a) Ambient air temperature shall not exceed +40oC, the lower limit; -25oC,
b) The altitude is not more than 2000M
c) humidity; The daily mean value of relative humidity is less than 95% and the monthly mean value is less than 90%. The average daily vapor pressure is not more than 2. 2KPA, monthly mean not greater than 1.8KPA
d) The surrounding air should not be significantly polluted by corrosive or flammable gases and water vapor
e) No regular strenuous exercise
f) When the contactor is running, the dip Angle between the installation plane and the horizontal shall not be greater than 5o
g) Beyond the requirements of the above conditions, the user and the manufacturer shall agree.
Normally transported circuit breakers should be maintained regularly to remove the dust on the surface of the insulating parts, and the vacuum degree of the Indoor Medium Voltage Fixed Vacuum Circuit Breaker extinguisher chamber should be checked by the power frequency voltage resistance method. Users should not arbitrarily change the use of electrical components inconsistent with the original model. Operators should have a preliminary understanding of circuit breaker performance and basic knowledge of installation, adjustment and maintenance, record the problems in operation, notify the manufacturer if necessary, and send personnel to help solve the problems.
