Background technology
Quality of voltage all has a direct impact the stabilization of power grids and power equipment safety operation, line loss, industrial or agricultural safety in production and people's lives electricity consumption.China's electrical network due to by daily load, season load variations, radius of electricity supply, the impact of the factors such as power load distributing, often causes line voltage distribution to have a greater change, brownout can cause equipment undercapacity or work abnormal, and overtension can affect again the safety of power consumption equipment.Ensure that quality of voltage becomes a major issue.
At present, the method of conventional regulation voltage has two kinds: one changes the pressure regulation of main transformer of transformer substation load tap changer, the foundation regulated can only be take substation bus bar as benchmark, can not the voltage fluctuation of guarantee section circuit, and the safe operation impact of frequent adjustment main transformer tap on main transformer is larger; Another kind method is switched capacitor, and reached the object of pressure regulation by the pressure drop reduced caused by circuit reactive current, the method applicable surface is limited, range of regulation is little, is difficult to produce a desired effect.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of circuit automatic voltage regulator, automatic feeder line voltage regulator is utilized to carry out Voltage Cortrol to specific circuit, within the specific limits line voltage distribution is adjusted, ensure the supply power voltage of user, reduce the line loss of circuit.
For achieving the above object, the utility model provides following technical scheme: a kind of circuit automatic voltage regulator, it is characterized in that: described circuit automatic voltage regulator is by the single-circuit transformer with 9 taps, on-load voltage regulating switch and the automatic controller following the tracks of circuit terminal voltage with payload connect to form, single-circuit transformer is divided into main coil and voltage regulation coil, between voltage regulation coil every tap, voltage difference is 2.5%, total range of regulation is 20%, mains side main electrical scheme is switched to tap 9 from tap 1 by on-load voltage regulating switch, the range of regulation determination link that load side main electrical scheme needs according to user.
Preferably, described voltage regulator load side a, c phase install the inner differential of current transformer.
Preferably, described load side a, c phase install voltage transformer.
Preferably, described automatic controller is technical grade control chip.
Preferably, described circuit automatic voltage regulator has RS485 communication interface.
Adopt the beneficial effect of above technical scheme to be: 1, to extend electric substation's radius of electricity supply, be applicable to the long distance power delivery of rural power grids; Wide in region, in the electrical network of power load dispersion, remote power transmission is a difficult problem all the time, and newly-built electric substation is unreasonable economically, and Bu Jian transformer station power supply quality can not meet requirement again.Use line voltage distribution automatic regulator just well can solve problems, it can the power transmission distance of prolongation 10kV electric pressure at double, reduces line loss, improves the quality of voltage of power supply.2, whole piece circuit rate of qualified voltage can be made to reach 100%; According to route parameter calculation, installation site and the setting parameter of voltage regulator can be determined.By automatic voltage regulator self measurement circuitry voltage, after adjustment, guarantee that the voltage of whole piece circuit is up to state standards.3, the high and low value in voltage-regulation interval can set; Voltage regulation limits can be set by controller, and the high and low setting value of voltage can be revised at any time according to different load situation.4, line loss and distribution loss can effectively be reduced; By promoting circuit working voltage, exporting equal-wattage and can reduce the loss of running current reduction line power.Control circuit working voltage can reduce distribution loss and user power utilization equipment loss near rated value, extends power consumption equipment useful life.Own loss is extremely low.5, voltage regulator drop into or out of service need not power failure operation; The custom-designed combination by-pass switch of this matched with devices.Need not have a power failure during maintenance can be out of service by voltage regulator, also need not power failure operation when same voltage regulator puts into operation, improves power supply reliability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structure chart of a kind of circuit automatic voltage regulator of the utility model.
Embodiment
The preferred implementation of a kind of circuit automatic voltage regulator of the utility model is described in detail below in conjunction with accompanying drawing.
