The electricity that shakes refers to because thunderbolt, short circuit or other reason cause the phenomenon of electrical network short-time fluctuations or short supply interruption.It is very harmful to the normal production of enterprise, especially the chemical enterprise of continuous pipeline, the stability requirement of electric equipment operation is high, the stability of rolling electricity meeting severe jamming electric power system, the seriality that impact produces, gently then causes raw materials for production waste, the damage of production equipment, heavy then lead to security incident, cause the economic loss that cannot retrieve, have a strong impact on the economic benefit of enterprise.The chemical enterprise that continuous produces has a power failure whenever, it is possible to create maximum fault be line clogging, and its loss is also main at this, and especially to large-scale plant, after unplanned property is stopped work, block clearing cost is very big.As annual sales amount reaches certain large chemical complex of more than 30 hundred million yuan, because Thunderstorm Weather is more, especially in 7~JIUYUE, often having rolling electric tripping in various degree every year, according to measuring and calculating, large area tripping operation power failure in 2010 reaches three times, and loss is up to more than 5,000,000 yuan.Thus, it is prevented that because shaking the electric tripping grinder produced, to the economic benefit improving chemical enterprise, there is profound significance.
The main cause that the electricity that shakes produces has: owing to electrical network is grid-connected, the expanding day of looped network and supply transformer capacity increase increasing of the equipped circuit that brings so that the voltage pulsation probability caused because of adjacent loop fault increases, and causes power supply instantaneous loss of pressure;Due to the decompression in short-term that supply line or upper level supply line generation transient fault cause;Due to the voltage flicker that thunderbolt causes;When there being circuit to be short-circuited in electrical network, before faulty line is cut-off, the voltage of this short dot near zone is greatly lowered.
In prior art, due to reasons such as thunderbolt, circuit transient faults, distribution system is easily generated rolling electricity, shakes in electric process, and system voltage decreases.The no-voltage release of chopper is an electric magnet, and coil losing electricity moment can discharge armature under the drive of spring, then drives tripping mechanism action, and chopper completes trip operation.Shaking after electricity, system voltage recovers in time, owing to low-voltage circuit breaker is without automatic reclosing function, it is necessary to manual operation closing by hand recovers power transmission.When distribution system is shaken electric, if no-voltage release can take-off again after time delay several seconds, after system voltage momentary recovery is normal, electric power system is maintained normal power supply, thus avoiding rolling electricity to cause the generation of power-equipment moment stoppage in transit phenomenon, the system that will significantly reduce shakes electricity to the impact requiring the continuous condition of production, reduces economic loss.
Summary of the invention
