Abstract
The utility model relates to a multifunctional non-arcing switch, and is an industrial electric appliance control device. By the new circuit structure and composition, the non-arcing closing and disconnection of the switch are realized when a circuit system works, and the situation is avoided that the closing or disconnection of a general switch generates an arc to thereby cause harm. The multifunctional non-arcing switch of the utility model is composed of a main contact, an integrated control unit, an auxiliary contact and a coil. When the coil is electrified, the integrated control unit is conducted via the auxiliary contact, at this time, no current passes through the main contact, and then, the main contact is in non-arcing closing and supplies power to a load, and the integrated control unit is disconnected automatically, thereby realizing the non-arcing closing of the switch. After the work is finished, the coil loses power, so that the main contact is in non-arcing disconnection. The multifunctional non-arcing switch of the utility model is the composition element of an industrial electric appliance system, and is used for a control circuit of the circuit system.
Description
Technical field
The utility model relates to the industrial electrical equipment control device, specifically a kind of multi-functional Switch without electric arc.
Background technology
Switch is control element commonly used during industrial electrical equipment is controlled, extensive use in all kinds of control circuits.So switch is closed or tend to produce the arcing phenomenon while disconnecting in actual applications, thereby can cause great harm.Mainly contain: the existence of (1) electric arc has extended the closed time with disconnecting of switch when circuit breaks down, and has increased the weight of the harm of Circuits System short trouble; (2) high temperature that electric arc produces, can make the contact surface fusing and evaporate, and burns out insulating material, has a strong impact on load capacity; (3) because electric arc can move under electric power, thermodynamic activity, be easy to cause overflash short circuit and hurting sb.'s feelings, can bring all potential safety hazards to power circuit, as catch fire, the accident such as blast.The arc extinguishing measure that existing switch is taked is that arc-extinguishing medium and arc quenching material are made to corresponding arc-control device according to different characteristics, and the shortcoming of this class device is complex structure, high to arc extinguishing part material performance requirement, and manufacturing cost is high and arc quenching effect is also undesirable.Existing switch is without explosion prevention function, and flame-proof switch used is special switch, and complex structure, volume are large, application inconvenience.Another shortcoming of existing switch is only to have closure and break function, fault-free disjunction effect, thereby, in the circuit that switch is installed, all to install circuit breaker additional, this had both increased cost, made again the safety and reliability of whole Circuits System reduce.In sum, there are many defects in existing switch product, far can not adapt to the needs that modernization industry is produced.
Summary of the invention
For overcoming the defect of existing switch product, meet the requirement that in industrial production, circuit is controlled, the utility model provides a kind of existing switching function, the circuit breaker function is arranged again, realize the multi-functional Switch without electric arc without the arc action, to adapt to industrial demand simultaneously.
The purpose of this utility model realizes by following technical proposals, multi-functional Switch without electric arc comprises contact, control element, described contact has main contact and auxiliary contact, be parallel with integrated control unit with main contact, construction of switch is in-built coil and auxiliary contact, the switch of coil one termination subsidiary loop, an end links through auxiliary contact and integrated control unit, the switch product of contact, integrated control unit and coil complete.During work, the coil of switch obtains electric from subsidiary loop, make the first conducting of integrated control unit by auxiliary contact, now on main contact, no current passes through, and control unit makes the main contact closure subsequently, and the major loop of system powers to the load by main contact, after the main contact normal operation, integrated control unit automatic disconnection, because main contact is closed under the state that does not have electric current to pass through, historical facts or anecdotes showed switch without the arc closure.When the coil losing electricity of switch, integrated control unit conducting when main contact starts to disconnect, main contact disconnects subsequently, integrated control unit automatic disconnection when current over-zero afterwards, while disconnecting due to main contact, the conducting of integrated control unit, on main contact no current pass through, realized disconnecting without arc of switch.In addition, while overcurrent, overvoltage, under-voltage, phase shortage occurring in Circuits System, the disjunction in time of integrated control unit, disconnect rapidly main contact, plays the effect of circuit breaker, realizes the defencive function to Circuits System.
With existing like product, compare, the beneficial effects of the utility model are as follows: 1,, owing to having realized closed without arc and having disconnected, the contact of contact reduces greatly, saves silver contact simultaneously, has greatly reduced cost; 2, owing to having realized closed without arc and having disconnected, can reduce the folding spacing of contact, the volume of pull-in winding and iron core reduces equally like this, makes iron core closed steadily reliable, noiselessness after closure; 3, owing to having realized closed without arc and having disconnected, the contact of contact is difficult for scaling loss, and switch is significantly improved useful life; 4, owing to having realized closed without arc and having disconnected, can use in fire prevention, explosion-proof occasion, to replace flame-proof switch; 5, can automatic disconnection when overcurrent, overvoltage, under-voltage, phase shortage appear in Circuits System, play the effect of circuit breaker, can save circuit breaker when design of circuit system, both simplified circuit, save again cost; 6, switch is packaged into an integrated package by control unit when making, and is loaded in construction of switch, forms a complete product, directly is loaded on Circuits System during use, simple and convenient.In sum, the utility model compact conformation, volume is little, the simple structure cost is low, stable performance, life-span are long, is the preferred product that existing switch upgrade is regenerated.
