Description
Technical field
The utility model discloses a kind of high tension distribution system wattless automatic control device, can be widely used in distribution system and use electric unit, regulate the reactive power of distribution system, improve power supply quality and saves energy, and use as power transformer.
Background technology
At present, the distribution system device that is used for idle automatic control mainly contains two kinds.A kind of is automatic switching capacitor group VQC, promptly capacitor is divided into some groups, inserts the load bus with high voltage connector or circuit breaker respectively, reaches the manual or automatic switching capacitor group with load variations.Another kind is the voltage-regulation type reactive power automatic compensation device, and promptly capacitor is fixing inserts, and regulates idle output by the terminal voltage of voltage regulator regulating capacitor, reaches idle in-situ balancing.Distribution system and be two relatively independent separately complete equipments with the transformer and the idle control device of electric unit, distribution system and during with the newly-increased transformer of electric unit, transformer not only will buy power, also need to purchase new idle control device according to transformer capacity, will corresponding increase equipment investment, be unfavorable for economical operation.
The utility model content
The utility model is to utilize the principle of the principle of voltage-regulation type reactive power automatic compensation device and power transformer and design feature and make a kind of high tension distribution system wattless automatic control device.This device not only can be realized idle automatic timely compensation in distribution system, reaches reduction line loss, improves power factor and supply power voltage quality, and can be used as the power transformer use, for power consumer has been saved great amount of investment.
Take following technical scheme for realizing the purpose of this utility model:
Make a kind of high tension distribution system wattless automatic control device, this device contains a current transformer 1, voltage transformer 2, microcomputerized controller 3, the control system that tap changer for three phases 4 is formed; Voltage regulator 5, the reactive compensation system that on-load switch 6, a group capacitor 7 are formed; The electric power system that voltage regulator 5, load 8 are formed connects together control system, reactive compensation system, electric power system and makes the high tension distribution system wattless automatic control device.
The used voltage regulator 5 of the utility model is the special transformers with ten binding posts, and the former limit of this special transformer is divided into A, B, C, and secondary is a1, b1, c1 and a2, b2, c2, n; Secondary a1, b1, c1 and former limit A, B, C utilize the public one group of iron core of the principle of autotransformer and on-load switch 6, capacitor 7 to form reactive compensation system; Secondary a2, b2, c2, n and former limit A, B, C have constituted general power transformer and electric power system is formed in load 8.
The utility model is made a set of equipment with idle control device and power transformer, has both utilized the advantage of voltage-regulation type reactive power automatic compensation device, has really realized idle automatic timely compensation; Saved the expense of the transformer that buys power separately again, for power consumer has been saved great amount of investment.
Description of drawings
Further the utility model is described below in conjunction with accompanying drawing.
Fig. 1: theory structure schematic diagram of the present utility model;
Fig. 2: the internal circuit configuration schematic diagram of voltage regulator 5 among Fig. 1;
Fig. 3: the external structure vertical view of voltage regulator 5 among Fig. 1
Among the figure: 1, current transformer 2, voltage transformer 3, microcomputerized controller 4, tap changer for three phases 5, voltage regulator 6, on-load switch 7, capacitor 8, load
Embodiment
As shown in drawings among the figure 1 be current transformer, 2 for voltage transformer, 3 for microcomputerized controller, 4 for tap changer for three phases, it is connected together forms control system of the present utility model.The b that a phase current signal that current transformer 1 is gathered and voltage transformer 2 are gathered, c phase voltage signal insert microcomputerized controller 3 through cable, microcomputerized controller 3 calculates natural power factor, according to the power factor upper limit value and lower limit value that sets, send instruction for tap changer for three phases 4, finish upgrading or lower category process.Shunting switch 4 is contained in voltage regulator 5 inside and links to each other with secondary a1, the b1 of voltage regulator 5, the tap of c1, and secondary a1, the b1 of voltage regulator 5, c1 and on-load switch 6, capacitor 7 are connected to form reactive compensation system.When shunting switch 4 upgraded or lowers category according to instruction, the terminal voltage that is added in capacitor 7 was along with raising or reducing, according to Q=2 ∏ fcu
2Principle, the idle output of capacitor 7 also will raise or reduce.Shunting switch 4 has nine gears, if this moment, power factor still can not meet the demands, microcomputerized controller 3 can send the instruction of transferring the files for once more shunting switch 4, till power factor can satisfy system requirements.Secondary a2, the b2 of voltage regulator 5, c2, n and the load 8 composition electric power system that connects together.
Used current transformer 1, voltage transformer 2, microcomputerized controller 3, tap changer for three phases 4, on-load switch 6 and the capacitor 7 of the utility model is at the market existing procucts, only needs to get final product by principle wiring shown in Figure 1 by model purchase and voltage regulator 5.
