Embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As shown in Figure 1, electricity charge arrearage sound and light alarm resetting system, comprise the first branch circuit, the second branch circuit, the 3rd branch circuit, the 4th branch circuit and quintafurcation circuit, the input end in parallel of described first branch circuit, the second branch circuit, the 3rd branch circuit, the 4th branch circuit and quintafurcation circuit is by fuse 4 cut-in operation positive source, the parallel outputs cut-in operation power cathode of described first branch circuit, the second branch circuit, the 3rd branch circuit, the 4th branch circuit and quintafurcation circuit
Described first branch circuit comprises the electric energy meter output alarm contact 10 and K1 alarm relay 5 that are connected in series, described second branch circuit comprises pilot lamp 1, hummer 2, K1 alarm relay normally opened contact and K3 reset relay normally closed contact, described pilot lamp 1, K1 alarm relay normally opened contact and the series connection of K3 reset relay normally closed contact, described hummer 2 is parallel to the two ends of described pilot lamp 1, described 3rd branch circuit comprises K3 reset relay 7, pushbutton switch 3 and K3 reset relay normally opened contact, described K3 reset relay 7 and pushbutton switch 3 are connected, described K3 reset relay normally opened contact is parallel to the two ends of described pushbutton switch 3, described 4th branch circuit comprises the electric energy meter be connected in series and exports trip contact 8 and K2 tripping relay 6, described quintafurcation circuit comprises the K2 tripping relay normally opened contact that is connected in series and is separated electrical apparatus release 9.
The preferred forms of electricity charge arrearage sound and light alarm resetting system is accessed the AC power of acoustic-optic alarm by fuse 4, as pilot lamp 1, hummer 2, K1 alarm relay 5, K2 tripping relay 6, K3 reset relay 7, is separated the use of electrical apparatus release 9 working power.The working power of acoustic-optic alarm accesses five parallel branch circuits:
1. connect with K1 alarm relay 5 and access working power in electric energy meter output alarm contact 10, as the first branch circuit;
2. the parallel circuit of pilot lamp 1 and hummer 2 is connected, as the second branch circuit with K1 alarm relay 5 normally opened contact, K3 reset relay 7 normally closed contact;
The parallel circuit in series of 3.K3 reset relay 7 and pushbutton switch 3 and K3 reset relay 7 normally opened contact, as the 3rd branch circuit;
4. electric energy meter output trip contact 8 is connected with K2 tripping relay 6 and is accessed working power, as the 4th branch circuit;
5.K2 tripping relay 6 normally opened contact be separated electrical apparatus release 9 and connect and access working power, as quintafurcation circuit.
The invention is by access the 3rd branch circuit, and by the second branch circuit transformation of former acoustic-optic alarm, connect into K3 reset relay 7 normally closed contact, form electrical installation schematic diagram as shown in Figure 1, realize when electric energy meter will export passive warning, trip signal, this device still carries out action according to original circuit theory.When occur can not power purchase eliminates the situation of sound and light alarm in time time, operator on duty can select to press the button switch 3, and latching circuit action makes sound light alarming circuit dead electricity, and temporarily elimination sound and light alarm signal, avoids the accelerated deterioration of circuit original paper even to burn.
Normal at outside plant-grid connection, and under the state of fuse 4 work, the working power of acoustic-optic alarm is effective.When electric energy meter output alarm contact 10 closes, K1 alarm relay 5 switches on power, the first branch circuit work; First branch circuit work drives K1 alarm relay 5 normally opened contact to close, and the second branch circuit work, pilot lamp 1 and hummer 2 switch on power and send sound and light alarm signal.Close when electric energy meter exports trip contact 8, K2 tripping relay 6 switches on power, the 4th branch circuit work; 4th branch circuit work drives K2 tripping relay 6 normally opened contact to close, and quintafurcation circuit working, is separated electrical apparatus release 9 action, and electricity consumption master switch disconnects, and make external power source dead electricity, acoustic-optic alarm quits work.When needs eliminate sound and light signal report to the police time, press the button switch 3, the 3rd branch circuit work, K3 reset relay 7 action and K3 reset relay 7 normally opened contact close; K3 reset relay 7 normally closed contact disconnects, and the second branch circuit quits work, pilot lamp 1 and hummer 2 deenergization, sound and light alarm blackout.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
