Abstract
The invention provides an intelligent centralized type emergency power supply which comprises a main power supply, an auxiliary power supply and a switching module, wherein the main power supply is connected in series with a voltage switching circuit and a protective circuit in sequence, and is connected with electricity utilization equipment; the voltage switching circuit is connected with a charging circuit; the charging circuit is connected with the auxiliary power supply; the auxiliary power supply is connected with the switching circuit; the switching circuit is formed by connecting a switch component with a detection control unit in series; the auxiliary power supply is connected with the switch component; the switch component is further connected with the electricity utilization equipment; the detection control unit is connected with the voltage switching circuit. Through the adoption of the emergency power supply, the switching speed between the main power supply and auxiliary power supply can be increased; in the case of mains supply failure, power can be discharged from the emergency power supply automatically through switching to be supplied to the electricity utilization equipment.
Description
Technical field
The invention belongs to field of electrical equipment, particularly a kind of emergency power supply.
Background technology
Modern construction more and more relies on electricity, and family life, work and manufacturing industry all need a large amount of electric energy.But, electricity in use very can not ensure not power-off really, when civil power is due to fault power-off or when being starkly lower than minimum voltage needed for load, productive life and the study of life will be had a strong impact on, great inconvenience is caused to life, even bring huge economic loss, for this reason, people have invented emergency power supply, but, emergency power supply is intelligent not, can only by manually going to open emergency power supply after fault occurs, such as flashlight etc., these emergency power supplies can not access family or workplace electric wire main line, the various problems that municipal power failure is brought can not be solved in time.
Summary of the invention
The object of this invention is to provide a kind of intelligent concentrated emergency power supply, to solve the problem of the intelligence not that existing emergency power supply exists.
For achieving the above object, the present invention is by the following technical solutions:
A kind of intelligent concentrated emergency power supply, comprises main power source, from power supply, handover module, described main power source is in series with voltage conversion circuit, protective circuit successively, then connects power consumption equipment; Described voltage conversion circuit is connected with charging circuit, charging circuit is connected with from power supply, commutation circuit is connected from power supply, described commutation circuit has switch block and detection control means to be composed in series, describedly to be connected from power supply with switch element, switch element is also connected with power consumption equipment, and described detection control means is connected with voltage conversion circuit.
Described switch block is metal oxide semiconductor field effect transistor.
Described protective circuit comprises overcurrent, overvoltage and short-circuit protection circuit.
Described main power source is civil power.
Described from power supply be storage battery.
The invention has the beneficial effects as follows: when primary power source de-energizes, the handover module work in system, detects primary power source de-energizes by detection control means, and switch block work is switched to from power supply, completes switching, ensures the normal operation of power consumption equipment; The present invention can improve main power source and the switch speed from power supply.Intelligent concentrated emergency power supply provided by the invention can automatically switch to when municipal power failure and discharge by from power supply, and electricity supply and use equipment uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in drawings, a kind of intelligent concentrated emergency power supply, comprises main power source 1, from power supply 2, handover module 3, described main power source 1 is in series with voltage conversion circuit 4, protective circuit 5 successively, then connects power consumption equipment 7; Described voltage conversion circuit 4 is connected with charging circuit 6, charging circuit 6 is connected with from power supply 2, commutation circuit 3 is connected from power supply 2, described commutation circuit 3 is composed in series by switch block 31 and detection control means 32, describedly to be connected from power supply 2 with switch element 31, switch element 31 is also connected with power consumption equipment 7, and described detection control means 32 is connected with voltage conversion circuit 4.
Switch block 31 is metal oxide semiconductor field effect transistor.
Protective circuit 5 comprises overcurrent, overvoltage and short-circuit protection circuit.
Main power source 1 is civil power; Be storage battery from power supply 2.
When civil power power-off, the handover module work in system, detects primary power source de-energizes by detection control means, and switch block work is switched to from power supply, completes switching, ensures the normal operation of power consumption equipment.
