Product function and characteristics

The main function:

- Protection function: Automatic identification of fault current, fast breaking current, fast breakthrough time limited current, time-to-time, overcurrent orientation, overvoltage, undervoltage, single-phase protection in low current grounding system, cooling load operation Suppression and break

- Measurement function: Measure the three-phase current, 3-phase voltage, active power, reactive power, active energy, reactive power, peak / valley energy, power factor and frequency, etc.

- Control function: Local and long-distance remote control, automatically restore the fault location, isolation failure, and quickly restore the non-fault line power supply, and the load is automatically detached, the capacitor automatic switch, the backup power supply automatic switch, etc.

-Intelligentization function: Comprehensively analyze the performance characteristics of online meter parameters, circuit breakers, and network programs when cooperation with power transmission automation system, and implement remote control and management of switching equipment, realizing on-site, remote or hierarchical control power Assign an automation system function.

- Data Recording Function: Reserve the latest 256 data records, operations, and fault information.


Optional function:

- The dedicated remote control can optionally be selected to achieve remote control, cutting and recovery power, no need to climb to the rod.

-Backup power automatic control cabinet can optionally be automatically switched between dual power lines.

- The high voltage isolation of integrated design can optionally be selected to make the structure compact, easy to install and maintain.

-Super capacitor or battery (lead acid or lithium battery) can optionally select for backup power sources.

- Fault waveform recording function can be implemented to maintain up to 50 data records.

- Automatic re-off function can optionally be selected.

-GSM mobile SMS function can optionally select the motion information of the switch to send to the specified user.

According to customer requirements - GPRS communication and fiber optic communications, China and English text messages are available. Provides RS232 / RS485 and RJ45 Ethernet ports, the communication protocol can be flexibly equipped with, support like 101, 104, etc., various communication protocols and derivative protocols, etc.

-Synchronous Tight Open Technology: Depending on the discrete of load characteristics, adaptive switch parameters and environmental factors, simultaneous closing - open, suppress overvoltage operation and closing surge search zero intersection, effective, especially suitable for switch capacitors and transformer.


Main features:

- Use 3 single-phase permanent mechanism ö to reduce the number of assembled parts and reduce the cleaner significance. Stable and reliable. There is no need to do regular maintenance.

- Use an outdoor hydrophobic epoxy resin as an external insulating material, light weight, long service life (more than 15 years old), good weathering, oil-free, no sf6, compliance with environmental requirements.

- Use a fast algorithm to obtain rapid breaking capacity for circuit breakers. As a result, it can quickly isolate the fault circuit. If we take 12kV circuit breakers as an example, it requires smaller failure circuits than 25ms from check faults. It can effectively avoid the problem of cross-level trip.

- With a single-phase ground protection system, it can achieve online judgment, and the small current grounding system is single-phase ground fault does not increase the device. Publish a warning or action trip according to the set value

-Apply is currently the most advanced embedded operating system; the structure of dual CPU, including ARM9 universal processing and system control, and processing strong DSP with multi-tasking high efficiency; and implement high-speed data processing, control, and communication.

- It has automatic re-shutdown to effectively prevent the function of power failure due to instantaneous failure. The power distribution network can also complete fault isolation and automatic recovery power supply without the need for the main station.

- Convenience, whether manually open / close operation, or wireless remote operation. Remote distance is more than 50 meters.

- Using synchronous open / closing techniques to achieve synchronous on / off of circuit breakers and effectively suppress overvoltage and surges.

- Built-in high-precision current transformer; according to customer requirements, real current protection, without external CT like transients, time limited fracture, time-free overcurrent protection, etc.

- Built-in voltage sensor; measurement and acquisition of phase voltage and zero-sequence voltage, low voltage protection, and single-phase ground protection, according to customer's request

- Flexible communication method; support GSM short message, GPRS, CDMA general wireless service, fiber, twisted pair, wireless carrier, and other communication methods, and support various communication protocols.

- Temperature measurement and modification techniques to operate reliably and stably under different environmental conditions across the country.

- Professional power management module provides automatic switching functions for two power input wires (AC / DC 100 / 220V); at the same time, it has a professional battery management.

Control system - friendly operation interface; China / English version of the system; convenient, fast, parameter settings. The user-friendly manual interface port provides convenient search for parameter settings and motion records. It has a data recording function that retains the latest 256 data records, operations, and fault information.

- It is capable of adding integral separation of a compact, reliable mechanical interlocking structure. It can effectively prevent errors.

Non-corrosive and maintenance characteristics of overall stainless steel body.
