Product Overview
    FLM3 series of city network dedicated distribution network intelligent circuit breaker (manual coincidence type) is to develop and produce according to the requirements of the control device and the low voltage circuit breaker protection, low voltage city network power system fully integrated with the countries of the technical indicators and the operation and management of , has a high breaking capacity, low temperature, long life, high electrical insulation properties advantages and widespread use can greatly enhance the economic security of the entire low-voltage distribution network, and meet the intelligence requirements of the national grid, the communication interface monitoring device interface and terminal connections, over-current, over voltage, overload and other real-time data upload and implementation of accurate repair of power system fault, and in accordance with the requirements of the monitoring center to ensure safe and reliable low-voltage distribution network run and continuity, guarantee on the whole power grid 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, the LDC Chinese real-time monitoring of network information, real-time display of each phase 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 of the 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 (the VS), effective against lightning induction, the elimination of a variety of harmonic interference, stable and reliable.
Equipped with mechanical short-circuit backup protection, the failure to prevent electronic short-circuit function.
National patent products, has been the Ministry of Information Industry inventions, 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.
Quickly and accurately identify the type of fault, a permanent fault isolation, exclusion of transient fault protection network is working properly.
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
Failure points off time is adjustable, fault movement is adjustable, can be used for the protection of Taiwan Chief or sub-protection grade trip and at the same time tripping phenomenon does not occur, work load current can be set according to the Taiwan District, the transformer size, it will not and burnt the transformer due to overload.
Use of intelligent controlTechnology, network management and remote monitoring, and also to 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.
