Abstract
The utility model discloses the emergency circuit of a kind of Control, including relay coil loop and emergency light loop；Connected between access power supply positive pole and power supply negative pole with relay coil by normally closed button in described relay coil loop；Described relay circuit is the series loop that emergency power supply, relay normally-closed contact and emergency light are formed；Described relay coil loop is connected in parallel with emergency light loop, and wherein power supply positive pole is connected to the positive terminal of emergency power supply by relay normally open contact, and power supply negative pole is connected to the negative pole end of emergency power supply；Described emergency power supply carries charging device.This utility model is by using common relay as the major control element of emergency circuit, and circuit theory is all easily understood with structure, it is simple to later maintenance, and meanwhile, the design and installation of circuit is low with use cost, is suitable for extensively application.
Description
Technical field
This utility model relates to emergency lighting field, specifically refers to the emergency circuit of a kind of Control.
Background technology
Accident emergency illumination, escape hatch mark and display lamp is mainly included in fire emergency system, it is when breaking out of fire after normal illumination dump, guide trapped personnel to evacuate or launch fire fighting and rescue action and arrange, rationally select emergency lighting system r, the mode of connection, carry out line service, directly influence the performance of fire emergency systemic effect, but find in daily inspection, a lot of emergency systems are the most complicated due to circuit, cost is high, it is unfavorable for later maintenance, causes emergency system usually to break down.
Utility model content
The purpose of this utility model is to provide a kind of circuit simple, it is simple to the emergency circuit of the Control of maintenance.
This utility model is achieved through the following technical solutions: include relay coil loop and emergency light loop；Connected between access power supply positive pole and power supply negative pole with relay coil by normally closed button in described relay coil loop；Described relay circuit is the series loop that emergency power supply, relay normally-closed contact and emergency light are formed；Described relay coil loop is connected in parallel with emergency light loop, and wherein power supply positive pole is connected to the positive terminal of emergency power supply by relay normally open contact, and power supply negative pole is connected to the negative pole end of emergency power supply；Described emergency power supply carries charging device.
Under normal circumstances, normally closed button closes, and relay coil obtains electric, and relay normally open contact closes, and relay normally-closed contact disconnects, and emergency power supply is in charged state, and emergency light is in OFF state；Time emergent, power supply positive pole is no longer powered with power supply negative pole, relay coil dead electricity, and relay normally open contact disconnects, and relay normally-closed contact closes, and emergency power supply is powered to emergency light, and emergency light is bright.
In order to this utility model is better achieved, further, described emergency light is LED, and described emergency power supply comprises electrical measurement and charge protection device.
Use the emergency light of LED form, saves energy can be made, extend the power-on time of emergency power supply；Electrical measurement machine charge protection device can control to charge and do not charge automatically according to the electricity of emergency power supply, makes emergency power supply be unlikely to because of overcharge and damages.
This utility model has the following advantages and beneficial effect:
This utility model is by using common relay as the major control element of emergency circuit, and circuit theory is all easily understood with structure, it is simple to later maintenance, and meanwhile, the design and installation of circuit is low with use cost, is suitable for extensively application.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Wherein: 1 normally closed button, 2 relays, 3 power supply positive poles, 4 power supply negative poles, 5 emergency power supplies, 6 emergency lights, 21 relay normally open contacts, 22 relay normally-closed contacts.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1:
The circuit theory diagrams of the present embodiment are as it is shown in figure 1, include relay coil loop and emergency light loop；Connected between access power supply positive pole 3 and power supply negative pole 4 with relay coil 2 by normally closed button 1 in described relay coil loop；Described relay circuit is the series loop that emergency power supply 6, relay normally-closed contact 22 and emergency light 5 are formed；Described relay coil loop is connected in parallel with emergency light loop, and wherein power supply positive pole 3 is connected to the positive terminal of emergency power supply 6 by relay normally open contact 21, and power supply negative pole 4 is connected to the negative pole end of emergency power supply 6；Described emergency power supply 6 carries charging device.
Under normal circumstances, normally closed button 1 closes, and relay coil 2 obtains electric, and relay normally open contact 21 closes, and relay normally-closed contact 22 disconnects, and emergency power supply 6 is in charged state, and emergency light is in OFF state；Time emergent, power supply positive pole 3 is no longer powered with power supply negative pole 4, and relay coil 2 dead electricity, relay normally open contact 21 disconnects, and relay normally-closed contact 22 closes, and emergency power supply 6 is powered to emergency light, and emergency light is bright.
Embodiment 2:
The present embodiment does optimization further on the basis of above-described embodiment, and further, described emergency light 5 is LED, and described emergency power supply 6 comprises electrical measurement and charge protection device.Other parts of the present embodiment are same as the previously described embodiments, therefore repeat no more.
Use the emergency light of LED form, saves energy can be made, extend the power-on time of emergency power supply 6；Electrical measurement machine charge protection device can control to charge and do not charge automatically according to the electricity of emergency power supply, makes emergency power supply be unlikely to because of overcharge and damages.
The above; it it is only preferred embodiment of the present utility model; not this utility model is done any pro forma restriction, every according to technical spirit of the present utility model, above example is made any simple modification, equivalent variations, within each falling within protection domain of the present utility model.
