The overall structure of the product box for three-phase, three-phase vacuum interrupter in a metal box, transformer reliable performance, high dielectric strength. This series actuator is spring energy storage, electric and manual is divided into two kinds. Circuit breaker in line GBl804, DL403, GBll022 and other standards, both in normal conditions or under fault conditions (especially short circuit), as long as the technical parameters of the circuit breaker, it can ensure the safe and reliable operation the corresponding voltage level of the grid. This product complies with the following main national standard: GB / T726-2000 "basic relays and devices: Switch part: GB1984" AC high voltage circuit breakers "GB / T11022-1999" high-voltage switchgear and control equipment standards common technical conditions "control terminal section Test method "GB / T17626-1998" EMC test and measurement techniques - Electrical fast transient burst out interference Test "Second, the use of environmental conditions 1, ambient air temperature: -40 ℃ ~ + 40 ℃; diurnal temperature: warm day change is not greater than 25 ℃; according to the material properties of SF6 gas, when the ambient temperature at -40 ℃, such as the internal pressure of the box 0.05Mpa, this time still SF6 gas, to ensure that products work properly. (When the ambient temperature is -40 ℃, when the gauge pressure of 0.05Mpa, SF6 liquefaction point of -55 ℃; zero gauge pressure, SF6 liquefaction point does not exceed -60 ℃). 2, the wind speed is not greater than 35m / s; 3, non-flammable, explosion, places a strong chemical corrosion (such as various acids, alkalis, or smoke, etc.) and intense vibration. 4, elevation: ≯1000m; 5, cover thickness: 10mm; 6, the degree of air contamination: IV level; 7, seismic intensity: ≯8 degrees; 8, neutral point grounding: ungrounded neutral point large_capacity grounded neutral point low resistance to ground.
