Vacuum Circuit Breaker With PT

DAYA Vacuum Circuit Breaker With PT  Details

Medium-voltage VCPW-HD vacuum circuit breakers The Eaton MV VCPW-HD Medium-Voltage Vacuum Breaker exceeds user expectations with unmatched reliability and space saving design. The VCPW-HD seal protects against dust and contaminants, and provides long-lasting equipment life.

What is VCB? VCB stands for Vacuum Circuit Breaker. In vacuum circuit breakers, the vacuum is used as the arc quenching medium. Vacuum offers the highest insulating strength. So it has far superior arc quenching properties than any other medium (oil in oil CB, SF6 in SF6 circuit breaker ).

DAYA GCK Low Voltage Vacuum Circuit Breaker With PT Working conditions

1) Its structure is 3 separate phase pillars, so that it will not cause short between phases if single phase is in fault

2) Vacuum arc-extinguishing chamber is in the isolated sleeves of each phase to avoid the short fault caused by dewing

3) The outside isolation material is imported outdoor epoxy resion or silicon rubber, which are with excellent hydrophobicity and anti-pollution, can be applied in the bad outside environment

4) It is with compact structure, small size, light weight and easy to be installed

5) No transformer oil or sulfur hexafluoride gas inside of the circuit breaker and can meet the requirements of non-oil upgrade and environment protection

DAYA Vacuum Circuit Breaker With PT Parameter (Specification)

acuum switching technology is the dominant switching principle in medium voltage.

Together with perfect function at the selected ratings, the compactness of these components is especially decisive, as they determine the overall size of the whole switching device. Embedding the vacuum interrupters in a special cast resin makes the pole parts of the circuit-breaker notably robust and at the same time protects the ABB vacuum interrupters from impact, dust, moisture and external damage. There is currently no more effective form of protection..

DAYA Vacuum Circuit Breaker With PT 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.
