In the control technology of power networks, components such as contactors and disconnect switches (DCs) are widely used due to their characteristics. However, with the development of power control technology, new materials and technology have been applied in the design and production of disconnect switches, and new disconnect switches such as H12-03R have emerged. This article will discuss the application field and working principle of H12-03R disconnect switch.

Application field of H12-03R disconnect switch

H12-03R disconnect switch is specially designed for disconnection in high-voltage switchgear. The disconnect switch can interrupt current and voltage under the rated breaking current, which can make the high-voltage switchgear easier to operate and maintain. In addition, the disconnect switch also plays a role in the safe isolation of high-voltage switchgear. In some complex network environments, due to the limited space, the installation of a disconnect switch can save a lot of space. As a result, the installation of the disconnect switch has become an important part of the power distribution network.

Working principle of H12-03R disconnect switch

H12-03R disconnect switch adopts exchange trip breaking technique, which can quickly break off the circuit when the current or voltage of the circuit exceeds the rated value. The disconnect switch applies a certain mechanical force to the main contact of the switchgear, and the mechanical force is converted into electrical current through a casting material, which activates the voltage circuit of the switchgear structure. The operation of the voltage circuit causes the driving lever to move downward, driving the closing or disconnection of the main contact. During the disconnection process, if the current or voltage of the circuit exceeds the breaking current of the switch, a certain air gap will be generated between the main contact and the arcing contact due to the electromagnetic force generated by the current and the attractive force generated by the arc, so that the circuit is disconnected.

Conclusion

In summary, H12-03R disconnect switch has many advantages such as small size, strong breaking capacity, simple structure, making it suitable for installation in high-voltage switchgear for current interruption and voltage isolation, and the road conversion breaking technique makes it have better breaking performance in various network environments. Thus, H12-03R disconnect switches have been widely used in switchgear applications.
