The products sum up ZW20-12B outdoor high-pressure vacuum circuit breaker (hereafter referred to as the circuit breaker) It is the nominal voltage 12kV, the outdoor switching equipment of the three-phase alternating current 50Hz. It adopts vaccum arc extinction and SF6 gas as insulating medium, is used mainly in the gap, Guan He 10kV electric system's load current and short circuit current, are suitable for the converting station and the power distribution system of the industrial and mining enterprises to use for protection and control, suitable for the occasion that the electric wire netting is frequently operated. The structural features container body of the products has adopted the gas which introduces Japanese Toshiba VSP5 to seal, unexplosive, the technology of insulation structure, passing in and out the line conduit carries on sealed performance improvement too, it is of good performance to seal wholly, SF6 gas of internal filling is not leaked, is free of external environment, its spring of actuating mechanism has carried on miniaturization design and reliability and stability optimization, adopt the initiative and multiple tripping system of link chain of direct action, the spring actuating mechanism of the movement reliability and stability with domestic and traditional sex ratio has improved several times: The contact between axle and set of the major loop has adopted the flanning type chain structure of table of adduction, the contact resistance of the major loop is small, temperature rise is low. ZW20-12B outdoor high-pressure vacuum circuit breaker has also increased overcurrent protection, organization's spring stored energy instruction, and allocate the aviation socket to do two-shot electrically connected, easily to combine with intelligent control device, fine electric and organization's characteristic, make this product widely used, the products accord with GB1984 standard, exchange circuit breaker GB/T1102, high-pressure switch apparatus and canonial share technical requirement of the control equipment under high pressure. Type meaningUse the height above sea level of the environmental condition: Less than 2000m; The air temperature around: -40° C- +40° C, Japan's temperature difference: The warm change of sun is not greater than 25& deg; C; Wind speed: Not greater than 35m/s; Have flammable, explosion hazard, strong the intersection of chemical corrosion and thing (sour such as various, alkali or smother,etc.) And the place shaken vigorously. Technical parameterInstall the size in ZW20-12B outdoor high-pressure vacuum circuit breaker appearanceInstall, maintain characteristic and installation adjustment that the operating personnel should understand the products tentatively, maintain knowledge, should record the question in operation, notify the manufacturer if necessary. The products need to carry on appearance inspection before installation. Observe insulating bushing of products have, damage, disintegration point out and stored energy instruct leak and install the phenomenon, it is out of shape that there are the container bodies,etc.. Check-off, products want, mount at the post above the high 4m using. The circuit breaker with disconnecting switch should check the reliability of mechanical interlock movement between disconnecting switch and circuit breaker conscientiously while installing. The products are before being commissioninged, check whether nominal voltage, rated current of every executive component conformed with the actual conditions carefully. And operate with the organization, in order to check whether various movements are correct. Every parameter of circuit breaker adjust already during routine test, user don't the starting up check; After carrying on the withstand voltage test on request, can install. The all right single pole of circuit breaker is erected, can also erect with one pair of poles. The circuit breaker should be installed on specialized steelframe steadily, firmly. The products are examined small regularly, mainly check whether the movements of the circuit breaker are normal. The circuit breaker with disconnecting switch, the disconnecting switch is checked twice every year, the content checks whether the mechanical interlock movements between disconnecting switch and circuit breaker are normal, and inject in the movable part into some grease. Transport, confirm and store? ? Must fail while transporting the whole platform is packed into the close packing box and fixed. Transporting can't be turned over, sloped, need to take the earthquake counter measure in the course. While exceeding and hanging the body of the circuit breaker, four rings colluding on the container body, can't carry the epoxy insulating cylinder directly. Exceed, hang the circuit breaker lead the disconnecting switch, the weight is partial to the side of disconnecting switch, should go on slowly while lifting. Should confirm the work as follows after receiving the circuit breaker while confirming users: Check that packs damaging. Is it complete to contrast the packing list audit file of the products, attachment. Check whether the technical parameter on the data plate of circuit breaker, certificate of product inspection accord with the order requirement. Storing a circuit breaker should be left in drying, ventilates, dampproof indoor resisting shock and preventing the harmful gas from attacking, preserve and should check the environment regularly and fulfil requirements for a long time. Case, unpack and keep and should go on in the dry indoor, need to products and every part to check whether it is intact and conforming or not.
