Abstract
The utility model relates to a ballast and a transformer which are provided with double protection, which are suitable for halogen lamps, mercury lamps, sodium lamps, daylight lamps, etc. The utility model is composed of an illuminating lamp, the ballast and the transformer which are connected in series with a short circuit protection device, and thermal protectors which are connected in series with the return circuits of the ballast and the transformer. One end of a fast fuse is connected with a power supply, and the other end of the fast fuse is connected with the other end of the power supply after connected in series with the thermal protector, an electrical inductance current limiter, and a daylight lamp pipe; one end of the fast fuse is connected with the power supply, the other end of the fast fuse is connected with the other end of the power supply after connected in series with the thermal protector through the original edge of the transformer, and the halogen lamp is connected in series with a subsidiary edge coil of the transformer. The thermal protector can prevent the temperature of the ballast and the transformer from rising with no limit in failure; the fast fuse cuts the power supply when short circuit current is too large, and protects electric appliances from damage. The utility model has the advantage of safe and reliable use.
Description
The utility model relates to a kind of ballast with protective device, transformer, illuminating lamp ballast, the transformer of the band duplicate protection that suit installation on illuminating lamps such as Halogen lamp LED, mercury lamp, sodium vapor lamp, fluorescent lamp especially, uses.
Various types of illuminating lamps in use, Chang Yin is short-circuited and makes coil heating and damage fluorescent tube in the circuit, when serious even can cause fire and electric shock accidents.
The patent No. 96206911.6 " illuminating lamp ballast, the transformer of band short-circuit protection " also provides a kind of ballast with protective device, transformer, but reliability not enough.Line short has only when the coil heating temperature is very high and just can move, and open circuit shields.
The purpose of this utility model is to provide a kind of illuminating lamp ballast with duplicate protection, transformer, and protective device does not take effective usage space, and it is easy to use, and good reliability, safety play double protection to electrical appliance.
The utility model is achieved in that the illuminating lamp ballast, transformer of band duplicate protection be made up of lighting and the ballast, the transformer that are in series with short-circuit protection, also comprise the thermal protector that is serially connected in ballast, the transformer circuit, short-circuit protection is fast acting fuse a. fast acting fuse one a termination power switch, is connected with other end of mains switch behind end serial connection thermal protector, current limit by inductance device, the fluorescent tube in addition; B. fast acting fuse one termination power switch is held in addition by being connected with other end of mains switch behind the transformer primary coil serial connection thermal protector, and Halogen lamp LED is serially connected in the transformer secondary coil.
Fig. 1. structural representation of the present utility model (fluorescent lamp).
Fig. 2. structural representation of the present utility model (Halogen lamp LED).
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Current limit by inductance device (3) is with of the prior art the same.Thermal protector can be thermistor (2) or thermal cut-off, can be recovery type or irrecoverable type.
Connect starter S between fluorescent tube (4) two filaments, current limit by inductance device (3) is connected with fast acting fuse (1) with fluorescent tube (4) and thermistor (2) respectively, fast acting fuse (1) end in addition is connected with mains switch one end, and the end in addition of fluorescent tube (4) is connected with the end in addition of mains switch.
The employed transformer of Halogen lamp LED (6) (5) is the same with prior art.Halogen lamp LED (6) is serially connected in the secondary coil of transformer (5), fast acting fuse (1) one termination power switch, and other is connected by other end of transformer (5) primary coil serial connection thermistor (2) back and mains switch by end.
Thermal protector can or be close to coil or be close to iron core in the coil of current limit by inductance device (3), transformer (5); or be placed in the inner casing of ballast and transformer or in the medium of filler; the position of thermal protector and fast acting fuse is commutative, but must be connected in the loop.
During use, during as if electrical appliance illuminating lamp generation overcurrent or short trouble, temperature is elevated to a certain degree in circuit, and thermal protector will move, and the while fast acting fuse is action power dump also, prevents the generation of fire incident and electric shock accidents.
The utility model is compared with prior art: because increased weak point in original ballast, transformer circuit Line protection device and thermal protector double protecting device, one has fault to take place in the circuit, and two protective devices just divide The work of not moving if the high thermal protector of temperature moves earlier, can not allow the unconfined rising of temperature and damages electrical appliance, If overcurrent is big, fastp-acting fuse moves earlier, at once cuts off electric current, has double insurance to play the effect of protection, Use safety, reliable. It directly is connected in series in the line simultaneously, does not occupy in addition effective usage space, no Need other wiring, easy to use.
Claims (2)
1. the illuminating lamp ballast with duplicate protection, transformer, form by lighting and the ballast, the transformer that are in series with short-circuit protection, it is characterized in that also comprising the thermal protector that is serially connected in ballast, the transformer circuit, short-circuit protection is fast acting fuse (1) a. fast acting fuse (1) one a termination power switch, and other is connected by end to hold serial connection thermal protector, current limit by inductance device (3), fluorescent tube (4) back and mains switch in addition; B. fast acting fuse (1) one termination power switch is held in addition by being connected with other end of mains switch behind transformer (5) the primary coil serial connection thermal protector, and Halogen lamp LED is serially connected in transformer (5) secondary coil.
2. ballast according to claim 1, transformer; it is characterized in that thermal protector is thermistor (2) or thermal cut-off; can be recovery type or irrecoverable type; thermal protector can be around current limit by inductance device (3); in the coil of transformer (5) or be close to coil; or be close to iron core, or put into the inner casing of ballast, transformer or the medium of filler.
