Problems solved by technology

[0004] 1. Self-coupling step-down, this kind of step-down mostly uses fixed taps, the output voltage will fluctuate with the change of the input voltage, the flexibility is poor, and the step-down range is large, causing the street lights to flicker
[0005] 2. Continuous sliding voltage adjustment. This type of product is driven by a small motor to adjust the coil and output voltage at any time. This type of voltage adjustment has high precision, but the brush frequently slides, the service life is greatly shortened, and it is prone to failure

Abstract

A street-lamp intelligent matrix compensation type power saving device relates to the street lamp energy saving technology field. The device comprises a major loop circuit, a programmable controller, a power supply module used for providing power for each electric unit and a compensation transformer. An input terminal of the programmable controller is connected with a voltage transmitter and a temperature sensor. The voltage transmitter is connected with the major loop circuit. The voltage transmitter is used for collecting an output voltage of the major loop circuit. An output terminal of the programmable controller is connected with a thyristor output circuit and a touch screen. The thyristor output circuit is connected with a matrix-type multiple-tap transformer. The compensation transformer and the matrix-type multiple-tap transformer are connected in series. The programmable controller, the voltage transmitter and the temperature sensor collect voltages, currents and temperatures and carry out real-time monitoring so that normal and stable working of a system is guaranteed. Because of a human-machine interface, it is convenient for technology personnel to overhaul and check a technology parameter. Functions of fault alarm, recording, leading out, printing and the like are possessed.

Description

technical field [0001] The invention relates to the technical field of street lamp energy saving. Background technique [0002] At present, there are two main ways to save energy for street lamps: one is to use midnight lights, and the other is to use voltage regulation. Mid-night lights save energy by turning off part of the street lights in the second half of the night. It is simple and easy to implement. The disadvantage is that the road lighting is uneven, and it cannot solve the problem that the voltage rises in the second half of the night and the life of the lamps is shortened. [0003] There are currently several ways to adjust pressure: [0004] 1. Auto-coupling step-down, this type of step-down mostly uses fixed taps, the output voltage will fluctuate with the change of the input voltage, the flexibility is poor, and the step-down range is large, causing the street lights to flicker. [0005] 2. Continuous sliding voltage adjustment. This type of product is dr...
