Description
Technical field
The invention belongs to power supplying and distributing equipment technical field, be specifically related to a kind of intelligent breaker.
Background technology
Circuit breaker is the electrical equipment of control and protection in electric power system.Disjunction actuator plays and drives moving contact motion in circuit breaker, makes the effect that moving contact and fixed contact close or separate, thus the break-make of realizing circuit.The quality of disjunction actuator is the speed of separately moving contact and fixed contact, and The faster the better! Break-time can be controlled in industry, within 5 milliseconds, to be excellent.
In current industry, like product disjunction actuator mainly contains Purely mechanical and Single electromagnet formula.Purely mechanical disjunction actuator is the combination of one group of sheet metal component and spring.By the pulling force of spring when attonity time, can keep sound contact separately, when needs breaker closing, need manual operation, make sound contact, and pin with bayonet lock; When dump energy exceedes threshold value time, by bimetal leaf heating principle, open bayonet lock, the spring of disjunction actuator is had an effect, sound contact is occurred, and separately manual operation again again when needs reclose circuit time, makes sound contact be in the position of contact.The breaking capacity of this mechanism of disjunction actuator, depend primarily on the pulling force of spring in mechanism, but because locus is limited, material itself limits and needs to take into account each side factors such as making capacity, the pulling force of this spring cannot infinitely strengthen, and is therefore difficult to effectively promote breaking capacity.
Single electromagnet formula disjunction actuator is the combination of a piece of electromagnet, iron core and spring.By the thrust of spring when attonity time, can keep sound contact separately; When needs breaker closing, control to make electromagnet coil power produce magnetic force by PCB, this magnetic force overcomes the thrust of spring, makes sound contact; When dump energy exceedes threshold value time, control to make electromagnet coil dead electricity by PCB, magnetic force disappears, and the thrust of spring promotes whole disjunction mechanism, makes sound contact separately; When needs reclose circuit time, control electromagnet coil is energized generation magnetic force again by PCB, this magnetic force overcomes the thrust of spring, makes the position of sound contact.The breaking capacity of this mechanism of disjunction actuator, depends primarily on the magnetic force of electromagnet and the pulling force of spring in mechanism, but due to rotating mechanism quality bigger than normal, simultaneously also facing spring tension cannot infinitely strengthen, and is therefore difficult to effectively promote breaking capacity.
