1, high pressure distribution ark is used in power system, power generation, transmission, distribution, conversion and energy consumption on and off, control or protection role, voltage grade 3. 6 kv ~ 550 kv electrical products, mainly including the high voltage circuit breaker, high-voltage isolating switch and earth switch, high voltage load switch, high pressure automatic reclosing and section, high pressure operating mechanism, high voltage explosion-proof devices and high voltage switch cabinet and so on several broad categories. And that shu, the electrical think high voltage switch manufacturing is an important part of power transmission and transformation equipment manufacturing, occupies very important position in the whole electric power industry. But to do well the following 'five prevention' 1, high voltage vacuum circuit breaker in power distribution cabinet car in the test position after closing, the car circuit breaker cannot enter working position. ( To prevent false points or circuit breaker) 2, high pressure distribution ark grounding knife, in close out the car circuit breaker closing. ( Prevent with grounding line closing) 3, high voltage vacuum circuit breaker in power distribution cabinet in closing work, on the back door with grounding knife plate ark of mechanical and cupboard door lock. ( Prevent straying into charged interval) 。 4, high pressure distribution ark of vacuum circuit breaker closing at work, or grounding knife can't input. ( Prevent charged hanging earthing line) 5, high pressure distribution ark of vacuum circuit breaker closing operation at work, unable to exit the car circuit breaker working position. ( Prevent loading breaker) 2, high-voltage switchgear is used in power system, power generation, transmission, distribution, conversion and energy consumption on and off, control or protection role, high voltage switchgear according to voltage class in 3. 6 kv ~ 550 kv electrical products, and auspicious tai electric think high-voltage disconnector and earthing switch, high voltage load switch, high pressure automatic reclosing and section, high pressure operating mechanism, high voltage explosion-proof devices and high voltage switch cabinet and so on several broad categories. It using the environment below 1, installation height not more than 2, 1000 meters above sea level, ambient medium temperature is not higher than + 40 degrees, not below - 20 degrees 3, indoor relative humidity is not more than 85% 4, no conductive dust and can destroy the metal and insulation of the place 5, there is no danger of the gas explosion place 6, no violent vibration and turbulence, and the vertical Angle of not more than 5 degrees
