MWFK Series Intelligent Switching Composite Switch
MWFK Series Intelligent Switching Composite Switch
1. Overview
MWFK series intelligent composite switch (hereinafter referred to as cutting compound switch) is a new generation of electricity children were filling products, and type two kinds, composite switch used for cutting threephase electricity containers, have the train. Points for composite switch for single-phase capacitor, cutting. The letter "Y". The new generation of compound switch the biggest advantage of using single ship microcomputer, is soft pieces of hardware and the compound. Work according to the characteristics of the three-phase ac sequence in several according to each phase flow within the period of phase, micro controller program runs relatively accused of capacitor cutting operation, so as to realize the parallel is the freshness and over compaction cutting process, Compound switch has no impact on high, low power consumption, low malfunction, service, etc. In stead of touch, thyristor switch, common compound switch, widely used in low voltage reactive power claims.
2. Conditions of use
1. Use temperature: -25`~55 degree Celsius store and transportation temperature -30 degree C~65`C.
2. The relative humidity: 5%~95%, atmospheric pressure 80Kpa~110 Kpa naked.
3. And altitude of more than 2,000 meters, not less than 8 magnitude earthquake intensity.
4. And surrounding environment without decay gas, dust, no inflammable, explosive conductive medium existence.
5. And voltage fluctuation range is not more than the rated voltage +/-20%
3. Function characteristics
1. Voltage, current zero, zero, do not produce over-voltage without currents.
2. After switch, low consumption and no harmonics.
3. And the input signal and the switch photoelectric isolation, EMC protective measures, strong anti-jamming capability.
4. And can be directly with our dynamic reactive compensation controller. (And capacitor)
5. Switch to run sate has break-brake feeder, lack of power, delay.
6. And switch with enhanced comprehensive protection function, including the system input voltage phase, power protection, since the diagnosis fault protection, etc.
4. Indicator instruction
1. The power indicator PDP, delay when opened rapid flashes D in a state of delay. P,D in slow flashing switch in normal working condition.
2. Phase failure indicator, LO, L bright says at least a three-phase input in phase, or other malfunction. Total composite switch is for the protection of phase velocity.
3. A,B, feeder indicator, B, CCA three-phase when lights in the state, break-brake lamp. For A total of compound switch B, C is also divided, three points for A compound switch type B, C three-phase asynchronous and controlled, divided.
5. Main technical Parameter
1. Rated voltage up AC380V POINTS: for AC220V+/-20%, use life 100,000 times.
2. Switch 2000V switch power voltage: acuities than 2W
3. Switch pressure resistance than 0.1V: 20S, high interval acuity.
4. And insulation intensity: 2.5KV/1 min, allowing the harmonic<10%
5. And the control voltage DC12V: with neutral (N).
6. Ordering instruction
1. The composite switch choice for power, refer to the total capacity of the three phase capacitor is rated current of the switch.
2. Rated current of compound switch, suggested by 1~2% Kva capacitance capacity 40A compound switch, 20~40Kvar 70a-tusing composite switch.
7. Mode and implication
