Abstract
An automatic time-delay breaker comprises an air breaker, the air breaker is provided with a time-delay switch. An under-voltage release is also included, and the time-delay switch is arranged in the line connected with the under-voltage release. According to the air breaker, the time-delay switch is additionally provided, the air breaker is controlled by a PC terminal or a wireless local area network, operation is convenient, and remote control is available.
Description
Technical field
The utility model belongs to delay circuit breaker technical field, relates to a kind of automatic time delay circuit breaker.
Background technology
In routine work life, the electrical equipment such as the fax of company, server, printer often needs to move a period of time after the quitting time.Such as client After Hours transmitting file come, must arrange employee to work overtime, otherwise machine one must headed straight for, or corporate server is regularly closed, but power supply in wireless routing and computer is all in working order, causes energy loss, produces extra charge simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of automatic time delay circuit breaker, and what solve that prior art exists cannot the total lock of time-delay closing, causes the problem of energy waste.
The technical solution of the utility model is that automatic time delay circuit breaker, comprises air circuit, is provided with delay switch in air circuit.
Feature of the present utility model is also:
Air circuit comprises device for under-voltage releasing equipment, and delay switch is arranged on the circuit being connected with device for under-voltage releasing equipment.
The utlity model has following beneficial effect:
1, the utility model adds delay switch in air circuit the inside, can make electrical equipment after automatic shutdown, thoroughly close Zong Zha, has avoided the waste of the energy.
2, electrical equipment only has and thoroughly cuts out total lock and could eliminate consumption.The utility model adopts delay switch, has realized mechanical delay and has opened circuit, and does not need to arrange specific people to remove to close the total lock of power supply, not only saved manpower, and cost is low, and functional reliability is strong.
Accompanying drawing explanation
Fig. 1 is the utility model automatic time delay breaker structure schematic diagram;
Fig. 2 is the utility model workflow diagram.
In figure, 1. retracting spring, 2. main contacts, 3. connecting rod, 4. latch hook, 5. push rod, 6. overcurrent release, 7. under-voltage de-mouthpart, 8. delay switch.
Embodiment
Automatic time delay circuit breaker, comprise air circuit, air circuit comprises main contacts 2, overcurrent release 6 and the device for under-voltage releasing equipment 7 being arranged in circuit, and overcurrent release 6, device for under-voltage releasing equipment 7 all connect in the line by coil, are provided with delay switch 8 in the coil line of device for under-voltage releasing equipment 7.
Also comprise retracting spring, connecting rod and latch hook, retracting spring is arranged on connecting rod one end, and connecting rod is connected with latch hook touch-type.
Thereby overcurrent release 6, device for under-voltage releasing equipment 7 are all controlled disconnection or the connection of being connected of latch hooks 4 and connecting rod 3 or disconnection control circuit by push rod 5.
Operation principle:
1, under normal condition, delay switch 8 closures, release-push 1 is pressed, and main contacts 2 switches on power, and electric current is through overcurrent release 6, device for under-voltage releasing equipment 7, and connecting rod 3 is connected with latch hook 4, and circuit keeps channel status.
2, overcurrent protection, delay switch 8 closures, electric current is excessive, the spring adhesive push rod 5 of overcurrent release 6, latch hook 4 perks, connecting rod 3 is released spring 1 and retracts, and main contacts 2 disconnects, circuitry cuts.
3, under-voltage protection, delay switch 8 closures, voltage is too small, and device for under-voltage releasing equipment 7 suction reduce, and push rod 5 is by spring pull-up, and latch hook 4 breaks off relations with connecting rod 3, and connecting rod 3 is released spring 1 and retracts, and main contacts 2 disconnects, circuitry cuts.
4, timing turning off circuit, when delay switch 8 arrives the scheduled time, delay switch 8 disconnects, and device for under-voltage releasing equipment 7 is without suction, and push rod 5 is by spring pull-up, and latch hook 4 breaks off relations with connecting rod 3, and connecting rod 3 is released spring 1 and retracts, and main contacts 2 disconnects, circuitry cuts.
Claims (2)
