Nader Circuit Breaker

When the circuit breaker with a circuit breaking current, the movable, stationary arcing contacts separate. With the downward movement of the rod movable contact, an arc extinguishing chamber sequentially drawn human oil bag in contact with the oil, the oil evaporation, high pressure oil is decompose...

SF6 circuit breaker is typically using several dozen to atmospheric pressure SF6 gas, a high velocity air stream in the spout to extinguish the arc. Recommended storage using a predetermined high-pressure sulfur hexafluoride gas circuit breaker, is formed in the high velocity gas stream is strongly h...

Vacuum circuit breaker is a vacuum (a vacuum degree of 10-4mm Hg or less) with good arc-proof insulating properties and performance characteristics, the part of the circuit breaker contacts mounted within the housing and a vacuum circuit breaker made. Vacuum circuit breaker having a small size, light...

Common circuit breakers are commonly used for the AC circuit and off, whether for a direct current, DC current key is the ability to cut. For alternating current, while the breaking of the contacts, an arc will be generated, i.e., a so-called "arcing." However, the characteristics of the alternating ...

The oil in the oil-rich circuit breaker and the oil-less circuit breaker have the same function (both transformer oil), which is mainly used for insulation and arc extinguishing. If it is mainly used for insulation and heat dissipation in the transformer. Both oil-rich and oil-less circuit breakers m...

In order to improve its breaking capacity, the oil circuit breaker is equipped with an arc extinguishing chamber made of insulating material around the contacts. The arc extinguishing chamber of the oil circuit breaker uses the gas generated by the decomposition of the oil to form a high-speed airflo...

The function of high-voltage circuit breaker is embodied in two aspects of control and protection. The first is the control function, which controls the use or withdrawal of electrical equipment and the operation of the line based on the actual operation needs of the power grid; the second is the pro...

Vacuum circuit breakers use vacuum as the arc extinguishing medium. The pressure in the arc extinguishing chamber under high vacuum is very low (only 1.310-4～1.310-5 Pa), only a few gas molecules exist, the insulation strength between the electrodes is high, and there is fast insulation Intensity r...

Circuit breakers are widely used in electrical panel cabinets and instrument panel cabinets. Familiar with the normal use conditions and installation conditions of circuit breakers is of great significance to improving the reliability and safety of electrical and automatic systems. This article provi...

1. Internal structure If the 4 rivets are damaged, you can split them in half, as shown in the figure below. The parts are embedded in the left cover, and the right cover can be removed. 2. Circuit part When the contact is closed, the circuit path is (set the direction from top to bottom): 1-2-3-5-6-...
