| Vacuum circuit breaker and X-ray
Pressure of 36kV. Because the load voltage is less than the 50kV,asics running shoes, failed to detect the radiation produced, and for the 27kV and 38kV vacuum switch requires the design of test voltage is 60kV and 80kV, the voltage level sufficient to produce X-rays can be measured. As a routine part of the installation and maintenance procedures, the high voltage test site design rated test voltage is usually taken 75%. The voltage level sufficient to confirm that the insulation system in good condition,ugg boots günstig, but Buzhi Yu damage insulation. Table 1 Voltage and 3m outside the X-ray detection of the relationship between the normal operation of the vacuum switch, design test and field test voltage and 3m outside the X-ray detection of the level of Table l. Safety testing procedures one by one G 3 SAFETY TECHNOLOGY 4 (No. 8 of 2002) there are many precautions to ensure safety and to avoid x-ray exposure, the most important preventive measure is to maintain a safe distance during high-pressure test. The intensity of X-ray and-ray source with increasing distance was significantly decreased, so test, test personnel to stand farther away from the vacuum switch by the lower levels of irradiation. To avoid electric shock, this test personnel (including factory and field within the staff) in their daily trials and testing of any pressure to keep a few meters distance from the object. Eaton Corporation (Cleveland, Ohio) rule of thumb is to test the switch for at least 3m distance. In the distance, the test voltage of 50kV is not detected within the X-ray, far away in the ANSI test voltage of 50kV or more within the limits set. Test voltage of 50kV or more, absorption of X-ray shielding material, such as steel or lead, can be used as an additional protective layer to protect the employees. For example, the new vacuum switch of the conventional product testing, the use of the shield allows the operator close to the shell without any risk of irradiation. The whole time at the factory, where the vacuum switch in the voltage of 50kV and above tests several times a day, then another security measures can be taken one by one film-style-ray dosimeter. Eaton,moncler jacken, New York Horseheads vacuum switch factory, and all study personnel and other persons near the test area are wearing dosimeter, monthly check of the accumulation of radioactive irradiation, the use of such methods to monitor the testing personnel subjected to X-ray irradiation conditions. If the irradiation to allow the limit to the alarm. In the Horseheads plant had never happened to test its employees in the product could be detected from the irradiation direction. Field test personnel to monitor X-ray irradiation is not required, because of low test voltage, test and test rarely carried out and to maintain a safe distance from objects of exposure levels sufficient to ensure the allowed range. (Translated from the editorial department ElectricalWorldT & DNov/Dec2001) Gold Power feast magazine organized the previous stage technologies electrical safety rules revisions prize solicitation activities now completed, this essay received a lot of (\good regulatory changes proposed, the effect is very large. According to the current situation of the country's new power system, power system is being steadily implemented. This is a big change, the power system security must also be new changes. With this new situation, to organize a new one journal special prize solicitation activities. To encourage grass-roots units, particularly small and medium power generation business,UGG ブーツ, Xiangongdianju, substations, rural power supply comrades to participate actively in the solicitation activities, special activities will be divided power essay and power generation 2 groups. 1 essay content (1) power system security management after the new ideas; (2) conversion process safety measures; (3) promote the construction of power production safety policies; (4) security theory and security technologies, research results; (5) Experience in safety management; (6) the status of implementation of safety and problems; (7) typical accident analysis, accident prevention measures; (  safety activities and safety team the public about the work. Award Ng i notice (3) legible, to provide qualified print out as much as possible; (4) articles marked \name, organization, address, postcode and telephone number. 3 incentives in the power supply and power generation two groups, respectively, Ping Chu: (1) first prize in a bonus 500.00; (2) Second Prize 2 , bonuses 300.00 yuan; (3) 5 third prize, bonus 200.00; (4) The award-winning essay and the essay meet the published standards will be published in the journal. 4 Awarding technical editing by the Ministry of Electricity Safety organize relevant experts to review.
