main feature:

Three permanent magnet operating agencies, several components, low off current, stable work, no need to maintain frequent maintenance, long mechanical life is 100,000 times.

Using an outdoor hydrophobic epoxy resin as an external insulating material, light weight, longer life time of more than 40 years, oil-free and SF6, non-polluting environment, unoccupable gas leakage, in line with environmental protection requirements.

Use a fast algorithm to make the circuit breaker with fast breaking capabilities, fast isolation fault lines. From checking failures to cutting circuit breaker fault lines less than 25 milliseconds (10kV), and effectively avoid excessive trip problems.

Using a single-phase ground protection system, a new device does not add a single-phase ground fault to a small current grounding system. And release a warning or trip action based on the set value.

The built-in voltage, current sensor, can extract various measurement and high precision protection of no external PT and CT without electrical parameters.

With automatic reclosing function, it can effectively avoid the ability to automatically complete the fault isolation and recovery of physical strength due to instantaneous fault power failure accidents.

Use temperature measurement and correction techniques to make the switch work reliably and stably under different environmental conditions.

Stainless steel box, no corrosion, maintenance-free.

Professional battery management modules, you can provide the second energy transfer (AC / DC100, 220V) automatic switching function, and has a professional battery management.


Optional feature:

Special remote control can realize remote control operation, without climbing the upper power and transmitting operation;

The backup power supply automatic control box can automatically switch between dual energy transmission lines;

Have integrated design (circuit breaker of 10kV) high pressure isolation, making the structure compact, installation and inspection;

Super capacitors or batteries (lead acid or lithium batteries) are used as a spare power;

Fault recording function, you can save the latest 50 data records;


Automatic reclosing function;

The short message feature of the GSM mobile phone can use the mobile user specified by the switch action information.

Optional GPRS wireless communication and fiber communication, supporting China, British short messages, providing RS232 / RS485 and RJ45 Ethernet ports, and communication protocols can be supported flexibly, support 101, 104, 61850, and other communication protocols and derivative protocol configurations.

Optional Hand PDA can implement remote messaging, telemetry, remote control, remote function adjustment, controller sends a self-test command in the PDA, and transmits self-test information feedback to the PDA terminal.

Switching technology optional synchronization: based on load characteristics, automatic search of zero intersections, adaptive switch parameters discrete and environmental factors, implementation of shutdown action synchronization, suppressing overvoltage and effective switch surge, especially adapted to switch Capacitors and transformers


Main function:

Protective functionAutomatically identify fault current, realize instantaneous cut-off current, time limit current, time overcurrent, directional overcurrent, overvoltage, undervoltage, small current grounding system single-phase ground protection, cold load start suppression breakpoint function, etc.
Measurement functionMeasure the three-phase current, three-phase voltage, active power, reactive power, active energy, reactive energy, peak / valley electricity, power factor, and frequency, etc.
control functionField operation and remote control can be realized, and the location of the line failure can be automatically implemented, the power supply of the non-fault line can be automatically realized according to the needs of the line failure, and the low frequency automatic load, automatic switching function of the capacitor, and other controls. Features.
Data recording functionRecord and save the operation, and automatically fault information.
Intelligent functionYou can perform the network parameters of the upper line, the performance parameters of the monitoring line circuit breaker, online programming, cooperate with the automatic system master of the distribution network, to realize remote control management of switching equipment, implement local, remote and hierarchical control type network automatic System functions.
