Description
Technical field
The utility model relates to a kind of air switch, is specifically related to a kind of air switch that can connecting sensor, belongs 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 transship at circuit and motor, short circuit, protect under-voltage in the situation that.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 to lean on manual operation 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, and the coil of under-voltage release 6 and power supply are in parallel.When circuit is short-circuited or seriously transship, the armature adhesive of overcurrent trip 3, makes 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 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 is power-off, at needs, when controlling, press starting button, make coil electricity, and armature drives 2 actions of trip free machine, and main contacts 1 is disconnected.
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 cannot do power down process.Can only first there be special electrical management personnel to do power down process, then 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 there is coal gas or other hazardous gas spillage in residential building or factory floor, 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 cannot 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.
Utility model content
