Detailed Product Description: | High Voltage Switchgear main points of fixed and withdrawable type two; as regards the structure was divided into open, semi-enclosed, closed; inner have on the environment in terms of indoor and outdoor points; it has a mode of operation in terms of electromagnetic operating mechanism, spring-operated mechanism and a manual operator. Selection of high voltage switchgear, the decision to use the environment within the selected user type or outdoor type according to the switchgear according to the number and amount of reliability requirements were determined using fixed or withdrawable switchgear. Fixed switchgear prices cheaper, but not as flexible as withdrawable. High reliability requirements, however, the number of switch counter and fewer substations, try to use fixed switchgear to reduce investment. To determine the combination of high switchgear wiring design of a program, a program can be found in the relevant switchgear electrical manuals. Combined with control, metering, protection, signal and other requirements, select or design their own secondary wiring. After you have selected the main components of the switchgear cabinet according to conditions (altitude, ambient temperature, relative humidity, sunshine, wind speed, daily temperature, etc.) and short-verified. When the operating mechanism is selected, in conjunction with the power substations operating conditions. There DC operating power (silicon rectifier, batteries, etc.) to maximize the use of the electromagnetic operating mechanism. Small substations with manual operating mechanism is relatively simple, low voltage switch on the block, but the switching cabinet off the flow to weaken a lot. When ordering information should be provided by the manufacturer of high voltage switchgear in general are: 1. High Voltage Switchgear model, a line protocol number, substation secondary wiring diagram and operating mechanism is equipped with a 2. High Voltage Switchgear floorplan 3. High voltage Secondary switchgear wiring diagrams and terminal diagrams; when secondary wiring standard atlases program selected program number and should indicate the voltage control circuit 4 when ordering whether cabinet variable device and indicate current Variable ratio transformer 5. The need to use non-standard one or two line program or commissioned manufacturers design, in consultation with the manufacturers MCB SZRB2-125SZRB2-125 series MCB for AC 50 or 60Hz , low voltage, rated voltage 400V and single-phase 230V, Gongyi low voltage, rated current 125A and below the line, buildings and electrical equipment used to short-circuit, overload protection, can also be under normal circumstances as infrequent line conversion, but also to isolate the switch and as a line-voltage protection and long way off. The product appearance, small size, light weight, power trip setting precise, reliable action, high breaking capacity, tripping quickly, rail, combined mode design with auxiliary contacts, alarm indication contacts, undervoltage release , shunt trip accessory combination, to meet the needs of different users, the housing and components of high fire-retardant and impact-resistant plastic, long service life. This product complies with IEC60947-2 and GB14048.2 standards. Kaifeng low voltage, low voltage, provided by the Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co. Connaught. Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) strong, credible, in Zhengzhou, Henan electronics, electrical products processing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Connaught Electrical and Mechanical study into the brilliant and you work for a better future! |
