Abstract
The utility model relates to a modified tone balancing unit is joined in marriage to intelligence, contains signal acquisition element, the microcomputer control ware, IGBT drive circuit, the IGBT unit, moulded case circuit breaker, capacitor unit, this device is installed on the distribution transformer next door, each looks power load electric current condition of signal acquisition element real -time detection, and calculate through inside data processing center (DSP), draw out load current's composition, then pass through PWM signal control IGBT drive circuit, pass through the IGBT module according to the load condition who records from the less confession ferroelectric phase absorbed energy of load and supply with the great confession ferroelectric phase of load, thereby make in the power supply line three phase loads unanimous, but furthest performance power supply line efficiency.
Description
(1), technical field: the utility model relates to a kind of low-voltage power transmission line field, particularly the intelligent distribution transforming Balame regulating device of one.
(2), background technology: in the city dweller and rural power grids electric power system of low voltage three-phase four-wire system, because electricity consumer mostly is single-phase load or single-phase mixed with three-phase load, and payload is different and the difference of electricity consumption time.So three alternate unsymmetrical currents are objective reality in electrical network, and this electricity consumption unbalance condition irregularities, also cannot predict in advance, result in the secular disequilibrium of low-voltage power supply system threephase load; For three phase unbalance current, power department is except the solution that as far as possible reasonably almost has nothing effective except distribution load.
(3), utility model content:
The technical problems to be solved in the utility model is: not enough for prior art, provides a kind of intelligent distribution transforming Balame regulating device.
The technical solution of the utility model:
A kind of intelligent distribution transforming Balame regulating device, containing signal gathering unit, microcomputerized controller, IGBT drive circuit, IGBT unit, breaker of plastic casing, capacitor unit, containing the current transformer be located on transmission line in signal gathering unit, current transformer output is connected with the input of the analog to digital conversion circuit of microcomputerized controller, on transmission line, three-phase and four-line voltage is connected with the input of the analog to digital conversion circuit of microcomputerized controller, mould is at number conversion inside circuit, after the current signal on circuit and voltage signal calculation process, again digital quantity is delivered to data processing centre, data processing centre is to the supercomputing of analog to digital conversion circuit digital quantity, result of calculation is given pwm signal circuit, pwm signal circuit output end is connected with IGBT drive circuit input, IGBT unit controls input is connected with IGBT drive circuit output, breaker of plastic casing input is connected with three phase mains A phase, B phase, C respectively, breaker of plastic casing output is connected with series reactor input, series reactor output is connected with IGBT unit input, breaker of plastic casing is also connected with capacitor unit input, and capacitor unit output is connected with the zero line N of power supply.
Operation principle: this device is arranged on distribution transformer side, signal gathering unit detects each phase electric load current conditions in real time, and calculated by internal data processing center (DSP), extract the composition of load current, then IGBT drive circuit is controlled by pwm signal, absorb energy according to the load condition recorded mutually from the power supply that load is less and supply the larger power supply phase of load by IGBT module, thus make supply line one side three-phase load consistent, supply line's efficiency can be played to greatest extent.
The beneficial effects of the utility model:
1. balance distribution transforming and export three-phase current, voltage, reduce zero-sequence current;
2. reduce distribution transformer loss, line loss, energy-saving and emission-reduction, improve Utilities Electric Co.'s economic benefit;
3. improve transformer capacity utilance and power output.Prevent because one-phase overload causes transformer to burn, improve transformer useful life, ensure Electrical Safety;
4. prevent neutral point drifting, the neutral line burns; Balanced voltage, prevents overtension and jeopardizes the power consumption equipment of resident.
