Fixed High Voltage Switchgear Use features: anti-error type switchgear for 3.6 and 10 kV AC system for the acceptance and distribution of electric energy, low voltage to use, with features to prevent misuse in five: to prevent wrong meta-, misclassification error breaker; to prevent on-load points, co-isolation switch; prevent mistakenly charged interval; antistatic wire hanging is; to prevent closing with ground. Rated current: 3000A The following current types: three-phase AC 50Hz main bus types: single-bus, single-parent environment beside the bus plus 1, the installation height does not exceed an altitude of 1000 m 2, ambient temperature is not higher than +40 degrees, not less than -20 degrees 3, the indoor relative humidity less than 85% 4, no conductive dust can damage the metal and insulation gas and place 5, there is no danger of explosion places 6, no severe vibration and bumps, and the vertical gradient of not more than 5 degrees The super-power transformer economic operation in ensuring the safe operation of the transformer and meet the basic user power quality and reliability, the low voltage switch agent manufacturers and take advantage of substation equipment conditions, select the preferred mode of operation the transformer, reducing the transformer itself energy consumption, low voltage of the sales price, increase its supply side power factor, low voltage Lhasa, to achieve the goal of reducing energy loss. Power supply load and transformer capacity and determine the number of units, related to the transformer economic operation mode; the implementation of the transformer economic operation of the substation transformer station number, capacity and transformer own performance and loss parameters are closely related, it is built in to ensure safe and reliable power supply premise A comprehensive economic and technical activities, through the power transformer accessible from the design selection, running the entire decommissioning process; in the substation construction, expansion and transformer capacity increase is necessary to consider their associated factors and conditions; the implementation of transformer economic operation, the transformer and substation equipment itself and in general should have the following conditions are met transformer design and selection should be given full consideration. Low voltage switch price, Xi Connaught Electrical and Mechanical (certified), Lhasa low voltage provided by the Henan learning Connaught Electrical and Mechanical Equipment Co. Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) is Zhengzhou, electronics, electrical products processing leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
