Description
Technical field
The utility model relates to a kind of lighting electricity saving device of being made up of autotransformer.
Background technology
In energy-saving and emission-reduction advanced technology of applying at present and equipment, the illuminating energy-saving product occupies suitable proportion in economize on electricity market, and has brought into play the economize on electricity effect of good source.But the general lighting electricity-saving appliance often just is connected on illumination in the control circuit, and in the electricity-saving appliance external circuit has only a kind of state of economize on electricity, can't satisfy the requirement that when lighting electricity saving device breaks down lighting load continues reliable and secure operation.Owing to have such shortcoming, make lighting electricity saving device be subjected to considerable restraint, thereby the source electricity-saving function of lighting electricity saving device extensively do not brought into play as yet in the application in economize on electricity field.
The utility model content
The purpose of this utility model provides a kind of limitation simple in structure, easy to operate, no, the cheap lighting electricity saving device circuit of investment.Solution shortcoming that lighting load can't normally be moved when lighting electricity saving device breaks down and problem guarantee continuity, reliability and the fail safe of illumination, enlarge the application of lighting electricity saving device, bring into play the electricity-saving function of lighting electricity saving device to greatest extent.
In order to achieve the above object, the utility model provides a kind of lighting electricity saving device circuit, comprises a circuit breaker, a change over switch, two auxiliary relays, three contactors, a fuse and an autotransformer that circuit connects.
Described circuit breaker has the function of connecting and cutting off the electricity supply.The circuit breaker that closes, major loop and control loop power connection are charged, and power supply indicator lights; Shutdown device, major loop and control loop dump.Described change over switch has economize on electricity and bypass and stops (neutral gear) three gears, is used for the lighting electricity saving device state and switches.Described auxiliary relay cooperates technological requirement exactly, and execution command is transmitted signal, changing the operating state of control circuit, thereby realizes the purpose of set control or protection.Described A.C. contactor promptly utilizes main contacts to open and close circuit, carries out control command with auxiliary contact.Described fuse, i.e. insurance (silk) prevent to transship and open circuit as the error protection of lead and equipment, and it can satisfy the technical conditions relevant with electric equipment.Described autotransformer is the main frame of lighting electricity saving device, and balance, inhibition harmonic wave, raising power factor by three-phase output voltage under the prerequisite that satisfies the lighting load needs, reach the purpose of automatic economize on electricity.
The circuit that the utility model provides, it can overcome the shortcoming that the general lighting electricity-saving appliance can only series operation, and the problem that light source can't normal illumination when solving the lighting electricity saving device fault guarantees continuity, reliability and the fail safe of light source load.It can eliminate the misgivings to lighting electricity saving device malfunction influence operation, enlarges the market application of lighting electricity saving device, brings into play the source electricity-saving function of lighting electricity saving device to greatest extent.This circuit design and manufacture craft are simple and direct, and operation of equipment is convenient.The circuit that the utility model provides has the characteristics of novelty, advance, practicality, reliability.
Description of drawings
Fig. 1 is the electrical block diagram of a kind of lighting electricity saving device circuit of providing of the utility model.
Embodiment
Followingly specify better embodiment of the present utility model according to Fig. 1:
As shown in Figure 1, the utility model provides a kind of lighting electricity saving device circuit, comprise a circuit breaker that circuit connects 1, change over switch 2, two auxiliary relays 301 and 401,402 and 403, fuses of 302, three contactors 5, an autotransformer 6, form the conversion that economize on electricity, bypass, neutral gear stop three kinds of states.
The described electricity-saving state circuit breaker 1 that closes exactly, major loop and control loop are charged, and power supply indicator is bright.When control switch 2 was pushed the economize on electricity gear, the control power supply made contactor 402 get electric adhesive through auxiliary relay 301 normally closed contacts; In the time of contactor 402 adhesives, becoming closing point after 402 adhesives of contactor 402 auxiliary contact normally open contactors makes contactor 403 get electric adhesive, in the time of contactor 403 adhesives, often open (closed) through contactor 403 auxiliary contacts, auxiliary relay 302 gets electric adhesive, through the normally closed contact of auxiliary relay 301 and the normal opened contact of auxiliary relay 302 (closed) the economize on electricity indicator light is lighted, show the realization of lighting electricity saving device electricity-saving function.
When described bypass condition pushed the bypass gear with control switch 2 exactly, the control power supply made contactor 401 adhesives through auxiliary relay 302 normally closed contacts; In the time of contactor 401 adhesives, make auxiliary relay 301 get electric adhesive through contactor 401 auxiliary contact normally open contactors 401 (becoming closing point after the adhesive), at this moment power supply lights the bypass indicator light through the normal opened contact (closed) of auxiliary relay 302 normally closed contacts and auxiliary relay 301, show that lighting electricity saving device major loop and control loop all disconnect, the lighting electricity saving device bypass functionality is realized.
