Introduction:
As one of the crucial devices in power systems, photocells play a vital role in controlling and protecting circuits.
However, not all power systems face the same challenges. Some regions require photocells with higher specifications, such as 20KV/10KA, to ensure safe and stable operation.
This article will explore the circumstances under which photocells need these parameters, with a particular focus on the unique requirements of lighting fixtures in certain areas.
It also explains why Zhejiang Leadtop Electric specially designed the LT134 photocell with a 20KV/10KA option for bidding projects.
The Necessity of Photocells with 20KV/10KA Parameters:
Characteristics of Regional Power Grids:
In industrialized or power-intensive areas, power systems may experience heavier loads, necessitating photocells with higher voltage and current capacity.
Additionally, these areas often feature long-distance high-voltage transmission lines, requiring photocells to meet the demands of such unique environments.
High Voltage and High Current Working Environments:
The presence of high-voltage transmission lines and large currents is a primary reason for needing photocells with 20KV/10KA parameters.
In such environments, power systems are susceptible to higher voltage and current fluctuations, necessitating photocells with greater protective capabilities to ensure safe operation.
Special Climate Conditions and Natural Disasters:
Some regions are prone to frequent lightning activity or are affected by climate conditions like summer monsoons, making power systems more susceptible to lightning strikes or high winds.
In these cases, photocells equipped with 20KV/10KA parameters can offer better overvoltage and overcurrent protection, effectively reducing damage from lightning and other natural disasters.
Increased Requirements for Power System Reliability:
Critical facilities such as medical centers and financial hubs require high reliability from their power systems, with low tolerance for power outages.
In such scenarios, photocells with 20KV/10KA parameters can provide a higher level of protection, ensuring stable power supply unaffected by external factors.
Special Requirements of Certain Lighting Fixture Types:
In some regions, traditional lighting fixtures like high-pressure sodium lamps are still prevalent. These lamps, which utilize gas discharge bulb technology, require high starting voltage and current during operation, with significant current fluctuations.
Without photocells equipped with corresponding parameters, power systems may become unstable, leading to fixture overload, short circuits, or even safety hazards.
Photocells with 20KV/10KA parameters can effectively address these issues by providing higher levels of overvoltage and overcurrent protection, ensuring the stability and safety of power systems during lighting operation.
Therefore, in regions where traditional lighting fixtures are common, photocells with 20KV/10KA parameters are essential for ensuring the normal operation of power systems.
Understanding and analyzing the requirements of these special lighting fixture types highlight the importance of photocells with 20KV/10KA parameters, providing necessary safeguards for the stability and safety of power systems.
Conclusion:
When facing the specific demands of regional power systems, photocells need to be equipped with 20KV/10KA parameters to ensure their safe and stable operation. By understanding these unique environmental requirements and challenges, we can better select and configure photocells, thereby enhancing the reliability and stability of power systems.
Zhejiang Lingtuo Electric’s LT134 is a customized photocell that not only supports 20KV/10KA parameters but also offers customization options for other product parameters, logos, and packaging according to customer needs.
