Abstract
The invention relates to an arc extinguishing agent for an arc extinction cabinet. The arc extinguishing agent comprises the following components in parts by weight: 15-25 parts of silicon dioxide, 1-1.5 parts of sodium chloride, 0.5-1 part of potassium chloride, 0.5-1.2 parts of calcium chloride, 0.2-0.6 part of barium chloride, 1-2 parts of acetone, 2-3 parts of waterborne tackifying resin, 1-2 parts of dibutyl phthalate, 1-2 parts of waterborne polyurethane, 1-2 pars of anticorrosion mildew preventive A2, 0.3-0.5 part of asbestos powder, 1-2 parts of titanium dioxide, 1-2 parts of natural rubber, 1-2 parts of elastomer and 0.1-0.2 part of sepiolite. The components of the arc extinguishing agent are easily available and low in cost; due to the components of the materials, the service life of the arc extinction cabinet can be prolonged, the anti-aging degree is high, and the voltage resistance value is high; and meanwhile, fuses adopting the arc extinguishing agent can satisfy the demand of a 250A breaking capacity test, and even the fuse can perform short-circuit protection.
Description
Technical field
The present invention relates to electric power fusing technical field, particularly relate to for arc extinction cabinet arc quenching agent.
Background technology
Along with the development of present electrical network, overhead transmission line progressively to replace by the cable line of solid insulation be a kind of inexorable trend.Due to the build-up effect that solid insulation punctures, its internal overvoltage, the arc grounding over-voltage particularly produced during electrical network generation single-phase intermittent arc earthing and the ferro-resonance over-voltage excited thus, oneself becomes one of this kind of electric power netting safe running and threatens greatly, wherein serious with single-phase arc grounding over-voltage.It is saturated that arc grounding over-voltage can make voltage transformer occur, and excites ferro resonance, cause voltage transformer heavy overload, cause fuse blows or instrument transformer to burn.Simultaneously because the arc grounding over-voltage duration is long, energy very easily exceedes the ability to bear of lightning arrester, causes Explosion of on Arrester.The accumulation that the overvoltage of amplitude that arc grounding produces besides exacerbates the solid insulations such as cable destroys even to puncture blows out.
In existing arc extinction cabinet, fusible link generally must be provided with arc quenching agent, when fault current is excessive or short circuit disconnects moment, the electric arc that on it, meeting produce power is powerful, when not being provided with arc quenching agent in it, fuse can burn and even produce the danger of blast, light then burn other valuable elements in circuit, heavy what for can because of arc ignition breaking out of fire or danger of hurting sb.'s feelings.Therefore the harm that when portioned product has started additionally to add arc quenching agent to avoid the excessive disconnection of possible electric current to protect in this type of microfuze existing, generation electric arc brings.And existing arc quenching agent only adopts single SiO2 (quartz sand) mostly, its arc quenching effect can only meet makes microfuze by requiring maximum 63A breaking capacity test in IEC60127 standard, cannot meet the industry requirement be showing improvement or progress day by day.
