Abstract
The present invention relates to a safety fireproof energy-saving switch circuit for an electric lighting system, which comprises a power supply, electric wires, a main electric distribution disk, an electric division disk, a fuse, a normally-closed button switch, a temperature relay and a load. The switch circuit is characterized in that the circuit is divided into an unintermittent power utilization circuit and an intermittent power utilization circuit, and the hand-operated control and the automatic control can be realized. The switch circuit fundamentally eliminates unnecessary loss generated when the circuit does not work and solves the problem that power can not be cut off in time when emergency situations occur, and thereby, every section of the whole power system is safely, economically and stably operated, and the switch circuit plays a role on monitoring the whole power system.
Description
The present invention relates to a kind of lighting system switching circuit, what particularly a kind of system controlled can the energy-conservation switching circuit of fire safety.
Existing lighting system, mainly form by power supply, connecting to neutral earth connection, fuse, house lead in switch, main distribution board, distributor cap, distribution board, load circuit, electricity consumption switch, at present, it is exactly this form, after mains switch closes a floodgate, a lighting system internalname link drops into power system operation, energising round the clock, under the situation of electric loading of no use, still remain in the charging operation state, reactive loss, not only dangerous, but also exist electrical fire accident potential, when person electric shock, when electrical fire took place, each knife switch was failure to actuate and is cut off the electricity supply.And it is combustion-supporting, the outage difficulty can't resolutely be handled dangerous situation, but in fact many distribution line equipment and power consumption equipment, environment is not to switch in 24 hours round the clock throughout the year, they both can cause great loss of life or personal injury, the electrical fire accident, also can lose a large amount of energy, so general ON-OFF control circuit, be from lighting system, to root out hidden danger and public hazards completely, this often gives electrical safety, fire prevention, energy conservation causes difficulty and brings the input that increases on the primary energy, duplication of production on the secondary energy sources and power system security production, the economic stability operation gets into trouble.
Purpose of the present invention is exactly on original circuit base, increase by a cover normally closed switch circuit, main contact switch motion by A.C. contactor actuating coil in the control circuit and converter, reach the purpose of control lighting system load, outage problem when solving the circuit excess loss and emergency taking place and the safety fireproof energy-saving switch circuit for lighting system that provides.
Safety fireproof energy-saving switch circuit for lighting system, by power supply, electric wire, fuse, house lead in switch, main distribution board, distributor cap,, load forms, it is characterized in that being divided into three big circuit by main distribution board, first circuit is uninterrupted power load circuit, second circuit is to be interrupted the power load circuit, and the 3rd circuit is the switching circuit of multiple spot control.The described interruption in the power load circuit, between distributor cap and distribution board, be in series with the A.C. contactor main contacts; Described switching circuit is a multiple spot control series circuit, come out from main distribution board, link with fusing insurance and normally closed moving disconnected push-button switch in the distributor cap, connect then and often drive (moving closing) starting button switch, A.C. contactor subsidy in parallel again contact, connect the A.C. contactor actuating coil then, normally closed moving disconnected push-button switch alternately is connected with temperature control relay, forms 220 volts of ON-OFF control circuit of a phase voltage.Operation principle of the present invention is, to have lighting system now, according to technique scheme, punish into three big circuit at main distribution board, be in series with several normally closed switchs and temperature relay as required at multiple spot control normally-closed circuit, can be interrupted with the A.C. contactor actuating coil in the circuit by circuit control, control the closure of the A.C. contactor main contacts that can be interrupted power circuit by actuating coil.Do not need electricity consumption and when breaking down, any one normally closed moving disconnected push-button switch is pressed, normally closed switch often becomes to be opened, and interrupt in the loop, and the A.C. contactor main contacts that makes it to control disconnects, and general supply breaks away from the load load.Temperature relay in the circuit can reach the temperature control temperature when fire occurring, relay normally closed (moving disconnected) circuit interrupts automatically.This normally closed switch circuit is not controlled and can not be interrupted the power load circuit.During actual installation, can be according to switching circuit operation principle of the present invention, according to lighting system actual load situation assembling power distribution equipment.
The present invention is applicable to the lighting system of the three-phase four-wire system distribution of transformer neutral point grounding system in the electric power system or isolated neutral system.It has fundamentally eliminated the inessential loss that produces when circuit is not worked, and solve when emergency takes place, the problem that can not in time cut off the power supply, thus make each link of whole lighting system can be safely, economic, stable operation, whole lighting system is played a supervision effect.Through experiment test, safe in utilization, convenient, fast, can improve not changing on the available circuit basis, cost is low, is easy to install, and thoroughly eliminates the accident potential of available circuit, avoid increasing the input of primary energy, a large amount of energy have been saved in the duplication of production of secondary energy sources.

Below in conjunction with accompanying drawing the present invention is described in further detail.
Embodiment:
General supply one end ground connection, the fuse RD in the termination main distribution board, house lead in switch 1HK, fuse link DK draws three circuit herein.A circuit is uninterrupted power load circuit.Threephase switch 4HK on the distributor cap and fuse link DK connect uninterrupted power load; Second circuit is for can be interrupted the power load circuit, threephase switch 2HK on the distributor cap and fuse DK deliver to power supply the main contacts of A.C. contactor, connect three-phase system combination switch 3HK and fuse DK in the distribution board then, last connected system can be interrupted power load; Article three, be the multipoint control switch circuit.Molten electrical equipment DK of insurance and normally closed moving disconnected push-button switch TA, connection is often started and is closed moving switch QA, A.C. contactor subsidy contact C in parallel
oThis point is for often starting chalaza, continue three contactor actuating coil 1C of series connection, 2C, 3C, alternately connect normally closed switch TA1, temperature relay TK1, normally closed switch TA2, temperature relay TK2 normally closed switch TA3, temperature relay TK3 normally closed switch TA4, temperature relay TK4 then, form 220 volts of control switch circuit of electricity mutually.
