What are the advantages of high-voltage branch boxes?
With the continuous popularization and development of electrical safety in modern times, people's safety awareness has begun to improve. As a result, many products have emerged that prioritize the protection of people's safety. Currently, high-voltage transmission and distribution are very common in many areas, which poses certain safety hazards. The emergence of high-voltage branch boxes has effectively solved this problem. So, what are the advantages of high-voltage branch boxes?
1. Diverse transmission methods
In the online monitoring system of cable branch boxes, the temperature of the joints is transmitted reliably and wirelessly through a belt-type temperature sensor, while short-circuit current information is transmitted via fiber optics using short-circuit current sensors.
2. High degree of intelligence
The detection of cable joint temperature and fault information in high-voltage branch boxes has achieved online non-invasive detection technology. Each sensor node on the high-voltage side is reliably electrically isolated from the MCU on the low-voltage side, overcoming interference from strong electric fields and strong electromagnetic radiation inside the box. Once voltage leakage, line faults, or live status information occurs, it will automatically conduct remote online monitoring and fault alarms.
3. Good waterproof performance
From the outgoing line to the electrical load, a main large cable is often used for the outgoing line, and then, close to the load, a cable branch box is used to divide the main cable into several smaller cross-sectional area cables, which connect to the load. The cable holes, reserved holes, and gaps at the bottom of the branch box are the main channels for water vapor to enter the box. As long as effective sealing is performed, the entry of water vapor can be reduced.
In addition, the improvement of acceptance standards for branch boxes can be analyzed from the following aspects. The installation procedure must be strictly controlled, and the integrity of the branch box should be carefully checked during installation to see if its operating indicators meet the standards. The methods of power supply operation and the amount of power supply load should be carefully assessed, and the occurrence of breakage should be avoided.
As an important protective device, high-voltage branch boxes with guaranteed quality play a very important role during use. This product better ensures people's safety while also reducing safety issues related to life and property caused by high-voltage leakage.
