Abstract
The utility model discloses an automatic disconnector for standby state, which is characterized in that a live wire terminal is connected with an end of a normally closed switch of an electromagnetic relay through a lead; an ammeter deflecting coil is connected with a step up transformer; the ammeter deflecting coil is connected with an ammeter; the step up transformer is connected with a live wire terminal of an output terminal and a moving contact on an ammeter pointer through the leads; and a second electromagnetic relay coil is connected with a normally opened switch of the electromagnetic relay through the leads. Through the above arrangement, the automatic disconnector for standby state is connected between a circuit and an electrical appliance; and the automatic disconnector for standby state can automatically cut off the power source, so that the electrical appliance is power off and energy consumption is not caused, when the electrical appliance is at a standby state.
Description
Technical field
The utility model relates to a kind of automatic detection electric current makes circuit breaker, is a kind of standby automatic cutout that is used for when little electric current automatic shutoff circuit specifically.
Background technology
Various electrical appliances also can consumed power at holding state, causes energy waste.At present, various insert rows on the market do not have in the function of electrical appliance at holding state automatic shutdown circuit of following time, thereby cause the waste of the energy.
Summary of the invention
The purpose of this utility model is to provide a kind of can detect the standby automatic cutout of automatic shutoff circuit to the little current status of circuit.
To achieve these goals, firewire binding post of the present utility model is connected with an end of electromagnetic relay normally closed switch by lead, the other end of electromagnetic relay normally closed switch is connected with an end of electromagnetic relay normal open switch and trigger switch respectively by lead, the other end of electromagnetic relay normal open switch is connected with step-up transformer by lead, be connected with the ammeter deflecting coil at step-up transformer, the ammeter deflecting coil is connected with ammeter, step-up transformer is connected by the moving contact on the pointer on lead and output firewire binding post and the ammeter pointer, the ammeter fixed contact is connected with an end of delay integrated circuit by lead, the other end of delay integrated circuit is connected with first electromagnetic relay coil by lead, first electromagnetic relay coil is by lead and zero line binding post, output zero line binding post is connected with second electromagnetic relay coil, and second electromagnetic relay coil links together by lead and electromagnetic relay normal open switch.
By above setting, the utility model is being connected between circuit and the electrical appliance, under the electric appliance standby state, the utility model can be cut off the electricity supply automatically, uses appliance cut-off, can not cause energy resource consumption.
Description of drawings
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is a circuit connection diagram of the present utility model.
Among the figure: 1, firewire binding post 2, zero line binding post 3, electromagnetic relay normally closed switch 4, first electromagnetic relay coil 5, electromagnetic relay normal open switch 6, second electromagnetic relay coil, 7, moving contact 13, ammeter fixed contact 14, output firewire binding post 15, output zero line binding post on the trigger switch 8, step-up transformer 9, ammeter deflecting coil 10, ammeter pointer 11, delay integrated circuit 12, pointer.
Embodiment
As shown in Figure 1, firewire binding post 1 of the present utility model is connected with an end of electromagnetic relay normally closed switch 3 by lead, the other end of electromagnetic relay normally closed switch 3 is connected with an end of electromagnetic relay normal open switch 5 and trigger switch 7 respectively by lead, the other end of electromagnetic relay normal open switch 5 is connected with step-up transformer 8 by lead, be connected with ammeter deflecting coil 9 at step-up transformer 8, ammeter deflecting coil 9 is connected with ammeter, step-up transformer 8 is connected by the moving contact 12 on the pointer on lead and output firewire binding post 14 and the ammeter pointer 10, ammeter fixed contact 13 is connected with an end of delay integrated circuit 11 by lead, the other end of delay integrated circuit 11 is connected with first electromagnetic relay coil 4 by lead, first electromagnetic relay coil 4 is by lead and zero line binding post 2, output zero line binding post 15 is connected with second electromagnetic relay coil 6, and second electromagnetic relay coil 6 links together by lead and electromagnetic relay normal open switch 5.
By above setting, the utility model is being connected between circuit and the electrical appliance, during work, click 7 trigger switches, second electromagnetic relay coil 6 gets electric, 5 adhesives of electromagnetic relay normal open switch, output firewire binding post 14 gets electric operate as normal.If electrical appliance operate as normal, ammeter pointer 10 will deflection, moving contact 12 on the pointer and ammeter fixed contact 13 disconnect, delay integrated circuit 11 just can not get, circuit is normally exported, if we are with the electrical appliance standby or close, ammeter pointer 10 is will deflection very little or return zero, and the moving contact 12 on the pointer will contact with ammeter fixed contact 13, delay integrated circuit 11 gets electric work, pick up counting, when reaching the fixed time, first electromagnetic relay coil 4 will be got, electromagnetic relay normally closed switch 3 will disconnect, the entire circuit outage, electromagnetic relay normal open switch 5 also can disconnect, and circuit is in the zero-power state.If re-use,, can reply the normal power supply state as long as click trigger switch 7 again.
