Electricity solar street light sense of national standard units participated in ballast shortcomings

The shortcoming of inductance ballast 1, low power factor, loss is big, with power grid pollution; 2, input voltage range is small, low power, it is hard to start the startup time long; 3, the system itself has no voltage/power measures, destabilize brightness; 4, lead to lower power factor distribution change



the inductance ballasts The inductance ballast, 电感镇流器) Is a core inductance coil, inductance is the nature of the when the current in the coil change, will cause the change of the magnetic flux in coil, thus produce inductive electromotive force, the direction and the change of the current in the opposite direction, thus hindering the current changes. 】 The disadvantages of the

1, low power factor, loss is big, there are power grid pollution;

2, input voltage range is small, low power, it is hard to start the startup time long;

3, the system itself has no voltage/power measures, destabilize brightness;

4, lower power factor in power distribution transformer Distribution transformer, hereinafter referred to as 'match', refers to the power distribution system according to the law of electromagnetic induction transform ac voltage and current in ac power and transmission of a static electrical appliances. 】 Increases and the capacity of the wiring, installation fees use high;

5, due to the iron chip in electromagnetic force under the action of earthquake six meters lamp price movement and noise;

6, heavy structure.
