Precise SF6 Gas Load Break Switch (24KV SF6 LBS)

SF6 Gas Load Break Switch (LBS)

PRECISE’s Load Break Switch was designed in compliance with IEC 60265 1 (1988) and IEC 60694 (2001) The product has been
extensively perform tested by CESI from ITALY. The tank of LBS is made from high-grade stainless steel with 3.0 mm. thickness.
Thus corrosion-resistant and installation outdoor type. The tank has also been robotically welded, leakage-tested by VS LEAK
DETECTOR and filled with SF6 gas For arc extinguishing. Degree of protection for LBS Gas tank is IP67 and IP54 for control box.

Load Break Switch is an electric circuit breaker in high-voltage, be able to on-off with load connected by contact in puffer
type cylinder. The contact element is two, Stationary and Moving contact. The puffer will be contained in tank with SF6 for
arc extinguishing. Spring toggle is using for contact driving, by manual operation with handle or remote operation with
mechanism driving motor.

LBS has two main safety devices

Low-pressure lockout :When the SF6 gas is below the specified level the LBS will can’t operate. Because when SF6 gas low, capability for arc extinguished will lower. The low-pressure lockout thus helps Prevent damage that might be caused to the user, the device and the quality of the electrical system.

Over-pressure release device :In case of any overpressure condition, a rapture disc (or the Over-pressure release device)
will break down and thus release pressure inside the LBS. To prevent an explosion or swelling of the body LBS cause less damage.
