Into waste.In addition, the interruption of outage illumination, the also action to people bring great inconvenience.The power failure applied at present should
Anxious protection device is mainly fire-fighting emergency headlamp tool, is only capable of playing emergency lighting effect, can not cut off circuit when having a power failure and rise
Acted on to safeguard protection.The protection device of the automatic shutoff circuit used at present is bulky, complicated, and function is single, and
And emergency lighting can not be carried out.
Utility model content
The technical solution of the utility model is：
Automatic shutdown circuit and the protection switch of emergency lighting can be provided during a kind of power failure, including electromagnetic relay, it is normally opened
Type reset switch, closed type reset switch；The electromagnetic relay has two groups of open type contacts, one group of open type contact and often
Open form reset switch is in parallel, and another group of open type contact is connected to external power source by binding post and after connecing load in series；Institute
Open type reset switch, closed type reset switch and the series connection of relay electromagnet component are stated, passes through binding post and external power source phase
Even.Pressing closure open type reset switch can connect load circuit, and pressing disconnects closed type reset switch can disconnecting consumers.
Further, the electromagnetic relay also includes armature, spring, and electromagnet assembly.
Further, the protection switch also includes battery, bulb and illumination control apparatus；The battery and bulb point
Do not connected with illumination control apparatus, the illumination control apparatus is connected with external power source.
Further, the protection switch also includes insulation crust, can be used for retaining element.
The beneficial effects of the utility model are：By to open type reset switch, closed type in the case of power supply is normal
The operation of reset switch, the control to connecting and disconnecting of the circuit can be realized as regular tap.When running into power outage, device can be certainly
Dynamic circuit breaker open circuit, is protected to circuit, while illumination control apparatus makes battery connect bulb powered circuit, and bulb is carried out
Emergency lighting.After restoring electricity, illumination control apparatus makes battery disconnect bulb powered circuit, and emergency lighting terminates, and
Due to have a power failure when circuit disconnected automatically, connect load will not automatic running, avoid electrical equipment under conditions of unattended
Automatic running causes danger or the personnel to equipment periphery to impact, while electric energy caused by reducing equipment automatic running damages
Lose.

Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment is elaborated.It is emphasized that the description below is merely exemplary
, rather than in order to limit the scope of the utility model and its application.
The utility model automatic shutdown circuit and can provide the protection switch of emergency lighting when having a power failure, including electromagnetism relay
Device, open type reset switch K1, closed type reset switch K2；The electromagnetic relay has two groups of open type contacts, and one group normal
Open form contact K3 and open type reset switch K1 is in parallel, and another group of open type contact K4 is by binding post 7,8 and connects load string
External power source is connected to after connection；Open type reset switch K1, closed type reset switch K2 and the electromagnet assembly 3 are connected, and are led to
Binding post 1,2 is crossed with external power source to be connected.Battery 4 and bulb 6 connect with illumination control apparatus 5 respectively, illumination control apparatus
It is connected with external power source.As shown in Figure 1.
Fig. 2 is the structural representation of electromagnetic relay of the present utility model, and the electromagnetic relay includes electromagnet assembly
3, armature 13, spring 14, and open type contact K3, K4.The electromagnet assembly 3 is logical by electromagnet binding post 15,16
After electricity, attract armature, so that normally opened contact K3, the circuit that K4 is connected is connected.The normally opened contact K3 is connect by movable contact
Line terminals 9, stationary contact binding post 10 are connected with outside line；The normally opened contact K4 passes through movable contact binding post 11, quiet
Contact lug terminal 12 is connected with outside line.
During normal power supply, battery 4 is charged, and illumination control apparatus 5 controls the place circuit of bulb 6 to disconnect.By pressing off
After closing open type reset switch K1, electromagnet assembly 3 is powered, and attracts armature, normally opened contact K3, K4 closure, and pressing operation terminates
Afterwards, open type reset switch K1 recovers off-state, and electromagnet assembly 3 remains powered on shape by the open type contact K3 of closure
State, so as to which normally opened contact K3, K4 are remained closed, the load for being connected to binding post 7,8 is powered, and load is started working.Pressing disconnects
After open type reset switch K2, electromagnet assembly 3 powers off, and normally opened contact K3, K4 disconnection, circuit where load is cut off, loaded
It is stopped.The utility model can realize the control to connecting and disconnecting of the circuit as regular tap during normal power supply.
Happen suddenly power outage when loaded work piece, and electromagnet assembly 3 powers off, normally opened contact K3, K4 disconnection, Lighting control dress
Put 5 to connect the power supply circuit of bulb 6 battery 4, battery 4 is that bulb 6 is powered, and bulb lights, and carries out emergency lighting.
After service restoration, illumination control apparatus 5 disconnects battery 4 to the power supply circuit of bulb 6, and bulb extinguishes, and meets an urgent need
Illumination terminates, and battery 4 is charged.Because open type reset switch K1 and normally opened contact K3 are in off-state, so
Electromagnet assembly 3 can not Power resumption state, normally opened contact K3, K4 be off, and load will not be automatic because of service restoration
Operation, avoid the harmful effect caused by the load automatic running that restores electricity.
The technical solution of the utility model is described in detail above-described embodiment.Obviously, the utility model not office
It is limited to described embodiment.Based on the embodiment in the utility model, those skilled in the art can also make accordingly
A variety of changes, but it is any be equal with the utility model or similar change belong to the utility model protection scope.
