THLXD-ZM-0.38-30A Highway Intelligent Lighting Voltage Stabilization and Dimming Device

In the customization process of the THLXD-ZM-0.38-30A Highway Intelligent Lighting Voltage Stabilization and Dimming Device for AC street light conversion lighting voltage stabilizers, the phase sequence protection function is customized to enhance the system functionality of the AC power voltage regulation and stabilization device itself, thereby improving the phase sequence protection capability. This way, if the AC street light conversion lighting voltage stabilizer experiences a voltage error disconnection or output anomaly during operation, the phase sequence protection function will issue an alarm, promptly notifying maintenance personnel to perform repairs and maintenance on the device.

Compared to purely compensation-type devices, the advantages of the voltage stabilization regulation device are: since the thyristor network of the voltage stabilization regulation device is located on the output side of the compensation transformer and is further stepped down by an autotransformer, it not only reduces the thyristor switching voltage (from 220V to 200V or lower) but also suppresses the inrush current generated during switching (the autotransformer itself acts as a high-power reactor), thereby significantly improving the operational reliability and anti-interference capability of the thyristors.

Main Forms of Controller Winding Short-Circuit Faults

Under the electromagnetic forces of a controller short-circuit, winding damage and lead displacement are potential consequences. Both experimental research and operational practice indicate that the damage to controller windings under short-circuit electromagnetic forces mainly manifests in the following forms:

(1) Winding deformation causing turn insulation rupture, leading to inter-turn short circuits. This is the primary form of damage in small distribution controllers with smaller diameters under radial tensile electromagnetic forces during short circuits.

(2) Winding deformation reducing main insulation strength, resulting in main insulation breakdown. This is the main form of damage in medium-sized and larger power controller windings subjected to radial tensile short-circuit forces. Therefore, when designing the short-circuit strength of controller windings, the cumulative effect of residual deformation under electromagnetic forces must be considered.

(3) Radial instability of windings. Inner windings of controllers with iron cores or intermediate windings of multi-winding controllers may experience circumferential compression due to radial short-circuit electromagnetic forces under fault conditions. Radial instability in medium-sized and larger controller inner windings is a primary form of damage under radial short-circuit electromagnetic forces.

(4) Axial instability of windings. Axial instability is the main form of winding damage under the combined action of axial and radial short-circuit electromagnetic forces.

(5) Overall displacement and tilting of three-phase controller windings. This occurs under three-phase symmetrical short-circuit fault conditions.

Selection of Intelligent Lighting Energy-Saving Distribution Cabinets: 3.1 Energy-Saving Cabinet Capacity Selection. Assuming the energy-saving cabinet supplies power to 90 high-pressure sodium lamps (400W/lamp). According to the technical manual for standard high-pressure sodium lamps, the rated current for a 400W lamp is 4.6A. Total current per phase = 4.6A/lamp × 90 lamps ÷ 3 phases × 1.1 = 151.8A. The rated current of the energy-saving distribution cabinet should be greater than or equal to this current. Referring to the JCT distribution cabinet manual, a JCT-3100 Intelligent Lighting Energy-Saving Distribution Cabinet with a three-phase 100kVA capacity and a rated current of 152A per phase can be selected.
