Abstract
The utility model discloses a novel anti-lightning impulse hydraulic and electromagnetic breaker comprising a coil part, an arc extinguishing part, an operation mechanism and wiring pins, wherein one end of an oil damper is connected with an outlet wire terminal of a coil, and the other end is connected with an inlet wire terminal of the coil. The breaker also comprises an air discharge tube which is arranged in the main body between wiring pins; a lead wire at two ends of the air discharge tube is connected to the inlet wire terminal and the outlet wire terminal of the coil through welded connection; the gas discharge tube has the advantages of having high capacity of discharge current, small parasitic capacitance, lower residual voltage and having obvious advantage of protecting a high frequency electronic circuit; and when a lightning impulse current flows through the breaker, the bypass of the air discharge tube shunts the lightning impulse current to reduce the impulse current flowed by the coil, thus making the insufficient flux generated by the coil be not enough to move the iron core in place and making the armature be not enough to be absorbed by the pole shoe immediately so that the breaker is tripped so as to guarantee that a communication base station continuously power is powered up.
Description
Technical field
The utility model is widely used in the supplied by AC/DC electricity system fields such as the telecommunication equipments such as communication power supply, communication base station, computer and ancillary equipment thereof, industrial automation control system, LED track lamp system, generator, multiple power source system, UPS no-break power unit, portable power source equipment, railway signal system, railway locomotive, electrical system peculiar to vessel, Aero-Space.
Background technology
Hydraulic electromagnetic breaker is circuit breaker of new generation.Compare with air switch or ordinary hot magnetic-type circuit breaker; owing to adopted the hydraulic-electromagnetic trip gear; make it have the advantages such as not influenced by ambient temperature, that working stability is reliable, precision is high, the protection Curve selection is various, the life-span is long; shell frame current class can be divided into 30A, 50A, 100A third gear, mainly plays overload and short-circuit protection effect.
Normal operation: under normal load, the electric current of flowing through coil is less than or equal to the circuit breaker rated operational current, the magnetic flux that coil produces is less, be subject to the damping action of oil damper medi-spring elastic force and hydraulic oil, iron core can not be drawn onto pole shoe, armature is failure to actuate, and circuit breaker keeps normal operating conditions.
Overload protection: under the overload, the electric current of flowing through coil is greater than the circuit breaker rated operational current, and the magnetic flux that coil produces is enough to overcome the damping action of oil damper medi-spring elastic force and hydraulic oil, so attract iron core to move to the pole shoe direction.In the situation of overload current sustainable existence, iron core arrives pole shoe after certain time-delay, and this moment, magnetic resistance obviously reduced, and magnetic flux sharply increases, so iron core is held by pole shoe, armature is held by pole shoe, and armature drives tripping mechanism, and open circuit plays a protective role.After circuit disconnects, the circuit breaker outage, magnetic flux disappears, iron core reposition under spring action.
Short-circuit protection: during load short circuits, the electric current of flowing through coil is very large, and the magnetic flux that coil produces is enough to make armature not to wait iron core just to move to be held by pole shoe at once, and circuit breaker is threaded off at once, plays the short-circuit protection effect.
As shown in Figure 1, existing circuit device comprises handle 10, pole shoe 20, armature 30, coil rack 40, coil 50, wiring pin 60, oil damper 70, operating mechanism 80, fixed contact 90, permanent magnetism arc quenching system 100, moving contact 110, coil end of incoming cables 120, finish lead 130, auxiliary contact 150, but existent defect and deficiency: because the necessary flowing through coil of electric current, do not possess the by-pass shunt function, the shock resistance current capacity is poor.When the lightning impulse current flowing through coil, this moment, the magnetic flux of coil 50 generations was held armature 30 at once by pole shoe 20, caused circuit breaker trip.Such as in unattended confession communication base station and electric power far away, lightning impulse current can cause circuit breaker trip, causes communication disruption, needs manually again to close a floodgate.
The utility model content
The utility model addresses the above problem provides a kind of circuit breaker that gas discharge tube is installed, the situation of lightning impulse current is appearring, gas discharge tube plays the effect of shunting lightning impulse current as the bypass of coil, thereby guarantees the communication base station system continued power.
For addressing the above problem, the utility model is realized by following scheme: a kind of novel lightning impulse resistant hydraulic electromagnetic breaker, it comprises coiler part, the arc extinguishing part, operating mechanism, and wiring pin, described coiler part comprises armature, coil rack, coil, oil damper, this armature is fixedly connected on the coil rack, the coil setting is connected to the coil rack below, one end of oil damper is connected with finish lead, the other end is connected with the coil end of incoming cables, this circuit breaker also comprises gas discharge tube, this gas discharge tube setting is installed in the main body between the wiring pin, the lead-in wire at these gas discharge tube two ends is connected by welding to coil end of incoming cables and finish lead, becomes the bypass of coil.
Described arc extinguishing partly comprises fixed contact, permanent magnetism arc quenching system, moving contact, described moving contact attended operation mechanism, and described permanent magnetism arc quenching system is fixedly mounted on the fixed contact both sides.
Described operating mechanism is connected with pole shoe, handle, and this pole shoe is arranged on the armature top.
Advantage of the present utility model: the advantage that gas is put pipe is that the logical capacity of electric current is large, parasitic capacitance is little, residual voltage is lower; protection to High-Frenquency Electronic Circuit has obvious advantage; when lightning impulse current is flowed through circuit breaker; gas is put pipe by-pass shunt lightning impulse current; the impulse current of coil circulation is reduced, the magnetic flux deficiency that this moment, coil produced so that iron core move into place, also deficiency so that armature held by pole shoe at once; circuit breaker is not threaded off, and can guarantee the communication base station system continued power.
