Product Overview
    FLM3 series of urban network of dedicated distribution network smart breaker (recloser type), control devices and low voltage circuit breaker in the low-voltage city network power system protection, development and production of fully integrated with the technical indicators and operation and management of , with a high breaking capacity, low temperature, long life, high electrical insulation advantage. Line over-current, short circuit, over-voltage lack of phase, off zero fault can be quickly cut off the supply line, after the failure to eliminate the automatic reclosing connected to power lines, no artificial closing widespread use can be very The large increase of the economy and security of the entire low-voltage distribution network, and with the intelligence requirements of the national power grid, communication interface with the terminal control device interface connections, leakage, over current, over voltage, overload, real-time data on pass, according to the requirements of the monitoring center and power system failure in accurate repair to ensure safe and reliable low-voltage distribution run and continuity, to ensure that on the whole grid-powered intelligent.
Features
The product is integrated in one, with automatic downshift, overload, short circuit, phase loss, over the under-voltage, lightning, real-time communication features such as fully intelligent digital control, the action value reliable, accurate and correct. Both to protect the safe use of electricity can do a reliable power supply.
High-performance single-chip process control, and dagger DC Chinese display, real-time monitoring of network information. Real-time display of each phase of the load current, the maximum phase of the leakage current, voltage and other operating data. By failure to stem node output fault information, can monitor real-time upload.
High breaking design (limit short-circuit breaking capacity} cu; 50kA), breaking the high-capacity, small size, beautiful appearance, short arcing.
Anti-interference ability, the use of advanced anti-lightning residual voltage circuit, equipped with high-intensity transient suppressors (D VS), effective against the induction of lightning, the elimination of all harmonic interference, stable and reliable operation.
Automatic reclosing procedure
The overload points overload current can be set, breaking time can be set.
Over-load closing three procedures (by the user needs to be set)
  The first time: the overload trip, an interval of 10 minutes automatic switch on.
  The second: After closing detect the overload current to drop to the safety of current continues to run. If there are still 1.3 times the current trip, the trip after an interval of 20 minutes and then automatically closing.
  The third: After closing still more than 1.3 times the current trip to lockout.
Short circuit protection: Short-circuit current in multiples of time can be set.
The first time: the short-circuit current is 10 times the rated current, jump l The ’time of less than 180 milliseconds (200 milliseconds) National Institute of Standards automatic closing after 15 minutes after the trip.
Rapid detection of load line, the second: after closing if normal continue to run, short-circuit fault exists, ie, 2 times the current 120 ms trip atresia.
Equipped with mechanical short-circuit backup protection, the failure to prevent electronic short-circuit function.
Over voltage protection, circuit breaker automatic closing operation when the power supply voltage is restored to normal voltage j0% error.
Communication interfaces to meet the needs of the smart grid, from time to time to send the end of the distribution lines of the technical data, and in accordance with the instructions of the control center jump, closing, and make sure the distribution security, intelligence, reliability Sub-national patent products has been the Ministry of Information Industry invention and utility models, designs a number of patents.
Quickly and accurately identify the type of fault, a permanent fault isolation, exclusion of transient fault protection network is working properly. Improve the over-current, over voltage, short circuit protection to ensure the electrical environment, equipment and personal safety. Lightning protection feature multiple levels of protection equipment to reduce damage to the chances of extending the time span of the user equipment.
Failure points off time is adjustable, adjustable leakage current action value (fault action values) for the protection or grading protection of Taiwan Chief grade trip and at the same time tripping phenomenon does not occur, the work load current according to the size of the transformer capacity of the Taiwan Area set, would not have burned the transformer due to overload.
Intelligent control technology, network management and remote monitoring, and also launch fault trip to the duty officer on the phone, the timely processing of the scene incidents to restore power as quickly as possible according to user requirements.
