Description
Technical field
The present invention relates to a kind of air switch, be specifically related to a kind of air switch that can connecting sensor, belong to technical field of electrical equipment.
Background technology
Existing air switch is low-voltage circuit breaker namely, is used as connection, disjunction and carrying rated operational current in circuit, and can be in the situation that circuit and motor transship, short circuit, the under-voltage protection.Its function is equivalent to electrical appliance part or whole function summations such as knife switch, overcurrent relay, no-voltage relay, thermal relay and earth leakage protective device, is a kind of important protective device in low-voltage network.
As shown in Figure 1, existing automatic air-break switch comprises main contacts 1, free tripping mechanism 2, overcurrent trip 3, shunt release 4, thermal overload release 5, under-voltage release 6, stop button 7 and bimetal leaf 8.
The main contacts 1 of automatic air-break switch is the moving operation of armrest or electric switch-on.After main contacts 1 closure, free tripping mechanism 2 is locked in main contacts 1 on closing position.The thermal element of the coil of overcurrent trip 3 and thermal overload release 5 is connected with main circuit, the coil of under-voltage release 6 and power supply parallel connection.When circuit is short-circuited or seriously transship, the armature adhesive of overcurrent trip 3, make free tripping mechanism 2 actions, and main contacts 1 disconnects main circuit.When circuit overloads, the heating of the thermal element of thermal overload release 5 makes on bimetal leaf 8 crooked, promotes free tripping mechanism 2 actions.When the circuit under voltage, the armature of under-voltage release 6 discharges, and also makes free tripping mechanism 2 actions.4 of shunt releases are as far distance controlled use, and when normal operation, its coil cut off the power supply, at needs, when controlling, press starting button, make coil electricity, and armature drives 2 actions of trip free machine, makes main contacts 1 disconnection.
Automatic air-break switch because there is multi-protective function (overload, short circuit, under voltage protection etc.), operating value is adjustable, breaking capacity is high, easy to operate and safety etc. advantage, so be widely used at present.
, when residential building or public place breaking out of fire, the danger of existing air switch None-identified outside, also can't do power down process.Can only first there be special electrical management personnel to do power down process, then the water fire fighting.The time of this wait can stop over fire fighting, gives by fire tiredly that personnel's life has brought threat, also can result in greater loss to property.
While in residential building or factory floor, coal gas or other hazardous gas spillage occurring, existing air switch is None-identified also.When gas concentration reaches one regularly, the unlatching of electrical appliance may cause blast.In factory floor, when dangerous leak of liquid, may jeopardize the safety of electrical appliance, air switch also None-identified comes from outside electricity consumption danger.Above situation threatens or loses all can to personnel's life and property.
In a word, existing air switch can only be identified the abnormal conditions of electric line and electrical appliance inside, and the abnormal conditions of None-identified electric line and electrical appliance outside.When electric line and the outside generation of electrical appliance emergency, also can't cut off the electricity supply.
Therefore invent that a kind of to respond to the novel air switch that fire or hazardous gas, leak of liquid etc. come from the emergency of electric line and electrical appliance outside be problem demanding prompt solution.
Summary of the invention
The present invention for solve existing air switch can't induction line and electrical appliance beyond the problem of burst emergency, a kind of air switch that can connecting sensor is provided.
Technical scheme of the present invention is:
Air switch that can connecting sensor, comprise main contacts, free tripping mechanism, overcurrent trip, shunt release, thermal overload release, under-voltage release, stop button and bimetal leaf, also comprise electro-heat equipment, described electro-heat equipment is arranged on below bimetal leaf, and this electro-heat equipment is connected with transducer.
Described electro-heat equipment is heating resistor or heating wire.
Air switch that can connecting sensor, comprise main contacts, free tripping mechanism, overcurrent trip, shunt release, thermal overload release, under-voltage release, stop button and bimetal leaf, also comprise the transducer release, this transducer release is coil, share an armature with overcurrent trip, and be connected with transducer.
Described transducer release and shunt release share an armature.
Described transducer release and under-voltage release share an armature.
Beneficial effect of the present invention: the present invention is that a kind of scheme is to increase electro-heat equipment on existing automatic air-break switch structure, electro-heat equipment is arranged on below bimetal leaf, electro-heat equipment is connected with transducer, when sensor sensing during to the emergency beyond electric line and electrical appliance, output signal to electro-heat equipment, electro-heat equipment produces heat, bi-metal plate deformed fast, and then promote the free tripping mechanism action, cut off the electricity supply.Another kind of scheme of the present invention is to increase the transducer release on existing automatic air-break switch structure, the transducer release is connected with transducer, when sensor sensing during to the emergency beyond electric line and electrical appliance, output signal to this transducer release, armature movement, the action of promotion free tripping mechanism, emergency power off.When electric line and electrical appliance external environment condition generation emergency, application apparatus of the present invention, can cut off the electricity supply in time, and the present invention is the people's livelihood, industrial being with a wide range of applications.
