Product Overview
FLM3 series of rural power distribution network intelligent circuit breaker (manual coincidence type) according to the leakage protector devices and low-voltage circuit breakers in low voltage rural power electricity system, fully integrated with the technical indicators and operation and management to develop and produce has high breaking capacity, low temperature, long life, high electrical insulation properties advantages and widespread use can greatly enhance the economy and security of the entire low-voltage distribution network, and meet the intelligence requirements of the national grid, communication interface and terminal control device interface connections, leakage, over current, over voltage, overload and other real-time data upload precision, power system fault repair, and in accordance with the requirements of the monitoring center to ensure that the, low voltage distribution network t, o run a safe, reliable 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-under voltage, leakage, lightning, real-time communication and other functions, complete with 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. Sub-anti-jamming capability, using advanced anti-lightning residual voltage circuit configured with high-intensity transient suppressors (under VS), can effectively fight against lightning sensor, eliminating all kinds of harmonic interference, stable and reliable operation.
Equipped with mechanical short-circuit backup protection, the failure to prevent electronic short-circuit function. 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, leakage, short circuit protection to ensure that the electrical environment, equipment and personal safety. The independent body electric shock protection processing unit, set the leakage and electric shock, respectively, independent analysis of the control channel. Line leakage is generated by one or more phases of the leakage vector processing unit can be an electric shock in any one phase of the received <50mA current, and <0.15s trip protection. For a short time or a sudden increase in leakage current, leakage values did not exceed the set the action value, still reliable power supply. This feature greatly improves the safety and reliability of the electricity. This lightning protection function can be 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, adjustable leakage current action value (fault action values), can be used for the protection of Taiwan Chief or sub-protection grade trip and at the same time tripping phenomenon does not occur, the work load current transformer size according to the Taiwan District set, will not be overloaded and burned the transformer.
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.
