RMFK capacitor switch switch (referred to as composite switch)
Overview:
RMMF series intelligent composite switch (electronic capacitor switch switch hereinafter referred to as composite switch) is a new generation of electronic products, there are two kinds of complementary and sub-fill type, a variety of composite switch for switching three-phase capacitor, using Δ wiring law. Sub-type composite switch for switching single-phase capacitor, the use of Y-type connection, the new generation of composite switch is the biggest advantage of the use of single-chip technology, software and hardware is the compound, according to the three-phase alternating current characteristics, A number of AC cycles according to the phase of the phase, the use of single-chip program on the controlled capacitor switching operation, in order to achieve the parallel capacitor without current and no over-voltage switching process, the composite switch with no impact, Long life, low failure and other significant advantages, can replace the contactor, thyristor switch, ordinary composite switch, widely used with low voltage reactive power compensation field.
Conditions of Use:
1, the use of temperature: ~ 25 ℃ ~ 55 ℃, storage transport temperature -30 ℃ ~ 65 ℃.
2, relative humidity: 56% to 95%, no condensation atmospheric pressure 80Kpa ~ 110Kpa.
3, the altitude of not more than 2000 meters, the address strength is less than 8.
4, the surrounding environment without corrosive gases, no conductive dust, no flammable and explosive medium exists.
5, the voltage fluctuation range is not more than the rated voltage ± 20%.
Features
1, the voltage zero-crossing input, current zero-cut, no surge, no over-voltage.
2, switch low power after switching, does not produce harmonics.
3, the input signal and switch isolation, high EMC protection measures, anti-interference ability.
4, can be directly with the company's dynamic reactive power compensator controller used in conjunction.
5, the switch running state with sub-gate closing, phase, delay, power indicator.
6, the switch has enhanced integrated protection function, including the system input voltage phase protection. Power failure protection, self-diagnosis fault protection function.
Indicator indicator
1, the power delay indicator O.VO.V fast flashing when the switch is now in a delay state, O.V in the slow flash when the switch is in normal working condition.
2, the lack of fault indicator O.LO.L light that when the three-phase input at least one phase phase loss, or other failures, a total of complementary type switch (electronic capacitor switch switch) with phase failure protection function.
3, closing indicator light ABCABC three-phase closing in the light state, when the lights off, when the sub-type composite switch ABC three-phase is the same time, sub-composite switch ABC three-phase control, asynchronous The
The main technical parameters
1, rated voltage: a total of AC380V; sub-AC220V ± 20%, the service life of 100,000 times.
2, switch pressure: ≤ 2000V; switching power consumption ≤ 2W.
3, switch pressure: ≤ 0.1V; breaking interval ≥ 20S.
4, insulation strength: 2.5KV / 1min, allowing harmonics <10%.
5, control voltage: DC12V with zero line (N).
Precautions:
1, sub-fill type composite switch and capacitor connection using Y-type connection, that is, switch three output termination (each one) three single-phase single-capacitor end, another fuse collar (N).
2, in the harmonic content of more than 5% of the occasions under the compound switch, it is recommended to take harmonic control measures according to the situation.
3, composite switch is not suitable for frequent switching places, recommended switching time interval of more than 20 seconds.
4, vertical installation, diagonal fixed, the use of rail installation or use up and down two U-shaped iron plate fixed, prohibit the use of iron plate seal fixed.
5, the use of composite switch to pay attention to the capacitor capacity is now appropriate, wiring is firm, generally optional small circuit breaker as a separate breakpoint.
6, the use of sub-fill type composite switch, single-phase capacitor zero line must be in good contact, otherwise it will likely cause the composite switching power supply zero line bearing too high, resulting in zero line current damage.
Note: This composite switch B phase long-term live, the use of careful shock.
7, a total of complementary type composite switch B phase long-term live, when used with care.
8, sub-fill type composite switch for the first time to get to A.B.C three-phase asynchronous pull, the first time can not be synchronized pull.
Ordering Information:
1, the sub-fill type composite switch to select the power, refers to the sum of three single-phase capacitor capacity ≤ switch rated current.
2, the composite switch rated current selection, the proposed capacitor capacity 1 ~ 20Kvar 40A composite switch, 20 ~ 40Kvar 70A composite switch.
