Abstract
The utility model is a reactive compensation device for an expressway LED lamp or road LED lamp circuit. The main characteristics of the device are that an electric reactor is adopted as a reactive compensation element, the switching on or switching off of the electric reactor is controlled through a contactor, the contactor is controlled by a temperature controller on the electric reactor to achieve overheating protection, and the temperature controller controls the starting and closing of a cooling fan.
Description
Technical field
highway LED street lamp or highway LED street lamp power system reactive power compensation.
Background technology
highway LED street lamp or highway LED street lamp Voltage Cable Lines Construction grow now idle sending, and traditional low-pressure reactive compensation equipment is electric capacitor compensation, not competent this type of reactive power compensation demand.Power supply department will be examined monthly average power factor, due to street lamp, working cable capacitive reactive power is not idle much larger than no-load transformer perception daytime, the extremely low only 0.05-0.3 of power factor, evening when street lamp bright light power factor may up to standardly reach leading 0.9 but average power factor lower than 0.9, average power factor can not reach 0.85 or 0.9 standard that power supply administration requires, power supply administration adjusts way according to power rate will add demand charge, therefore need development for this electricity consumption situation reactive power compensator.
Utility model content
(1) technical problem that will solve
The utility model
the technical problem solving is that public lighting circuit metering device causes idle sending to each case change Voltage Cable Lines Construction length.
(2) technical scheme
addressing the above problem for realizing, is originally that utility model adopts following technical scheme
the utility model provides a kind of 10KV power circuit reactive power compensator, and this device comprises shunt reactor, and described reactor is in parallel with 400 hint roads by air switch QS and contactor KM.In the time that reactor L temperature reaches fan starting temperature, often open temperature detect switch (TDS) FR2 and connect fan running heat radiation, in the time that reactor L reaches the limiting temperature of setting, normally closed temperature detect switch (TDS) FR1 cuts off contactor KM coil power protection reactor.Air switch QS facilitates inspection operation, plays overcurrent and short-circuit protection simultaneously.
wherein, this device also comprises between A.C. contactor connection and air switch and reactor.
wherein, this device also comprises between air switch connection and power supply and contactor.
wherein, this device also comprises that radiator fan is connected between power supply by often driving temperature detect switch (TDS).
wherein, this device also comprises between closed type temperature detect switch (TDS) power supply and contactor.
wherein, this device also comprises that open type temperature detect switch (TDS) is connected between power supply and radiator fan.
Brief description of the drawings
fig. 1 is the utility model circuit diagram
Embodiment
as shown in Figure 1, highway LED street lamp or highway LED street lamp power system reactive power compensation embodiment have been provided.Whole device comprises air switch QS, contactor KM, reactor L, normally closed temperature detect switch (TDS) FR1, often opens temperature detect switch (TDS) FR2, radiator fan M.Air switch QS is the conventional common threephase switch in market, and break-make capacity is suitably chosen according to actual compensation capacity, and contactor KM suitably chooses according to actual compensation capacity; Reactor L capacity is according to the configuration of compensation requirement; Normally closed temperature detect switch (TDS) FR1 chooses according to reactor temperature-resistant material; Often open temperature detect switch (TDS) FR2 operating temperature and choose and must ensure will move before the action of normally closed temperature detect switch (TDS), otherwise radiator fan do not start, complete machine is not often worked; Fan M selects two ball bearing long-life blower fans; Temperature detect switch (TDS) is cemented in reactor line with thermal grease and wraps.
