Sf6 Circuit Breaker

DAYA Sf6 Circuit Breaker Details

SF 6 circuit breakers mainly consist of two parts, namely (a) the interrupter unit and (b) the gas system. Interrupter Unit – This unit consists of moving and fixed contacts comprising a set of current-carrying parts and an arcing probe. It is connected to the SF 6 gas reservoir.

Substation equipment often costs millions of dollars and the reliability and safety of these assets largely depend on power circuit breakers. When a circuit breaker fails, it can damage surrounding equipment, contributing to costly outages and the endangerment of lives. To meet today’s crticial demands Mitsubishi Electric High Voltage Dead-Tank Power Circuit Breakers cover a range of 72.5kV to 800kV with interrupting classes spanning 40kA to 80kA.

DAYA Sf6 Circuit Breaker  Conditions for normal operating environment:

Beyond their primary function of protection, high voltage circuit breakers often are highly customized and engineered solutions. They have varying designs, with extensive maintenance and operating expense implications.

DAYA Sf6 Circuit Breaker  Processing characteristics

1. Cabinet part: all right-angled parts that operators may come into contact with are all reversed at R angles to prevent scratching and hurting people; the improved busbar frame is more convenient to install busbars and has a more beautiful appearance; the ventilation grid installed on the top cover has anti- Drip function; the top cover is an open structure, which is convenient for users to place horizontal busbars on site;

2. Drawer part: the drawer adopts double-folding positioning groove rivet riveting process, and all parts are molded at one time, so that the drawer is 100% interchangeable. At the same time, the double-folding and rivet technology solves the defects of sheet burr and self-tapping screw tip injury;

3. Connectors: The first-time plug-in for the incoming and outgoing lines of the drawer can be directly used in conjunction with the function board and the metal channel, and the secondary connector is convenient to connect and the wiring is beautiful;

4. Vertical channel: half functional board or iron rectangular channel can be selected, and can be easily interchanged.
