Series outdoor high-voltage vacuum circuit breakers (hereinafter referred to as circuit breakers) are used for AC , In three-phase power systems with rated voltage, it is used 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.
Functional features
3. -/type outdoor high-voltage vacuum circuit breaker
-/type outdoor high-voltage vacuum circuit breaker is equipped with a spring operating mechanism, which has the function of breaking and closing load current, overload current and Basic functions such as short-circuit current are the basic models of the - series.
When used together with the isolating switch, the circuit breaker can form a combination circuit breaker with an obvious break (hereinafter referred to as the 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 functions of avoiding inrush currents and overcurrent rapid interruption
The circuit breaker can be equipped with ~3 measuring or metering transformers.
3. -/type outdoor high-voltage vacuum circuit breaker
-/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 adjusted Continuous setting
The intelligent circuit breaker has a small current grounding 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/Type outdoor high-voltage vacuum circuit breaker
-/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 is connected from the high-voltage side of the line. Taking power, it can provide voltage to itself or other control equipment as needed
This circuit breaker (small hydropower type) can be used to monitor line voltage. When overvoltage or undervoltage occurs, the controller automatically opens the circuit. The circuit breaker 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
This circuit breaker (metering type) can output voltage and current signals with . , 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
-/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 to draw power from the battery. Charging, it can perform multiple energy storage and opening and closing operations in the voltage loss state, 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
It can realize both wired remote control and wireless remote control under the pole.
