                The sort of high-pressured switch ark reachs common breakdown

                来源: 作者:Stand originally 时间:2008-12-25 Tag: 点击:
                High-pressured switch ark is the very important electric equipment in power system. Aggravation of switch cabinet moving position is one of causes that cause power system occurrence trouble. On January 1, 2002, 60508 switch produce ark of switch of high pressure of room of distribution of 5BS of plastic plant of company of Qi Lu petrifaction shine explode, bring about whole apparatus to jockey, caused huge pecuniary loss.
                One, the sort of high-pressured switch ark
                (one) outdoor type and indoor type
                From high-pressured switch ark find a place for will divide, can divide for outdoor type and indoor type two kinds, 10KV and use indoor type more below. According to circuitry plan different, can divide wait for ark of section of ark of switch of oil of ark of switch of line of pass in and out, contact, generatrix. Switch of line of 10KV pass in and out installs little oily breaker or vacuum breaker more inside ark, the drill that breaker place matchs moves an orgnaization to hold motive compose or electromagnetism to hold motive form for bedspring more, also have match a hand to move those who hold motive compose or permanent magnetism to hold motive form. Different switch ark has bigger difference on the structure, this will affect the choice of sensor and installation.
                (2) stationary and removed type
                Will divide from the use of high-pressured switch ark, can divide mix for stationary removed type. Previously, the factory of power plant is used with electric system habit removed formula switch ark, and power supply system uses fixed ark more. Succeed as the ceaseless development of the progress of science and technology and new product, use of a lot of conventions also is in produce change. For example the metal is armored removed formula switch ark is on the foundation of stationary switch ark development rises. The metal is armored removed formula switch ark is whole sealing structure, each function closet is separated each other, normal operation function and prevent handle a function by accident 100 add perfect and reasonable, the overhaul is convenient, the sex of on the safe side that its run rises greatly.
                (3) the development of high-pressured switch ark
                In recent years, as the development of technology of small-sized vacuum breaker and promotion, ark of buy formula switch serves as a metal in close armored removed the new development of switchgear got type develop very quickly. The advantage of buy ark is compared in much, the most important is handcart miniaturization and the mechanization of the craft that make, make of handcart and slideway make more accurate. Have the product of many manufacturer even, its handcart includes advocate breaker and cabinet put oneself in another's position need not be inside the factory man-to-man debug, when leaving factory, deliver goods respectively after the spot, debug a success very easily also, can make sure handcart pass in and out goes to the lavatory neatly likewise. Because this product interchangeability is good, the effect that suffers condition of spot ground level is very little. This kind of metal is armored removed formula switch ark runs on the safe side, the overhaul is safeguarded convenient. What use because of this power supply system is increasing also.
