THLXD-ZM-0.38-20A Highway Street Light Load Voltage Regulation and Control Device

THLXD-ZM-0.38-20A Highway Street Lamp Lighting Load Voltage Stabilization Control Device During the customization process of AC street lamp conversion lighting voltage stabilizers, the implementation of phase sequence error protection customization can enhance the system functionality of the AC power voltage regulation and stabilization device itself, improving phase sequence protection. This way, if the AC street lamp conversion lighting voltage stabilizer experiences voltage disconnection errors or output issues during operation, the phase sequence error protection function will issue an alarm, promptly notifying maintenance personnel to perform repairs and maintenance on the AC street lamp conversion lighting voltage stabilizer.

Compared to pure compensation types, the advantages of the voltage stabilization control device are: Since the thyristor network of the voltage stabilization control device is located on the output side of the compensation transformer and is further stepped down by an autotransformer, it not only reduces the switching voltage of the thyristor (from 220V to 200V or lower) but also suppresses the surge current generated during switching (the autotransformer itself acts as a high-power reactor). This significantly enhances the operational reliability and anti-interference capability of the thyristor.

Main Forms of Controller Winding Short-Circuit Faults

Under the electromagnetic force 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 for 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 for medium-sized and larger power controller windings under radial tensile short-circuit forces. Therefore, when designing controller winding short-circuit strength, the cumulative effect of residual deformation under short-circuit electromagnetic forces must be considered.

(3) Radial instability of windings. For windings placed inside the core or intermediate windings of multi-winding controllers, under short-circuit conditions, they may experience circumferential compression caused by radial short-circuit electromagnetic forces. Radial instability of inner windings in medium-sized and larger controllers is the 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 of standard high-pressure sodium lamps, the rated current of a 400W high-pressure sodium 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 three-phase 100kVA capacity and a rated current of 152A per phase can be selected.
