Vacuum interrupter voltage is sophisticated


The insulation performance of the vacuum gap is not only affected by the performance of the contact material, but also by the contact surface conditions such as micro-bumps, attached metal particles, oxides and organic contaminants, and surface gas content. Accurate voltage can effectively improve the Vauum interrupter contactor contact between the withstand voltage strength. The finely polished electrode is much smoother than the voltage-trained surface, but the withstand voltage is not as good as the post-electrode electrode gap.


For the new production of the vacuum interrupter, the frequency of the spark under the sophistication is the most simple and most effective way to improve the vacuum interrupter. The voltage is experienced mainly by the use of gap breakdown of the discharge energy of the electrode surface layer of local melting and crystallization, so that the vacuum gap with the intensity of the breakdown with the breakdown and gradually increased. Therefore, the appropriate change in sophisticated discharge energy can effectively speed up the process of sophistication.

Insulation of vacuum interrupter

Vacuum circuit breaker insulation is divided into fracture insulation, interphase insulation and insulation to the ground. vacuum interrupter in the vacuum circuit breaker in addition to breaking the working current and short circuit current, but also bear the task of fracture isolation. At present, the manufacturer of interrupter is good and bad, in order to ensure the vacuum circuit breaker in the safe and reliable operation of the power system, vacuum interrupter as the core of the vacuum circuit breaker device to ensure its insulation capacity, select the quality assurance manufacturers is essential The Vauum interrupter contactor insulation is divided into internal insulation and external insulation, the internal insulation is divided into static insulation and dynamic insulation. In the type test, the insulation of the vacuum interrupter mainly assess the short-time power frequency withstand voltage and lightning impulse withstand voltage, and in actual use, due to grid conditi...

What is the effect of the arc extinguishing device?

Is to pull the arc, sub-section, Vauum interrupter contactor device is to prevent the contact when the arc spark caused by unnecessary losses caused by the set. In a high current circuit, the contact or switch off and forth will produce arc spark, may cause the following hazards: 1, burn contact contacts, etc., over time so that the circuit is bad, resulting in circuit damage. 2, may be on the human eye, skin and other arc burns caused by the human body can not be speculation of the harm.   3, in some places sensitive to arc spark, such as gas plant or filling the flammable gas where a little bit of the spark sparks may cause an explosion and so on. 4, the spark sparks may be with the circuit for some electronic products (such as integrated circuits) caused by breakdown damage. So for safety reasons, in a large current may cause contact contacts and other places have to install a metal box to shield the spark sparks, vacuum interrupter is the most common.

What is the role of the glass enclosure of the vacuum interrupter?

Arc is actually the shape of the current in the air, in the final analysis, or the current, the conductivity of the metal is good, of course, can attract current, so the arc ran to the metal grid, the arc energy, of course, can burn metal grating, so the energy of the arc Not on the consumption of it, like Dayu flood control, not to be out is not possible, the key is to ease the arc burning bar that it will not burn the contact, so only for the arc chamber breaker Can be reused. Part of the main screen shield and bellows shield, generally use oxygen-free copper or stainless steel main effect: 1) to prevent the contact in the arcing process to produce a large number of metal vapor and droplet splashing, pollution of the inner wall of the insulating shell, to avoid causing the vacuum interrupter shell insulation strength decreased or flashover. Bellows shield is mainly to protect the bellows from the corrosion of metal vapor and lead to leakage, and now some of the desi...
